COMBINED ELECTROPLATED GRINDING WHEEL

Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of abrasive wheel tools. and more particularly to a combined electroplated abrasive wheel.

BACKGROUND

[0002] Firstly, if external cooling is adopted for equipment without an internal cooling water supply structure. an airflow barrier will be formed at an inner diameter, an outer diameter and a grinding surface of an end face of an abrasive wheel due to rotation of the abrasive wheel, blocking cooling water from entering a grinding region. Particularly, a high rotational speed leads to a strong airflow barrier, which is not suitable for a technical application of high-speed grinding. Further. in the case of external cooling, cooling water cannot act in a direction from the outer diameter to the inner diameter under the action of a centrifugal force, so that a cooling effect on a portion of the working end face close to the inner diameter is extremely poor. The prior art is shown in FIG. 1.

1. In an improved method, a body of the abrasive wheel is hollowed out as much as possible. and a hollowed-out region serves as a water passage, so that the cooling water is injected into an inner diameter cavity to cool the grinding surface along a radial direction from the inner diameter to the outer diameter under the action of the centrifugal force. When the body is hollowed out, it is necessary to ensure the connection strength of a "rib frame" of the remaining part, as the "rib frame" will also hit the cooling water during high-speed rotation to form a turbulent layer or water mist. such that the cooling water cannot enter the inner diameter cavity smoothly and a cooling water amount is negatively affected.

2. Even if the cooling water enters the inner diameter cavity, a part of cooling water still runs off due to penetration, and thus, the amount of cooling water passing through the inner diameter and the end face of the abrasive wheel under the action of the centrifugal force is also very small.

3. Due to the high machining difficulty of the body of the abrasive wheel and the high cost of machining, reconditioning the body of the abrasive wheel is a common method to reduce the cost. However, working procedures for performing reconditioning on the original body are complex. Working procedures such as deplating diamonds. finishing the body to satisfy precision requirements and replating the diamonds are required. An electroplating step is particularly complex; the productivity is low and the cost is high.

[0003] Secondly, for an abrasive wheel electroplated with diamonds, an abrasive material is disposed in a single layer. Since an exposed height of a diamond is less than half of its particle size, a space in the grinding region (a region in which the abrasive wheel is in contact ith a workpiece) is narrow and occupied and blocked by cuttings, so that the amount of cooling water passing along the radial direction from the inner diameter to the outer diameter under the action of the centrifugal force is very small. The finer the diamonds are, the more difficult for the cooling water to pass. thereby greatly limiting the cooling effect and further affecting the grinding efficiency.

[0004] Thirdly , since a diamond of a micro-powder wheel is often adopted for the abrasive wheel electroplated with diamonds. in order to ensure normal operation of the abrasive wheel. it is required to machine the body of the abrasive wheel with high-precision machining equipment so as to satisfy higher machining precision requirements. If the precision is not satisfied. a diamond layer is prone to perforation and delamination, the workpiece may be burnt and broken, and the body may be damaged, so that the times by which the body may be reconditioned is reduced or the body even cannot be reused.
Also it is know the following Prior Art document CN108161777, published on June 15,'2018. This document discloses a pressurised internally cooled grinding wheel that includes a grinding wheel body, a grinding section, a coolant injection section, and a coolant passageway. The coolant passageway connects to the grinding wheel body and includes a coolant buffer interval. The grinding wheel body consists of an upper and lower mating body, with the upper body detachable from the lower body. The document also describes various features of the coolant passage, such as its arcuate shape, semi-circular cross-section, and possible attachment mechanisms for the grinding section. However, comparing with this (D1) document, our invention introduces a combined electroplated abrasive wheel, where the electroplating component is securely attached to the body using a combined connection method involving an absorption member (magnets and plugs). Unlike the Prior Art, which focuses on cooling and detachable grinding sections, our invention provides a detachable electroplating component that allows for easy replacement of the abrasive disc body with different particle sizes. This unique connection increases reusability, reduces damage, and enhances productivity.

SUMMARY

[0005] In order to overcome the shortcomings in the prior art, the technical problem to be solved by the present invention is to provide a combined electroplated abrasive wheel.

[0006] In order to solve the above technical problem, the technical solution of the present invention is as follows. A combined electroplated abrasive wheel includes a body and an electroplating component for electroplating a workpiece, wherein the electroplating component is connected to the body in a combined manner, as defined in claim 1.

[0007] The combined electroplated abrasive wheel of the present invention has the following beneficial effects. The electroplating component disposed on the abrasive wheel may be connected to the body in the combined manner without additionally disposing a "rib frame" structure, thereby avoiding a problem that cooling water in the abrasive wheel having the "rib frame" structure cannot smoothly enter an inner diameter cavity and affects a water amount. The interior of the abrasive wheel is hollowed out as much as possible, thereby increasing the water amount of the inner diameter cavity. Further, the electroplating component may be detached from the body, thereby realizing replacement of components, replacing a working procedure for reconditioning the original body, reducing a damage to the body, increasing a reuse rate of the body and the productivity, and lowering the cost.

[0008] Based on the above technical solution, the present invention may further include the following improvements.

[0009] Further, the first method for connecting the electroplating component to the body in a combined manner is as follows. The electroplating component includes a first connection disc, an absorption member, a first electroplated abrasive disc body and a first diamond plating layer; the body includes a water inlet end surface and a hollow annular groove, wherein the water inlet end surface is an annular plate structure with a first water inlet in the center; an outer diameter of the water inlet end surface and an outer diameter of the annular groove are equal and coaxially connected into a whole; the water inlet end surface is connected to a top surface of the annular groove, and a hollowed-out region is formed between the water inlet end surface and an inner annular wall of the annular groove; the first connection disc and the first water inlet are oppositely placed in the hollowed-out region and detachably connected to the water inlet end surface; a gap is reserved between the first connection disc and the inner annular wall of the annular groove to form a water passage; the absorption member is disposed in the annular groove; the first electroplated abrasive disc body is adsorbed at the outer side of a bottom surface of the annular groove through the absorption member; the first diamond plating layer is attached to the outer surface of the first electroplated abrasive disc body; and the first connection disc includes a plurality of blade components that is distributed on the side surface of the first connection disc close to the water inlet end surface in a vortex form.

[0010] The above further technical solution has the following beneficial effects. The body and the first connection disc of the abrasive wheel achieve an effect of external rotation and internal cooling. The first connection disc is disposed in the hollowed-out region, i.e., the inner diameter cavity; a gap formed by the inner annular wall of the annular groove, the outer diameter of the connection disc and the blade components serves as the water passage, and the cooling water is injected into the inner diameter cavity to cool a grinding surface along a radial direction from the inner diameter to the outer diameter under the action of a centrifugal force. The electroplated abrasive disc body is adsorbed on the body through the absorption member, and serves as a detachable and replaceable component, so that electroplated abrasive disc bodies of different particle sizes may be interchanged, thereby replacing the working procedure for reconditioning the original body, reducing the damage to the body, increasing the reuse rate of the body and the productivity, and reducing the cost.

[0011] Further, the second method for connecting the electroplating component to the body in a combined manner is as follows. The electroplating component includes a mandrel, a second connection disc, a press cover, a first abrasive body and a second abrasive body;

the second connection disc sleeves the lower end of the mandrel, and is fixedly connected to the mandrel; a plurality of shunting components of an arc blade structure are fixedly connected to the second connection disc and arranged in a vortex form;

the body sleeves the mandrel to form an annular water inlet passage with the mandrel; the body is located at the upper end of the second connection disc and fixedly connected to the second connection disc; a plurality of shunting passages is formed by the body, the plurality of shunting components and the upper end surface of the second connection disc, and arranged in a vortex form; the outer edge of the body extends downward to the lower end thereof and surrounds the second connection disc to form an annular water outlet with the outer side wall of the second connection disc; the water inlet passage is in communication with the plurality of shunting passages, and the plurality of shunting passages are all in communication with the water outlet;

the press cover is placed at the upper end of the body and fixedly connected to the body; the press cover sleeves the mandrel to form an annular second water inlet with the mandrel, and the second water inlet is in communication with the water inlet passage;

the first abrasive body is placed at the lower end of the body, and detachably connected to the body; and

the second abrasive body is placed at the outer side of the body, and detachably connected to the body.

[0012] The above further technical solution has the following beneficial effects. The cooling water can be guided to flow out via the water inlet, the water inlet passage, the shunting passages and the water outlet, thereby achieving the effect of external rotation and intemal cooling. The cooling water uniformly cools the grinding surface of the first abrasive body under the action of the centrifugal force, thereby effectively improving the cooling efficiency and the cooling effect. The mandrel, the second connection disc, the shunting components, the body, the press cover, the first abrasive body and the second abrasive body are easily manufactured with extremely low costs, thereby reducing the investment of machining equipment and lowering the machining difficulty and the machining cost, achieving easy replacement and operation before use, reducing the damage to the body, increasing the reuse rate of the body and the productivity, and lowering the cost.

DETAILED DESCRIPTION

[0015] Principles and features of the present invention will be described below in combination with the accompanying drawings. Embodiments are merely used to explain the present invention rather than limit the scope of the present invention.

[0016] In Embodiment 1, a combined electroplated abrasive wheel is provided, including a body 1 and an electroplating component for electroplating a workpiece, wherein the electroplating component is connected to the body 1 in a combined manner.

[0017] In the above embodiment, the electroplating component disposed on the abrasive wheel may be connected to the body in the combined manner without additionally disposing a "rib frame" structure, thereby avoiding a problem that cooling water in the abrasive wheel having the "rib frame" structure cannot smoothly enter an inner diameter cavity and affects a water amount. The interior of the abrasive wheel is hollowed out as much as possible, thereby increasing the water amount of the inner diameter cavity. Further, the electroplating component may be detached from the body, thereby realizing replacement of components, replacing a working procedure for reconditioning the original body, reducing a damage to the body, increasing a reuse rate of the body and the productivity, and lowering the cost.

[0018] Based on Embodiment 1, in Embodiment 2, as shown in FIGs. 2, 3, 4 and 6, the first method for connecting the electroplating component to the body is as follows.

[0019] The electroplating component includes a first connection disc 2, an absorption member, a first electroplated abrasive disc body 3 and a first diamond plating layer 301; and the body 1 includes a water inlet end surface 101 and a hollow annular groove 102, wherein the water inlet end surface 101 has an annular plate structure with a first water inlet 1011 in the center, an outer diameter of the water inlet end surface 101 and an outer diameter of the annular groove 102 are equal and coaxially connected into a whole, the water inlet end surface 101 is connected to the top surface of the annular groove 102, and a hollowed-out region is formed between the water inlet end surface 101 and an inner annular wall of the annular groove 102. The first connection disc 2 and the first water inlet 1011 are oppositely placed in the hollowed-out region and detachably connected to the water inlet end surface 101, and a gap is reserved between the first connection disc 2 and the inner annular wall of the annular groove 102 to form a water passage; the absorption member is disposed in the annular groove 102, the first electroplated abrasive disc body 3 is adsorbed at the outer side of the bottom surface of the annular groove 102 through the absorption member, and the first diamond plating layer 301 is attached to the outer surface of the first electroplated abrasive disc body 3; and the first connection disc 2 includes a plurality of blade components 4 that is distributed on the side surface of the first connection disc 2 close to the water inlet end surface 101 in a vortex form.

[0020] It is to be understood that the outer diameter of the annular groove 102 overlaps with the outer diameter of the water inlet end surface 101, and a diameter of the water inlet is less than an inner diameter of the annular groove 102, so that the connection disc 2 is connected to a position on the water inlet end surface 101 close to an inner diameter of the water inlet end surface 101.

[0021] Arrows in FIG. 4 indicate a flow direction of cooling water, that is, a radial direction from the inner diameter to the outer diameter.

[0022] In the above embodiment, firstly, the body 1 and the connection disc 2 of the abrasive wheel achieve an effect of external rotation and internal cooling, the connection disc 2 is disposed in the hollowed-out region, i.e., the inner diameter cavity, and the gap formed by the inner annular wall of the annular groove 102, the outer diameter of the connection disc 2 and the blade components serves as the water passage; and the cooling water is injected into the inner diameter cavity to cool a grinding surface along the radial direction from the inner diameter to the outer diameter under the action of a centrifugal force. Secondly, the electroplated abrasive disc body is adsorbed on the body through the absorption member, and is a detachable and replaceable component, so that electroplated abrasive disc bodies of different particle sizes may be interchanged to replace the working procedure for reconditioning the original body, thereby reducing the damage to the body, increasing the reuse rate of the body and the productivity, and lowering the cost.

[0023] The word "interchange" may be understood as follows: the body part may be considered as tooling, and rings (disks) of different particle sizes may be assembled on the tooling according to requirements to perform grinding. That is, the electroplated abrasive disc body 3 of a different particle size specification may be obtained by selecting the particle size specification for the diamond of the diamond plating layer 301 according to different requirements, and then is assembled on the tooling.

[0024] Based on Embodiment 2, in Embodiment 3, as shown in FIG. 2, the absorption member includes a plurality of cylindrical magnets 5 and a plurality of cylindrical plugs 6; the plurality of magnets 5 is placed around the bottom surface of the annular groove 102 at intervals; the magnets 5 and the plugs 6 are equal in number; the plurality of plugs 6 is in one-to-one correspondence with the plurality of magnets 5 and located above the corresponding magnets 5; and the magnets 5 are mounted on the bottom surface of the annular groove 102 through the plugs 6 by interference fit.

[0025] In the above embodiment, a plurality of magnets is disposed around the bottom surface of the annular groove 102 of the body and mounted on the bottom surface of the annular groove 102 through the plugs, and each magnet firmly adsorbs the electroplated abrasive disc body 3 on the body by a magnetic force to prevent the electroplated abrasive disc body 3 from being separated from the body during operation.

[0026] Based on Embodiment 3, in Embodiment 4, as shown in FIG. 3, a plurality of plug mounting holes 7 whose number is equal to that of the plurality of plugs 6 is formed in the water inlet end surface 101 of the body 1; the plugs 6 and the plug mounting holes 7 are equal in diameter, the plurality of plug mounting holes 7 is in one-to-one correspondence with the plurality of plugs 6, and each of the plugs 6 is inserted into the annular groove 102 from the corresponding plug mounting hole 7 respectively; and the lower end of the plug 6 is connected to the corresponding magnet 5, and the upper end of the plug 6 is clamped in the plug mounting hole 7.

[0027] In the above embodiment, the plug mounting holes 7 can facilitate mounting the plugs 6 on the magnets 5, and can accurately position the plugs 6.

[0028] Based on Embodiment 4, in Embodiment 5, as shown in FIG. 7 and FIG. 8, each of the blade components 4 includes a blade 401 and a water press plate 402; the blade 401 has a circular arc block structure, and the respective blades 401 are distributed on the connection disc 2 in a vortex form and close to the edge of the connection disc 2; the blade 401 and the connection disc 2 are integrally formed; the respective water press plates 402 are located at the water passage respectively and integrally disposed at the ends of the corresponding blades 401; and a thickness of the water press plate 402 gradually increases from front to back in a vortex rotation direction to form an oblique angle structure.

[0029] Specifically, as shown in FIG. 7, the respective blades 401 on the connection disc 2 are distributed in a clockwise vortex direction opposite to a rotation direction of the body 1. Alternatively, as shown in FIG. 8, the respective blades 401 on the connection disc 2 are distributed in a counterclockwise vortex direction. Thus, the connection disc 2 in a different blade form may be selected according to production and machining requirements.

[0030] In the above embodiment, the water press plate 402 generates a pushing force on the cooling water to ensure the water to flow rapidly through a small gap.

[0031] Based on Embodiment 5, in Embodiment 6, the combined electroplated abrasive wheel further includes a plurality of fixing screws 8 for connecting the body 1 and the connection disc 2, wherein the fixing screws 8 and the blades 401 are equal in number, and the plurality of fixing screws 8 is in one-to-one correspondence with the blades 401 and passes through the water inlet end surface 101 of the body 1 and the corresponding blades 401 sequentially from top to bottom.

[0032] It is to be understood that a plurality of screw holes is correspondingly formed in the blades 401 and the water inlet end surface 101 of the body 1, and the screws 8 are correspondingly inserted into the screw holes of the blades 401 and the screw holes of the water inlet end surface 101.

[0033] In the above embodiment, the connection disc 2 is detachably connected to the body 1 by the fixing screws 8, so that the mounting is rapid and convenient.

[0034] Based on Embodiment 2, in Embodiment 7, the first electroplated abrasive disc body 3 is of an annular sheet structure in a shape same as the bottom surface of the annular groove 102; and first water grooves 9 are densely formed in the first diamond plating layer 301, wherein each first water groove 9 has a strip groove structure.

[0035] In the above embodiment, the first electroplated abrasive disc body 3 may play a role of a chip pocket and a chip removal groove to greatly improve cooling and chip removal capacities, and thus is suitable for high-speed machining and conducive to substantially improving the grinding efficiency.

[0036] Based on Embodiment 7, in Embodiment 8, as shown in FIG. 11, the first water grooves arranged densely are in a radial shape, and an axis of each first water groove 9 passes through the circle center, so that the cooling water cools a grinding region (a region in which the abrasive wheel is in contact with a workpiece) along the radial direction from the inner diameter to the outer diameter under the action of the centrifugal force.

[0037] In Embodiment 8, as shown in FIG. 10, the first water grooves arranged densely are all inclined at the same preset angle, and a direction thereof helps the cooling water cool the grinding region along the radial direction from the inner diameter to the outer diameter.

[0038] Specifically, "inclined at the same preset angle" refers to that the axis of each water groove does not pass through the circle center, and the respective water groove are disposed in parallel and extend forward in a vortex rotation direction of the cooling water. Alternatively, "inclined at the same preset angle" refers to that the axis of each water groove does not pass through the circle center, and the respective first water grooves are disposed in parallel and extend backward in the vortex rotation direction of the cooling water.

[0039] It is to be understood that the circle center refers to a circle center of the electroplated abrasive disc body 3.

[0040] In Embodiment 8, as shown in FIG. 9, the first water grooves arranged densely have a crossed network structure, and generate a working face to form "network surface" grinding, so as to cool the grinding region.

[0041] In the above embodiments, three water groove forms are all passages through which the cooling water reaches the grinding working face (the diamond plating layer), and may improve cooling and chip removal effects in different extents. The cooling and chip removal capacities of the first water grooves in the radial shape, the inclined shape and the network shape are sequentially increased.

[0042] Based on Embodiment 7, in Embodiment 9, the combined electroplated abrasive wheel further includes a first elastic cushion 10 of an annular band structure, wherein the first elastic cushion 10 and the annular groove 102 are equal in inner diameter, and the first elastic cushion 10 is clamped between the bottom surface of the annular groove 102 and the first electroplated abrasive disc body 3.

[0043] In the above embodiment, the elastic cushion 10 slightly deforms under force, and thus may compensate the defects of equipment/abrasive wheel/assembly precision in a small range.

[0044] Based on Embodiment 9, in Embodiment 10, as shown in FIG. 5, the combined electroplated abrasive wheel further includes a positioning step 12; and the positioning step 12 is disposed around an inner diameter of the bottom surface of the annular groove 102 and axially extends toward the first electroplated abrasive disc body 3 to form a circular flange structure.

[0045] In the above embodiment, the positioning step 12 can position the elastic cushion 10 and the electroplated abrasive disc body 3 to prevent offset, thereby improving the precision and safety.

[0046] In Embodiment 10, in order to prevent the electroplated abrasive disc body 3 from loosening, an anti-rotation and anti-loosening component for fastening the electroplated abrasive disc body 3 on the body 1 is disposed.

[0047] As shown in FIG. 12 and FIG. 13, the abrasive wheel further includes the anti-rotation anti-loosening component. The anti-rotation anti-loosening component includes an electroplated abrasive disc body folded edge 14, a folded edge mounting groove 15 and an anti-loosening fastener 16. The electroplated abrasive disc body folded edge 14 is a square plate with a screw hole in a middle portion and disposed at the lower edge of the outer diameter of the electroplated abrasive disc body 3, the folded edge mounting groove 15 corresponding to the electroplated abrasive disc body folded edge 14 is disposed on the annular groove 102 of the body 1, and the electroplated abrasive disc body folded edge 14 is embedded into the folded edge mounting groove 15. The anti-loosening fastener 16 penetrates through the electroplated abrasive disc body folded edge 14 and the folded edge mounting groove 15 sequentially from outside to inside in a threaded connection manner to fix the electroplated abrasive disc body 3 on the body 1, so as to achieve an anti-rotation and anti-loosening effect of the electroplated abrasive disc body 3.

[0048] Specifically, a plurality of anti-rotation and anti-loosening components may be disposed circumferentially.

[0049] Based on the above Embodiments 1 to 10, in Embodiment 11, the combined electroplated abrasive wheel further includes a plurality of dismounting holes 11 for dismounting the first electroplated abrasive disc body 3; and the plurality of dismounting holes 11 is formed around an outer diameter of the bottom surface of the annular groove 102 at equal intervals.

[0050] In the above embodiment, the electroplated abrasive disc body 3 is pried up from the dismounting holes 11 to rapidly separate the electroplated abrasive disc body 3 from the body, thereby improving the production efficiency.

[0051] Based on the above Embodiments 1 to 10, specifically, as shown in FIG. 7, a circular connection protruding block for connecting a main shaft of external equipment is disposed at a central position of the first connection disc 2 and protrudes toward the water inlet end surface 101, and an equipment mounting hole 13 is formed in a central position of the circular connection protruding block.

[0052] In the above embodiment, the circular connection protruding block facilitates mounting the external equipment.

[0053] The combined electroplated abrasive wheel of the present invention has the following advantages.

1. The body part serving as the tooling may be used many times, thereby greatly saving body materials, reducing a machining volume of the body, and substantially reducing the consumption of the body materials and the machining cost.

2. The electroplated abrasive disc body of the diamond plating layer is easily manufactured by stamping at extremely low cost.

3. By the conventional machining methods such as stamping and rolling, it is very easy to machine dense water passages on the working face, and the passages may play the role of the chip pocket and the chip removal groove to greatly improve the cooling and chip removal capacities, and thus is suitable for high-speed machining and conducive to substantially improving the grinding efficiency.

4. The electroplated abrasive disc body is easily replaced before use.

5. The elastic cushion slightly deforms under force, and thus may compensate the defects of equipment/abrasive wheel/assembly precision in the small range.

6. The electroplated abrasive disc body may be produced in a simpler process with substantially reduced environmental protection expenses, and thus is suitable for automatic production.

[0054] Based on Embodiment 1, in Embodiment 12, as shown in FIGs. 14 to 24, a second method for connecting the electroplating component to the body is as follows.

[0055] The electroplating component includes a mandrel 17, a second connection disc 18, a press cover 20, a first abrasive body 21 and a second abrasive body 22.
