Set of active components for the clamping on a pallet of a rough piece to be machined which incorporate the capacity of adjustment in height and in angular orientation

Abstract

 The set of active components comprises a first active component (1) provided with an operational part (10) adjustable in height, and a second active component (11) provided with an operational part (19) adjustable in angular orientation.

Description

[0001] The present invention relates to a set of active components for the clamping on a pallet of a rough piece to be machined which incorporate the capacity of adjustment in height and in angular orientation.

[0002] According to the known art described in the Italian patent application No. 22932 A/87 dated 10 December 1987 the active components of a clamping fixture for pieces arranged on a supporting pallet are placed one above the other directly or through a set of intermediate passive modular elements, which have a connecting function only, to anchoring elements adjustable in height and in angular orientation inserted screwably and unscrewably in corresponding threaded holes in the supporting pallet.

[0003] According to another solution described in an Italian patent application by the same Applicant on the same date the possibility is provided of abolishing the intermediate passive elements and of using, either as an alternative to or in combination with one another, modular-type anchoring elements which can be placed one above the other, two of which are adjustable in angular orientation and in height, respectively.

[0004] The object of the present invention is to accomplish a set of active components for the clamping on a pallet of a rough piece to be machined which incorporate the capacity of adjustment in height and in angular orientation.

[0005] According to the invention such object is attained through a set of active components for the clamping on a pallet of a rough piece to be machined, characterized in that it comprises a first and a second active component which can be directly inserted and clamped in corresponding cavities of a pallet or other supporting element and provided with operational parts adjustable in height and angular orientation, respectively.

[0006] In this way it is possible to do away with anchoring elements adjustable in height and in angular orientation, placed between the pallet and the clamping fixture's active components.

[0007] The features of the present invention shall be made more evident by the following detailed description of an embodiment illustrated as a non-limiting example in the enclosed drawings, wherein:

Fig. 1 illustrates an axial sectional view of an active component adjustable in height;

Fig. 2 illustrates an axial sectional view of an active component adjustable in angular orientation.

[0008] With reference to Fig. 1, the active component is indicated as a whole with 1 and comprises an internally hollow casing 2 terminating with a tang 13 inserted with a small clearance in a cylindrical cavity 8 of a pallet or other supporting element 5 provided with a slot 4 for housing a fastening pin 3 integral with the casing 2. In the casing 2 there is a bolt 21 with a hexagonal hollow head 6, which is screwed into an internally threaded bush 7 arranged and clamped in cavity 8. A sealing gasket 23 is placed between the casing 2 and the support 5. Another sealing gasket 9 is placed between the casing 2 and the bolt 21 to prevent the clamping fixture's control fluid, supplied through a hole 22 communicating with the cavity 8 (as described in the abovementioned patent application No. 22932 A/87 dated 10 December 1987), from seeping outside the casing 2.

[0009] The operational part or cap 10 of the active component is screwed onto the casing 2 in a manner adjustable in height. In particular the adjustment is made by loosening the bolt 21 and rotating the cap 10 until it reaches the desired height. The position is lastly fixed by again screwing up the bolt 21 into the bush 7.

[0010] With reference to Fig. 2, the active component is indicated as a whole with 11 and comprises an internally hollow casing 12 terminating with a tang 14 inserted with a small clearance in a cylindrical cavity 15 of a pallet or other supporting element 16. In the casing 12 there is a bolt 24 with a hexagonal hollow head 17, which is screwed in an internally threaded bush 18 arranged and clamped in cavity 15. A sealing gasket 25 is placed between the casing 12 and the support 16.

[0011] The casing 12 of the component 11, provided by way of an example with an operational part constituted by a lateral pin 19 screwed into a blind hole 20, is adjustable in angular orientation. Adjustment is made by loosening the bolt 24 and rotating the casing 12 until it reaches the desired angular position. The position is lastly fixed by again screwing up the bolt 24.

Claims
