(54) Pneumatic vice with incorporated control and safety device


(57) These vices consist of a base (1) containing special single-action pneumatic groups (2) acting on a slide (3) that slides in a channel machined on the back of the base. Contained in the base, without requiring any increase in size, is the command (4) for the adjustable loads of pre-clamping and clamping and of a check valve located before the pistons.
The groups transmit to the slide their thrust, multiplied by the 90° levers (5) with fulcrum in the base, and push the slide through cylindrical surfaces centered at the ends of the short arms and a minute travel (Δ) in such a way that the mating points between the 90° levers and the slide remain always on the same plane. The mobile shoulder (7) can be locked onto the back of the slide through special means in adhesion to the part to the clamped.
Lateral springs (10) in the slide provide for its return. A screw (18) serves to push the slide by (Δ) in the absence of air.
