ABSTRACT:
A pneumatic quick vise utilizes a compressed air source to control operation of its jaws for high speed clamping and releasing of working pieces at high efficiency. The vice include a piston operated by the compressed air source to drive a booster mechanism and driving a screw rod to operate the vice, and the vice further includes a pivot for its movable jaw at a reactive side to prevent upward raising of a working piece during clamping and a cushion arrangement at both sides of the piston to minimize impact from quick displacement of the piston in order to prolong service life and improve machining accuracy.
