A drive for a machine vice having a vice body (8), a fixed jaw (9) and a movable jaw (4), a drive spindle (1) rotatably mounted in a thrust block (6) at one end of the vice body adjacent the movable jaw, a slide or drive nut (29) for the movable jaw cooperatively engaging drive screw threads (30) on the spindle so that rotation of the latter actuates the movable jaw, these parts extending on one side of the thrust block (6), a threaded sleeve (11) mounted in the thrust block, an extension (13) on the drive spindle extending rotatably and slidably through the thrust collar, a chamber drive unit (15) threadedly engaged (14) with extension (13) at one end and threadedly engaged at the other end with crankshaft (16) driven at its outer end by a crank (3) so that the crank rotates the drive spindle. A power amplifier (2) is mounted between and engaged with the crankshaft and drive spindle within the chamber drive unit and a releasable ball type clutch (35) is provided between the crankshaft and chamber drive unit so that force on the crankshaft produced by the crank rotatably drives the chamber drive unit which rotates the drive spindle up to a predetermined torque, after which the ball clutch disengages and the crankshaft alone rotates to operate the power amplifier to move the drive spindle linearly.

Drive for a machine vice

The invention relates to a machine tool vice having a vice body and a slide guided in the vice body, with a clamping mechanism working between the vice body and the slide, in which there are two jaws, which are connected with the vice body and the slide respectively and of which the fixed jaw is designed in a bridge-like design and secured such that it can be detached. The clamping mechanism is arranged beneath the clamping zone formed by the jaws, and the slide is arranged in a longitudinal recess, open at the top, and extending generally over the entire length of the vice body. The vice body or the slide is provided with several means of retention which can be used selectively for the jaws. Alternatively several interchangeable jaws be used selectively, and all jaws are mounted on the vice body and the slide such that they can be detached.

Machine tool vice

A high pressure clamping device having a screw vice body, a fixed jaw arranged on one of the ends of the screw vice body, and a slide, which is retained in a guide on the screw vice body and carries a jaw movable relative to the fixed jaw. A reaction block is provided on the other end of the screw vice body to co-operate with a tensioning drive of the movable jaw, which drive consists of a force intensifier or slave unit and a threaded spindle, which can be driven by means of a common crank. The threaded spindle engages in a spindle nut of the slide. The movable jaw is positioned above the force intensifier in the retracted position of the slide and is arranged in the screw vice body between the reaction block and the threaded spindle. The spindle nut which is formed in an extension of the slide, exerts a forward twisting and downwardly directed tensioned pull on the movable jaw in its clamping position.
