Abstract
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.
