ABSTRACT:
A workpiece handling device comprising a carrier mounting a plurality of pivot levers, each of which holds a clamping element. The pivot levers are pivotable about axes extending parallel to one another and their clamping elements are adapted to be synchronously moved towards and away from one another by a drive means common to all the pivot levers. In order to be able to move the clamping elements exactly in radial directions and in straight lines relative to the center of the workpiece and, at the same time, covering a large circular area, it is suggested that a clamping lever bearing the clamping element be articulatedly mounted on each pivot lever pivotable by the common drive means and that a pivoting device engaging each clamping lever be provided for pivoting the clamping lever in relation to the pivot lever in response to the pivoting movement thereof such that the clamping elements move in a manner known per se along straight lines intersecting at a center.
