Abstract

The present clamping device is used for clamping workpieces, in particular of machined blanks of copper or graphite. The clamping device consists essentially of a carrier body (1) with a plane surface (2) for clamping the workpieces and at least two in the carrier body (1) mutually displaceably guided clamping jaws (4). In the jaw members (5) so-called pendulum jaws (6) in cylindrical recesses (7) are pivotally mounted, which optimally adapt to the side walls of blanks with non-parallel side walls. To keep the preparatory work for the clamping of the blanks as small as possible, the recesses (7) from above from symmetrically inclined to each other obliquely outwards and embedded therein pendulum jaws (6) on its underside by springs (8) are supported, so that the Pendulum jaws (6) are pulled down when pressed against the workpiece against the spring force.
