A device for clamping a workpiece for the treatment in a grinding machine.

摘要

A device for clamping a workpiece for the processing in a grinding machine has a profiled clamping jaw (46) and a plunger (38), which are aligned in a tensioning axis and between which the workpiece is clamped. The plunger (38), together with one of these rotationally drivable servomotor (34) in a basic body (30) mounted. A guide block (40) is in the base body (30) can be linearly displaced parallel to the tensioning axis. The guide block (40) carries a guide sleeve (44), in which the clamping rams (46) and freely movable in axial direction is rotatably mounted. An actuating device transmits the axial clamping force on the clamping rams (46). The base body (30) is rotatable around a rotational axis of the workpiece (a - axis) of the grinding machine, the clamping axis of the rotary axis of the workpiece (a - axis) orthogonally intersects.
