Abstract
A workpiece clamping device for a machine tool is provided, which has a base, first and second clamping jaws between which a workpiece is clampable, a drive, and an actuating element which is displaceable relative to the base and which is coupled to the first clamping jaw. A movement of the actuating element is brought about by the drive and the actuating element brings about a displacement of the first clamping jaw. A transmitter is arranged on the actuating element and is displaceable together with the actuating element and is displaceable relative to the actuating element. A first stop and a spaced-apart second stop are provided, between which stops the transmitter is displaceable together with the actuating element. When the transmitter abuts against the first or second stop, the transmitter is displaceable relative to the actuating element. A sensor is provided for detecting one or more positions of the transmitter.
