| 摘要 |
The invention relates to a workpiece clamping device for a machine tool (10), comprising a base (36); a first clamping jaw (38) which can be displaced relative to the base (36); a second clamping jaw (40), a workpiece (33) being clampable between the first clamping jaw (38) and the second clamping jaw (40); a drive (54); an actuating element (52) which can be displaced relative to the base (36) and is coupled to the first clamping jaw (38), wherein a displacing movement of the actuating element (52) is caused by the drive (54), and the actuating element (52) causes a displacement of the first clamping jaw (38); a transmitter (90) which is arranged on the actuating element (52), can be displaced together with the actuating element (52), and is movable relative to the actuating element (52); a first stop (100) and a spaced second stop (102) for the transmitter (90), said transmitter (90) being movable together with the actuating element (52) between said stops and being movable relative to the actuating element (52) when the transmitter (90) rests against the first stop (100) or against the second stop (102); and a sensor (110) by means of which one or more positions of the transmitter (90) can be detected. |
