ABSTRACT:
A clamping device, more particularly a toggle lever clamping device is devised for clamping workpieces and comprises an actuator cylinder (3) with a mounting head (23), said mounting head protruding from the piston rod and being provided with the control mechanism for the clamping arm (24) which is linked to said mounting head and, furthermore, two pressure medium supply lines and sensors for the final position with connecting lines. A positioning rod (5), provided with positioning elements (4), is arranged on the free end (1) of, and parallel to, the piston rod (2) and directed toward the actuator cylinder (3). The positioning path (W) of the positioning elements (4) extends within the region of the actuator cylinder (3). At least two sensors (6, 6') for the end position are located in the region of the positioning path (W). Both pressure medium inlet terminals (7, 8) are mounted on the free end (9) of the actuator cylinder (3) and the outlet lines (10) of the sensors (6) are also mounted in axial direction to the longitudinal axis (11) of the actuator cylinder (3) and on the free end (9) of the said cylinder (3).
