Disclosed is a clamping device (1) for clamping a toolholder of a drilling, milling or grinding tool in a balancing machine, comprising;a receiver unit (2) having a receiving opening (9) for the coupling shaft of the toolholder and a collet (10), in which the shaft (20) of an actuator (18) for actuation of the collet (10) is slidably guided in a centrally located bore (19) of the receiver unit (2). The shaft (20) has at its one end a load-applying body (22) upon which a plurality of compression springs (30, 31) take support to enable the collet (10) to be tightened. The compression springs (30, 31) are arranged and/or configured in such a way that the spring loads acting on the load-applying body (22) with the collet (10) tightened act on the load-applying body (22) asymmetrically relative to the axis of the shaft (20). |

1. A clamping device for clamping a machine part configured to rotate about an axis of rotation in a balancing machine, comprising
a receiver unit having a receiving opening centrally located relative to the axis of rotation and adapted to receive axially therein a coupling shaft of the machine part, a collet arranged in the receiving opening, and an actuator guided on the receiver unit for axial movement relative thereto for actuation of the collet, wherein the actuator includes a shaft axially slidably guided in a centrally located bore of the receiver unit, wherein the shaft is carried in slide bushings with allowance for play, a clamping body at one end of the shaft for actuation of the collet, a load-applying body at the other end of the shaft, and a plurality of compression springs arranged between the receiver unit and the load-applying body, wherein the compression springs are arranged and/or configured in such a way that the spring loads acting on the load-applying body with the collet tightened are asymmetrical relative to the axis of the shaft. |
