Embodiment Construction

[0018] The shown clamping device 1 is positively inserted into the open end of the hollow spindle of the balancing machine for this purpose. The clamping device 1 has a receiving unit 2 consisting of two parts connected to each other by a screw connection, a receiving part 3 and a bearing part 4 . The flange 5 with fastening bores 6 on the receiving part 3 is used to fasten the receiving unit 2 on the end face of the hollow spindle. For precise centering relative to the hollow spindle, the receiving part 3 is provided with a centering surface 7 on its outer side. A through-hole 8 extends axially through the receptacle 3 , which leads to a central receptacle opening 9 which is designed to receive a standardized hollow bevel-cone coupling shaft of a tool. It is of course also possible to form the receptacle 3 which also has a differently designed receptacle opening for receiving a differently shaped clutch shaft.

[0019] In the through-opening 8 there is a clamping jaw 10 , w...

Abstract

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).

Description

technical field [0001] The invention relates to a clamping device for clamping in a balancing machine a machine part defined to rotate about an axis of rotation, in particular a tool holder of a drilling, milling or grinding tool. Background technique [0002] Clamping devices of the above-mentioned type are mainly used in balancing machines for clamping tools that can be driven in rotation at high rotational speeds. High demands are placed on the balancing of such tools, since an insufficiently balanced tool impairs the machining quality. In order to be able to meet the high demands on the balancing quality, precise centering of the tool to be balanced requires the aid of a clamping device arranged on the spindle of the balancing machine. [0003] A clamping device for clamping a tool holder provided in a balancing machine is known from WO 00 / 45983 A1, wherein a base unit fixed on a machine spindle driven in rotation about an axis of rotation has a central A receiving ope...
