clamping equipment

Abstract

The invention relates to a clamping device (1) for clamping a tool holder for drilling, milling or grinding tools in a balancing machine, which device includes a receiving opening (9) with a coupling shaft for the tool holder and a clamping device. Accommodating unit (2) of the clamping pliers (10), the shaft (20) of the operating unit (18) for operating the clamping pliers (10) is slidably guided in a central bore (19) of the accommodating unit (2) . The shaft (20) has a force transmission body (22) on one end, and a plurality of pressure springs (30, 31) are supported on the force transmission body (22). The plurality of pressure springs (30, 31) can be used to Clamp with clamp (10). The compression springs (30, 31) are arranged and / or arranged in such a way that the spring force acting on the force transmission body (22) when the clamping jaw (10) is clamped is transmitted asymmetrically with respect to the axis of the shaft (20). The force body (22) is loaded.

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...
