<p>The invention relates to a clamping device for clamping a tool ( 8 ), or tool holder in a working spindle ( 4 ), in particular, of a machine tool, comprising a drawbar ( 10 ), arranged to be displaced within the working spindle ( 4 ), a clamping set ( 12 ), arranged in the working spindle ( 4 ) and displaceable between a clamping position and a released position by means of the drawbar ( 10 ), a spring arrangement ( 14 ) provided for the drawbar ( 10 ) to generate the drawing force for the clamping set ( 12 ) and a releasing unit ( 17; 49 ), by means of which the clamping set ( 12 ) may be moved into the released position by the drawbar ( 10 ) against the force of the spring arrangement ( 14 ). According to the invention, a simplified operation of the clamping device may be achieved, whereby the releasing unit ( 17; 49 ) may be operated by an electrical actuator ( 62, 63, 53, 54 ).</p> |
