ABSTRACT:
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).
