摘要： 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).

摘要翻译：本发明涉及一种夹紧装置，用于将工具（8）或特别是机床的工作主轴（4）中的工具夹具夹紧，该工具包括一个设置成在工作主轴内移位的牵引杆（10） 4），夹紧组件（12），布置在工作主轴（4）中，并通过牵引杆（10）在夹紧位置和释放位置之间移动，为抽拉杆（10）设置的弹簧装置（14）以产生用于夹紧组件（12）和释放单元（17; 49）的拉力，夹紧组件（12）可借助于牵引杆（10）抵抗拉杆弹簧装置（14）。根据本发明，可以实现夹紧装置的简化操作，由此释放单元（17; 49）可以由电致动器（62,63,53,54）操作。
