Clamping device for tools and tool holders has coupling device between operating device which is non rotatable relative to spindle and operating rod which is rotatable with same

摘要

The clamping device has a rotary driven spindle (13) with operating rod (16) actuated by an operating device (20) which is mounted non-rotatable relative to the spindle and is coupled through a coupling device (30) to the operating rod which does rotate with the spindle. The coupling device produces a separation between the rotating rod and the non-rotating operating device on one side and produces a coupling between same on the other side. The operating device is formed from a spindle unit with electric drive motor and reduction gear.
