ABSTRACT:
In the clamping device a clamping head rigidly attached to the rotating spindle is provided between the rotating spindle and the tool holder which has a plurality of adjustable clamping pieces for holding the tool holder on the clamping head. A clamping rod penetrating the clamping head is provided for the tool holder in the hollow rotating spindle. This clamping rod is slidable axially under power operation, is coupled with a central clamping member of the tool holder and is rotatable relative to the rotating spindle. This clamping rod is couplable and uncouplable with the clamping member by rotation. A clamping pipe which is guided axially slidably and nonrotatably relative to the rotating spindle moves and adjusts the clamping pieces. The clamping rod is engaged in the rotation direction with the clamping pipe by the gear unit which converts the axial motion of the clamping pipe to a rotation of the clamping rod. Thus a sliding of the clamping pipe in the sense of a fixing and/or loosening of the tool holder on the clamping head rotates the clamping rod in the sense of a coupling and/or uncoupling to the clamping member.
