ABSTRACT:
The invention relates to a clamping device for removably mounting a tool (3) or a tool fixture in a receiving part (1). Said clamping device comprises several pincers elements (33) which are concentrically arranged around a central axis (32) within the receiving part (1) and are impinged upon by a tension spring (39) so as to be moved into a clamping position in order to brace the tool (3) or the tool fixture. In order to be able to automatically replace a tool without using much force and energy, an axially movable closing element (17) is assigned to the pincers elements (33). Said closing element (17) impinges the pincers elements (33) in a forward position that is advanced in the direction of the pincers elements (33) for mounting purposes in the clamping position thereof, which is swiveled inward by means of the tension spring (39), while being movable into a retracted position with the aid of a detaching device (12, 16, 45, 46, 47) in order to release the pincers elements (3).
