Clamping device for clamping e.g. hollow workpiece for rotation during machining processing, has sleeve section including axial distance corresponding to sum of another axial distance of another sleeve section and axial deformation distance

摘要

The device (2) has a clamping sleeve (5) and a sleeve-like counter clamping body (4) displaced against each other axial to an axis (A) in an axial clamping movement under action of axial clamping force. Working clamping surfaces (61, 71) and working counter clamping surfaces (41, 42) slide on each other during a part of the axial clamping movement. An axial distance of a sleeve section (6) corresponds to a sum of another axial distance of another sleeve section (7) and an axial deformation distance in an elastic deformation zone (8) during the axial clamping movement.
