ABSTRACT:
The invention concerns a clamping connection for an interchangeable mandrel (1) and drive shaft (13) of a riveting tool. The connection comprises a connecting casing (15) to which the end of the drive shaft (13) is fastened on one side, while on the other side there is an open cavity in the casing (15), adapted for inserting the end of the interchangeable mandrel (1), in a transverse direction, until its expanded end part is inside the cavity and its axis lies along the axis of the drive shaft (13) and the casing (15), where the interchangeable mandrel (1) in this position is moveable in the direction of the common axis by the action of a pressure element across engaging, rolling surfaces arranged on the front surface of the expanded end part of the interchangeable mandrel (1) and on the adjacent surface of the pressure element, to the clamped position where the interchangeable mandrel (1) is gripped by its expanded end part in the cavity of the casing (15) by means of a correspondingly shaped surface, arranged in the cavity of the casing (15), with the possibility of axial movement and secured against rotation.
