SPANNDORN FUER DIE KOAXIALE AUSSENBEARBEITUNG VON WERKSTUECKEN MIT INNENVERZAHNUNG

摘要

In a mandrel for the coaxial external machining of workpieces with internal toothing, a reception sleeve with an external toothing corresponding to the workpiece toothing and having openings along the clamping length extending only on a portion of the circumference of the reception sleeve is provided wherein the reception sleeve is integral over the entire clamping length. A clamping member is disposed with tangential and radial play in the reception sleeve for engaging the workpiece toothing and is thereby turnable with respect to the reception sleeve by which the internal toothing of the workpiece can be brought to bear against the external toothing of the reception sleeve in a circumferential direction. The ends of the clamping member extend through the openings for engaging the workpiece toothing and circumferential parts of the reception sleeve and the ends of the clamping member alternate. The clamping member is turned between a clamping and an unclamping position by a rod.
