End piece holder for vertical broaching machine

摘要

The holding arrangement has a security bolt (7) that is axially displaced relative to the carrier bolt (6). On raising the end piece holder the security bolt is pressed by the widened head (22) of the end piece (21) into a recess (19) of the switching bush (9) to achieve the closed position. In the open position a further recess (18) in the bush is aligned with the security bolt. The axis of symmetry of the security bolt lies of few millimetres above the axis of symmetry of the carrier bolt.
