Abstract

The circular tool (30) is clamped loosely between a flange (26) on a motor-driven hollow spindle (24) and a clamping flange (28), by a packet of Belleville washers (42). The final pressure is applied by pivoting a lever (32) operated cam (56), which acts on a tappet (58). The lever is moved from the closed position (Zu), to the open position (Auf). In the unclamped position, if the motor is energized, the tappet rotates, releasing the friction between it and the cam. The lever then moves into the clamped position.
