ABSTRACT:
A tool turret has a housing and a revolving tool head which can be locked relative to the housing by means of gear teeth including annular toothed rings with axially extending teeth which can be interlocked in different rotational positions. A device having a cam drive controls the selective looking and unlocking of the gear teeth, the cam drive being arranged coaxial to the shaft. A Geneva wheel is provided to drive the head unlocked by the gear teeth. The cam drive has an annular groove in which rides a cam follower which is mounted on a axially movable, annular locking element which carries one set of teeth. The set of teeth can be removed axially to concurrently engage rings of teeth on the head and the fixed housing, locking the head.
