ABSTRACT:
A tool turret has a locking mechanism part which can slide axially relative to the turret head. The locking mechanism part is aligned with annular gears of the turret head and of the housing. In its locked position, an annular gear on the locking mechanism part mates with the gears of the turret head and housing. An axial drive engages a control member which is rotatable relative to the locking mechanism part and has at least one curved sector. The curved sector has a shape for thrusting the locking mechanism part into its locked position by a continuation of the rotary movement of the control member relative to the locking mechanism part in the direction of the preceding rotary movement setting the new angular position of the turret head.
