Abstract

A tool turret has a locking mechanism part axially slidable relative to the turret head with a face gear engaging face gears of the turret head and the housing in its locked position. The axial slidability of the locking mechanism part out of its locked position and the curtailibility of an opposing compression spring allows disengagement of the face gear of the locking mechanism part from at least one of the other two face gears. The force of the compression spring during the load on the turret head arising in disturbance-free operation is greater than the force working through this load on the locking mechanism part in the direction of disengagement of its face gear. In case of a collision with a stress exceeding the load capacity of the tool turret, the force of the compression spring is smaller than the collision force working through this load on the locking mechanism part in the direction of a disengagement of its face gear.
