Abstract

For controlling the locking of the rotatable tool holder of a tool turret, the angular position of the tool holder is determined by a rotating transmitter. The rotating transmitter is rotated corresponding to the rotary movement of a control and synchronization device. Digital signals are produced with the aid of the rotating transmitter. Each digital signal is associated with one angular position of those which may be selected. With each of these signals, the indicator is changed in those two angular positions of the control and synchronization device for locking and unlocking of the tool holder at each of its angular positions. The indicator is changed by the rotary movement of the device in one or the other direction out of the associated angular position and into the angular position associated with the locking of the tool holder. These rotary transmission signals are used to control the locking. The control and synchronization device has a first and a second driven part which are nonrotatable relative to the tool holder, and a driving part which is driven when the drive motor is connected. The driving part is coupled with no rotary movement form-locking with one driven part.
