Abstract

For changing the tool disk connected detachably and rotatably to the housing of a tool turret, a work-locating fixture is provided. The tool disk can be moved out of its work setting in which it is coupled with the drive shaft for rotation by a rotary drive. The tool disk movement is in the axial direction of the drive shaft away from the housing until the tool disk reaches transfer position. The drive shaft and a tie rod coupled to the drive shaft are then rotated by the rotary drive out of a connected setting into a detached setting. In the detached setting, the connection between the tie rod, which tie rod is slidable in its axial position relative to the housing and the tool disk, is disconnected, so that the tie rod can then be lifted out of the tool disk. Subsequently, the tie rod can be brought into engagement with another tool disk and then can be rotated by the rotary drive out of the detached setting into the connected setting, in which the tie rod is connected to positively lock in axial directions the tie rod with the tool disk. As a result of relative movement between the housing and the tool disk, the tool disk can be brought into its work setting and then can be clamped tightly.
