Patent ID: 10960505

Abstract:
A coupling device is for the reversible establishment of a drive connection between a driving unit (13) of a tool turret and a driven unit (46) of a tool receptacle (36) attached to the tool turret and in which a machining tool is able to be received. In a coupling position, a drive shaft (14) of the driving unit (13) is engaged by way of its external toothing (32) with an internal toothing of a driven shaft (44) of the driven unit (46). For a collision-free orientation of the external toothing (32) with respect to the internal toothing, before coupling, an aligning device is used. The orienting device passes through parts of the driven shaft (44) and has a control on one side for the cooperation with the drive shaft (13) and an aligner that is actuable by the control on the other side. The aligner is securable to the tool receptacle.
