Tool revolving unit for CNC controlled turning machine simulating Y axis with tool spindle having C-axis with feed rotation movement

摘要

The tool revolving unit is designed so that in the revolver head (22) is arranged a bearing system (52) compared to this rotatable about the operating axis (18), for a tool drive shaft (54) carrying the driven gear (64) of the angle drive (62). The tool drive shaft defines a work position for a tool reception (26) of the revolver head (22) assigned to a rotatable tool (32,34). A tool drive coupling is provided between the tool drive shaft (54) and the tool spindle (36) of the tool rotationally drivable respectively in a working position. The coupling has at least two coupling elements (100a,100b) disengageable or engageable relative to each other by the rotation of the revolver head about the operating axis (18) relative to the bearing system (52). One of which is connected rotation proof with the tool drive shaft, and the other is connected at least rotation proof with the tool spindle. The bearing system is connectable rotation proof by a first operable coupling (72b,16b) with the revolver head (22).
