Abstract
A servomotor-driven U-axis tool member rotation device for a boring and facing head is affixed to a machine by a bracket, and has a torque coupling slidable on the servomotor shaft. A cover is mounted to a pivot shaft on the bracket, and is rotated by the servomotor to selectively cover and uncover the torque coupling. The cover pivot shaft has a driven gear, and the torque coupling has a driving gear. When a U-axis head is disengaged from the torque coupling and machine spindle, the gears are held in mesh by a biasing spring applied to the torque coupling, and the cover may be rotated. When a U-axis head engages the torque coupling, the biasing spring is overcome and the gears are forced out of mesh; at this time, the servomotor may rotate the input tool member of the U-axis head to position its tool, while the cover remains stationary in the open position.
