ABSTRACT:
An apparatus for operatively coupling a rotatably driven machine tool accessory, such as a right angle milling head, to a machine tool having a rotary output shaft, such as a horizontal boring machine. The apparatus includes a first collar that is mounted to the horizontal boring machine in a position that is adjacent to the rotary output shaft thereof. A second collar is mounted to the machine tool accessory and is adapted to mate with the first collar. Cylinder actuated ball locking devices are provided in the second collar and are adapted to be received in corresponding receptacles in the first collar. The cylinders are adapted to cause the ball locking devices to engage the receptacles in the first collar to thereby secure the first collar to the second collar. To disengage the second collar from the first collar, the cylinders are retracted to permit the ball lock devices to disengage the receptacles in the first collar. A drive member, adapted to be received in a spindle member mounted to the output shaft of the horizontal boring machine, is provided to positively engage the rotary driven element of the machine tool accessory. A cradle is provided to support the machine tool accessory in a known position remote from the spindle on the horizontal boring machine. A cylinder actuated enclosure is pivotally fastened to the cradle to protect the machine tool accessory when not in use.
