Abstract
PURPOSE: To provide the subject device wherein a slide block which is in rack engagement with the claw of a chuck and opens or closes the claw is moved back and slided, the engagement between the slide block and the claw is released, whereby the claw of the chuck can be automatically replaced by the claw stored in the magazine.
CONSTITUTION: A magazine is turned and indexed during the cutting operation, and a claw to be used next is located at a stand-by position. After the completion of the cutting operation, the entire part of an exchanging arm part 9 is moved forward together with the magazine by the operations of a cylinder 17 and a piston 16. Then, a driver 51 is advanced by the operation of a cylinder 53, and the driver 51 is rotated by means of a motor 52 to release the rack engagement between the slide block 15 of the chuck and the claw 2. By the operation of the rotary cylinder 19 in this state, the claw exchanging arm is extended, and claws of the magazine and the chuck are held by a gripper 34. Then, the exchanging arm part 9 is rotated 180° by the inverse operation, and the arm is extended by the operation of the rotary cylinder 19, new and old claws are inserted into the magazine and chuck, and exchanged.
