  • Patent number: 5974650
    Abstract: In a workpiece assembling apparatus for assembling a torque converter to a transmission, a moving table and an inserting table are supported so as to approach and leave the transmission positioned. A suction pad for holding the torque converter is provided rotatably by a rotating shaft on the inserting table. The rotating shaft is rotated by a driving rotary unit to rotate the torque converter attracted and held by the suction pad to center it. Then, the torque converter is brought together with the inserting table close to the transmission, and pressed against it. Simultaneously, the torque converter is rotated about the axis of fitting. If the torque converter and the transmission are not fitted together, the torque converter is caused to reciprocate back and forth by the pusher cylinder 57 so that they will be fitted together.
