Abstract:
1. A part supplying and press-fitting apparatus for supplying an annular part to a predetermined position and press-fitting the part into a press-fit hole of a work in a state of being positioned in a circumferential direction, the positioning being performed by detecting a detected portion formed in the part; the apparatus comprising: a grip device configured to grip the part; an arm device having an arm portion configured to receive and grip the part supplied from a part feeder side, reversing the part by 180° around a shaft of a horizontal direction, and to hand the part to the grip device; a rotation device configured to rotate the grip device around a hole axis of the part in a state of having gripped the part; a detection device configured to detect the detected portion of the part being rotated by the rotation device; a stop device configured to stop the rotation of the grip device when the detected portion is detected; a move device configured to move the grip device stopped by the stop device to the predetermined position; and a press-fit head configured to descend to the predetermined position and press-fit the part into a press-fit hole of the work, wherein the grip device consists of a chuck device configured to place the part on a placement table face, to make a hole direction perpendicular to the placement table face, and to grip an outer peripheral face of the part, wherein the grip device is adapted to continuously grip the part during rotation of the grip device, during detection of the detected portion, and during movement of the grip device to the predetermined position, thereby preventing positional displacement of the part, and enabling the part to be properly press-fitted into the press-fitting hole, wherein the detected portion consists of a cutout formed at a rim of the part, and wherein the detection device freely ascends and descends, is contacted with a pressure to the rim in descent, and comprises a detection member that engages with the cutout.
