摘要：A gripper device particularly suitable for positioning an annular member onto aworkpiece that includes a housing having a pair of piston chambers, each of the pistonchambers having a piston reciprocally mounted therein. A cover plate, having a pluralityof radial slides mounted therein for radial movement, is connected to the housing. A
plurality of through holes are also formed in the cover plate. One of the pistons has apiston rod to which each of the radial slides is connected thereto by an interconnectinglink. The other piston is provided with a pusher disposed in alignment with each of thethrough holes to extend therethrough in the operative position. The piston actuating theslides is fluid actuated between operative and inoperative positions and the pusherpiston is fluid actuated toward operative position and spring biased toward inoperativeposition. A gripping finger is adjustably positioned on each of the slides for handlingannular members of different sizes.
