[0024] The sliding connecting plate 8 is a U-shaped plate structure, which is horizontally arranged with its opening facing forward.

[0026] Working principle:
[0027] The flange shaft 1 is connected to the external manipulator, and the telescopic cylinder 3 is retracted to pull the V-shaped push plate 5 to move backward along the linear guide rail A4. Since the linear guide rail B6 limits the movement of the clamping unit 7 and the sliding connecting plate 8 along the width direction of the support frame 2, and the rolling element 81 and the guide inclined surface 82 on the sliding connecting plate 8 are respectively fitted with the front inclined surface and the rear inclined surface of the inclined plate 51 on both sides of the V-shaped push plate 5, the V-shaped push plate 5 moves backward while pulling the sliding connecting plate 8 and the clamp arm 71 along the straight line. The slide rails B6 move away from each other, so that the clamping jaws 72 open, and the clamping device moves to the clamping position with the manipulator. The telescopic cylinder 3 is extended to push the V-shaped push plate 5 to move forward along the linear slide rail A4, so that the clamping plates 721 on the clamping jaws 72 are close to each other to clamp the disc-like parts. The clamping plates 721 are made of copper pads to prevent damage to the contact position of the workpiece during clamping, and the end faces of the disc-like parts are limited and supported by the clamping plates 722 on the clamping jaws 72. The clamping device transports the disc-like parts as the manipulator moves.

The clamping device can clamp disc-like parts of different diameters, and the clamping claws 72 have a large moving stroke, a large clamping range, and a fast clamping or releasing response speed; the sliding connecting plate 8 is half wrapped on the inclined plate 51 of the V-shaped push plate 5, and the top plate and the bottom plate at the open end of the sliding connecting plate 8 are provided with rolling parts 81 that fit the front end inclined surface of the inclined plate 51, with high clamping strength and good clamping action stability.
