[0022] The movable plate 3 has a slide rail 31 on its side, and a mounting plate 32 is slidably connected to the slide rail 31. A clamping assembly is provided on the mounting plate 32. A cylinder 311 is provided on the side wall of the movable plate 3. The output end of the cylinder 311 is fixedly connected to the mounting plate 32. The cylinder 311 is electrically connected to the controller. The controller controls the motor 22 to rotate and move the clamping assembly to one end. It controls the cylinder 311 to extend. At this time, the clamping assembly clamps the workpiece. The cylinder 311 retracts, and the motor 22 reverses to move the clamping assembly to the other end, thereby completing the task of moving the workpiece from one place to another. The clamping assembly includes a gear 33 rotatably connected to the side wall of the mounting plate 32 and a connecting frame 333 fixedly connected to the bottom of the mounting plate 32. There are two gears 33 meshing with each other. A first connecting rod 331 is provided on the outer end face of the gear 33. A second connecting rod 332 is provided on the side end of the first connecting rod 331 and is rotatably connected to one end of the second connecting rod 332.

The other end of the second connecting rod 332 is rotatably connected to the rotating frame 334. A clamping block 335 is movably connected to the rotating frame 334. A rotating shaft 336 is fixedly connected to the rotating frame 334. A rotating block 3351 is provided on the side wall of the clamping block 335. The rotating block 3351 is rotatably connected to the rotating shaft 336. A torsion spring 3361 is sleeved on the rotating shaft 336. The movable end of the torsion spring 3361 is connected to the rotating block 3351.

The rack 322 is meshed with the gear 33.

[0023] The controller controls the extension of the second cylinder 321, which drives the first connecting rod 331 and the second connecting rod 332 to rotate, thereby driving the rotating frame 334 to clamp the workpiece. Since the clamping block 335 can rotate, both arc-shaped clamping blocks 337 abut against the side wall of the workpiece, thereby achieving multi-point clamping and stable clamping.

[0024] Working principle: The controller controls the motor 22 to rotate and move the clamping assembly to one end. The controller controls the second cylinder 321 to extend, which can drive the first connecting rod 331 and the second connecting rod 332 to rotate, thereby driving the rotating frame 334 to clamp the workpiece. Since the clamping block 335 can rotate, both arc-shaped clamping blocks 337 are in contact with the side wall of the workpiece. After clamping is completed, the workpiece is moved to the other end, and the workpiece handling is completed.

[0025] Since the clamping block 335 can rotate, both arc-shaped clamping blocks 337 abut against the side wall of the workpiece, which can realize multi-point clamping of the workpiece, improve the stability of workpiece clamping, and since the clamping block can rotate, the clamping point can be adjusted, which is suitable for a variety of irregularly shaped workpieces and has wide applicability.
