When the workpiece needs to be clamped, the electric cylinder 32 is started, and the electric cylinder 32 pushes the telescopic rod 33 to extend outward. The telescopic rod 33 drives the small block 37 to move outward, and the small block 37 pushes the movable rod 38 to rotate around the fixed column 35. Since the movable rod 38 is connected to the connecting rod 39 through the cylinder 313 and the small rod 314, the rotation of the movable rod 38 will pull the connecting rod 39 to rotate around the small column 36. The rotation of the connecting rod 39 will drive the short block 311 to move, and the short block 311 drives the clamping block 312 to clamp the workpiece placed on the workbench 1. Through the telescopic movement of the output end of the electric cylinder 32, the clamping force and position of the clamping block 312 can be precisely controlled to meet the clamping requirements of workpieces of different sizes.

[0026] In one embodiment of the present utility model, a flip mechanism 4 is provided on the surface of the workbench 1, a fixed block 41 is fixedly installed on the surface of the workbench 1, a motor 42 is fixedly installed in the fixed block 41, a threaded rod 43 is fixedly connected to the output end of the motor 42, a moving block 44 is movably installed on the surface of the threaded rod 43, a slide rail 45 is fixedly installed on the surface of the workbench 1, a long block 46 is fixedly installed on the surface of the moving block 44, a sliding column 47 is fixedly installed on the side surface of the long block 46, a connecting rod 48 is slidably connected to the surface of the sliding column 47, a supporting block 49 is fixedly installed on the surface of the workbench 1, a rotating rod 411 is movably installed in the supporting block 49, the motor 42 is started, and the motor 42 is driven The movable threaded rod 43 rotates, and the moving block 44 is movably installed with the surface of the threaded rod 43. When the threaded rod 43 rotates, the moving block 44 will move linearly along the threaded rod 43. The movement of the moving block 44 drives the long block 46 to move synchronously. The slide column 47 on the long block 46 slides stably along the slide rail 45 to ensure the smoothness of the movement. The movement of the slide column 47 transmits force to the rotating rod 411 through the connecting rod 48, so that the rotating rod 411 rotates around the axis in the support block 49, thereby realizing the flipping action of the workpiece placed on the rotating rod 411. Through the forward and reverse control of the motor 42, the workpiece can be flipped at different angles, which is convenient for multi-faceted processing of the workpiece or adjustment of the processing posture.

[0027] Working principle: When it is necessary to clamp the workpiece, the electric cylinder 32 is started, and the electric cylinder 32 pushes the telescopic rod 33 to extend outward, and the telescopic rod 33 drives the small block 37 to move outward, and the small block 37 pushes the movable rod 38 to rotate around the fixed column 35. Since the movable rod 38 is connected to the connecting rod 39 through the cylinder 313 and the small rod 314, the rotation of the movable rod 38 will pull the connecting rod 39 to rotate around the small column 36, and the rotation of the connecting rod 39 will drive the short block 311 to move, and the short block 311 drives the clamping block 312 to clamp the workpiece placed on the workbench 1. Through the telescopic movement of the output end of the electric cylinder 32, the clamping force and position of the clamping block 312 can be accurately controlled to meet the clamping requirements of workpieces of different sizes. A rubber block is installed on the clamping block 312. In order to increase the stable clamping of the object, the motor 42 is started, and the motor 42 drives the threaded rod 43 to rotate. Since the moving block 44 is movably installed on the surface of the threaded rod 43, when the threaded rod 43 rotates, the moving block 44 will move linearly along the threaded rod 43. The movement of the moving block 44 drives the long block 46 to move synchronously. The sliding column 47 on the long block 46 slides stably along the slide rail 45 to ensure the smooth movement. The movement of the sliding column 47 transmits force to the rotating rod 411 through the connecting rod 48, so that the rotating rod 411 rotates around the axis in the support block 49, thereby realizing the flipping action of the workpiece placed on the rotating rod 411. By controlling the forward and reverse rotation of the motor 42, the workpiece can be flipped at different angles, which is convenient for multi-faceted processing of the workpiece or adjustment of the processing posture.
