[0024] A protrusion 10 is provided at one end of the telescopic rod 5 away from the motor 4, and a groove 11 is provided at one end of each slide rod 6 away from the slot 8, and the protrusion 10 and the groove 11 are matched in shape to avoid shaking between the telescopic rod 5 and the slide rod 6 that affects the stability of the device.

[0025] Two groups of baffles 13 are rotatably arranged on the surface of the bracket 2 near the telescopic rod 5, a first torsion spring is arranged between the baffle 13 and the bracket 2, and two clamping strips 12 are fixedly installed on the surface of the swivel 3 near each sliding rod 6, the clamping strips 12 and the baffles 13 play an auxiliary positioning effect on the selected clamping block 9.

[0026] A plurality of piston cylinders 14 are fixedly installed on the surface of the swivel 3 near the slide rod 6, a piston plate 15 is sleeved in the piston cylinder 14, a connecting rod 16 is fixedly installed on the surface of the piston plate 15, the connecting rod 16 is fixedly connected to the slide rod 6, an air hole is opened on the surface of the piston plate 15, a baffle 17 is rotatably installed at the air hole, a second torsion spring is arranged between the baffle 17 and the piston plate 15, the baffle 17 rotates unidirectionally, and the piston cylinder 14 is arranged so that the slide rod 6 drives the clamping block 9 to slowly reset, thereby reducing the mechanical wear on the surface of the slide rod 6, avoiding collision with other parts to cause the clamping block 9 to shake, and providing stability of the device.

[0027] The bracket 2 is mounted on the surface of the support plate 1 by fixing screws. The support plate 1 can be directly used as a carrier for the workpiece, or the support plate 1 and the bracket 2 can be disassembled and reassembled on the workbench surface of the processing equipment for flexible application.

[0028] The cross-sectional diameter of the telescopic rod 5 matches that of the sliding rod 6 . The telescopic rod 5 moves under the control of the motor 4 and passes through the surface of the rotating ring 3 to push the sliding rod 6 to move.

[0029] The cross-sectional area of ​​the baffle 17 is slightly smaller than the area of ​​the air hole, and a small gap between the baffle 17 and the piston plate 15 allows air to pass slowly.

[0030] The support plate 1 is directly used as a carrier for processing the workpiece, or the support plate 1 is fixed to the bottom of the workbench of the processing equipment so that the clamping device corresponds to the processing area, and the workpiece to be processed is placed on the surface of the workbench. According to the shape and type of the workpiece, the rotating ring 3 is rotated to select the type of clamp block 9 to be used. The rotating ring 3 drives the slide bar 6 to rotate. When the slide bar 6 rotates, it drives the clamp block 9 in the slot 8 to rotate, so that the clamp block 9 to be used reaches the designated working area. At the same time, when the rotating ring 3 rotates, it drives the surface clamping strip 12 to rotate. After the clamping strip 12 contacts the baffle 13, it pushes the baffle 13 to rotate. When the clamping strip 12 completely passes through the baffle 13, the baffle 13 is in the first torsion spring. The resetting clamping strip 12 is rotated under the action of elastic force to keep the rotating swivel 3 stable. The baffle 13 limits the clamping strip 12 to assist the swivel 3 in completing the selection of the clamping block 9. When the swivel 3 stops rotating, the slide bar 6 corresponding to the clamping block 9 is aligned with the telescopic rod 5. The power supply is started to energize the device, and the control unit controls the motor 4 to operate. The operating motor 4 controls the telescopic rod 5 to move in the direction of the slide bar 6. The moving telescopic rod 5 makes the protrusion 10 on the surface enter the groove 11 on the surface of the slide bar 6 to complete the docking of the telescopic rod 5 and the slide bar 6. At the same time, the shape of the protrusion 10 on the surface of the telescopic rod 5 is consistent with the shape of the groove 11 on the surface of the slide bar 6, so as to avoid the telescopic rod 5 from contacting the slide bar 6. The moving telescopic rod 5 pushes the sliding rod 6 to move the sliding rod 6, and the moving sliding rod 6 pushes the clamping block 9 to move in the direction of the workpiece, so that the clamping block 9 clamps the workpiece, thereby avoiding the workpiece from shaking during processing and causing processing errors. After the processing is completed, the control unit controls the motor 4 to reset the telescopic rod 5. The reset telescopic rod 5 is no longer in contact with the sliding rod 6. The sliding rod 6 is reset under the elastic force of the reset spring 7, driving the clamping block 9 away from the workpiece, making it convenient for the staff to take out the processed workpiece. The sliding rod 6 will drive the connecting rod 16 to move during the resetting process, and the moving connecting rod 16 will be moved. The connecting rod 16 drives the piston plate 15 to slide in the piston cylinder 14, and the sliding piston plate 15 pushes the air inside the piston cylinder 14. Because there is a small gap between the baffle 17 on the surface of the piston plate 15 and the piston plate 15, the air in the piston cylinder 14 can slowly flow through the pores on the surface of the piston plate 15, so that the piston plate 15 slowly slides in the piston cylinder 14. The slowly sliding piston plate 15 drives the sliding rod 6 to slowly reset through the connecting rod 16, so as to avoid the sliding rod 6 from quickly resetting after the processing is completed and colliding violently with other parts to cause mechanical wear, and to avoid the clamping block 9 from shaking and falling off due to collision, thereby improving the installation stability of the clamping block 9 and extending the service life of the device.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
