[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 to Figure 5 The cylindrical piston ring clamping fixture with self-rotation function shown in the figure includes a frame 1. In order to improve the use function of the clamping fixture and achieve the effect of continuous production, a conveyor belt 4 is rotatably arranged on the frame 1. Both ends of the frame 1 are rotatably connected with rollers 2, and the conveyor belt 4 is sleeved between the two rollers 2. A motor 16 is fixedly connected to the outer wall of the frame 1, and one of the rollers 2 is fixedly connected to the driving shaft of the motor 16. When working, the motor 16 rotates to drive the roller 2 fixedly connected to its driving shaft to rotate, thereby realizing the rotation and transportation of the conveyor belt 4. When in use, the material can be loaded at one end of the frame 1, the coating operation can be carried out in the middle section, and the material can be unloaded at the other end, so that continuous production can be achieved.

[0024] In order to achieve the clamping of the cylindrical piston ring, a positioning tube 5 is passed through the conveyor belt 4, and the positioning tube 5 is rotatably connected to the conveyor belt 4. There are multiple positioning tubes 5, and the multiple positioning tubes 5 are evenly distributed around the conveyor belt 4. An airbag 6 is fixedly connected to one end of the positioning tube 5 located outside the conveyor belt 4, and the airbag 6 is connected to the positioning tube 5 through a square opening 7. There are multiple airbags 6, and the multiple airbags 6 are evenly distributed around the positioning tube 5. The cylindrical piston ring is plugged into the positioning tube 5. When the airbag 6 is inflated and expanded, it will adaptively abut against the inner wall of the cylindrical piston ring. The multiple airbags 6 cooperate to complete the clamping of the cylindrical piston ring.

[0025] The positioning tube 5 is fixedly connected with a tray 11 . When the cylindrical piston ring is inserted into the positioning tube 5 , its bottom end will abut against the tray 11 , thereby improving the stability of the clamping of the cylindrical piston ring.

[0026] In order to inflate the airbag 6, the frame 1 is provided with an air supply assembly that cooperates with the positioning tube 5, and the air supply assembly includes a square tube 13, a pump body 14 and a round port 15. The square tube 13 is fixedly connected to the inner wall of the frame 1, and the round port 15 is opened on the square tube 13. The round port 15 cooperates with the positioning tube 5, and the pump body 14 is fixedly connected to the outer wall of the frame 1, and the pump body 14 is connected to the square tube 13. When in use, the air supply assembly is the loading station, and the end away from the air supply assembly is the unloading station.

[0027] A solenoid valve 8 is fixedly mounted on the positioning tube 5 .

[0028] During operation, when one of the positioning tubes 5 corresponds to the position of the circular mouth 15, the solenoid valve 8 is opened to control the pump body 14 to start, and the pump body 14 inflates the air into the airbag 6 through the square tube 13, the positioning tube 5 and the square mouth 7. When the airbag 6 is inflated and expanded, it will adaptively abut against the inner wall of the cylindrical piston ring. Multiple airbags 6 cooperate to complete the clamping of the cylindrical piston ring.

[0029] Then the solenoid valve 8 is closed to keep the airbag 6 in an expanded state, which is convenient for subsequent coating operations. When the unloading station is reached, the solenoid valve 8 is opened to discharge the gas inside the airbag 6, which is convenient for removing the cylindrical piston ring.

[0030] The utility model arranges the positioning tube 5, the air bag 6 and the air supply assembly and other structures, and inserts the cylindrical piston ring into the positioning tube 5. When the air bag 6 is inflated and expanded, it will adaptively abut against the inner wall of the cylindrical piston ring. The multiple air bags 6 cooperate to complete the clamping of the cylindrical piston ring. The operation is simple and convenient, and the clamping efficiency is improved.

[0031] Considering that during the coating operation, in order to make the clamped cylindrical piston ring tool be uniformly coated, a support block 12 is fixedly connected to the inner wall of the frame 1, a rack 10 is fixedly connected to the support block 12, and a gear 9 is fixedly connected to one end of the positioning tube 5 located inside the conveyor belt 4, and the gear 9 is meshed with the rack 10. In specific use, the coating equipment is set at the rack 10 (not shown in the figure). When the conveyor belt 4 drives the positioning tube 5 to move, and it moves to the position corresponding to the rack 10, due to the meshing connection between the gear 9 and the rack 10, the gear 9 will drive the positioning tube 5 to rotate, and then the cylindrical piston ring tool will also rotate, so that the outer peripheral surface of the cylindrical piston ring tool can be uniformly coated.

[0032] The rack 10 is only arranged at this position so that it will not rotate during loading and unloading.

[0033] The utility model can clamp the cylindrical piston ring tool and simultaneously perform loading, coating and unloading by arranging structures such as a conveyor belt 4, a positioning tube 5, an air bag 6, a gear 9 and an air supply assembly, thereby realizing continuous processing.

[0034] When the conveyor belt 4 rotates, it will drive the positioning tube 5 and the gear 9 to rotate synchronously. Therefore, an annular groove 3 for the gear 9 to pass through is opened in the middle section of the roller 2 without affecting the normal rotation of the conveyor belt 4.
