[0019] The upper end of the workbench 1 is rotatably connected with a gear ring 2, and the upper end of the gear ring 2 is evenly distributed and fixedly connected with three support plates 6. A guide rail 9 is provided on the surface of the support plate 6, and the support plate 6 can be divided into multiple parts by the guide rail 9. The height of the fixing ring 3 is conveniently fixed by the support plate 6 and the guide rail 9. The support plate 6 is in an inverted M shape as a whole, and can be more closely contacted with the support plate 6 through the connecting block 14. The gear ring 2 is meshed and connected with the gear 24. When the motor 7 drives the gear 24 to start rotating, the gear ring 2 will also rotate under the meshing action. The upper end of the support plate 6 is detachably installed with a fixed cover 5. The fixing cover 5 can limit the fixing ring 3 to prevent the fixing ring 3 from falling out. The upper end of the gear ring 2 is in contact with a plurality of fixing rings 3. The number of fixing rings 3 can be determined according to the welding conditions of the bellows valve. If there are more welding slag and other impurities, the number of fixing rings 3 can be increased. The surface of the fixing ring 3 is provided with a sliding groove 23. The inner wall of the sliding groove 23 is in contact with the support plate 6. A plurality of fixing rings 3 are sleeved on the surface of the support plate 6 through the sliding groove 23. The fixing ring 3 is slidably connected to the guide rail 9. At this time, the height and position of the fixing ring 3 can be changed by moving up and down.

[0020] A plurality of sweeping brush heads 4 are detachably mounted on the inner side of the fixing ring 3. The sweeping brush heads 4 can be divided into multiple types. Sweeping brush heads 4 of different lengths can be adapted according to the shape and size of the bellows valve to be cleaned. Sweeping brush heads 4 of different hardness and softness can be replaced according to the type of welding residue of the bellows valve, so that the sweeping brush head 4 as a whole can effectively and meticulously clean the bellows valve. A threaded rod 13 is threadedly connected to one side of the fixing ring 3, and a connecting block 14 is slidably connected to the inner wall of the fixing ring 3. By controlling the sliding of the connecting block 14, the fixing ring 3 can be fixed in a fixed state on the support plate 6. The line changes, the surface of the connecting block 14 contacts the surface of the support plate 6, one end of the threaded rod 13 passes through the surface of the fixing ring 3 and is rotatably connected to the connecting block 14, the threaded rod 13 does not contact the support plate 6, the threaded rod 13 is threadedly connected to the fixing ring 3, and when the fixing ring 3 is slid to the specified position of the guide rail 9, the threaded rod 13 begins to be rotated, and the connecting block 14 will gradually move toward the support plate 6. After the two are in contact, the threaded rod 13 continues to be rotated, and the surface of the connecting block 14 will squeeze the surface of the support plate 6, and then the fixing ring 3 can be fixed at a specified height on the support plate 6.

[0021] The upper end of the workbench 1 is fixedly connected to the vertical plate 10, and the inner ring surface of the workbench 1 is fixedly connected to the fixed tube 19, which can limit the slider 17. The upper end of the vertical plate 10 is rotatably connected to the rotating plate 11, and the surface of the vertical plate 10 contacts the rotating frame 22, and the other end of the rotating frame 22 is rotatably connected to the side of the rotating plate 11. At this time, due to the obstruction of the rotating frame 22, the position of the rotating plate 11 is locked and cannot be rotated. When the rotating frame 22 is rotated so that it does not contact the vertical plate 10, the rotating plate 11 is unlocked and can start to rotate. The other end of the rotating plate 11 is connected to the slider 17. A sliding groove 15 is provided on the upper surface of 17, and a fixed groove 18 is provided at the lower end thereof. The sliding groove 15 and the fixed groove 18 are connected to each other, so that it is convenient to slide the slider 17 upward to complete the disassembly of the slider 17, and then replace or clean the sweeping brush head 2 12. The rotating plate 11 is slidably connected with the slider 17 through the sliding groove 15. The hardness of the sweeping brush head 2 12 should be softer than that of the sweeping brush head 14, so that the residue on the sweeping brush head 4 can be better cleaned. The inner wall of the fixed groove 18 contacts the fixed tube 19, so that the slider 17 can be limited to avoid shaking at its lower end that affects the cleaning effect.

[0022] A sliding groove 15 is provided on the surface of the sweeping brush head 12, and the sliding sweeping brush head 12 can avoid obstruction to the upward sliding fixed ring 3. The rotating plate 11 is slidably connected with the sweeping brush head 12 through the sliding groove 15. One side of the sweeping brush head 12 contacts the inner ring surface of the fixed ring 3. When the gear ring 2 rotates, the fixed ring 3 will also rotate under the action of the supporting plate 6. At this time, the sweeping brush head 14 will continuously sweep the bellows valve when it passes the bellows valve, so that the dirt and welding slag on the surface of the bellows valve will fall off. The cleaned sweeping brush head 4 will continue to rotate and pass through the sweeping brush head 12. At this time, the sweeping brush head 12 will clean the residual welding slag on the surface of the sweeping brush head 4 to prevent the sweeping brush head 4 from continuing to bring the residue into the surface of the bellows valve.

[0023] The upper end of the slider 17 is rotatably connected to a hook-shaped piece 21, and the groove at the other end of the hook-shaped piece 21 contacts the surface of the limit column 20. The upper end of the limit column 20 is fixedly connected to the limit plate. At this time, the hook-shaped piece 21 is fixed in the vertical direction, and the lower end of the limit column 20 is fixedly connected to one side of the rotating plate 11, so as to limit the upper and lower directions of the slider 17. The position of the mounting tube 16 is in the inner ring of the workbench 1, and the side of the mounting tube 16 is close to the sweeping brush head 4, so as to facilitate the sweeping brush head 4 to clean the surface of the bellows valve, and it is also beneficial for the welding slag cleaned from the parts to be discharged into the collecting plate 25.

[0024] When the device is working, after checking that the device is correct, install the bellows valve in the installation tube 16. The surface of the installation tube 16 should be close to the inner wall of the inner ring surface of the workbench 1. Then install different sweeping heads 4 on several fixing rings 3 according to the welding slag and other dirt on the surface of the bellows valve. After the installation is completed, insert the fixing ring 3 into the support plate 6. During this process, the fixing ring 3 equipped with the corresponding sweeping head 4 is slid along the guide rail 9 to a suitable height and then stop sliding. Then rotate the threaded rod 13 on the surface of the fixing ring 3. During this process, the surface of the connecting block 14 and the fixing ring 3 will gradually increase the pressure on the support plate 6, so that the two can clamp the support plate 6, so that the fixing ring 3 is fixed at a specified height of the support plate 6. Then install the fixing cover 5. After completion, select a suitable sweeping brush head 12 and install it on the surface of the slider 17, slide the slider 17 to make the fixed groove 18 contact with the fixed tube 19, then rotate the hook-shaped piece 21 to make it contact with the limit column 20, and then rotate the rotating frame 22. At this time, the position of the slider 17 is locked and will not shake. Start the motor 17 and the motor 2 8. The sweeping brush heads 14 at different positions will continue to sweep and clean the welding slag at different positions on the surface of the bellows valve. The sweeping brush head 12 will clean the residue on the surface of the sweeping brush head 4, and the cleaned residue will enter the collecting plate 25, thereby completing the cleaning of the bellows valve. In the cleaning process, different sweeping brush heads 4 will clean the surface of the bellows valve to different degrees, effectively avoiding damage to its surface.
