[0053] On the basis of the above embodiment, the functions or effects of the technical features involved in the application, the working mode of the application are further described and explained, so that the skilled in the art can fully understand the technical scheme of the application and reproduce it.

[0054] In the application, the first step of the equalizing ring processing process should be to lay out the drawing and obtain an aluminum pipe of appropriate length. When cutting, a processing allowance should be left to meet the subsequent processing requirements. At the same time, when bending in the second step, the bending operation should be strictly in accordance with the operating instructions of the bending machine to avoid obvious defects in the aluminum pipe during the bending process and improve the success rate of the aluminum pipe bending to facilitate the next operation. The processing of the equalizing ring support rod should be in accordance with the requirements of the third step, such as flattening the end of the support rod, drilling, modifying the profile, and edges of the end to facilitate the welding or connection of the aluminum pipe welded into a ring in the subsequent operation. The operation of welding the aluminum pipe into a ring adopts argon arc welding, the welding wire diameter is 4.6 mm, and the material is 5056. During the operation of welding the aluminum pipe into a shape, the aluminum pipe should be fixed on a clamp, the inclination angle of the clamp should be large to facilitate the removal of excess edges at the end of the cut pipe, facilitate welding, ensure the welding quality, and the welding position should have a uniform scale ripple surface without defects such as cracks, craters, burn-through, and intermittent welds. After the ring body is welded, it should be polished smooth, and during transportation, avoid scratches and scratches on the smooth surface of the ring body, after inspection, install the bolt assembly and wrap and package for storage.

[0055] When using the ring seam polishing device, the operator sets the equalizing ring 7 on the rack 1, the rack 1 is located inside the equalizing ring 7, the bottom of the equalizing ring 7 is located in the pressure ring placing groove 28, and the limiting plug-in block 29 after plug-in is limited in the pressure ring placing groove 28. The middle position of the equalizing ring 7 is lapped on the pressure ring lapping plate 39, at this time the equalizing ring 7 is in the state of the ring seam position to be polished and the polisher 18 not aligned.

[0056] The bidirectional driver 22 starts to work, the two telescopic ends of the bidirectional driver 22 drive the telescopic shaft 36 to realize the movement of the pressure ring positioning block 8 away from the main shaft swing plate 37 through the telescopic shaft connection sleeve 38, and then realize the alignment of the ring seam position to be polished and the polisher 18 through the movement of the pressure ring positioning block 8.

[0057] After the adjustment is completed, the moving plate main driver 12 and / or the moving plate auxiliary driver 30 start to work, so that the moving plate 4 moves along the rack slide rail 3 through the sliding block, and after the moving plate 4 moves relative to the rack 1, it can drive the equalizing ring 7 to move in the direction of the polisher 18, and the polisher 18 polishes the ring seam position.

[0058] During the polishing process, the moving plate main driver 12 and the moving plate auxiliary driver 30 can realize the reciprocating movement of the moving plate 4 and the equalizing ring 7, and then the polisher 18 can improve the polishing quality when polishing the ring seam of the equalizing ring 7.

The movement of the polishing active plate 9 relative to the mobile plate 4 can realize that the pressure ring 7 rotates a certain angle around the central axis of the active shaft 23 under the action of the pressure ring positioning block 8. The above action process is realized by the meshing transmission of the U-shaped driving plate 21 and the gear teeth at the middle position of the active shaft 23. The active shaft 23 can cooperate with the main shaft seat 24 to realize the rotation around the central axis thereof under the meshing rotation. In the above action process, the auxiliary plate lifter 25 at the bottom of the polishing auxiliary plate 6 drives the bottom placing plate 27 to move downward, and the polishing auxiliary plate 6 follows the swing of the pressure ring 7 to realize the following sliding along the mobile plate slide rail 5.

[0061] After the angle adjustment of the pressure ring 7 is completed, the execution structures no longer act, the positions of the polishing active plate 9 and the polishing auxiliary plate 6 relative to the mobile plate 4 are fixed, and the mobile plate 4 is again close to the position of the polisher 18 under the action of the mobile plate main driver 12 and / or the mobile plate auxiliary driver 30. At this time, the polisher 18 should be under the action of the polishing lifting driver 14, so that the relative position of the polishing top plate 17 and the polishing bottom plate 13 is raised, and the polishing inlet of the polisher 18 can be consistent with the adjusted pressure ring 7.

[0062] The polisher 18 described in the present application includes an upper polishing belt assembly 31 and a lower polishing belt assembly 32. The relative positions of the upper polishing belt assembly 31 and the lower polishing belt assembly 32 are adjustable through the polishing lifter 35, the polishing lifting guide seat 33 and the polishing lifting guide shaft 34, thereby realizing cooperation and polishing with different models (diameters) of pressure rings 7.

[0063] The cooperation structure of the fine adjustment motor 19, the box body telescopic plate 20 and the U-shaped driving plate 21 can realize fine adjustment and compensation of the rotation angle of the active shaft 23.

[0064] The sliding groove machined on the telescopic shaft 36 and the sliding block structure machined in the through hole through which the telescopic shaft 36 passes in the main shaft swing plate 37 are used to realize that the telescopic shaft 36 moves along the central axis thereof without rotating circumferentially, and then stably moves outward under the action of the bidirectional driver 22, so as to realize synchronous clamping of the pressure ring 7 by the pressure ring positioning block 8.

[0065] Finally, although the present specification is described in terms of embodiments, not every embodiment exhibits every characteristic or implements every combination of features described in the present specification. The present specification has been described in a manner that is thorough and complete to one skilled in the art and the specification is intended to be construed as an exemplification of one or more embodiments rather than as an exhaustive list of embodiments.
