[0072] In detail, when the automobile accessory 3 reaches the designated position, the telescopic assembly drives the second mounting seat 40 to move by being elongated through the driving cylinder 41, and the remaining sliding seats 36 are driven to move together through the two fixed rings 37; during the movement of the sliding seats 36, the long rod 38 starts to rotate and causes the first mounting seat 39 and the second mounting seat 40 to approach each other, thereby finally driving the grinding assembly and the paint spraying assembly to be attached to the automobile accessory 3; at this time, the first circular rod 46 and the second circular rod 51 are engaged with the corresponding clamping arms 57; then the rotating assembly, the paint spraying assembly and the grinding assembly are started respectively; in the grinding assembly, the polishing roller 45 is driven to rotate by the first servo motor 43 to polish the automobile accessory 3, and the debris generated by polishing is collected in the collecting box 48 through the hose 49 and the air extractor 47; the paint spraying assembly sprays the edges of the automobile accessory 3 through the plurality of spray heads 52; during the process, the rotating assembly drives the half gear 59 to rotate through the second servo motor 64, then drives the gear ring 58 engaged with the half gear 59 to rotate, the gear ring 58 in turn drives the plurality of clamping arms 57 through the mounting disc 56, and finally drives the grinding assembly and the paint spraying assembly to rotate synchronously to process a certain area; when the half gear 59 rotates to the empty part, the grinding assembly and the paint spraying assembly are reset due to the elastic force of the reset spring 63 in the elastic member 61; after the first part of the area is completed, the telescopic assembly is reset by the driving cylinder 41, then the automobile accessory 3 is rotated by a certain angle by the rotating motor 21, and the above working process is repeated again.

[0073] It should be noted that the edges of the automobile accessory 3 are alternately composed of the polishing part and the paint spraying part.

[0074] Working steps

[0075] When polishing the automobile parts 3 in batches, the driving motor 7 is controlled to operate, so that the driving pulley 8 drives the driven pulley 9 to rotate through the transmission belt 10, and then the transmission roller 5 drives the conveying belt 2 to rotate synchronously, and cooperates with the intermittent operation of the operating assembly to realize intermittent rotation. When the automobile parts 3 on the conveying belt 2 are operated to the position matched with the irregular guide hole 18, the operating motor 14 is operated to drive the rotating block 15 at the output end to rotate, and then through the connection of the connecting bolt 17 and the irregular guide hole 18 and the guide effect of the guide block 19, the operating rod 20 is rotated to the vertical state, and the triangular chuck 23 is coaxial with the clamping end of the automobile parts 3 on the conveying belt 2, so that the automobile parts 3 are clamped by the triangular chuck 23. Then, the operating motor 14 is reversely operated to drive the operating rod 20 to the horizontal state. The distance between the outer wall of the automobile parts 3 at the corresponding position and the infrared distance meter 33 is recognized by the infrared distance meter 33, and the distance information is sent to the controller 11. The distance data is converted by the controller 11 to control the extension cylinder 25 to operate, so that the extension end drives the U-shaped frame 24 to move until the cylindrical grinding tool 27 contacts with the outer wall of the automobile parts 3, so that the polishing motor 28 is controlled to operate, so that the driving gear 29 drives the driven gear 30 to rotate, so that the polishing shaft 26 drives the cylindrical grinding tool 27 to rotate synchronously, and the outer wall of the automobile parts 3 is polished, and the triangular chuck 23 is continuously rotated by the subsequent rotating motor 21, and the infrared distance meter 33 is used to control the extension cylinder 25 to keep operating, so that the cylindrical grinding tool 27 keeps contacting with the outer wall of the automobile parts 3, and the outer wall of the automobile parts 3 is fully polished. Compared with the existing manual polishing technology, the polishing efficiency of the aluminum material in batch production of automobile parts is improved.

[0076] The horizontal guide rod 31 is arranged to make the extension cylinder 25 operate to drive the U-shaped frame 24 to move horizontally and reciprocally more stably. The connecting mode of the bolt 32 is arranged to facilitate disassembly and assembly of the cylindrical grinding tool 27, regular replacement of the worn cylindrical grinding tool 27, and ensures the polishing effect of the aluminum material of the automobile parts.

[0077] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
