[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please refer to Figures 1-11. This invention provides a technical solution for a polishing apparatus used in the processing of automotive rear covers:

[0032] As shown in Figures 1, 2, 3, 5, 6, 7, and 11, a polishing device for processing automobile rear covers includes a rear cover 1 to be polished and a device base 2. The device base 2 is equipped with a polishing mechanism having a polishing brush 305. A device bracket 301 is slidably connected to the device base 2. Multiple connecting shafts 309 are rotatably connected to both the transverse and longitudinal sections of the device bracket 301. A sleeve 314 is slidably inserted into the lower end of each connecting shaft 309, and a ball 31 is disposed inside the lower end of the sleeve 314. 8. The ball 318 and the sleeve 314 form a ball-and-socket assembly. A connecting shaft 315 is welded to the surface of the ball 318. The polishing brush 305 is fixedly connected to the lower end of the connecting shaft 315. The polishing brush 305 can be rotated to polish the back cover 1 to be polished. A support frame 307 is fixedly connected to the polishing brush 305. A sponge sleeve 308 is sleeved on the support frame 307. The sponge sleeve 308 can prevent the harder parts on the polishing brush 305 from contacting the back cover 1 to be polished during the movement and causing scratches.

[0033] Among them, a transmission wheel 324 is fixedly connected to the connecting shaft 309, a long transmission belt 321 is connected to multiple transmission wheels 324 in the transverse section of the device bracket 301, a short transmission belt 322 is connected to multiple transmission wheels 324 in the longitudinal section of the device bracket 301, a first drive motor 303 is fixedly installed in the transverse section of the device bracket 301, the output shaft of the first drive motor 303 is fixedly connected to one of the connecting shafts 309 in the transverse section of the device bracket 301, and a second drive motor 304 is fixedly installed in both longitudinal sections of the device bracket 301, the output shaft of the second drive motor 304 is fixedly connected to one of the connecting shafts 309 in the longitudinal section of the device bracket 301;

[0034] The device base 2 is equipped with a positioning mechanism that has abutment plates 509 and screws 510 cooperating. A suspension bracket 502 is welded on the device base 2. A positioning bracket 513 is fixedly connected to the suspension bracket 502. A second dual-output shaft motor 512 is fixedly installed on the positioning bracket 513. Two screws 510 are fixedly connected to the output shafts of the two second dual-output shaft motors 512 respectively. By rotating the screws 510, the abutment plates 509 can be driven to move. The threads of the two screws 510 are opposite. The two abutment plates 509 are respectively fitted with the two screws 510. The inner wall of the back cover 1 to be polished can be pressed against by the two abutment plates 509 to fix the back cover 1 to be polished. A guide rod 511 is fixedly connected to the positioning bracket 513. The two ends of the guide rod 511 are respectively inserted into the interior of the two abutment plates 509.

[0035] In practical use, the back cover 1 to be polished is placed on two abutment plates 509. Then, the two screws 510 are rotated by the second dual-output shaft motor 512. Since the threads of the two screws 510 are opposite, the rotation of the screws 510 can drive the two abutment plates 509 to move away from each other. The two abutment plates 509 abut against the inner wall of the back cover 1 to be polished, thereby fixing the back cover 1 to be polished. Then, the device bracket 301 drives multiple polishing brushes 305 to move, and the first drive motor 303 and the second drive motor 304 drive multiple sets of polishing brushes 305 at different positions to rotate. The rotating polishing brushes 305 can then polish the back cover 1 to be polished. During the polishing process, since the sleeve 314 and the connecting rod 310 are both movable structures, and the ball-and-socket assembly composed of the sleeve 314 and the ball 318 can allow the polishing brushes 305 to rotate in various directions, the polishing brushes 305 are always in contact with the surface of the back cover 1 to be polished during the polishing process.

[0036] As shown in Figures 9 and 10, corrugated strips 501 are fixedly connected to both sides of the device base 2. The corrugations on the two corrugated strips 501 are staggered. The polishing brush 305 can be swayed left and right by the corrugated strips 501 to reduce the polishing dead angle. The lower ends of the two longitudinal sections of the device bracket 301 are rotatably connected to the support shafts 323. A horizontal plate 504 is fixedly connected between the lower ends of the two longitudinal sections of the device bracket 301. The interior of both ends of the horizontal plate 504 is slidably connected to the sliders 507. A pull rope 506 is fixedly inserted inside the sliders 507. The two sides of the device base 2 are fixedly installed with the first dual-output shaft motor 505. The two output shafts of the first dual-output shaft motor 505 are fixedly connected to the rotating rods 503. The two ends of the rotating rods 503 are fixedly connected to the winding shafts 508. The pull rope 506 can be wound up by the winding shafts 508. The two ends of the pull rope 506 are fixedly connected to the corresponding two winding shafts respectively.

[0037] The device support 301 is fixedly connected to multiple connecting columns 311, which are grouped into groups of four. The lower end of each connecting column 311 is fixedly connected to a straightening spring 312. The straightening spring 312 can keep the polishing brush 305 in a vertical or horizontal state when it is not under force. A connecting frame 313 is sleeved on the connecting shaft 315, and the lower end of the straightening spring 312 is fixedly connected to the surface of the connecting frame 313.

[0038] In practical use, the first dual-output shaft motor 505 can drive the winding shaft 508 to wind the pull rope 506, thereby pulling the horizontal plate 504 and the polishing brush 305 on the device bracket 301 to move, so as to polish the back cover 1 to be polished. At the same time, since the two corrugated strips 501 are staggered, when the device bracket 301 moves, the device bracket 301 and the polishing brush 305 can be guided by the corrugated strips 501 to sway left and right, thereby reducing the polishing dead angles in the polishing process.

[0039] As shown in Figures 3, 4 and 8, a waxing mechanism is provided on the device support 301. The waxing mechanism includes a connecting pipe 316, an input ring 319 and a delivery main pipe 302. Multiple delivery hoses 306 are connected to the delivery main pipe 302. Multiple connecting rods 310 are slidably inserted on the device support 301. The multiple connecting rods 310 are grouped into groups of four. The input ring 319 is fixedly connected to the connecting rods 310. An injection nozzle 317 is connected to the outer arc surface of the input ring 319. The delivery hoses 306 are connected to the injection nozzle 317.

[0040] The input ring 319 has a rotating ring 320 inside, and a connecting pipe 316 is fixedly connected to the rotating ring 320. The connecting pipe 316 is fixedly inserted into the polishing brush 305. A wax storage box 401 is fixedly installed on the device bracket 301. The main conveying pipe 302 is connected to the bottom of the wax storage box 401. An electric telescopic rod 403 is fixedly installed on the top of the wax storage box 401. A piston plate 404 is fixedly connected to the output end of the electric telescopic rod 403. The electric telescopic rod 403 can push the piston plate 404 to squeeze out the polishing wax. A wax replenishment pipe 402 is connected to the wax storage box 401. After the polishing wax in the wax storage box 401 is used up, polishing wax can be replenished into the wax storage box 401 through the wax replenishment pipe 402. The wax replenishment pipe 402 is equipped with a cap.

[0041] In practical use, before each polishing, the piston plate 404 can be pushed downward by the electric telescopic rod 403, so that the viscous polishing wax in the wax storage box 401 can be transported to the input ring 319 through the main delivery pipe 302 and the delivery hose 306, and then injected into the polishing cloth on the polishing brush 305 through the connecting pipe 316. This replenishes the polishing wax before polishing, so that the polishing brush 305 can be used to polish the cover 1 to be polished.

[0042] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
