Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts production, and particularly to a polishing device for automotive roof racks. Background Art

[0002] Automotive roof rack polishing refers to the polishing treatment of the surface of automotive roof racks to restore their original luster and protect the surface. Since automotive roof racks are often exposed to the external environment, after long-term use, problems such as fine scratches, oxidation, and stains are likely to appear on the surface, affecting the appearance and durability. Through the polishing process, surface defects and dirt can be removed, making the surface of the automotive roof rack smooth and shiny, achieving the effects of protection and beautification;

[0003] Traditional automotive roof rack polishing requires manual application of an appropriate amount of polishing wax or polishing agent on the surface of the automotive roof rack, and then evenly applying and polishing with a polishing cloth or polishing pad. During the production and transportation process of automotive roof racks, solid particle impurities such as dust and sand grains may adhere to the surface. These solid particle impurities may rub against the polishing pad or polishing cloth during the polishing process, resulting in scratches or abrasions on the surface of the automotive roof rack, thereby damaging the surface finish and aesthetics, and further causing wear on the surface of the roof rack, shortening the service life of the automotive roof rack. Secondly, manual polishing and grinding are inefficient and not suitable for mass production. Manual polishing and grinding require certain professional technical requirements for operators. Improper manual operation will result in uneven grinding, and uneven grinding will cause inconsistent gloss on the surface, affecting the overall aesthetics of the automotive roof rack. To address the above problems, the inventor proposes a polishing device for automotive roof racks to solve the above problems. Summary of the Invention

[0016] 1. By arranging a cleaning device for the surface of the luggage rack, the surface of the automobile luggage rack is cleaned of particulate impurities under the action of the cleaning device for the surface of the luggage rack. By arranging a reciprocating synchronous swing assembly, the automobile luggage rack swings slightly under the action of the reciprocating synchronous swing assembly.

By adjusting the positions of the moving guide roller and the lifting guide roller, the cleaning synchronous belt wraps around the surface of the vehicle luggage rack and is always in a taut state. The driving roller drives the cleaning synchronous belt to rotate to clean the impurities on the surface of the vehicle luggage rack. After cleaning, the cleaning synchronous belt rotates into the cleaning frame, and the cleaning liquid sprayed by the spray head is used to clean the cleaning synchronous belt, avoiding the possibility that solid particle impurities may scratch the vehicle luggage rack during the polishing process by rubbing against the polishing pad, resulting in scratches on the surface of the vehicle luggage rack and affecting the surface finish and aesthetics.

[0018] 3. The present invention provides a reciprocating synchronous swing assembly, which drives the vehicle luggage rack to swing slightly during the cleaning and polishing processes. The slight swing of the vehicle luggage rack increases the contact area between the vehicle luggage rack and the cleaning synchronous belt and the polishing assembly, improves the uniformity of cleaning and polishing, and ensures the surface finish and consistency of the vehicle luggage rack.

[0054] Working principle: First, place the car roof rack to be polished on the positioning rod 905, control the second electric cylinder 804 to start, and the driving end of the second electric cylinder 804 extends to push the moving frame 801 to move under the guidance of the guiding frame 802 and the slider 803. The moving frame 801 drives the corresponding positioning rod 905 to move synchronously. The positioning rods 905 on the moving frame 801 and the positioning rods 905 on the fixed frame 7 move away from each other to clamp and fix the inner side of the car roof rack. Control the left lifting device 4 to start, and the left lifting device 4 drives the cleaning frame 501 to descend. After the cleaning synchronous belt 520 contacts the upper surface of the car roof rack, it continues to move downward a certain distance. At this time, synchronously control the first electric cylinder 515 to start, and the driving end of the first electric cylinder 515 extends to push the connecting plate 514 downward. The connecting plate 514 drives the lifting block 503 to move downward under the guidance of the guiding fixed frame 502. The descent of the lifting block 503 drives the connecting block 504 and the connecting fixed frame 511 to descend synchronously. The connecting fixed frame 511 drives the five lifting guide rollers 513 to descend synchronously through the bracket 512 to contact the cleaning synchronous belt 520 and descend to be flush with the fixed guide roller 519. During the descent of the connecting block 504, the flipping frame 506 is driven by the driving rod 505 to flip towards the connecting fixed frame 511 with the flipping frame 506 and the guiding fixed frame 502 as the axis. The flipping of the flipping frame 506 drives the two moving guide frames 508 to approach each other under the guidance of the guide rail 507. The approaching of the moving guide frames 508 drives the moving guide rollers 510 to move synchronously. Through the movement adjustment of the moving guide rollers 510 and the lifting guide rollers 513, the outer side of the cleaning synchronous belt 520 wraps the top of the car roof rack and is always in a tight state. Control the first motor 517 to start, and the driving end of the first motor 517 drives the left driving roller 516 to rotate counterclockwise through the synchronous pulley transmission group. The left driving roller 516 drives the right driving roller 516 to rotate synchronously through the synchronous pulley transmission group. The rotation of the driving roller 516 drives the cleaning synchronous belt 520 to rotate counterclockwise. The rotation of the cleaning synchronous belt 520 contacts the car roof rack to clean the surface of the car roof rack. After cleaning, the cleaning synchronous belt 520 rotates into the cleaning frame 521. Control the pressure water pump 527 to start, and the pressure water pump 527 transports the cleaning liquid in the water tank 526 to the fixed pipe 524 through the delivery pipe 528 and sprays it on the outer side of the cleaning synchronous belt 520 through the nozzle 525 to clean the cleaning synchronous belt 520. After cleaning, the cleaning synchronous belt 520 rotates to the scraper 523, and the two scrapers 523 scrape off the moisture on the outer side of the cleaning synchronous belt 520. The scraped cleaning liquid falls into the cleaning frame 521 and is discharged through the drain pipe 529 to the drain channel 530 and discharged under the guidance of the drain channel 530. Under the slow movement of the top moving device 3, the surface of the car roof rack is cleaned, and the right lifting device 4 drives the polishing assembly 6 to contact the surface of the car roof rack to polish the cleaned car roof rack;

[0055] During the process of cleaning and polishing the surface of the car roof rack, the second motor 911 is turned on. The driving end of the second motor 911 drives the corresponding drive shaft 907 to rotate slowly through the pulley transmission group. The drive shaft 907 on the side close to the second motor 911 drives the transmission shaft 912 to rotate through the first bevel gear 913 and the second bevel gear 914. The transmission shaft 912 drives the corresponding drive shaft 907 to rotate through the third bevel gear 916 and the fourth bevel gear 917. The two drive shafts 907 rotate in the same direction to drive the turntable 908 to rotate synchronously. The rotation of the turntable 908 drives the two swing shafts 901 to rotate in the same direction with small amplitude and repeatedly through the fork 909 and the swing frame 906. The swing shaft 901 drives a plurality of synchronizing shafts 902 to rotate synchronously with small amplitude and repeatedly through the fixing block 903 and the connecting rod 904. The synchronous and repeated rotation of the swing shaft 901 and the synchronizing shaft 902 drives the car roof rack to swing synchronously with small amplitude through the positioning rod 905.
