Description

Technical Field

[0001] The invention relates to the technical field of automobile fastener maintenance, in particular to a cleaning device for automobile fasteners. Background Art

[0002] Automotive fasteners play a vital role in automobile manufacturing and maintenance. They are used to connect and fix various parts of the automobile, mainly including bolts, screws, washers, locking nuts and fasteners. During the assembly process, lubricants are usually added to nuts and bolts to reduce friction and prevent rust. During the operation of the automobile, dust, dirt and other pollutants in the environment mix with the lubricating oil to form oil stains attached to the inner wall of the nut thread. The presence of oil stains on the nut thread leads to insufficient torque actually applied during the tightening process, which will cause the nut to fail to achieve the designed tightening effect and increase the risk of loosening of the connecting parts. During the maintenance and cleaning process of automobile fastening nuts, the space inside the nut may be small and difficult to clean directly with conventional tools, especially nuts with complex depth or shape. Secondly, when the nuts are concentrated and cleaned, the piled nuts will block each other, resulting in uneven cleaning effect. At the same time, the nuts will rub and collide with each other during the cleaning process, resulting in appearance damage or performance degradation, increasing the risk of future use. In response to the above problems, the inventor proposes a cleaning device for automotive fasteners to solve the above problems. Summary of the invention

[0044] By adopting the above technical solution, the second motor 712 drives the lower driving shaft 710 to rotate.

[0045] The driving shaft 710 located at the top is connected to the rotating shaft 307 through a synchronous wheel transmission group.

[0046] By adopting the above technical solution, the driving shaft 710 rotates and at the same time drives the rotating shaft 307 to rotate through the synchronous wheel transmission group.

[0047] A spacer block 310 used in conjunction with the two rubber diverter frames 304 is fixedly disposed on the inner wall of the fixed frame 301 close to the transfer frame 11 .

[0048] By adopting the above technical solution, the two rubber diverter frames 304 and the spacer block 310 cooperate with each other to divert the nut.

[0049] Working principle: First, the nuts to be cleaned are put into the feed frame 10 through the external conveying device, and the nuts enter the fixed frame 301 along the feed frame 10. Figure 4 , Figure 7 As shown, the second motor 712 is controlled to be turned on, and the driving end of the second motor 712 drives the lower driving shaft 710 to rotate one circle clockwise through the synchronous wheel transmission group, and the lower driving shaft 710 drives the upper driving shaft 710 to rotate one circle clockwise synchronously through the synchronous wheel transmission group, and the upper driving shaft 710 drives the rotating shaft 307 to rotate one circle through the synchronous wheel transmission group. Every time the rotating shaft 307 rotates one circle, the driving shaft 303 is driven to rotate one-sixth of the circle counterclockwise through the driving wheel 309 and the driven wheel 308. The driving shaft 303 drives the driven shaft 302 to rotate one-sixth of the circle clockwise synchronously through the driving gear 306 and the driven gear 305. The driving shaft 303 and the driven shaft 302 are synchronously rotated in the opposite direction to drive the corresponding two rubber diverter frames 304 to rotate synchronously, and the two nuts are respectively transported to the two transfer frames 11 under the action of the spacer 310. The nuts slide down to the limiting wheel 703 under the guidance of the transfer frame 11, and then as shown Figure 3 , Fig.10 As shown, the driving end of the electric cylinder 520 is controlled to push the sliding cleaning frame 501 to approach the nut under the guidance of the slide rail 519. The sliding cleaning frame 501 drives the guide plate 806 to move synchronously through the connecting frame 521 during the movement. The guide plate 806 drives the lifting frame 803 through the guide column 805 and the inclined groove 807 during the movement and descends under the guidance of the second guide rail 802, so that the clamping frame 804 contacts the nut to clamp and fix the nut, and then the high-pressure steam generator 9 is controlled to be turned on. The high-pressure steam generator 9 generates a large amount of high-pressure steam, which is respectively transported to the corresponding sliding frame 505 through the connecting pipe 518 and the bellows 517, and enters the rotating frame 507 along the sliding frame 505 and is ejected from the air hole, as shown in FIG. Figure 3 , Figure 5 and Figure 6As shown, the driving end of the No. 1 motor 516 is controlled to rotate, and the No. 1 motor 516 drives the lower worm 503 to rotate. The lower worm 503 drives the upper worm 503 to rotate synchronously through the synchronous wheel transmission group. The worm 503 drives the rotating frame 507 to rotate through the sliding shaft 504 and the fixed shaft 506. During the rotation process, the worm 503 drives the rotating shaft 508 to rotate through the worm wheel 509. The rotating shaft 508 drives the swing frame 511 to swing back and forth with the rotating connection with the fixed block 510 as the axis through the eccentric wheel 512 and the connecting rod 513. During the swinging process, the swing frame 511 drives the sliding frame 505 to reciprocate synchronously through the guide bolt 514. Fixed guide blocks are provided on both sides of the sliding frame 505 to prevent the sliding frame 505 from sliding too much. During the process, the sliding frame 505 reciprocates horizontally so that the rotating frame 507 first passes through the nut, so that the high-pressure steam rotates and evenly sprays on the inner wall of the nut thread, and at the same time cooperates with the cleaning brush 515 to reciprocate to clean the inner wall of the nut thread. After the nut thread is cleaned, the No. 1 motor 516 is turned off and the driving end of the electric cylinder 520 is controlled to retract and reset. During this process, the sliding cleaning frame 501 is reset and the clamping frame 804 rises and resets to stop clamping and fixing the nut, and then the No. 2 motor 712 is controlled to continue to rotate clockwise for one circle. During this process, the driving shaft 710 rotates through the rotating rod 711 and the second limit frame 709 to drive the slider 707 to reciprocate horizontally once under the guidance of the No. 1 guide rail 706. During the movement of the slider 707, Figure 8 As shown, the slider 707 drives the limiting wheel 703 to rotate back and forth once clockwise and then counterclockwise around the fixed column 702 through the first limiting frame 708, the arc groove 705 and the guide shaft 704. During the clockwise rotation of the limiting wheel 703, the cleaned nuts slide into the feeding frame 12 and are discharged along the feeding frame 12 for the next processing step. During the rotation of the driving shaft 710, the rubber diverter frame 304 is driven to continue to rotate according to the same steps above to transport the nuts to be cleaned, thereby reciprocatingly cleaning the inner wall of the nut thread.
