Description

Technical Field

[0001] This invention relates to the field of bearing cleaning technology, and specifically to a bearing brush cleaning machine. Background Technology

[0002] Bearings are essential components of mechanical equipment, primarily used to support the rotation of mechanical parts, reduce friction during rotation, and improve stability and rotational accuracy. During bearing production, the inner ring of the bearing needs to be cleaned, especially the raceways on the inner ring where the balls roll, which are prone to accumulating oil, dirt, and impurities.

[0003] Existing bearing cleaning methods generally involve soaking or spraying. However, for bearings with high precision and small size, simple soaking or spraying cannot meet the cleaning requirements of the bearing inner hole and is difficult to remove dirt from the bearing inner ring. Therefore, manual cleaning is usually carried out using tools such as brushes. This method has a low degree of automation, a large workload for operators, and low cleaning efficiency, making it difficult to meet the cleaning requirements of large-volume bearings.

[0024] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention uses a feeding tray to carry bearings to be cleaned. The bearings are sequentially fed from the tray's outlet end to the inlet end of the bearing positioning assembly 6. The bearing positioning assembly 6 supports and positions the bearings, ensuring that the bearings on it correspond to the brushing section of the brush drive assembly 5. The brush drive assembly 5 is controlled to move vertically, allowing its brushing section to insert downwards into the bearings for cleaning. After cleaning, the bearing positioning assembly 6 locks the cleaned bearings in place and collects them, thus achieving continuous automatic cleaning. Compared to traditional manual cleaning with brushes, this invention provides better cleaning results, higher efficiency, and reduced labor costs, meeting the needs of large-scale bearing cleaning.

[0026] Specifically, such as Figure 1 As shown, a bearing brush cleaning machine includes a base 1, a feeding tray, and a cleaning device 2. The feeding tray and the cleaning device 2 are spaced apart on the top of the base 1. The discharge end of the feeding tray is connected to the feed end of the cleaning device 2. The cleaning device 2 includes a mounting base plate 3, a mounting bracket 4, a brush drive assembly 5, and a bearing positioning assembly 6. The mounting base plate 3 is mounted on the base 1, the mounting bracket 4 is mounted on the base 1, and the bearing positioning assembly 6 is mounted on the mounting bracket 4. The feed end of the bearing positioning assembly 6 is connected to the discharge end of the feeding tray. The brush drive assembly 5 is vertically and flexibly mounted above the bearing positioning assembly 6. The lower end of the brush drive assembly 5 is mounted on the mounting base plate 3. The brushing part of the brush drive assembly 5 can be inserted downward into the clamping part of the bearing positioning assembly 6 for fixing the bearing to be cleaned.

[0027] Furthermore, such as Figures 1 to 3As shown, the brush drive assembly 5 includes a mounting plate 7, a lifting drive structure 8, a rotating drive structure 9, multiple vertical rods 10, and multiple brush heads 11. The multiple vertical rods 10 are spaced apart and supported on the mounting base plate 3. The mounting plate 7 is movably fitted onto the multiple vertical rods 10. The fixing part of the lifting drive structure 8 is located at the upper end of the multiple vertical rods 10, and the driving part of the lifting drive structure 8 is drivenly connected to the mounting plate 7. The multiple brush heads 11 are sequentially and rotatably arranged at the edge of the mounting plate 7, with the lower ends of each brush head 11 extending downwards from the bottom of the mounting plate 7. The rotating drive structure 9 is mounted on the mounting plate 7, and its drive shaft is drivenly connected to the multiple brush heads 11. By fixing the lifting drive structure 8 on the mounting plate 7 to drive the multiple brush heads 11 to move vertically, it ensures that the lower ends of the brush heads 11 can smoothly insert into the bearing to be cleaned, and that the brush heads 11 can promptly retract from the bearing after cleaning. The rotating drive structure 9 is used to drive the multiple brush heads 11 to rotate to achieve the purpose of cleaning the bearing.

[0028] Furthermore, such as Figure 1 As shown, the lifting drive structure 8 includes a drive base 12, a lifting cylinder 13, and multiple sleeves 14. The mounting plate 7 has multiple mounting holes, and the multiple sleeves 14 are fitted into these holes one-to-one. Multiple vertical rods 10 pass through the multiple sleeves 14 one-to-one. The drive base 12 is fixedly mounted on the upper ends of the multiple vertical rods 10. The lifting cylinder 13 is mounted on the drive base 12, and its driving part extends downwards and connects to the mounting plate 7. The drive base 12 is used to mount the lifting cylinder 13, and the multiple sleeves 14 are provided to ensure smoother movement of the mounting plate 7 along the multiple vertical rods 10.

[0029] Furthermore, such as Figure 2 and Figure 3As shown, the rotary drive structure 9 includes a rotary drive component 15 and a first pulley 16. The rotary drive component 15 is disposed at the bottom of the mounting plate 7, and a through hole is provided on the mounting plate 7. The drive shaft of the rotary drive component 15 passes through the through hole upward. The first pulley 16 is disposed on the drive shaft of the rotary drive component 15. Two sets of relatively spaced first annular grooves 17 are provided on the sides of multiple brush heads 11. The two first annular grooves 17 of the brush head 11 are respectively connected to the corresponding first annular grooves 17 of two adjacent brush heads 11 by a first belt 36. At least one brush head 11 is provided with a second annular groove 18 on its side. A second belt 19 is wound between the second annular groove 18 and the first pulley 16. The rotary drive 15 drives the first pulley 16 to rotate. The first pulley 16 transmits torque to the brush head 11 with the second annular groove 18 through the second belt 19. Since adjacent brush heads 11 are connected in sequence through the first belt 36, other brush heads 11 can be driven to rotate to clean the bearing to be cleaned. The rotary drive 15 alone can drive the rotation of all brush heads 11, reducing production costs.

[0030] Furthermore, such as Figure 3 As shown, each of the multiple brush heads 11 includes a brush cylinder 20, a bearing cover 21, a rotating shaft 22, and a brush strip 23. The mounting plate 7 has multiple shaft holes, the bearing cover 21 is set corresponding to the shaft holes, the rotating shaft 22 is rotatably mounted on the bearing cover 21, the brush strip 23 is set at the lower end of the rotating shaft 22 extending out of the mounting plate 7, the brush cylinder 20 is set at the upper end of the rotating shaft 22, and the first annular groove 17 and the second annular groove 18 are both opened on the side of the brush cylinder 20.

[0031] Furthermore, such as Figures 1 to 4 As shown, the bearing positioning assembly 6 includes a height adjustment bracket 24, a material feed seat 25, a clamping material feed component 26, and a telescopic cylinder 27. The material feed seat 25 is mounted on the mounting bracket 4. The end of the material feed seat 25 has a feed hole communicating with the feeding tray. The top of the material feed seat 25 has multiple slots 28 spaced apart. Each slot 28 has a through-hole 29 spaced apart. The height adjustment bracket 24 is mounted on the mounting base plate 3. The telescopic cylinder 27 is mounted on the upper end of the height adjustment bracket 24. The driving end of the telescopic cylinder 27 is provided with a clamping material feed component 26. The clamping end of the clamping material feed component 26 protrudes outward to form multiple clamping parts and support parts. The multiple clamping parts and support parts are arranged sequentially up and down and correspond one-to-one with the multiple material feed holes 29.

[0032] Furthermore, such as Figure 1 and Figure 5 As shown, a cover plate 30 is provided on the top of the material receiving seat 25. Multiple through holes are provided on the top surface of the cover plate 30, and the multiple through holes of the cover plate 30 correspond one-to-one with the multiple material receiving holes 29.

[0033] Furthermore, such as Figures 4 to 6 As shown, the clamping feeder 26 includes a feed plate 31 and a pressure plate 32. There are two telescopic cylinders 27, both of which are mounted on the height adjustment bracket 24 and are driven and connected to the feed plate 31 and the pressure plate 32 respectively. The end of the feed plate 31 away from the telescopic drive component protrudes outward to form multiple receiving baffles 33. The multiple receiving baffles 33 are inserted into and cooperate with multiple slots 28 in a one-to-one correspondence. Each of the multiple receiving baffles 33 has a bearing hole, which corresponds to the feed hole 29. The end of the pressure plate 32 away from the telescopic drive component protrudes outward to form multiple locking blocks 34. The positions of the multiple locking blocks 34 correspond one-to-one with the positions of the multiple receiving baffles 33. By setting up a material drag plate 31 to provide support for the bearing to be cleaned, the bearing to be cleaned is prevented from falling into the material passage hole 29 of the material passage seat 25. After cleaning, the material drag plate 31 is retracted by the telescopic cylinder 27, which can automatically drop the cleaned bearing through the material passage hole 29. A pressure plate 32 is set up to fix the bearing to be cleaned, so as to prevent the bearing from shifting during the cleaning process and causing damage to the bearing and the brush head 11.

[0034] Furthermore, such as Figure 4 As shown, the middle of the outer end of the retaining block 34 is recessed inward to form a concave portion, and the concave surface of the concave portion fits against two adjacent surfaces of the bearing to be cleaned. By providing a concave surface at the outer end of the retaining block 34, not only can better support and fixation be provided for the bearing to be cleaned, but it can also play a positioning role for the bearing, so as to achieve a stable and effective cleaning effect on the bearing to be cleaned.

[0035] Furthermore, such as Figure 1 and Figure 3 As shown, the bearing brush cleaning machine also includes a receiving tray 35 mounted on the mounting bracket 4. The receiving tray 35 is located below the bearing positioning assembly 6, and the side of the receiving tray 35 away from the bearing positioning assembly 6 is inclined downward and has an opening. By setting up the receiving tray 35, bearings falling from the material passage hole 29 can be received, so as to achieve centralized storage of bearings. Since the opening side of the receiving tray 35 is inclined downward, a transfer structure can be set at the opening of the receiving tray 35 to transfer the cleaned bearings away in a timely manner.

[0036] In use, the bearings to be cleaned are continuously placed into the feeding tray, which then feeds them sequentially into the material receiving seat 25 through the discharge end. The bearings entering the material receiving seat 25 are moved onto the corresponding drag plate 31 by mutual compression. The telescopic cylinder 27 pushes the pressure plate 32 outward to fix the bearings to be cleaned. Simultaneously, the lifting cylinder 13 drives the mounting plate 7 downward to ensure that the brush head 11 mounted on the mounting plate 7 moves downward until the brush strip 23 is inserted into the bearing. At the same time, the rotary drive 15 drives the first pulley 16 to rotate, and... The second belt 19 drives the corresponding brush head 11 to rotate. Since the first annular groove 17 on two adjacent brush heads 11 is connected by the first belt 36, multiple brush heads 11 can rotate synchronously. The brush strip 23 can clean the bearing. After cleaning, the upgrading cylinder moves the mounting plate 7 upwards, so that the brush head 11 moves away from the bearing. Then, the telescopic cylinder 27 retracts, first releasing the pressure plate 32 from fixing the bearing, and then releasing the material receiving baffle 33 of the drag plate 31 from blocking the slot 28. The cleaned bearing can then fall through the material hole 29 into the receiving tray 35 for collection. By repeating the above steps, continuous cleaning of the bearing can be achieved. This invention can automatically clean large quantities of bearings, and compared to traditional manual brushing, it not only has higher cleaning efficiency but also better cleaning effect.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
