Description

Technical Field

[0001] The present invention relates to the technical field of self-lubricating bearing processing, and more particularly to a processing system and method for a self-lubricating bearing. Background Art

[0002] Self-lubricating bearings are categorized as composite, solid-inlaid, bimetallic, and special-material bearings. Different bearings are selected based on their application and operating conditions. They offer high load capacity, impact resistance, high-temperature resistance, and strong self-lubrication. They are widely used in metallurgical continuous casting machines, rolling mills, mining machinery, molds, and lifting machinery. During the manufacturing process, after polishing, the bearings are sprayed with epoxy anti-rust coatings, PTFE anti-friction coatings, and other coatings. Before spraying, the bearing surface must be cleaned of dust and dried to prevent any subsequent coating issues.

[0003] The Chinese invention patent application number 202410404665.2 discloses a coating spraying device for bearing processing, including a servo conveyor belt and a collection basket. Collection baskets are provided at both ends of the servo conveyor belt. The conveying surface of the servo conveyor belt is provided with multiple brackets. A spraying mechanism is provided on the outside of the servo conveyor belt. Drying mechanisms are provided at both ends of the spraying mechanism. The spraying mechanism includes a spray box, a liquid storage tank, a cylinder, a support rod, a nozzle, a baffle and an electric clamp. The drying mechanism includes a drying box, a fan, an electric heating rod and a grid. The device can remove moisture from the surface of the bearing before coating spraying, keep the bearing dry, and ensure the spraying effect. The bracket for placing the bearing facilitates the positioning of the bearing during the spraying process to ensure the quality of the coating spraying. The two-stage spraying design can avoid the influence of the bracket on the uniformity of the bearing spraying. However, there is no integrated pretreatment function for cleaning the outer surface of the bearing. The bearing can only be cleaned in conjunction with other cleaning equipment, and then the cleaned bearing is transferred to the bearing processing coating spraying device for drying and spraying the bearing. The functionality is low, which affects the continuity of the bearing processing line and reduces the processing efficiency. In addition, drying mechanisms are set at both ends of the spraying mechanism to realize the drying operations of the cleaned bearings and the sprayed bearings. It is not possible to use a set of drying mechanisms to realize the drying of the cleaned bearings and the drying of the sprayed bearings, which increases the complexity of the equipment and the drying cost. At the same time, since the bracket itself blocks part of the outer surface of the bearing when the bracket fixes the bearing, it will affect the uniformity of the spraying. Although a two-stage spraying design is adopted to reduce the interference of the bracket spraying uniformity, it means that the bearing spraying angle or position needs to be adjusted during the two-stage spraying process to ensure that the blocked area can also be sprayed, which increases the time and complexity of the spraying.

[0004] Chinese invention patent application number 201810675339.X discloses a spraying fixture. By arranging a housing, bearing, threaded column, threaded sleeve, connecting block, connecting plate, connecting groove, limiting column, roller, movable plate, limiting groove, fixing plate, slide bar, clamping plate, fixing plate, and spraying device, the device solves the problem that existing spraying devices cannot fix mechanical parts, thus causing mechanical parts to move during the spraying process. However, the device cannot fix bearings with different inner diameters, resulting in low versatility. Furthermore, the device cannot rotate the fixed bearing during the spraying process to facilitate the spraying device to fully spray the bearing's axial outer surface. Summary of the Invention

A drain pipe connected to the washing liquid is provided on the chassis, and a valve is installed on the drain pipe.

[0015] A method for processing a self-lubricating bearing comprises the following steps:

[0016] S1. Adjust the bending degree of the elastic strip according to the inner diameter of the bearing, and fix the bent parts at both ends of the elastic strip to the gourd holes at the corresponding positions on the main pipe to fix the elastic strip on the main pipe. Place multiple bearings on the base of the elastic positioning unit respectively. At this time, the elastic strip is deformed under the pressure of the inner wall of the bearing, and the inner wall of the bearing contacts part of the surface of the elastic strip, thereby fixing the bearing. After the bearing is fixed on the base, adjust the movable rod to make the cleaning sponge contact with the circumferential outer surface of the bearing.

[0017] S2. Pour the cleaning liquid into the chassis through the opening. At this time, close the valve on the drain pipe and cover the chassis.

[0018] S3. Start the belt transmission device to rotate the belt, and engage the first teeth and the second teeth to rotate, so that the bases of the several elastic positioning units rotate, and then the bearings fixed thereon rotate. The controller controls the solenoid valve on the water pipe to open and the solenoid valve on the air pipe to close. The water pump and the industrial water purifier work to transport the cleaning liquid into the collection pipe and then spray it out through the gas-liquid dual-purpose nozzle to comprehensively clean the rotating bearings. The cleaning liquid after cleaning the bearings falls back into the washing liquid area through the opening for reuse. The setting of the industrial water purifier is used to filter the dust particles and spray paint mixed in the cleaning liquid to avoid secondary contamination of the bearings. In this process, since the cleaning sponge is in contact with the circumferential outer surface of the bearing, under the condition of the bearing rotating, the cleaning sponge further cleans the dust, stains, etc. on the surface of the bearing, thereby improving the cleaning effect.

[0019] S4. After the bearing cleaning operation is completed, the water pump and industrial water purifier stop working. The controller controls the solenoid valve on the water pipe to close and the solenoid valve on the air pipe to open. The hair dryer blows hot air through the air pipe into the collecting pipe, where the gas-liquid dual-purpose nozzle sprays out to dry the bearing after cleaning. The exhaust hole on the machine cover is used to relieve pressure. Since the bearing keeps rotating, the hot air blown by the gas-liquid dual-purpose nozzle can evenly dry the bearing, thereby improving the drying effect and efficiency.

[0020] S4. After the drying operation of the bearing after cleaning is completed, the hair dryer stops working, and the spraying device works to evenly spray the rotating bearing to complete the bearing spraying operation.

[0021] S5. After the spraying operation of the bearing is completed, the spraying device stops working, and the hair dryer starts again to blow out hot air through the air pipe into the collection pipe, and the gas-liquid dual-purpose nozzle sprays out to dry the bearing after spraying. The drying operation of the bearing after spraying is completed, and the rotation of the bearing is conducive to the uniform drying of the bearing after spraying.

[0022] S6. After the drying operation of the bearing after spraying is completed, the hair dryer stops working. After a period of time, the box cover is opened to avoid a sudden drop in temperature that affects the processing quality of the bearing. After opening the box cover, the belt drive device continues to work for a period of time to keep the bearing rotating, which is conducive to accelerating cooling. After the bearing cools down, the elastic strip is elastic, so the bearing can be directly removed from the base and replaced with the next batch of bearings to be processed.

[0023] By adopting the above technical solution, the beneficial effects of the present invention are:

[0024] 1. The self-lubricating bearing processing system designed in the present invention integrates the pretreatment operation of cleaning the outer surface of the bearing, the drying operation after the bearing is cleaned, the spraying operation of the bearing, and the drying operation after the bearing is sprayed, thereby enhancing functionality, improving the continuity of the bearing processing steps, and improving processing efficiency. The cleaning, cleaning and drying of the bearing and the drying of the sprayed bearing are realized through the cleaning and drying unit, reducing the complexity and drying cost of the self-lubricating bearing processing system.

[0025] 2. Bearings with different inner diameters are fixed by elastic positioning units to achieve the fixation of various bearings. The elastic strip is disassembled and connected with the gourd holes at different positions on the main pipe. The contact point position between the elastic strip and the inner wall of the bearing can be adjusted according to the type of bearing to better adapt to the fixation of different types of bearings. Therefore, the self-lubricating bearing processing system is suitable for the fixation of bearings of various sizes for cleaning, cleaning and drying, spraying and spray drying processes, with strong versatility and high practicality.

[0026] 3. The elastic positioning unit cooperates with the belt transmission device to make the bearing fixed by the elastic positioning unit rotate during the spraying process so that the spraying device can spray the axial outer surface of the bearing in one go, avoiding the need for secondary spraying, reducing the complexity of the spraying operation, and also facilitating the cleaning and drying unit to perform more comprehensive cleaning and drying operations on the bearing, thereby improving the bearing spraying, cleaning and drying effects.

DETAILED DESCRIPTION

[0036] Reference Figures 1 to 8 The embodiments of the present invention are further described.

[0037] The present invention discloses a self-lubricating bearing processing system, including a chassis 1 and a belt transmission device 100 and a spraying device 200 arranged in the chassis 1. The belt transmission device 100 and the spraying device 200 are both existing technologies and will not be described in detail here. The chassis 1 is provided with an elastic positioning unit 300 for fixing the bearing 100 and a cleaning and drying unit 400 for cleaning and drying the bearing 100. The elastic positioning unit 300 is provided with several and is arranged around the belt transmission device 100. The spraying device 200 is provided with several and corresponds one-to-one to the bearings 100 fixed on the several elastic positioning units 300. The chassis 1 is provided with a cleaning liquid for cleaning the bearing 100 (the cleaning liquid is not drawn in the accompanying drawings). The cleaning liquid can select a suitable cleaning agent according to the cleaning needs. The present invention takes removing dust on the surface of the bearing 100 as an example and uses clean water as the cleaning liquid.

[0038] like Figure 1 As shown, multiple bearings 100 are fixed respectively by a number of elastic units, and the fixed bearings 100 are rotated by the cooperation of the belt transmission device 100 and the several elastic units, so that the cleaning and drying unit 400 outputs the cleaning liquid to the outer surface of the bearing 100 through the water pump 2 and the gas-liquid dual-purpose nozzle 7 to clean the bearing 100, and cooperates with the hair dryer 4 and the gas-liquid dual-purpose nozzle 7 of the cleaning and drying unit 400 to dry the bearing 100.

[0039] The cleaning and drying unit 400 includes a water pump 2, a water pipe 3, a blower 4, an air pipe 5, a collection pipe 6, a controller and a plurality of gas-liquid dual-purpose nozzles 7. The water pump 2 and the blower 4 are both installed outside the chassis 1. An industrial water purifier 26 corresponding to the water pump 2 is provided outside the chassis 1. The collection pipe 6 is annular and installed inside the chassis 1. The belt of the belt drive device 100 surrounds the collection pipe 6. The input end of the industrial water purifier 26 is connected to the cleaning liquid in the chassis 1 through a pipeline. The output end of the industrial water purifier 26 is connected to the input end of the water pump 2. The water pipe 3 is connected to the output end of the water pump 2, the output end of the hair dryer 4 is connected to one end of the air pipe 5, the other end of the air pipe 5 and the other end of the water pipe 3 are both connected to the collection pipe 6, a plurality of gas-liquid dual-purpose nozzles 7 correspond one-to-one to the plurality of elastic positioning units 300, and the plurality of gas-liquid dual-purpose nozzles 7 are connected to the collection pipe 6, and electromagnetic valves for controlling the connection or closing of the pipelines are respectively installed on the water pipe 3 and the air pipe 5, and a controller is electrically connected to the electromagnetic valves on the water pipe 3 and the electromagnetic valves on the air pipe 5 (the controller and the electromagnetic valves are not shown in the drawings).

[0040] The elastic positioning unit 300 includes a base 8 that cooperates with the belt transmission device 100, a main pipe 9 vertically installed at the center of the base 8, and an elastic strip 10 movably connected to the main pipe 9. The base 8 is rotatably connected to the chassis 1. The elastic strip 10 is arranged along the height direction of the main pipe 9. The elastic strip 10 is made of a deformable and resilient metal material. The elastic strip 10 is selected to be made of spring steel. The main pipe 9 is a hexagonal tube. There are six elastic strips 10 and they correspond to the six sides of the main pipe 9 respectively. A silicone strip 17 is provided on the elastic strip 10 along the length direction of the elastic strip 10. A number of gourd holes 13 are opened on the six sides of the main pipe 9. The gourd holes 13 are evenly arranged on the same straight line along the height direction of the main pipe 9, and the gourd holes 13 are divided into two groups. One group of gourd holes 13 is placed forward, and the other group of gourd holes 13 is inverted. The two groups of gourd holes 13 is symmetrically arranged on the main pipe 9, and both ends of the elastic strip 10 include a bent portion 14 bent toward the direction close to the main pipe 9. The bent portion 14 at one end of the elastic strip 10 is detachably connected to the inverted gourd hole 13, and the bent portion 14 at the other end of the elastic strip 10 is detachably connected to the positive gourd hole 13. A fixing rod 15 and a circular plate 16 mounted on the fixing rod 15 are installed on the bent portion 14. The fixing rod 15 is movably connected to the gourd hole 13. The diameter of the circular plate 16 is smaller than the diameter of the large hole body of the gourd hole 13, and the diameter of the circular plate 16 is larger than the diameter of the small hole body of the gourd hole 13. The circular plate 16 is movably connected to the large hole body of the gourd hole 13, and the circular plate 16 is clamped with the small hole body of the gourd hole 13. The bearing 100 is placed on the base 8, and the six elastic strips 10 are bent and contact the inner wall of the bearing 100 through the silicone strip 17 to fix the bearing 100.

[0041] The belt of the belt transmission device 100 is equipped with a plurality of first teeth 11 arranged around the belt, and the base 8 is equipped with a plurality of second teeth 12 arranged around the base 8. The plurality of first teeth 11 and the plurality of second teeth 12 are engaged with each other to make the base 8 rotate in the chassis.

[0042] like Figure 1-6 As shown, since the elastic strip 10 is made of spring steel, an external force is applied to the elastic strip 10 to bend it, and the curvature is adjusted according to the inner diameter of the bearing 100. Then, the position of the elastic strip 10 on the main pipe 9 is adjusted to ensure that the surface of the bent elastic strip 10 can correspond to and contact the inner wall of the bearing 100. At this time, the bent portions 14 at both ends of the elastic strip 10 correspond to the inverted gourd hole 13 and the positive gourd hole 13 respectively, and after the fixing rod 15 on the bent portion 14 and the circular plate 16 on the fixing rod 15 pass through the large hole body of the corresponding gourd hole 13, the fixing rod 15 is clamped with the small hole body of the corresponding gourd hole 13 under the action of the elastic force of the elastic strip 10, and the diameter of the matching circular plate 16 is larger than the diameter of the small hole body of the gourd hole 13. Prevent the fixing rod 15 from disengaging from the corresponding gourd hole 13, complete the fixation of the elastic strip 10 on the main pipe 9, and when the elastic strip 10 needs to be removed, force is applied to the elastic strip 10 to make the bent portions 14 at both ends approach each other. At this time, the fixing rod 15 on the bent portion 14 enters the large hole body of the gourd hole 13, and the diameter of the circular plate 16 is smaller than the large hole body diameter of the gourd hole 13 to facilitate the circular plate 16 to disengage from the gourd hole 13, thereby removing the elastic strip 10 from the main pipe 9, realizing the detachable connection between the elastic strip 10 and the corresponding gourd hole 13 through the bent portion 14, which is convenient for adjusting the bending degree of the elastic strip 10 and the position on the main pipe 9 according to the inner diameter and height of the bearing 100 to adapt to the fixation of different types of bearings 100.

[0043] After the elastic strip 10 is fixed, the bearing 100 is put on the main pipe 9. Since the elastic strip 10 is elastic, the elastic strip 10 is compressed and deformed under the action of the inner wall of the bearing 100 to further adapt to the inner diameter of the bearing 100 and conflict with the inner surface of the bearing 100. The six elastic strips 10 cooperate to fix the bearing 100 on the base 8, so that the elastic positioning unit 300 can adjust the contact point position of the elastic strip 10 and the inner wall of the bearing 100 according to the type of bearing 100 to better adapt to the fixation of different types of bearings 100, thereby realizing that the processing system of the self-lubricating bearing 100 of the present invention is adapted to the fixation of bearings 100 of various sizes for subsequent cleaning, cleaning and drying, spraying and spray drying processes, with strong versatility and high practicality.

[0044] The motor of the belt transmission device 100 drives the belt to move. The belt is equipped with a plurality of first teeth 11, which mesh with the second teeth 12 on the base 8 of the elastic positioning unit 300. When the belt moves, the meshing of the teeth drives the base 8 to rotate, thereby causing the bearing 100 fixed on the base 8 to rotate. The elastic positioning unit 300 cooperates with the belt transmission device 100 to rotate the bearing 100 fixed to the elastic positioning unit 300.

[0045] The controller controls the solenoid valve on the water pipe 3 to open and the solenoid valve on the air pipe 5 to close, and the water pump 2 and the industrial water purifier 26 to work. The industrial water purifier 26 delivers the cleaning liquid to the water pump 2. The water pump 2 delivers the cleaning liquid to the collecting pipe 6 through the water pipe 3, and then sprays it out through the gas-liquid dual-purpose nozzle 7 to fully clean the rotating bearing 100, completing the cleaning operation of the bearing 100. The base 8 can be made of a circular plate 16 with holes, so that when the cleaning liquid falls into the bearing 100, it can flow out from the holes on the base 8 to avoid the accumulation of the cleaning liquid in the inner cavity of the bearing 100. After cleaning the bearing 100, the cleaning liquid falls back to the washing liquid area 28 through the opening 34 on the mounting plate 27 for reuse. The setting of the industrial water purifier 26 is used to filter the dust particles mixed in the cleaning liquid to avoid secondary pollution of the bearing 100, thereby realizing the recycling of the cleaning liquid, reducing waste liquid discharge, and being green and environmentally friendly.

[0046] After the cleaning operation of the bearing 100 is completed, the water pump 2 and the industrial water purifier 26 stop working, the solenoid valve on the water pipe 3 is closed and the solenoid valve on the air pipe 5 is opened through the controller, and the hair dryer 4 blows out hot air through the air pipe 5 into the collecting pipe 6, where the gas-liquid dual-purpose nozzle 7 sprays out to dry the bearing 100 after cleaning. The exhaust hole 24 on the machine cover is used to release pressure to maintain the air pressure in the chassis 1 stable. During this process, the bearing 100 keeps rotating, so that the hot air blown by the gas-liquid dual-purpose nozzle 7 can evenly dry the bearing 100, thereby improving the drying effect and efficiency.

[0047] After the drying operation of the bearing 100 is completed after cleaning, the hair dryer 4 stops working, and the spraying device 200 works to evenly spray the rotating bearing 100, so that the spraying device 200 can spray the axial outer surface of the bearing 100 in one go, completing the spraying operation of the bearing 100, avoiding the need for secondary spraying, reducing the complexity of the spraying operation, and spraying evenly, thereby improving the spraying effect.

[0048] After the spraying operation of the bearing 100 is completed, the spraying device 200 stops working, and the hair dryer 4 starts again to blow out hot air through the air pipe 5 into the collecting pipe 6, and the gas-liquid dual-purpose nozzle 7 sprays out to dry the bearing 100 after spraying, completing the drying operation of the bearing 100 after spraying. Combined with the rotation of the bearing 100, it is beneficial to the uniform drying of the bearing 100 after spraying, and improves the quality of the finished product of the processed bearing 100.

[0049] After the processing of this batch of bearings 100 is completed, the bearings 100 are removed and replaced with the next batch of bearings 100 to be processed, and the above operations are repeated for cleaning, drying, spraying, and drying, so that the self-lubricating bearing 100 processing system can be recycled. When the self-lubricating bearing 100 processing system is recycled, a small amount of spray paint will be contaminated on the base 8 after the spraying operation of the previous batch of bearings 100. When the next batch of bearings 100 is cleaned, the cleaning liquid falling back into the washing liquid area 28 will be mixed with the spray paint. Therefore, the industrial water purifier 26 is selected to have the function of filtering dust particles and spray paint in the cleaning liquid, so that the industrial water purifier 26 can filter the used cleaning liquid for recycling. The industrial water purifier 26 that realizes this function is an existing technology. Specifically, the Jingkangle multi-media filter + Hyde Energy RO membrane combination can be selected to take into account both cost and filtering effect.

[0050] In summary, the self-lubricating bearing 100 processing system designed in the present invention integrates the pretreatment operation of cleaning the outer surface of the bearing 100, the drying operation of the bearing 100 after cleaning, the spraying operation of the bearing 100, and the drying operation of the bearing 100 after spraying, thereby enhancing functionality, having high integration, and occupying a small area. In addition, the continuity of the bearing 100 processing steps is improved, thereby improving processing efficiency, and the cleaning, cleaning, drying, and spraying drying of the bearing 100 are realized through the cleaning and drying unit 400, thereby reducing the complexity and drying cost of the self-lubricating bearing 100 processing system. In these processing steps, the self-rotation of the bearing 100 is conducive to the spraying device 200 and the cleaning and drying unit 400 to perform more comprehensive spraying, cleaning, and drying operations on the bearing 100, thereby avoiding the need for secondary spraying and reducing the complexity of the spraying operation. In combination with the elastic positioning unit 300 to fix bearings 100 of different inner diameters, the self-lubricating bearing 100 processing system is adapted to the fixing of bearings 100 of various sizes for cleaning, cleaning and drying, spraying, and spray drying processes, thereby having strong versatility and high practicality.

[0051] When the processed bearing 100 needs to be removed from the base 8, due to the elastic property of the elastic strip 10 that can deform and rebound, the processed bearing 100 can be directly pulled out from the elastic strip 10 of the main pipe 9. The operation is convenient and it is easy to replace the next batch of bearings 100 to be processed. The setting of the elastic silicone strip 17 avoids the hard contact between the surface of the elastic strip 10 and the inner surface of the bearing 100 when fixing or removing the bearing 100, thereby avoiding damage to the inner surface of the bearing 100.

[0052] The cleaning and drying unit 400 also includes a cleaning sponge 18 for cleaning the outer surface of the bearing 100. The cleaning sponge 18 is cylindrical and arranged along the height direction of the bearing 100. The cleaning sponge 18 is provided with several bearings 100 fixed on the elastic positioning units 300. The cleaning sponge 18 is connected with a movable rod for adjusting the position of the cleaning sponge 18 so that it contacts the surface of the corresponding bearing 100. The movable rod includes an extension rod 19 fixedly connected to the chassis 1 and a swing rod 20 connected to the cleaning sponge 18. The swing rod 20 is provided with several first positioning holes 21 arranged along the length direction of the swing rod 20. The extension rod 19 is provided with a second positioning hole 22 that cooperates with the first positioning hole 21. The first positioning hole 21 and the second positioning hole 22 are bolted together.

[0053] like Figure 1 、 Figure 3 and Figure 7 As shown, after the bearing 100 is fixed on the base 8, according to the diameter of the bearing 100, by adjusting the connection point position of the swing rod 20 and the extension rod 19 and the angle between the swing rod 20 and the extension rod 19, the cleaning sponge 18 connected to the swing rod 20 is in contact with the circumferential outer surface of the bearing 100, and the first positioning hole 21 at the corresponding position on the swing rod 20 is matched with the second positioning hole 22 on the extension rod 19, and the first positioning hole 21 and the second positioning hole 22 are bolted together to fix the extension rod 19 and the swing rod 20, so that the cleaning sponge remains in contact with the bearing 100. The outer surface is in contact with the state, so that during the rotation of the bearing 100 and the cleaning operation, the cleaning sponge 18 can further clean the dust and stains on the surface of the bearing 100, thereby improving the cleaning effect. By adjusting the connection point position of the swing arm 20 and the extension rod 19 and the angle between the swing arm 20 and the extension rod 19, the position of the cleaning sponge 18 can be flexibly adjusted so that the cleaning sponge 18 can contact the outer surfaces of different types of bearings 100 fixed on the base 8, thereby improving the flexibility and adaptability of the cleaning sponge 18, and helping to enhance the practicality of the self-lubricating bearing 100 processing system.

[0054] The chassis 1 is provided with a cover 23 for closing the opening 34 of the chassis 1 . The cover 23 is provided with an exhaust hole 24 and a groove 25 for cooperating with the wall of the chassis 1 . The cover 23 is detachably connected to the chassis 1 through the groove 25 .

[0055] like Figure 2 As shown, during the processing, the box cover 23 is covered on the chassis 1 so that the entire processing process is carried out in a closed environment to avoid external pollution. At the same time, the exhaust hole 24 is used to release pressure to achieve pressure balance in the chassis 1 when the box cover 23 is covered on the chassis 1.

[0056] The chassis 1 is provided with a mounting plate 27 for mounting the belt transmission device 100. The mounting plate 27 divides the internal space of the chassis 1 into a washing liquid area 28 and a working area 29. The elastic positioning unit 300, the cleaning and drying unit 400, and the spraying device 200 are all placed in the working area 29. The inner wall of the chassis 1 is provided with a fixing bracket 30 for mounting the spraying device 200. The motor of the belt transmission device 100 is mounted on the mounting plate 27. A transmission gear of the belt transmission device 100 is fixedly connected to the motor of the belt transmission device 100. The mounting plate 27 is provided with a fixing bracket 30 for fixing the spraying device 200. The support plate 31 of the fixed collection pipe 6, the support rod 32 rotatably connected to the base 8, the pillar 37 connected to the bottom inner wall of the chassis 1 and the shaft 33 cooperating with the belt transmission device 100, the shaft 33 is rotatably connected to another transmission gear of the belt transmission device 100, the cleaning liquid is placed in the cleaning liquid area 28, and the mounting plate 27 is provided with a plurality of openings 34 connecting the cleaning liquid area 28 and the working area 29. The plurality of openings 34 correspond one to one with a plurality of elastic positioning units 300 respectively. The chassis 1 is provided with a drain pipe 35 connected to the cleaning liquid, and a valve 36 is installed on the drain pipe 35.

[0057] like Figure 1 、 Figure 2 and Figure 8 As shown, the installation of mounting plate 27 rationally divides the internal space of chassis 1, enabling the elastic positioning unit 300, cleaning and drying unit 400, and spraying device 200 to be installed and fixed within chassis 1. The opening 34 facilitates the entry of cleaning liquid into washing area 28 and separates it from the elastic positioning unit 300, cleaning and drying unit 400, and spraying device 200. At the same time, the cleaning liquid sprayed by gas-liquid dual-purpose nozzle 7 in working area 29 to clean bearing 100 is returned to washing area 28 for filtration by industrial water purifier 26 and then recycled. During the processing, valve 36 on drain pipe 35 remains closed. When the cleaning liquid needs to be replaced, valve 36 on drain pipe 35 can be opened to discharge the cleaning liquid to be replaced through drain pipe 35.

[0058] A method for processing a self-lubricating bearing comprises the following steps:

[0059] S1. Adjust the bending degree of the elastic strip 10 according to the inner diameter of the bearing 100, and fix the bent portions 14 at both ends of the elastic strip 10 to the gourd holes 13 at the corresponding positions on the main pipe 9 to fix the elastic strip 10 on the main pipe 9. Place multiple bearings 100 on the base 8 of the elastic positioning unit 300. At this time, the elastic strip 10 is deformed under the pressure of the inner wall of the bearing 100, and the inner wall of the bearing 100 contacts part of the surface of the elastic strip 10, thereby fixing the bearing 100. Due to the elasticity of the elastic strip 10, the elastic strip 10 will adapt to the inner diameter of the bearing 100 and contact the inner wall of the bearing 100;

[0060] After the bearing 100 is fixed on the base 8 , the movable rod is adjusted so that the cleaning sponge 18 is in surface contact with the circumferential outer surface of the bearing 100 .

[0061] S2. Pour the cleaning liquid into the chassis 1 through the opening 34. At this time, the valve 36 on the drain pipe 35 is closed, and the chassis cover 23 is covered on the chassis 1.

[0062] S3. Start the belt conveyor to rotate the belt, and mesh the first teeth 11 and the second teeth 12, thereby rotating the bases 8 of the plurality of elastic positioning units 300, and further rotating the bearings 100 fixed thereon. The controller controls the solenoid valve on the water pipe 3 to open and the solenoid valve on the air pipe 5 to close. The water pump 2 and the industrial water purifier 26 operate to deliver the cleaning liquid into the collecting pipe 6, and then spray it through the gas-liquid dual-purpose nozzle 7 to fully clean the rotating bearings 100. After cleaning the bearings 100, the cleaning liquid falls back into the washing liquid area 28 through the opening 34 for reuse. The industrial water purifier 26 is configured to filter out dust particles and spray paint mixed in the cleaning liquid to avoid secondary contamination of the bearings 100.

[0063] During this process, since the cleaning sponge 18 is in contact with the circumferential outer surface of the bearing 100, the cleaning sponge 18 further cleans the dust, stains, etc. on the surface of the bearing 100 under the condition of the self-rotation of the bearing 100, thereby improving the cleaning effect. S4. After the cleaning operation of the bearing 100 is completed, the water pump 2 and the industrial water purifier 26 stop working. The controller controls the solenoid valve on the water pipe 3 to close and the solenoid valve on the air pipe 5 to open. The hair dryer 4 blows hot air through the air pipe 5 into the collection pipe 6, where the gas-liquid dual-purpose nozzle 7 sprays to dry the bearing 100 after cleaning. The exhaust hole 24 on the machine cover is used to relieve pressure. Since the bearing 100 is in a state of self-rotation, the hot air blown by the gas-liquid dual-purpose nozzle 7 can evenly dry the bearing 100, improving the drying effect and efficiency.

[0064] S4. After the drying operation of the bearing 100 is completed after cleaning, the blower 4 stops working, and the spraying device 200 works to evenly spray the rotating bearing 100, thereby completing the spraying operation of the bearing 100.

[0065] S5. After the spraying operation of the bearing 100 is completed, the spraying device 200 stops working, and the hair dryer 4 starts again to blow out hot air through the air pipe 5 into the collecting pipe 6, and the gas-liquid dual-purpose nozzle 7 sprays out to dry the bearing 100 after spraying, completing the drying operation of the bearing 100 after spraying. In conjunction with the rotation of the bearing 100, it is beneficial to the uniform drying of the bearing 100 after spraying.

[0066] S6. After the drying operation of the bearing 100 after spraying is completed, the hair dryer 4 stops working. After a period of time, the box cover 23 is opened to prevent the sudden drop in temperature from affecting the processing quality of the bearing 100. After opening the box cover 23, the belt transmission device 100 continues to work for a period of time so that the bearing 100 keeps rotating, which is conducive to accelerating cooling. After the bearing 100 cools down, since the elastic strip 10 is elastic, the bearing 100 can be directly removed from the base 8 and replaced with the next batch of bearings 100 to be processed.
