Description

Technical Field

[0001] This invention relates to a bearing ring cleaning device and cleaning method, which is used in bearing production and processing and belongs to the field of bearing processing technology. Background Technology

[0002] After grinding, heat treatment, and other processing steps, bearing raceways accumulate contaminants such as cutting fluid, oil, metal particles, and polishing paste on their surfaces. Conventional spraying or soaking methods are insufficient for effectively cleaning the inner and outer walls, raceways, and end faces of the raceways, leaving cleaning dead zones. Cleaning different surfaces requires step-by-step procedures or manual adjustments, resulting in low efficiency and inadequate drying after cleaning, leading to residual water stains. Even when using equipment for cleaning, fixed-structure brushing devices are difficult to adapt to bearing raceways of different sizes and specifications. Therefore, we propose a bearing raceway cleaning device for bearing manufacturing and processing to solve the above problems. Summary of the Invention

[0003] In view of the technical problems existing in the prior art, the purpose of the present invention is to provide a bearing ring cleaning device and cleaning method to solve the problems of dead corners, low degree of automation and poor adaptability to different sizes in the prior art, and to achieve comprehensive and efficient cleaning of the inner and outer walls and end faces of the bearing rings.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a bearing ring cleaning device, including a workbench, a mounting frame detachably mounted on the upper surface of one side of the workbench, a pneumatic device mounted at the top of the mounting frame, a mounting cover connected to the bottom of the pneumatic device, and a power device installed inside the mounting cover; the output shaft of the power device is connected to a top rotating structure, the top rotating structure being provided with circumferentially distributed L-shaped brush units, each L-shaped brush unit comprising multiple independent L-shaped brushes evenly spaced circumferentially; a plug rod is connected to the lower part of the top rotating structure located in the middle of the multiple independent L-shaped brushes, and the plug rod is engaged with the bottom rotating structure; an annular water tank is formed downwards on the surface of the workbench, and the bottom rotating structure is rotatably mounted at the bottom of the annular water tank; a rinsing mechanism is provided on the upper workbench along the annular water tank, and the bottom of the annular water tank is connected to a drainage system via a water pipe; Furthermore, the pneumatic device is a cylinder; Furthermore, the power unit is a drive motor; Furthermore, the top of the mounting cover is connected to the cylinder via a flange connection, and guide rods are connected to both sides of the top of the mounting cover. One end of the guide rod passes through the mounting frame and extends to the top of the mounting frame. Furthermore, multiple independent L-shaped brushes of the L-shaped brush unit are integrated around a mounting plate via their respective L-shaped rods; the number of L-shaped brushes is four, and every two are distributed opposite each other around the perimeter of the mounting plate. Furthermore, the L-shaped rod is telescopically mounted inside the mounting plate, and the mounting plate has an axially opened channel for the L-shaped rod to extend into. One end of the L-shaped rod extends into the channel. Bolts are provided on the surface of the L-shaped rod, and the bolts are rotatably connected to the mounting plate. Furthermore, each individual L-shaped brush is formed by a horizontal part and a vertical part. The lower surface of the horizontal part and the inner surface of the vertical part are covered with bristles. The outer wall of the vertical part of each individual L-shaped brush is fixed to the other end of the L-shaped rod by screws. The horizontal part and the vertical part of each individual L-shaped brush are both formed with an arc design that matches the outer diameter of the bearing ring. Furthermore, the bottom of the mounting bracket is slidably connected to the worktable by a slide rail set on the upper edge of the worktable surface, allowing the mounting bracket to slide horizontally relative to the worktable. Furthermore, limit blocks are respectively provided at both ends of the slide rail located at the edge of the working surface; Furthermore, the rinsing mechanism includes: an annular water pipe arranged along the edge of the annular water tank and a water inlet pipe connected to the annular water pipe, one end of the water inlet pipe being connected to an external water source via a water pump, and several flexible rinsing pipes being evenly spaced around the top of the annular water pipe.

[0005] Furthermore, the bottom rotating structure includes a rotating shaft, a support plate, a brush unit, a support plate roller assembly, and a bearing ring roller assembly. A support plate integrated with the rotating shaft is provided in the lower region of the rotating shaft. The bottom of the rotating shaft forms a protrusion relative to the lower end face of the support plate. The outer edge of the lower end face of the support plate corresponds to the upper surface of the water tank bottom, where the support plate roller assembly is located. The lower end face of the support plate abuts against the support plate roller assembly, allowing the support plate to rotate. A retractable brush unit is provided in the upper region of the rotating shaft. A bearing ring roller assembly is located at the outer edge of the upper end face of the support plate. The bearing ring is fitted around the brush unit of the rotating shaft and abuts against the bearing ring roller assembly through its lower end face, allowing the ring to rotate. A slot is provided on the upper end face of the rotating shaft to mate with a rod in the top rotating structure. During installation, the rod is inserted into the slot of the rotating shaft. Furthermore, the protrusion at the bottom of the rotating shaft has a groove on the bottom surface of the annular water tank that matches the protrusion, and the protrusion is inserted into the groove. Furthermore, limit strips are connected to both sides of the insertion rod surface. The limit strip consists of a long strip and a triangular block. The triangular block is connected to the bottom of the long strip. The slot of the rotating shaft is provided with limit grooves that are adapted to the limit strip at equal intervals. The top of the limit groove is open outward, which makes it easy for the triangular block to move along the limit groove into the limit groove, and makes it easy for the insertion rod to drive the rotating shaft to rotate. Furthermore, the retractable brush unit includes four sets of brushes, which are equally spaced around the outer periphery of the rotating shaft via a telescopic mechanism. The brushes are mounted on the telescopic mechanism with the bristles facing outwards. Furthermore, the bottom surface of the annular water tank has a circular arc-shaped groove around its edge, and the bottom of the arc-shaped groove is connected to an external drainage tank via a water pipe, and the drainage tank is equipped with a drain valve.

[0006] The cleaning method for bearing rings is as follows: (1) Installation of the cleaning device; a. First, install the bottom rotating structure inside the water tank. During installation, make sure that the rotating shaft of the bottom rotating structure is fitted into the assembly groove (recess) on the bottom surface of the water tank; and the lower end face of the support plate of the bottom rotating structure contacts the support plate roller group set on the bottom surface of the water tank, so that the support plate can rotate relative to the water tank through the roller group. b. Place the bearing rings (large bearings) on the bearing ring roller assembly on the support plate of the bottom rotating structure by hoisting, and put them on the outside of the brush unit on the upper part of the rotating shaft; c. Adjust the brush to the appropriate position using the telescopic mechanism according to the inner diameter of the bearing ring; d. Adjust the top rotating mechanism horizontally on the worktable to position it above the bearing ring, so that the top rotating structure moves downward through the pneumatic device to assemble with the bottom rotating structure; complete the assembly of the cleaning device and the bearing ring. After the above assembly is completed, the L-shaped brush in the top rotating structure contacts the upper end face and outer diameter of the bearing ring, and the brush on the upper part of the bottom rotating structure shaft contacts the inner diameter of the bearing ring. (2) Flushing of bearing rings; a. Open the rinsing mechanism, and the several rinsing pipes of the annular water pipe will spray water onto the bearing race; start the motor, and the motor shaft will rotate, causing the mounting plate in the top rotating structure to rotate. Since the insert rod below the mounting plate is inserted into the slot of the rotating shaft of the bottom rotating structure, it will drive the entire bottom rotating structure to rotate synchronously. During the above rotation, the synchronous rotation of the top and bottom rotating structures driven by the motor will first be forward and then reverse, alternating between forward and reverse rotation. The randomness generated by the forward and reverse rotation will ensure the cleanliness of the bearing race. The rotation of the mounting plate drives the L-shaped brush to rotate, which brushes the outer diameter and upper surface of the bearing ring. The rotating shaft of the bottom rotating structure rotates, and the brush on the shaft brushes the inner diameter of the bearing ring simultaneously. b. After the above brushing is completed, turn off the motor and the rinsing mechanism; start the pneumatic device to move upward, so that the top rotating structure is separated from the bottom rotating structure and moves to the side of the worktable to avoid it, and flip the bearing ring up and down; repeat step d in the installation of the above cleaning device, and then perform step a of rinsing the bearing ring, so as to thoroughly brush the bearing ring and avoid incomplete cleaning of the bearing ring.

[0007] Based on the further technical concept of the cleaning method described above, the cleaning method for bearing rings can be an immersion method by filling a water tank with water, that is, rinsing first, followed by immersion; the specific cleaning steps are as follows: First, open the drain valve of the drain tank and rinse the bearing rings according to the rinsing method. The rinsing time is 3-5 minutes to complete the rinsing of the iron filings from the bearing rings. Then, drain the water used to rinse the iron filings out of the tank. The rinsing mechanism continues to flush; once the water tank is full, close the drain valve of the drain tank. At this time, the bearing rings are immersed in the water tank, and the motor continues to rotate during this immersion process; after immersion for 3-5 minutes, open the drain valve of the drain tank to drain the water. During the drainage process, the flushing mechanism continues to flush, adjusting the opening of the drain valve to ensure that the speed of the drain outlet is greater than the speed of the flushing water inlet; after flushing for 5 minutes, the water flow balance is achieved; the drain valve is then closed, completing the cleaning of the bearing rings.

[0008] After cleaning the bearing rings using the two cleaning modes mentioned above, the bearing rings are dried by spraying gas using an air jet device. The jet treatment is performed manually using high-pressure air. Alternatively, the jet device can be placed on the workbench of the cleaning device or directly connected to the flushing pipe of the flushing mechanism. The air source can be switched using a valve. Finally, the motor is turned off and rotation is stopped. The top rotating structure is moved to one side of the workbench to avoid obstruction. The bearing rings that have been dried by jet are then lifted out of the water tank by hoisting, completing the bearing cleaning work.

[0009] The beneficial effects of this invention are: This solution utilizes the interlocking connection between a top rotating structure and a bottom rotating structure, which rotate synchronously via a power unit. This causes the brushes in both structures to rotate, providing a comprehensive and synchronized cleaning of the bearing races. Simultaneously, the power unit controls the alternating forward and reverse rotation of the bearing races. The randomness generated by these rotations ensures the cleanliness of the bearing races and prevents incomplete cleaning due to dead zones on the inner and outer walls of the bearing races.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] Example 1 like Figure 1-8The bearing ring cleaning device shown includes a workbench 1. A mounting frame 2 is detachably mounted on the upper surface of one side of the workbench 1. A pneumatic device is mounted at the top of the mounting frame 2, and a mounting cover 3 is connected to the bottom of the pneumatic device. A power device is installed inside the mounting cover 3. The output shaft of the power device is connected to a top rotating structure. The top rotating structure is equipped with a circumferentially distributed L-shaped brush unit, which includes multiple independent L-shaped brushes 4 evenly distributed circumferentially. A plug rod 5 is connected to the lower part of the top rotating structure located in the middle of the multiple independent L-shaped brushes 4, and the plug rod 5 is inserted into the bottom rotating structure. An annular water tank 6 is formed on the downward-facing surface of the workbench 1, and the bottom rotating structure is rotatably mounted at the bottom of the annular water tank 6. A rinsing mechanism is provided on the workbench 1 along the annular water tank 6, and the bottom of the annular water tank 6 is connected to a drainage system through a water pipe 7. Furthermore, the rinsing mechanism is connected to an external water source, and the bearing ring 30 is placed in the annular water tank 6 and placed on the bottom rotating structure; Furthermore, the pneumatic device uses cylinder 8, which is an SC cylinder; Furthermore, the power unit adopts a drive motor 9, which is a three-phase asynchronous motor or a single-phase asynchronous motor capable of forward and reverse rotation.

[0021] Furthermore, the top of the mounting cover 3 is connected to the cylinder 8 via a flange connection, and guide rods 10 are connected to both sides of the top of the mounting cover 3. One end of the guide rod 10 passes through the mounting frame 2 and extends to the top of the mounting frame 2. Furthermore, multiple independent L-shaped brushes 4 of the L-shaped brush unit are integrated around a mounting plate 12 by their respective L-shaped rods 11; there are four L-shaped brushes 4, and each pair is distributed around the mounting plate 12 in opposite directions. Furthermore, the L-shaped rod 11 is telescopically disposed within the mounting plate 12, and the mounting plate 12 has an axially formed channel for the L-shaped rod 11 to extend into. One end of the L-shaped rod 11 extends into the channel. Bolts 13 are provided on the surface of the L-shaped rod 11. When it is necessary to brush the bearing rings 30, which are larger or smaller in size, the bolts 13 are rotated to loosen them, thereby releasing the fixation of the L-shaped rod 11 and allowing the L-shaped brush 4 to be adjusted. The bolts 13 are rotatably connected to the mounting plate 12. Furthermore, each independent L-shaped brush 4 is formed by a horizontal part 4.1 and a vertical part 4.2. The lower surface of the horizontal part 4.1 and the inner surface of the vertical part 4.2 are covered with bristles. The outer wall of the vertical part 4.2 of each independent L-shaped brush 4 is fixed to the other end of the L-shaped rod 11 by screws 14. The horizontal part 4.1 and the vertical part 4.2 of each independent L-shaped brush 4 are formed with an arc design that matches the outer diameter arc of the bearing ring 30. This arc design allows the brush 4 to conform to the bearing ring 30 during cleaning.

[0022] Furthermore, the bottom of the mounting frame 2 is slidably connected to the worktable 1 by a slide rail 15 set on the edge of the upper surface of the worktable 1, so that the mounting frame 2 can slide horizontally relative to the worktable 1, thereby driving the top rotating structure to move and adjust its position on the worktable 1; for avoidance when placing or removing workpieces in the cleaning device. Furthermore, limit blocks 16 are respectively provided at both ends of the slide 15 located on the edge of the upper surface of the workbench 1, which are used to limit the movement of the mounting frame 2 on the workbench 1 to the required position, so as to prevent the mounting frame 2 from moving too far.

[0023] Furthermore, the rinsing mechanism includes: an annular water pipe 17 arranged along the edge of the annular water tank 6 and a water inlet pipe 18 connected to the annular water pipe 17. One end of the water inlet pipe 18 is connected to an external water source through a water pump. Several flexible rinsing pipes 19 are evenly arranged around the top of the annular water pipe 17 at equal intervals.

[0024] Optionally, the number of flushing tubes 19 is set to seven.

[0025] Furthermore, the bottom rotating structure includes a rotating shaft 20, a support plate 21, a brush unit, a support plate roller assembly 22, and a bearing ring roller assembly 23. A support plate 21, integral with the rotating shaft 20, is provided in the lower region of the rotating shaft 20. A protrusion 20.1 is formed at the bottom of the rotating shaft 20 relative to the lower end face of the support plate 21. The outer edge of the lower end face of the support plate 21 corresponds to the upper surface of the bottom of the water tank 6, where the support plate roller assembly 22 is provided. The lower end face of the support plate 21 abuts against the support plate roller assembly 22, allowing the support plate 21 to... Rotation; a retractable brush unit is provided in the upper part of the rotating shaft 20, and a bearing ring roller assembly 23 is provided at the outer edge of the upper end face of the support plate 21. The bearing ring 30 is sleeved on the outside of the brush unit of the rotating shaft 20 and abuts against the bearing ring roller assembly 23 through the lower end face of the bearing ring, so that the ring 30 can rotate; the upper end face of the rotating shaft 20 is provided with a slot 20.2 that cooperates with the insertion rod 5 in the top rotating structure. During installation, the insertion rod 5 is inserted into the slot 20.1 of the rotating shaft 20. Furthermore, the protrusion 20.1 at the bottom of the rotating shaft 20 has a groove on the bottom surface of the annular water tank 6 that matches the protrusion 20.1. The protrusion 20.1 is inserted into the groove to prevent the rotating shaft 20 from deviating during rotation. Furthermore, limit strips are connected to both sides of the surface of the insertion rod 5. The limit strips are composed of a long strip 5.1 and a triangular block. The triangular block is connected to the bottom of the long strip 5.1. The slot 20.1 of the rotating shaft 20 is provided with limit grooves that are adapted to the limit strips at equal intervals. The top of the limit groove is open outward, so that the triangular block can move along the limit groove into the limit groove, and the insertion rod 5 can drive the rotating shaft 20 to rotate. Furthermore, the retractable brush unit includes four sets of brushes 21, which are equally spaced around the outer periphery of the rotating shaft 20 via a telescopic mechanism. The brushes 24 are mounted on the telescopic mechanism with the bristles facing outward. When it is necessary to brush the inner wall of the bearing ring 30, which is larger or smaller, the position of the brushes 24 can be adjusted by adjusting the telescopic mechanism so that the bristles fit against the inner wall of the bearing ring 30.

[0026] Optionally, the telescopic mechanism comprises a cylinder 25, a rod 26, and a limiting block 27. The rod 26 is slidably disposed inside the cylinder 25, and the limiting block is rotatably connected to the top of the cylinder 25. The surface of the rod 26 is provided with equally spaced slots for inserting a plug on the limiting block. When the plug is inserted into the slot, the telescopic adjustment of the cylinder 25 and the rod 26 can be locked. When it is necessary to clean the inner wall of the bearing ring 30, which is either large or small, the tail of the limiting block is pressed down to disengage the limiting block from the slot, thereby adjusting the position of the rod 26 inside the cylinder 25.

[0027] In this design, in order to reduce the flow of water from the annular water tank 6 into the groove corresponding to the shaft protrusion 20.1, an arc-shaped groove 28 is formed around the edge of the bottom surface of the annular water tank 6. The bottom of the arc-shaped groove 28 is connected to the external drainage tank 29 through a water pipe 7, and the drainage tank 29 is equipped with a drain valve.

[0028] Furthermore, the number of the support plate roller group 22 and the bearing ring roller group 23 is set to four, and they are distributed at equal intervals on the bottom surface of the water tank 6 and the upper surface of the support plate 21, respectively.

[0029] The cleaning method for bearing rings is as follows: (1) Installation of the cleaning device; a. First, install the bottom rotating structure into the water tank 6. During installation, make the rotating shaft 20 of the bottom rotating structure fit into the assembly groove (recess) on the bottom surface of the water tank 6. Furthermore, the lower end face of the support plate 21 of the bottom rotating structure contacts the support plate roller group 22 provided on the bottom surface of the water tank 6, so that the support plate 21 can rotate relative to the water tank 6 through the roller group 22. b. The bearing ring 30 (large bearing) is placed on the bearing ring roller assembly 23 on the support plate 21 of the bottom rotating structure by hoisting, and is fitted over the brush unit on the upper part of the rotating shaft 20. c. Adjust the brush 24 to the appropriate position using the telescopic mechanism according to the inner diameter of the bearing ring 30. d. Adjust the top rotating mechanism horizontally on the worktable 1 to above the bearing ring 30, so that the top rotating structure moves downward through the pneumatic device and assembles with the bottom rotating structure; complete the assembly of the cleaning device and the bearing ring 30. After the above assembly is completed, the L-shaped brush 4 in the top rotating structure contacts the upper end face and outer diameter of the bearing ring 30, and the brush 24 on the upper part of the rotating shaft 20 of the bottom rotating structure contacts the inner diameter of the bearing ring 30. (2) Flushing of bearing rings; a. Open the rinsing mechanism, and spray water from several rinsing pipes 19 of the annular water pipe 17 onto the bearing ring 30; start the motor 9, and the rotation of the motor shaft drives the mounting plate 12 in the top rotating structure to rotate. Since the insert 5 below the mounting plate 12 is inserted into the slot 20.1 of the rotating shaft 20 of the bottom rotating structure, the entire bottom rotating structure is driven to rotate synchronously; during the above rotation, the synchronous rotation process of the top rotating structure and the bottom rotating structure driven by the motor 9 is to first rotate forward and then rotate in reverse alternately. The randomness generated by the forward and reverse rotation ensures the cleanliness of the bearing ring 30. The rotation of the mounting plate 12 drives the L-shaped brush 4 to rotate, which brushes the outer diameter and upper end face of the bearing ring 30. The rotating shaft 20 of the bottom rotating structure rotates, and the brush 24 on the rotating shaft 20 brushes the inner diameter of the bearing ring 30 simultaneously. b. After the above brushing is completed, turn off motor 9 and the rinsing mechanism; start the pneumatic device to move upward, so that the top rotating structure is separated from the bottom rotating structure and moves to the side of the workbench 1 to avoid it, and flip the bearing ring 30 up and down; repeat step d in the installation of the above cleaning device, and then perform step a of rinsing the bearing ring, so as to thoroughly brush the bearing ring 30 and avoid incomplete cleaning of the bearing ring 30.

[0030] The cleaning method for the bearing rings 30 described above is a rinsing method. In this rinsing process, the water spraying mechanism continuously sprays water, and the power mechanism is always on. It should be noted that the drain valve on the drain pipe of the drain trough 29 at the bottom of the water tank 6 remains open throughout the rinsing process, and the water in the water tank 6 is in a flowing state.

[0031] Example 2 The structure of the cleaning device in this embodiment 2 is exactly the same as that in embodiment 1, the difference being the cleaning method. Based on a further technical concept of the cleaning method in Embodiment 1, the cleaning method for the bearing ring 30 in this embodiment can be an immersion method by filling a water tank with water, that is, rinsing first and then immersing; the specific cleaning steps are as follows: First, open the drain valve of the drain tank 29 and rinse the bearing ring 30 according to the rinsing method. The rinsing time is 3-5 minutes to complete the rinsing of the iron filings on the bearing ring 30. Then, drain the water used to rinse the iron filings to the outside of the water tank 6. The rinsing mechanism continues to rinse; after the water tank 6 is full, the drain valve of the drain tank 29 is closed. At this time, the bearing ring 30 is immersed in the water tank 6. During this immersion process, the motor 9 continues to rotate; after immersion for 3-5 minutes, the drain valve of the drain tank 29 is opened to drain the water. During the drainage process, the flushing mechanism continues to flush, adjusting the opening of the drain valve to ensure that the speed of the drain outlet is greater than the speed of the flushing water inlet; after flushing for 5 minutes, the water flow balance is achieved; the drain valve is then closed, completing the cleaning of the bearing ring 30.

[0032] After cleaning the bearing rings 30 using the above two cleaning modes, the bearing rings 30 are dried by spraying gas using an air jet device. The jet treatment is carried out manually using high-pressure air. Alternatively, the jet device can be placed on the workbench 1 of the cleaning device or directly connected to the flushing pipe 19 of the flushing mechanism. The air source can be switched by a valve. Finally, the motor 9 is turned off and stopped rotating. The top rotating structure is moved to one side of the workbench 1 to avoid obstruction. The bearing ring 30, which has been dried by jet, is lifted out of the water tank 6 by hoisting, thus completing the bearing cleaning work.

7. The bearing ring cleaning device according to claim 6, characterized in that: Limiting strips are connected to both sides of the insertion rod surface. The limiting strip consists of a long strip and a triangular block. The triangular block is connected to the bottom of the long strip. The slot of the rotating shaft is provided with limiting grooves that are adapted to the limiting strip at equal intervals. The top of the limiting groove is open to the outside, so that the triangular block can move along the limiting groove into the limiting groove, and the insertion rod can drive the rotating shaft to rotate.

8. The bearing ring cleaning device according to claim 6, characterized in that: The retractable brush unit includes four sets of brushes, which are evenly spaced around the outer periphery of the rotating shaft via a telescopic mechanism. The brushes are mounted on the telescopic mechanism with the bristles facing outwards.

9. The bearing ring cleaning device according to claim 1, characterized in that: The bottom surface of the annular water tank has a circular arc-shaped groove around its edge. The bottom of the arc-shaped groove is connected to an external drainage tank via a water pipe, and the drainage tank is equipped with a drain valve.

10. A method for cleaning bearing rings using the cleaning apparatus described in any one of claims 1-9, characterized in that, The steps are as follows: (1) Installation of the cleaning device; a. First, install the bottom rotating structure inside the water tank. During installation, make sure that the rotating shaft of the bottom rotating structure is fitted into the groove on the bottom surface of the water tank; and the lower end face of the support plate of the bottom rotating structure contacts the support plate roller group set on the bottom surface of the water tank, so that the support plate can rotate relative to the water tank through the roller group. b. Place the bearing rings on the bearing ring roller assembly on the support plate of the bottom rotating structure by means of hoisting, and put them on the outside of the brush unit on the upper part of the rotating shaft; c. Adjust the brush to the appropriate position using the telescopic mechanism according to the inner diameter of the bearing ring; d. Adjust the top rotating mechanism horizontally on the worktable to position it above the bearing ring, so that the top rotating structure moves downward through the pneumatic device to assemble with the bottom rotating structure; complete the assembly of the cleaning device and the bearing ring. After the above assembly is completed, the L-shaped brush in the top rotating structure contacts the upper end face and outer diameter of the bearing ring, and the brush on the upper part of the bottom rotating structure shaft contacts the inner diameter of the bearing ring. (2) Flushing of bearing rings; a. Open the rinsing mechanism, and the several rinsing pipes of the annular water pipe will spray water onto the bearing race; start the motor, and the motor shaft will rotate, causing the mounting plate in the top rotating structure to rotate. Since the insert rod below the mounting plate is inserted into the slot of the rotating shaft of the bottom rotating structure, it will drive the entire bottom rotating structure to rotate synchronously. During the above rotation, the synchronous rotation of the top and bottom rotating structures driven by the motor will first be forward and then reverse, alternating between forward and reverse rotation. The randomness generated by the forward and reverse rotation will ensure the cleanliness of the bearing race. The rotation of the mounting plate drives the L-shaped brush to rotate, which brushes the outer diameter and upper surface of the bearing ring. The rotating shaft of the bottom rotating structure rotates, and the brush on the shaft brushes the inner diameter of the bearing ring simultaneously. b. After the above scrubbing is completed, turn off the motor and the rinsing mechanism; Start the pneumatic device to move upwards, allowing the top rotating structure to detach from the bottom rotating structure and move to the side of the worktable to avoid it, thus flipping the bearing rings up and down; then repeat step d in the installation of the cleaning device above, and then perform step a of rinsing the bearing rings, thereby thoroughly cleaning the bearing rings.
