Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Specific examples are given below.

[0031] See also Figure 1-8As shown, a brush cleaning machine for the inner ring of a micro bearing comprises a tank body 11; a plate body 12 is slidably connected to the tank body 11; two groups of through grooves are provided on the plate body 12; an annular bracket 13 is fixedly connected to the bottom side of the plate body 12 at positions corresponding to the through grooves; a fixing column 19 is slidably connected to the middle part of the annular bracket 13; the fixing column 19 is inserted into the through groove, and the fixing column 19 is located at the center of the through groove; a group of limit blocks 191 are fixedly connected to the bottom surface of the fixing column 19; a ring body 14 is rotatably connected to the bottom side of the plate body 12 at positions corresponding to the through grooves; the ring body 14 is located in the middle of the annular bracket 13, and the fixing column 19 is located in the middle of the ring body 14; the ring body 14 There are multiple brush plates 18 on it; the installation position of the brush plates 18 is adapted to the position of the raceway of the inner ring of the bearing to be cleaned; the surface of the ring body 14 is fixedly connected to a transmission gear 15; the bottom side of the plate body 12 is rotatably connected to a gear ring 16; the transmission gear 15 and the gear ring 16 are meshed with each other; the two groups of through grooves are respectively located on both sides of the gear ring 16; the through grooves are arranged in a circumferential array; the bottom side of the plate body 12 is fixedly connected to a drive motor 17; the output end of the drive motor 17 is fixedly connected to a drive gear; the drive gear and the gear ring 16 are meshed with each other; a fixing component is provided on the fixing column 19; the fixing component is used to fix the inner ring of the bearing; when in use, the staff will The inner ring of the bearing is placed on the top of the plate body 12, and then the inner ring of the bearing is lowered from the through groove and sleeved on the fixed column 19. The inner ring of the bearing contacts the top side of the limit block 191, and then the inner ring of the bearing is fixed by the fixing assembly. Cleaning liquid is injected into the tank body 11, and the cleaning liquid submerges the plate body 12. Then the drive motor 17 is started. The drive motor 17 is a waterproof servo motor. Then the drive motor 17 drives the drive gear to rotate the gear ring 16. Then the gear ring 16 rotates to drive the transmission gear 15, the ring body 14 and the brush plate 18 to rotate. Then the brush plate 18 rotates to clean the groove of the bearing inner ring. At the same time, the bearing inner ring is immersed in the cleaning liquid, and the rotating brush plate 18 disturbs the cleaning liquid. The surface of the inner ring of the bearing is cleaned to complete the cleaning of the inner ring of the bearing. The raceway of the inner ring of the bearing to be cleaned shall not exceed the cleaning range of 18, otherwise it means that the machine and the bearing are not matched, and a different model of machine needs to be replaced. Relying on the above setting, multiple inner rings of the bearing can be cleaned at one time, and multiple inner rings of the bearing can be isolated and cleaned separately, thereby reducing the situation where the inner rings of the bearing collide with each other during the cleaning process, and further reducing the situation where the surface of the inner ring of the bearing is damaged. At the same time, the raceway outside the inner ring of the bearing is cleaned in a focused manner through the brush plate 18, thereby improving the cleaning effect of the raceway of the inner ring of the bearing and reducing the impact of iron filings adhering to the raceway on the rolling of the bearing balls.

[0032] Further, such as Figure 3 and Figure 5-8As shown, the fixing assembly includes a block 25; a sliding hole is opened in the middle of the fixing column 19; a plurality of sliding grooves are opened on the side of the sliding hole; the block 25 is slidably connected in the sliding groove; a first spring is fixed between the block 25 and the sliding groove; an arc-shaped inclined groove is opened on the side of the block 25 close to the sliding hole; a lower pressure rod 24 is slidably connected in the sliding hole; a push rod 23 is fixed to the bottom end of the push rod 23; a support plate 22 is fixed to the bottom side of the plate body 12 ; An electric push cylinder 21 is fixedly connected between the fixing frame 26 and the support plate 22; the top of the pressing rod 24 is designed in an inverted truncated cone shape; when in use, the inner ring of the bearing is sleeved on the fixing column 19, and then the electric push cylinder 21 is started; the electric push cylinder 21 is a waterproof electric push cylinder 21, and the electric push cylinder 21 is initially in an extended state but not fully extended. The electric push cylinder 21 will contract and drive the support plate 22, the push rod 23 and the pressing rod 24 to move downward, and the bottom of the limit block 191 on the fixing column 19 contacts the annular bracket 13, thereby The downward movement of the lower pressure rod 24 cooperates with the arc-shaped inclined groove to allow the block 25 to extend from the slide groove, so that the block 25 abuts against the inner wall of the bearing inner ring, thereby fixing the bearing inner ring, thereby reducing the rotation of the brush plate 18 and causing the bearing inner ring to rotate under the action of friction, thereby facilitating the brush plate 18 to clean the bearing inner ring. After cleaning, the electric push cylinder 21 is fully extended, thereby driving the support plate 22 and the push rod 23 to push the fixed column 19 upward, so that the fixed column 19 passes through the through groove. The inner ring of the bearing is pushed out to the top of the plate body 12, so that the inner ring of the bearing is easily removed. During the cleaning process, the electric push cylinder 21 can be controlled to reset so that the fixation of the inner ring of the bearing is released, and the brush plate 18 can drive the inner ring of the bearing to rotate. Thereafter, the electric push cylinder 21 is controlled to fix the inner ring of the bearing, so that the cleaning dead angle position of the contact surface between the bottom side of the inner ring of the bearing and the limit block 191 is changed. After fixing again, the cleaning liquid can clean the cleaning dead angle, thereby improving the overall cleaning effect of the inner ring of the bearing.

[0033] Further, such as Figure 6As shown, a cavity 31 is provided inside the ring body 14; a plurality of sliding grooves are provided on the side of the cavity 31 close to the fixed column 19; the brush plate 18 is slidably connected to the inside of the sliding groove and is slidably connected thereto; a return spring 34 is fixedly connected between the side wall of the cavity 31 and the brush plate 18; a fixing piece 32 is rotatably connected to the position corresponding to the brush plate 18 on the inner side wall of the cavity 31; the end of the fixing piece 32 contacts the brush plate 18; a counterweight block 33 is fixedly connected to the side of the fixing piece 32 away from the brush plate 18; the fixing piece 32 is arranged in a V-shaped structure; during the cleaning process, the rotation of the transmission gear 15 will drive the ring body 14 to move The counterweight 33 inside the ring body 14 rotates, thereby driving the counterweight 33 to rotate. Then, under the action of centrifugal force, the counterweight 33 moves away from the center of the ring, so that the end of the fixing plate 32 pushes the brush plate 18 to extend it, so that the brush plate 18 can fit tightly against the inner ring of the bearing. After cleaning, the reset spring 34 pulls the brush plate 18 to slide away from the fixed column 19, thereby driving the counterweight 33 and the fixing plate 32 to reset, relying on the brush plate 18 to move away from the inner ring of the bearing, so that the inner ring of the bearing can be taken out and the inner ring of the bearing can be sleeved on the fixed column 19 and the sliding sleeve 91 can be fixed to the bottom of the column 19.

[0034] Further, such as Figure 2-3 As shown in Figure 5, a submersible pump 41 is fixedly connected to the inner wall of the bottom of the tank body 11; a flexible tube 42 is fixedly connected to the output end of the submersible pump 41; a connecting tube 43 is fixedly connected to the top of the flexible tube 42; a support plate 22 is fixedly connected to the top of the connecting tube 43; a plurality of flushing tubes 45 are fixedly connected to the upper part of the fixed column 19; a hose 44 is fixedly connected to the bottom end of the flushing tube 45; the bottom end of the hose 44 is fixedly connected to the connecting tube 43; a flushing groove is provided on the flushing tube 45; the flushing groove is a trapezoidal groove; during the cleaning process, the submersible pump 41 is started, and then the submersible pump 41 extracts the cleaning liquid in the tank body 11, and then the cleaning liquid is passed through The flexible tube 42, the connecting tube 43 and the hose 44 are injected into each flushing tube 45, and then sprayed out from the flushing groove of the flushing tube 45. The flushing groove is trapezoidal, and the top and bottom of the flushing groove are inclined, so that the sprayed cleaning liquid can be used to wash the top and bottom sides of the inner ring of the bearing at an angle, and at the same time, the inner wall of the inner ring of the bearing is washed. The high-pressure sprayed flushing liquid can improve the cleaning effect of the inner ring of the bearing. During the cleaning process, the electric push rod 23 is controlled to release the fixation of the inner ring of the bearing. After that, the brush plate 18 rotates and can drive the inner ring of the bearing to rotate under the action of friction, so that the sprayed cleaning liquid can fully clean the inner ring of the bearing.

[0035] Further, such as Figure 2-3As shown in Figure 7, a plurality of lifting cylinders 51 are fixedly connected to the bottom side of the fixing frame 26; the lifting cylinders 51 are fixedly connected to the bottom of the tank body 11; a telescopic groove 53 is provided on the side of the block 25 away from the slide hole; a pulley 52 is slidably connected in the telescopic groove 53; a second spring is fixedly connected between the pulley 52 and the telescopic groove 53; in the process of fixing the inner ring of the bearing, the block 25 extends out of the slide groove, and then the pulley 52 will first contact the inner ring of the bearing, and the block 25 continues to squeeze, so that the pulley 52 slides into the telescopic groove 53 and is retracted into the telescopic groove 53, and then the block 25 contacts and fixes the inner wall of the inner ring of the bearing. When the inner ring of the bearing needs to rotate, the electric push is controlled The rod 23 causes the pressing rod 24 to move upward a certain distance, and then causes the block 25 to slide into the slide groove, and the roller fits on the inner wall of the inner ring of the bearing to fix the inner ring of the bearing. When the inner ring of the bearing rotates, the inner ring of the bearing can be positioned to reduce the possibility of sliding during rotation and then colliding with the fixing column 19. After cleaning is completed, the fixing frame 26 is lifted by controlling the lifting cylinder 51, so that the plate body 12 and the inner ring of the bearing move upward to above the liquid level of the cleaning liquid, and then the driving motor 17 is controlled to make the brush plate 18 drive the inner ring of the bearing to rotate, so as to facilitate the removal of the cleaning liquid on the inner ring of the bearing, thereby reducing the waste of resources caused by the residual cleaning liquid on the inner ring of the bearing.

[0036] Further, such as Figure 1-2As shown, the top side of the plate body 12 is fixedly connected with a first guide seat 61 and a second guide seat 62; the cross-sections of the first guide seat 61 and the second guide seat 62 are both trapezoidal in design; the first guide seat 61 is located in the middle of the second guide seat 62; the two groups of through grooves are located between the first guide seat 61 and the second guide seat 62; the middle part of the first guide seat 61 is fixedly connected with a reduction motor 63; the output end of the reduction motor 63 is fixedly connected with a push plate 64; the side of the push plate 64 is fixedly connected with a first arc rod 65 and a second arc rod 66; the middle part of the push plate 64 is V-shaped in design; when in use, the inner ring of the bearing is placed between the first guide seat 61 and the second guide seat 62, and the first guide seat 61 and the second guide seat 62 are used to limit the inner ring of the bearing The range of movement of the ring is adjusted so that it can fall into the through groove, and then the reduction motor 63 is controlled, and the reduction motor 63 drives the push plate 64 to push the inner inner ring, and then the V-shaped structure design in the middle of the push plate 64 can push the bearing inner ring to the through grooves on both sides, so that it falls onto the fixed column 19, which is convenient for the use of the staff. After the bearing inner ring is ejected from the plate body 12, the reduction motor 63 is controlled to drive the push plate 64 to rotate in the opposite direction, and then the first arc rod 65 and the second arc rod 66 are used to lift the bearing inner ring from the bottom side of the bearing inner ring, so that the bottom side of the bearing inner ring slides with the surface of the first arc rod 65 or the second arc rod 66 and moves upward along its surface, so that the bearing inner ring is removed from the fixed column 19, which is convenient for the use of the staff.

[0037] Further, such as Figure 2-3 As shown, a guide cover 71 is fixedly connected to the inner wall of the tank body 11; the guide cover 71 is designed in a truncated cone shape; a filter cartridge 72 is fixedly connected to the middle of the guide cover 71; the guide cover 71 is located at the top of the submersible pump 41; the guide cover 71 is located at the bottom of the fixed frame 26; when in use, the cleaning fluid discharged by the submersible pump 41 will flush the iron filings and foreign matter on the inner ring of the bearing, and then the input end of the submersible pump 41 will generate negative pressure at the top of the guide cover 71, so that these iron filings and foreign matter are gathered to the filter cartridge 72 in the center of the guide cover 71 under the action of the guide cover, so that these iron filings and foreign matter can be collected and filtered centrally, thereby reducing the foreign matter and iron filings in the cleaning fluid from clogging the pipeline, and at the same time reducing the iron filings from scratching the raceway of the inner ring of the bearing.

The screw rod 82 is a ball screw 82. The movement of the screw rod 82 will drive the screw barrel 81 to rotate, and then drive the cleaning brush 83 to rotate. Relying on the rotation of the cleaning brush 83, impurities and iron filings adhering to the inner wall of the filter barrel 72 can be cleaned, thereby reducing the situation where the filter barrel 72 is completely blocked.

[0039] Further, such as Figure 5 and 8 As shown, a plurality of guide rods 92 are fixedly connected to the bottom side of the limit block 191; a plurality of sliding sleeves 91 are fixedly connected to the annular bracket 13; the guide rod 92 passes through the sliding sleeve 91 and is slidably connected thereto; a connecting piece is fixedly connected to the bottom end of the guide rod 92; a fastening spring 93 is fixedly connected between the connecting piece and the bottom side of the annular bracket 13; when in use, the guide rod 92 is set to slide in the middle of the plurality of sliding sleeves 91, so that the guide rod 92, the limit block 191 and the fixed column 19 can be positioned and guided, thereby improving the stability of the fixed column 19 during operation. By setting the fastening spring 93 to pull the guide rod 92, the fixed column 19 can be in the initial state when the lower pressure rod 24 is in the initial state, and the fixed column 19 can be stably fitted on the annular bracket 13, maintaining the stability of the fixed column 19, and facilitating the falling of the bearing inner ring onto the fixed column 19.

[0040] Further, such as Figure 2 and 7 As shown, a rubber ring 101 is fixedly connected to the side of the block 25 away from the sliding hole; the pulley 52 is located in the middle of the rubber ring 101; a buffer rubber pad 102 is fixedly connected to the top side of the plate body 12; when in use, by providing the rubber ring 101, the friction between the block 25 and the inner side wall of the bearing inner ring can be increased, thereby improving the fixing effect of the bearing inner ring and reducing the indentation caused by the squeezing of the block 25 on the bearing inner ring. By providing the annular rubber pad, the bearing inner ring can be protected, reducing the dents and scratches caused by the collision between the bearing inner ring and the plate body 12 when the bearing inner ring is placed and when the bearing inner ring is removed from the fixing column 19.

[0041] Working principle: when in use, the staff places the processed bearing inner ring on the top of the plate body 12, and then lowers the bearing inner ring from the through groove to the fixed column 19, and the bearing inner ring contacts the top side of the limit block 191, and then starts the electric push cylinder 21; the electric push cylinder 21 is a waterproof electric push cylinder 21, and the electric push cylinder 21 is initially in an extended state but not fully extended. The electric push cylinder 21 will contract and drive the support plate 22, the push rod 23 and the lower pressure rod 24 to move downward, and the bottom of the limit block 191 on the fixed column 19 contacts the annular bracket 13, so that the downward movement of the lower pressure rod 24 cooperates with the arc-shaped inclined groove to make the block 25 extend from the slide groove, so that the block 25 presses against the inner wall of the bearing inner ring, thereby fixing the bearing inner ring, and the tank body 11 A cleaning liquid is injected, and the cleaning liquid covers the plate body 12. Then the drive motor 17 is started. The drive motor 17 is a waterproof servo motor. Then the drive motor 17 drives the drive gear to rotate the gear ring 16. Then the gear ring 16 rotates to drive the transmission gear 15, the ring body 14 and the brush plate 18 to rotate. Then the brush plate 18 rotates to clean the groove of the bearing inner ring. At the same time, the bearing inner ring is immersed in the cleaning liquid. The rotating brush plate 18 disturbs the cleaning liquid to clean the surface of the bearing inner ring, thereby completing the cleaning of the bearing inner ring. Relying on the above arrangement, multiple bearing inner rings can be cleaned at one time, and multiple bearing inner rings can be isolated and cleaned separately, thereby reducing the collision of the bearing inner rings during the cleaning process. This will reduce the damage to the surface of the inner ring of the bearing, and at the same time, the raceway outside the inner ring of the bearing is cleaned in a focused manner through the brush plate 18, thereby improving the cleaning effect of the raceway of the inner ring of the bearing and reducing the impact of iron filings adhering to the raceway on the rolling of the bearing balls. During the cleaning process, the rotation of the transmission gear 15 will drive the ring body 14 to rotate, and then drive the counterweight block 33 inside the ring body 14 to rotate. Then, under the action of centrifugal force, the counterweight block 33 moves away from the center of the ring, and the end of the fixing plate 32 will push the brush plate 18 to extend it, so that the brush plate 18 can fit closely with the inner ring of the bearing, and after cleaning is completed, the return spring 34 will pull the brush plate 18 to slide away from the fixing column 19 , and then drive the counterweight block 33 and the fixing plate 32 to reset, relying on the brush plate 18 to move away from the inner ring of the bearing, so that the inner ring of the bearing can be taken out and the inner ring of the bearing is sleeved on the fixing column 19 and the sliding sleeve 91 fixes the bottom of the column 19, start the submersible pump 41, and then the submersible pump 41 extracts the cleaning liquid in the tank body 11, and then injects the cleaning liquid into each flushing pipe 45 through the flexible pipe 42, the connecting pipe 43 and the hose 44, and then sprays it from the flushing groove of the flushing pipe 45. The flushing groove is trapezoidal, and the top and bottom of the flushing groove are inclined, so that the sprayed cleaning liquid washes the top and bottom sides of the bearing inner ring obliquely, and at the same time washes the inner wall of the bearing inner ring, relying on the high-pressure spraying of the flushing liquid, so as to improve the cleaning effect of the bearing inner ring. During the cleaning process,The electric push rod 23 is controlled to release the fixation of the inner ring of the bearing, and then the brush plate 18 rotates to drive the inner ring of the bearing to rotate under the action of friction, so that the sprayed cleaning liquid can fully clean the inner ring of the bearing. In the process of fixing the inner ring of the bearing, the block 25 extends out of the slide groove, and then the pulley 52 will first contact the inner ring of the bearing, and the block 25 continues to squeeze, so that the pulley 52 slides into the telescopic groove 53 and is retracted into the telescopic groove 53. Then the block 25 contacts and fixes the inner side wall of the inner ring of the bearing. When the inner ring of the bearing needs to rotate, the electric push rod 23 is controlled to make the lower pressure rod 24 move upward a certain distance, and then the block 25 slides into the slide groove, and the roller fits on the inner side wall of the inner ring of the bearing to clean the inner ring of the bearing. Fixed, when the inner ring of the bearing rotates, the inner ring of the bearing can be positioned to reduce the sliding during the rotation and the collision with the fixed column 19. After the cleaning is completed, the fixing frame 26 is lifted by controlling the lifting cylinder 51, so that the plate body 12 and the inner ring of the bearing are moved upward to above the liquid level of the cleaning liquid. Then, the driving motor 17 is controlled to make the brush plate 18 drive the inner ring of the bearing to rotate, so as to facilitate the cleaning liquid on the inner ring of the bearing to be thrown out, thereby reducing the waste of resources caused by a large amount of cleaning liquid remaining on the inner ring of the bearing. The inner ring of the bearing is placed between the first guide seat 61 and the second guide seat 62. The first guide seat 61 and the second guide seat 62 are used to limit the range of movement of the inner ring of the bearing so that it can fall into the through groove, and then through Control the reduction motor 63, and the reduction motor 63 drives the push plate 64 to push the inner inner ring. Then, the V-shaped structure design in the middle of the push plate 64 can push the inner ring of the bearing to the through grooves on both sides, so that it falls onto the fixed column 19, which is convenient for the use of the staff. After the inner ring of the bearing is ejected from the plate body 12, the reduction motor 63 is controlled to drive the push plate 64 to rotate in the opposite direction. Then, the inner ring of the bearing is lifted up from the bottom side of the inner ring of the bearing through the first arc rod 65 and the second arc rod 66, so that the bottom side slides with the surface of the first arc rod 65 or the second arc rod 66 and moves upward along its surface, so that the inner ring of the bearing is removed from the fixed column 19, which is convenient for the use of the staff. When in use, the cleaning fluid discharged by the submersible pump 41 will flush the shaft The iron filings and foreign matter on the bearing inner ring will be sucked by the input end of the submersible pump 41 to generate negative pressure at the top of the guide cover 71, so that these iron filings and foreign matter will be gathered under the action of the guide cover to the filter cylinder 72 in the center of the guide cover 71, so that these iron filings and foreign matter can be collected and filtered centrally, reducing the blockage of the pipe by foreign matter and iron filings in the cleaning liquid, and reducing the scratching of the raceway of the bearing inner ring by iron filings. When in use, the upward movement of the fixing frame 26 will pull the screw rod 82 to move upward, and the screw rod 82 is a ball screw rod 82. The movement of the screw rod 82 will drive the screw barrel 81 to rotate, and then drive the cleaning brush 83 to rotate. Relying on the rotation of the cleaning brush 83, the impurities and iron filings adhering to the inner wall of the filter cylinder 72 can be cleaned.This reduces the possibility of the filter cartridge 72 being completely blocked;

[0042] By setting a guide rod 92 to slide in the middle of multiple sliding sleeves 91, the guide rod 92, the limit block 191 and the fixed column 19 can be positioned and guided, thereby improving the stability of the fixed column 19 during operation. By setting a fastening spring 93 to pull the guide rod 92, the fixed column 19 can be in the initial state when the lower pressure rod 24 is in the fixed column 19. The fixed column 19 can be stably fitted on the annular bracket 13 to maintain the stability of the fixed column 19, which is convenient for the bearing inner ring to fall and be sleeved on the fixed column 19. By setting a rubber ring 101, the friction between the block 25 and the inner side wall of the bearing inner ring can be increased, thereby improving the fixing effect of the bearing inner ring and reducing the indentation caused by the squeezing of the block 25 on the bearing inner ring. By setting an annular rubber pad, the bearing inner ring can be protected, reducing the dents and scratches caused by the collision between the bearing inner ring and the plate body 12 when the bearing inner ring is placed and when the bearing inner ring is removed from the fixed column 19.
