Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a grinding device for the inner surface of bearing rings used in bearing processing and manufacturing. Background Technology

[0002] Existing bearing ring inner surface grinding devices used in bearing manufacturing face difficulties in removing impurities during actual grinding processes. The narrow, enclosed space within the bearing ring's inner bore obstructs the grinding area when the grinding wheel extends inside, causing a large amount of metal shavings and fine grinding powder to accumulate in the blind areas of the bearing's inner bore. To reduce grinding temperature and wear, existing equipment commonly uses a spray cooling liquid to cool the processing area. However, this often results in impurities mixing with the cooling liquid to form wet debris that adheres tightly to the inner bore wall. Traditional dust extraction and blowing methods are susceptible to damage from the grinding wheel. Due to obstruction and water mist, it is impossible to effectively clean adhesive wet metal impurities. Simply rinsing with cooling liquid is not only incomplete but also easily causes impurities to accumulate, making it impossible to achieve simultaneous cleaning after processing. After processing, a large amount of impurities remain in the inner hole of the bearing ring, requiring manual secondary wiping to ensure the cleanliness of the workpiece. This significantly increases the processing steps and workload, reduces processing efficiency, and manual cleaning is prone to incomplete cleaning and scratches on the workpiece, making it difficult to meet the high-precision, automated grinding processing requirements of the inner surface of the bearing ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The positioning fixture drives the bearing ring to rotate, which is then processed in conjunction with the grinding fixture. The grinding fixture controls the contact surface between the grinding wheel and the bearing ring. After the grinding wheel completes the grinding operation on the inner wall of the bearing ring, it retracts from the inside of the bearing ring. At this time, the electric actuator controls the connecting part to drive the connecting rod to slide inside the circular groove. The connecting rod pushes out the magnetic block and extends it into the inside of the bearing ring. The magnetic force of the magnetic block adsorbs the iron filings and impurities generated inside the bearing ring onto its surface. Then the electric actuator pulls the magnetic block out, thus solving the problems of wet iron filings being difficult to clean and the cooling liquid easily washing the grinding debris into the dead corner of the inner hole, causing accumulation. The magnetic block driven by the connecting rod is not affected by water mist or waste liquid and can directly adsorb fine metal grinding debris in both dry and wet states, accurately cleaning the residual impurities on the inner wall, reducing subsequent manual cleaning processes, and avoiding collision damage during workpiece transportation. After the magnetic block completes adsorption, it retracts into the magnetic shielding sleeve. At the same time, the scraper ring scrapes off the impurities attached to the surface of the magnetic block, achieving self-cleaning of the magnetic block.

[0015] 2. After the magnetic block is completely retracted into the magnetic shielding sleeve, the electric push rod continues to pull the connecting rod to move. The limit plate squeezes the reset spring, and the guide shaft in the round opening slides from the guide groove into the spiral groove. As the connecting rod drives the spiral groove to move, the spiral groove pushes the guide shaft, causing the connected drive gear to rotate along the right docking ring and the left docking ring. The rotating drive gear drives the driven gear that meshes with it to rotate, thereby automatically driving the self-cleaning component to operate.

[0016] 3. The drive gear drives the driven gear to rotate, causing the connected transmission rod and the second bevel gear to rotate synchronously. The second bevel gear drives the meshing first bevel gear to rotate, and the first bevel gear drives the round shaft and the scraper ring to rotate. The rotating scraper ring scrapes the inner wall of the hemispherical groove and cleans the surface of the hemispherical groove on the end face of the magnetic block, completing a further comprehensive self-cleaning operation. The two ends of the scraper ring are provided with beveled end faces, which can effectively avoid secondary residue of impurities during the scraping operation and ensure that the entire mechanism can stably carry out the next adsorption and cleaning operation.

[0029] Please see Figures 1-9 An embodiment of the present invention provides a bearing ring inner surface grinding device for bearing processing and manufacturing, comprising a grinding machine 1, a positioning fixture 2 installed on the inner side of the grinding machine 1, a grinding fixture 3 installed on the inner side of the grinding machine 1 on one side of the positioning fixture 2, a telescopic component 4 provided on the drive motor rotating shaft of the grinding fixture 3, a self-cleaning component 5 provided on one side of the telescopic component 4, and a grinding wheel 6 fixedly provided on the outer side of the self-cleaning component 5.

A circular groove 46 is provided at the center of the transmission shaft 41. Movable openings 47 are provided on both the upper and lower sides of the transmission shaft 41. A limit piece 48 is fixedly installed at one end of the connecting rod 45. A return spring 49 is sleeved on the outer side of the connecting rod 45 near the limit piece 48. A docking cavity plate 410 is fixedly installed on the side of the transmission shaft 41 near the return spring 49.

[0030] The connector 44 is movably provided with a roller. The connector 44 is adapted to the circular groove 46 and the movable opening 47. The connecting rod 45 is movably provided inside the circular groove 46. The connecting rod 45 passes through the inside of the docking cavity plate 410. One end of the docking cavity plate 410 is fixedly provided with a ring cover.

[0031] The positioning fixture 2 drives the bearing ring to rotate, cooperating with the grinding fixture 3 for processing. The grinding fixture 3 controls the contact surface between the grinding wheel 6 and the bearing ring (the grinding wheel 6 does not need to rotate during the grinding process). After the grinding wheel 6 completes the grinding operation on the inner wall of the bearing ring, the grinding wheel 6 retracts from the inside of the bearing ring. At this time, the electric actuator 43 controls the connecting piece 44 to drive the connecting rod 45 to slide inside the circular groove 46. The connecting rod 45 pushes out the magnetic block 54 and extends it into the inside of the bearing ring. Relying on the magnetic force of the magnetic block 54, iron filings and impurities generated inside the bearing ring are attracted to its surface. The electric actuator 43 then pulls out the magnetic block 54, thus solving the problems of wet iron filings being difficult to clean and the cooling liquid easily washing the grinding debris into the dead corners of the inner hole, causing accumulation. The magnetic block 54 driven by the connecting rod 45 is not affected by water mist or waste liquid, and can directly adsorb fine metal grinding debris in both dry and wet states, accurately cleaning the residual impurities on the inner wall, reducing subsequent manual cleaning processes, and avoiding collision damage during workpiece transportation. After the magnetic block 54 completes adsorption, it retracts into the magnetic isolation sleeve 52. At the same time, the scraper ring 57 scrapes off the impurities attached to the surface of the magnetic block 54, realizing the self-cleaning of the magnetic block.

[0032] An installation groove 411 is provided on the inner side of the docking cavity plate 410. A right docking ring 412 is fixedly installed on the inner wall of the installation groove 411.

A circular opening 415 is provided at the center of the drive gear 413. A guide shaft 416 is fixedly installed on the upper side of the inner wall of the circular opening 415. A guide groove 417 is provided on the upper side of the connecting rod 45. A spiral groove 418 is provided on the outer side of the connecting rod 45 near the limiting piece 48.

[0033] The right docking ring 412 is correspondingly set in the annular groove 414, the round opening 415 is adapted to the connecting rod 45, the guide shaft 416 is adapted to the guide groove 417 and the spiral groove 418, the guide shaft 416 is inserted in the guide groove 417, and the guide groove 417 and the spiral groove 418 are connected.

[0034] After the magnetic block 54 is completely retracted into the magnetic shielding sleeve 52, the electric push rod 43 continues to pull the connecting rod 45 to move. The limiting plate 48 squeezes the reset spring 49, and the guide shaft 416 in the round opening 415 slides into the spiral groove 418 from the guide groove 417. As the connecting rod 45 drives the spiral groove 418 to move, the spiral groove 418 pushes the guide shaft 416, causing the connected drive gear 413 to rotate along the right docking ring 412 and the left docking ring 53. The rotating drive gear 413 drives the driven gear 515 that meshes with it to rotate, thereby automatically driving the self-cleaning component 5 to run.

[0035] The self-cleaning component 5 includes a connecting sleeve 51 fixedly disposed at one end of the docking cavity disk 410. A magnetic shielding sleeve 52 is fixedly disposed inside the connecting sleeve 51. A left docking ring 53 is fixedly disposed at one end of the magnetic shielding sleeve 52 corresponding to the position of the annular groove 414. A magnetic block 54 is movably disposed inside the magnetic shielding sleeve 52. A connecting groove 55 is formed inside the magnetic block 54. The connecting groove 55 and one end of the magnetic shielding sleeve 52 are configured as a hemispherical groove 56. A scraper ring 57 is movably disposed inside the connecting sleeve 51 on one side of the hemispherical groove 56. The inner wall of the scraper ring 57 is configured as a triangular scraper end 58. Both ends of the 7 are respectively set as beveled end faces 59. The upper and lower sides of the scraper ring 57 are respectively fixed with round shafts 510. The inner side of the connecting sleeve 51 is respectively provided with transmission grooves 511 corresponding to the positions of the two sets of round shafts 510. The outer side of the upper round shaft 510 is fixedly provided with a first bevel gear 512. The upper inner side of the connecting sleeve 51 is movably provided with a transmission rod 513 corresponding to the position of the first bevel gear 512. The second bevel gear 514 is fixedly provided on one side of the transmission rod 513 corresponding to the position of the first bevel gear 512. The driven gear 515 is fixedly provided on the other side of the transmission rod 513.

[0036] The grinding wheel 6 is fixedly installed on the outside of the connecting sleeve 51. The left mating ring 53 is correspondingly installed in the annular groove 414 on one side of the drive gear 413. The connecting groove 55 in the magnetic block 54 is sleeved on the outside of the connecting rod 45 and the limiting plate 48. The return spring 49 is installed between the limiting plate 48 and the inner wall of the connecting groove 55. The hemispherical groove 56 is adapted to the rotation trajectory of the scraper ring 57. The triangular scraper end 58 is adapted to the diameter of the magnetic block 54. The round shaft 510 passes through the transmission groove 511. The first bevel gear 512 and the second bevel gear 514 are meshed with each other. The second bevel gear 514 is installed in the upper transmission groove 511. The driven gear 515 is located inside the upper side of the mounting groove 411. The driven gear 515 is meshed with the drive gear 413.

[0037] The drive gear 413 drives the driven gear 515 to rotate, causing the connected transmission rod 513 and the second bevel gear 514 to rotate synchronously. The second bevel gear 514 drives the meshing first bevel gear 512 to rotate. The first bevel gear 512 drives the round shaft 510 and the scraper ring 57 to rotate. The rotating scraper ring 57 scrapes the inner wall of the hemispherical groove 56 and cleans the surface of the hemispherical groove 56 on the end face of the magnetic block 54, completing a further comprehensive self-cleaning operation. The scraper ring 57 has beveled end faces 59 at both ends, which can effectively prevent secondary residue of impurities during the scraping operation and ensure that the entire mechanism can stably carry out the next adsorption cleaning operation.

[0038] Working principle: During use, the positioning fixture 2 drives the bearing ring to rotate, cooperating with the grinding fixture 3 for processing. The grinding fixture 3 controls the contact surface between the grinding wheel 6 and the bearing ring (the grinding wheel 6 does not need to rotate during the grinding process). After the grinding wheel 6 completes the grinding operation on the inner wall of the bearing ring, the grinding wheel 6 retracts from the inside of the bearing ring. At this time, the electric actuator 43 controls the connecting piece 44 to drive the connecting rod 45 to slide inside the circular groove 46. The connecting rod 45 pushes out the magnetic block 54 and extends it into the inside of the bearing ring. The magnetic force of the magnetic block 54 attracts iron filings and impurities generated inside the bearing ring. After the surface is cleaned, the electric push rod 43 pulls out the magnetic block 54 to solve the problems of wet iron filings being difficult to clean and the cooling liquid washing easily washing the grinding debris into the dead corner of the inner hole, causing accumulation. The magnetic block 54 driven by the connecting rod 45 is not affected by water mist or waste liquid and can directly adsorb fine metal grinding debris in both dry and wet states, accurately cleaning the residual impurities on the inner wall, reducing subsequent manual cleaning processes, and avoiding collision damage during workpiece transportation. After the magnetic block 54 completes adsorption, it retracts into the magnetic isolation sleeve 52. At the same time, the scraper ring 57 scrapes off the impurities attached to the surface of the magnetic block 54, realizing the self-cleaning of the magnetic block. After the magnetic block 54 is completely retracted into the magnetic shielding sleeve 52, the electric push rod 43 continues to pull the connecting rod 45 to move. The limiting plate 48 squeezes the reset spring 49, and the guide shaft 416 in the round opening 415 slides into the spiral groove 418 from the guide groove 417. As the connecting rod 45 drives the spiral groove 418 to move, the spiral groove 418 pushes the guide shaft 416, causing the connected drive gear 413 to rotate along the right docking ring 412 and the left docking ring 53. The rotating drive gear 413 drives the driven gear 515 that meshes with it to rotate, thereby automatically driving the self-cleaning component 5 to run. Additionally, the drive gear 413 drives the driven gear 515 to rotate, causing the connected transmission rod 513 and the second bevel gear 514 to rotate synchronously. The second bevel gear 514 drives the meshing first bevel gear 512 to rotate, and the first bevel gear 512 drives the round shaft 510 and the scraper ring 57 to rotate. The rotating scraper ring 57 scrapes the inner wall of the hemispherical groove 56 and performs surface cleaning on the hemispherical groove 56 on the end face of the magnetic block 54, completing a further comprehensive self-cleaning operation. The scraper ring 57 has beveled end faces 59 at both ends, which can effectively prevent secondary residue of impurities during the scraping operation and ensure that the entire mechanism can stably carry out the next adsorption cleaning operation.
