Description

Technical Field

[0001] The present invention belongs to the field of bearing polishing, and specifically relates to a polishing device for the inner raceway of a bearing. Background Art

[0002] The polishing process of shaft parts is an important link to ensure that their surface roughness meets high standards. Bearings are important components in mechanical transmission, and the inner raceway outer ring is an important part of the bearing. The accuracy and surface quality of the inner raceway outer ring have a great impact on the service life and performance of the bearing. Therefore, during the production and processing process, the inner raceway outer ring of the bearing needs to be polished.

[0003] The grinding tool for polishing the inner and outer rings of the bearing is mainly a grinding wheel. When selecting a grinding wheel, factors such as grinding wheel grain size and grinding wheel hardness need to be considered. Generally, grinding wheels with fine grain size and high hardness can improve the surface quality of the inner and outer rings of the bearing. When polishing the inner raceway of the bearing, the following issues need to be mainly noted:

[0004] During polishing, according to the different sizes of the bearings, attention needs to be paid to the center of the bearings, and the directions should be consistent to ensure the concentricity of the inner raceway. During polishing, if the center cannot be ensured to be horizontal, it will cause the grinding wheel to collide with the inner raceway of the bearing. Currently, if a fixed polishing wheel is used, it is beneficial for polishing bearings of different sizes. If an adjustable polishing wheel is used, the fixed position of the bearing needs to be adjusted according to the polishing wheel.

[0005] In summary, the present invention provides a polishing device for the inner raceway of a bearing to solve the above problems. Summary of the Invention

[0045] As an embodiment of the present invention, the driving component 5 includes a driving shaft 501, a driving shaft frame 502 and a driving motor 503. The driving shaft 501 is arranged at the same end of the moving bearing holder 7 and the positioning bearing holder 8. The driving shaft frame 502 and the driving motor 503 are installed on the surface of the polishing table 1. The driving shaft 501 is rotatably connected to the driving shaft frame 502, and the driving motor 503 is arranged at one end of the driving shaft 501 and is connected with the driving shaft 501 through a coupling.

[0046] As an embodiment of the present invention, the moving bearing holder 7 includes a moving slide frame 701. The bottom of the moving slide frame 701 is slidably arranged in a bearing holder chute 12 opened on the surface of the polishing table 1. The surface of the moving slide frame 701 is rotatably connected with a moving bearing guide roller 702 through a guide shaft. One end of the guide shaft movably penetrates through the moving slide frame 701 and is fixedly connected with a moving guide roller gear 703. A meshing moving gear 704 is vertically arranged on one side of the moving guide roller gear 703.

[0047] As an implementation manner of the present invention, a gear rack in the shape of "L" is fixedly connected to one side of the moving carriage 701 close to the moving guide roller gear 703. The meshing moving gear 704 is rotatably connected to the gear rack through a rotating shaft. The meshing moving gear 704 and the moving guide roller gear 703 are bevel gears and are meshed and connected. A matching through hole is provided in the middle of the rotating shaft. The driving shaft 501 movably penetrates through the matching through hole, and spline strips are provided on the surface of the driving shaft 501 and are arranged to match the matching through hole.

[0048] Among them, as Figure 3 , the matching through hole penetrates the gear rack, and the driving shaft 501 passes through the middle of the gear rack. When the moving bearing rack 7 moves left and right, the meshing moving gear 704 also moves back and forth on the surface of the driving shaft 501. When the driving motor 503 drives the driving shaft 501, the driving shaft 501 can drive the meshing moving gear 704 to rotate through the spline strips, and at the same time does not affect the back-and-forth movement of the meshing moving gear 704 on the driving shaft 501. When the meshing moving gear 704 rotates, it can drive the moving guide roller gear 703 to rotate, thereby realizing the rotation of the moving bearing guide roller 702 on the moving bearing rack 7.

[0049] As an implementation manner of the present invention, the positioning bearing rack 8 includes a positioning rack 801, a positioning bearing roller 802, and a meshing gear assembly. The positioning rack 801 is installed on the polishing table 1. The positioning bearing roller 802 is rotatably installed on the surface of the positioning rack 801. The meshing gear assembly includes a matching bevel gear one 803 and a matching bevel gear two 804. The middle of the matching bevel gear two 804 is vertically connected to the surface of the driving shaft 501. The positioning bearing roller 802 movably penetrates the positioning rack 801 through a power shaft and is fixedly connected to the matching bevel gear one 803. The matching bevel gear one 803 and the matching bevel gear two 804 are vertically meshed and connected.

[0050] Among them, as Figure 1 , the positioning bearing rack 8 and the moving bearing rack 7 are arranged correspondingly. The positioning bearing roller 802 and the moving bearing guide roller 702 are parallel and support on the outer wall of the bearing. Together with the bearing positioning roller 14 at the upper end, they form a clamping structure in three directions to clamp the outer circumference of the bearing.

[0051] As an implementation manner of the present invention, the two-stage adjustment mechanism 6 includes a locking tooth plate 601, a moving tooth plate 602, and a two-stage gear 603. One end of the moving tooth plate 602 is fixedly connected to the moving carriage 701. The bottom of the moving tooth plate 602 is slidably connected to the polishing table 1. The locking tooth plate 601 is installed on the polishing table 1 and is disposed opposite to the teeth on the moving tooth plate 602. The two-stage gear 603 is disposed between the locking tooth plate 601 and the moving tooth plate 602. One side surface of the two-stage gear 603 is rotatably connected to the bottom of the moving slide plate 9 through a gear shaft. The two-stage gear 603 is respectively meshed with the locking tooth plate 601 and the moving tooth plate 602.

[0052] Among them, as Figure 4 , the moving tooth plate 602 is arranged parallel to the locking tooth plate 601. When the two-stage gear 603 moves, it first pushes the moving tooth plate 602 forward. Secondly, the locking tooth plate 601 is fixed. Therefore, when the two-stage gear 603 translates, the two-stage gear 603 will rotate along the locking tooth plate 601, further pushing the moving tooth plate 602 to move forward or backward, with a double-spacing movement.

[0053] As an implementation manner of the present invention, two track bars 11 are installed on the polishing table 1. Sliding tables 10 are respectively slidably connected to the track bars 11. The moving slide plate 9 is fixedly connected to the surface of the sliding table 10. One end of the gear shaft is rotatably connected to the side wall of one of the sliding tables 10.

[0054] Among them, as Figures 4 - 5 , the sliding table 10 slides on the track bar 11. The sliding table drives the gear shaft to move back and forth, and further drives the two-stage gear 603 to move back and forth. When pushing the moving slide plate 9 to translate, the displacement adjustment of the moving bearing bracket 7 can be realized, and the lifting plate 2 always remains at the middle position between the moving bearing bracket 7 and the positioning bearing bracket 8.

[0055] As an implementation manner of the present invention, the polishing frame 3 includes a polishing positioning plate 301. A rotating shaft sleeve 303 is rotatably connected to the polishing positioning plate 301. One end of the rotating shaft sleeve 303 penetrates through the polishing positioning plate 301. A rotating shaft rod 304 is movably penetrated through the rotating shaft sleeve 303. The rotating shaft rod 304 and the rotating shaft sleeve 303 are a spline shaft and a spline sleeve, and longitudinal key bars are arranged on the surface of the rotating shaft rod 304. A servo motor 305 is installed on one side of the polishing positioning plate 301 close to the moving bearing bracket 7. One end of the servo motor 305 movably penetrates through the polishing positioning plate 301 and is fixedly connected with a driving wheel. The driving wheel is connected to the surface of the rotating shaft sleeve 303 through a belt drive. A cylinder frame 302 is installed on the side of the polishing positioning plate 301 away from the moving bearing bracket 7. A hydraulic rod 306 is installed on the cylinder frame 302. The piston rod of the hydraulic rod 306 passes through the cylinder frame 302 and is rotatably connected to one end of the rotating shaft rod 304. A polishing wheel is installed at the other end of the rotating shaft rod 304.

[0056] As an implementation manner of the present invention, a slideway groove is formed in the lifting plate 2 along its length direction, and the polishing positioning plate 301 is slidably connected in the slideway groove. The top of the polishing positioning plate 301 is connected with a locking lead screw 307. One end of the locking lead screw 307 penetrates into the top of the lifting plate 2 and penetrates out of the top of the slideway groove, and is rotatably connected to the surface of the polishing positioning plate 301. The locking lead screw 307 is threadedly connected with the polishing positioning plate 301.

[0057] Among them, as Figure 6 , when the locking lead screw 307 rotates, it drives the polishing positioning plate 301 to move up and down, thereby adjusting the height of the polishing wheel. The polishing wheel can be driven to rotate by the servo motor 305. When the servo motor 305 starts, it drives the driving wheel to rotate, and then the belt rotating shaft sleeve 303 rotates, so that the polishing wheel rotates accordingly. The hydraulic rod pushes the polishing wheel to move back and forth, moving back and forth inside the inner slideway of the bearing for multi-displacement polishing.

[0058] As an implementation manner of the present invention, a locking hydraulic rod 13 is installed on the surface of the polishing table 1, and the piston rod of the locking hydraulic rod 13 is fixedly connected to the bottom of the moving slide plate 9.

[0059] Among them, as Figure 7 , when the locking hydraulic rod 13 is started, it pushes the moving slide plate 9 to move, thereby adjusting the positions of the moving bearing bracket 7 and the lifting plate 2.

[0060] When polishing the bearing, first place the bearing between the moving bearing bracket 7 and the positioning bearing bracket 8. The outer wall of the bearing is in contact with the moving bearing guide roller 702 and the positioning bearing roller 802. The driving motor 503 drives the driving shaft 501 to rotate, thereby driving the moving bearing guide roller 702 and the positioning bearing roller 802. The top of the bearing is restricted by the liftable bearing positioning roller 14, and anti-slip sleeves are sleeved on the surfaces of the moving bearing guide roller 702, the positioning bearing roller 802 and the bearing positioning roller 14 to prevent the bearing from shifting.

[0061] When adjusting according to the size of the bearing, the locking hydraulic rod 13 can be used to push the entire lifting plate 2 to move, and then the position of the moving bearing bracket 7 can be adjusted by using the two-stage adjustment mechanism 6. Then, by rotating the locking lead screw 307, the polishing positioning plate 301 is driven to move on the lifting plate 2 for adjustment according to the center height of the bearing;

[0062] When polishing, the servo motor 305 drives the rotating shaft sleeve 303 to rotate, and the locking lead screw 307 pushes the rotating shaft rod 304 to move back and forth, so that the polishing wheel can move back and forth inside the inner slideway of the bearing and perform polishing.
