DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 7As shown, a bearing ring polishing device comprises a processing table 1, a fixing mechanism 2 is arranged on the upper part of the processing table 1, a supporting table 3 is arranged at the rear side of the processing table 1, a supporting arm 4 is connected to the upper part of the supporting table 3, a polishing motor 5 is arranged on the upper part of the supporting arm 4, the polishing motor 5 is driven and connected to a driving shaft 2 46, a rotating arm 6 is connected to the lower end of the driving shaft 2 46, an adjusting hole 1 7 is opened on the rotating arm 6, a grinding mechanism 8 is installed in the adjusting hole 1 7 through a mounting bolt 1 9, the grinding mechanism 8 comprises a mounting plate 51, a mounting bolt 1 9 is connected to the upper part of the mounting plate 51, a side grinding block 57 is arranged in the middle position of the mounting plate 51, and the mounting plate 51 is provided with an adjusting hole 2 58 at the upper and lower sides of the side grinding block 57, an end face grinding block 59 is arranged at the adjusting hole 2 58, a mounting bolt 2 60 is connected to the outer side of the end face grinding block 59, and the mounting bolt 2 60 is arranged through the adjusting hole 2 58. The adjustment hole 7 cooperates with the mounting bolt 9 to adjust the position of the grinding mechanism 8 so that the grinding mechanism 8 can grind bearing rings of different diameters. The height of the two end surface grinding blocks 59 can be adjusted, and they can contact the upper end surface and the lower end surface of the bearing ring, and can grind bearing rings of different thicknesses. The side grinding block 57 and the end surface grinding block 59 can act on the bearing ring at the same time, and jointly grind the upper end surface, the lower end surface, and the outer peripheral surface of the bearing ring to complete the polishing process of the bearing ring.

[0023] Furthermore, a movable hole 52 is provided in the middle of the mounting plate 51, and a lifting rod 54 is connected to the outside of the side grinding block 57. The lifting rod 54 passes through the movable hole 52, and a positioning column 56 is vertically provided in the movable hole 52. The positioning column 56 passes through the lifting rod 54, and a spring 53 is sleeved on the positioning column 56. The lower end of the spring 53 is connected to the bottom of the movable hole 52, and the upper end of the spring 53 is connected to the lower part of the lifting rod 54. A transmission shaft 3 48 is rotatably provided in the positioning column 56, and one end of the transmission shaft 3 48 passes through the positioning column 56 and is connected to a cam 50, which is arranged against the lifting rod 54. An active bevel gear 3 47 is installed on the driving shaft 2 46, and a driven bevel gear 4 49 is connected to one end of the transmission shaft 3 48 close to the driving shaft 2 46, and the driven bevel gear 4 49 is meshed with the active bevel gear 3 47. The polishing motor 5 drives the rotating arm 6 to rotate through the driving shaft 2 46, and the rotating arm 6 drives the grinding mechanism 8 to rotate to grind the bearing ring. At the same time, the active bevel gear three 47 on the driving shaft two 46 drives the transmission shaft three 48 to rotate through the meshing driven bevel gear four 49, and the transmission shaft three 48 then drives the cam 50 to rotate. Due to the structural characteristics of the cam 50, when it rotates, it will act on the lifting rod 54 to move it up and down, thereby changing the height of the side grinding block 57, and the contact height between the side grinding block 57 and the outer periphery of the bearing ring changes. With this structural design, the side grinding block 57 does not contact the entire periphery of the bearing, and the friction between the two is small, which can avoid the two from getting stuck to each other, and at the same time, the powder generated during grinding can be discharged normally. The small contact surface between the two can reduce the heat generated during grinding and avoid deformation of the outer periphery of the bearing ring due to excessive temperature.

[0024] Since the rotating arm 6 rotates multiple times during grinding and the height of the side grinding block 57 changes differently, the outer peripheral surface of the bearing ring can still be completely ground without omission.

[0025] A limiting seat 55 is provided on the upper part of the lifting rod 54, and a part of the cam 50 is located in the limiting seat 55. By setting the limiting seat 55, the cam 50 is limited so that the cam 50 and the lifting rod 54 will not be misaligned.

[0026] Furthermore, a mounting groove 11 is provided on the upper part of the processing table 1, a driving motor 13 is provided in the mounting groove 11, the driving motor 13 is connected to a driving shaft 16, an active bevel gear 17 is installed on the driving shaft 16, a plurality of screw grooves 10 are provided on the processing table 1 at the periphery of the mounting groove 11, the plurality of screw grooves 10 are evenly distributed and the number is not less than three, a screw 14 is rotatably provided in the screw groove 10, and the screw 14 is provided along the length direction of the screw groove 10, The end of the screw rod 14 close to the driving shaft 16 is connected to the driven bevel gear 15, and the driven bevel gear 15 can mesh with the active bevel gear 17. A screw slider 26 is installed on the screw rod 14. The fixing mechanism 2 includes a moving block 19, and the moving block 19 is installed on the screw slider 26. An installation cavity 61 is opened in the moving block 19, and a tightening block 20 and a tightening block 21 are installed in the installation cavity 61. The tightening block 20 and the tightening block 21 are arranged to pass through the installation cavity 61.

[0027] When the active bevel gear 17 on the driving shaft 16 is meshed with the driven bevel gear 15, the driving motor 13 drives the driving shaft 16 to rotate, and the active bevel gear 17 drives the screw 14 on the driven bevel gear 15 to rotate, thereby driving the screw slider 26 to move, and the screw slider 26 drives the moving block 19 to move outward, so that the outer ends of the tightening block 1 20 and the tightening block 21 can extend into the inner groove of the bearing ring, and the outer ends of the tightening block 1 20 and the tightening block 21 abut against the inner groove of the bearing ring, thereby completing the fixation of the bearing ring.

[0028] The fixing mechanism 2 fixes the inner groove position of the bearing ring. This fixing method prevents the fixing mechanism 2 from contacting the upper end face, lower end face and outer peripheral face of the bearing ring, so that the grinding mechanism can grind these three faces simultaneously, thereby improving the grinding efficiency. There is no need to change the clamping position during processing, which can reduce the processing time.

[0029] Furthermore, a sliding groove 27 is provided on the relatively close side of the clamping block 21 and the clamping block 1 20, a sliding block 31 is slidably arranged in the sliding groove 27 of the clamping block 21, and a sliding block 32 is slidably arranged in the sliding groove 27 of the clamping block 20, and a fixed seat 33 is installed on the side of the sliding block 131 and the sliding block 232 away from the moving block 19, and an air bag 30 is arranged on the sliding block 131 and the sliding block 232, and a part of the air bag 30 is fixedly installed in the fixed seat 33, an air pump 34 is installed in the sliding block 131, and a ventilation pipe 35 is connected to the air pump 34, and the end of the ventilation pipe 35 away from the air pump 34 is installed in the air bag 30, and a cylinder 28 is arranged in the clamping block 21, and the piston rod of the cylinder 28 is connected to the sliding block 131. The air cylinder 28 can control the extension of its movable rod to drive the sliding block 1 31 to move, and the sliding block 1 31 also drives the sliding block 2 32 to move, so that the airbag 30 is close to the inner groove of the bearing ring. The air pump 34 pumps gas into the airbag 30 to expand the airbag 30. The expanded airbag 30 can press against the inner groove of the bearing ring to make up for the insufficient fixing effect of the pressing block 1 20 and the pressing block 2 21, and strengthen the fixing effect.

[0030] Furthermore, the part of the pressing block 1 20 located in the installation cavity 61 is connected to the rack 1 22, the part of the pressing block 21 located in the installation cavity 61 is connected to the rack 23, a rotating shaft 36 is rotatably arranged in the middle position of the installation cavity 61, a transmission gear 25 is installed on the rotating shaft 36, the rack 1 22 and the rack 2 23 are respectively located on both sides of the transmission gear 25, the rack 1 22 and the rack 2 23 are meshed with the transmission gear 25, the upper end of the rotating shaft 36 passes through the moving block 19 and is connected to the driven bevel gear 3 37, and also includes a transmission mechanism, the driving shaft 1 16 is connected to the active bevel gear 2 18, the active bevel gear 2 18 drives the driven bevel gear 3 37 to rotate through the transmission mechanism, and a part of the sliding block 2 32 is inserted into the sliding block 1 31. A trigger 29 is also arranged at the ends of the pressing block 2 21 and the pressing block 1 20. The transmission mechanism includes a support plate 43, on which a transmission shaft 42 is rotatably arranged, and one end of the transmission shaft 42 close to the driving shaft 16 is connected to a driven bevel gear 2 44, and a mounting seat 39 is connected to the moving block 19, and a transmission shaft 2 40 is rotatably arranged in the mounting seat 39, and one end of the transmission shaft 2 40 is connected to a transmission bevel gear 38, and the transmission bevel gear 38 is meshed with the driven bevel gear 3 37, and a slot 45 is provided at one end of the transmission shaft 42 away from the driven bevel gear 2 44, and one end of the transmission shaft 2 40 away from the transmission bevel gear 38 is inserted into the slot 45, and a lifting mechanism 12 is arranged in the mounting groove 11, and the lifting mechanism 12 is driven and connected to the driving motor 13.

[0031] When the abutting block 1 20 and the abutting block 2 21 move outward to abut against the inner groove of the bearing ring, the trigger 29 will be triggered. The driving motor 13 is driven to move upward by the lifting mechanism 12, so that the active bevel gear 2 18 is meshed with the driven bevel gear 2 44. When the driving motor 13 drives the driving shaft 1 16 to rotate, the meshed driven bevel gear 2 44 is driven to rotate through the active bevel gear 2 18, and the driven bevel gear 2 44 then drives the transmission bevel gear 38 to rotate through the transmission shaft 1 42 and the transmission shaft 2 40. The transmission bevel gear 38 drives the meshed driven bevel gear 3 37 to rotate, and then drives the transmission gear 25 on the rotating shaft 36 to rotate. The transmission gear 25 acts on the rack 1 22 and the rack 2 23 to move them, and the rack 1 22 and the rack 2 23 then drive the abutting block 1 20 and the abutting block 2 21 to move respectively, so that the distance between the two is increased, and the contact area between the airbag 30 and the inner groove of the bearing ring can be increased, and the fixing effect can be enhanced. At the same time, the bearing rings with different diameters can be fixed to expand the scope of use.

[0032] A limiting rod 24 is disposed in the mounting cavity 61 , and a portion of the limiting rod 24 is inserted into the rack 1 22 and the rack 2 23 . The limiting rod 24 can limit the rack 1 22 and the rack 2 23 when they move.
