However, in the traditional bearing ring polishing process, when polishing the outer periphery of the bearing ring, a clamp is needed to clamp the inner ring of the bearing. After the outer periphery is polished, the outer periphery of the bearing is clamped with a clamp, and then the inner ring of the bearing is polished. This results in the need to clamp the bearing ring twice when polishing, which makes the bearing ring polishing steps cumbersome and affects the polishing efficiency of the bearing ring. Summary of the invention

[0029] Reference Figure 2 , Figure 7 The upper circular guard plate 30 is provided with five receiving slots 303 corresponding to the card slots 501 one by one. The receiving slots 303 penetrate the circular guard plate 30 along the thickness direction of the circular guard plate 30.

[0030] Reference Figure 3 , Figure 5 A groove grinder 65 protruding away from the axis of the chuck 50 is fixedly provided at the middle part of the peripheral grinder 63 in the vertical direction, and the groove grinder 65 abuts against the groove on the outer periphery of the bearing ring.

[0031] Reference Figure 1 , Figure 2, Figure 3 A guide groove 111 is provided on the platform 11 and runs through the thickness thereof. The guide groove 111 is located on one side of the grinding assembly. Two symmetrically arranged sliders 22 are slidably connected in the guide groove 111. A vertically arranged pulley shaft 25 is rotatably connected in the slider 22. The two pulleys 20 are respectively fixed to the upper ends of the two pulley shafts 25. Spring seats 24 are fixed to the two side walls of the guide groove 111 perpendicular to the length direction. A tension spring 23 is fixed between the slider 22 and the adjacent spring seat 24. A motor is fixed to the lower end surface of one of the sliders 22, and the pulley shaft 25 is fixed to the rotating shaft of the motor.

[0032] When the present invention is in use, according to the thickness of the bearing ring to be polished, the first nuts 62 on the upper and lower sides are rotated, so that under the elastic force of the compression spring 64, the spacing between the upper and lower end surface grinders 60 is adjusted to be consistent with the thickness of the bearing ring, and according to the difference between the inner diameter and the outer diameter of the bearing ring, the second nut 43 is loosened so that the fixed plate 41 can slide on the support plate 42. At this time, the horizontal distance between the inner ring grinder 44 and the outer peripheral grinder 63 is adjusted to be consistent with the difference between the inner diameter and the outer diameter of the bearing ring, and then the second nut 43 is tightened to fix the fixed plate 41 on the support plate 42.

[0033] The stepper motor drives the power shaft 51 to rotate 72° and then stops for a while, and then drives the power shaft 51 to rotate 72° again, and repeats this process, so that the chuck 50 and the circular guard plate 30 rotate 72° and then stop for a while, and then rotate 72° again.

[0034] With the belt 21 facing the 5 equally divided points on the outer circumference of the chuck 50 as the zero point, the operator stands at a position 44° away from the zero point 1 and the inner ring grinder. While the chuck 50 stops rotating, the bearing ring is placed in the horizontal groove 501, the outer periphery of the bearing ring abuts against the outer periphery grinder 63, and the groove grinder 65 abuts against the groove on the outer periphery of the bearing ring. At this time, the pneumatic cylinder 40 located on its upper side is in a shortened state.

[0035] After a period of time, the stepper motor starts, driving the chuck 50 to rotate 72°, thereby driving the bearing ring to rotate 72°, and then stops. At this time, the pneumatic cylinder 40 located on the upper side of the bearing ring is started, and the inner ring grinder 44 located in the receiving groove 303 moves downward to the groove 501 along with the piston rod of the pneumatic cylinder 40, so that the inner ring grinder 44 cooperates with the outer peripheral grinder 63 to clamp the bearing ring.

[0036] After a period of time, the stepper motor restarts, and the chuck 50 drives the bearing ring to rotate until it abuts against the belt 21. During this process, the motor is always in starting rotation, thereby driving the pulley shaft 25 to rotate, and then the pulley 20 rotates, and then drives the belt 21 to rotate, thereby driving the bearing ring abutting against the belt 21 to rotate, so that the bearing ring is fully polished in the slot 501 at one time.

[0037] By repeating the above steps in a reciprocating manner, the bearing ring can be continuously polished. After the polished bearing ring rotates the inner ring grinder 44° again with the chuck 50, the pneumatic cylinder 40 is shortened and the inner ring grinder 44 is retracted into the through groove 303, so that the polished bearing ring in the groove 501 can be taken out.

[0038] In this embodiment, the size of the groove grinder 65 can be customized in multiple sizes according to different types of bearing rings. Different groove grinders 65 can be replaced for grinding operations according to different types of bearing rings.

[0039] It will be clear to those skilled in the art that various modifications to the above embodiments may be made without departing from the overall spirit and concept of the present invention.
