[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. In terms of their role, it should be support, which is literally used to support the shaft. However, this is only part of their role. The essence of support is to be able to bear radial loads, which can also be understood as being used to fix the shaft. The bearing quick and easy automatic selection is included, which is to fix the shaft so that it can only rotate, while controlling its axial and radial movement. The motor cannot work at all without bearings.

[0003] Currently, after initial forming, bearings are polished according to different workpiece requirements. Bearing rings often require their edges and corners to be polished into thin-walled corners. In existing technology, when performing thin-walled corner polishing on the ring, the ring is first fixed on a fixture, and then a polishing device is used to control the polishing tool to approach the ring for polishing. However, during the polishing process, the polished edges of the ring will fly and eventually accumulate at the bottom of the device. After the work is completed, the staff needs to clean it up. The processing steps are cumbersome and the entire process is time-consuming and labor-intensive. To this end, we propose a thin-walled corner cutting and polishing device for bearing rings.

The moving mechanism 17 inside the grinder 1 includes two groups of first gears 18 respectively arranged at both ends of the swing rod 13 and fixedly connected thereto. The first gear 18 is meshed with a rack 19 that is slidably connected to the inside of the grinder 1. An electric telescopic rod 20 is installed at one end of the rack 19 close to the fixed shaft 6. The output end of the electric telescopic rod 20 faces the fixed shaft 6. The two groups of racks 19 are fixedly connected to one end of the electric telescopic rod 20 close to the electric telescopic rod 20 with a sliding plate 21. A through slot 22 is provided on the sliding plate 21. The side diameter of the through slot 22 is larger than the diameter of the electric telescopic rod 20.

[0019] like Figure 2-Figure 4 as well as Figure 10As shown, the blowing assembly 9 includes a hood 25 arranged on the outside of the rear side of the grinder 1 and fixedly connected thereto, a wind wheel 26 is rotatably connected to the inside of the hood 25, an air outlet end of the hood 25 is fixedly connected to an air outlet pipe 27 communicating with the inside thereof, the other end of the air outlet pipe 27 is located inside the grinder 1 and above the fixed shaft 6, one end of the air outlet pipe 27 located inside the grinder 1 is tilted downward, and is fixedly connected to an air outlet row 28 located above the collecting box 4, an air inlet end of the hood 25 is fixedly connected to an air inlet pipe 29 communicating with the inside thereof, and the wind wheel 26 is connected to a power mechanism 30 arranged on the outside of the rear side of the grinder 1; In addition, the power mechanism 30 includes an electric motor 31 arranged on the outside of the rear side of the grinder 1 and fixedly connected thereto, the output end of the motor 31 is fixedly connected to a power shaft 32, the wind wheel 26 is fixedly connected to a rotating shaft 33 rotatably connected to the wind cover 25, and a pulley group 34 is transmitted between the power shaft 32 and the rotating shaft 33. The output end of the electric telescopic rod 20 is connected to a trigger member 35 for controlling the operation of the motor 31. The trigger member 35 includes a control switch 36 arranged inside the grinder 1 and close to the rear side. The control switch 36 is electrically connected to the motor 31. The end of the electric telescopic rod 20 is fixedly connected to an extension shaft 37, and a pressing block 38 corresponding to the position of the control switch 36 is fixedly connected to the extension shaft 37.

[0020] In a specific embodiment, after the grinding of the bearing ring is completed, the waste chips generated will be accumulated in the collection box 4 under the clamp seat 2. At this time, the electric telescopic rod 20 is controlled to operate, and the output end of the electric telescopic rod 20 extends outward, and at the same time drives the translation plate 23 at the end to move, and the translation plate 23 drives the driving rod 24 at the same time, and through the fixed connection of the driving rod 24, drives the sliding plate 21 to slide inside the grinder 1. When the sliding plate 21 moves, it moves outside the electric telescopic rod 20 through the notch 22, and the sliding plate 21 simultaneously pulls the two sets of racks 19, which are meshed with the first gear 18 through the rack 19. When moving, the rack 19 drives the first gear 18 to rotate, and the two sets of first gears 18 cooperate to bring the swing shaft 12 The swing shaft 12 is rotated in the connecting column 11, and the arch frames 10 at both ends of the connecting column 11 are fixed inside the grinder 1, so that when the swing shaft 12 rotates, it always rotates with the connecting column 11 as the center of the circle, and the swing rod 13 fixedly connected to the swing shaft 12 swings accordingly, and drives the upper push shaft 14 to move. The overall lower end position of the swing rod 13 remains unchanged, and the upper end moves toward the front side of the grinder 1. When the push shaft 14 moves accordingly, it rotates with the sliding seat 15 and pushes the sliding seat 15 to move in the sliding groove 16. At this time, the height of the end of the collecting box 4 near the front side decreases, and the rotating seat 5 at the other end rotates on the fixed shaft 6, eventually making the collecting box 4 tilted, and the waste chips in the collecting box 4 slide directly from the tilted collecting box 4 to the tilted groove 8; When the electric telescopic rod 20 is in operation, the output end drives the growth shaft 37 to move, and drives the pressing block 38 at the end to move. When the collection box 4 is tilted to the maximum angle, the pressing block 38 contacts the control switch 36 and presses it. Since the motor 31 is electrically connected to the control switch 36, the motor 31 is operated at the rear side of the outside of the grinder 1. The motor 31 drives the power shaft 32 to rotate through the output end, and drives the rotating shaft 33 to rotate through the transmission connection of the pulley group 34, and drives the wind wheel 26 to rotate in the wind cover 25 through the rotating shaft 33. At this time, the wind cover 2 5 forms a wind flow, the wind hood 25 sucks air into the interior through the air inlet pipe 29, and the wind enters the air outlet pipe 27 through the air outlet end of the wind hood 25, and is finally discharged through the air outlet row 28. The wind blown out by the air outlet row 28 can blow the inside of the inclined collection box 4, and the residual waste chips are blown by the wind force, so that the waste chips in the collection box 4 can be thoroughly cleaned, and slide from the inclined collection box 4 to the inclined groove 8. The waste chips are removed from the grinder 1 through the inclined groove 8, and the switch door 7 can be directly opened to be uniformly collected outside the grinder 1, which saves the time of subsequent manual cleaning and improves work efficiency.
