[0002] In the finishing of bearing ring raceways, the grinding wheels used are often prone to high grinding forces and temperatures due to wear, clogging, and adhesion, which can have a significant impact on grinding quality. In order to maintain good grinding performance and extend the life of the grinding wheel, it must be repaired regularly. Traditional sharpening methods such as diamond tool dressing and ordinary grinding dressing methods have problems such as low sharpening accuracy, low sharpening efficiency, high sharpening difficulty, and rapid wear of sharpening tools. When used for online sharpening, they often cause significant changes in the size of the grinding wheel, which is not conducive to achieving good consistency in the product.

[0004] In the above application, the mutual cooperation between the grinding wheel electric spindle and the grinding wheel shaft assembly makes it difficult to solve the problem of cleaning the bearing ring when it is being ground on the grinding wheel shaft, resulting in the accumulation of waste after grinding, which affects the normal operation of the grinding device. Therefore, we proposed a bearing ring raceway grinder. Utility Model Content

The counterclockwise rotation of the rotating shaft drives the knocking plate to knock the inclined surface inside the waste trough to generate vibration, so that the waste stuck to the inclined surface inside the waste trough slides to the discharge port and falls into the collection box. When a certain amount of waste is accumulated inside the collection box, the staff can pull the handle to draw out the collection box through the movable slot. When the force plate is not under force, the rotating shaft is reset by the torsion spring so that it can be used for knocking next time.

When a certain amount of waste is accumulated inside the collection box, the staff can pull the handle to draw out the collection box through the movable slot. When the force-bearing plate is not under force, the rotating shaft is reset by the torsion spring so that it can be used for knocking next time.

A waste trough 54 is provided on the top of the workbench 1, and a gear 55 is rotatably connected to the top of the workbench 1. A second rack 56 is provided on the top of the workbench 1, and the side of the second rack 56 is fixedly connected to a fixed rod 57, and the bottom of the fixed rod 57 is fixedly connected to a cleaning brush 58. A discharge port 59 is provided at the bottom of the waste trough 54. The cleaning device 5 is provided on the top of the workbench 1 to clean the residual material during or after the grinding process to prevent the residual material from accumulating and affecting the normal operation of the raceway grinding device 4.

[0041] A movable groove 510 is provided on the side of the workbench 1, and a collection box 511 is slidably connected inside the movable groove 510. A handle 512 is fixedly connected to the side of the collection box 511, and a limiting plate 513 is fixedly connected to the top of the workbench 1. The collection box 511 is slidably connected inside the movable groove 510 to collect the cleaned materials, and the handle 512 is fixedly connected to the side of the collection box 511 to facilitate the staff to disassemble the collection box 511. The limiting plate 513 is fixedly connected to the top of the workbench 1 to limit the displacement distance of the second rack 56.

[0042] A push plate 514 is fixedly connected to the side of the fixed rod 57, a rotating shaft 515 is rotatably connected to the inner wall of the waste trough 54, a force plate 516 is fixedly connected to the circumferential surface of the rotating shaft 515, and a knocking plate 517 is fixedly connected to the circumferential surface of the rotating shaft 515. The functions of the push plate 514, the force plate 516 and the knocking plate 517 are to prevent residual materials from sticking to the discharge port 59 during the cleaning process, and to clean the residual materials more effectively by generating vibration.

[0043] The inner wall of the waste trough 54 is fixedly connected with a torsion spring 518, and the end of the torsion spring 518 away from the inner wall of the waste trough 54 is fixedly connected to one end of the rotating shaft 515, and the side of the connecting rod 52 is fixedly connected to a limiting telescopic rod 519. The function of the fixed connection between the end of the torsion spring 518 away from the inner wall of the waste trough 54 and one end of the rotating shaft 515 is that when the force plate 516 is not pushed by the push plate 514, the rotating shaft 515 is reset by the torsion spring 518, and the function of the fixed connection between the limiting telescopic rod 519 and the side of the connecting rod 52 is to limit the rotation connection of the threaded sleeve 51.

The side surface of the force plate 516 is located on the displacement trajectory of the push plate 514. The effect of the mutual meshing of the side surface of the first rack 53 and the circumferential surface of the gear 55 is that when the first rack 53 moves, the gear 55 is driven to rotate. The effect of the mutual meshing of the circumferential surface of the gear 55 and the side surface of the second rack 56 is that when the gear 55 rotates, the second rack 56 is driven to move. The side surface of the force plate 516 is located on the displacement trajectory of the push plate 514 to ensure that the push plate 514 can push the force plate 516 during the movement.

[0045] In this embodiment, when the raceway grinding device 4 is grinding the grinding bearing ring or after the grinding is completed, there will be residual material. At this time, the cleaning device 5 needs to be started to clean the material accumulated on the workbench 1. At this time, the drive motor 41 is started, and the output shaft of the drive motor 41 rotates counterclockwise. The output shaft of the drive motor 41 rotates counterclockwise, driving the threaded rod 42 fixed to the output shaft of the drive motor 41 to rotate counterclockwise. The counterclockwise rotation of the threaded rod 42 will drive the threaded sleeve 51 to move from left to right, and the threaded sleeve 51 moving from left to right will drive the connecting rod 52 fixed on the side of the threaded sleeve 51 to move from left to right, and the first rack 53 follows the connecting rod 52 to move from left to right. Because the first rack 53 and the gear 55 are meshed with each other, and the gear 55 and the second rack 56 are meshed with each other, the first rack 53 moves from left to right and drives the gear 55 to rotate counterclockwise, and the gear 55 rotates counterclockwise and drives the second rack 56 to move from right to left. The second rack 56 moves from right to left, while driving the cleaning brush 58 at the bottom of the fixed rod 57 to move from right to left, cleaning the residual material inside the waste trough 54. When the residual material is cleaned to the discharge port 59, the push plate 514 follows the fixed rod 57 to move from right to left to the top of the discharge port 59. At the same time, the push plate 514 pushes the force-bearing plate 516. The force-bearing plate 516 is pushed to rotate counterclockwise through the rotating shaft 515, and the rotating shaft 515 rotates counterclockwise. The clockwise rotation drives the knocking plate 517 to knock on the inner inclined surface of the waste trough 54 to generate vibration, so that the waste stuck on the inner inclined surface of the waste trough 54 slides to the discharge port 59 and falls into the collection box 511. When a certain amount of waste is accumulated inside the collection box 511, the staff can pull the handle 512 to pull out the collection box 511 through the movable slot 510. When the force plate 516 is not under force, the rotating shaft 515 is reset by the torsion spring 518 for the next knocking use.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
