[0002] The rolling surface of the roller is spherical. A bearing using such a roller has self-aligning performance and can withstand a large load. Spherical rollers are divided into asymmetric and symmetric types. Generally, the large end face of the asymmetric type is spherical, and the two end faces of the symmetric type are flat end faces. The symmetric spherical rollers have better performance, while the asymmetric type is a phased-out form. Such rollers are used in spherical roller bearings and thrust spherical roller bearings.

[0003] During the processing of bearing rollers, it is necessary to modify the arc at the end of the rollers. In the prior art, when modifying the arc at the end of bearing rollers, a bearing roller end arc profile modification device is used for modification. When the current arc profile modification device clamps the bearing roller, it is necessary for workers to hold the bearing roller all the time to facilitate the clamping of the bearing roller by the arc profile modification device. Although the purpose of clamping and fixing the bearing roller is achieved in this way, the labor intensity of workers is relatively large during the clamping process of the bearing roller. Therefore, it is necessary to design an end arc profile modification device for bearing rollers. Summary of the Utility Model

[0027] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments to facilitate understanding of the content of the present utility model. The methods used in the present utility model are all conventional methods unless otherwise specified; the raw materials and devices used are all conventional commercially available products unless otherwise specified.

[0028] Referring to Figures 1-6 , a device for end arc modification of a bearing roller provided by the present utility model includes a workbench 1. A lifting mechanism 2 and a rotating mechanism 4 are arranged at the upper end of the workbench 1, and a transmission mechanism 3 is arranged at the lower end of the workbench 1. The workbench 1 is connected to the rotating mechanism 4 through the transmission mechanism 3. A clamping mechanism 5 is arranged inside the rotating mechanism 4, and the clamping mechanism 5 is used for clamping and fixing the bearing roller.

[0029] Specifically, the bearing roller to be modified is placed on the lifting mechanism 2, and then the lifting mechanism 2 works, and the bearing roller can be moved to the middle of the clamping mechanism 5, so that it is convenient for the clamping mechanism 5 to clamp the bearing roller, so that the bearing roller does not need to be manually held by hand all the time during the clamping process, thereby reducing the labor intensity of the workers. After clamping the bearing roller, the lifting mechanism 2 works downward. At this time, with the cooperation of the transmission mechanism 3, the rotating mechanism 4 can be driven to move upward, so that the rotating mechanism 4 is far away from the workbench 1, which is convenient for the rotating mechanism 4 to work. When the rotating mechanism 4 works, the bearing roller can be driven to rotate. As the bearing roller rotates, after the grinding plate contacts the bearing roller, the bearing roller can be modified.

[0030] Further, the lifting mechanism 2 includes a first rack 201, a lifting seat 202, a first motor 203, a threaded block 204, a lead screw 205, a first guide rod 206, a guide seat 207, and a connecting plate 208. The first rack 201 is slidably connected inside the workbench 1. The upper end of the first rack 201 is fixedly connected to the lifting seat 202. Both sides of the lower end of the first rack 201 are fixedly connected to the guide seats 207. The first guide rod 206 is slidably connected inside the guide seats 207. The first guide rod 206 is fixedly connected to the workbench 1. The lower end of the first guide rod 206 is fixedly connected to the connecting plate 208. The lead screw 205 is rotatably connected inside the connecting plate 208. The threaded block 204 is threadedly connected to the circumferential surface of the lead screw 205. The threaded block 204 is fixedly connected to the first rack 201. The lower end of the workbench 1 is fixedly connected to the first motor 203. The output end of the first motor 203 is fixedly connected to the lead screw 205. During operation, when the first motor 203 works, the first rack 201 can be driven to move under the cooperation of the lead screw 205 and the threaded block 204. As the first rack 201 moves, the lifting seat 202 can be driven to move. When the lifting seat 202 moves upward, the bearing rollers on the lifting seat 202 can enter the clamping mechanism 5, thus facilitating the clamping mechanism 5 to clamp the bearing rollers. When the lifting seat 202 moves downward, it does not prevent the rotating mechanism 4 from rotating.

[0031] The transmission mechanism 3 includes a bearing seat 301, a gear 302, a second rack 303, and a rotating shaft 304. The bearing seat 301 is fixedly connected to the lower end of the workbench 1. The rotating shaft 304 is rotatably connected inside the bearing seat 301. The gear 302 is fixedly connected to the circumferential surface of the rotating shaft 304. The front end of the gear 302 meshes with the first rack 201. The rear end of the gear 302 meshes with the second rack 303. The second rack 303 is slidably connected to the workbench 1. During operation, when the first rack 201 moves upward, the second rack 303 can be driven to move downward under the cooperation of the gear 302, thereby driving the clamping mechanism 5 to move downward, so as to facilitate the clamping of the bearing rollers. When the first rack 201 moves downward, the second rack 303 can be driven to move upward under the cooperation of the gear 302, so that the rotating mechanism 4 is away from the workbench 1, thus facilitating the operation of the rotating mechanism 4.

[0032] The rotating mechanism 4 includes a mounting base 401, a U-shaped frame 402 and a second motor 403. The upper end of the second rack 303 is fixedly connected to the mounting base 401. The rear end of the mounting base 401 is fixedly connected to the second motor 403. The output end of the second motor 403 penetrates through the mounting base 401 and is rotatably connected to the mounting base 401. The output end of the second motor 403 is fixedly connected to the U-shaped frame 402. During operation, when the second motor 403 works, it can drive the U-shaped frame 402 to rotate. As the U-shaped frame 402 rotates, it can drive the bearing rollers to rotate, thus facilitating the arc modification of the bearing rollers. When the second motor 403 stops working, the U-shaped frame 402 always remains in a horizontal state, which is convenient for later clamping of the bearing rollers.

[0033] The clamping mechanism 5 includes a bidirectional threaded rod 501, a moving plate 502, a clamping plate 503, a slide rail 504 and a handle 505. The bidirectional threaded rod 501 is rotatably connected inside the U-shaped frame 402. The end of the bidirectional threaded rod 501 is fixedly connected to the handle 505. The circumferential surface of the bidirectional threaded rod 501 is threadedly connected to the moving plate 502. There are two moving plates 502, which are symmetrically distributed on the bidirectional threaded rod 501. The internal thread directions of the two moving plates 502 are opposite. The opposite surfaces of the two moving plates 502 are both fixedly connected to the clamping plate 503. The slide rail 504 is fixedly connected inside the U-shaped frame 402, and the slide rail 504 is slidably connected to the moving plate 502. During operation, rotate the handle 505. At this time, with the cooperation of the bidirectional threaded rod 501, it can drive the moving plate 502 to slide on the slide rail 504, and then drive the clamping plate 503 to move. When the clamping plates 503 move towards each other, the clamping of the bearing rollers can be realized, which is convenient for the rotating mechanism 4 to drive the bearing rollers to rotate.

[0034] The lower end of the mounting base 401 is fixedly connected to a second guide rod 6, and the second guide rod 6 is slidably connected to the workbench 1. During operation, by setting the second guide rod 6, under the action of the second guide rod 6, the movement of the mounting base 401 can be made more stable, which is convenient for the rotating mechanism 4 to work stably.

[0036] However, the above are only specific embodiments of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby.
