[0024] Please refer to Figures 1-7 , a bearing ring grinding device, including a base plate 1 and a first motor 2 fixed on its top. The output end of the first motor 2 is fixedly connected with a rotating rod 3. One end of the rotating rod 3 is connected with a clamping mechanism 4 for fixing bearing rings of different specifications. A grinding mechanism 5 is fixedly connected to the top of the base plate 1:

[0025] Furthermore, the clamping mechanism 4 includes a housing 401. Two tooth plates 403 are slidably connected up and down inside the housing 401. A gear 404 is rotatably connected to the center inside the housing 401. The gear 404 meshes with the two tooth plates 403. An installation groove 406 is opened at one end of the tooth plate 403. One side of the inner wall of the installation groove 406 is fixedly connected with a first electric push rod 407. The movable end of the first electric push rod 407 is fixedly connected with a first telescopic member 408. One end of the first telescopic member 408 is fixedly connected with a clamping plate 410. One side of the clamping plate 410 is in contact with the inner wall of the bearing ring.

[0026] When it is necessary to grind bearing rings of different sizes, the operator can set the bearing ring to be processed outside the housing 401. Subsequently, the operator can start the second motor 405, and the second motor 405 drives the gear 404 to rotate inside the housing 401. When the gear 404 rotates, it drives the toothed plate 403 engaged with it to slide along the chute 402 towards the outside of the housing 401. When the toothed plate 403 slides outwards, the first electric push rod 407 can be started simultaneously. The first electric push rod 407 drives the first telescopic member 408 and the clamping plate 410 to gradually approach the inner wall of the bearing ring until the surface of the clamping plate 410 fits against the inner wall of the bearing ring, facilitating the fixation of bearing rings of different specifications at the clamping mechanism 4. Then, the first motor 2 can be started, and the first motor 2 drives the rotating rod 3, the clamping mechanism 4, and the bearing ring to be ground to rotate at a high speed. The provided grinding mechanism 5 facilitates the grinding of the left and right surfaces of the bearing ring. Through the above design, the clamping mechanism 4 of the device is conveniently adjusted. The clamping mechanism 4 can adapt to bearing rings with different inner diameters, eliminating the need to replace a large number of special fixtures, expanding the applicable range of the grinding device. Through the precise control of the electric control system, precise control of the clamping force can be achieved, avoiding workpiece damage caused by over-tight or over-loose clamping.

[0027] Further, one side of the housing 401 is fixedly connected to one end of the rotating rod 3, and corresponding chutes 402 are provided at the top and bottom of the inner wall of the housing 401. The chutes 402 are slidably connected to the toothed plate 403.

[0028] When the gear 404 rotates, due to the meshing relationship between the gear 404 and the toothed plate 403, the toothed plate 403 will move smoothly and precisely along the chute 402, thereby adjusting the distance between the two clamping plates 410 to adapt to bearing rings with different inner diameters. Such a design not only ensures the stability and accuracy of the clamping action but also improves the adaptability of the device to bearing rings of different specifications.

[0029] Further, a second motor 405 is fixedly connected to one side of the housing 401, and the output end of the second motor 405 extends to the inner wall of the housing 401 and is fixedly connected to the inner wall of the gear 404.

[0030] Through the operation of the second motor 405, the rotation of the gear 404 can be precisely controlled, and then the synchronous relative sliding of the two toothed plates 403 can be achieved, accurately adjusting the clamping degree of the clamping mechanism 4 on the bearing ring.

[0031] Further, a second telescopic member 409 is fixedly connected between the housing 401 and the clamping plate 410. The second telescopic member 409 includes a second positioning sleeve 4090, and a second movable rod 4091 is slidably connected inside the second positioning sleeve 4090. One end of the second movable rod 4091 extends outside the second positioning sleeve 4090 and is fixedly connected to one side of the clamping plate 410.

[0032] The provided second telescopic member 409 is used in conjunction with the second positioning sleeve 4090 and the second movable rod 4091, enabling the clamping plate 410 to adjust its position horizontally to accommodate bearing rings of different inner diameters. The second movable rod 4091 slides inside the second positioning sleeve 4090. When it is necessary to change the contact position between the clamping plate 410 and the bearing ring or compensate for the space requirements due to the thickness difference of the bearing ring, precise adjustment can be achieved by controlling the second telescopic member 409, ensuring that the clamping plate 410 always fits the inner wall of the bearing ring, providing a stable clamping effect and further enhancing the stability and precision during the grinding process.

[0033] Furthermore, one side of the second positioning sleeve 4090 is fixedly connected to the front and rear surfaces of the housing 401. A second spring 4092 is fixedly connected between the second positioning sleeve 4090 and the second movable rod 4091.

[0034] During the actual clamping process, the second spring 4092 can provide an appropriate elastic force when the second movable rod 4091 moves. On the one hand, it can achieve adaptive clamping according to the actual size of the bearing ring. On the other hand, when releasing the bearing ring, the resilience of the second spring 4092 can help the clamping plate 410 quickly return to its original position, facilitating the next round of clamping operations and also reducing the possible damage caused by hard impacts to the bearing ring or the clamping mechanism 4 itself.

[0035] Furthermore, the first telescopic member 408 includes a first positioning sleeve 4080 fixedly connected to the movable end of the first electric push rod 407. A first movable rod 4081 is slidably connected inside the first positioning sleeve 4080. One end of the first movable rod 4081 is fixedly connected to one side of the clamping plate 410. A first spring 4082 is fixedly connected between the first positioning sleeve 4080 and the first movable rod 4081.

[0036] When the first electric push rod 407 is activated, it will push the first movable rod 4081 to perform a linear motion inside the first positioning sleeve 4080, thereby driving the clamping plate 410 to approach or move away from the inner wall of the bearing ring horizontally, achieving the clamping or loosening of the bearing ring.

[0037] Furthermore, the grinding mechanism 5 includes a mounting plate 501. The left and right sides of the bottom of the mounting plate 501 are fixedly connected with second electric push rods 502. The movable ends of the second electric push rods 502 are fixedly connected with grinding blocks 503. The opposite sides of the grinding blocks 503 are in contact with the left and right side surfaces of the bearing ring. One side of the mounting plate 501 is fixedly connected with a connecting frame 504. One end of the connecting frame 504 is fixedly connected with a third electric push rod 505. The bottom of the third electric push rod 505 is fixedly connected to the top of the bottom plate 1.

[0038] When the second electric push rod 502 operates, it can precisely control the position of the grinding block 503 to make it fit against the left and right surfaces of the bearing ring, thus realizing the grinding operation on the outer ring. This bilateral grinding design can ensure the balance and high efficiency of grinding. The third electric push rod 505 can control the entire grinding mechanism 5 to move up and down in the vertical direction to adapt to the grinding of bearing rings with different thicknesses or adjust the grinding depth during the grinding process to ensure that the ground bearing rings have ideal dimensional accuracy and surface quality.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
