[0002] In modern industrial manufacturing, bearings are critical mechanical components, and their quality and performance directly affect the operating efficiency and lifespan of the entire equipment. Shuttle bearings, as an important component in specific application scenarios, have even stricter requirements for machining accuracy and surface quality. During the bearing production process, especially the grinding of the inner and outer diameters, is one of the key steps to ensure bearing performance. Grinding not only removes excess material from the surface and improves surface quality, but also meets specified dimensional and precision requirements.

[0003] Traditional bearing grinding tools mostly employ a fixed grinding method. While this method can achieve some surface grinding of the bearing, it has significant limitations. Specifically, fixed grinding devices can typically only grind a portion of the bearing surface, making it difficult to achieve uniform treatment of the entire bearing surface. This localized grinding not only affects the overall precision of the bearing but may also lead to uneven surface quality, thereby impacting the bearing's rotational performance and lifespan.

[0004] In addition, existing grinding equipment requires adjustments after clamping during the grinding process, which not only increases processing time but may also affect the final processing accuracy due to clamping errors. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1-5 This embodiment discloses a grinding device for processing shuttle bearings, comprising a base 1, a slide table 2 slidably connected to the base 1, a grinding disc 3 rotatably connected to the slide table 2, a centering fixture 4 on one side of the grinding disc 3, the center of the centering fixture 4 being on the same horizontal line as the axis of the grinding disc 3, a fixing frame 5 slidably connected to the centering fixture 4, the fixing frame 5 being fixedly connected to the base 1, a storage cavity 6 on the fixing frame 5, the storage cavity 6 being located directly below the centering fixture 4, and a waste box 7 slidably connected inside the storage cavity 6.

[0024] The slide table 2 is slidably mounted above the base 1, and the fixed frame 5 is fixedly connected to the end of the base 1. The slide table 2 can slide left and right relative to the fixed frame 5. A rotating grinding roller 304 is mounted on the slide table 2. When the slide table 2 approaches the fixed frame 5 at a certain distance, the grinding roller 304 contacts the bearing fixed on the centering fixture 4. The grinding roller 304 grinds the bearing to remove burrs from the bearing surface. The centering fixture 4 is located on the fixed frame 5, and the centerline of the centering fixture 4 is on the same horizontal straight line as the axis of the grinding disc 3. Thus, the slide table 2 drives the grinding roller to grind the bearing. When the grinding roller 304 slides left and right, it ensures that the grinding roller 304 is directly facing the fixed bearing, thus ensuring that the grinding roller 304 grinds the bearing thoroughly. The fixing brackets 5 on both sides of the centering fixture 4 are equipped with guard plates. The width of the guard plates is greater than the width of the centering fixture 4. The guard plates block the grinding debris. The blocked debris falls into the collection cavity 6 below the fixing bracket 5 under the action of gravity. The waste box 7 is slidably connected in the collection cavity 6. The debris that enters the collection cavity 6 eventually falls into the waste box 7, and the same waste box 7 collects and processes the debris.

[0025] Centering fixture 4 refers to a device in which several fixing components synchronously spread or converge relative to the center of the fixture and have a self-locking function. The left slider 401 and right slider 402 within the centering fixture 4 slide relative to each other. The telescopic rod 407 between the right slider 402 and the fixing frame 5 is a hydraulic telescopic rod 407. The rope length of the telescopic rod 407 is automatically controlled by a hydraulic controller. Figure 4 As shown, when the telescopic rod 407 extends, under the limit of the guide rail, the right slider 402 moves to the left. The leftward movement of the right slider 402 drives the connecting pin 406 to move to the left. The connecting pin 406, in conjunction with the connecting groove 405, drives the connecting rod 404 to rotate clockwise. When the connecting rod 404 rotates clockwise, the connecting groove 405 on the upper side of the connecting rod 404 drives the connecting pin 406 on the left slider 401 to move to the right. The connecting pin 406 on the left slider 401 drives the left slider 401 to move to the right. Under the connecting action of the connecting pin 406, the distance between the movement of the left slider 401 and the right slider 402 is the same. The synchronous relative movement of 02 drives the synchronous relative movement of the left clamping block 408 and the right clamping block 409. Through the relative sliding of the left clamping block 408 and the right clamping block 409, the center of the fixed bearing and the axis of the grinding disc 3 are ensured to be on the same axis. A roller 410 is installed between the connecting pin 406 and the connecting groove 405. The roller 410 changes the sliding friction between the connecting pin 406 and the connecting groove 405 into rolling friction, so that the connecting pin 406 can move better in the connecting groove 405. The connecting groove 405 is to avoid interference during the rotation of the connecting rod 404 and ensure that the connecting rod 404 can drive the left slider 401 and the right slider 402 to move synchronously.

[0026] Both the left clamping block 408 and the right clamping block 409 have a slot 416 at one end. The inner side of the slot 416 has an arc-shaped structure, and the outer side of the slot 416 has a cross-section. The cross-section of the slot 416 is larger than the sum of the cross-sections of the left clamping block 408 and the right clamping block 409. Through the design of the slot 416, the left clamping block 408 and the right clamping block 409 can fix both the inner and outer diameters of the bearing. In addition, the design of the slot 416 can prevent the fixed bearing from being too close to the fixing frame 5, thus ensuring the bearing's stability. The left side of the bearing has a certain protrusion relative to the left clamping block 408 and the right clamping block 409, which facilitates the grinding of the bearing surface. Furthermore, the left clamping block 408 and the right clamping block 409 have through holes that cooperate with the cylindrical rod 413. The cylindrical rod 413 passes through the through holes and passes through the left clamping block 408 and the right clamping block 409. The two ends of the cylindrical rod 413 are connected to baffles 414. The springs 415 installed on the inner side of the two baffles 414 exert an inward elastic force on the left clamping block 408 and the right clamping block 409 respectively.

[0027] The indicator block 411 has a prism structure, and the indicator groove 412 contains the bearing shaft diameter value. When the connecting rod 404 rotates, it drives the two indicator blocks 411 to rotate. The reading in the indicator groove 412 corresponding to the indicator block 411 is the bearing shaft diameter value.

[0028] After knowing the bearing's shaft diameter, the grinding roller 304 can be adjusted to deviate from the center of the gripper by a corresponding distance. During grinding, when the slide table 2 drives the turntable 301 and the grinding roller 304 to approach the fixed bearing, the grinding roller 304 will just fit against the side of the bearing, thus completing the grinding operation on the side of the bearing. The grinding roller 304 is rotatably mounted on the adjusting block 303, and the adjusting block 303 is positioned by the second adjusting screw 306. The adjusting groove 302 and the guide rod 305 guide the movement of the adjusting block 303. The slide table 2 is adjusted by the first adjusting screw 9 of the guide groove 8. The first adjusting screw 9 can be driven by hand or by a motor installed on the first adjusting screw 9.

[0029] The overall workflow of this utility model is as follows: First, the slide table 2 is positioned away from the fixed frame 5. The left clamping block 408 and the right clamping block 409 on the fixed frame 5 are aligned and fixed relative to the outer side of the bearing. At this time, according to the position of the indicator block 411, the grinding roller 304 on the turntable 301 is adjusted to a position where the outer side of the grinding roller 304 just contacts the inner diameter of the bearing. Then, the slide table 2 drives the turntable 301 to move closer to the bearing. At this time, the turntable 301 grinds the front side of the bearing, and the grinding roller 304 grinds the inner diameter of the bearing. After grinding is completed, the slide table 2 is reset, and then the bearing is flipped over. The left clamping block 408 and the right clamping block 409 are aligned and fixed relative to the inner diameter of the bearing. Then, according to the indicator block 411, the grinding roller 304 is moved to a position where it contacts the outer diameter of the bearing. Then, the slide table 2 is moved closer to the bearing. At this time, the other side of the bearing and the outer diameter of the bearing are ground, thereby completing the comprehensive grinding process of the bearing and avoiding grinding dead corners.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
