[0021] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0022] like Figures 1-4 The invention relates to a surface grinding device for bearing rings, comprising a worktable 1, a grinding chamber 2 and a first support 3 on the worktable 1, a grinding mechanism inside the grinding chamber 2, and a turntable 4 rotatably mounted on the first support 3. A plurality of U-shaped grooves 5 for placing bearing rings 10 are evenly arranged on the outer circumference of the turntable 4. The front half of the turntable 4 extends into the grinding chamber 2, and the grinding mechanism grinds the end face of the bearing rings 10 within the U-shaped grooves 5. A limiting component for confining the bearing rings 10 within the U-shaped grooves 5 is also provided on the front half of the turntable 4.

[0023] By setting a grinding chamber 2 and a first support base 3 on the worktable 1, and rotating a turntable 4 with U-shaped grooves 5 on the first support base 3, batch continuous processing of bearing rings 10 is realized, which greatly improves production efficiency. The U-shaped grooves 5 evenly distributed on the outer circumference of the turntable 4 can hold multiple bearing rings 10 at the same time, which significantly shortens the clamping time compared with the traditional single clamping method. The front half of the turntable 4 extends into the grinding chamber 2, and the end face of the bearing ring 10 in the U-shaped groove 5 can be ground by the grinding mechanism, which ensures the continuity of processing. At the same time, the limiting component set in the front half of the turntable 4 can limit the bearing ring 10 to be located in the U-shaped groove 5, effectively preventing the bearing ring 10 from shifting and falling off during the grinding process, thereby improving the grinding accuracy and surface quality of the bearing rings and ensuring the consistency and reliability of the products.

[0024] In this utility model, the grinding mechanism includes a rotating shaft 21, and grinding wheels 22 are symmetrically spaced on the rotating shaft 21 and located inside the grinding box 2. One end of the rotating shaft 21 extends outside the grinding box 2 and is connected to a first power mechanism 23.

[0025] By installing a rotating shaft 21 inside the grinding chamber 2, grinding wheels 22 are symmetrically installed on the rotating shaft 21 at intervals, so that the position of the grinding wheels 22 corresponds to the end face of the bearing ring 10 in the U-shaped groove 5 on the turntable 4; one end of the rotating shaft 21 is extended to the outside of the grinding chamber 2 and connected to the first power mechanism 23. The first power mechanism 23 includes a motor and a belt drive assembly, which is a conventional design and will not be described in detail here. The motor is started to drive the rotating shaft 21 to rotate, thereby causing the grinding wheels 22 to grind the end face of the bearing ring 10 that enters the grinding chamber 2.

[0026] A second power mechanism 93 for driving the turntable 4 to rotate is provided on the workbench 1. The second power mechanism 93 has the same structure as the first power mechanism 23.

[0027] Furthermore, a grinding fluid nozzle 31 for spraying grinding fluid is also provided inside the grinding chamber 2. The grinding fluid nozzle 31 is installed at a suitable position inside the grinding chamber 2 so that the spray direction of the nozzle can cover the grinding area of ​​the bearing ring 10 and the grinding wheel 22, which plays a role in cooling, lubrication and chip removal, reducing grinding temperature, reducing grinding wheel wear, improving grinding surface quality and extending grinding wheel service life.

[0028] Furthermore, a waste liquid collection tank 41 is provided on the lower side of the workbench 1, and the lower end of the grinding box 2 is connected to the waste liquid collection tank 41 through a pipe; when the grinding fluid sprayed by the grinding fluid nozzle 31 carries the debris and flows down from the grinding area, it flows into the waste liquid collection tank 41 through the pipe, keeping the working environment clean and facilitating the centralized treatment of waste liquid and debris, which meets environmental protection requirements.

[0029] See Figure 3 , Figure 4 As shown, the limiting component includes a semi-circular stop bar 51 and side-circular stop bars 52 disposed on both sides of the semi-circular stop bar 51. The semi-circular stop bar 51 is fixedly disposed on the grinding box 2, and the side-circular stop bar 52 is provided with a clearance notch 53 for avoiding the grinding wheel 22.

[0030] A semi-circular stop bar 51 is fixedly installed on the grinding chamber 2, so that its position corresponds to the position of the bearing ring 10 in the U-shaped groove 5 on the turntable 4, and fits against the outer circumference of the bearing ring 10, which can limit the bearing ring 10 in the arc direction. Side arc-shaped stop bars 52 are installed on both sides of the semi-circular stop bar 51, and clearance notches 53 are opened on the side arc-shaped stop bars 52. The position of the clearance notches 53 corresponds to the grinding wheel 22. When the turntable 4 drives the bearing ring 10 into the grinding chamber 2, the radial and axial directions of the bearing ring 10 are limited by the semi-circular stop bar 51 and the two side arc-shaped stop bars 52, and at the same time the grinding wheel 22 grinds the bearing ring 10 through the clearance notches 53.

[0031] See Figures 1-3 As shown, a vertical material trough 61 is provided above the turntable 4. The vertical material trough 61 is fixedly installed on the grinding box 2, and the upper end is connected to an inclined feed channel 62. The vertical material trough 61 is fixedly installed on the grinding box 2 above the turntable 4, and the inclined feed channel 62 is connected to the upper end of the vertical material trough 61. The bearing ring 10 to be processed is placed on the feed channel 62. Under the action of gravity, the bearing ring 10 slides down the feed channel 62 into the vertical material trough 61, and then falls from the vertical material trough 61 into the U-shaped groove 5 of the turntable, reducing manual operation and improving the degree of automation and production efficiency.

[0032] Of course, a vibrating feeder can also be connected to the other end of the feed channel 62 for automatic feeding.

[0033] Furthermore, a second support base 73 is provided on the workbench 1 and directly below the turntable 4. An inclined downward discharge channel 71 is hinged to the second support base 73, and a receiving box 72 is provided at the lower end of the discharge channel 71. When the bearing ring 10 that has been ground on the turntable 4 rotates to the position of the discharge channel 71, the bearing ring 10 slides out from the U-shaped groove 5 by its own weight and slides into the receiving box 72 along the discharge channel 71, which further improves the degree of automation and reduces manual intervention.

[0034] See Figure 1 , Figure 3 As shown, a spring 81 is connected between the lower side of the discharge channel 71 and the worktable 1. An upwardly extending vertical rod 82 is provided on the hinge shaft of the discharge channel 71. Protrusions 83 are evenly distributed along the circumference of the end face of the turntable 4. The protrusions 83 can follow the rotation of the turntable 4 and push against the extending vertical rod 82. When the turntable 4 rotates, the protrusions 83 rotate with the turntable 4 and push against the extending vertical rod 82, causing the discharge channel 71 to rotate slightly around the hinge shaft. Then, after the protrusions 83 leave the extending vertical rod 82, the discharge channel 71 vibrates under the action of the spring 81, ensuring that the bearing ring 10 effectively falls into the receiving box 72 for collection and avoids blockage.

[0035] See Figure 2 As shown, a third support base 91 is provided on the worktable 1, and a sweeping brush 92 is provided on the third support base 91. The sweeping brush 92 abuts against the U-shaped groove 5 of the turntable 4. When the turntable rotates, the sweeping brush 92 can clean the U-shaped groove 5, remove residual debris and impurities, ensure the cleanliness of the U-shaped groove 5, and avoid affecting the subsequent placement and positioning accuracy of the bearing rings.
