[0001] The utility model belongs to the technical field of bearing ring polishing, in particular to a bearing ring polishing device for bearing production and processing. Background Art

[0002] Bearings are a crucial component in modern machinery. Their primary function is to support rotating parts, reduce friction during movement, and ensure rotational accuracy. To minimize wear on bearing components, maintain bearing precision and stability, and extend their service life, bearing rings must possess excellent wear resistance and are typically polished to reduce friction.

[0003] As disclosed in patent application number CN202323193932.6, a bearing ring polishing device includes a fixed frame, a power motor, and a support column.

[0029] A second support column 15 is connected to one side of each first support plate 16 between the workbench 10 and the top plate 11, a slide groove 33 is provided on one side of each first support plate 16, a slide column 34 is slidably provided in each slide groove 33, and each slide column 34 is fixedly connected to one side of the second support column 15, and a water sprayer 29 is provided on the end surface of the workbench 10 on one side of the polishing roller 20.

[0030] Specifically, the second motor 35 and the third motor 36 are both ordinary motors, which are existing technologies and will not be elaborated in detail in this solution. The second motor 35 and the third motor 36 respectively drive the first transmission roller 13 and the second transmission roller 14 to rotate, so that the bearing rings placed on the first transmission roller 13 and the second transmission roller 14 can move horizontally along the axial direction of the first transmission roller 13 and the second transmission roller 14.

[0031] The push cylinder 31 is a hydraulic push cylinder, an electric push cylinder, etc., which is the existing technology and will not be elaborated in detail in this solution. The push cylinder 31 drives the clamping frame 19 to move vertically up and down. The up and down movement of the clamping frame 19 drives the first support plate 16 and the funnel 18 to rotate along the rotating connection part between the first support plate 16 and the second support plate 21, so that the device can be adapted to polishing operations for bearing rings of different sizes.

[0032] The fourth motor 37 is also an ordinary motor, which is a prior art and will not be elaborated in detail in this solution. The output end of the fourth motor 37 drives the polishing roller 20 to rotate and polish the bearing ring.

[0033] The conveyor belt 17 is a waterproof conveyor belt, which is a prior art and will not be elaborated in detail in this solution. Its conveying end surface is roughened to carry metal debris in the polishing liquid mixture that falls onto the conveying end surface of the conveyor belt 17 and convey it to the collection frame 23.

[0034] Further, such as Figure 1 and Figure 6 As shown, two second support plates 21 are provided on the side walls of the clamping frame 19 on both sides of the scraper 22 , and each second support plate 21 is rotatably connected to the top of the first support plate 16 .

[0035] Further, such as Figure 1 and Figure 4 As shown, a water tank 28 is provided below each workbench 10 on one side of the funnel 18 , a first pipe 27 is provided between the funnel 18 and the water tank 28 , and a second pipe 30 is provided between the sprinkler 29 and the second pipe 30 .

[0036] Specifically, polishing liquid is stored in the water tank 28 , and a water pump is provided inside the water tank 28 . The output end of the water pump can deliver the polishing liquid to the water sprayer 29 through the second pipe 30 .

[0037] Further, such as Figure 4 As shown, a connecting plate 25 is provided between every two adjacent first support plates 16 .

[0038] Specifically, the provision of the connecting plate 25 can strengthen the connection between the two first support plates 16 , so that the two first support plates 16 can rotate synchronously.

[0039] Further, such as Figure 2 As shown, a collecting frame 23 is rotatably provided between the second supporting column 15 and the polishing roller 20 below the first supporting plate 16 .

[0040] Specifically, the collecting frame 23 can collect the metal debris separated from the waste polishing liquid scraped by the scraper 22 to prevent the debris from falling to other positions of the bearing ring polishing device, which is inconvenient to clean.

[0041] Further, such as Figure 2 and Figure 6 As shown, a vibrator 32 is provided on one side of each first support plate 16 above the collecting frame 23 .

[0042] Specifically, the vibrator 32 is an ordinary vibrator, which is an existing technology and will not be elaborated in detail in this solution. The setting of the vibrator 32 enables the metal debris in the waste polishing liquid flowing on the conveying end face of the conveyor belt 17 to fall onto the conveying end face of the conveyor belt 17 more quickly, and the subsequent metal debris can fall from the transmission end face of the conveyor belt 17 to the inside of the collection frame 23 more quickly.

[0043] Further, such as Figure 7 As shown, a plurality of guide plates 24 are provided on the conveying end surface of the conveyor belt 17 , and the inclined angle formed by the guide plates 24 and the first support plate 16 is less than 90 degrees.

[0044] Specifically, the guide plate 24 is made of an elastic, bendable and deformable material. Since the conveying direction of the conveyor belt 17 is upward, the waste polishing liquid on the conveyor belt 17 flows in the opposite direction of the conveying direction of the conveyor belt 17 under the action of gravity. At this time, the waste polishing liquid easily flows to the gap between the first support plate 16 and the conveyor belt 17, resulting in the polishing liquid being unable to be recycled again. The setting of the guide plate 24 can guide the waste polishing liquid on the conveying end face of the conveyor belt 17, so that the polishing liquid with separated impurities can flow smoothly to the inside of the funnel 18 for secondary recovery.

[0045] First, start the second motor 35 and the third motor 36, and place the bearing ring to be polished on the transmission end surface between the first transmission roller 13 and the second transmission roller 14. While the sliding column 34 and the second transmission roller 14 rotate, the bearing ring will move horizontally between the first transmission roller 13 and the second transmission roller 14 along the axial direction of the first transmission roller 13 and the second transmission roller 14. When it moves to the vicinity of the second support column 15, start the fourth motor 37, the first motor 26, the water sprinkler 29 and the vibrator 32. The water sprinkler 29 sprays the polishing liquid onto the outer circumferential surface of the bearing ring. The output end of the fourth motor 37 drives the polishing roller 20 to rotate to polish the outer circumferential surface of the bearing ring. During polishing, the polishing roller 20 will absorb a large amount of polishing liquid and metal debris generated by polishing. While the polishing roller 20 rotates, the scraper 22 will scrape off the polishing liquid on the polishing roller 20.

[0046] Next, the scraped waste polishing liquid flows from the end face of the scraper 22 to the conveying end face of the conveyor belt 17. At this time, the first motor 26 drives the conveyor belt 17 to rotate. The polishing liquid is opposite to the conveying direction of the conveyor belt 17 under the action of gravity. Since the end face of the conveyor belt 17 is rough, the metal debris in the waste polishing liquid will be transported upward by the conveyor belt 17 under the action of gravity and the friction force of the conveying end face of the conveyor belt 17, and the separated polishing liquid flows downward along the conveying end face under the action of the guide plate 24. In this process, the vibration of the vibrator 32 effectively helps the metal debris in the waste polishing liquid to quickly precipitate and separate.

[0047] Finally, the polishing liquid that has separated the metal debris will flow along the transmission end surface of the conveyor belt 17 into the funnel 18, and then flow into the water tank 28 through the first pipe 27. Driven by the water pump, the polishing liquid will flow again into the sprinkler 29 through the second pipe 30 and then be sprayed out.

[0048] When polishing bearing rings of different diameters, the push cylinder 31 can be started, and the output end of the push cylinder 31 drives the clamping frame 19 to move up and down for adjustment, thereby adjusting the polished outer cylindrical surface of the polishing roller 20 to contact the outer cylindrical surface of the bearing ring that needs to be polished. When the clamping frame 19 moves downward, it will drive the second support plate 21 to move downward. The downward movement of the second support plate 21 will cause the first support plate 16 to rotate along the connection between the first support plate 16 and the second support plate 21. With the cooperation of the slide groove 33 and the slide column 34, the end of the conveyor belt 17 close to the scraper 22 follows the polishing roller 20 to move up and down, so that the conveyor belt 17 can convey and separate the waste polishing liquid scraped off the scraper 22.
