Description

Technical Field

[0001] This utility model relates to the field of bearing processing, specifically a bearing ring cleaning device for automotive bearing processing. Background Technology

[0002] During the manufacturing process of automotive bearings, the bearing races can become contaminated with various oils, metal shavings, and other impurities. The purpose of a cleaning device is to effectively remove these impurities, ensuring the cleanliness of the bearing race surface and improving the quality and performance of the bearing.

[0003] The announcement number is CN216941552U. To ensure the cleanliness of bearing races and meet high-precision assembly requirements, various cleaning devices are widely used. Among them, cleaning with a brush is a common method. The soft bristles of the brush can penetrate deep into the fine parts of the bearing race, effectively removing surface dirt and impurities. However, in the actual cleaning process, due to the complex processing environment of the bearing races, a large amount of iron filings often remain. These iron filings may come from cutting, grinding, and other processing steps, and vary in size and have high hardness. When cleaning the bearing races with a brush, the iron filings are carried into the inside of the brush by the bristles. As the brush rotates, the iron filings stuck inside the brush will continuously come into contact with the surface of the bearing race. Since the hardness of the iron filings is usually higher than that of the bearing race material, under continuous friction, it will cause serious wear to the bearing race. This wear will not only damage the surface finish of the bearing race and affect its appearance quality, but more importantly, it will reduce the dimensional accuracy and geometric accuracy of the bearing race, thereby affecting the assembly accuracy and service life of the bearing. Utility Model Content

[0004] The purpose of this invention is to provide a bearing ring cleaning device for automotive bearing processing. By using this device, the problem of iron filings being drawn into the inside of the brush when cleaning bearing rings with a brush is solved. As the brush rotates, the iron filings stuck inside the brush will continuously come into contact with the surface of the bearing ring. Since the hardness of the iron filings is usually higher than that of the bearing ring material, the continuous friction will cause serious wear to the bearing ring.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bearing ring cleaning device for automotive bearing processing, comprising a bearing tank, a rotating mechanism above the bearing tank, and a pushing mechanism inside the bearing tank;

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.

[0021] Please see Figure 1-5 The present invention provides a technical solution: a bearing ring cleaning device for automobile bearing processing, comprising a bearing tank 1, a rotating mechanism 2 above the bearing tank 1, and a pushing mechanism 3 inside the bearing tank 1;

[0022] The rotating mechanism 2 includes a support plate 201 fixedly connected to the top of the support barrel 1. A cylinder 210 is fixedly connected to the top of the support plate 201. A pneumatic rod 202 is fixedly connected to the output end of the cylinder 210. A fixing plate 203 is provided on the inner side of the support plate 201. A first hole 204 is provided inside the fixing plate 203. A push rod 205 is provided on the inner side of the first hole 204. A groove 206 is provided inside the lower end of the pneumatic rod 202. A rotating disk 207 is provided on the inner side of the groove 206. The rotating disk 207 has a cylindrical shape, and the upper width of the rotating disk 207 is greater than the upper width of the rotating disk 207. The outer side of the rotating disk 207 fits against the inner side of the groove 206, so that the rotating disk 207 will not wobble when rotating inside the groove 206. The inner side of the groove 206 will move out. The rotating disk 207 and the push rod 205 are fixedly connected. The middle outer side of the push rod 205 is provided with a first guide groove 208. The inner side of the first guide groove 208 is provided with a first guide rod 209. The first guide rod 209 is fixedly connected to the fixed plate 203. The central axis of the push rod 205 is perpendicular to the upper surface of the fixed plate 203. The outer side of the push rod 205 is in contact with the inner side of the first hole 204. The external structure of the push rod 205 is cylindrical, so that the push rod 205 can rotate inside the first hole 204. The external structure of the first guide groove 208 is spiral. When the first guide groove 208 moves downward, it will be pushed by the first guide rod 209 to drive the push rod 205 to rotate.

[0023] The pushing mechanism 3 includes a first brush plate 301 fixedly connected to the lower end of the push rod 205. A connecting rod 302 is fixedly connected to the lower end of the first brush plate 301. A second brush plate 303 is fixedly connected to the lower end of the connecting rod 302. A fixed cylinder 304 is provided below the second brush plate 303. A first sliding groove 305 is provided on the inner wall of the bearing barrel 1. A first slider 306 is provided on the inner side of the first sliding groove 305. The central axis of the first sliding groove 305 is parallel to the central axis of the first guide rod 209, so that the push rod 205 can drive the first slider 306 to move up and down when it moves up and down. The first slider 306 is fixedly connected to the fixed cylinder 304. A second guide groove 3 is provided on the inner wall of the fixed cylinder 304. 07. A second guide rod 308 is provided on the inner side of the second guide groove 307. A second hole 309 is provided inside the second brush plate 303. A top rod 310 is provided on the inner side of the second hole 309. The top rod 310 is fixedly connected to the second guide rod 308. A second sliding groove 311 is provided on the inner side of the second brush plate 303. A second slider 312 is provided on the inner side of the second sliding groove 311. The upper width of the second slider 312 is greater than the lower width of the second slider 312. The second slider 312 is fixedly connected to the fixed cylinder 304. The appearance structure of the second guide groove 307 is wavy, so that the second guide rod 308 will move up and down when it moves inside the second guide groove 307.

[0024] When cleaning is required, the bearing ring is placed between the first brush plate 301 and the second brush plate 303. The cylinder 210 is activated, causing the air rod 202 to move downwards, which in turn moves the groove 206 and the rotating disk 207 downwards. This causes the push rod 205 to move downwards, resulting in the first guide groove 208 moving downwards. Because the first guide groove 208 has a spiral shape, it is pushed and rotated by the first guide rod 209 on the outer side of the push rod 205. This causes the first brush plate 301 and the second brush plate 303 to rotate. Due to the weight of the bearing ring, it will not rotate. The first brush plate 301 and the second brush plate 303 rotate to clean the bearing ring. When the second brush plate 303 rotates, it drives the top rod 310 located inside the second hole 309 to rotate, which in turn causes the second guide rod 308 to rotate. Because the appearance structure of the second guide groove 307 is wavy, the second guide rod 308 drives the top rod 310 to move up and down during the rotation, causing the bearing ring to be lifted by the top rod 310. This causes the brush to change between bending and vertical, allowing the iron filings stuck inside the brush to be discharged, reducing damage to the bearing ring from iron filings during cleaning and improving the cleaning effect of the bearing ring.
