[0002] In the automotive manufacturing and wheel repair industry, the quality of wheel hubs is directly related to the driving safety and stability of vehicles. The grinding process of the inner wall of the wheel hub is one of the key links to ensure the quality of the wheel hub. It not only affects the appearance of the wheel hub, but also plays an important role in its dynamic balance performance.

[0003] For example, CN221755623U discloses a grinding device for processing the inner wall of an automobile wheel hub, comprising a processing box, with bottom pads evenly aligned on the bottom surface of the processing box, a side passage groove on one side of the processing box, a sealing inner plate snapped into the inner side of the side passage groove, a control panel fixedly embedded on one side of the processing box, bottom screw holes evenly aligned on the bottom surface of the processing box, a connecting screw fixedly inserted into the top surface of the bottom pads, a collection box horizontally arranged on the inner bottom surface of the processing box, horizontal plates symmetrically arranged on the inner side of the processing box, and adjusting cylinders horizontally and symmetrically bolted to the inner side of the processing box. A mounting side groove is horizontally snapped into the side of the horizontal plate away from the adjusting cylinder. The sealed operating structure makes the processing cleaner, more hygienic, and safer, while the adjustable structure allows for grinding of various sizes.

[0004] Traditional wheel hub inner wall grinding relies heavily on manual operation, which can easily lead to unstable grinding force and grinding area, affecting the stability of wheel hub quality. In addition, manual grinding is inefficient, and long-term operation can easily cause worker fatigue, further increasing quality risks. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-7 As shown, a wheel hub inner wall grinding device includes a worktable 1 and a screw drive mechanism 2. The worktable 1 has a dust extraction hole 101 on its surface, and a vacuum cleaner 102 is installed on the lower end of the worktable 1. The screw drive mechanism 2 includes a first motor 201, and a first screw 202 is fixedly installed at the output end of the first motor 201. The first screw 202 is rotatably connected to the worktable 1. A first guide rod 203 is fixedly installed on the worktable 1. A slider 204 is movably sleeved on the first screw 202 and the first guide rod 203. The slider 204 is slidably engaged in a groove on the worktable 1, and is screwed into the first screw 202. A grinding mechanism 3 is installed on the lower end of the slider 204. Grinding mechanisms 3 are installed on both sides of the surface of the worktable 1. There is an arc plate grinding mechanism 4, and a hub rotating mechanism 5 is installed on the surface of the worktable 1. When in use, the first motor 201 is first powered on. When the first motor 201 is powered on, it can drive the first lead screw 202 to rotate. Then, the slider 204 is driven through the engagement between the first lead screw 202 and the slider 204. At the same time, the first guide rod 203 passes through both sides of the slider 204, so as to prevent the slider 204 from rotating when it moves. This drives the grinding mechanism 3 installed on the lower end face of the slider 204 to adjust its position to meet the grinding needs of different positions of the hub. The dust generated during the grinding process is collected through the dust suction hole 101 and the vacuum cleaner 102.

[0025] The grinding mechanism 3 includes a second motor 301. A first telescopic cylinder 302 is fixedly mounted on one end face of the second motor 301. A second lead screw 303 is fixedly mounted on the output end of the second motor 301. The second lead screw 303 is rotatably connected to the first telescopic cylinder 302. A second guide rod 304 is fixedly mounted inside the first telescopic cylinder 302. A telescopic sleeve 305 is movably sleeved on the first telescopic cylinder 302. A first limiting sleeve 306 is fixedly mounted inside the telescopic sleeve 305. The first limiting sleeve 306 is movably sleeved on the second lead screw 303 and the second guide rod 304, and the first limiting sleeve 306 is screwed into the second lead screw 303. A fourth motor 307 is fixedly installed on one end face of the telescopic sleeve 305. A grinding block 308 is fixedly installed on the output end of the fourth motor 307. In use, the second motor 301 is first energized. When the second motor 301 is working, it can drive the second lead screw 303 to rotate. Then, the first limit sleeve 306 is driven by the engagement of the second lead screw 303 with the first limit sleeve 306, thereby causing the telescopic sleeve 305 to move telescopically. When the telescopic sleeve 305 moves to the appropriate position, the fourth motor 307 is energized, so that the fourth motor 307 drives the grinding block 308 to rotate for grinding.

[0026] The arc-shaped grinding mechanism 4 includes a third motor 401. A second telescopic cylinder 402 is fixedly installed on one end face of the third motor 401, and a third lead screw 403 is fixedly installed on the output end of the third motor 401. The third lead screw 403 is rotatably connected to the second telescopic cylinder 402. A third guide rod 404 is fixedly installed inside the second telescopic cylinder 402. A second limiting sleeve 405 is movably sleeved on the third lead screw 403 and the third guide rod 404, and the second limiting sleeve 405 is screwed into the third lead screw 403. An arc-shaped grinding plate 406 is fixedly installed on one end face of the second limiting sleeve 405. When it is necessary to grind the outer wall of the wheel hub... The user can first power on the third motor 401. When the third motor 401 is powered on, it can drive the third lead screw 403 to rotate. Then, through the engagement between the third lead screw 403 and the second limiting sleeve 405, the second limiting sleeve 405 can be driven, allowing the second limiting sleeve 405 to extend out from the second telescopic cylinder 402. This allows the arc-shaped grinding plate 406 to be pressed against the outer wall of the hub. At the same time, the third guide rod 404 passes through one side of the second limiting sleeve 405, thus preventing the second limiting sleeve 405 and the arc-shaped grinding plate 406 from rotating when the second limiting sleeve 405 moves.

[0027] The hub rotation mechanism 5 includes a fifth motor 501. The output shaft of the fifth motor 501 passes through the worktable 1 and is fixedly mounted on a rotating seat 502. The surface of the rotating seat 502 is provided with a limiting pin 503, and a mounting plate 504 is provided on the limiting pin 503. When it is necessary to fix the hub, the hub is placed on the rotating seat 502, and the limiting pin 503 is inserted into the through hole in the hub for limiting and fixing. Then, the mounting plate 504 is fastened to the limiting pin 503, which can further strengthen the fixing of the hub. This makes it easier for the hub to be polished. The fifth motor 501 drives the rotating seat 502 to rotate, which in turn makes the hub rotate. During the rotation of the hub, the hub can contact the arc-shaped grinding plate 406 and the grinding block 308, which facilitates the grinding mechanism 3 and the arc plate grinding mechanism 4 to polish the hub.
