Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and in particular to a wheel hub surface grinding device. Background Technology

[0002] Wheel hub surface polishing devices are generally inefficient due to the large size and complex shape of the wheels themselves. They can only polish specific areas of the wheel hub at a time, and cannot complete complex surface polishing in one go. Moreover, uneven surface finish may occur during polishing, especially when the process is lengthy. Wear and tear on the polishing tools can lead to inconsistent polishing results in different areas, affecting the uniformity of the wheel hub surface quality. Furthermore, the polishing tools used (such as grinding wheels and sanding belts) generate significant friction during polishing, resulting in micro-scratches, dents, or other damage, affecting the appearance and performance of the wheel hub. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a wheel hub surface grinding device that loads and transfers the wheel hub, automatically aligns and clamps it stably, and then performs fine grinding.

[0004] The technical problem to be solved by this utility model is achieved through the following technical solution: a wheel hub surface grinding device, including a grinding platform, a loading area on one side of the grinding platform, a grinding area on the other side of the grinding platform, a mounting frame above the grinding area, a rectangular guide rail groove on the grinding platform along the loading area towards the grinding area, a slide plate in the rectangular guide rail groove, a mounting column on the slide plate, and a telescopic motor on one side of the loading area for driving the slide plate to reciprocate along the rectangular guide rail groove;

[0005] The mounting frame has a top plate and a support plate at the top. The top plate has a rotating device, and the bottom of the rotating device has a lifting device. A mounting bearing is installed between the lifting device and the support plate. Below the lifting device is a wheel hub grinding disc, which includes a disc body connected to the lifting device. The bottom of the disc body has concave and convex grinding surfaces that fit into the transverse outer surface of the wheel hub. The concave and convex grinding surfaces have a grinding layer along their surface. The sliding plate slides from the loading area to the grinding area, efficiently transferring the wheel hub. The cooperation of the rotating device and the lifting device allows the wheel hub grinding disc to move vertically and circumferentially, so that the concave and convex grinding surfaces are in close contact with the surface of the wheel hub for grinding. The grinding is uniform and smooth, and the grinding effect is good.

[0006] The mounting bracket below the wheel hub grinding disc has symmetrical clamping devices on both sides. The clamping devices hold the wheel hub in place on both sides, ensuring that the wheel hub remains fixed during the grinding process, preventing displacement and improving grinding accuracy and stability.

[0007] As a further embodiment of this invention, the concave-convex grinding surface is fitted to the shape of the outer lateral surface of the wheel hub, and the grinding surface extends circumferentially along the wheel hub. The grinding layer is provided with nylon bristles, steel wire bristles, polypropylene bristles, or fiber bristles, depending on the wheel hub material. The grinding surface adheres closely to the wheel hub surface, ensuring thorough and even grinding, resulting in a smoother wheel hub surface and avoiding obvious grinding defects. The selection of bristles with strong wear resistance and anti-aging properties, along with the variety of bristle materials adapted to different wheel hub materials, improves service life.

[0008] As a further embodiment of this invention, the rotating device includes a rotary motor mounted on a top plate. The top plate has mounting holes, and the rotary motor shaft passes vertically downwards through these holes. The end of the rotary motor shaft is fixedly connected to the top surface of the lifting cylinder body. The rotary motor shaft drives the lifting cylinder to rotate synchronously, resulting in high rotational efficiency and controllable rotational speed.

[0009] As a further embodiment of this invention, the lifting device includes a lifting cylinder. The top surface of the lifting cylinder is fixedly connected to the shaft end of a rotary motor. A mounting bearing is provided circumferentially around the lifting cylinder. A positioning hole is provided on the support plate, and the outer ring of the mounting bearing is fixedly fitted with the positioning hole. The telescopic shaft end of the lifting cylinder is vertically installed on the top surface of the wheel hub grinding disc. The lifting cylinder provides stable support, the support plate provides stable support force, and the mounting bearing generates sliding rotation, resulting in low rotational resistance and good rotational synchronization.

[0010] As a further embodiment of this invention, the clamping device includes symmetrically arranged clamping arc plates. The curvature of the two clamping arc plates corresponds to the curvature of the outer ring of the wheel hub. A clamping motor is provided on the outer side of the clamping arc plates. The shaft end of the clamping motor extends and retracts horizontally, driving the clamping arc plates closer to or away from the wheel hub. A distance sensor is provided on the side of the clamping motor closest to the clamping arc plates. The distance sensor is installed on the side of the clamping motor to monitor the distance between the clamping arc plates and the wheel hub in real time, provide feedback information, and cooperate with the clamping motor to automatically adjust the appropriate clamping force.

[0011] As a further embodiment of this utility model, parallel guide rails are provided on both sides of the rectangular guide rail groove, and a sliding groove is provided along the length of the guide rail. Horizontal sliding strips are provided on both sides of the slide plate, and the horizontal sliding strips slide in cooperation with the sliding groove. The telescopic motor body is installed on the end face of the loading area on one side of the rectangular guide rail groove. The sliding groove on the guide rail allows the slide plate to slide in cooperation with the sliding groove, ensuring stable operation of the slide plate, reducing friction, and enabling smooth movement.

[0012] As a further embodiment of this invention, the mounting post is a cylinder with a diameter smaller than that of the inner ring of the hub. The cylinder has a keyway along its vertical direction, and a key is provided between the inner ring of the hub and the keyway for an interference fit. The height of the mounting post is less than the depth of the inner ring of the hub. The hub is completely fixed circumferentially by the key, preventing any displacement or relative rotational shift, thus ensuring that the hub remains in close contact with the uneven grinding surface during grinding.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a wheel hub surface grinding device, including a grinding platform with a loading area and a grinding area. A mounting bracket is provided above the grinding area. The grinding platform has a rectangular guide groove along the direction from the loading area to the grinding area. After the wheel hub is loaded onto the sliding plate, it slides smoothly from the loading area to the grinding area along the rectangular guide groove. After the wheel hub is loaded into the grinding area, the distance between the clamping arc plate and the wheel hub is monitored in real time by a distance sensor of the clamping motor. The sensor provides feedback information and, in conjunction with the clamping motor, automatically adjusts the appropriate clamping force to clamp and fix the wheel hub, preventing displacement of the wheel hub during the grinding process and improving grinding accuracy and stability.

[0015] The rotating and lifting devices on the mounting bracket work together to allow the wheel hub grinding disc to move vertically and circumferentially, ensuring close contact between the concave and convex grinding surfaces and the wheel hub surface for even and smooth grinding with excellent results. The shape of the concave and convex grinding surfaces is precisely fitted to the shape of the wheel hub's transverse outer surface, ensuring thorough and even grinding and a smoother wheel hub surface.

Horizontal sliding strips 221 are provided on both sides of the sliding plate, and the horizontal sliding strips slide in cooperation with the sliding grooves. A telescopic motor 201 is provided on one side of the loading area to drive the sliding plate to reciprocate along the rectangular guide rail groove. The telescopic motor body is mounted on the end face of the rectangular guide rail groove on the loading area side. The telescopic motor drives the sliding plate 202 to slide along the loading area towards the grinding area. After grinding is completed, the sliding plate slides in the opposite direction along the grinding area back to the loading area for transfer.

[0022] The skateboard is equipped with a mounting post 203, which is a cylinder with a diameter smaller than that of the inner ring of the hub. The cylinder has a keyway along its vertical direction, and a key 204 is provided between the inner ring of the hub and the keyway for an interference fit. The height of the mounting post is less than the depth of the inner ring of the hub, and the mounting post does not interfere with the grinding movement. The hub is completely fixed to the mounting post in the circumferential direction by the key, and the hub does not shift or rotate relative to the surface. During the grinding process, the hub remains in close contact with the uneven grinding surface.

[0023] The mounting bracket has a top plate 302 and a support plate 301 on its top. The top plate has a rotating device, which includes a rotary motor 6. The rotary motor is mounted on the top plate, which has mounting holes. The rotary motor shaft passes vertically downward through the mounting holes, and its end is fixedly connected to the top surface of the lifting cylinder. When grinding begins, the rotary motor shaft drives the lifting cylinder to rotate synchronously.

[0024] The lower part of the rotating device is equipped with a lifting device, and a mounting bearing 4 is provided between the lifting device and the support plate. The lifting cylinder is circumferentially equipped with a mounting bearing, and the support plate is provided with a positioning hole. The outer ring of the mounting bearing is fixedly fitted with the positioning hole. The telescopic shaft end of the lifting cylinder is installed perpendicularly to the top surface of the wheel hub grinding disc. The lifting device includes a lifting cylinder, and the top surface of the lifting cylinder is fixedly connected to the shaft end of the rotary motor.

[0025] Support plate 301 supports the lifting cylinder body, which rotates synchronously with the rotating device via a bearing 4. A wheel hub grinding disc is located below the lifting device, which rotates circumferentially. The lifting device includes a lifting cylinder. When the lifting cylinder is activated, it extends axially downward, driving the wheel hub grinding disc to move vertically downward and continuously approach the wheel hub directly below.

[0026] The wheel hub polishing disc 7 includes a disc body 701 connected to a lifting device.

Each clamping device includes symmetrically arranged clamping arc plates 803, the curvature of which corresponds to the curvature of the outer rim of the wheel hub. A clamping motor 801 is located on the outer side of the clamping arc plates. The motor shaft extends and retracts horizontally, driving the clamping arc plates closer to or away from the wheel hub. A distance sensor 802 is located on the side of the clamping motor closest to the clamping arc plates. The distance sensor monitors the distance between the clamping arc plates and the wheel hub in real time, provides feedback, and, in conjunction with the clamping motor, automatically adjusts the appropriate clamping force.

[0028] When the skateboard drives the wheel hub to slide into the grinding area and is directly below the lifting cylinder, the clamping motor 801 starts, the clamping motor shaft extends and moves, driving the clamping arc plate to move towards the wheel hub. With the cooperation of the distance sensor 802, the clamping arc plate automatically adjusts the clamping force to clamp the wheel hub, and the wheel hub does not deform under stable clamping conditions.

[0029] The clamping device holds both sides of the wheel hub, keeping the wheel hub in a fixed state throughout the grinding process.
