[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile and is mounted on an axle. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material.

[0003] Most of the car wheel hub bearings used to be used in pairs of single row tapered roller or ball bearings. With the development of technology, car wheel hub units have been widely used in cars. The wheel hub is also called the wheel rim.

[0004] There are three methods for manufacturing aluminum alloy wheels: gravity casting, forging, and low-pressure precision casting. Gravity casting uses gravity to pour aluminum alloy melt into the mold, and after forming, it is processed and polished on a lathe to complete the production. The manufacturing process is relatively simple, does not require precise casting technology, has low cost and high production efficiency, but is prone to bubbles (sand holes), uneven density, and insufficient surface smoothness.

[0005] At present, when grinding the burrs on the surface of the wheel hub, it is difficult to fix the wheel hub with a brush during grinding because the wheel hub is a round shaft structure, and the traditional brush is not easy to fit the wheel hub surface, which affects the grinding efficiency.

When the grinding is completed and the frame plate 3 is cleaned, the staff sweeps the debris into the cleaning groove 7 to facilitate the collection and cleaning of the debris on the frame plate 3.

[0026] The grinding assembly 4 includes a slider 44, two sliders 44 are provided, and a bottom plate 45 is fixedly installed on the top of the two sliders 44, and a positioning rod 43 is fixedly installed on both sides of the top of the bottom plate 45, and a top plate 41 is fixedly installed on the top of the positioning rod 43. The staff adjusts the position of the slider 44 in the guide rail 2 according to the hub shaft diameter, so that the polishing piece 42 is more closely fitted to the hub surface, and then the staff starts the motor 6, so that the motor 6 rotates to drive the hub to rotate so that the hub and the polishing piece 42 generate friction, and the hub is squeezed with the polishing piece 42 when rotating, so that the polishing piece 42 is squeezed and contacts the hub more closely, thereby increasing the contact area between the hub and the hub, so that the polishing force of the polishing piece 42 on the hub is strengthened.

[0027] The slider 44 is slidably fitted inside the guide rail 2 , and a polishing member 42 is fixedly mounted at the middle of the bottom of the top plate 41 and the middle of the top of the bottom plate 45 , and the polishing member 42 is frictionally fitted with the surface of the wheel hub.

[0028] The polishing member 42 includes a mounting block 425, two mounting blocks 425 are provided, elastic bands 421 are fixedly mounted on the surfaces of the two mounting blocks 425, an arc-shaped covering frame 422 is fixedly mounted between the opposite surfaces of the elastic bands 421, an extrusion-fitting block 424 is fixedly mounted on the surface of the arc-shaped covering frame 422, and a grinding block 423 is fixedly mounted on the surface of the extrusion-fitting block 424. Since the wheel hub is a round shaft structure, it needs to fit with its surface when it is polished. Before polishing, the staff moves the position of the slider 44 so that the arc-shaped covering frame 422 is displaced to the side close to the wheel hub, and the extrusion-fitting block 424 and the grinding block 423 are squeezed with the surface of the wheel hub, so that the fit is tighter during polishing, thereby improving the polishing efficiency.

[0029] The mounting blocks 425 are respectively arranged at the middle of the bottom of the top plate 41 and the middle of the top of the bottom plate 45 , the extrusion and fitting block 424 is arranged as a flexible structure, and the grinding block 423 is frictionally matched with the surface of the wheel hub.

[0030] The second embodiment is based on the first embodiment. Figure 6 to Figure 7As shown, the positioning protection member 5 includes a through shaft 54, a shaft 51 is rotatably mounted at the axis of the through shaft 54, a mounting plate 55 is fixedly mounted on the outer surface of the shaft 51, four mounting plates 55 are provided, and the four mounting plates 55 are circumferentially distributed on the surface of the shaft 51, and inner support members 53 are rotatably mounted inside the mounting plates 55, and bottom stabilizing members 52 are fixedly mounted between the intersections of the mounting plates 55. The staff sets the wheel hub on the surface of the shaft 51, at which time the bottom of the wheel hub is placed above the mounting plate 55, and the bottom stabilizing member 52 is squeezed, and then the staff rotates the inner support member 53 upward, so that the inner support member 53 is supported in the wheel hub cavity to support and position the wheel hub, and then the staff starts the motor 6 so that the output end of the motor 6 drives the through shaft 54 ​​and the shaft 51 to rotate, so that the wheel hub rotates and generates friction with the grinding assembly 4.

[0031] The through shaft 54 ​​is sleeved on the output end of the motor 6, and the through shaft 54 ​​penetrates the frame plate 3 and extends to the top thereof. The inner support member 53 is clamped in the wheel hub cavity, and the bottom stabilizing support member 52 is arranged at the bottom of the wheel hub.

[0032] The inner support member 53 includes an adjustment block 534, a cushion block 535 is fixedly installed inside the adjustment block 534, a clamp block 532 is rotatably installed inside the adjustment block 534 through the cushion block 535, a fixing rod 531 is passed through the inside of the clamp block 532, and a clamping rod 533 is fixedly installed on the top of the clamp block 532 through the fixing rod 531. The staff rotates the clamp block 532 so that the clamp block 532 rotates upward inside the cushion block 535, and at this time, the clamp block 532 drives the clamping rod 533 to rotate in the wheel hub cavity until it contacts the inner wall thereof, and the clamp block 532 and the clamping rod 533 abut against both sides of the inner wall of the wheel hub cavity, thereby supporting and limiting the wheel hub, and preventing the wheel hub from deflecting during rotation and polishing.

[0033] The adjustment block 534 is slidably fitted inside the mounting plate 55, the adjustment block 534 is supported at the bottom of the wheel hub, and the pad 535 is frictionally fitted with the top of the frame plate 3. The pad 535 at the bottom of the clamping block 532 is parallel to the frame plate 3 and supported at the bottom side of the wheel hub to maintain the stability of the wheel hub when rotating; the adjustment block 534 is slidably fitted with the mounting plate 55, when the motor 6 drives the wheel hub to rotate, the adjustment block 534 is thrown outward by the inertia generated by the rotation, and slides to the outermost side of the mounting plate 55, so that the clamping block 532 in the wheel hub is more closely fitted with the inner wall of the wheel hub cavity, and the clamping block 532 and the clamping rod 533 are prevented from loosening in the wheel hub cavity.

[0034] The third embodiment is based on the first and second embodiments. Figures 8 to 9As shown, the bottom stabilizing member 52 includes a fixing plate 521, the inclined surface of the fixing plate 521 is provided with a mounting groove 525, a clamping block 523 is fixedly mounted on the surface of the mounting groove 525, and a pad 524 is sleeved on the outer surface of the clamping block 523. Since the middle of the wheel hub is concave inward, when the wheel hub is sleeved on the surface of the shaft 51 and placed on the mounting plate 55, the middle of the bottom of the wheel hub squeezes the bottom stabilizing member 52, so that the bottom stabilizing member 52 is squeezed and concave downward, so that the bottom stabilizing member 52 is cushioned under the wheel hub to prevent the wheel hub from shaking during rotation and grinding, thereby affecting the grinding effect.

[0035] The fixing plate 521 is fixedly mounted on the outer surface of the shaft 51, and a curved cover 522 is fixedly mounted on the outer surface of the fixing plate 521. A segmented spring sheet 526 is arranged on the surface of the curved cover 522. The support block 523 penetrates the segmented spring sheet 526 and extends to the outside thereof. The segmented spring sheet 526 is pressed and adapted with the pad 524. The curved cover 522 is pressed by the wheel hub, and is concave downward and presses the pad 524 below. The segmented spring sheet 526 is deformed according to the shape of the wheel hub so as to fit the shape of the middle of the wheel hub and improve the stability during support.

[0036] When in use, the staff will put the wheel hub sleeve on the surface of the positioning protective part 5, so that the positioning protective part 5 can position and support the wheel hub, and then the staff will adjust the position of the grinding component 4 according to the wheel hub shaft diameter so that the grinding component 4 fits the wheel hub surface, and then the staff will start the motor 6 to rotate the output end of the motor 6 and drive the positioning protective part 5 to rotate, so that the wheel hub rotates with the positioning protective part 5 and generates friction with the grinding component 4, so that the grinding component 4 grinds the burrs on the wheel hub surface, and the burr debris that falls off during grinding falls onto the surface of the frame plate 3. When the frame plate 3 is cleaned after grinding, the staff will sweep the debris into the cleaning groove 7 to facilitate the collection and cleaning of the debris on the frame plate 3.

[0037] The staff puts the wheel hub on the surface of the shaft 51. At this time, the bottom of the wheel hub is placed above the mounting plate 55, and the bottom stabilizing member 52 is squeezed. Then the staff rotates the inner support member 53 upward so that the inner support member 53 is supported in the wheel hub cavity to support and position the wheel hub. Then the staff starts the motor 6 so that the output end of the motor 6 drives the through shaft 54 ​​and the shaft 51 to rotate, thereby causing the wheel hub to rotate and generate friction with the grinding assembly 4.

[0038] The staff rotates the clamp block 532 so that the clamp block 532 rotates upward inside the cushion block 535. At this time, the clamp block 532 drives the clamping rod 533 to rotate in the wheel hub cavity until it contacts the inner wall thereof. The clamp block 532 and the clamping rod 533 abut against both sides of the inner wall of the wheel hub cavity to support and limit the wheel hub, thereby preventing the wheel hub from shifting during rotation and polishing.

[0039] The pad 535 at the bottom of the clamping block 532 is in a parallel state with the frame plate 3 and is supported on the bottom side of the wheel hub to maintain the stability of the wheel hub during rotation; the adjusting block 534 and the mounting plate 55 are slidably adapted. When the motor 6 drives the wheel hub to rotate, the adjusting block 534 is thrown outward by the inertia generated by the rotation and slides to the outermost side of the mounting plate 55, so that the clamping block 532 in the wheel hub fits more closely with the inner wall of the wheel hub cavity, thereby preventing the clamping block 532 and the clamping rod 533 from loosening in the wheel hub cavity.

[0040] Since the middle of the wheel hub is recessed inward, when the wheel hub is sleeved on the surface of the shaft 51 and placed on the mounting plate 55, the middle of the bottom of the wheel hub squeezes the bottom stabilizing member 52, causing the bottom stabilizing member 52 to be squeezed and contracted downward, so that the bottom stabilizing member 52 is padded under the wheel hub to prevent shaking when the wheel hub is rotated for grinding, thereby affecting the grinding effect.

[0041] The curved cover 522 is squeezed by the wheel hub, concave downward and squeezes the pad 524 below. The segmented spring sheet 526 is deformed according to the shape of the wheel hub so as to fit the shape of the middle of the wheel hub and improve the stability during support.

[0042] The staff adjusts the position of the slider 44 in the guide rail 2 according to the hub shaft diameter, so that the polishing piece 42 fits better with the hub surface, and then the staff starts the motor 6, so that the motor 6 rotates to drive the hub to rotate so that the hub and the polishing piece 42 generate friction. When the hub rotates, it is squeezed with the polishing piece 42, so that the polishing piece 42 is squeezed and contacts the hub more closely, thereby increasing the contact area between the hub and the hub, so that the polishing force of the polishing piece 42 on the hub is enhanced.

[0043] Since the wheel hub is a round shaft structure, it needs to fit with its surface when it is polished. Before polishing, the staff moves the position of the slider 44 so that the arc-shaped covering frame 422 moves to the side close to the wheel hub, and the extrusion and fitting block 424 and the polishing block 423 are squeezed with the surface of the wheel hub, so that the fit is tighter during polishing, thereby improving the polishing efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
