[0034] Please see Figures 1-6 A horizontal wheel hub end face cleaning device includes a base 1, on which a support frame 2 for placing the wheel hub and a cleaning device 3 for cleaning the wheel hub mounting end face are provided.

[0035] The support frame 2 is fixedly mounted at one end of the base 1, and the cleaning device 3 is mounted at the other end. The support frame 2 is used to stably support the wheel hub, providing a reliable foundation for the cleaning device 3 to clean the end face of the wheel hub.

[0036] The cleaning device 3 includes a base plate 301, a rotary motor 302, an extension shaft 303, and a brush head assembly 304. The rotary motor 302 is mounted on the base plate 301, and its shaft is connected to the extension shaft 303 via a coupling. The brush head assembly 304 is located at one end of the extension shaft 303 near the support frame 2. The rotary motor 302 drives the extension shaft 303 to rotate via the coupling, thereby driving the brush head assembly 304 to rotate, thus cleaning the end face of the wheel hub.

[0037] The brush head assembly 304 includes a fixed disc 304a, a movable disc 304b, a guide post 304c, a guide sleeve 304d, a spring 304e, an adjusting bolt 304f, bristles 304g, and a bristle mounting base 304j. The fixed disc 304a is fixedly mounted on the extension shaft 303, and the movable disc 304b is disposed between the fixed disc 304a and the support frame 2, and can move on the extension shaft 303. One end of the guide post 304c is fixedly connected to the side of the movable disc 304b near the fixed disc 304a, and the other end is connected to one end of the spring 304e; the end of the spring 304e away from the movable disc 304b is fixedly connected to the bottom of the adjusting bolt 304f. One end of the guide sleeve 304d is fixedly connected to the end of the fixed disk 304a near the movable disk 304b. The end of the guide post 304c away from the movable disk 304b is sleeved in the guide sleeve 304d and can move within the guide sleeve 304d. The spring 304e is sleeved in the guide sleeve 304d. The inner wall of the guide sleeve 304d near the fixed disk 304a has an internal thread 304h that matches the adjusting bolt 304f. By adjusting the adjusting bolt 304f, the compression degree of the spring 304e can be changed, thereby adjusting the pressure between the movable disk 304b and the wheel hub end face to adapt to the cleaning needs of wheel hub end faces of different specifications and materials. The bristles 304g are disposed in the bristle mounting seat 304j, which is fixedly mounted on the movable disk 304b. The rotating bristles 304g clean the wheel hub end face.

[0038] Furthermore, the lower end face of the base plate 301 is provided with a linear guide rail pair 4, the bottom end face of the linear guide rail pair 4 is fixedly connected to the upper end face of the base 1, and the slider on the linear guide rail pair 4 is fixedly connected to the lower end face of the base plate 301. The linear guide rail pair 4 enables the cleaning device 3 to move smoothly along the length direction of the base 1, facilitating the adjustment of the relative position between the cleaning device 3 and the hub, and improving the flexibility and adaptability of cleaning.

[0039] Furthermore, a set of linear guide rail pairs 4 are symmetrically arranged on the upper surface of the base 1. The symmetrical arrangement of the linear guide rail pairs 4 enables the cleaning device 3 to be more stable during movement, avoiding shaking or deviation and ensuring consistent cleaning results.

[0040] Furthermore, a propulsion cylinder 5 is provided between the two linear guide rail pairs 4. The cylinder body of the propulsion cylinder 5 is fixedly connected to the base 1, and its telescopic rod is connected to the lower end face of the base plate 301 through a connecting plate 6. The connecting plate 6 is fixedly connected to the lower end face of the base plate 301. The propulsion cylinder 5 can provide power for the movement of the sweeping device 3. By controlling the extension and retraction of the propulsion cylinder 5, the sweeping device 3 can be precisely controlled to move closer to or further away from the wheel hub, realizing automatic cleaning and improving cleaning efficiency.

[0041] Furthermore, the upper part of the support frame 2 is provided with an arc-shaped support surface 7, which is used to support the rim of the wheel hub being cleaned. The arc-shaped support surface 7 is adapted to the shape of the wheel hub rim, which can better fix the wheel hub, prevent the wheel hub from rolling or shifting during the cleaning process, and ensure the smooth progress of the cleaning work.

[0042] Furthermore, three guide posts 304c are arranged in a circular array. Each guide post 304c is equipped with a guide sleeve 304d and a spring 304e, and each spring 304e is equipped with an adjusting bolt 304f. The three guide posts 304c, guide sleeves 304d, springs 304e, and adjusting bolts 304f arranged in a circular array enable the movable disc 304b to be subjected to more even force, ensuring stable contact pressure between the brush head assembly 304 and the hub end face, thereby improving the cleaning effect. Furthermore, the extension shaft 303 and the arc-shaped support surface 7 are coaxially aligned. This arrangement ensures that the brush head assembly 304 remains perpendicular to the hub end face during rotational cleaning, guaranteeing comprehensive and uniform cleaning.

[0043] Furthermore, the bristle mounting base 304j has an annular structure with a groove 304k, and one end of each of the multiple bristles 304g is glued into the groove 304k. The bristle mounting base 304j is made of metal. The annular shape of the bristle mounting base 304j is adapted to the shape of the wheel hub end face, facilitating thorough cleaning of the wheel hub end face; the groove 304k can better fix the bristles 304g, preventing the bristles 304g from falling off during high-speed rotation; the metal bristle mounting base 304j has high strength and wear resistance, ensuring the service life of the bristle mounting base 304j.

[0044] Furthermore, the extension shaft is also provided with a seated bearing 8, which is inherently connected to the base plate 301, and the seated bearing 8 provides auxiliary support for the extension shaft 303.

[0045] Working principle:

[0046] The wheel hub is placed on the arc-shaped support surface 7 of the support bracket 2. The arc-shaped support surface 7 is adapted to the shape of the wheel hub rim, which can firmly fix the wheel hub and prevent the wheel hub from rolling or shifting during cleaning. According to the wheel hub specifications and materials, the adjusting bolt 304f in the brush head assembly 304 is rotated. Since the inner wall of the guide sleeve 304d near the fixed disc 304a has an internal thread 304h that matches the adjusting bolt 304f, the adjusting bolt 304f will move up and down in the guide sleeve 304d when it is rotated, thereby changing the compression degree of the spring 304e. This adjusts the pressure between the movable disc 304b and the end face of the wheel hub, ensuring that the brush head assembly 304 can contact the end face of the wheel hub with appropriate force for cleaning.

[0047] When the propulsion cylinder 5 is activated, its extension rod extends, driving the connecting plate 6 and the connected base plate 301, causing the entire sweeping device 3 to move towards the wheel hub along the linear guide rail pair 4 symmetrically arranged on the upper surface of the base 1. The linear guide rail pair 4 ensures the smoothness and precision of the sweeping device 3's movement, accurately delivering the brush head assembly 304 to a suitable position near the wheel hub end face.

[0048] When the brush head assembly 304 approaches the hub end face, the rotary motor 302 is activated. The shaft of the rotary motor 302 is connected to the extension shaft 303 via a coupling. When the rotary motor 302 rotates, it drives the extension shaft 303 to rotate via the coupling, thereby causing the brush head assembly 304, which is fixed on the extension shaft 303, to rotate at high speed. At this time, the bristles 304g in the bristle mounting seat 304j on the movable disc 304b rotate at high speed, cleaning the hub end face. During the cleaning process, if it is necessary to adjust the relative position between the cleaning device 3 and the hub, the extension and retraction of the propulsion cylinder 5 can be controlled again to ensure that all parts of the hub end face are effectively cleaned.

[0049] After the cleaning work is completed, first turn off the rotary motor 302 to stop the rotation of the brush head assembly 304. Then, start the propulsion cylinder 5 to retract its telescopic rod, driving the cleaning device 3 back to its original position along the linear guide 4. Finally, remove the cleaned hub from the support 2, completing one hub end face cleaning operation. The details of the embodiments are as follows, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
