Description

Technical Field

[0001] This utility model relates to the field of automotive parts cleaning technology, specifically to a device for cleaning the surface of automotive wheel hubs. Background Technology

[0002] In modern transportation systems, automobiles, as vital means of transport, require meticulous maintenance of both performance and appearance. The wheel hub, a key component connecting the vehicle to the ground, supporting the body, and transmitting power, not only performs crucial mechanical functions but also plays a significant role in the vehicle's exterior design. However, during daily use, the wheel hub surface easily accumulates dust, mud, grease, brake dust, and various corrosive substances. This grime not only affects the vehicle's aesthetics but can also corrode the wheel hub material, impacting its lifespan and driving safety. Existing wheel hub surface cleaning devices generally meet daily needs, but some shortcomings still require improvement.

[0003] Existing wheel hub cleaning machines have fixed brush positions. Because the brush positions are fixed, the cleaning range formed by rotation is also limited. When the wheel hub size does not match the design size of the cleaning brush, the cleaning area cannot completely cover the wheel surface, resulting in incomplete cleaning and leaving stains or dead corners. To address this issue, we propose a car wheel hub surface cleaning device. Utility Model Content

[0004] The purpose of this invention is to provide a device for cleaning the surface of automobile wheel hubs to solve the problems mentioned in the background art.

A threaded rod is provided on the surface of the slider in the guide groove. A threaded block is threadedly connected to the threaded rod. Multiple sets of limiting grooves are opened on the surface of the fixing plate corresponding to the rear surface of the threaded block.

[0006] As a further preferred embodiment of this technical solution, the limiting groove is provided in four sets, and the four sets of limiting grooves are all equally spaced on the outer wall of the fixed plate.

[0007] As a further preferred embodiment of this technical solution, two sets of braking blocks are symmetrically arranged on the front surface of each threaded block, and the two sets of braking blocks are combined with the threaded block in a C-shaped design.

[0008] As a further preferred embodiment of this technical solution, the slider is T-shaped, and the groove is formed as a through hole adapted to the slider.

[0009] As a further preferred embodiment of this technical solution, the clamping assembly includes a movable chamber disposed on the worktable surface behind the wheel hub. A second self-locking motor is provided on the top of the movable chamber. A bidirectional lead screw is provided at the output end of the second self-locking motor, and the bidirectional lead screw rotates within the movable chamber. Two sets of transmission blocks are threaded onto the bidirectional lead screw. Each transmission block has a connecting seat at its front end.

[0011] As a further preferred embodiment of this technical solution, the slide plate is designed in a cross shape, and the fixing frame has countersunk holes that are adapted to the slide plate.

[0012] This utility model provides a device for cleaning the surface of automobile wheel hubs, which has the following beneficial effects:

[0013] 1. This utility model uses a slider to slide back and forth in a groove, which drives the cleaning brush to move. Then, by rotating a threaded block on a threaded rod, the threaded block is rotated into any set of limiting grooves, thereby achieving the purpose of adjusting the position of the cleaning brush. This allows the cleaning brush to be used for cleaning wheel hubs of different sizes and effectively improves the cleaning efficiency of the cleaning brush. At the same time, the slider sliding out of the groove also makes it easy for workers to disassemble and assemble the cleaning brush.

[0014] 2. This utility model uses a second self-locking motor to drive a bidirectional lead screw to rotate within the movable chamber. The rotating bidirectional lead screw acts on two sets of transmission blocks, causing the two sets of transmission blocks to converge towards the center of the bidirectional lead screw. As the transmission blocks move, the connecting seat and clamping plate synchronously drive the anti-slip pad to clamp the wheel hub. Then, the cleaning brush clamps the wheel hub, thus achieving the purpose of clamping and cleaning wheel hubs of different sizes. The anti-slip pad rotates within the bearing, and the spring's restoring force drives the sliding plate to return to its original position on the connecting rod, causing the insertion rod to insert into the slot, thereby fixing the wheel hub in a lateral position. The cleaning brush then rotates and adjusts the wheel hub, enabling the cleaning brush to clean multiple surfaces of the wheel hub, thereby improving the cleaning efficiency and cleaning effect of the cleaning brush.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1 to 6 As shown in this embodiment, a car wheel hub surface cleaning device includes a workbench 1, a wheel hub 2, and cleaning brushes 3. The wheel hub 2 is placed on the top of the workbench 1, and two sets of cleaning brushes 3 are provided on the workbench 1. An adjustment assembly 4 is provided on the top of the workbench 1, and the cleaning brushes 3 are connected to the adjustment assembly 4. A clamping assembly 5 is provided on the top surface of the workbench 1. The adjustment assembly 4 includes two sets of cylinders 41 symmetrically arranged on the surface of the workbench 1. Each cylinder 41 has a connecting plate 42 on its top, and a first self-locking electric... The output end of the first self-locking motor 43 is provided with a fixing plate 44. The upper and lower surfaces of the fixing plate 44 are symmetrically provided with sliding grooves 45. The sliding sliders 46 slide in the sliding grooves 45. The side surface of the sliders 46 facing the hub 2 is provided with a cleaning brush 3. The front surface of the fixing plate 44 is provided with a guide groove 47. The surface of the sliders 46 in the guide groove 47 is provided with a threaded rod 48. The threaded rod 48 is threadedly connected with a threaded block 49. The rear surface of the threaded block 49 is provided with multiple sets of limiting grooves 410 on the surface of the fixing plate 44 corresponding to the rear surface of the fixing plate 44.

[0024] In use, the slider 46 first slides in the groove 45, which moves the cleaning brush 3. At the same time, the slider 46 moves and simultaneously moves the threaded rod 48 in the guide groove 47 until the cleaning brush 3 is aligned with the size of the wheel hub. Then, the threaded block 49 is rotated on the threaded rod 48 so that the threaded block 49 is rotated into any set of connecting rods 510. Then, the cylinder 41 pushes the cleaning brush 3 to fit against the surface of the wheel hub 2 through the connecting plate 42. Then, the first self-locking motor 43 drives the cleaning brush 3 to rotate so that the cleaning brush 3 cleans the dust on the surface of the wheel hub 2.

[0025] In other embodiments, four sets of limiting grooves 410 are provided, and the four sets of limiting grooves 410 are all equally spaced on the outer wall of the fixing plate 44.

[0026] With this design, when the cleaning brush 3 drives the slider 46 to slide in the groove 45 for position adjustment, the slider 46 simultaneously drives the threaded rod 48 to slide in the guide groove 47, and the threaded block 49 on the threaded rod 48 is aligned with the four sets of limiting grooves 410 in sequence. Then, by rotating the threaded block 49 on the threaded rod 48, the threaded block 49 is rotated into the limiting groove 410, thereby achieving the purpose of adjusting the position of the cleaning brush 3, so that the cleaning brush 3 can make corresponding adjustments according to the wheel hub size.

[0027] In other embodiments, two sets of braking blocks 411 are symmetrically arranged on the front surface of the threaded block 49, and the two sets of braking blocks 411 and the threaded block 49 are combined in a C-shaped design.

[0028] This design allows workers to easily rotate the threaded block 49 using the brake block 411, preventing slippage when rotating the threaded block 49 and thus avoiding the need to reuse the threaded block 49.

[0029] In other embodiments, the slider 46 is T-shaped, and the groove 45 is formed as a through hole adapted to the slider 46;

[0030] This design allows the slider 46 to fit snugly against the groove 45, and the groove 45 to guide the slider 46, enabling the slider 46 to move back and forth in a straight line within the groove 45. This improves the stability of the slider 46 sliding within the groove 45 and prevents the cleaning brush 3 from shaking during use.

[0031] In other embodiments, the clamping assembly 5 includes a movable chamber 51 disposed on the surface of the worktable 1 behind the wheel hub 2. A second self-locking motor 52 is mounted on the top of the movable chamber 51. A bidirectional lead screw 53 is mounted at the output end of the second self-locking motor 52 and rotates within the movable chamber 51. Two sets of transmission blocks 54 are threaded onto the bidirectional lead screw 53. Each transmission block 54 has a connecting seat 55 at its front end. Bearings 56 are built into the side surface of the connecting seat 55 facing the wheel hub 2. The bearings 56 face the wheel hub 2... Each end is provided with a clamping plate 57. The surface of the clamping plate 57 facing the hub 2 is provided with an anti-slip pad 58. The right side surface of the connecting seat 55 is provided with a fixing frame 59. The inner wall of the fixing frame 59 is provided with a connecting rod 510. The connecting rod 510 is slidably mounted on a sliding plate 511. The surface of the connecting rod 510 on the right side of the sliding plate 511 is provided with a spring 512. The bottom of the sliding plate 511 is provided with an insertion rod 513. The left end surface of the insertion rod 513 is provided with four sets of slots 514 on the outer wall of the clamping plate 57.

[0032] In use, the second self-locking motor 52 first drives the bidirectional lead screw 53 to rotate within the movable chamber 51, causing the rotating bidirectional lead screw 53 to act on two sets of transmission blocks 54, bringing the two sets of transmission blocks 54 together towards the center of the bidirectional lead screw 53. Simultaneously, the transmission blocks 54 move, and the connecting seat 55 and clamping plate 57 synchronously drive the anti-slip pad 58 to clamp the wheel hub 2. Then, the cleaning brush 3 clamps the wheel hub 2. When cleaning the other side of the wheel hub 2 is required, the sliding plate 511 is first pulled, causing the sliding plate 511 to be positioned on the connecting rod 51. Slide the slide plate 511 onto the bearing 56 and compress the spring 512 until the slide plate 511 drives the insert rod 513 to slide out of the slot 514. Then, the clamping plate 57 rotates within the bearing 56, causing the hub 2 to rotate to a lateral position. At this time, another set of slots 514 on the clamping plate 57 aligns with the insert rod 513. Then release the slide plate 511 and use the restoring force of the spring 512 to push the slide plate 511 back to its original position within the fixed frame 59 until the insert rod 513 slides into the slot 514. Finally, clean the hub 2 with the cleaning brush 3.

[0033] In other embodiments, the top surface of the slide plate 511 is provided with a pull rod, and the pull rod is designed in a cylindrical shape;

[0034] This design facilitates the pulling operation of the slide plate 511 by the staff, preventing the slide plate 511 from slipping when being pulled, which would cause the spring 512 to push the slide plate 511 back to slide on the connecting rod 510, thus requiring the staff to pull the slide plate 511 repeatedly.

[0035] In other embodiments, the slide plate 511 is designed in a cross shape, and the fixing frame 59 has countersunk holes that are adapted to the slide plate 511.

[0036] This design allows the skateboard 511 to fit snugly against the fixed frame 59 from multiple sides, thus preventing the skateboard 511 from getting stuck inside the fixed frame 59 and unable to slide when the spring 512 pushes the skateboard 511 to slide inside the fixed frame 59.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
