Description

Technical Field

[0001] This utility model relates to the field of wheel hub coating, specifically to a precision coating equipment for aluminum wheel hubs. Background Technology

[0002] Precision coating equipment for aluminum wheels is a collection of machines and accessories specifically designed for high-quality, refined coating operations on aluminum wheels. Its purpose is to provide a uniform, aesthetically pleasing coating with good protective properties to the surface of aluminum wheels, meeting requirements in terms of appearance, corrosion resistance, and wear resistance. When spraying wheels, the cylindrical side surface has a large area, necessitating repeated adjustments to the spraying surface. Alternatively, when the wheel is placed flat, manual operation of the spraying equipment is required, moving it around the wheel. However, such setups cannot guarantee uniformity and efficiency in spraying. Therefore, we have proposed a precision coating equipment for aluminum wheels. Utility Model Content

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.

[0023] Please see Figure 1-5 A precision coating device for aluminum wheel hubs includes a circular outer shell 1. An annular protrusion 2 is integrally formed on the top side of the circular outer shell 1. A displacement component 3, capable of moving around the annular protrusion 2, is mounted on the annular protrusion 2. A vertical plate 4 is mounted on one end of the displacement component 3 inside the annular protrusion 2. Multiple spray heads 21 are equidistantly arranged on the side wall of the vertical plate 4 corresponding to the center point of the annular protrusion 2. A vertical rod 6 is fixedly installed inside the annular protrusion 2. A load-bearing fixing structure is provided at the top of the vertical rod 6 to fix the wheel hub. The wheel hub is placed on the load-bearing fixing structure for placement and fixing. Then, the displacement component 3 is activated, rotating around the periphery of the wheel hub. Subsequently, the spray heads 21 are connected to the spraying equipment, and the coating is sprayed out through the spray heads 21, then sprayed around the wheel hub. This device can ensure the accuracy, uniformity, and efficiency of the spraying, precisely control the movement trajectory of the spray heads 21, and perform all-round, multi-layer spraying operations on the side of the aluminum wheel hub. It can adapt to aluminum wheel hubs of different sizes and shapes and can operate stably in complex working environments.

[0024] Furthermore, the displacement component 3 includes a moving plate 16, a second motor 17, and a second gear 20. The top of the annular protrusion 2 is provided with an annular groove 14. Multiple sets of teeth 15 are equidistantly arranged on the inner wall of the side of the annular groove 14 near the center point. The moving plate 16 is provided on the top of the annular protrusion 2. The second motor 17 is fixedly installed on the top of the moving plate 16. The output shaft of the second motor 17 extends into the interior of the annular groove 14. The output shaft of the second motor 17 is fixedly installed with the second gear 20. The second gear 20 meshes with the teeth 15. The moving plate 16 is fixedly connected to the vertical plate 4. When spraying is required, the second motor 17 starts and drives the second gear 20 to rotate. At this time, due to the meshing, the moving plate 16 will move around the annular protrusion 2, thereby driving the vertical plate 4 to move, realizing the rotational spraying around the hub.

[0025] Furthermore, multiple sets of T-shaped grooves 19 are equidistantly formed on the top of the annular protrusion 2, and a T-shaped protrusion 18 is integrally formed on the bottom of the movable plate 16 corresponding to the position of the T-shaped groove 19. The T-shaped protrusion 18 and the T-shaped groove 19 are slidably engaged together.

[0026] Furthermore, the supporting and fixing structure includes a clamping component and a driving component. A rectangular block 7 is provided at the top of the vertical rod 6. A groove 8 is provided on the rectangular block 7. The clamping component is located inside the groove 8. The driving component is connected to the clamping component.

[0027] Furthermore, the clamping assembly includes two racks 9 and a bonding block 5 disposed at one end of the two racks 9 facing away from each other. The bonding block 5 is made of rubber. The racks 9 are respectively bonded to the inner walls of the two sides of the groove 8, and the two ends of the racks 9 facing away from each other extend to the outside of the groove 8.

[0028] Furthermore, an inner wall groove 10 is formed on the inner wall of the groove 8, and a strip-shaped protrusion 11 is integrally formed on the rack 9 at the position corresponding to the inner wall groove 10. The strip-shaped protrusion 11 is slidably engaged with the inner wall groove 10.

[0029] Furthermore, the drive assembly includes a motor 12 fixedly installed inside the vertical rod 6 and a gear 13 installed on the output shaft of the motor 12. The gear 13 meshes with the racks 9 on both sides. When it is necessary to support and fix the hub, the inner end face of the hub is placed against the rectangular block 7. Then the motor 12 is started and rotated, driving the gear 13. At this time, the gear 13 drives the ends of the two racks 9 with the bonding blocks 5 to move to opposite sides. When the bonding blocks 5 are attached to the inner wall of the hub, the hub can be clamped and fixed from the inside, maintaining the stability of the hub. This device can be adaptively fixed according to the size of the hub to be sprayed, ensuring the stability of the hub when spraying hubs of different sizes.

[0030] Working principle: When it is necessary to support and fix the wheel hub, place the inner end face of the wheel hub on the rectangular block 7, and then start motor 12. Motor 12 rotates and drives gear 13. At this time, gear 13 drives the two racks 9 with the end of the bonding block 5 installed to move to opposite sides. When the bonding block 5 is attached to the inner wall of the wheel hub, the wheel hub can be clamped and fixed from the inside. When it is necessary to spray paint, motor 217 starts and drives gear 220 to rotate. At this time, due to the meshing, the moving plate 16 will move around the annular protrusion 2, thereby driving the vertical plate 4 to move, realizing the rotational spraying around the wheel hub.
