[0002] In the manufacturing process of automobile wheels, there is a painting process. Painting automobile wheels can change their appearance and enhance the overall aesthetics of the car. There are various methods for painting automobile wheels, and manual spray gun painting is one of them, which is suitable for small-batch production or personalized customization scenarios.

[0003] When manually spraying wheel rims with a spray gun, the car wheel rims are generally in a fixed position. The operator holds the spray gun and keeps it perpendicular to the rim surface, maintaining a stable spraying process by swinging their arm to control the movement of the spray gun. However, manually spraying wheel rims with a handheld spray gun can lead to errors in the movement of the spray gun, potentially resulting in an unstable distance between the spray gun and the rim. This can cause uneven coating thickness on the rim surface and prevents the spraying of different areas of the rim from being kept in a fixed position, thus presenting some drawbacks.

[0004] Existing handheld spray guns for painting wheel hubs have the problem that they do not maintain a fixed position to spray different parts of the wheel hub. To address this, this application proposes a vehicle wheel hub painting device. Summary of the Invention

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: an automotive wheel hub painting device, including a wheel hub painting gun 2, which is used in conjunction with an external paint supply device. The structure and usage method of the wheel hub painting gun 2 are existing technologies and will not be described in detail in this application. Figure 1In this designation, A represents the wheel hub. A connecting plate 21 is fitted onto the outer side of one end of the wheel hub spray gun 2. The connecting plate 21 is fixed to the wheel hub spray gun 2 with screws, and the connecting plate 21 is also fixed to the moving plate 131 with screws. This fixes the position of the wheel hub spray gun 2, preventing it from tilting or moving during the spraying process and ensuring that the distance between the wheel hub spray gun 2 and the wheel hub A remains constant. The spraying bracket includes a base plate 11, a fixed plate 12 perpendicular to the base plate 11, a partition plate 13, a drive motor 15 fixed to the fixed plate 12 with bolts, and a mounting base 14 fixedly connected to the output shaft of the drive motor 15. A suspension column 141 is bolted to the center of the partition 13. A movable plate 131 is slidably connected inside the partition 13. The wheel hub spray gun 2 is connected to the movable plate 131 as a whole. The wheel hub spray gun 2 and the movable plate 131 move in the same direction. When spraying wheel hub A, wheel hub A is placed outside the suspension column 141, so that wheel hub A is in a suspended state. Wheel hub A and wheel hub spray gun 2 are opposite each other. When the drive motor 15 runs, the drive motor 15 drives the mounting base 14 and wheel hub A to rotate. The angle of wheel hub A changes, and the wheel hub spray gun 2, which is in the open state, sprays paint onto the surface of the slowly rotating wheel hub A to achieve the desired effect. The effect of uniformly spraying paint onto the surface of wheel hub A; the limiting component includes a pull-out plate 51 that fits against the mounting base 14, a sliding rod 52 that is slidably connected to the mounting base 14, a connecting rod 53 of the vertical sliding rod 52, a limiting rod 54 of the vertical connecting rod 53, a telescopic rod 6 and a limiting cover 7 that are fixedly connected by screws. The limiting cover 7 is fitted onto the outside of wheel hub A to prevent the paint from spreading around the limiting cover 7. The limiting rod 54 passes through the telescopic rod 6 and limits the telescopic rod 6 and the limiting cover 7. There is friction between the sliding rod 52 and the mounting base 14, and there is friction between the limiting rod 54 and the telescopic rod 6. The limiting rod 54 and sliding rod 52 remain stable; the lifting assembly includes a lifting electric push rod 41 on the vertical base plate 11, a limiting plate 42 fixedly connected to the top of the lifting electric push rod 41, a guide rail 43 fixed to the limiting plate 42 by screws, and a limiting block 3 slidably connected to the guide rail 43. The guide rail 43 is limited by the limiting block 3, so that the limiting plate 42 remains stable. The lifting electric push rod 41 runs and is in a reciprocating motion state of extension and shortening, which can make the limiting plate 42 in a slow lifting state, and has the function of changing the position of the wheel hub spray gun 2, so that the wheel hub spray gun 2 sprays on different positions on the surface of the wheel hub A.

[0027] In this embodiment, the limiting rod 54 and the sliding rod 52 are parallel, the sliding rod 52 is perpendicular to the pull plate 51, and the connecting rod 53 is slidably connected to the mounting base 14. The pull plate 51 can be pulled outward, thereby changing the position of the limiting rod 54 and the sliding rod 52, which facilitates the extension and retraction of the telescopic rod 6 and changes the position of the limiting cover 7. The limiting cover 7 moves away from the outside of the hub A without affecting the removal of the hub A. The limiting cover 7 is a funnel-shaped conical structure. One end of the telescopic rod 6 is connected to the narrow end of the limiting cover 7. The telescopic rod 6 includes a fixed end that is fixedly connected to the mounting base 14 and a telescopic end that is connected to the limiting cover 7. The telescopic end is slidably connected to the fixed end. The surfaces of the telescopic end and the fixed end are provided with through holes through which the limiting rod 54 passes. The limiting rod 54 passes through the telescopic rod 6, and the telescopic rod 6 is limited, thereby keeping the limiting cover 7 stable.

[0028] In this embodiment, a circular hole a is provided at the center of the movable plate 131 for the wheel hub spray gun 2 to pass through. The wheel hub spray gun 2 passes through the movable plate 131, and the connecting plate 21 on the wheel hub spray gun 2 is connected to the movable plate 131 to form a whole. The wheel hub spray gun 2 and the movable plate 131 move in the same direction.

[0029] In this embodiment, the limiting plate 42 includes a horizontal plate b and a vertical plate c connected to the lifting electric push rod 41. The wheel hub spray gun 2 passes through the vertical plate c. The guide rail 43 is connected to the vertical plate c. The limiting block 3 is fixed to the corresponding partition plate 13 by screws. The limiting block 3 has a "T"-shaped rail groove. The "T"-shaped guide rail 43 is slidably connected to the limiting block 3. The guide rail 43 is limited by the limiting block 3, so that the limiting plate 42 remains stable. When the lifting electric push rod 41 is running and is in a reciprocating motion of extension and shortening, the limiting plate 42 can be in a slow lifting state, which has the function of changing the position of the wheel hub spray gun 2.

[0030] Working principle and usage process of this utility model:

[0031] When painting wheel hub A, place wheel hub A outside the suspension column 141 so that wheel hub A is in a suspended state, with wheel hub A and wheel hub painting gun 2 facing each other;

[0032] Move the position of the limiting cover 7 and shorten the telescopic rod 6. The limiting cover 7 is fitted onto the outside of the wheel hub A to limit the wheel hub A.

[0033] Move the position of the pull-out plate 51 to move the sliding rod 52, the connecting rod 53 and the limiting rod 54. The limiting rod 54 passes through the telescopic rod 6, and the telescopic rod 6 is limited, thereby keeping the limiting cover 7 stable.

[0034] When the drive motor 15 is running, the drive motor 15 drives the mounting base 14 and the wheel hub A to rotate, and the angle of the wheel hub A changes.

[0035] The wheel hub spray gun 2 is turned on and sprays paint onto the slowly rotating surface of wheel hub A to achieve a uniform spraying effect on the surface of wheel hub A.

[0036] The lifting electric actuator 41 operates and is in a reciprocating motion of extending and shortening, so that the limiting plate 42 is in a slow lifting state, which changes the position of the wheel hub spray gun 2, so that the wheel hub spray gun 2 sprays at different positions on the surface of the wheel hub A.

[0037] In summary, this application provides a spraying device that maintains a fixed position to spray different positions on a wheel hub. The wheel hub spray gun 2 is fixedly connected to the moving plate 131, and the distance between the wheel hub spray gun 2 and the wheel hub is fixed, which will not cause uneven spraying thickness. Under the action of the drive motor 15, the wheel hub rotates, and the surface of the slowly rotating wheel hub can be sprayed. Under the action of the lifting electric push rod 41, the wheel hub spray gun 2 is vertically lifted and lowered, and the wheel hub spray gun 2 sprays different positions on the surface of the wheel hub A.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
