[0002] The wheel hub is where the axle is mounted at the center of the wheel. Wheel hubs are prone to getting dirty, and if they are not cleaned for a long time, they may corrode and deform, leading to safety hazards. Therefore, during the wheel hub manufacturing process, their surface is usually sprayed. Spraying can protect the wheel hub from corrosion, extend its service life, and at the same time give the wheel hub different colors and effects, enhancing the visual effect and personalization of the vehicle. During spraying, the wheel hub needs to be suspended for a full-body spraying operation.
[0003] The shortcomings of existing technologies: The existing suspension devices for automotive wheel painting have poor versatility and cannot meet the needs of wheel rims of different sizes. During the fixing process, they can easily obstruct the surface of the wheel rim that needs to be painted, affecting the painting effect. At the same time, the fixed wheel rim cannot be rotated during the painting process, and the spray gun needs to be moved manually to paint other parts of the wheel rim, which is very inconvenient to use and can easily cause uneven painting. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a suspension device for automotive wheel hub painting, which solves the problems of poor versatility of the existing suspension devices, inability to meet the requirements of wheel hubs of different specifications and sizes, easy obstruction of the wheel hub, and the need for manual movement of the spray gun to spray other parts of the wheel hub during the painting process, which can easily cause uneven spraying.
[0005] This utility model provides the following technical solution: a suspension device for automotive wheel hub painting, including an operating table and a support plate fixedly connected to one side of its top end. A protective cover is fixedly installed in the middle of the top end of the operating table, and a suspension assembly for wheel hub suspension is provided in the middle of one end of the support plate.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The suspension device for automotive wheel hub painting involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] This utility model provides a suspension device for automotive wheel hub painting, such as... Figure 1 - Figure 4 As shown, it includes an operating platform 1 and a support plate 2 fixedly connected to one side of its top. A protective cover 3 is fixedly installed at the middle of the top of the operating platform 1. A suspension assembly 4 for wheel hub suspension is provided at the middle of one end of the support plate 2. Two exhaust pipes 9 are fixedly connected to the top of the protective cover 3.
[0022] Furthermore, such as Figure 2 As shown, the suspension assembly 4 includes a turntable 41 located in the middle of one end of the support plate 2. A positioning rod 42 is fixedly connected to the middle of the turntable 41. The wheel hub is suspended by the positioning rod 42. Four adjustment slots 43 are provided on the turntable 41. A slider 44 is movably connected to the inner cavity of the adjustment slot 43. A limit rod 45 is fixedly connected to one end of the slider 44. The position of the limit rod 45 is adjusted by sliding the slider 44 in the inner cavity of the adjustment slot 43.
[0023] Furthermore, such as Figure 2 As shown, one end of the turntable 41 has four mounting slots 46. The four adjustment slots 43 and the mounting slots 46 are arranged in a circular array. The position of the mounting slots 46 corresponds to the position of the adjustment slots 43. A cylinder 47 is fixedly installed in the inner cavity of the mounting slot 46. The extended end of the cylinder 47 is fixedly connected to the end of the slider 44 away from the limit rod 45. After the wheel hub is suspended by the positioning rod 42, the limit rod 45 is adjusted according to the specific position of the through hole on the surface of the wheel hub. The cylinder 47 is then activated. The extension and retraction of the extended end of the cylinder 47 drives the slider 44 to move in the inner cavity of the adjustment slot 43, so that the limit rod 45 is locked in the inner cavity of the through hole on the surface of the wheel hub, thus fixing the wheel hub. This method is applicable to wheel hubs of various specifications and sizes.
[0024] Furthermore, such as Figure 1As shown, both ends of the protective cover 3 are provided with insertion holes 5. The inner cavity of the insertion hole 5 is provided with a spray gun 6. The output end of the spray gun 6 is set towards the suspension assembly 4. After the wheel hub is fixed, the spray gun 6 is inserted into the inner cavity of the insertion hole 5 for fixation. At the same time, the input end of the spray gun 6 is connected to the output end of the external paint supply equipment, and the surface of the wheel hub is sprayed through the spray gun 6.
[0025] Furthermore, such as Figure 3 As shown, a motor 7 is fixedly connected to the other end of the support plate 2, and a connecting rod 8 is fixedly connected to the output end of the motor 7. The end of the connecting rod 8 away from the motor 7 is fixedly connected to the middle of the turntable 41. During the spraying process, the motor 7 is started, and the turntable 41 is driven to rotate by the motor 7, so that the wheel hub rotates at a uniform speed. During the rotation, the surface of the wheel hub is sprayed with the spray gun 6 to ensure the uniformity of the spraying on the surface of the wheel hub.
[0026] Furthermore, such as Figure 4 As shown, the top of the protective cover 3 is arc-shaped, and a fan 10 is fixedly installed in the middle of the inner cavity of the exhaust pipe 9. Since the spray gun 6 performs the spraying operation in the form of spray, the spray will fly around and cause environmental pollution. Therefore, the fan 10 is started during the spraying process so that the excess spray can drift towards the direction of the fan 10 and be discharged and treated in a concentrated manner through the exhaust pipe 9.
[0027] Furthermore, such as Figure 4 As shown, a storage slot 11 is provided at the top center of the operating table 1, and the inner cavity of the storage slot 11 is arc-shaped.
[0028] The working principle of this utility model is as follows: First, the wheel hub to be sprayed is placed in the inner cavity of the storage slot 11. Before spraying, the positioning rod 42 is inserted into the through hole in the middle of the wheel hub to suspend the wheel hub. Then, the limiting rod 45 is adjusted according to the specific position of the through hole on the surface of the wheel hub of different specifications and sizes. The cylinder 47 is started, and the extension and retraction of the cylinder 47 drives the slider 44 to move in the inner cavity of the adjustment slot 43, so that the limiting rod 45 moves in the inner cavity of the through hole on the surface of the wheel hub until the limiting rod 45 is locked. Then the cylinder 47 is closed, so that the device can be used for wheel hubs of various specifications and sizes. The wheel hub is fixed by the four limiting rods 45. After the wheel hub is fixed, the spraying operation is performed by inserting the spray gun 6. The inner cavity of the socket 5 is fixed, and the input end of the spray gun 6 is connected to the output end of the external paint supply equipment. The surface of the wheel hub is sprayed by the spray gun 6. During the spraying process, the motor 7 is started, and the turntable 41 is rotated by the motor 7, so that the wheel hub rotates at a uniform speed. During the rotation, the spray from the spray gun 6 sprays the surface of the wheel hub, ensuring the uniformity of the spraying on the surface of the wheel hub. Since the spray from the spray gun 6 will drift everywhere, the fan 10 is started at the same time as the spraying. The top of the protective cover 3 is set to be arc-shaped, which is conducive to the concentration of the spray. The excess spray generated by the spray gun 6 can drift towards the direction of the fan 10 and be discharged and treated through the exhaust pipe 9.
