[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-5 An energy-saving coating equipment for automotive wheel hubs includes an operating table 1. A rotating placement shaft 11 is provided on the end face of the operating table 1. A dilution pad 12 is installed at the connection between the end face of the operating table 1 and the outer end of the rotating placement shaft 11. The end of the rotating placement shaft 11 is driven by a servo motor. A bracket 2 is installed on the upper end of the operating table 1. A hydraulic cylinder 3 is installed on the top of the bracket 2. A rubber positioning shaft 4 is installed on the output end of the hydraulic cylinder 3. A wheel hub-shaped nozzle 41 is installed on the outer end of the rubber positioning shaft 4. Multiple spray nozzles are provided on the end face of the wheel hub-shaped nozzle 41. A support ring 42 is provided on the upper end of the wheel hub-shaped nozzle 41. Multiple slots 43 are opened on the end face of the support ring 42. A spray cover 51 is installed on the upper end of the support ring 42. Multiple elastic blocks 52 that are adapted to the slots 43 are provided on the inner top surface of the spray cover 51.

[0015] The hydraulic cylinder 3 has an external thread 31 on the outer side of its output end. The output end of the hydraulic cylinder 3 is installed with the rubber positioning shaft 4 through a threaded connection. Different models of rubber positioning shafts 4 are installed through the threaded connection. The rubber positioning shaft 4 is integrated with the hub-type nozzle 41.

[0016] Meanwhile, a connecting pipe 44 is provided at the top of the rubber positioning shaft 4. The rubber positioning shaft 4 is connected to the paint tank through the connecting pipe 44. The rubber positioning shaft 4 is hollowly connected to the hub-type nozzle 41. The connecting pipe 44 can transport the material in the paint tank to each hub-type nozzle 41 for spraying.

[0017] Furthermore, the wheel hub to be painted is placed on the rotating placement shaft 11, with the inner side of the wheel hub placed on the outer boss of the rotating placement shaft 11, and the front side of the wheel hub placed on the rotating placement shaft 11. During the spraying process, the end of the rotating placement shaft 11 is connected to the output end of the servo motor and driven by the servo motor, and the rotating placement shaft 11 drives the wheel hub to be sprayed in a directional manner.

[0018] When the spray cover 51 is installed on the upper end of the hub-type nozzle 41, the elastic block 52 is installed in the slot 43. The spray cover 51 is installed in the slot 43 through the elastic block 52, which can adapt to different types of hub-type nozzles 41. The function of the spray cover 51 is to prevent the spray material from spreading everywhere during the spraying process, thereby causing waste of spray material.

[0019] Meanwhile, the elastic clip 52 is made of silicone material, and the inside of the clip 43 is rounded. The silicone material has good elasticity, which allows for relatively quick installation and removal of the spray cover 51.

[0020] In this embodiment, the hub to be sprayed is first placed on the raised rotating placement shaft 11, and the front of the hub is placed on the outer boss of the rotating placement shaft 11. A dilution pad 12 is installed at the connection between the end face of the operating table 1 and the outer end of the rotating placement shaft 11. Then, the rubber positioning shaft 4 is installed on the top hydraulic cylinder 3 of the bracket 2 at the upper end of the operating table 1. The output end of the hydraulic cylinder 3 is threaded with the rubber positioning shaft 4 through the outer external thread 31. The upper end of the rubber positioning shaft 4 is connected to the paint tank through the connecting pipe 44. A hub-type nozzle 41 is installed at the outer end of the rubber positioning shaft 4. A connecting seat is provided on the upper end face of the hub-type nozzle 41. A support ring 42 is provided on the upper end of the connecting seat. Multiple slots 43 are opened on the end face of the support ring 42, and a spraying cover 51 is installed in them. The spraying cover 51 is installed together with the slots 43 through the inner elastic block 52. Then, the controller on the side of the operating table 1 controls the hydraulic cylinder 3 with electrical signals. The hydraulic cylinder 3 drives the rubber positioning shaft 4 to move above the wheel hub. The front end of the rubber positioning shaft 4 positions the wheel hub. Then, the paint box is controlled by electrical signals to transport the material in the paint box to the wheel hub-type nozzle 41 through the connecting pipe 44. The spray nozzle installed on the end face of the wheel hub-type nozzle 41 sprays the material. At the same time, the spray cover 51 installed on the outside of the wheel hub-type nozzle 41 completely covers the upper end face of the wheel hub for spraying. Then, the controller controls the servo motor below the operating table 1. The servo motor drives the rotating placement shaft 11 to rotate, and the wheel hub above the rotating placement shaft 11 rotates to spray the material. After completion, the hydraulic cylinder 3 drives the rubber positioning shaft 4, the hub-type nozzle 41, and the spray hood 51 back to the origin.

[0021] In this invention, the wheel hub to be coated is placed on the rotating placement shaft 11, and then a wheel hub-type nozzle 41 adapted to the wheel hub is installed. A spray cover 51 is installed on the outer end of the wheel hub-type nozzle 41, so that the paint can be sprayed evenly and quickly on the wheel hub during the spraying process, which can avoid the waste of paint caused by long-term spraying.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
