Description

Technical Field

[0001] The invention relates to the technical field of surface spraying equipment, and in particular to a coating equipment for axle surface treatment. Background Art

[0002] The axle of a car (also called the axle) is connected to the frame through the suspension, and wheels are installed at both ends. The function of the axle is to bear the load of the car and maintain the normal driving of the car on the road. According to the different driving modes, the axle is also divided into four types: steering axle, driving axle, steering driving axle and supporting axle. Among them, the front-engine rear-drive car usually uses the steering axle as the front axle and the driving axle as the rear axle; while the front-engine front-drive car uses the steering driving axle as the front axle and the supporting axle as the rear axle.

[0003] The structure of the steering axle is relatively simple, mainly consisting of two steering knuckles and a crossbeam; the drive axle is mainly composed of a main reducer, differential, half-axles, and axle housing. Due to its more complex structure, the manufacturing process of the drive axle is more complicated than that of the steering axle, including: casting of the axle housing, hot rolling of the half-axle sleeve, assembly of the main reducer, differential and other components, and welding and fixing of related components.

[0004] Furthermore, since the axle is directly exposed to the air when working, and rainwater is easily splashed on the car chassis when the car wades through water, the complexity of the working environment makes the car axle extremely prone to rust and corrosion, affecting its normal service life. Therefore, in the axle manufacturing process, an anti-corrosion coating link is usually introduced, and a layer of coating is applied to the corrosion-prone parts of the inner and outer surfaces of the axle to increase the overall anti-rust and corrosion resistance of the axle.

[0005] However, due to the structural particularity of the axle itself, the following problems often occur when the existing spraying equipment is used for surface coating:

[0006] 1. The axle clamping installation is inconvenient.

[0007] 2. The continuity of the transfer between multiple links of the axle surface coating is poor, which affects the spraying efficiency.

[0008] 3. The spraying method is single, and it is difficult to achieve dead-angle spraying of different parts of the axle.

[0009] 4. Untimely drying will affect the overall spraying effect.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0011] In view of the defects in the prior art, the present invention provides a coating equipment for axle surface treatment, which is used to solve the problems of inconvenient axle clamping and installation, poor continuity of axle transfer between multiple links of surface coating, affecting spraying efficiency, single spraying method, difficulty in achieving dead-angle spraying of different parts of the axle, and affecting the overall spraying effect when the spraying equipment in traditional technology is used for rust-proof and corrosion-resistant coating of the drive axle surface.
