Workbench structure for powder-spraying automobile wheel and powder-spraying method

Abstract

The invention discloses a workbench structure for powder-spraying an automobile wheel and a powder-spraying method, and relates to the field of automobile assembly. According to the workbench structure and the method, a support piece structure is arranged between the installation surface of the automobile wheel and a tray, then a powder-spraying operation is performed, and finally, powder is blown on the installation surface by an air-blowing device with an air output adjusting function from bolt holes in the automobile wheel. Therefore, the installation surface is protected, and the powder cannot be accumulated on the tray; and moreover, the tray is universal for wheels with different diameters, so that unnecessary actions of replacing the tray, scraping the installation surface powder and the like are avoided, and a great amount of money for buying equipment is saved, thus saving the manpower and material resources.

Description

technical field [0001] The invention relates to the field of automobile assembly, in particular to a method for protecting assembly surfaces of wheels after powder spraying. Background technique [0002] The mounting surface, center hole, and bolt hole of the wheel should be smooth and bright during assembly, and there should be no foreign matter on it, otherwise it will affect the safety of the vehicle. However, during the manufacturing process, there will be a lot of powder floating on the above three This poses a potential safety hazard to the driving of the car. Therefore, almost all wheel manufacturers must protect these three places to avoid dust from affecting safety. Current status of wheel dusting protection: There are two existing dusting methods, namely hanging dusting and horizontal dusting; there are generally three types of hanging dusting, hanging valve holes, center holes, and lower rims. Vacuum cleaners, gloves, air guns, etc. protect the installation surf...

Problems solved by technology

Although the effect is better, industrial vacuum cleaners must be used. Ordinary vacuum cleaners cannot work continuously for 24 hours. Even with industrial vacuum cleaners, in addition to high capital investment, continuous operation in a dusty environment for a long time will require frequent maintenance of the vacuum cleaner, which is costly and difficult. maintain

[0005] Some companies use separate lines for production, that is, the powder spraying line is separated from the baking line, but this involves the problem of line transfer. Manual line transfer will touch the powder on the wheels, which will affect the appearance.

The investment of manipulator line transfer is high and the maintenance cost is also high
