Universal mounting system for aircraft skin anodizing and painting and its transfer method

Abstract

The invention relates to a universal hanging system for anodizing and paint spraying of aircraft skins. The system mainly comprises a skin frame, a transfer trolley and two paint spraying carts. The skin frame is formed by movable connection of two parallel hanging crossbeams and two aluminum vertical columns in vertical arrangement, detachable wheels are movably connected to the bottoms of the aluminum vertical columns, and the top of each aluminum vertical column is provided with a limiting plate. The transfer trolley is in a rectangular frame structure, upper slide ways are matched with the limiting plates, and lower slide ways are matched with the detachable wheels to form a transfer system. Each paint spraying cart is in a plate structure with moving wheels, the upper surface of each paint spraying cart is provided with limiting slide ways, positioning lugs adjustable in position are connected with a handrail cross rod at the end of each plate structure, and the two symmetrical paint spraying carts and the skin frame arranged on the limiting slide ways form a paint spraying system. The hanging system has the advantages that scrapping caused by creases of the skins in an anodizing and paint spraying process can be avoided, two-sided paint spaying of skin parts can be completed by one-time spraying, and accordingly paint spraying efficiency is improved.

Description

technical field [0001] The invention relates to a general mounting system for aircraft skin anodization and painting and a transfer method thereof, which are used for mounting and carrying aircraft aluminum alloy skin anodization and painting processes. Background technique [0002] Aluminum alloy skins are widely used in the modern aircraft manufacturing industry. Aluminum alloy skins are usually anodized and painted to obtain good corrosion resistance and appearance. However, due to the large size, small thickness, poor rigidity and smooth curved surface of the aluminum alloy skin, it is easy to scrap the skin due to accidental bending during the manufacturing process. Especially in the process of anodizing and painting the aluminum alloy skin, if it is improperly installed and transported, it is easy to cause partial shaking and bending of the skin during parts transfer (especially when entering and exiting the liquid tank) and handling, forming irreversible damage.

Problems solved by technology

[0004] (1) Due to the large area of ​​the skin, when it enters the liquid tank for processing, it will be subject to a large buoyancy when it falls, causing the lower part of the skin to float up, resulting in creases on the skin;

[0005] (2) Because the bracket is used to support the skin during painting, after one side of the skin is painted, it must be dried before painting the other side. The painting process takes a long time, requires many types of tooling, and occupies a large area;

[0006] (3) During the movement of the skin between different processes, because there is no protection means, it is easy to accidentally shake the skin and cause creases, which will lead to the scrapping of the skin;

[0007] (4) The existing skin spraying method uses only horizontal or vertical surfaces for the spray booth and oven, which leads to low space utilization and low production efficiency
