Description

Technical Field

[0001] The invention relates to the technical field of aircraft wall panel anodizing and quick painting changeover, in particular to a clamp device and a clamping method for aircraft wall panel anodizing and quick painting changeover. Background Art

[0002] Aircraft siding is a key structural component in the overall structure of the aircraft. It bears the important task of bearing flight loads and aerodynamic loads. Anodizing is usually used to enhance the corrosion resistance and paint adhesion of siding, and spray painting is used to increase oil resistance and pollution resistance on the basis of obtaining the appearance. Due to the many features of siding parts, large area and thinness, and many depressions and grooves, it is easy to have accidents such as bumps and falls during the manufacturing process.

[0003] The traditional anodizing method is to use a single bell-shaped hanger to hang on a conductive rod, and after anodizing, the parts are removed and placed flat on a bracket with a matching shape for manual spraying of paint; if multiple wall panels need to be processed at the same time, the anodizing will be insufficient and the anodized film will be uneven due to the mutual obstruction between the wall panels, which will greatly affect the corrosion resistance and paint adhesion.

[0004] In the traditional flat painting method, after one side of the wall panel is painted, it must wait for it to dry before painting the other side, which takes up the painting space and oven space, and has low turnover efficiency, which is not in line with the concept of lean production. In addition, flat spraying requires higher control of the painting environment and the workers' painting skills, because flat laying makes it easier for small particles such as dust in the painting environment to settle on the surface. Workers must carefully handle sinking and grooves to prevent overspray, which will have a certain impact on product quality control. In the process of anodizing and painting, manual handling is frequently required. If there is no protection, parts will fall, resulting in damage to the size of the parts or scrapping, and there will be a risk of worker injury. Summary of the invention

[0005] In order to solve the above-mentioned technical problems existing in the prior art, the present invention provides a fixture device and a clamping method for rapid switching between anodizing and painting of aircraft wall panels. By increasing or decreasing the layout of the fixture device and using the lower-level assembly holes (surfaces) that do not require anodizing and painting, the anodizing function and the painting function can be switched conveniently and mutually auxiliary, multiple clamping can be achieved, the production cycle of wall panel parts can be shortened, the anodizing loading rate can be improved, the space and oven occupancy of the wall panels can be saved through vertical spraying, and the production efficiency can be effectively improved.
