[0002] In the structural design of aerospace products, in addition to conventional structural parts, some structural parts with special structures are often encountered, such as long cylindrical parts with deep inner holes. Not only does the tail of the part have a groove shape, but the shape of the groove part is also more complicated. Its specific structure is as follows Figure 1 and Figure 2 As shown. For such parts, during the product anode cleaning process, due to the uneven distribution of power lines, it is easy to cause the parts to have uneven appearance colors after anode cleaning, and the appearance of the groove part is black, resulting in uneven overall appearance of the parts. If the existing conventional tooling is used, it is necessary to clean 2-3 times, and each cleaning time is 1-3 minutes. According to the existing cleaning method, it is easy to cause the installation size of the parts to change. The general size change varies between 0.008 and 0.02 mm. At the same time, because the parts are cleaned 2-3 times, the appearance of the parts is quite different. The outer circle of the parts is brighter, while the appearance of the groove part at the tail of the parts is whitish. In addition, with the existing conventional tooling, only 2 parts can be hung at a time, and only 2 parts can be cleaned each time, resulting in low efficiency of processing products and long processing time. Therefore, in view of the problem of uneven distribution of power lines during product anode cleaning, the appearance of the groove part is avoided to avoid blackening, so as to design a cleaning tool dedicated to long cylindrical parts, so as to improve production efficiency and reduce processing costs.

It can be seen from the two retrieved patent documents that they provide solutions to the anodizing of long cylindrical parts from different angles. However, from the disclosed contents, it can be seen that the supporting tooling and cleaning methods used are different from the cleaning tooling and cleaning methods used in this application.

[0027] This embodiment provides an anodizing cleaning method for cylindrical parts using the cleaning tool, and the anodizing cleaning method comprises the following steps: S1. The parts to be anodized are degreased, washed with hot water after degreasing, and finally dried; the specific degreasing method is to perform chemical degreasing in an alkaline solution to completely remove surface oil stains, the alkaline solution is a mixed solution containing 35-45g / L of sodium carbonate, 15-25g / L of sodium phosphate, 0.5-1.5g / L of sodium silicate and 25-35g / L of sodium hydroxide, and the degreasing time is 5 to 10min; and the hot water washing is to use pure water with a water temperature of 45 to 55°C in a washing tank for 2 to 4min, and the residual alkaline solution on the surface of the parts is removed by hot water washing; S2. Assemble the dried parts onto the cleaning tooling; the specific method of assembling the parts is to hang a part on the top of the first inclined portion 31 and the second inclined portion 32 of the auxiliary rack 3, respectively.

The specific structure after hanging is as follows Figure 5 As shown; S3. The assembled parts are placed in an anode cleaning tank for anodizing. The assembled parts are required to be placed vertically in the anode cleaning tank and then anodized. The tank temperature is controlled to be 50 to 60 ° C.

Take out the parts after anodizing treatment from the tank liquid, wash them in a clean water tank for 1 to 3 minutes at room temperature, and then wash them in a hot water tank for 1 to 3 minutes. Dry them after washing, and then remove the parts from the auxiliary hanger 3. Finally, inspect the parts. The specific inspection method, according to the existing method, is mainly the appearance of the arc surface of the part and the appearance of the groove at the tail of the part. Use standard appearance inspection methods to achieve consistency, and conduct statistical analysis on batch products.
[0028] Furthermore, the anodizing cleaning method described in this embodiment is adopted, and the drying in steps S1 and S4 is carried out by blowing the surface of the cylindrical parts with hot compressed air not exceeding 50°C that has been purified by an oil-water separator, so as to prevent the residual acid solution in the tank liquid from affecting the appearance quality of the film layer, and special attention is paid to drying the tail grooves and large holes; in addition, in the cleaning in step S4, pure water is used in both the clean water tank and the hot water tank, and the water temperature of the hot water tank is 60-80°C.
