Among them, pre-assembly treatment, as an important link to ensure engine quality, includes three steps: cleaning, appearance inspection and anti-rust treatment. The cleaning process is particularly critical, and its main task is to remove oil and metal debris on the surface of parts to prevent pollutants from entering the engine and affecting its performance and service life.

[0028] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an efficient double cleaning system, which innovatively integrates two cleaning modes: high-pressure washing and centrifugal immersion. The system is mainly composed of core components such as a cleaning box, an isolation inner cylinder, a limiting mesh cylinder and a transfer tray. A vertical isolation inner cylinder and a limiting mesh cylinder are provided in the cleaning box, and the transfer tray can be lifted and lowered to realize the automatic transfer of parts between different cleaning processes, which significantly improves the cleaning efficiency.

[0029] In the high-pressure washing process, a circular water delivery pipe is installed on the outside of the cleaning box, and several horizontal diversion pipes are evenly distributed on its inner circle. The end of each diversion pipe is equipped with a booster nozzle. After the cleaning water is diverted by the water delivery pipe, it forms a high-pressure water flow through the booster nozzle to wash the parts on the transfer tray in all directions. In addition, the horizontal diversion pipe is connected to the water injection elbow, and its opening extends to the inside of the isolation inner cylinder to provide water for subsequent centrifugal immersion.

[0030] The centrifugal immersion process switches modes by moving the transfer tray downward. When the transfer tray is lowered to the bottom of the water injection elbow, the cleaning water is injected into the isolation inner cylinder. At this time, through the synergistic effect of the rotating drive motor and the transmission drive motor, the cleaning box and the transfer tray rotate in the opposite direction, and the centrifugal force is used to form a vortex to deeply clean the parts. After the cleaning is completed, the transfer tray can continue to descend to discharge the waste water, or rise to transfer the parts to the limited mesh cylinder area for secondary high-pressure washing to ensure the best cleaning effect.

[0031] The cleaning water supply system of the present invention adopts a modular design and is mainly composed of a water storage tank, a water supply pump, a transfer water pipe and a retractable pipe joint. Through the precise control of the electric telescopic cylinder, the pipe joint and the transfer water pipe can be quickly connected and separated, which not only ensures the continuous water supply during the cleaning process, but also ensures the freedom of rotation of the cleaning box. This design not only improves the reliability of the system, but also simplifies the operation process, and has significant practical value. BRIEF DESCRIPTION OF THE DRAWINGS
