[0028] Referring to Figures 1-3 The cleaning liquid circulating supply system 10 comprises a water tank 13 and a connecting pipe 3 connected between the water tank 13 and the cleaning device. The connecting pipe 3 is connected in series with a cleaning pump 15, a pressure reducing valve 16 and a precision filter 17. The water tank 13 is provided with an oil skimming mechanism. The part transport vehicle movable platform 35 is provided with a water receiving tray 36 below the part transport vehicle 9. The water receiving tray 36 can prevent residual cleaning liquid from leaking during the loading and unloading of parts and prevent cleaning liquid from leaking from the cleaning machine door during cleaning. The water outlet of the water receiving tray 36 is connected to the backflow port of the water tank 13. The backflow port is provided with a filtering mechanism (which can be a coarse filter screen 12). The cleaning liquid after cleaning the parts enters the water receiving tray 36 and then enters the water tank 13 through the backflow port, thereby realizing the recycling of the cleaning liquid through the backflow of the cleaning liquid. The water tank 13 is also provided with a drain valve 14. Opening the drain valve 14 can completely remove the cleaning liquid and sundries in the water tank 13.
[0029] Referring to Figure 8 (for convenience, the shell constituting the water tank 13 is not shown in the figure, only the frame is shown), specifically, the oil skimming mechanism comprises a partition plate 39 and an oil skimmer 11. The water tank 13 is divided into a left chamber 131, a middle chamber 132 and a right chamber 133 by two partition plates 39. The left chamber 131 is in communication with the lower part of the middle chamber 132 and is isolated from the upper part to isolate floating oil scum. The middle chamber 132 is in communication with the upper part of the right chamber 133 and is isolated from the lower part to prevent particulate matter from entering the right chamber 133. The backflow port of the water tank 13 is connected to the top of the left chamber 131. The oil skimmer 11 is installed on the top of the left chamber 131 to remove floating oil scum. The water inlet of the cleaning pump 15 is immersed in the right chamber 133.
[0030] The cleaning liquid is filtered in three stages during the recycling process: first, coarse filtering by a metal filter screen at the cleaning liquid backflow port; second, filtering by setting a partition plate in the cleaning liquid tank to remove floating oil scum and block particulate impurities; and third, precision filtering by a filter bag type precision filter 17 after the cleaning pump. The filter bag with different precision can be selected according to the needs.
[0031] Further, a heater 38 can be arranged in the middle chamber 132 of the water tank 13 to adjust the temperature of the cleaning liquid to improve the cleaning effect.
[0032] The lower layer and the middle layer of the cleaning machine body 1 are of the same size, and an adjustable foot 18 is installed at the bottom of the cleaning machine body 1 to support the entire machine body and accessories.
[0033] The cleaning machine body 1 is provided with a cleaning chamber 37 covering the cleaning area, and the cleaning device is located in the cleaning chamber 37. During the cleaning process, the cleaning part 7 is enclosed in the cleaning chamber 37, which can avoid liquid splashing.

Specifically, the cleaning machine body 1 is provided with a vertical cleaning machine door guide rail 23, and the cleaning machine door 6 is in sliding cooperation with the cleaning machine door guide rail 23. The cleaning machine body 1 is also provided with a cylinder mounting seat two 24, and a guide rod cylinder two 5 is installed on the cylinder mounting seat two 24. The cylinder arm of the guide rod cylinder two 5 is fixed on the cleaning machine door 6 to drive the cleaning machine door 6 to rise and fall, so as to realize the closing and opening of the cleaning chamber 37.
[0034] The part transport vehicle 9 includes a transport vehicle body 31, guide positioning rollers 30, a reversible handle 33 and support rollers 34 installed on the transport vehicle body 31. The guide positioning rollers 30 are installed on the side of the transport vehicle body 31, and the support rollers 34 are arranged at the bottom of the transport vehicle body 31. The part transport vehicle movable platform 35 is respectively provided with tracks or limiting members matched with the guide positioning rollers 30 and the support rollers 34. The main body of the part transport vehicle 9 is a flat plate composed of square tubes. During work, the part transport vehicle accurately sends the parts to the corresponding position below the cleaning tool, and at the same time, the reversible handle is pressed down. When the machine door is closed, the gap between the machine door and the reversible handle 33 is 2-3 mm, which prevents the part transport vehicle 9 from moving during work. The reversible handle 33 adopts a large chamfer design. Even if the part transport vehicle is not pushed to the correct position, it can also be pushed to the correct position by the falling cleaning machine door 6. When loading and unloading parts, the workpiece is moved out of the cleaning chamber, and the reversible handle is pressed down to fix the transport vehicle on the water pan of the cleaning machine body. The part transport vehicle 9 can be pulled by manpower, or by a cylinder or other power device according to needs. The material of the part positioning tool 32 on the part transport vehicle 9 is nylon, which can avoid scratching the parts.
