The hot air circulation fan 72 can discharge the heated gas in the hot air heater 71 into the drying station 7 to further dry the surface of the workpiece below;

[0020] Rinsing tanks 8 are respectively arranged inside the ultrasonic cleaning station 3, the bubble rinsing station 4 and the spray rinsing station 5. Ultrasonic vibration boxes 31 are fixedly installed at the bottom and side of the rinsing tank 8 inside the bubble rinsing station 4. Ultrasonic transducers are installed inside the ultrasonic vibration boxes 31. Six groups of bubble tubes are equidistantly arranged at the bottom of the rinsing tank 8 inside the spray rinsing station 5. Cylinder moving rinsing mechanisms 9 and support column moving rinsing mechanisms 91 are respectively installed on the inner side walls of the bubble rinsing station 4 and the spray rinsing station 5;

[0021] On the gantry trolley 2, the cylinder barrel and the strut in the aircraft landing gear components can be carried and conveyed through the workpiece basket 21. In cooperation with the electric track 12 and the elevator 120, the cylinder barrel and the strut can be respectively conveyed to the rinsing tank 8. Through the lifting cable of the elevator 120, the workpiece basket 21 is hoisted to the ultrasonic cleaning station 3. In the two groups of ultrasonic cleaning stations 3, ultrasonic waves can perform ultrasonic vibration cleaning on the workpieces in the rinsing tank 8. After ultrasonic cleaning, the workpiece baskets 21 are respectively further hoisted and conveyed to the bubbling rinsing station 4 and the spray rinsing station 5. Through the bubbling pipe in the bubbling rinsing station 4, compressed air is used to generate bubbles inside the rinsing tank 8 corresponding to the station, so as to further clean the workpieces in the workpiece basket 21. In the bubbling rinsing station 4 and the spray rinsing station 5, the nozzles in the cylinder barrel moving rinsing mechanism 9 and the strut moving rinsing mechanism 91 can move to further spray the cleaning liquid on the workpiece surface under the drive of the cylinder. In this way, the automatic cyclic conveying and cleaning of the aircraft landing gear components are realized, making the cleaning more thorough. When conveyed to the water blowing station 6 and the drying station 7, the air pump can be used to punch the air nozzles. Under the cooperation of the cylinder guide wheels, the cleaning liquid and a small amount of impurities on the workpiece surface can be cleaned, so that the cleaning liquid on the component surface is synchronously cleaned, making the cleaning steps simple and the operation convenient.

[0022] Among them, the support frame 11 is used to support and install the electric track 12 and the gantry trolley 2. The gantry trolley 2 is slidably installed on the electric track 12. The elevator 120 is also slidably installed on the electric track 12 synchronously. The elevator 120 is used to hoist the workpiece basket 21 on the gantry trolley 2. On the gantry trolley 2, the cylinder barrel and the strut in the aircraft landing gear components can be carried and conveyed through the workpiece basket 21. In cooperation with the electric track 12 and the elevator 120, the cylinder barrel and the strut can be respectively conveyed to the rinsing tank 8. Through the lifting cable of the elevator 120, the workpiece basket 21 is hoisted to the ultrasonic cleaning station 3.

[0023] Among them, the material basket placement grilles 81 are respectively fixedly installed in the two groups of ultrasonic cleaning stations 3, the bubbling rinsing station 4 and the spray rinsing station 5. The material basket placement grilles 81 are used to place the workpiece baskets 21. The electric heating tubes 82 of the water tank are also fixedly installed at the bottom of the material basket placement grilles 81 close to the two groups of ultrasonic cleaning stations 3, the bubbling rinsing station 4 and the spray rinsing station 5. Through the elevator 120, the workpiece basket 21 on the gantry trolley 2 can be hoisted onto the corresponding material basket placement grille 81. The cleaning liquid in the rinsing tank 8 in the ultrasonic cleaning station 3, the bubbling rinsing station 4 and the spray rinsing station 5 can be heated by the electric heating tubes 82 of the water tank, so as to achieve a better cleaning effect on the oil stains on the workpiece surface.

[0024] Among them, the ultrasonic wave generator 32 is fixedly installed at the top of the ultrasonic cleaning station 3. The ultrasonic wave generator 32 is electrically controlled by a single-chip microcomputer. In the two groups of ultrasonic cleaning stations 3, ultrasonic waves can perform ultrasonic vibration cleaning on the workpieces in the rinsing tank 8.

[0025] Among them, both the cylinder moving rinsing mechanism 9 and the support moving rinsing mechanism 91 include a centrifugal spray pump, a cylinder, and a spray pipe. The spray pipe is connected through the spray pump, and the cylinder is used to drive the spray pipe to move. The bubbling pipe in the bubbling rinsing station 4 uses compressed air pressure to bubble inside the rinsing tank 8 in the corresponding station, so as to further clean the workpieces in the workpiece basket 21. The nozzles in the cylinder moving rinsing mechanism 9 and the support moving rinsing mechanism 91 in the bubbling rinsing station 4 and the spray rinsing station 5 can move to further spray the cleaning liquid on the surface of the workpiece under the drive of the cylinder. In this way, the automatic cyclic conveying and cleaning of the aircraft landing gear components are realized, making the cleaning more thorough.

[0026] Among them, an electric control cabinet 10 is fixedly installed on one side of the cleaning machine enclosure 1, and an upper and lower workpiece platform 13 is also installed on one side of the cleaning machine enclosure 1. A mist processor 14 is fixedly installed on the top of the cleaning machine enclosure 1. The mist processor 14 includes a centrifugal fan and an air duct, and the gas in the cleaning machine enclosure 1 can be discharged through the air duct.

[0027] Working principle: When in use, first, the workpiece basket 21 on the gantry trolley 2 can carry and convey the cylinder and the support in the aircraft landing gear components. Under the cooperation of the electric track 12 and the elevator 120, the cylinder and the support can be respectively conveyed to the rinsing tank 8.

[0028] Then, the workpiece basket 21 is hoisted to the ultrasonic cleaning station 3 by the lifting cable of the elevator 120. The ultrasonic waves in the two groups of ultrasonic cleaning stations 3 can perform ultrasonic vibration cleaning on the workpieces in the rinsing tank 8. The workpiece baskets 21 after ultrasonic cleaning are respectively further hoisted and conveyed to the bubbling rinsing station 4 and the spray rinsing station 5. The bubbling pipe in the bubbling rinsing station 4 uses compressed air pressure to bubble inside the rinsing tank 8 in the corresponding station, so as to further clean the workpieces in the workpiece basket 21. The nozzles in the cylinder moving rinsing mechanism 9 and the support moving rinsing mechanism 91 in the bubbling rinsing station 4 and the spray rinsing station 5 can move to further spray the cleaning liquid on the surface of the workpiece under the drive of the cylinder. In this way, the automatic cyclic conveying and cleaning of the aircraft landing gear components are realized, making the cleaning more thorough.

[0029] Finally, when being conveyed to the water blowing station 6 and the drying station 7, the air pump can press the air nozzle. The air nozzle can clean the cleaning liquid and a small amount of impurities on the surface of the workpiece under the cooperation of the cylinder guide wheel. In this way, the cleaning liquid on the surface of the component is synchronously cleaned, making the cleaning steps simple and the operation convenient.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes and modifications can be made to these embodiments without departing from the principle of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
