Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic cleaning, and in particular to an automatic ultrasonic cleaning device and a cleaning method for a high-speed rail air-conditioning shell. Background Art

[0002] The principle of ultrasonic cleaning machine is that the high-frequency oscillation signal emitted by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated into the cleaning solvent, generating tens of thousands of tiny bubbles. The shock waves generated by the tiny bubbles destroy insoluble dirt and disperse the dirt in the cleaning agent. Ultrasonic cleaning is widely used in industry, national defense, biomedicine and other fields because of its fast cleaning speed, high cleaning accuracy, good cleaning effect, saving labor and cleaning agent, and good cleaning effect on deep holes, gaps and other difficult-to-clean areas.

[0003] At present, ultrasonic cleaning machines still have some shortcomings, such as low degree of automation, most of which are manual loading and unloading. For the cleaning of special workpieces, such as high-speed rail air-conditioning shells, since the workpieces themselves are relatively large, the current general tank cleaning machines are difficult to clean quickly and cleanly, and there are problems such as unstable cleaning quality, incomplete cleaning, and relatively wasteful of resources. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic ultrasonic cleaning device and a cleaning method for a high-speed railway air-conditioning shell, which has a high degree of automation, can achieve fast and clean cleaning, and has stable cleaning quality.

[0005] The present invention is achieved through the following technical solutions:

[0007] A loading assembly is arranged at the material port of the frame, comprising a material table fixed to the frame, and a bracket located on the material table and used to load the workpiece, wherein the bracket is movably connected to the material table through a first driving mechanism;

[0008] A lifting assembly is arranged in the frame, and can drive the bracket to enter and exit the ultrasonic cleaning tank, including a lifting frame that can accommodate the bracket, and a second driving mechanism is arranged in the lifting frame, which cooperates with the first driving mechanism at the material inlet to pull the bracket into the lifting frame, and the lifting frame is movably connected to the frame in the vertical direction through a third driving mechanism;

The wind shear cavity is arranged perpendicular to the moving direction of the bracket and opens toward the bracket.

[0010] Furthermore, the first driving mechanism can drive the bracket inlet and outlet, including a first chain and gears located at both ends of the first chain and cooperating with the first chain. A first shift block for shifting the bracket to move is fixed on the chain. The gear is rotatably installed on the material table through a mounting seat, and one of the gears is connected to a driving motor through a driving shaft.

[0011] The driving motor drives the driving shaft and the gear to rotate, and then drives the first chain to rotate. The first shift block is clamped with the bottom of the bracket, and the bracket is pushed forward to the gate for loading through the first shift block.

An ultrasonic component is provided in the ultrasonic cleaning tank 10, and the ultrasonic component includes a vibration box 37 and an ultrasonic generator in the vibration box 37. The ultrasonic generator generates supersonic power higher than 28KHZ, which is converted into mechanical vibrations of the same mechanical frequency by the transducer inside the vibration box 37 and transmitted into the ultrasonic cleaning tank 10. The ultrasonic waves are transmitted forward in a sparse and dense manner, generating countless tiny bubbles. These bubbles are formed and grown in the negative pressure area of ​​the longitudinal propagation of the ultrasonic wave, and quickly burst in the positive pressure area. The process of formation, growth, and rapid bursting of such tiny bubbles is called "cavitation effect". In the cavitation effect, the bursting of bubbles generates an instantaneous high pressure exceeding 10,000 atmospheres. The continuously generated instantaneous high pressure is like a series of small explosions that continuously impact oil stains, causing the stains to enter the cleaning liquid to complete ultrasonic cleaning. In the present invention, the vibration box is arranged on the bottom, front, and back sides of the ultrasonic cleaning tank 10, and comprehensive ultrasonic cleaning of the workpiece can be achieved.

By determining the height of the workpiece, the height at which the gate 9 is opened is controlled, so that different heights can be opened according to workpieces of different heights.
