Problems solved by technology

Among them, when ultrasonic and bubbling are used for cleaning, due to the dead corners of the structural parts and the internal structure, the cleaning effect of ultrasonic and bubbling cannot be fully exerted, and the cleaning efficiency is low; when pickling is used, due to the pores in some structural parts, residual The pickling liquid will cause corrosion to the material of the structural parts, and the pickling liquid after use will also cause adverse effects on the natural environment
In addition, when flushing with water or other cleaning solutions, due to the existence of complex structures, it is difficult to discharge impurities and the cleaning efficiency is low

Embodiment

[0020] refer to figure 1 , shows a schematic structural view of a cleaning system for the inner cavity and profile of complex components provided by the embodiment of the present invention.

[0021] Such as figure 1 with figure 2 As shown, the cleaning system provided by the embodiment of the present invention may include: a cleaning tank 1, an inner tank 2, a heating device 3, a circulation tank 4, an insulation layer 5, a cover plate 6, a material basket 7, an overflow port 8, and a slag receiving basket 9. Filter pump 10, ultrasonic vibration box 11, intake hose 12, exhaust hole 13, hot air blower 14, fan pipe 15, ultrasonic vibration plate 16, ultrasonic vibrator 17, ultrasonic generator 18, control electrical box 19, wires Hose 20, shell 21.

[0022] The cleaning system uses the synergy of ultrasonic cleaning and bubbling rinsing to clean the surface of the workpiece. The inner tank 2 of the cleaning tank 1 is equipped with a heating device 3, which can heat the clea...

example 1

[0036]In this embodiment, the workpiece to be cleaned is a metal grid support with vertical through holes. After wire cutting and grinding, a large amount of oil and metal chips are attached to the surface of the through holes. If the ultrasonic vibrating plate 16 is used alone for cleaning, most of the tiny bubbles produced by ultrasonic cavitation will rise vertically with the ultrasonic vibrating plate 16, and the through-hole profile to be cleaned is also perpendicular to the direction of the ultrasonic vibrating plate 16, so , only a small amount of air bubbles generated by cavitation act on the surface of the through hole. At this time, although the cleaning effect without visible residues can be achieved, after wiping the surface of the through-hole with a cotton cloth, a small amount of oil stains and metal chips will be found. When using this cleaning structure for cleaning, the workpiece to be cleaned can be placed in the material basket 7, and the distance between t...

example 2

[0038] In this embodiment, the size of the workpiece to be cleaned is 1000 mm long x 500 mm wide x 500 mm high, and has a through hole with a diameter of 300 mm in the longitudinal direction. The cleaning effect of the ultrasonic vibrating plate 16 only acts on the external profile of the workpiece, and other methods must be adopted for cleaning the internal profile, which consumes manpower and material resources. When using this cleaning structure for cleaning, the workpiece to be cleaned can be immersed in the cleaning solution, the ultrasonic vibration box 11 and the intake hose 12 are placed inside the through hole of the workpiece, and under the synergistic effect of cavitation bubbles and gas bubbling, Effective cleaning of the internal profile of the through hole. At the same time, driven by the bubbling, the material exchange rate between the cleaning liquid inside the workpiece and the outside is accelerated, and the peeled oil and metal chips can quickly overflow the...

Abstract

The invention discloses a cleaning system for an inner cavity and a molded surface of a complex component. The cleaning system comprises a cleaning tank, an inner tank, a heating device, a circulating tank, an overflow port, a slag receiving basket, a filter pump, an ultrasonic vibration box, an ultrasonic vibration plate, an ultrasonic vibrator and an ultrasonic generator, the inner tank is arranged in the cleaning tank, and the heating device is arranged in the inner tank; the overflow port is located at the upper end of the side of the cleaning tank, and cleaning liquid flows through the slag receiving basket from the overflow port to flow into the circulating tank under the action of the filter pump and flows back into the cleaning tank through the filter pump to form circulation; an ultrasonic vibrator is installed in the ultrasonic vibration box, the ultrasonic vibration box is connected with the ultrasonic generator, the ultrasonic vibration plate is connected with the cleaning tank, the ultrasonic vibrator is installed at the bottom of the ultrasonic vibration plate, and the interior and the exterior of a workpiece are cleaned at the same time through the synergistic effect of the ultrasonic vibration box and the ultrasonic vibration plate. The cleaning effect can be enhanced.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a cleaning system for inner cavities and profiles of complex components. Background technique [0002] In the subsequent assembly process of aerospace structural parts, various connection processes such as welding, riveting, and screwing are required. Therefore, efficient and reliable cleaning processes and equipment are required to improve their surface cleanliness. [0003] After aerospace structural parts undergo machining processes such as wire cutting, turning, and milling, a large amount of cutting fluid and metal debris will remain on the surface. At present, ultrasonic cleaning, bubbling rinsing and pickling are mostly used to clean the surface of structural parts. Among them, when using ultrasonic and bubbling cleaning, due to the dead angle of the structural parts and the internal structure, the cleaning effect of ultrasonic and bubbling cannot be fully exerted, and...
