Abstract

The invention relates to an engine connecting rod circulating cleaning device and method based on the laser cavitation effect, the engine connecting rod circulating cleaning device comprises a cleaning tank, a cleaning liquid circulating mechanism, a laser activation mechanism, a visual detection mechanism and a computer, the laser activation mechanism is arranged on the upper portion of the cleaning tank, and the laser activation unit emits laser to cleaning liquid of the cleaning tank; a laser cavitation bubble technology is adopted, a laser beam is applied to cleaning liquid, bubbles and cavitation phenomena are generated in the cleaning liquid, impact force is generated by utilizing the fact that cavitation bubbles crack in a connecting rod bushing gap, metal impurities mingled in the bushing gap are loosened, then the metal impurities fall off, and the cleaning purpose is achieved. And a computer is combined with a visual detection unit to carry out image acquisition and analysis on the motion form of the laser cavitation in the cleaning liquid and the distance between the laser cavitation and the connecting rod when the laser cavitation is broken, so that the whole-process monitoring on the laser cavitation cleaning connecting rod is realized, and the cleaning quality and efficiency are ensured.

Description

technical field [0001] The invention belongs to the technical field of automobile parts cleaning, and relates to an engine connecting rod cycle cleaning device and method based on laser cavitation. Background technique [0002] As an important part of the automobile engine, the connecting rod bears a high periodic load during work, and its force is very complex, so the assembly requirements for the connecting rod are very high. During a series of machining processes of the engine connecting rod, a large amount of residual metal debris and anti-rust oil dirt are left on the surface of the workpiece and in the gap, which is not only easy to scratch the inner surface of the large and small heads that require extremely high precision of the connecting rod, but also does not work well. It is beneficial to the heat transfer when the connecting rod is working, and seriously affects the working performance of the connecting rod, the engine and the crankshaft after assembly. Therefo...
