Embodiment Construction

[0021] In this embodiment, laser is used to induce the generation of cavitation bubbles that originally caused side effects such as erosion damage to water conservancy machinery and equipment, and work efficiency is reduced. Cleansing and intensive life-extending treatments.

[0022] The present invention will be described in further detail below in conjunction with specific examples.

[0023] Such as figure 1 As shown, a laser cavitation cleaning and strengthening device for crankshaft oil holes includes a laser generating unit, a water tank 6 and a computer 13, the laser generating unit is located at the upper end of the working fluid carrier 6, and the laser generating unit includes a YAG laser 1. The beam expander 2, the total reflection mirror 3 and the beam conversion and adjustment device 4 are used to form a high-energy cavitation bubble that cleans and strengthens the inner wall of the oil hole. The working fluid carrier 6 is equipped with a working medium, preferab...

Abstract

The invention discloses a laser cavitation cleaning enhancement device for a crankshaft oil hole and a cleaning enhancement method of the laser cavitation cleaning enhancement device. The laser cavitation cleaning enhancement device comprises a laser generation unit, a movement module, a working solution carrier and a computer, wherein the laser generation unit is positioned at the upper end of the working liquid carrier; the working solution carrier is filled with a working medium; a first intelligent manipulator and a second intelligent manipulator are mounted in the working liquid carrier; a gas increasing machine is mounted at the bottom end of the working solution carrier; and the laser generation unit, the first intelligent manipulator, the second intelligent manipulator and the gas increasing machine are all connected with the computer. When the laser cavitation cleaning enhancement device is adopted for cleaning enhancement, the laser beam energy and the dimensionless distance are regulated to divide the main effect forms of cavitation bubbles into two modes: a shock wave A and a collapse flow B; the mode A is adopted for removing burrs and cutting chips remaining after machining at first, and then the mode B is adopted for performance enhancement on the cleaned inner wall of the crankshaft oil hole; and not only can the inner wall of the crankshaft oil hole, namely such a narrow channel, be effectively enhanced, but also the cleaning condition of the crankshaft oil hole can be greatly improved, and the crankshaft oil hole can be circularly and effectively cleaned.

Description

technical field [0001] The invention relates to a metal laser cavitation cleaning and strengthening device and a cleaning and strengthening method thereof, in particular to a laser cavitation cleaning and strengthening device for crankshaft oil holes and a cleaning and strengthening method thereof. Background technique [0002] In the liquid, when the laser power density exceeds the breakdown threshold of the liquid, the liquid medium is broken down, and a luminous plasma cavity is formed in the breakdown area. The plasma continues to absorb laser energy strongly, and the cavity expands rapidly to form a cavity. The pulsation of bubbles radiates pulsed sound waves into the liquid. This process is the phenomenon of "photocavitation". The photocavitation effect caused by the interaction between laser and liquid medium is a basic theoretical problem in the fields of laser medicine and underwater laser processing. The birth and development of cavitation depends on many complicat...
