A texture processing test device based on controllable cavitation technology

Abstract

The invention provides a texture processing test device based on controllable cavitation technology, which has the advantages of no thermal deformation, no secondary processing, no limitation of processing materials, and non-parallel contact secondary texture processing, including numerical control precision Moving platform, electromagnetic loading mechanism, water storage tank, reflective laser cavitation generator, rotary controllable diameter nozzle, texture processing monitoring and feedback control system, medium water generates a large amount of air after passing through the reflective laser cavitation generator The cavitation bubbles are transferred to the surface of the processed material through the rotary controllable nozzle, and the texture processing is carried out by using the crushing force of the cavitation bubbles. During the processing, the crushing force is controlled in real time by the texture processing monitoring and feedback control system, and at the same time The texturing at a given position of the workpiece is realized by the X‑Y direction CNC precision moving platform and the Z direction electromagnetic loading mechanism.

Description

technical field [0001] The invention belongs to the field of bearing surface processing test devices, in particular to a texture processing test device based on controllable cavitation technology. Background technique [0002] In recent years, surface texture technology has attracted extensive attention from scholars at home and abroad. This technology uses physical, chemical or mechanical methods to process specific distributed and discrete micro-geometric features (such as pits or grooves) on the surface of friction contact pairs, which can effectively reduce friction between friction pairs and reduce wear. and increase the surface bearing capacity. [0003] As one of the commonly used texture processing methods, laser surface texturing technology uses high-energy-density laser to vaporize the surface material of the workpiece at the gathering point to form the desired texture morphology. However, laser processing is a thermal process. Under the action of high-pressure s...
