Polishing method and device based on optical rheologic material

Abstract

The invention discloses a polishing method and device based on an optical rheologic material. The polishing method based on the optical rheologic material aims at overcoming the defects of poor stability of a polishing medium, low material removal rate, uncontrollable model and poor adaptability to a workpiece surface in the prior art. The method comprises the following steps that optical rheologic polishing bodies are placed in annular grooves of a loading disc and limited by meshes; the wavelength of light which irradiates on the optical rheologic polishing bodies is adjusted through light control devices, then the rigidity of the optical rheologic polishing bodies is adjusted, and process-control polishing on a complex mold surface is achieved. The invention further provides the polishing device based on the optical rheologic material. The device mainly comprises polishing main shafts, the loading disc, annular press covers, light sources, the light control devices of the light sources, the optical rheologic polishing bodies, circulation systems of the optical rheologic polishing bodies and the like. Light which is given out by the light sources irradiates on the polishing medium, the rigidity of the polishing medium is changed, and the polishing main shafts are used for adjusting the gestures of workpieces in contact with the polishing bodies. According to the polishing method and device, the material removal rate can be controlled by moving the light sources and the main shafts, and the method and device are suitable for precision machining of parts.

Description

technical field [0001] The invention relates to the field of polishing processing of complex curved surface parts, in particular to a polishing method and device based on optical rheological materials. Background technique [0002] Polishing is often the use of polishing tools or other polishing media to modify the surface of the workpiece. It is the last process of part processing and plays a vital role in the quality of parts. The increase in demand for ultra-precision products and parts such as tiny aspheric surfaces, tiny nozzles, and tiny molds has posed a huge challenge to polishing technology. The polishing of such parts with complex surfaces is usually polished by free abrasive grain impact, abrasive grain flow scraping, etc. method, but the polishing process is uncontrollable and highly dependent on people, making it difficult to obtain high-precision surface quality. New polishing technologies such as magnetorheological polishing and electrorheological polishing h...
