Embodiment Construction

[0018] Step 1. The elastic polishing pad is elastically supported by the magnetorheological colloid or the magnetorheological foam material, and the initial stiffness of the magnetorheological colloid or the magnetorheological foam material is determined according to the process parameters of the polished part;

[0019] Magnetorheological colloid is a new type of magnetorheological material composed of magnetic particles, carrier liquid and polymer glue. The main difference between magnetorheological glue and magnetorheological fluid is that colloid is added to magnetorheological colloid, and colloid Part of the network structure formed in the carrier liquid is adsorbed on the surface of the magnetic particles, and part of it is dispersed in the carrier liquid. On the one hand, the gravity of the particles is evenly distributed in the matrix, thereby significantly improving their sedimentation stability; on the other hand, the particle surface The network structure increases th...

Abstract

The object of the present invention is to provide a flexible polishing method and device based on magnetorheological colloid or magnetorheological foam material, so as to solve the problems of low polishing efficiency and low precision in existing polishing methods. The method of the invention can change the rigidity characteristics of the magnetorheological colloid or magnetorheological foam material by means of an external magnetic field, adjust the contact pressure between the elastic polishing pad and the polished part, and realize the continuous polishing of the part by the elastic polishing pad, and at the same time respond due to the magnetic effect The time is fast, so that the rigidity dynamic response of the elastic polishing pad elastically supported by magnetorheological colloid or magnetorheological foam material is fast, thereby realizing the high-efficiency and high-precision polishing of parts by the flexible polishing device.

Description

technical field [0001] The invention relates to a polishing method and device for parts with complex curved surfaces. In particular, a flexible polishing method and device based on magnetorheological colloids or magnetorheological foam materials. technical background [0002] The flexible polishing technology currently being studied mainly refers to the airbag polishing technology. In 2000, Walker et al first proposed a rotary expansion and compliance polishing tool, referred to as SBCT, which was applied to the polishing of aspheric optical parts and achieved success. The tool is an airbag polishing tool. Based on the research results of Walker et al., Gao Bo et al. used improved SBCT polishing tools to polish on glass, and achieved remarkable results. But these polished objects are all optical components, the roughness of the rough itself is low, and the material removal rate is very low. Shiming et al. applied the airbag polishing technology to the polishing of metal ...
