Linear polishing machining method and device based on magneto-rheological effect

Abstract

The invention discloses a linear polishing machining method and device based on a magneto-rheological effect. By means of the method and device, a combined magneto-rheological polishing wheel is adopted as a polishing tool. The device comprises a machine tool body, a worktable, a working liquid circulation unit, a polishing unit and a workpiece clamping unit. The machining characteristics of high efficiency, flexibility, environment friendliness and the like of magneto-rheological polishing are applied to the polishing machining process of workpieces with two-dimensional curved surfaces, planes, simple compound face forms and the like, face machining is achieved from line machining, the defect that workpieces are machined in different times is overcome, finishing of workpieces is achieved, the requirements for attractiveness, glossiness and smoothness of workpieces are met, meanwhile, the yield is increased, the machining efficiency is improved, and the machining cost is reduced.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a magneto-rheological effect-based linear polishing method and a device thereof. Background technique [0002] At present, some workpieces on the market are composed of simple two-dimensional curved surfaces and planes. The surface treatment generally begins to use numerical control technology, robot technology, and traditional abrasive tools such as sandpaper and abrasive belts for single-machine combination, multi-station, and multi-process surface grinding and polishing, but A fatal flaw in the current grinding and polishing technology is that the entire workpiece surface cannot be processed at one time. It needs multiple splicing to complete the entire workpiece processing. There is always a tool mark interface, which finally makes it difficult to guarantee the integrity of the outer surface. Grinding and polishing to process stitching marks not only reduces efficiency...
