Description

technical field [0001] The invention belongs to the technical field of ceramic tube polishing, in particular to a single-drive high-efficiency and high-precision magnetorheological polishing machine for the outer surface of ceramic tubes. Background technique [0002] Polishing machines, also known as grinders, are often used for mechanical grinding, polishing and waxing. Its working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and friction with the surface to be polished, it can achieve the effect of removing paint surface pollution, oxide layer and shallow marks. The purpose is mostly continuously variable speed, which can be adjusted at any time according to the needs during construction. As the standard of polishing increases, magnetorheological polishing is gradually popularized. Magnetorheological polishing is an applica...

AI Technical Summary

Problems solved by technology

[0003] Due to the special shape and structure of the ceramic tube and the magnetorheological polishing is a new type of composite material polishing technology, there is little research and development on it. The traditional scheme adopts the annular radiation magnetization magnetic pole method and the electromagnet magnetization method, but the cost of radiation magnetization is very high , greatly increases the manufacturing cost of the magnetorheological polishing machine, and it is impossible to replace the magnetorheological polishing fluid, so this method is rarely used or even none; although the electromagnet magnetization method can achieve a good magnetorheological polishing fluid Replacement, but the two surfaces with better magnetic field generated by the electromagnet are the upper and lower toroidal surfaces, and the magnetic field strength of the inner and outer surfaces is very poor, which is far below the requirement of magnetic strength, which greatly reduces the efficiency and accuracy of magnetorheological polishing

[0004] In addition, due to the particularity of the ceramic tube material and shape, due to the brittleness and cylindrical shape of the ceramic tube material, and the magnetorheological polishing requires high precision, the positioning of the fixture is extremely important. The traditional fixture cannot meet its particularity at the same time, resulting in scratches on the surface More serious, the polishing accuracy is poor and the damage rate of the ceramic tube is high
