Abstract

The invention provides a complicated structure polishing method and device and belongs to the field of precise / ultra-precise processing. The method and device are realized based on shear thickening and chemical compound effect. The device comprises a polishing system, a polishing solution circulation device, a horizontal vibration device and a vertical vibration device. The method comprises the steps that, a polishing solution with shear thickening effect is prepared, chemical substance in the polishing solution is used for realizing rapid oxidation of the surface of a workpiece and generatingan easy-to-remove chemical reaction layer; the condition that the polishing solution can generate a shear thickening phenomenon is guaranteed in a manner of coupling of workpiece vibration and polishing solution rotation, and the chemical reaction layer is removed through micro cutting effect of a particle cluster; and a fresh surface is further subjected to chemical reaction and a chemical reaction layer is further removed. Through the shear thickening and chemical compound effect, the polishing efficiency can be greatly improved, and an ultra-smooth and little / zero-damage polished surface can be obtained. The method and device can be used for solving the problems that special positions of a complicated structure are difficult to polish, polishing evenness is poor, polishing efficiency is low, and a polished surface is of low quality.

Description

technical field [0001] The invention belongs to the field of precision / ultra-precision machining, and relates to a complex structure polishing method and device, in particular to a vibration polishing method and device for complex structures based on shear thickening and chemical composite effects. Background technique [0002] Various complex structures are widely used in aerospace, navigation, biological replacement, electrical appliances, weapons, automobiles, medical treatment and other fields. For example, aeroengine blades with complex structures can effectively improve working performance; complex structures or aspheric optical parts can effectively correct various types of aberrations, greatly improving the identification ability of instruments and equipment; engines with complex structures can effectively improve work efficiency ; At the same time, with the increasingly complex, high-precision, and miniaturized product shape design, more and more complex structures ...
