Abstract

A polishing method and device with a complex structure are realized based on shear thickening and chemical composite effects, and belong to the field of precision / ultra-precision machining. The device includes a polishing system, a polishing liquid circulation device, a horizontal vibration device and a vertical vibration device. Method By preparing a polishing liquid with shear thickening effect, the chemical substances in the polishing liquid are used to quickly oxidize the surface of the workpiece to form a chemical reaction layer that is easy to remove; the polishing liquid can be guaranteed to be produced by coupling the vibration of the workpiece and the rotational coupling of the polishing liquid. The phenomenon of shear thickening, where the chemically reactive layer is removed by the micromachining action of particle clusters; the fresh surface reacts with the chemical species again and is removed again. Through the effect of shear thickening and chemical compounding, the polishing efficiency can be greatly improved, and an ultra-smooth, less / no damage polishing surface can be obtained. The invention can be used to solve the problems of difficulty in polishing special positions of complicated structures, poor polishing uniformity, low polishing efficiency, low polished surface quality and the like.

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 ...
