Abstract

The invention provides an inner hole wall polishing device based on a non-Newtonian fluid shear thickening mechanism. The inner hole wall polishing device comprises a polishing pool, a polishing solution circulation system, a polishing tool and a workpiece clamp. A polishing solution is arranged in the polishing pool and is formed by adding abrasive particles or micro powder in non-Newtonian fluid having a shear thickening effect. The polishing tool is arranged in the polishing pool and a machining gap is kept between the polishing tool and an inner hole wall of a workpiece to be machined. The workpiece clamp is arranged below the polishing tool, and the polishing tool, the workpiece clamp and the workpiece to be machined are located below the liquid level of the polishing pool. The workpiece clamp is connected with a workpiece drive mechanism, and the polishing tool is connected with a polishing tool drive mechanism. A circulation inlet of the polishing solution circulation system is communicated with an outlet in the bottom of the polishing pool. A circulation outlet of the polishing solution circulation system is communicated with an inlet in the upper portion of the polishing pool. The inner hole wall polishing device based on the non-Newtonian fluid shear thickening mechanism is high in polishing efficiency, good in quality, low in cost, and simple in structure.

Description

technical field [0001] The invention relates to the field of ultra-precision machining, in particular to a polishing device for the inner wall of hole parts based on the non-Newtonian fluid shear thickening mechanism. Background technique [0002] With the development of my country's industry and the continuous improvement of the degree of mechanization, people have higher and higher requirements for the automation level, work efficiency and work precision of machinery, and the processing quality of parts will determine the work precision, performance and service life of a part . The above requirements are all based on the premise of improving the machining accuracy of parts and their surface quality. Since the 1980s, my country has carried out many explorations on polishing processing technology, especially the development of non-traditional polishing processing, such as computer-controlled surface forming, magnetic field-assisted polishing, abrasive flow polishing, and air...
