Abstract

The invention relates to the field of abrasive grain flow polishing, and in particular relates to a precise turbulent processing method and a precise turbulent processing device for a titanium alloy artificial joint. The device comprises a constraint component, an electric control valve cabinet and an abrasive grain flow circulating system, wherein the constraint component is sleeved outside the artificial joint; a profiling runner is formed between the inner surface of the constraint component and the outer surface of the artificial joint; a plurality of groups of abrasive grain flow inlet / outlets are formed in the constraint component and are connected with the electric control valve cabinet through pipelines respectively; electric control elements which are used for controlling valves to be turned on, turned off and switched are arranged in the electric control valve cabinet; the electric control valve cabinet is connected with the abrasive grain flow circulating system. According to the method and the device, an abrasive grain flow controlled profiling runner is constructed through the constraint component, the abrasive grain flow inlet / outlets are formed in the constraint component, and a complicated curved surface is processed in a sectioning manner, so that the situation of non-uniform polishing caused by resistance of abrasive grain flow at an inflection point or a singular point of the curved surface is avoided; moreover, by virtue of the electric control valve cabinet, the conversion of any abrasive grain flow inlet / outlet and the flow control can be realized, so that all-directional three-dimensional processing is realized, the polishing efficiency is high, and the polishing effect is good.

Description

technical field [0001] The invention relates to the field of abrasive flow polishing processing, in particular to a method and device for turbulent flow precision processing of titanium alloy artificial joints. Background technique [0002] The smoothness of the artificial joint surface has a crucial impact on its function and service life. Therefore, the formed titanium alloy artificial joint prosthesis cannot be directly applied to the inside of the human body, and it needs to go through a series of grinding and polishing. Subsequent processing will finally obtain a high-precision and high-gloss surface, forming an artificial joint that fits well with human bones. [0003] The surface of the artificial joint is a complex curved surface with different curvatures, and the thermal conductivity and cutting performance of titanium alloy are poor. In the existing surface precision machining technology, most of the methods are difficult to apply. Since the abrasive flow can ...
