The invention discloses a temperature-control abrasive particle flow humanoid artificial joint part curved surface turbulent machining device and method. The temperature-control abrasive particle flow humanoid artificial joint part curved surface turbulent machining device comprises a glass constraint component, an infrared window, a computer, an infrared temperature detector, an electromagnetic wave heating matrix, a stirrer, a gas membrane pump, a supporting frame and an electromagnetic wave controller, wherein a uniform-thickness profile flow channel is formed between the inner surface of the glass constraint component and the curved surface of a humanoid artificial joint part; the inlet of the profile flow channel is connected with the gas membrane pump, the stirrer and the outlet of the profile flow channel sequentially through a pipeline; the profile flow channel is exposed to the infrared temperature detector through the infrared window; and the electromagnetic wave heating matrix is mounted on the other side of the glass constraint component. The temperature-control abrasive particle flow humanoid artificial joint part curved surface turbulent machining device disclosed by the invention has the advantages that through arrangement of the electromagnetic wave heating matrix on one side of the glass constraint component, the turbulent energy and velocity of an abrasive particle flow cutting fluid are increased, so that the entire machining effect can be improved, the temperature of abrasive particle flow during an entire machining process can be kept constant, and the surface machining quality of the humanoid artificial joint part can be more uniform.

Description

technical field [0001] The invention relates to the technical field of abrasive flow polishing processing, and more specifically, relates to a temperature-controlled abrasive flow artificial joint surface turbulent flow processing device and method thereof. Background technique [0002] Artificial joint is an artificial organ designed by people to save joints that have lost their function. It has the best curative effect among artificial organs. The commonly used materials for artificial joints are metal alloys. Among them, special titanium alloys are suitable for the manufacture of artificial joints because of their biocompatibility, corrosion resistance, and elastic modulus, which are close to those of human bones. The surface quality of artificial joints determines the surface friction properties. The greater the roughness, the higher the contact probability of asperities on the surface, resulting in increased adhesive wear. As we all know, titanium alloy has poor proces...
