Temperature control device and method for abrasive particle flow turbulent flow polishing equipment for similar artificial joints

Abstract

The invention discloses a temperature control device of pseudo artificial joint part abrasive flow turbulence polishing equipment temperature control device and a method thereof. The temperature control device comprises a glass constraint component, a temperature detection device, a three-freedom-degree moving device, an electromagnetic wave heater, a support frame, a gas membrane pump, a stirring device and an electromagnetic wave controller; the inner surface of the glass constraint component and the curve surface of the pseudo artificial joint part form a profiling flow passage with the uniform thickness; the profiling flow passage, the gas membrane pump and the stirrer form an abrasive flow circulation system through a pipeline; the temperature detection device is right aligned with the profiling flow passage; the three-freedom-degree moving device drives the electromagnetic wave heater to freely move in the three-dimensional space above the glass constraint component. Through the electromagnetic wave heater capable of moving along the three-freedom degree moving device which is arranged on the glass constraint component and is used for heating any position in the profiling flow passage; the turbulence kinetic energy and the speed of the abrasive flow cutting fluid in the corresponding heating position are respectively increased and accelerated, so that the integral processing effect is improved; the surface processing quality of the pseudo artificial joint part is more uniform.

Description

technical field [0001] The present invention relates to the technical field of abrasive particle flow polishing, and more specifically, relates to a temperature control device and a method thereof for artificial joint-like abrasive particle flow turbulent flow polishing equipment. 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, titani...
