Turbulent flow simulation polishing device and method for artificial joint-like surface

Abstract

The invention discloses an artificial joint-like piece curved surface turbulence simulating polishing device and a method thereof. The device comprises a glass constraint component, a profiling electromagnetic wave heater, a temperature detection device, a supporting frame and an electromagnetic wave controller, wherein the glass constraint component is arranged outside an artificial joint-like piece in a sleeving way; the inner surface of the glass constraint component and the curved surface of the artificial joint-like piece form a profiling runner with uniform thickness; the profiling electromagnetic wave heater is arranged on one side of the glass constraint component; the profiling electromagnetic wave heater comprises an outer cover, heating sources, a concave lens and a convex lens; and each heating source of the profiling electromagnetic wave heater is electrically connected with the electromagnetic wave controller and is independently controlled by the electromagnetic wave controller. One heating source is placed on the side surface of the glass constraint component, the turbulence energy and the speed of abrasive flow cutting fluid are increased, and the linear loss and the head loss of the abrasive flow in the profiling runner are compensated, so that the whole processing effect is improved and the surface processing quality of the artificial joint-like piece is more uniform.

Description

Technical field [0001] The invention relates to the technical field of abrasive flow processing, and more specifically, to a turbulent flow simulation polishing device and method for the curved surface of an artificial joint part. Background technique [0002] Artificial joint is a kind of artificial organ designed to save the joint that has lost its function. It is one of the most effective artificial organs. The materials of artificial joints are generally metal alloys, among which special titanium alloys are close to human bones due to their biocompatibility, corrosion resistance, and elastic modulus, and are suitable for manufacturing artificial joints. The surface quality of artificial joints determines the properties of surface friction. The greater the roughness, the greater the probability of contact with surface asperities, resulting in increased adhesive wear. As we all know, titanium alloys have poor processing technology and are difficult to cut. However, titanium a...
