Abstract

The invention relates to the field of abrasive grain flow polishing, and in particular relates to an abrasive grain flow polishing device for a titanium alloy artificial joint. The abrasive grain flow polishing device comprises a box body, a cover body and a vane wheel, wherein a rotary device is arranged in the center of the box body; a workpiece is arranged on the rotary device; the cover body is sleeved above the box body; a sealed polishing chamber is formed between inner cavities of the cover body and the box body; an abrasive grain flow incoming port and an abrasive grain flow outgoing port are formed in two sides of the box body respectively and are communicated with the polishing chamber; the vane wheel is arranged in the polishing chamber, is positioned above the workpiece and can rotate around a rotary shaft. According to the abrasive grain flow polishing device, an abrasive grain flow runner is formed in the polishing chamber, the rotary device in the box body can drive the workpiece to rotate, the vane wheel is arranged above the polishing chamber and can rotate under the driving of a motor, and the rotation direction of the vane wheel is opposite to the rotation direction of the workpiece, so that grinding liquid in the polishing chamber performs relatively disordered motion, small-force micro-cutting on the surface is realized, the mirror-level surface roughness is achieved, and the device is good in polishing effect and high in accuracy.

Description

technical field [0001] The invention relates to the field of abrasive flow polishing processing, in particular to an abrasive flow polishing processing device for a titanium alloy artificial joint. Background technique [0002] As an implant device with joint function, artificial joints have been widely used in medicine. The metal parts of early artificial joints were made of stainless steel. With the advancement of technology, cobalt alloy materials have better corrosion resistance , wear resistance and mechanical properties have been applied. In recent years, titanium and titanium alloy materials have been developed. Titanium-containing materials are not only corrosion-resistant, but also have good strength and small specific gravity. They are easier to grow together with human bone and have good biological properties. compatibility, it is an ideal artificial joint material. [0003] The smoothness of the artificial joint surface has a crucial impact on its function and s...
