Abstract

The invention discloses a rotary polishing device with a vane constraint component. The rotary polishing device comprises a box body and a cover body, 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 and can rotate around the axis; a sealed polishing chamber is formed between an inner cavity of the cover body and an inner cavity of the box body; vanes are uniformly distributed on the inner surface of the cover 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. According to the rotary 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 vanes are uniformly distributed on the inner surface of the cover body, the cover body can rotate under the driving of a motor, and the rotation direction of the workpiece is opposite to the rotation direction of the cover body, 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...
