Three-way fluid polishing device for curved surface of human body joint and control method thereof

Abstract

The invention discloses a three-way human body joint curved-surface fluid polishing device. The three-way human body joint curved-surface fluid polishing device comprises a processing passageway and a fluid main pipe, wherein soft abrasive particle flow which is formed by mixing abrasive particles and water is stored in the fluid main pipe, two ends of an inlet and an outlet of the processing passageway are respectively connected with a three-way connector, two ends of the fluid main pipe are respectively connected with the three-way connectors on two ends of the inlet and the outlet of the processing passageway by virtue of a first branch pipe, a second branch pipe, a third branch pipe and a fourth branch pipe, and the processing passageway, the first branch pipe, the second branch pipe, the third branch pipe, the fourth branch pipe and the fluid main pipe are connected together to form a closed fluid circulating system. The three-way human body joint curved-surface fluid polishing device is simple and compact in structure and low in production cost; by adopting the three-way fluid passageway, two sides of an artificial joint can be uniformly polished by virtue of the soft abrasive particle flow; the gas is used as the power source of the abrasive particle flow, so that the probability of the abrasive particles for colliding with a workpiece can be increased, and the processing efficiency is improved; the entire processing flow can be completely automatically controlled, and the restriction for polishing the artificial joint by utilizing a tool can be avoided.

Description

technical field [0001] The invention relates to the technical field of soft abrasive flow polishing, and more specifically, relates to a three-way fluid polishing device for curved surfaces of human joints and a control method thereof. Background technique [0002] Artificial joints are organs with joint functions. With the development of science and technology and the improvement of people's living standards, the demand for artificial joints will continue to expand. [0003] The titanium alloy artificial joint prosthesis after molding and sintering cannot be directly applied to the inside of the human body, and it needs to go through a series of subsequent processes such as grinding and polishing to finally obtain a smooth, uniform, high-quality surface and a good artificial joint with human bones. joint. The smoothness of the artificial joint surface has a crucial influence on its function and service life. Titanium alloys are widely used in the design of artificial join...

AI Technical Summary

Problems solved by technology

Titanium alloys are widely used in the design of artificial joints due to their high strength and low modulus. However, there are defects such as poor machinability and low thermal conductivity in the surface finishing of titanium alloys, and most of the artificial joint surfaces are complex curved surfaces. The polishing method is difficult to process some surfaces effectively. Nowadays, the polishing of artificial joints is mainly performed by hand, the polishing efficiency is low and the polishing quality is difficult to stabilize
