Method and device for turbulent precision machining of curved surface of titanium alloy artificial joint

Abstract

The invention discloses a titanium alloy artificial joint surface turbulence precision machining method and device. The titanium alloy artificial joint surface turbulence precision machining method is characterized in that a special square machining device is used to form a copying flow passage for machining a titanium alloy artificial joint prosthesis with the titanium alloy artificial joint prosthesis, the rapid flow of a solid-liquid two-phase abrasive particle flow in the copying flow passage is used for forming full turbulence, and abrasive particles in the solid-liquid two-phase abrasive particle flow are used for performing unordered micro force and micro cutting on the titanium alloy artificial joint prosthesis; in the machining process, high-pressure gas is intermittently introduced into the copying flow passage and impacts the abrasive particles to distribute towards workpieces so as to improve the probability of collision of the abrasive particles to the surface of the titanium alloy artificial joint prosthesis and prevent the abrasive particles from submerging into the bottom of the copying flow passage. The titanium alloy artificial joint surface turbulence precision machining device is simple in structure and easy in design; a copying end cover forms good copying with the surface of the titanium alloy artificial joint prosthesis; the soft abrasive particle flow can be in good contact with the surface of the titanium alloy artificial joint prosthesis, so that the machining precision of a titanium alloy artificial joint is higher, and the processing effect is more uniform.

technical field [0001] The invention relates to the technical field of artificial joint processing, and is especially suitable for processing titanium alloy artificial joints with complex heterosexual curved surfaces. More specifically, it relates to a turbulent precision machining method and device for titanium alloy artificial joint curved surfaces. 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...
