Description
Technical field
The present invention relates to abrasive Flow polishing field, particularly a kind of titanium alloy artificial joint turbulent flow precise processing device.
Background technology
Joint prosthesis is medically extensively being utilized as a kind of implant devices with function of joint, the metal parts of early stage joint prosthesis adopts stainless steel to make, progress along with technology, cobalt alloy material is applied because it has better corrosion resistance, wearability and mechanical performance, developed again in recent years titanium or titanium alloy material, titanium-containing materials not only corrosion-resistant, intensity good, and proportion is little, bone easier and that people is autologous grows together, having good biocompatibility, is desirable artificial joint material.
The polishing degree on joint prosthesis surface is on its function and have vital impact service life, therefore, titanium alloy artificial joint prosthese after overmolding can not be directly applied for inside of human body, also need to process through subsequent techniques such as a series of grinding and buffings, the final surface that obtains high accuracy and best bright finish, forms the joint prosthesis with human body bone no-float.
Joint prosthesis surface is the complex-curved of different curvature, and the thermal conductivity of titanium alloy and cutting ability poor, in existing surface accurate process technology, most of method is difficult to be suitable for.Because abrasive Flow can form good profiling contact, therefore in curved surface and Special-Shaped Surface processing, embody advantage, existing abrasive Flow has formed some method of surface finish, as extrusion honing, abrasive particle water jet polishing etc., these class methods need to apply powerful extruding force or spray power abrasive Flow, make surface of the work be subject to powerful scraping or the impact of abrasive particle, though working (machining) efficiency is high, but under abrasive particle forceful action, can not obtain good surface roughness, and can leave the cutter trade with obvious directionality on surface, therefore, they can only be as surperficial rough polishing processing.Number of patent application is that 201110041218.8 " titanium alloy artificial joint curved surface turbulent flow Precision Machining new method and special purpose device thereof " provides a kind of local precision machined new method of constraint formula titanium alloy artificial joint turbulent flow that covers, by the prosthese shape with to be processed consistent join mould, at artificial joint prosthesis outer surface with join in the runner of mould inner surface and form turbulent flow, utilize the frequent effect of micro-power micro cutting of abrasive particle to realize the progressively polishing on surface, although the method can realize better processing effect, but the viscosity due to abrasive Flow, temperature, flow velocitys etc. all produce impact greatly to polishing effect, machining accuracy is difficult to obtain desirable control, polishing effect is single.
Summary of the invention
A difficult problem for the complex-curved polishing processing of titanium alloy artificial joint, the invention provides the temperature control abrasive Flow curved surface turbulent flow burnishing device that a kind of polishing precision is controlled, polishing performance good, precision is high.
The technical solution adopted for the present invention to solve the technical problems is:
Temperature control abrasive Flow curved surface turbulent flow burnishing device, comprise confining part, temperature control abrasive Flow EGR, described confining part is sleeved on outside joint prosthesis, between described confining part inner surface and joint prosthesis outer surface, form the profiling runner of even thickness, on described confining part, be at least provided with one group of profiling runner exit and profiling runner entrance.
Described temperature control abrasive Flow EGR comprises storage mixer, pump, heater, tube connector, described pump connects respectively mixer and profiling runner entrance by tube connector, between described pump and profiling runner entrance, be provided with heater, described storage mixer is communicated with profiling runner exit by tube connector.
Further, described pump is membrane pump, and described tube connector is insulating tube.
Further, described storage mixer is that temperature control stores mixer.
In the present invention, lapping liquid stores in mixer and evenly mixes in temperature control, mixed lapping liquid enters profiling runner under the effect of pump, before entrance, by heater, carry out temperature control and carry out again polishing, lapping liquid after polishing completes flows out from profiling runner exit, by tube connector, be recovered to temperature control and store in mixer, form Circulated polishing.
Mentality of designing of the present invention and advantage show: 1, the viscosity of lapping liquid size can affect polishing effect, strong resistance while flowing through deep camber complex surface as strong viscosity abrasive Flow can destroy joint prosthesis configuration of surface, and the lapping liquid of turbulent flow polishing is the fluid that meets Newton's formula, its viscosity is only relevant with temperature, in the present invention, by temperature control abrasive Flow EGR, can accurately control the temperature of lapping liquid, thereby the viscosity of adjusting lapping liquid is controlled throwing light intensity, can improve the efficiency of surface finish, optimize polishing effect.2, by the profiling of joint prosthesis curved surface, set up local covering surface confining part, build the controlled profiling runner of abrasive Flow, processed curved surface becomes a part for runner wall, abrasive Flow can form good contact with the joint prosthesis surface of complicated shape, make lapping liquid enter the abundant state of development of turbulent flow, micro-power micro cutting of realizing surface by the disordered motion of abrasive particle, reaches minute surface level surface roughness, and polishing precision is high.3, temperature control abrasive Flow mixer can be controlled being stored in the temperature of the abrasive Flow in mixer, abrasive Flow is cooled to a quite low temperature, abrasive Flow arrives heater through membrane pump, insulating tube like this, can be so that the temperature of abrasive Flow forms a gradient and circulation, thereby can reach the object of controlling abrasive Flow viscosity, further reach the control to polishing effect.4, by pump, can control the flow velocity of lapping liquid, realize the Effective Regulation to turbulence state, polishing performance is good.5, lapping liquid can be recycled, and reduces sewage discharge and realizes clean processing, and save the energy.
