Abstract

With a rotary polishing apparatus for blade confining part, comprise casing, cover body; Casing center is provided with whirligig, workpiece installed by whirligig, cover body is sleeved on above casing, cover body can rotate about the axis, the polishing room of sealing is formed between mask body intracavity and cabinets cavity, uniform blade on cover body inner surface, casing both sides are respectively equipped with abrasive Flow entrance port and abrasive Flow exit portal, and abrasive Flow entrance port and abrasive Flow exit portal communicate with polishing room.Abrasive Flow runner is formed in polishing room in the present invention, in casing, whirligig can drive workpiece to rotate, uniform blade on cover body inner surface and cover body can rotate under the drive of motor, workpiece is contrary with cover body direction of rotation, thus make the lapping liquid in polishing room produce relative disordered motion to realize micro-power micro cutting on surface, reach minute surface level surface roughness, polishing effect is good, precision is high.

Description

With the rotary polishing apparatus of blade confining part
Technical field
The present invention relates to the abrasive Flow polishing processing device in abrasive Flow polishing field, particularly a kind of titanium alloy artificial joint.
Background technology
Joint prosthesis is medically extensively utilized as a kind of implant devices with function of joint, the metal parts of early stage joint prosthesis adopts stainless steel to make, along with the progress of technology, cobalt-alloy material is applied because it has better corrosion resistance, wearability and mechanical performance, develop again titanium or titanium alloy material in recent years, titanium-containing materials not only corrosion-resistant, intensity good, and proportion is little, easier and that people is autologous bone grows together, having good biocompatibility, is desirable artificial joint material.
The polishing degree on joint prosthesis surface has vital impact to its function and service life, therefore, titanium alloy artificial joint prosthese after overmolding can not be directly applied for inside of human body, also need through subsequent technique process such as a series of grinding and buffings, the surface of final acquisition high accuracy and best bright finish, forms the joint prosthesis with human body bone no-float.
Thermal conductivity and the cutting ability of titanium alloy are poor, and 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, advantage is embodied, particle impacting material surface is utilized exactly as ground liquid jet grinding-polishing titanium alloy, at material surface generation energy redistribution, under the impact of particle, be initially at material surface produce elasticity or plastic deformation, and then material not plane surface crest place produce high pressure stress, make microcosmic injustice place material produce shear displacemant, Plastic Flow and material to run off, thus material surface unevenness is reduced gradually, finally reach the object of grinding-polishing test specimen.But joint prosthesis surface is the complex-curved of different curvature, is easily obstructed when abrasive Flow flows through the catastrophe point place of joint prosthesis surface flex point and singular point, makes polishing uneven, be difficult to reach desirable polishing effect, on the other hand, abrasive Flow pressure at inlet is high, speed fast, and polishing intensity is high, and near the place of outlet, speed and pressure all reduce, and make polishing uneven, and the processing of abrasive Flow single direction, workpiece can be made to produce striped, have impact on quality of finish and precision greatly.
Summary of the invention
For a difficult problem for the complex-curved skin processing of titanium alloy artificial joint, the invention provides the rotary polishing apparatus with blade confining part that a kind of polishing performance is good, precision is high.
The technical solution adopted for the present invention to solve the technical problems is:
With the rotary polishing apparatus of blade confining part, comprise casing, cover body; Described casing center is provided with whirligig, and workpiece installed by described whirligig, and described cover body is sleeved on above casing, and described cover body can rotate about the axis, and forms the polishing room of sealing between described mask body intracavity and cabinets cavity, uniform blade on described cover body inner surface.
Described casing both sides are respectively equipped with abrasive Flow entrance port and abrasive Flow exit portal, and described abrasive Flow entrance port and abrasive Flow exit portal communicate with polishing room.
Further, described cover body inner surface is semicircle sphere, and described blade is welded on cover body inner surface, and described blade lean is installed, and connects motor above described cover body by rotating shaft.
Further, described whirligig comprises turntable, connecting axle, motor, and described turntable is arranged in casing, and described motor is arranged on outside casing, and described motor connects turntable by connecting axle, and workpiece installed by described turntable.
Mentality of designing of the present invention and advantage show: the polishing room 1, forming sealing between casing and cover body, and casing is provided with abrasive Flow entrance port and exit portal, therefore can form abrasive Flow runner in polishing room.2, trade union college is in casing, is provided with whirligig in casing, and workpiece can be driven to rotate, and improves the efficiency of polishing on the one hand, and situation abrasive Flow can being avoided to be subject to resistance in curved surface flex point or singular point place and to cause polishing uneven on the other hand, polishing effect is good.3, on cover body inner surface, uniform blade and cover body can rotate under the drive of motor, lapping liquid rotates under the effect of blade, and workpiece is contrary with cover body direction of rotation, workpiece is counter-rotation in lapping liquid, thus make the lapping liquid in polishing room produce relative disordered motion to realize micro-power micro cutting on surface, reach minute surface level surface roughness, polishing precision is high.
