Abstract

The utility model relates to the field of polishing of abrasive particle flow, and in particular relates to an abrasive particle flow polishing device for titanium alloy artificial joints. The device comprises a box body, a cover body and a blade wheel, wherein a rotating device is arranged in the center of the box body; a workpiece is arranged on the rotating device; the cover body covers the upper part of the box body; a sealing polishing chamber is formed between the cover body and the inner cavity of the box body; an abrasive particle flow injection port and an abrasive particle flow ejection port are respectively formed in the two sides of the box body and are communicated with a polishing chamber; the blade wheel is arranged in the polishing chamber and positioned above the workpiece and can rotate around a rotating shaft. According to the abrasive particle flow polishing device, an abrasive particle flow channel is formed in the polishing chamber, and the rotating device in the box body can drive the workpiece to rotate; the blade wheel is arranged above the polishing chamber and can be driven by the motor to rotate, and the rotation direction is opposite to that of the workpiece, so that micro-power micro-cutting of the surface is realized by means of relative disordered motion produced by a grinding liquid in a polishing chamber, and the mirror face level surface roughness, high polishing effect and high accuracy are realized.

Description

A kind of abrasive Flow polishing processing device with blade wheel
Technical field
The utility model 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 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.
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, embody advantage, as grind liquid jet grinding-polishing titanium alloy and utilize exactly particle impacting material surface, at material surface generation energy redistribution, under the impact of particle, be initially at material surface and produce elasticity or plastic deformation, and then do not produce high pressure stress in the crest place of plane surface at material, the uneven place of microcosmic material production shear displacemant, Plastic Flow and material are run off, thereby 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, when flowing through the catastrophe point place of joint prosthesis surface flex point and singular point, abrasive Flow is easily obstructed, and make polishing inhomogeneous, be difficult to the polishing effect that reaches desirable, on the other hand, abrasive Flow porch pressure is high, speed is fast, and polishing intensity is high, and near the place exporting, speed and pressure all reduce, and make polishing inhomogeneous, and the processing of abrasive Flow single direction, can make workpiece produce striped, affect greatly quality of finish and precision.
Utility model content
For a difficult problem for the complex-curved polishing processing of titanium alloy artificial joint, the utility model provides the abrasive Flow polishing processing device with blade wheel that a kind of polishing performance is good, precision is high.
The utility model solves the technical scheme that its technical problem adopts:
An abrasive Flow polishing processing device with blade wheel, comprises casing, cover body and blade wheel; Described casing center is provided with whirligig, on described whirligig, workpiece is installed, described cover body is sleeved on casing top, between described cover body and cabinets cavity, form the polishing room of sealing, 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.
Described blade wheel is arranged in polishing room and is positioned at the top of workpiece.
Further, described cover body is hemisphere cover body, and the rotating shaft of described blade wheel connects motor through after hemisphere cover body.
Further, described whirligig comprises turntable, connecting axle, motor.Described turntable is arranged in casing, and described motor is arranged on outside casing, and the motor of telling connects turntable by connecting axle, on described turntable, workpiece is installed.
Mentality of designing of the present utility model and advantage show: 1, between casing and cover body, form the polishing room of sealing, casing is provided with abrasive Flow entrance port and exit portal, so form abrasive Flow runner in Ke polishing room.2, workpiece is arranged in casing, in casing, be provided with whirligig, can drive workpiece rotation, improved on the one hand the efficiency of polishing, can avoid on the other hand abrasive Flow to be subject to resistance and to cause the inhomogeneous situation of polishing in curved surface flex point or singular point place, avoid the processing of abrasive Flow single direction, can make workpiece produce striped, polishing effect is good.3, polishing room top is provided with blade wheel, blade wheel can be under the drive of motor rotation and direction of rotation contrary with workpiece direction of rotation, make the lapping liquid in polishing room produce micro-power micro cutting that relative disordered motion is realized surface, reach minute surface level surface roughness, polishing precision is high.
