Description
Technical field
This utility model relates to Ultra-precision Turning, particularly relate to a kind of for cluster micropore inner surface be polished from supercharging high speed abrasive Flow burnishing device.
Background technology
Along with modern science and technology progress, the application in the industries such as space flight, aviation, automobile, weapon, electrical equipment, chemical industry, hydraulic pressure, medical treatment of the various special holes is more and more extensive, such as group's micropore etc. on the screwed hole in the rifling hole of gun barrel, precision machine tool, automotive fuel nozzle, circuit board, wherein the rifling hole required precision deflection of gun barrel reaches more than 0.2 μm less than 1 μm and inside surface roughness, the most tens thousand of of the number cells of group's micropore on circuit board, aperture is less than 50 μm.More and more stricter to machining accuracy and the surface quality requirements of these special holes, after utilizing conventional technique to process this kind of special hole, inner surface accuracy is the most not ideal enough, it is difficult to meet the prescription of the precise treatment that product improves day by day, need further polishing could meet it and use requirement, thus need badly can efficiently, high accuracy these special hole inner surfacies are carried out Ultraprecise polished technology.
The method being currently employed for hole machined mainly has: machine drilling, laser boring, spark machined etc..But, by the method for machine drilling, burr, this burr can be stayed to affect using effect in the exit in hole；All can leave recast layer at hole wall by laser and spark machined, thus affect the service life in hole, make the surface quality in hole deteriorate, it is therefore desirable to the inner surface of this pores is polished.And at present finishing method to special hole mainly has tradition polishing, ion beam polishing, air bag polishing, abradant jet polishing etc..Tradition polishing the most manually uses flexible brush that endoporus carries out the polishing of wiping back and forth, and not only labor intensity is big, efficiency is low, the health of infringement workman, and cannot be applicable to elongated hole and micropore etc..Ion beam polishing etc. can obtain high surface roughness, but material removing rate is extremely low, after being generally used only for the glossings such as CMP, reduces workpiece surface damage layer further, improves surface quality, and processing cost is high.Air bag polishing clearance is limited, and finishing method and device are complicated, mainly apply to the polishing of aspherical optical element.But the defect of these methods maximums is to be not suitable for the processing of elongated hole and minute aperture, the polishing of the most elongated threaded hole is the most helpless, this is closely to be polished owing to these finishing methods need that polishing tool is deep into internal surface of hole, the size restriction requirements polishing tool of elongated hole must be the most elongated, and the polishing tool of these finishing methods can not accomplish this point due to technological requirement, which limits the application that these finishing methods polish in elongated hole and minute aperture inner surface.
The advantage of conventional abrasive jet polishing technology (such as water jet polishing, gas Jet Polishing) is a lot, application prospect is preferable, it mainly by being acted on surface of the work by the polishing fluid being mixed with tiny abrasive particle of nozzle orifice ejection at a high speed, reaches grinding by the high velocity impact shear action of abrasive particle and removes the Jet Polishing principle of material.Owing to can dissipate rapidly after in these Jet Polishing technology, micro-abrasive jet leaves nozzle, the processing bundle of collimation can not be formed, so that nozzle close contact surface of the work carries out micro-polishing, less additionally, due to jet size, in micro-abradant jet course of processing, easily block, cause Jet Polishing inefficient.What is more important, current water jet or gas fluidics are all to use single injector mode to be polished processing, elaboration point is little, and working (machining) efficiency is relatively low, and, owing to using single injector closely to polish, if endoporus to be processed, needing to stretch in endoporus by nozzle, this just requires that endoporus aperture wants to accommodate putting into of nozzle, limit the endoporus aperture to be polished, also cannot polish smoothly for the non-rectilinear groove (such as helicla flute, rifling etc.) in endoporus.
Abrasive flow machining (Abrasive Flow Machining, it is called for short " AFM ") it is also referred to as extrusion honing at home, its principle is to extrude half solid fraction abrasive particle under squeezing honing machine effect to rub processed piece surface, thus is polished piece surface.But abrasive flows polishing technology is applied the most very well, owing to semi-solid phase abrasive Flow is that abrasive particle realizes relative to the compressional movement of surface to be machined, Kong Yue little then glossing is more difficult to, required extruding force is the biggest, thus abrasive Flow technique cannot polish the aperture micropore less than 50 microns, cluster micropore, elongated hole at present；On the other hand, current abrasive Flow burnishing device extrudes semi-solid phase abrasive Flow sluggish flow in workpiece duct mainly by squeezing honing machine, then abrasive Flow pressure is little, flow velocity is slow, working (machining) efficiency is low, and the abrasive particle of slow flow can scratch surface of the work simultaneously affects machining accuracy.Therefore, abrasive Flow how high pressure, to inject workpiece duct at a high speed be the difficult problem needing to solve.Furthermore existing abrasive Flow finishing method and device can not take into account the irregular hole of major diameter, elongated hole and the polishing of group's micropore, and abrasive Flow burnishing device structure is complicated, operation difficulty, and cost is high.
