Description
Technical field
The present invention relates to a kind of magnetic jet polishing tool head, relate in particular to device, belong to ultraprecise optical surface manufacture field the jet polishing of optical element compound motion attitude magnetic jet body.
Background technology
Along with the continuous development of science and technology, people are more and more harsher to the requirement of the shape of optical element and quality, and this has also promoted the flourish of various polishing technologies.At present, advanced manufacturing technology mainly contains: small tool head numerical control polishing technology, Technique of Magnetorheological Finishing, abrasive water-jet polishing technology etc.Small tool head numerical control polishing technology in the grinding and polishing process because the wearing and tearing and the distortion of mill, be difficult to guarantee the stable operating characteristic of mill, thereby reduced polishing error convergence efficient, moreover, because the restriction of the size of mill makes to be difficult to the bigger face type of curvature is accurately processed.Technique of Magnetorheological Finishing is a kind of flexible polishing technology, polishing pad does not have wearing and tearing in polishing process, therefore can realize stable Super-smooth Surface Polishing, but owing to need field generator for magnetic, so be difficult to realize smart littleization of polishing tool structure, thereby be difficult to realize polishing to big gradient concave surface.The abrasive water-jet polishing technology is to be ejected into surface of the work by the liquid that will have abrasive material, the surface is produced shear action, realize a flexible polishing technology of polishing, in the polishing, rubbing head does not have wearing and tearing, and polishing spot area is less, therefore can realize accurate super-smooth surface processing, but because fluid column just gets muddled after through very short distance, thereby be difficult to realize, promptly be difficult to realize accurate polishing high steepness concave surface face type to longer-distance accurate polishing.
Magnetic fluidics is by abrasive water-jet and magnetic converting technique development, the jet beam of low viscosity magnetorheological liquid that mainly makes compound abrasive is by behind the localized axial magnetic field, magnetic rheology effect takes place increases the stability on jet beam surface, forms convergence, conformality and the good hardenable fluidic bundle of collimation and is ejected into the correction that surface of the work is realized residual error.Therefore not only can realize the processing of ultraphotic sliding surface type, and lossless for nozzle in process, the most important thing is that it can realize remote accurately processing, processing high gradient concave surface is had remarkable advantages.
Have two kinds of magnetic fluid jet nozzles comparatively general at present: a kind of structure of magnetic fluid jet nozzle is at base with nozzle and coil stationary, make and to produce vertically to magnetic field by coil from the liquid of the vertical direction of shower nozzle ejection, directly impact workpiece, workpiece is produced removal, cater to the fluid column of injection again by rotation and swing workpiece; Another kind is similar with first kind, but makes shower nozzle with respect to the injection center certain offset be arranged when spraying, and rotates around pivot by the driven by motor shower nozzle again.These two kinds of finishing methods can be realized three kinds of spray patterns: first kind of form is that vertical incidence is sprayed, and the axis of a cylinder heart and the institute processing stand place workpiece face normal that promptly spray fluid column overlap, and it is removed function and is down " W " shape; Second kind of form is that simple oblique incidence is sprayed, and promptly sprays fluid column with processing stand place workpiece face normal is angled, but fluid column can not be around workpiece face normal rotation herein, thus its remove function present in the middle of the big edge of removal remove little irregular distribution; The third form is the rotary-jet that offset is arranged, and it removes function is simple revolution symmetry classes gaussian shape.For the shower nozzle of first kind of shape, it can realize preceding two kinds of spray regimes, but is difficult to realize being the polishing of the removal function that turns round symmetrical class gaussian shape distribution, the efficient of feasible polishing and precision reduction; Shower nozzle for second kind of shape, it can obtain the function that removes that first kind of form shower nozzle can obtain, and the class Gauss that can obtain to turn round symmetry removes function, but for obtaining the removal function of revolution symmetry, requiring its spray regime is that vertical incidence is sprayed, and because its control offset can not be removed functional style thereby retrained the obtainable class Gauss's shape of institute greater than the radius that sprays fluid column.The invention enables the variation of magnetic jet jet polishing mode, can realize the polishing of polytype removal function, and then realize the high-efficiency and precision polishing.
