Description
Technical field
This utility model relates to the processing of optical element, and particularly a kind of honeycomb fashion can heavily join aspheric surface correction polishing disk.
Background technology
The polishing of aspheric surface part produces, and is the new direction of contemporary optics part production, and aspheric surface is better than many optical properties of tradition coquille with it, leads the developing direction of optical instrument, equipment, device and product.A piece of aspherical mirror can substitute multi-disc spherical lens, makes product more advanced, high-quality, in high precision, and the feature of high profit.
The production links such as aspheric production belongs to optical effect correction category, generally has blanking, molding, corase grind, fine grinding, polishes, plated film.Wherein polishing link is the key link of non-spherical lens, and in this link, the polishing mode of aspherical lens and spherical lens and the equipment of use have very big diversity.The polissoir of coquille is highly developed.Using swing type single shaft, 2 axles, 4 axle buffing machines, equipment price is cheap.During polishing, workpiece carries out rotation on Work piece rotary disc, and the polishing lacquer disk(-sc) with spherical shape swings at workpiece surface, and constantly adds polishing fluid, to complete the polishing of spherical lens.
But aspheric surface polishing equipment can not be the simple modifications of spherical polishing equipment, owing to the radius of curvature on its surface of aspherical lens is different everywhere, curvature unlike spherical lens surface is equal everywhere, so its polishing disk cannot be polished with the polishing disk with a kind of fixing curvature, so just cannot be carried out the polishing of whole dish swing type.
The aspheric polishing machine of main flow in the world, it it is the numerical control polishing under computer controls, its rubbing head is that than workpiece, big slight many rubbing heads carry out in employing, under control of the computer, little rubbing head moves to a certain polishing position of workpiece, according to the face shape error of aspherical lens on this position and amount of curvature, determine the little rubbing head of the high speed rotating time of staying on this position and lateral attitude, to reach the purpose that material is removed.This kind of equipment has the Bonnet Too l Polishing machine of Britain, magnetorheological polishing machine of the U.S. etc. in the world.Such apparatus processing part bore is big, and efficiency is high, and precision is good, is the developing direction that optical element advanced person manufactures in the world at present.But such equipment cost price height is to millions of between 10,000,000 yuan, and most of producers make can not afford.
The aspheric surface polishing of most domestic producer produces and adopts the method that artificial polishing produces.Namely on the basis of workpiece rotation, hand-held polishing disk, it is modified polishing by rule of thumb.This rubbing head is also referred to as polishing disk, generally little many than workpiece size.Polisher's face shape error situation according to aspherical mirror, the shape of the polishing material on timely modification polishing disk, to reach the purpose of the surface emphasis polishing to aspherical lens specific region.Generally this kind of polishing disk is a spherical polishing dish, and polishing material is affixed to one layer of Colophonium on its sphere or polyurethane skin.Polishing pad shape on this kind of polishing disk is relatively fixed, and polished aspheric shape is ever-changing, correction due to the not part of coplanar shape, the shape and the size that need the polishing pad of correspondence change polishing disk carry out corresponding correction polishing, so in actual production process, for avoiding revising continually polishing disk, it is necessary to prepare the polishing disk of many different polishing pad shapes, bother very much.
Utility model content
The purpose of this utility model is in that to provide a kind of honeycomb fashion can heavily join aspheric surface correction polishing disk, according to the face shape error situation of aspheric surface optical accessory, the movable polishing pad on polishing disk can carry out layout combination flexibly, reach to revise the effect of face shape error.
For solving above-mentioned technical problem, this utility model includes: cast iron polished die and movable polishing pad, wherein: cast iron polished die has some step through-holes, each step through-hole is perpendicular to the normal direction of the burnishing surface of cast iron polished die, each step through-hole is cellular distribution, step through-hole includes: the polishing pad unloading port being connected and polishing pad installing hole, wherein: the diameter of polishing pad installing hole, more than polishing pad unloading port, arranges movable polishing pad in polishing pad installing hole.
Described movable polishing pad includes: the circular magnet base being mutually bonded and polyurethane polishing pad, and circular magnet base attracts mutually with cast iron polished die.
The burnishing surface shape of described cast iron polished die is consistent with the burnishing surface shape of polished workpiece, and the face shape error of this burnishing surface is less than or equal to 100 microns.
The diameter of described cast iron polished die is more than the diameter 2mm of polished workpiece.
This this utility model layout activity polishing pad efficiently solves the aspheric surface optical accessory problem at the manual polishing tool dish repaiied in parabolic process, this kind of polishing disk can according to the face shape error situation of aspheric surface optical accessory, polishing pad on polishing disk is carried out layout combination flexibly, reach to revise the effect of face shape error, solve the changeless shortcoming of polishing pad on the correction polishing disk of routine, improve efficiency and reusability that instrument uses, improve the manual work efficiency repairing throwing.The shape of this utility model polishing disk heavily can be joined according to tool-face shape scene easily；When heavily joining polishing disk, do not heat, do not discard, the movable repeatable utilization of polishing pad；Only use one and can heavily join polishing disk, it is possible to meet needs overall, local polishing；This polishing disk has highly versatile, and movable polishing pad shape arbitrarily sets, the features such as reusability is good, easy to use.
