Abstract
The utility model provides a flexible polisher of non-spherical optical component, comprising a support member and a joint arranged on the machine spindle at the lower end of the support member. The support member can be connected with the pendulum shaft of the machine through a universal bearing. The inner of the support member is a hollow cavity structure. The lower end of the support member is fixed with a flexible polished die. The support member and the flexible polished die form a compressing gas cell together. The support member is opened with a gas inlet of compressed gas. Because the support member is opened with a gas inlet of compressed gas, the surface of the flexible polishing material engenders deformation through the compressed gas. The goal of the polished die contacting the polished part closely in large area can be obtained. The uniform flexible (not alter the original surface shape)polishing of the surface of the non-spherical optical component can be achieved through the regulation of the swing amplitude, the angle and the gas pressure of the support member.
Description
Technical field
The utility model relates to a kind of optical element processing and ultra-precision processing apparatus, particularly a kind of aspheric surface optical accessory flexible polishing device.
Background technology
Aspheric surface optical accessory is a kind of very important optical element, as paraboloidal mirror commonly used, hyperbolic mirror, ellipsoidal mirror etc.Aspheric surface optical accessory can obtain the unrivaled good image quality of spherical optics part, in optical system, can be good at correcting multiple aberration, improve image quality, raising system distinguishing ability, it can replace a plurality of spherical parts with one or several aspheric surface part, thereby the simplification apparatus structure reduces cost and effectively alleviates instruments weight.Though aspheric surface optical accessory has many benefits, do not find a kind of high precision, low cost so far yet and be applicable to the aspheric surface part processing method of multiple production form.Therefore, relevant aspheric surface processing technology is the pressing issues that need research and solve for a long time.The polishing technology that is adopted in the aspheric surface optical accessory process has determined the precision and the optical property of optical element, seeks the aspheric surface optical accessory polishing technology of high efficiency, low cost, is long term research of scientific worker.The finishing method that is used for aspheric surface optical accessory at present has: computer control small tool polishing (CCOS), computer control strain disc polishing (CCSL), stress polishing (SP), the polishing of film band (Membranes) instrument, ion beam polishing and magnetorheological polishing, hydration polishing, shallow cryogenic polishing etc.CCOS is moved on surface to be machined by the computer control polished die more much smaller than workpiece; The polishing disk that the strain disc polishing is adopted constantly produces real-time deformation in polishing process, adaptive surface to be machined is finished processing; The stress polishing is provided with supporting to workpiece by designing requirement, and stress application makes it distortion, processes by smooth sphere or plane, discharges stress after finishing again, thereby produces required aspheric surface; Film band instrument polishing technology adopts enough thin film band, applies the polish pressure of needs by the computer control driver at the back side; The hydration polishing method is not used abrasive material and chemical corrosion liquid, use does not produce the material of solid phase reaction and makes abrasive disk between abrasive disk and workpiece, device can be with traditional grinding and burnishing device, but must under water or water vapor atmosphere, process, removal be the hydrate layer that on material surface, generates; Shallow cryogenic polishing method is chilled in polishing fluid on the polishing disk exactly, forms the polishing mould layer of an ice, can obtain same shape polishing mould layer accurately, when ice mould layer and workpiece contact and do relative motion, just produces polishing effect.Different with above-mentioned six kinds of contact machining process is, ion beam polishing then is that the non-contacting physical removal methods of employing is the bombardment of ion beam to the surface, and magnetorheological polishing then is that a kind of jet that the Magnetorheologicai polishing liquid that is dissolved with polishing material produces under the high voltage magnetic field effect is removed the material on surface.The application background kind that above method is had nothing in common with each other, the low part of suitable aspherical degree that has is such as the ion polishing method; What have then is that equipment is complicated and valuable especially, as strain disc polishing, magnetorheological polishing; The part that the only suitable processing bore that also has is little etc.The surface of the aspheric surface optical accessory of above prepared in various methods all can not be polished uniformly in addition.
Summary of the invention
The utility model purpose is to provide the uniform aspheric surface optical accessory flexible polishing of surface finish device in a kind of aspheric surface optical accessory process, and its great advantage is not change original shape, and is uniform polish.
For achieving the above object, the technical solution adopted in the utility model is: comprise rubbing head and joint, wherein rubbing head is by support member, compression air chamber, fixture and flexible polishing mould are formed, have the Compressed Gas air inlet on the rubbing head, contacted at support member lower end and polished die is polished part, it is installed on the joint, be characterized in, support member can be connected with the machine balance staff by universal bearing, support member inside is a cavity structure, be fixed with the flexible polishing mould in the lower end of support member, support member and flexible polishing mould have been formed compression air chamber jointly, also offer the Compressed Gas air inlet on the support member.
Another characteristics of the present utility model are: the flexible polishing mould is fixed on the support member by fixture; Rubbing head is to be connected by universal bearing with balance staff; The flexible polishing mould is made of single or multiple lift flexible polishing material; The Compressed Gas air inlet has at least more than two; The lower end of joint also is provided with water fender.
Because the utility model offers the Compressed Gas air inlet on support member, make the flexible polishing material surface produce distortion by Compressed Gas, to reach the purpose that polished die contacts with the close large tracts of land of polished part.By regulating the amplitude of oscillation, angle and the gas pressure of support member, reach the even flexible polishing on aspheric surface optical accessory surface.
Description of drawings
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Accompanying drawing is an overall structure schematic diagram of the present utility model.
The specific embodiment
Referring to accompanying drawing, the utility model comprises rubbing head 12 and the joint 8 that links to each other with main shaft 11.Rubbing head is made up of support member 1, compression air chamber 3, fixture 4 and flexible polishing mould 5.The lower end of joint 8 is provided with water fender 10, support member 1 can be connected with machine balance staff 9 by universal bearing 7, offer the Compressed Gas air inlet 2 more than three on the support member 1, tighten up by fixture 4 at support member 1 and single or multiple lift flexible polishing mould, support member 1 has been formed compression air chamber 3 jointly with the flexible polishing mould.
At first the utility model is installed on the ordinary optical burnishing machine in use, when work, in compression air chamber 3, send into compressed and multiplexed gas by Compressed Gas air inlet 2, the big I of pressure of every road Compressed Gas is regulated respectively by control assembly, but the pressure of compression air chamber 3 forces flexible polishing mould 5 that deformation take place and closely contacts with uniform pressure in the large tracts of land scope with processed optical element 6 on being installed in joint 8, by balance staff 9 and universal bearing 7 control movement locus of the present utility model and pressure sizes, reach the purpose on uniform polish aspheric surface optical accessory surface.
