Abstract
The invention relates to center-holed infrared lens processing technology, which comprises the following steps of: processing the external diameter of a blank milling sheet of a lens, wherein the external diameter dimension is 1-2mm greater than the needed external diameter dimension; placing the lens into a fixture, and performing central hole punching by using a diamond bit on a precision drilling machine; performing inner bore milling, making the milled inner bore of the lens reach the designed precision, stringing the holed lenses by using inner bore zinc bars with the same specification through an optical centering edging machine, and fixing the holed lenses by using an optical cement; grinding excircles to reach the precision of the excircles of the lenses; and finally, performing posttreatment and cleaning. The center-holed infrared lens processing technology effectively guarantees the concentricity of the excircle and the inner bore of the infrared lens, obviously reduces the error, guarantees the production repeatability of the product, obviously improves the rate of finished products, and reduces the production cost.
Description
Technical field
The present invention relates to the Infrared Lens of a kind of infrared optics instrument, especially a kind of Infrared Lens processing technology of central punch with central punch.
Background technology
Infrared Lens such as germanium, silicon etc. are because the special requirement on the light path, and some need have a through hole at the center of lens, satisfying the optical design requirement, this just need we add man-hour will be in the central punch of lens.Conventional machining process in the past is after the lens shape dimensioned is finished, and then finishes this operation of punching.The greatest problem that this way is brought is exactly: can't guarantee the concentricity in eyeglass and hole, error is bigger than normal, and has randomness, makes repeatability to guarantee, the work in-process rejection rate is also higher.
Summary of the invention
In order to overcome above defective, the technical problem to be solved in the present invention is: propose a kind of yield rate height, concentricity height, the Infrared Lens processing technology of the central punch that error is little.
The technical solution adopted in the present invention is: a kind of Infrared Lens technology of central punch, at first the blank milling sheet external diameter of eyeglass is processed, outside dimension is slightly larger than required outside dimension 1～2mm, and then eyeglass placed frock clamp, on precision drilling machine, carry out the center pit perforation processing with diamond head, then carry out the endoporus milling again, the eyeglass endoporus reaches design accuracy after the milling, by the endoporus zinc bar of optics centring edging machine the punching eyeglass is stringed together with same size, fix with the optical cement eyeglass that will punch, carry out the grinding cylindrical then, reach the lens edge precision, carry out lower wall at last and handle, clean.
According to another preferred embodiment, further comprise
According to another preferred embodiment, the Infrared Lens processing technology of central punch comprises that further the Infrared Lens technical indicator of central punch is as follows, cylindrical tolerance+0.01, endoporus precision ± 0.01.
The invention has the beneficial effects as follows: the present invention has effectively guaranteed the concentricity of Infrared Lens cylindrical and endoporus, significantly reduces error, and the production repeatability of product is guaranteed that yield rate obviously improves, and has reduced production cost.
Embodiment
The present invention is further detailed explanation with preferred embodiment in conjunction with the accompanying drawings now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of Infrared Lens technology of central punch, a kind of Infrared Lens technology of central punch, at first the blank milling sheet external diameter of eyeglass is processed, outside dimension is slightly larger than required outside dimension 1～2mm, and then eyeglass placed frock clamp, on precision drilling machine, carry out the center pit perforation processing with diamond head, then carry out the endoporus milling again, the eyeglass endoporus reaches design accuracy after the milling, the punching eyeglass is stringed together with the endoporus zinc bar of same size by optics centring edging machine, fixes with the optical cement eyeglass that will punch, carry out the grinding cylindrical then, reach the lens edge precision, carry out lower wall at last and handle, clean.Infrared Lens technical indicator after the processing is as follows: cylindrical tolerance+0.01, endoporus precision ± 0.01.Thereby for various infrared gears provide high-precision punching lens.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
