Abstract
The invention discloses an objective lens assembly process. A flat pushing objective lens type rotating objective lens focusing device consists of a focusing hand wheel, a rubber sleeve, a press ring, a casing, a sealing ring, a position limiting screw and an objective lens group, wherein the objective lens group is fixed by a pressing ring and an isolation ring, the focusing hand wheel is reliably connected with the casing through the press ring, the rubber sleeve is covered on the focusing hand wheel, the objective lens group is respectively screwed into the focusing hand wheel and the casing through the sealing ring, and the position limiting screw is positioned at the tail end of the focusing hand wheel and is respectively connected with the focusing hand wheel and the objective lens group. The objective lens assembly process has the characteristics that the structure is simple, the process performance is good, the sealing is easy, the radial displacement influence of the focusing optical axis is minimum, in addition, the integral structure matching performance of a glimmer binocular telescope is good, meanwhile, the defect of single function of the objective lens focusing device of the existing glimmer binocular telescope is overcome.
Description
Technical field
The present invention relates to a kind of object lens assembly technology, belong to the precision optical instrument processing technique field.
Background technology
In order to improve the image quality of optical system, reduce the aberration of optical system, traditional way is to adopt advanced optical system design, complicated system architecture or adopt special structure and optical material.But these measures all will greatly improve the design and processing cost, and since processing installation method, effect is unsatisfactory, do not satisfy far away optical instrument particularly precision optical instrument to the requirement of image quality.
Object lens are important component parts of optical system, and it is directly connected to the system imaging quality good or not, and it is of a great variety, comprises telephotolens, photographic lens and microcobjective etc., though their service condition difference requires all very strict to image quality.In order to guarantee the image quality of optical system, in system's design, part processing and optics assembling, a lot of measures have been taked.The simplest direct method is to rely on the high tolerance of parts to cooperate, and adds the facing-up between part again, achieving the goal, yet, but improved design and processing cost.Transmission commonly used is the transmission picture that utilizes light beam process lens to form as method, being placed between parallel light tube and the microscope by the dress lens combination, rotates lens combination, and the departure of measurement picture is revised.Because beating of transmission picture is the resultant effect that two or more centre ofs sphere are beated, and the possibility of cancelling each other arranged, therefore, transmission is as transfixion when rotating lens combination, can not guarantee all centre ofs sphere in a straight line, that is to say that differing guarantees the coaxiality of lens surely.Autocollimatic reflection image method is at present near reality, method the most accurately, is used widely in the measurement of lens centering error already, and does not see as yet in the assembling of object lens to some extent and use.
Summary of the invention
The object of the invention just is to overcome above-mentioned deficiency, and a kind of object lens assembly technology is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of object lens assembly technology, described object lens assembly technology comprises following steps:
The first step: determine lens-mount axis and framework outside dimension according to the lens barrel optical axis;
Second step: calculate each lens imaging parameter;
The 3rd step: lens are installed on the machine tool chief axis by Hooks coupling universal coupling, and it is consistent with the lens barrel optical axis to determine to adjust lens axis;
The 4th step: according to the lens barrel internal diameter size, the maximum outer round surface of turning processing lens picture frame;
The 5th step: according to each lenticular spacing in the lens barrel, turning processing lens picture frame end face;
The 6th step: with in its lens barrel of packing into, namely finish the object lens assembling according to the position of arranging of each lens.
The maximum outer round surface size of lens picture frame and lens barrel internal diameter size build-up tolerance are 0.01 millimeter.
Object lens assembly technology of the present invention, more traditional object lens assembly technology has been guaranteed between lens and lens greatly, the alignment of optical axis between lens and lens barrel, improves image quality, has also simplified production run simultaneously greatly, use manpower and material resources sparingly, thereby reach the effect that has reduced production cost.

Embodiment
As shown in Figure 1, a kind of object lens assembly technology, described object lens assembly technology comprises following steps:
The first step: determine lens-mount axis and framework outside dimension according to the lens barrel optical axis;
Second step: calculate each lens imaging parameter, according to the optical parametric of autocollimation centre of sphere instrument and lens, calculate the luminous point of two curved surfaces of lens as position, distance, the position of objective tube and the lattice number of permission autocollimatic image jump at place according to object lens position, corresponding magnification, scale value and the offset index request of grid graticule;
The 3rd step: lens are installed on the machine tool chief axis by Hooks coupling universal coupling, and it is consistent with the lens barrel optical axis to determine to adjust lens axis, the band frame lens on the good limit of roller are connected with universal aligning device, and be fixed to together on the main shaft of lathe, adjust the position of autocollimation centre of sphere instrument and object lens thereof, until the luminous point picture that in autocollimation centre of sphere instrument eyepiece, can clearly observe first curved surface.At this moment, rotate the main shaft of lathe, and adjust universal aligning device, make the luminous point picture in the scope of the lattice number that the movement locus on the autocollimation centre of sphere instrument graticule is being stipulated;
The 4th step: according to the lens barrel internal diameter size, the maximum outer round surface of turning processing lens picture frame, the maximum outer round surface size of lens picture frame and lens barrel internal diameter size build-up tolerance are 0.01 millimeter;
The 5th step: according to each lenticular spacing in the lens barrel, turning processing lens picture frame end face;
The 6th step: with in its lens barrel of packing into, namely finish the object lens assembling according to the position of arranging of each lens.
