Abstract
The invention discloses a flexible supporting structure for the back of a reflecting mirror, relating to the technical field of precision machinery for optical systems; the supporting structure comprises an upper ring (1), a lower ring (2), a first flexible element (3), a second flexible element (4) and a third flexible element (5); the upper ring (1) is fixed on the body of a camera, the lower ring is adhered to the back of the reflecting mirror, and the first flexible element (3), the second flexible element (4) and the third flexible element (5) are all positioned between the upper ring (1) and the lower ring (2) and connect the upper ring (1) with the lower ring (2). During the assembly of components of the reflecting mirror, the flexible supporting structure leads the operation simple and reliable and avoids assembling stress caused by conducting a plurality of operations to the reflecting mirror.
Description
Technical field
The invention belongs to optical system precision machinery technology field, can be applicable to the back support of the following bore catoptron of 300mm in space remote sensing camera or the ground telescopic system, relate to a kind of back of reflecting mirror flexible support structure.
Background technology
Along with from the application of axle astigmation free optical system on space camera, big medium caliber catoptron is used multiple spot back support mode usually, along with the fast development of using in the space from the axle astigmation free optical system, the back support of the small-bore catoptron of centering also needs to seek the mode of solution.In being applied to as the multiple spot back support mode that the large caliber reflecting mirror back support is adopted on the small-bore catoptron, will be less, and make the structural member size of back support reduce owing to the back of reflecting mirror area, the difficulty of processing that it brings thereby be multiplied.And the multiple spot back support need be implemented than large tracts of land, in small-bore catoptron, its occupation proportion is bigger, and the lightweight degree is reduced greatly, mirror quality increases.As adopt traditional outer box form stationary mirror, and will be bigger owing to mirror size, the also inevitable corresponding increase of the size of its required housing and thickness also makes catoptron weight increase greatly.
Summary of the invention
In order to solve the problem in the background technology, the object of the invention aims to provide a kind of medium and small back of reflecting mirror supporting construction in the axle astigmation free optical system of sound attitude rigidity preferably that has, satisfy unfavorable factor such as temperature, microgravity in the space environment, and make things convenient for the assembling of mirror assembly, the erection stress that reduces to produce in the assembling process.
In order to achieve the above object, technical scheme of the present invention is as follows:
A kind of back of reflecting mirror flexible support structure, comprise ring, following ring, first flexible piece, second flexible piece and the 3rd flexible piece, last ring is with ring is parallel down, last ring is fixed on the camera body by backboard, following ring is bonding with back of reflecting mirror, be mutually 120 ° of angles between first flexible piece, second flexible piece and the 3rd flexible piece, three flexible pieces are all at last ring and down between the ring, and will go up ring and be connected with encircling down.
The present invention is divided into two parallel rings with existing support ring, by the flexible piece in the structure, weakens the ability of Stress Transfer layer by layer, makes reflecting mirror surface shape reduced by stress influence.
The invention has the beneficial effects as follows: the present invention combines supported at three point and central supported, with each required degree of freedom constraint of simple composite and flexible spare cremasteric reflex mirror back support, satisfy mechanics requirement to catoptron, when using the bigger propping material of relative reflecting mirror material expansion coefficient, still can in bigger temperature range, satisfy the calorifics requirement of catoptron.In assembling process, operation is simple and reliable, avoids the erection stress that repeatedly operation brings to catoptron.

Embodiment
Below in conjunction with accompanying drawing the present invention is done description in further detail:
Extremely shown in Figure 8 as Fig. 1, a kind of back of reflecting mirror flexible support structure of the present invention, comprise ring 1, encircle 2, first flexible piece 3, second flexible piece 4 and the 3rd flexible piece 5 down, last ring 1 is the becket that is parallel to each other with encircling 2 down, become the flexible piece of 120 ° of angles to connect with three therebetween, under encircle 2 bonding with back of reflecting mirror, on encircle 1 and be fixed on the relevant position of camera body by backboard.
The horizontal projection of first flexible piece 3 such as II view, tangent projection such as III view, the horizontal projection of all the other two flexible pieces is identical with the projection structure of first flexible piece 3 with the structure of tangent projection.The projection of first flexible piece 3 on two rings up and down is oval 6, oval 6 by first beam 7 and second beam 8 respectively with last ring 1 and down ring 2 be connected, its effect is to be subdued and isolated by the stress of transmission of catoptron backboard and generation and catoptron.By the stress that backboard produces and transmits, in the configuration process that is delivered to as the II view, because bang path attenuates, structural flexibility increases, and has reduced to be delivered to oval 6 stress, oval 6 distortion is far smaller than encircles 1 distortion.Again by same path be delivered to the bonding following ring 2 of back of reflecting mirror on, another has reduced stress and distortion.Encircle down 2 with the bonding position, three places of catoptron (as among the figure a) with the staggered 60 ° of distributions of three flexible pieces, make the stress that is delivered to down on the ring 2 in the catoptron transmittance process, decay once more.The back lightweight form that catoptron adopts is subjected to back support stress minimum once more with stress decay to guarantee reflecting mirror surface shape, reduces the influence of stress to reflecting mirror surface shape.
Catoptron adopts the lightweight form of a cylinder of back projection, and supporting construction of the present invention is bonded on the wall of cylinder and root by optical cement, and interface b is connected on the backboard with screw and pin.
The present invention has tried out in the multispectral camera of a camera of China's sky remittance, has obtained good effect.Its catoptron uses micro crystal material, mirror size 248mm * 164mm, and two support rings adopt expansion coefficient 0.18 * 10
-6The indium steel, its The results, under gravity and 15 ℃ of temperature rise effects, the unified deformationization of catoptron is less than 1/50 wavelength.Debug in the process in catoptron processing and system, also show tolerable temperature variation characteristics greatly.After camera lens, unit, system-level mechanics and calorifics test, basic not variation.
