Description
Technical field
This utility model belongs to optical engineering technical field, and in particular to a kind of large caliber reflecting mirror mounting structure.
Background technology
Principal reflection mirror is directly determined as the key element in the reflective primary optical system of heavy caliber camera, its surface figure accuracy
The image quality of telescope.With the increase of optical system bore, the diameter and weight of reflecting mirror can increase, in terrestrial gravitation
In the presence of, primary mirror can deform, so as to the image quality for causing optical system is reduced.In order to reduce the deformation of primary mirror,
The position of primary mirror support structure stress point is determined by analysis so as to which deformation is minimum, so as to obtain higher main mirror face precision.
To ensure the surface figure accuracy of primary mirror so as to be reduced to acceptable limit from the impact conducted oneself with dignity or by impact, design a fit
The primary mirror support structure of reason is particularly important.
The camera reflective optical system that at present ground uses is generally using the central shaft positioning and mounting structure of shaft hole matching
Such as Fig. 1, shown in 2, this supporting construction has the disadvantage that under current assembly technology：
1. shaft hole matching realizes that the radially, axially connection to primary mirror is supported, in the case where range of temperature is larger, easily
Cause, because the expand with heat and contract with cold additional stress that causes of central shaft can seriously reduce the surface figure accuracy of reflecting mirror, to cause system imaging matter
The decline of amount；
2. gluing area is big, and gum spot uniformity is uncontrollable, is easily caused primary mirror mating holes circumference annulus gluing segment stress not
, main mirror face is affected；
3. shaft hole matching finally adopts gluing fixation, is completed by disposable injecting glue, not readily removable glue after curable adhesive layer, increases
Tear glue difficulty open and debug risk.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of rigidity height, good environmental adaptability, easily
The Novel camera reflecting mirror support structure of assembling.
A kind of heavy caliber camera Reflecting mirror installation structure of the present utility model, including reflecting mirror and central shaft, its it is special it
Place is：
The central shaft has Auxiliary support section and main supporting section, between the Auxiliary support section and mirror center hole axle hole
Gap carries out auxiliary and is fastenedly connected with merga pass injecting glue；
The main supporting section is located at back of reflecting mirror, and the main supporting section is main support face near the face of back of reflecting mirror,
Multiple mounting grooves are provided with the main support face；
The Reflecting mirror installation structure also includes multiple viscose glue pressure heads, and the plurality of viscose glue pressure head correspondence is arranged on multiple peaces
In tankage；
It is fixedly connected by binding agent between the back of reflecting mirror and multiple viscose glue pressure heads.
It is above basic structure of the present utility model, based on the basic structure, this utility model also makes following optimization limit
It is fixed：
The fit clearance in above-mentioned Auxiliary support section and mirror center hole is controlled between 0.1-0.2mm.
Above-mentioned Auxiliary support section is peripherally disposed the viscose glue boss parallel with axle body, along viscose glue boss centre normal
Direction is provided with hole for injecting glue, and viscose glue boss surface is along the circumferential direction provided with the guiding gutter of square crossing with axle body direction, intersects
Point passes through hole for injecting glue.
Above-mentioned viscose glue pressure head is multidiameter form, and the periphery at big end is provided with anti-rotational boss；Small end is viscose glue end, big end
It is peripherally disposed with small end ladder to have stress-removal groove.
Above-mentioned big end is inwardly provided with screwed hole along its axial end；
The main supporting section along its it is axially arranged have and hold greatly the through hole that communicates of screwed hole,
The supporting section also includes and viscose glue boss quantity identical screw that the screw is worn successively from main supporting section outside
Cross through hole and compression viscose glue boss is threadedly coupled with screwed hole.
Compared with prior art, advantage is this utility model：
1st, by the main support in back, axis hole Auxiliary support improves mirror support efficiency to this utility model, increases anti-
Penetrate mirror support safety coefficient.
2nd, back support is completed by the gluing pressure head being installed on reflecting mirror axle, and it is controllable to realize gum spot size, is eliminated
Because gum spot differs in size the reflecting mirror surface shape error caused to the additional stress inequality that reflecting mirror is produced, pressure head viscose head
Stress-removal groove is set, while dynamic is ensured with static structure rigidity, can effectively be eliminated camera body stress and deformation is right
The impact of reflecting mirror, reduces the impacts of the factor to reflecting mirror surface shape such as temperature change, gravity.
3rd, reflecting mirror axle is bolted connection with gluing pressure head, improves reflecting mirror easy in the case of gluing error
Tearing open property, so as to reduce resetting difficulty and risk.
4th, the clearance control of axis hole Auxiliary support is between 0.1-0.2mm, it is to avoid lead because reflecting mirror axle expands with heat and contract with cold
The reflecting mirror surface shape trueness error of cause, while being provided with guiding gutter being glued at face, is conducive to adhesive glue uniformly to spread, and forms equal
Cloth gum spot, improves surface figure accuracy.
