Abstract
A back supporting structure of a reflecting mirror is characterized in that three triangular brackets connected with a substrate are arranged on the substrate on the back of the reflecting mirror and are distributed on the circumference of a circle with the center of a circle of the substrate serving as the center of a circle at the equal angular distance; one or more supporting points are arranged on each triangular bracket, wherein the numbers of the supporting points on the three triangular brackets are identical. The method that multi-point supporting is converted into three-point supporting is designed, the problem that due to multi-point supporting, positioning is difficult is effectively solved, the shortages that adjustment is difficult and heat stability is influenced are overcome, the gravity deformation problem of the reflecting mirror is well solved, and the ideal surface figure accuracy is obtained.
Description
Technical field
The design relates to back of reflecting mirror supporting construction, belongs to the field of mechanical technique in optical field.
Background technology
Heavy caliber principal reflection mirror is as the vitals of optical sensor, and its surface figure accuracy directly affects the quality of image quality, and its support structure designs is the gordian technique of development optical sensor always.Good supporting construction can be improved a face shape for optical element effectively, therefore, needs supporting construction reasonable in design to meet the face shape requirement of heavy caliber principal reflection mirror.
Summary of the invention
For above-mentioned requirements, the design's object is to provide a kind of back of reflecting mirror supporting construction, effectively to reduce the gravity deformation of catoptron.
For achieving the above object, the design realizes by following technological means:
A kind of back of reflecting mirror supporting construction, is characterized in that: on back of reflecting mirror substrate, be provided with three triangle brackets that are connected with substrate, described three triangle brackets distribute at the first-class angular distance of the circumference with the substrate center of circle; On described triangle bracket, be provided with to quantity respectively etc. the more than one strong point.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: described triangle bracket and substrate flexibly connect.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: the centre of support of described three triangle brackets is positioned on the circumference taking the substrate center of circle as the center of circle.

Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: the circle diameter at gable top strong point place is less than the circle diameter at two strong point places of triangular base.
The invention has the beneficial effects as follows: the design is by the method for " multi-point support becomes 3 points ", efficiently solve the bad orientation problem of multi-point support, be difficult to debug, affect the defects such as thermal stability, the gravity deformation problem of having improved well catoptron, has obtained desirable surface figure accuracy.
Brief description of the drawings
Fig. 1 is back of reflecting mirror supporting construction schematic diagram, 9 support system schematic diagram that Fig. 2 is catoptron.
The implication of drawing reference numeral is as follows: 1 triangle bracket, 2 strong points, 3 triangle bracket centres of support, 4 substrates.
Embodiment
Below in conjunction with Figure of description, design is further described.
As shown in Figure 1, 2, a kind of back of reflecting mirror supporting construction, is characterized in that: on back of reflecting mirror substrate 4, be provided with three triangle brackets that are connected with substrate 1, described three triangle brackets 1 distribute at the first-class angular distance of the circumference with substrate 4 centers of circle; On described triangle bracket 1, be provided with to quantity respectively etc. the more than one strong point 2.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: described triangle bracket 1 flexibly connects with substrate 4.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: the centre of support 3 of described three triangle brackets 1 is positioned on the circumference taking the substrate center of circle as the center of circle.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: the strong point 2 on described three triangle brackets 1 is three.
The supporting construction that directly uses 9 strong points, will there will be orientation problem, not only be difficult to debug, and also can bring impact to thermal stability.Therefore, in support structure designs process, adopt the method for designing of " become 3 points " at 9, be about to 9 strong points and be divided into 3 groups, every 3 strong points are connected with a triangle bracket, between triangle bracket and substrate, link together by flexible link, and this flexible ring is energy-conservation enough small deflection, there is certain rigidity simultaneously, thereby realized " become 3 points " supporting construction at 9.This supporting way is on the basis of supported at three point, on the strong point of each static determinacy, by one deck triangle bracket, supporting is counted and is expanded as 9, remakes for catoptron.Because triangle bracket itself is static determinacy, the size that therefore acts on catoptron anchorage force is not independent of one another, but obeys statical equilibrium rule.Therefore, to anchorage force, it is a statically determinate system, but to catoptron elastic deformation, it is hyperstatic, can improve well the gravity deformation of catoptron.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: three described strong points 2 form an isosceles triangle.
Preferably, described a kind of back of reflecting mirror supporting construction, is characterized in that: the strong point 2-1 that is positioned at isosceles triangle top is positioned on the circumference with the substrate center of circle, and two strong point 2-2 that are positioned at isosceles triangle bottom are positioned on the circumference with the substrate center of circle.
