Description
Technical field
The present invention relates to a kind of catoptron method for supporting.
Background technology
In optical instrument, adopt devitrified glass as reflecting material, be the most ripe, the most frequently used optical reflection imaging means.Adopt devitrified glass as catoptron, can reduce material cost and processing cost, its surface is plated film without modification and directly, has increased reliability of technology.
Because devitrified glass is traditional reflecting mirror material, its elastic modulus is low, and catoptron receives the erection stress effect to cause distortion when assembling easily; Simultaneously because the devitrified glass temperature conductivity is less with specific heat, thus catoptron when work, catoptron is subject to variation of ambient temperature generation thermal deformation and influences image quality.These characteristics have determined mirror assembly in assembling process, will be in microstress state or unstress state all the time, and supporting construction has good thermal adaptability.
Small-bore devitrified glass catoptron tradition adopts the supporting way that frames up, this complex structure, and weight is big, and the mode that compresses all around is easy to generate optical aberrations such as the curvature of field, astigmatism.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiency of prior art, the small-bore devitrified glass catoptron microstress assembling flexible support method that a kind of supporting construction is simple, vibration frequency is high, damping property is good is provided.
Technical solution of the present invention is: small-bore microcrystal glass material catoptron microstress assembling flexible support method, and step is following:
(1) carries out lightweight processing at the back of catoptron, and process newel in the centre position of back of reflecting mirror;
(2) processing flexibility mandrel; Described flexible mandrel is one and has certain thickness equilateral triangle structure; Three angles of equilateral triangle respectively are processed with the link of a rectangular structure; The centre of equilateral triangle is processed with a hollow cylinder that cooperates with newel, and cylindrical inside has three reinforcements that angle is 120 degree, is processed with the through hole of three place's rectangles between cylinder and the link; The root of said link is processed with flexible spron, and the bottom of flexible spron is an arc section, and the head of said link is processed with mounting hole and pin hole;
(3) inside surface with the newel of the cylindrical outer surface of flexible mandrel and back of reflecting mirror bonds together.
Described flexible mandrel is a titanium alloy material.
Spron on described each link has two, and the opening direction of two flexible sprons is opposite, and both sides and two the flexible sprons at its place link are parallel to each other respectively.
Described cylinder and newel adopt unstressed glue when bonding.
The present invention's advantage compared with prior art is:
(1) location that the inventive method adopts catoptron and the direct bonding mode of mandrel has realized catoptron; Under the prerequisite that guarantees the mandrel machining accuracy; Catoptron can realize very high bearing accuracy, overcome the deficiency of optical aberrations such as the curvature of field that traditional approach compresses generation, astigmatism;
(2) in mandrel and extraneous screw connection portion position, be provided with flexible spron, thereby realized radial and axial flexibility simultaneously, this is simple in structure, in light weight, vibration frequency is high, damping property is good;
(3) when ambient temperature level has greatly changed, mandrel can produce the elongation and the compression of spring-like with extraneous connecting portion, thereby can absorb extraneous carrier thermal deformation ability, and catoptron at this moment can be in relative free state and be protected;
(4) when assembly assembles; The installed surface flatness tolerance of the installed surface of connecting portion and carrier can not be in full accord; Under the effect of screw pretightning force, corresponding up and down spron bends, and the erection stress of this moment is with respect to reducing greatly under the situation that spron is not set; Thereby realized the microstress assembling, catoptron is protected thus.

Embodiment
As shown in Figure 1, for adopting the reflecting mirror support structure synoptic diagram after the inventive method supports, the key step of catoptron microstress assembling flexible support method of the present invention is following:
(1) as shown in Figure 2; Carry out lightweight processing at the back of catoptron 1; The lightweight form can be become (having adopted triangle, quadrilateral and circular as the lightweight form in the accompanying drawing) by regular graphical set such as triangle, quadrilateral, hexagon and circles; Newel 101 is a mounting hole, and inside surface need grind to guarantee its cylindricity and then to guarantee bonding precision and bonding reliability;
(2) like Fig. 3 and shown in Figure 4; Flexible mandrel 2 is equilateral triangle structures; The centre processes a hollow cylinder 201; Three angles respectively process the link 202～204 of a rectangular structure, and the identical through hole 205 (being two pairs of rectangles in the accompanying drawing) of processing three place's shapes is used for weight reduction between cylinder 201 and the link 202～204.Cylinder 201 inside have three reinforcements that angle is 120 degree; The outside surface axis coaxial with catoptron 1 back cylinder 101 inside surfaces and assurance cylinder 201 that will guarantee cylinder 201 simultaneously is vertical each other with the installed surface of link 202～204; Avoid when bonding because 201 outside surface and 101 inside surfaces cause erection stress to produce because of form and position tolerance is overproof, and then influence the performance of mirror assembly.Respectively process two flexible sprons 208 at link 202～204 roots; The bottom of flexible spron 208 is one circular-arc; This shape has avoided the spron root to produce concentrated stress; Article two, the opening direction of flexible spron 208 is opposite; Belong to the both sides of link and guarantee that two flexible sprons 208 are parallel to each other and flexible spron 208 is vertical each other with link 202～204 installed surfaces at it respectively, the opening direction difference of one group of flexible spron 208 on each link has realized radial and axial flexibility, can absorb mirror assembly has guaranteed supporting construction because of the various stress deformations of assembling and temperature is brought precision.Process at least two mounting holes 206 and at least one pin hole 207 at link 202～204 heads, flexible mandrel 2 adopts titanium alloy material;
(3) as shown in Figure 1; Cylinder 201 outside surfaces through flexible mandrel 2 and cylinder 101 inside surfaces of devitrified glass catoptron 1 are directly bonding; Use unstressed glue when bonding, the curing initial stage need adopt frock to keep compressing, and the curing later stage removes frock makes glue-line outwards discharge solidification internal stress; To guarantee final bonding precision, whole solidification process need be by the instructions controlled humidity and the temperature of unstressed adhesive curing;
(4) mirror assembly after bonding is connected on the carrier through mounting hole on the link 202～204 206 and pin hole 207, positions with pin earlier, with screw mirror assembly and carrier are fixed again, accomplish the assembling of whole assembly.
The content of not doing to describe in detail in the instructions of the present invention belongs to those skilled in the art's known technology.
