Good processability, the mirror body of rectangular metal reflecting mirror is integrated with flexible support structure to be shaped.It is required that mirror structure has
Good static rigidity and stability, high dynamic rate and intensity, high thermal stability.This means that reflecting mirror in the external world
The dynamic loads such as stable state or gradient temperature variation, Gravity changer, receiving vibration and impact occur and mechanical interface flatness becomes
After change, biggish structural stress will not be generated, installation alignment precision and surface figure accuracy cannot generate large change, still ensure that
The image quality of off-axis three anti-Space Optical System.Therefore, high static and dynamic structure rigidity, high thermal stability and mirror body can
Keeping the rectangular metal reflecting mirror flexible support integral structure of installation and surface figure accuracy with unstress state is that design is novel low
The key technology of the anti-space optical remote sensor of cost lightweight off-axis three.
Closest prior art is Changchun Institute of Optics, Fine Mechanics and Physics, CAS with the present invention
Model builds the infrared off-axis system metallic mirror structure proposed on " infrared technique " periodical in May, 2015.The reflecting mirror knot
Structure is as shown in Figure 1, comprising: 1, mirror body, 2, positioning adjustment screw hole, 3, installation screw hole, the 4, first flexible slot, 5, second is flexible
Slot, 6, third flexible slot, 7, installation interface surface, 8, flexible leg.Uniformly designing on the periphery of mirror body 1 has installation interface 7 at three,
Every place's installation interface 7 is integrally formed by two flexible legs 8 with mirror body 1.Have in the middle position design of every place installation interface 7
Positioning adjustment screw hole 2 at one, adjusts screw by screwing in a bulb respectively in adjustment, realizes entire mirror body spatial position
3 points adjustment.Every place's installation interface 7 is also devised with location and installation screw hole 3 at two, is realized by screwing in a screw respectively
Installation to mirror body.The first flexible slot 4, the second flexible slot 5 and third flexible slot 6 are respectively designed in every place's flexible leg 8
Flexible hinge at totally three, thermal stress caused by caused concentrated stress and temperature change when for unloading installation.This installation skill
The shortcomings that art, is: a) the flexible support structure need by bulb adjust screw manually adjusted, installation repeatability with can
Surface deformation is easy to cause when and adjustment lower by property；B) all flexible links are gap formula flexible hinge, are not provided flat
Dynamic freedom degree, it is difficult to realize the compensation of thermal deformation difference；C) precision engineering is not fully demonstrated in the Combination Design of flexibility link
In kinematics positioning principle, there are the Planar Mechanisms to mirror body.
Summary of the invention
In order to solve the problems, such as that prior art exists, present invention aims at meeting, the off-axis metallic mirror of rectangle is high
Under the premise of rigidity, high intensity, high stability, guarantee in the variation of gravitational field relative reflection mirror body coordinate system and ambient temperature
When changing a lot, the surface figure accuracy of reflecting mirror and the spatial position precision of installation are eliminated still in tolerance
Influence of the erection stress to reflecting mirror surface shape in reflecting mirror installation process, a kind of ad hoc one for counting off-axis metallic mirror of rectangle
Change flexible support structure.
It is as follows that the present invention solves the technical solution that above-mentioned technical problem is taken.
A kind of integrated flexible support construction of the off-axis metallic mirror of rectangle, including mirror body and three flexible supports；
Three flexible support circumference uniform distributions are arranged on the side of mirror body；
Each flexible support includes flexible board and two connected units；
Flexible board is fixedly connected with mirror body, and flexible board is equipped with installation positioning screw hole, the first flexible slot, the second flexible slot
With third flexible slot, the first flexible slot and the second flexible slot be it is arc-shaped, be arranged symmetrically relative to installation positioning screw hole, third
The middle section of flexible slot be it is arc-shaped, be arranged outside the first flexible slot and the second flexible slot, it is soft with the first flexible slot and second
Property slot is coaxial and perpendicular arrangement, the end of third flexible slot is along perpendicular to the symmetry axis of the first flexible slot and the second flexible slot
Direction extends out to flexible board edge；
Two connected units are separately fixed at the two sides of flexible board, and bottom end is aligned with the bottom surface of flexible board, and side and mirror body are solid
Fixed connection.
Further, the exposed outer peripheral shape of the flexible board and third flexible slot are relative to installation positioning screw hole
Symmetrically.
Further, two planes are cut on two adjacent right-angle sides of the mirror body, fix two flexible supports respectively,
Another flexible support is fixed on on two disjunct sides of cutting planes, and the central point of three flexible supports forms one etc.
Side triangle.
Further, first flexible slot and the second flexible slot are two disjunct semi arches.
Further, the mirror body back is machined with lightweight muscle.
The working principle of the invention: it is in 0 ° uniformly distributed that the integrated flexible support construction of rectangular metal reflecting mirror, which shares at three,
Flexible support, with installing the first integrally formed flexibility of wire cutting at positioning screw hole and three at one in every place's flexible support
Slot, the second flexible slot, third flexible slot, so that there are three the rotations relative to mirror body of mutually orthogonal direction for every place's mounting surface tool
Freedom degree, respectively along the axial translational degree of freedom with radial direction of mirror body, has left behind a translation tangential along mirror body with two
Freedom degree constraint.This just realizes the accurate installation positioning to mirror body.When gravitational field changes with respect to mirror body coordinate system, three
Place's flexible support can realize the Complete Bind to mirror body always, significantly reduce the variation of mirror shape precision；Simultaneously because
The presence of every place's flexible support, so that flexible support has the translation flexibility along mirror body radial direction.When ambient temperature becomes
Change cause mirror body and mounting structure thermally expand variable quantity it is inconsistent when, itself of short straight beam to be formed two is cut by flexible slot
Deformation is greatly reduced the variation of mirror shape precision and installation accuracy at this time to absorb strain energy；And when mounting structure
When flatness changes, since every place's flexible support tool is there are three the flexibility of rotational freedom and along the translation of mirror surface axial direction
Freedom degree is flexible, and the erection stress and mirror body that can introduce unevenness completely cut off, and absorbs strain energy by flexible link to keep mirror
The surface figure accuracy in face.For different dynamics environment and thermal environment, select suitable flexible ring section structure size that can guarantee
The rigidity and intensity of flexible support meet design needs.
Compared with prior art, beneficial effects of the present invention:
The integrated flexible support construction of rectangular metal reflecting mirror proposed by the invention reflects rectangular metal realizing
While mirror complete kinematics location and installation, by designing the integral type flexibility link at three in flexible support, it can subtract significantly
The mirror body internal stress generated in small Gravity changer, temperature change and assembling process, and guarantee surface figure accuracy and the installation of reflecting mirror
Positioning accuracy is under extraneous mechanics and Thermal Load without departing from the franchise value of optical design, processing technology and assembling process letter
Single, reliable operation is not necessarily to adjustment link.
