Detachable flexible support device

Abstract

The invention provides a detachable flexible support device comprising a reflector the body of which is provided with a circumferential flange surface; and at least three flexible support members connected with the reflector and uniformly distributed on the circumferential flange surface. Each flexible support member is provided with a countersunk hole, a pin hole, a threaded hole and at least onepair of staggered orthogonal flexible slots. The detachable flexible support device can reduce flexible machining difficulty and can increase the lightening rate of the reflector.

Description

technical field [0001] The invention relates to the field of optical remote sensing technology, in particular to a detachable flexible support assembly. Background technique [0002] The development trend of space optical remote sensor optical system is high light weight rate, light and small size, high resolution, high integration and high cost performance. High-precision mirrors are of great significance for aerospace payloads. The optical system can obtain high-definition photos in fields such as ground reconnaissance, remote sensing, and detection, and can be widely used in civilian, military, and national defense fields. With the development of single-point diamond turning technology (SPDT), metal-based mirrors are successfully used in optical imaging systems with the advantages of rapid and low-cost manufacturing. [0003] Metal reflectors are cost-effective and have good machinability. They can be directly drilled or tapped on the reflector. It is easy to realize th...

Problems solved by technology

However, the flexible support structure of the reflector has the following disadvantages: a) the integrated design of the flexible support and the mirror body, the centrifugal deformation of the mirror surface is likely to occur due to the existence of the flexible link in the process of mirror mirror surface processing, so it is only suitable for the support design of small and medium-diameter reflectors; b) The flexible support structure and the mirror body are designed in an integrated manner, and the flexible groove of the flexible support structure is difficult to process; c) The back of the mirror and the support structure interfere with each other, which is not conducive to achieving a higher lightweight rate; d) The mirror The support stiffness of the flexible support structure is limited, which is only suitable for small and medium aperture optical systems

This structure is mostly used in the flexible support structure of super-large-diameter non-metallic reflectors, and has the following disadvantages: 1. The support structure is complex, including reflectors, flexible joints, taper sleeves, and multiple installation links; 2. The process is complicated and the reflection The mirror and the tapered sleeve are fixed by glue bonding. During the bonding process, the stability of the mirror surface shape needs to be monitored. If the bonding fails, it will take a lot of time to clean the foam and the cycle will be longer.

This support structure suitable for small-aperture mirrors has low support rigidity, and there is a problem of uncontrollable deformation of adhesive parts. This solution is similar to Document 2, except that it contains a kinematic adjustment mechanism to adjust the angle of the mirror.
