Embodiment Construction
[0017] Below in conjunction with accompanying drawing and specific embodiment content of the present invention is described in further detail:
[0018] Such as Figure 1 to Figure 7 The shown flexible support device for a lightweight reflector includes a reflector 1 , a flexible annular support base 2 , a connecting frame 3 , a push rod 4 and an installation platform 5 . The front of the reflector 1 is an optical working surface, and the back is a spoke-type weight-reducing structure. There is a circular support hole in the center of the back. There are six reinforcing ribs evenly distributed around the circular support hole, that is, the weight of the reflector is reduced under the condition of ensuring the overall strength and surface shape of the reflector.
[0019] The flexible annular support base 2 is arranged in the support hole of the reflector 1. The flexible annular support base 2 is in the shape of a ring as a whole, and three arc-shaped weight-reducing grooves 21 ...

The invention provides a flexible supporting device for a light reflecting mirror, which mainly solves a technical problem that an existing device is easy to deform, twist, break and difficult to adjust in a mechanical vibration environment and a thermal variation environment. The supporting device comprises a reflecting mirror, a flexible annular supporting base, a connecting frame, an ejector rod and a mounting platform, and is characterized in that the obverse side of the reflecting mirror is an optical working surface, the reverse side of the reflecting mirror is provided with a circular supporting hole, and a plurality of reinforcing ribs are arranged around the supporting hole; the flexible annular supporting base is located in the supporting hole of the reflecting mirror, the edge of the flexible annular supporting base in the circumferential direction is provided with a stress relieving slot, the outer wall is provided with a plurality of bonding lining blocks connected with the reflecting mirror; the connecting frame is located between the flexible annular supporting base and the mounting platform, and the end face of the connecting frame is provided with a spherical slot which is matched with the ejector rod to form a motion pair; and the ejector rod comprises a screw and a ball head arranged at the top end, and the ejector rod is mounted on the mounting platform in a threaded connection manner. The flexible supporting device can be used for supporting and performing accurate adjustment on the attitude of the reflecting mirror in a space optical instrument.
Description
technical field [0001] The invention relates to the field of structural support of optical parts, in particular to a flexible support device for a lightweight reflector. Background technique [0002] With the further development of space optical science and technology, the requirements for the use of space optical instruments are getting higher and higher. In space optical instruments, the plane reflector is one of the essential key components. With the continuous improvement of space science and technology for precision requirements, the plane reflector must be able to ensure its optical performance under severe working conditions. Accuracy, but also requires the maximum reduction of its own weight. In addition, space optical instruments are precision equipment, which need to withstand various environmental tests such as heat and mechanics. As an important component, the reflector is subject to harsh mechanical vibration environment and thermal change environment during s...
