A kind of inflatable film reflector and its assembly tooling and assembly method

Abstract

The invention provides an inflatable film reflector and its assembly tool and assembly method. The film reflector is composed of a clip, a main mirror frame, a main mirror pressure plate, a polyimide film and a sealing ring: the assembly tool includes a connecting Frame, pressing plate, film frame, gland, nylon rope; the assembly method steps of described assembly tooling are as follows: the connection frame is fixed on the main mirror frame; The position of the main mirror pressing plate, pressing plate and film frame is fastened; The two films are tied to the film frame respectively, and the tension of the film is controlled by tightening the nylon rope, and the film is evenly tightened; the film frame is fastened to the gland, and then the gland is fastened to the connecting frame; finally Press the pressing plate, the main mirror pressing plate and the film tightly on the main mirror frame. The invention realizes the effective control of the ideal surface shape of the thin film by using the assembly tool, and improves the surface shape precision of the thin film reflector.

Description

technical field [0001] The invention belongs to the technical field of space optics, and relates to an inflatable film reflector, an assembly tool and an assembly method thereof. Background technique [0002] In recent years, with the rapid development of system structures for earth observation and military reconnaissance, the requirements for super-large and ultra-lightweight mirrors, which are the main components of space telescopes, camera systems, antennas, energy concentrators, and weak signal detectors, have become more and more serious. more and more urgent. The space thin-film mirror can meet the requirements of ultra-light weight and super-large aperture of the space mirror, and its development is of great significance to promote the development of space technology. [0003] Traditional mirrors use form-stable rigid materials such as glass, metal, and crystals. Due to their strong rigidity, high density, difficult processing, and high cost, these materials are dif...
