Embodiment Construction

[0028] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but it is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be covered by the present invention. within the scope of protection.

[0029] Such as figure 1 As shown, the overall structure of the film mirror and its assembly tooling is symmetrical on the central axis with respect to the main mirror frame 1 and the connecting frame, wherein the main mirror pressure plate 4, pressure plate 5, film frame 6, and gland 7 are two each and have the same structure. 16 clips 8 are responsible for pressing the main mirror pressing plate 4 tightly on the main mirror frame 1 from the outsides of the two main mirror pressing plates 4 . The assembly tooling consists of a connection frame, a gland...

Abstract

The invention provides an inflatable membrane reflector, and an assembly tool and an assembly method thereof. A membrane reflector is composed of a clip, a main mirror frame, a main mirror pressure plate, a polyimide membrane and a seal ring, wherein the assembly tool comprises a connecting frame, a pressure plate, a membrane frame, a pressure cover and nylon ropes; the assembly method of the assembly tool comprises the following steps: fixing the connecting frame on the main mirror frame; fastening the positions of the main mirror pressure plate, the pressure plate and the membrane frame; respectively binding two membranes on the membrane frame through the nylon ropes; controlling the tightening degree of the membranes by tightening the nylon ropes, and simultaneously, uniformly tightening the membranes; and fastening the membrane frame and the pressure cover, then fastening the pressure cover and the connecting frame, and finally pressing the pressure plate, the main mirror pressure plate and the membranes on the main mirror frame. Effective control on an ideal surface shape of the membrane is finished by the assembly tool; and the surface shape accuracy of the membrane reflector is improved.

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...
