Pressurization device for installing heaters on complex curved surfaces of spacecraft

Abstract

The invention discloses a pressurizing device used for mounting a mounting complex curved surface heater of a spacecraft. The pressurizing device comprises a bridge type support, an adsorbing module, a sliding block, a ball-headed pin, a pressure plate, a flexible forming block and a butterfly adjusting bolt, wherein a long hole is formed in the center at the upper part of the bridge type support, strip-shaped through holes are formed in the two ends of the bridge type support, the two ends of the bridge type support are tightly compressed and connected onto the adsorbing module through a sucker screw and a big nut, the butterfly adjusting bolt penetrates through the sliding block, the long hole above the bridge type support, and the ball-headed pin in sequence, and is in screwed connection to a threaded hole in the center of the pressure plate, the flexible forming block is arranged at the bottom of the pressure plate, the sliding block can slide in the lengthwise direction of the bridge type support, and is fixed through the butterfly adjusting bolt, and the butterfly adjusting bolt is used for adjusting screwed thread turns to control pressing force. The pressurizing device provided by the invention solves the problem that pressuring on a large vertical curved surface in the horizontal direction can not be performed, the dismounting of the device is simple and easy, the use is flexible, the adjustability is high, and for irregular regions, the pressurizing device plays an excellent assisting effect on mounting the heater in an operation limited position.

Description

technical field [0001] The invention belongs to the technical field of spacecraft assembly, and in particular relates to a set of pressurizing tooling for installing a manned spacecraft polyimide film type electric heater. Background technique [0002] The heater is the basic guarantee for the normal operation of the instruments and equipment in the cabin of the manned spacecraft and the safety of the astronauts. At present, the installation of polyimide film-type electric heaters for manned spacecraft adopts the following methods to apply pressure and solidify: heavy objects (sandbags) pressurize and elastic bands fix pressurize. [0003] Sandbag pressurization is suitable for pressurization on a horizontal plane or a surface with a small curvature in the horizontal direction. A sandbag with uniform sand grains is stacked on each pasted electric heater to prevent the sandbag from slipping in the warp and weft directions. This method relies on the weight of the sandbag to p...
