Description

Auxiliary marking device for bearing cylinder type satellite cabin

Technical Field

The utility model relates to the technical field of space, concretely relates to supplementary marking device in load cylinder type satellite cabin body.

Background

In recent years, the space technology in China is rapidly developed, a large number of various satellites emerge, and the trend of diversification and complication of satellite platforms is more obvious. Satellite development is a complex system engineering, wherein satellite assembly is an important link of satellite development, and has direct and important influence on ensuring overall performance, function and reliability of the satellite. The satellite assembly comprises assembly and component assembly, functional assembly, cabin assembly and whole satellite assembly. The main structure of the satellite is a central force bearing cylinder type structure, a wall plate type structure, a truss type structure and the like, and the force bearing cylinder type satellite structure part is formed by assembling a force bearing cylinder, a structure plate and a directly-belonging part into a cabin section or an integral satellite structure through processes of screwing, gluing and the like.

The cabin partition plate and the structural plate are skeleton parts of the whole star structure, and in order to better ensure the bearing performance of the structure, the bearing cylinder and the cabin partition plate are fixedly connected by metal connecting pieces around the star bearing cylinder.

In the actual installation process, on one hand, the cabin body partition plate connecting hole is a blind hole, and the through hole of the connecting piece cannot be directly prepared from the back when the cabin body partition plate connecting hole is connected with the connecting piece. On the other hand, because the composite material processing error is inevitable, the bearing cylinder is not theoretically circular but has certain deformation, and the situation can cause uncertainty in the connection position of the other side and the cabin partition plate after the metal connecting piece is connected with the bearing cylinder. Therefore, most communication bearing barrel type satellites in China adopt the metal connecting piece to be connected with the bearing barrel in a trial mode, and the connecting hole of the part, connected with the metal connecting piece, of the cabin partition board is prepared after the actual connecting position of the cabin partition board is locked. In the process of transferring the hole site of the partition board to the connecting piece, the scribing operation is involved, the conventional scribing operation is basically realized by utilizing the matching operation of the height gauge and the square box on the platform, the scribing positioning precision is high, and the operation is simple and convenient. The work of preparing holes on the bearing cylinder type partial platform belongs to the marking operation in space, the side wall of the bearing cylinder is in an oval shape, each angle bar is distributed on different three-dimensional spaces, no reference can be used, the marking operation cannot be completed by using conventional methods such as height gauges and square gauges, and in addition, the star space restriction is caused, so that the operation is very inconvenient. The traditional operation method is to paste an adhesive tape on the periphery of the connecting hole of the cabin partition board, transfer the hole position by taking the adhesive tape as a transfer through a manual wire hanging method, and realize the position transfer of the connecting hole. And the scribing operation is carried out by the right-angle block auxiliary scriber. Such an operation method has a large error, resulting in deviation of the positional accuracy after hole preparation.

It can be seen that the conventional method for preparing holes for cabin partition connectors has the following disadvantages: 1) the uncertainty is large, the operation can not be carried out by means of an industrial measuring tool and completely depends on visual operation, and the requirement on the skill level of an operator is high; 2) the accuracy is poor, the position needs to be visually transferred twice in the center of one hole, and the accuracy is low due to twice scribing coupling; 3) the hole making position degree is poor, and the later repair rate is high; 4) the hole site after repairing can't become the configuration hole of riveting layer board nut or location tie point.
