Problems solved by technology

The waiting time for final assembly caused by the traditional "serial manufacturing" of on-site physical sampling and manufacturing has seriously affected the efficiency of final assembly of models, and it is no longer suitable for the development trend of digital manufacturing of launch vehicles, and can no longer meet the needs of the development of new models such as heavy-duty vehicles. The disadvantages of the "serial manufacturing" mode are becoming increasingly prominent, and it is urgent to adopt effective methods to realize the precise and efficient manufacturing of such sampling catheters

Abstract

The invention relates to a guide pipe digitization sampling and manufacturing method based on an actual assembly space on a rocket, and belongs to the technical field of advanced manufacturing of carrier rockets. The method includes the steps of installing four fuel tank guide pipe mounting flanges on the bottom of a fuel tank; installing four engine start valve guide pipe mounting flanges; conducting butt jointing on fuel tank mounting butt rings and engine mounting butt joint rings; measuring coordinates of the corresponding fuel tank guide pipe mounting flanges in a reference coordinate system o3x3y3z3 and vectors in three directions; simulating the relative positions of the engine start valve guide pipe mounting flanges and the fuel tank guide pipe mounting flanges; installing a firstto-be-installed guide pipe; repeatedly executing the step four to the step six three times to obtain the other three to-be-installed guide pipes; and judging assembly gaps. The guide pipe digitizationsampling and manufacturing method solves the problem that the requirement for final precise butt assembling on the rocket can be met only when the guide pipes are produced according to the actual assembly space on the rocket.

Description

technical field [0001] The invention belongs to the technical field of advanced manufacturing of carrier rockets, and relates to a digital sampling manufacturing method for conduits based on the actual assembly space on the rocket. Background technique [0002] Due to the manufacturing error of the rocket body, the manufacturing and assembly error of the engine, and the cumulative assembly error of each component, some tailor-welded ducts must be manufactured according to the actual assembly space on the rocket body to meet the requirements of precise docking assembly. In active launch vehicles, this kind of tailor-welded duct usually adopts the production mode of on-site physical sampling and manufacturing. After the final assembly reaches the corresponding section, the on-site physical sampling of the duct is carried out, and then returned to the manufacturing workshop for duct manufacturing, and then to the final assembly workshop. Trial assembly, after meeting the assemb...
