Abstract

The present invention disclosed a digital assembly manufacturing method of welding pipelines. The basic data of digital sampling is obtained through laser tracking measuring, the modeling completes the solution of the virtual boundary conditions of the pipeline, and the manufacturing of parts is completed according to the model data.Compared with the existing technology, the positive effect of the present invention is: the present invention uses the laser tracking meter measurement system for data measurement, the measurement accuracy is high, the real -time fast, the operation is simple, and the pipeline boundary feature measurement can be performed quickly and accurately; the invention is replicated by the present invention.The pipeline assembly space to the parts of the parts, the operating environment is single and the space is large, which avoids the risk of damage instruments; eliminates the time when the spacecraft's assembly needs to be waited for the manufacturing of the welding pipeline;The data of the space location is produced and manufactured. The data supports excessive dependence on artificial experience and improves the quality and assembly accuracy of pipeline production.

Description

technical field [0001] The invention relates to the technical field of pipeline assembly and manufacturing, and is mainly applied to a method for accurately measuring the boundary conditions of tailor-welded pipelines and performing digital assembly and manufacturing. Background technique [0002] Due to factors such as spacecraft parts and assembly errors, as well as the cumulative assembly errors of each component, some pipelines cannot be produced according to the theoretical dimensions of the drawings. After the corresponding sections or pipelines are connected by the final assembly, tailor-welded manufacturing is carried out according to the actual assembly space. to meet the assembly requirements. Therefore, in spacecraft, tailor-welded pipelines usually adopt the production mode of on-site physical sampling and manufacturing. When the final assembly reaches the corresponding section, the on-site physical sampling of the pipeline is carried out, and then it is returned...
