Embodiment

[0018] A method for extracting pipeline weld seam information based on a three-dimensional design model, the steps of which are as follows:

[0019] (1) Follow the naming rules of the following model files when establishing a PROE-based pipeline component assembly model: the pipeline component assembly model naming rule is: model code_cabin / subsystem_component code.ASM; pipeline model The naming rule is: model code_cabin / subsystem_component code_PIPE three-digit natural number serial number.PRT; the naming rule of the weld model is: WELD_model code_cabin / subsystem_component code_two-digit natural number serial number .PRT. Other assembly components (e.g. valve bodies, filters) are coded and must be differentiated from piping components, piping and welds.

[0020] The described specifications are stored in the parameter property table of the piping component assembly model. 3D callouts are drawn on the solid model of each part and are represented by arrows with text that is t...

Abstract

The invention relates to a pipeline welding line information extraction method based on a three-dimensional design model, and belongs to the technical field of digital manufacturing. The three-dimensional design model information of a pipeline assembly is directly utilized, and a welding line list and a pipeline assembly mating table are automatically extracted, so that the accuracy of welding line information is ensured; the compiling efficiency of a pipeline welding process is increased effectively; and welding of pipelines is realized.

Description

technical field [0001] The invention relates to a method for extracting pipeline weld seam information based on a three-dimensional design model, and belongs to the technical field of digital manufacturing. Background technique [0002] In the previous spacecraft development mode based on paper drawings, the drawings were used as the production basis to prepare process documents, and the weld list can only be obtained through manual identification, resulting in low efficiency and error-prone process preparation, requiring more manpower and time. Do a review. [0003] After this development mode is converted to the spacecraft digital development mode based on the 3D design model, the 3D design model of the pipeline components already contains all the information of the weld and pipeline. The spacecraft digital development model does not match. The purpose of the present invention is to overcome the problems of low efficiency, heavy workload, and poor accuracy of manually id...
