Three-dimensional data model rapid assembly method, system and device and storage medium

Abstract

The invention discloses a three-dimensional data model rapid assembly method, system and device and a storage medium, and the method comprises the steps: selecting a secondary development command of astandard part needing to be inserted, so as to display a corresponding parameter window on a CATIA software interface; after the parameters of the standard component are input into the parameter window, obtaining the geometrical characteristics of the target assembly; obtaining an object model in combination with the geometrical characteristics and the input parameters, obtaining a path where a file corresponding to the standard component is located according to the object model, and inserting a three-dimensional data model of the standard component into CATIA software; and moving the three-dimensional data model of the standard component to the position of the target assembly according to the spatial position coordinate relationship between the target assembly and the standard component.According to the method, the model of the inserted standard part is automatically measured and judged, the path where the corresponding part model file is located is automatically searched, the stepsof manual measurement and judgment are greatly reduced, the assembly speed and accuracy are greatly improved, and the method can be widely applied to the field of mechanical design and the field of computers.

Description

technical field [0001] The invention relates to the field of mechanical design and computer field, in particular to a method, system, device and storage medium for rapid assembly of three-dimensional data models. Background technique [0002] At present, CATIA, the 3D design software owned by Dassault, has become the mainstream 3D design software in the fields of automobile equipment, aircraft manufacturing, and traditional machinery. With the expansion of market demand, the amount of data designed by designers using CATIA is increasing day by day. Usually, when designers use CATIA for 3D design, they need to assemble a large number of standard fasteners such as screws, gaskets, pins, and pressure blocks for the equipment, so that the 3D data model can be as close as possible to the real equipment state and satisfy customers. Requirements and standards for 3D data models. Taking the design of tooling and fixtures in the non-standard design field as an example, the average n...

Problems solved by technology

[0003] In order to speed up the assembly of standard parts and fasteners, there are currently two mainstream methods. The first method uses the capture command that comes with CATIA. The main disadvantage of this method is: if the target to be assembled is in the three-dimensional space If the position in the center is special, or the assembly relationship between the target to be assembled and the assembly part has special requirements (for example, the assembly features form a certain angle), using this function will greatly increase the step-by-step fitting steps in the middle, or even make it completely i
