Abstract

The invention discloses a three-dimensional assembling technology generation method and generation device, and relates to the field of three-dimensional technology design. The method comprises the steps that a component technology reference model is generated based on a product design model; a three-dimensional assembling technology model is formed; the work center to which each first assembling unit belongs is determined according to product information of all the first assembling units in the assembling technology model and work division attribute information of all the work centers in an assembling resource knowledge base; the work position to which each second assembling unit belongs is determined according to product information of all the second assembling units in the first assembling units and work division attribute information of all the work positions in the assembling resource knowledge base; and an assembling technology planning tree corresponding to the assembling technology model is established according to the work centers to which all the first assembling units belong, the work positions to which all the second assembling units belong and resource information of all the work positions in the assembling resource knowledge base. Therefore, automatic mapping and dividing of an assembling technology separation surface and construction of the three-dimensional assembling technology model can be realized.

Description

technical field

[0001] The invention relates to the field of three-dimensional process design, in particular to a method and device for generating a three-dimensional assembly process. Background technique

[0002] With the rapid development and popularization of 3D CAD software, 3D CAD system has become the basic platform for digital design and manufacturing of enterprises. However, most of the current process design is carried out on the 2D engineering drawing of parts, and the 3D model is only used as a reference. Process designers use the 2D system to complete process design based on paper 2D engineering drawings and generate paper 2D process cards, resulting in non-unique data sources and the inability to maintain correlation between process and design. At the same time, the design model does not consider the process requirements, and cannot be directly used to guide the generation of manufacturing. The expression and management of process information based on two-dimen...
