Problems solved by technology

At present, the design of the assembly process adopts the two-dimensional computer-aided process planning (CAPP) system, the utilization rate of design information is low, the compilation cycle is long, and it relies too much on the technical level and assembly experience of the craftsmen. The assembly process design process is cumbersome, and the output result is two Dimensional and tabular process documents cannot intuitively reflect the product assembly relationship, and require relatively high experience for operators, which seriously affects product quality and product assembly production efficiency

Embodiment Construction

[0007] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0008] The implementation process of the 3D assembly process design method is as follows: figure 1 shown. The specific implementation method is as follows:

[0009] 1. Import the product assembly EBOM and 3D model data into the 3D assembly process design software Teamcenter, add the sample information on the basis of EBOM and convert it into PBOM, and convert the 3D model into .jt lightweight format. In the 3D assembly process design environment, the part name, code name, quantity, material and other information corresponding to the 3D design model are extracted and associated with the lightweight model.

[0010] 2. According to the three main assembly links of section assembly, docking assembly, and test line reassembly, according to the process flow, process division, and station conditions, rearrange and divide the assembly parts on the basis of PBOM to ...

Abstract

The invention discloses a producing method for a three-dimensional craft of a final product assembly. The method comprises the following steps: introducing product EBOM and three-dimensional model (containing MDB information) into a three-dimensional assembling technical design environment; performing light weight treatment on the three-dimensional model in the technical design environment; reconstructing on the PBOM according to the links of subassembly, butt-joint and test line and the assembling level, sequence and division in each link; adding an assembling virtual part according to the requirement and lastly generating MBOM; confirming an assembling sequence and an assembling path on the MBOM; establishing processes and steps and distributing the parts in the MBOM into each process and step; establishing a three-dimensional model snapshoot and labeling for the mounting content of each assembling component; adding the information, such as, assembly equipment, technical accessory, operation demand, and finishing the editing for a technical file.

Description

technical field [0001] The invention belongs to the technical field of product assembly process informatization, and in particular relates to a method for generating a product assembly process in an MDB environment. Background technique [0002] Product assembly is the last link of product development and production, and it is also a very important link. It is one of the main factors affecting product quality, performance, development cycle and cost. With the rapid development and popularization of 3D CAD software, 3D product design is becoming more and more popular, while assembly process design is still mostly in the 2D stage. At present, the design of the assembly process adopts the two-dimensional computer-aided process planning (CAPP) system, the utilization rate of design information is low, the compilation cycle is long, and it relies too much on the technical level and assembly experience of the craftsmen. The assembly process design process is cumbersome, and the ou...
