Embodiment Construction

[0028] The following structural drawings and embodiments further illustrate the present invention.

[0029] As shown in Figure 1-6.

[0030] A method for realizing WEB-based three-dimensional assembly process files and on-site teaching, which is characterized in that it includes the following steps:

[0031] First, on the process design client, the process personnel read the geometric information and assembly information of the design model through the secondary development interface function of Pro / Engineering 3D CAD design software, store them in the assembly information database, and then import them into the virtual reality environment for The product model is assembled or disassembled, and real-time collision interference detection is performed to obtain the final assembly sequence and assembly path. The assembly path is represented by a series of discrete spatial coordinate points, and the step size can be adjusted by the user. The assembly path information is a collect...

Abstract

The invention relates to a generation method of product assembly process based on WEB and a realization method of field teaching demonstration, aiming at design problems of prior 3D assembly process. The method integrates advantages of 3D CAD software design, virtual reality technique and network application, solves problems that prior assembly process is disjoint with 3D design module, 2D paper process is not helpful for operational persons' comprehension and usage, and the generated process files are not helpful for management. The method of the invention is characterized by good convenience, vivacity and interaction, so that technicians can conveniently compile 3D assembly process files and assembly cartoons through the method and by use of browsers through Internet or Intranet, and the method can also facilitate field teaching demonstration for field assembly persons with convenience and vivacity. The method can greatly improve products assembly and design efficiency and can reduce products field assembly period.

Description

technical field [0001] The present invention relates to a method for generating a WEB-based product assembly process and a method for realizing on-site teaching, especially a method for generating and browsing a three-dimensional assembly process file, specifically a method for generating a three-dimensional assembly process file under the Internet / Intranet Implement and browse methods. Background technique [0002] Product assembly is an important link in the mechanical manufacturing process. According to statistics, in industrialized countries, about 1 / 3 of the manpower in the production process of products is engaged in related product assembly activities, 20% to 30% of the total production cost is used for product assembly, and the man-hours required for product assembly account for 10% of product production. 40% to 60% of the total working hours. Therefore, reducing the cycle of assembly process design is of great significance to improving the production efficiency of...
