Abstract

The invention discloses a method for automatically generating a digifax duct welding fixture intelligent system, mainly comprising the following steps: large ORACLE database software is used for managing engineering data; COM components are used on a platform of CATIAV5R16 and the developing environment and an interface provided by VC6.0++ and CATIA are used for developing systematic modules for engineering management, fixture design, duct design, designing tools, two-dimensional engineering drawing, database management, and the like to create a virtually assembled three-dimensional welding fixture. According to the welding characteristics of part ducts of products, auxiliary fuel tanks, and the like, the method utilizes techniques of three-dimensional digital digifax, visible space digital virtual assembly, fixture rigidity calculation, interference simulation of loading space for welding parts, fixture structure analysis, and the like to improve the efficiency and the quality for the welding fixture design and weak links of frock digital design. Compared with conventional CATIA design, the efficiency is improved by about 60 percent, the design quality of the welding frock can be greatly improved simultaneously, and the repair rate of the welding frock is reduced by about 70 percent.

Description

Technical field [0001] The invention relates to a software based on CATIA, which can realize the automation of the design process of a pipe welding fixture and a method for automatically generating a digital-analog pipe welding fixture intelligent system. It can be considered that this method can also be extended to the auxiliary design of fuel tank welding fixture, sheet metal welding fixture design, and catheter mandrel. Background technique [0002] In the aviation manufacturing, the number and variety of welding tooling for catheters can be described as large, and the update speed of catheter products is accelerating, which requires a shorter design and manufacturing cycle for tooling. At present, our complete set of fixtures is composed of three parts: locator, clamping mechanism and clamping concrete. In welding operations, complex fixtures with a number of different clamping mechanisms and positioners mounted on the clamp body are often used. Among them, except that the cl...
