Parameterization design method of three-dimensional guide pipe welding clamp

Abstract

The invention relates to a parameterization design method of a three-dimensional guide pipe welding clamp. The parameterization design method specifically comprises the steps: step 1, starting a toolmodule containing a standard part family; step 2, selecting a typical part tool module to establish a mother set unit module tool; step 3, selecting a mother set unit module tool schematic diagram anda parameterized model file, and determining main parameters; step 4, modifying main parameters; and step 5, automatically updating the model to generate a new tool clamp drawing. According to the method, the three-dimensional model can be controlled through the main characteristic parameters, automatic updating and modification of the three-dimensional model and the two-dimensional drawing can beachieved, real-time updating can be achieved, a convenient and rapid tool design tool is provided for tool designers, the software operation time of the designers is shortened, and the welding clampdesign efficiency of the guide pipe series pieces is improved.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional fixture design, and in particular relates to a parametric design method of a three-dimensional conduit welding fixture. Background technique [0002] Tooling and fixture design is an important link in the process preparation of the manufacturing industry. It is the link between product design and workshop production. With the development of 3D technology, the tooling design model has gradually changed from 2D design to 3D design. In practical applications, replacing two-dimensional graphics with three-dimensional graphics runs through the entire fixture design and manufacturing process, and it has become a fact to realize production without drawings. [0003] Compared with 2D tooling design, 3D tooling design is more complex and precise. Only for the fixture design of a single batch of parts, the 3D tooling design is carried out one by one, so the design cost is high and the efficiency i...

[0003] Compared with 2D tooling design, 3D tooling design is more complex and precise. Only for the fixture design of a single batch of parts, the 3D tooling design is carried out one by one, so the design cost is high and the efficiency is low. At present, the 3D tooling design of serial parts mainly Relying on tooling designers to manually clone similar tooling, and then modifying the model or remodeling, failed to take full advantage of the advantages of high similarity of catheter series models, model modification methods are more random, not systematic and standardized enough
