Three-dimensional software-based weldment modeling method

Abstract

The present invention provides a three-dimensional software-based weldment modeling method, and belongs to the field of welding modeling. The method comprises: step 1, drawing the finished weldment ina three-dimensional software into a part; step 2, establishing a segmentation plane, using a segmentation method to segment the entire part into spliced parts of different sizes, and carrying out chamfering on the connection of each spliced part; step 3, saving the parts completed in the step 2 as a file in an editable universal form that can be opened by multiple three-dimensional software; andstep 4, re-opening the file generated in the step 3 by using the 3D software to generate multiple features, wherein each feature corresponds to an independent spliced part in the step 2, and each feature is saved as a separate part illustration. According to the method provided by the present invention, the design time can be saved, the work efficiency can be improved, and the accuracy of the sizeof each dismantled welding part can be ensured to be 100%.

Description

technical field [0001] The invention belongs to the field of weldment modeling and relates to a welding modeling method based on three-dimensional software. Background technique [0002] Most of the large-diameter slurry shield machines are now in the form of normal pressure tool change. According to the process requirements, the cutter body should be designed as a box-shaped beam with a hollow structure. The connection between the spoke and the base is mostly an intersecting structure. If you follow the traditional design method, use 3D software to model each part, and then assemble it, because each part has many intersecting lines, which are not on the same plane In fact, many 3D sketches or auxiliary datum planes need to be established during the drawing process, which requires relatively high modeling ability of the designer, and many spatial curves cannot be drawn accurately, which leads to very low work efficiency and very low It is difficult to ensure the correct siz...
