This paper introduces the application of 3D design tool SolidWorks in design and highlights its role in the design of modular truck scale. I. Overview With the continuous development and improvement of truck scale products, modular electronic truck scale has gradually become the main product of electronic truck scale. In the annual sales performance, the sales of modular truck scales play an important role. As a relatively stereotyped product, the modular electronic truck scale has many commonalities in the design of the scale body, that is, the shape is similar, but the internal dimensions are not the same as the two-dimensional CAD drawing design, the scale body of each specification. It is necessary to draw separate drawings and preparation techniques. Among them, there are many repetitive drawing work, which invisibly adds workload to the design work. With the development and deepening of 3D drawing tools, its superiority has also been fully reflected. From "2D to 3D", it is becoming the development direction of deepening CAD application. With the implementation of national manufacturing information engineering, 3D CAD is The core digital design technology will become a key breakthrough to promote manufacturing technology upgrade and product development capability. In the fierce market competition, collaborative design and collaborative management are gradually being adopted by enterprises without advanced design tools, and designers cannot fully Give play to talents and design competitive products. SolidWorks is a 3D CAD mechanical design software developed by SolidWorks Corporation of the United States. Its powerful functions and easy-to-learn features have won the favor of many companies and a lot of designers, especially in many similar product designs. The role of substitution. Second, the design method and application 1. Establish a three-dimensional model of the scale body First of all, we should use SolidWorks to draw a three-dimensional model of the scale body. Since SolidWorks is a feature-based parametric solid modeling CAD software, the created 3D solid model and the size are completely related, that is to say, there is a size-driven function, that is, change. After a size, the shape of the corresponding part will change accordingly, which will bring great convenience to the design of the modular scale body without having to repaint. When building a scale body, in sketching and feature modeling, it is not necessary to input an accurate value for the size and structure of the scale body, just give a fuzzy value, but for the geometric relationship between the structures, The corresponding restrictions must be added to ensure that the mold can finally be accurately formed. Figure 1 and Figure 2 show the three-dimensional shape of the scale body. Next page
