基于Pro/M的组合夹具结构分析

Structural analysis of modular fixture based on Pro/M

组合夹具作为一种先进的柔性工艺装备,特别适用于数控机床、加工中心等先进制造单元,是今后夹具技术发展的一个重要方向。组合夹具由一整套标准元件组装而成,用有限元法计算其在切削力和夹紧力作用下的应力应变,以模拟夹具在实际加工过程中的变形,提高夹具设计水平。Pro/Mechanica是Pro/ENGINEER的一个有限元分析模块,可以实现与三维CAD软件Pro/E的无缝集成,能有效提高装配体有限元分析的效率。因此,基于Pro/Mechanica进行组合夹具结构分析,可及时发现设计缺陷,缩短夹具研制周期,提高效率。

As an advanced flexible assembly fixture, Modular fixture is especially apply to advanced machine tool, such as NC machine tools and CNC machine center. Modular fixture is an important developing direction of the future Fixture technology. Every Modular Fixture is made up of a whole set of standard component. Calculating its stress and strain under cutting force and clamp force by finite element method, in order to simulate the fixture＇s deformation in the course of actual working, and can improve the design level of fixture. Pro/Mechanica is a finite element analysis （FEA） module of Pro/ENGINEER. It can seamlessly connect to Pro/ENGINEER, which is three-D CAD software. At the same time, Pro/Mechanica can effectively improve the efficiency of Assembly analysis. So, structural analysis of modular fixture based on Pro/M can help designer find the defect of design in time, reduce the time of fixture design and increased efficiency.
