Research on the Application of Flexible Modular Fixtures in the Machining of Welded Assemblies

摘要: 焊接组件在氩弧焊过程中不可避免会发生变形，影响产品对外连接尺寸的质量。本文通过对产品结构及接口尺寸进行分析，改进现有加工工艺方法，结合理论计算结果设计专用柔性组合夹具，确保焊接后产品装夹定位的准确性、稳定性。研究结果表明：柔性组合夹具可以有效固定异形焊接组件，为外连接尺寸调整到焊接后加工做支撑，规避外连接尺寸在焊接过程中的变形问题，提高产品合格率。

Abstract: Deformation is inevitable during the argon arc welding of welded assemblies, which compromises the dimensional quality of external connections. By analyzing the product structure and interface dimensions, this paper proposes an improved machining process and designs a specialized flexible modular fixture based on theoretical calculations to ensure the accuracy and stability of clamping and positioning after welding. The results demonstrate that the flexible modular fixture effectively secures irregularly shaped welded assemblies, thereby supporting the adjustment of external connection dimensions to post-weld machining. This approach successfully mitigates deformation issues of external connection dimensions during welding and significantly improves product qualification rates.
