用于航空发动机混合器波瓣组件自动氩弧焊工装夹具的设计

Design of automatic argon arc welding fixture for mixer lobe components in aircraft engine

  • 摘要: 航空发动机混合器波瓣组件成品是由若干个曲面件(薄板钛合金特种冲压件)拼焊而成,因其复杂、无规律的曲面形状,使其难组装,焊接质量难保证,焊接变形难控制。针对以上问题和难点,该文作者所属的3个公司携手共同研制了用于航空发动机混合器波瓣组件自动氩弧焊的工装夹具,主要介绍混合器波瓣组件自动氩弧焊的工装夹具所属系统组成和工装夹具的结构组成和特点,及其组装焊接过程中的工作原理和操作过程。结果表明,该工装夹具能一次连续组装若干个单件;该工装夹具能有效地控制焊接过程的变形;焊后波瓣成品尺寸及外表质量符合工艺要求,能够实现批量生产。

     

    Abstract: The finished product of mixer lobe components in aircraft engine was composed of several surface parts(sheet titanium alloy special stamping parts) by blank welding. Due to its complex and irregular curved shape, it was difficult to assemble, guarantee welding quality and control welding deformation. To solve the above problems and difficulties, The authors’ three companies in the paper developed a automatic argon arc welding fixture for mixer lobe components in aircraft engine, hand in hand together. The system composition, the structure and characteristics of the automatic argon arc welding fixture for mixer lobe components were introduced together with its working principle and operation process in the process of assembly welding. The results showed that the fixture could be used to assemble several single pieces continuously at one time. The fixture could effectively control the deformation of welding process. After welding, the size and surface quality of the finished product met the technical requirements, and could achieve mass production.
