针对国内航空制造业在长桁工件切边中使用的装夹夹具专业性强、定位精度低、经济性不高、不适用现代化航空制造的需求,设计了一种飞机长桁零件切边的柔性夹具。运用CATIA V5R20对柔性夹具进行建模、装配,并应用DELMIA的PDM模块对夹具夹持工件的运动过程进行模拟仿真,检查干涉并优化结构。最终设计出满足要求的柔性夹具。 For the domestic aviation manufacturing industry, the clamping fixture used in the trimming of long-truss workpieces is highly specialized, has low positioning accuracy, low economic efficiency and is not suitable for the needs of modern aviation manufacturing. The trimming flexibility of the aircraft long-truss parts is designed Fixture. CATIA V5R20 is used to model and assemble the flexible fixture. The module of DELMIA is used to simulate the movement process of the fixture and to check the interference and optimize the structure. The final design to meet the requirements of the flexible fixture.
