摘要
针对大型复合材料机身壁板需要调姿定位和无损夹持的问题,提出基于混联调姿和真空吸附的柔性工装结构方案。在对复合材料壁板调姿定位工艺流程和真空吸附工艺流程分析基础上,设计一种集成了串联式的X向和Y向十字滑台、并联式的Z向和B角调整模块、真空吸附和A角自适应调节的柔性工装结构,并通过柔性工装试验件进行了功能试验。试验结果表明:调姿定位和真空吸附柔性工装调姿平稳、定位准确、真空吸附安全可靠,满足调姿定位和无损夹持功能要求。
In order to solve the problem of the positioning and nondestructive holding of the fuselage panel of the large composite material, the paper puts forward the flexible tooling structure scheme based on mixed joint positioning and vacuum adsorption. On the basis of the analysis of the position process and the vacuum adsorption process of composite materials panel, design a kind of integrated X axis and Y axis tandem cross sliding table, parallel connection of Zaxis and B angle adjustment module, vacuum adsorption and A angle adaptive flexible tooling structure. And the function test results of flexible tooling test pieces show that the positioning and adsorption of the flexible tooling are stable and accurate, and the adsorption is safe and reliable, which satisfy the requirements of positioning and nondestructive clamping function.
