Aircraft panel assembly mainly includes the pre-joining process and the riveting process. In addition, the traditional pre-joining process is mainly executed by bolts, which has problems such as the large tightening torque, inconvenient bilateral tightening, heavy workload, and inconvenient loading and unloading. To solve the above-mentioned problems, a research of new temporary fastener is performed deeply from three levels of quick installation, labor-saving, and reversible ability. This involves (a) employing the lever mechanism and the rapid expansion anchor to implement the rapid clamping and disassembly of working processes by labor-saving; (b) integrating the adjusting spring to overcome the tolerances of parts; and (c) building up the space-cross slide rails to provide the axial clamping forces and the reversible forces. The application of designed fasteners was employed into the production of aircraft panel, and the error between theoretical and experimental values was less than 10%. Besides this, the result showed the good effect in panel clamping and the reliable processes of loading and unloading installation, and will greatly reduce the complexity of pre-joining process, the difficulty of installation, and the comprehensive cost.

一种省力可逆的快速临时扣件的设计

飞机面板组装主要包括预接合工序和铆接工序。此外，传统的预接合工艺主要是通过螺栓来完成，存在拧紧扭矩大、双边拧紧不方便、工作量大、装卸不方便等问题。针对上述问题，从安装快捷、省力、可逆性三个层面对新型临时扣件进行了深入研究。这包括（a）采用杠杆机构和快速膨胀锚固件，以省力的方式实现工作过程的快速夹紧和拆卸；(b) 整合调整弹簧以克服零件的公差；(c) 建立空间交叉滑轨以提供轴向夹持力和可逆力。设计紧固件应用于飞机面板生产，理论值与实验值误差小于10%。此外，该结果还表明，在面板夹紧方面效果良好，装卸安装过程可靠，将大大降低预连接过程的复杂性、安装难度和综合成本。
