The invention belongs to the technical field of aeronautical manufacturing part processes, and discloses a device and a method for splicing and expanding an airplane cup base. A mechanical expansion structure is adopted, the mandrel drives the sliding block, the shouldered nut is tightened, the expansion core is expanded, the parts are fastened after being bonded, the parts are rapidly disassembled after bonding fastening is kept and the shouldered nut is loosened, and the purpose of bonding and expanding of the airplane cup base parts is achieved through the bonding and expansion device and method. By means of the device and the method, bonding and expanding of the parts are achieved. The device is easy to operate, and the production efficiency and the bonding quality are improved. 本发明属于航空制造零件工艺技术领域，本发明公开了一种用于飞机杯座粘接胀紧装置及方法；其采用机械式胀紧结构，由芯轴带动滑块，拧紧带肩螺母，使胀芯胀开，实现零件粘接后的紧固，粘接紧固保持之后，松掉带肩螺母之后，实现零件的快速拆卸，通过粘接胀紧装置及方法达到飞机杯座零件的粘接胀紧目的。通过本发明的装置及方法，实现零件的粘接胀紧。本装置操作简单，提高生产效率和粘接质量。
