Airplane composite material bolt hole lining flanging device

The utility model provides an aircraft composite material bolt hole lining flanging device, and belongs to the technical field of aviation flanging devices. The device comprises a support, a punching pin, a hand pressing handle, a punch, a 120-degree conical head, a punch turntable and a compression spring. The airplane composite material bolt hole lining is assembled on the 120-degree conical head, the 90-degree punch, the 120-degree punch and the 180-degree punch are used for aligning and concentric, punching and flanging are sequentially rotated, 180-degree punching and flanging can be achieved through one-time assembly, and the process use requirement is met. The device is simple and practical in structure, has high practicability compared with the prior art that corresponding wrenches and tools are selected manually, can improve the one-time success rate of flanging of the composite material bolt hole lining of the airplane, and reduces the scrap probability of the composite material bolt hole lining cau
