Description

Bolt fuse binding tool for aircraft assembly Technical Field The invention relates to the technical field of aircraft assembly, in particular to a bolt fuse binding tool for aircraft assembly. Background After the bolts are adopted to fasten and connect the mechanical equipment, the bolts are required to be pricked to realize anti-loose fixing, namely, adjacent bolts are twisted in series through the fuse penetrating through the fuse holes of the bolts, and the bolts are prevented from loosening by utilizing the mechanical restraint effect of the fuse, so that the mechanical equipment is ensured to safely run in the working environment of high-frequency vibration. However, because the mechanical equipment of the aircraft is narrow in internal structure and has more closed angle areas, the operation space is insufficient, the traditional tool cannot directly go deep into the operation space to perform the fuse tying operation, and a large amount of peripheral parts must be disassembled first, so that enough operation space is reserved to perform the fuse tying operation. Therefore, the conventional fuse bundling work is time-consuming and labor-consuming, increases the assembly time and labor cost, and is also likely to damage parts due to disassembly operation, thereby affecting the assembly precision and the overall quality of mechanical equipment, and meanwhile, the disassembled reinstallation procedure can further prolong the production period, reduce the production efficiency and be difficult to meet the requirements of efficient and accurate aircraft assembly operation. The Chinese patent document with the authorized bulletin number of CN213323880U discloses an iron wire bundling device which comprises a shell and a wire tightening plate, wherein the wire tightening plate is provided with a plurality of threading holes, a supporting plate is fixedly connected between inner surface walls at two sides of the inside of the shell, a driving motor is arranged on the inner surface wall at the top of the shell, an output shaft of the driving motor penetrates through the supporting plate and is connected with a transmission shaft in a transmission way, and the free end of the transmission shaft is connected with the wire tightening plate. According to the technical scheme, the transmission shaft is driven by the driving motor to rotate so as to drive the wire tightening plate to rotate, and the automatic tying of the iron wires is realized by twisting the iron wires, but the supporting plate and the wire tightening plate are arranged in the shell, and the whole structure is not suitable for tying work in a narrow space. Disclosure of Invention The invention aims to solve the technical problem of providing a bolt fuse tying tool for aircraft assembly, which can be conveniently operated in a narrow space and a closed angle area. The technical scheme includes that the bolt fuse binding tool for aircraft assembly comprises a driving part, a flexible transmission assembly and a fuse clamping assembly, wherein the flexible transmission assembly comprises a flexible hose and a rotating mandrel rotatably arranged in the flexible hose, one end of the rotating mandrel is in transmission connection with the driving part, the other end of the rotating mandrel is fixedly connected with the fuse clamping assembly, the driving part drives the rotating mandrel to rotate so as to drive the fuse clamping assembly to rotate, and the fuse clamping assembly comprises a fuse clamping part. The flexible transmission assembly can realize bending at any angle, so that the power of the driving part can be transmitted to the fuse clamping assembly in a narrow area and a closed angle area, and the problem of power transmission blockage caused by space limitation in aircraft assembly work is solved. The fuse clamping assembly is characterized by further comprising a connecting part, one end of the connecting part is fixedly connected with the rotating mandrel of the flexible transmission assembly, the other end of the connecting part is movably connected with the fuse clamping part, the fuse clamping part comprises two clamp bodies which are movably connected to the connecting part, and the two clamp bodies are arranged at intervals and are connected through an adjusting bolt. According to the invention, through the cooperation of the clamp body and the adjusting bolt, the fuse is clamped conveniently, and the clamping distance and the clamping force of the fuse clamping assembly can be adjusted, so that the clamping requirements of fuses with different specifications are met. As an improvement of the scheme, elastic pads are fixedly arranged on the opposite surfaces of the two clamp bodies, and the opposite surfaces of the two elastic pads are anti-slip surfaces. According to the invention, the elastic pads are arranged on the opposite surfaces of the clamp body, so that the fuse clamping part and the fuse form a better bonding relations
