The invention discloses an elastic locking device for
turbofan engine rotor disassembling, and belongs to the field of large
turbofan engine compressor assembling. The device comprises a rotary
handle, a supporting rod, a plurality of elastic locking components and a plurality of
extrusion components, wherein the rotary
handle is provided with a threaded hole, the first end of the supporting rod is provided with an external thread matched with the threaded hole, the supporting rod is sleeved with a spacing bush, and the first end of the spacing bush is close to the rotary
handle; and the supporting rod is sleeved with the elastic locking components, the elastic locking components are sequentially arranged at intervals in the direction from the second end of the supporting rod to the firstend of the supporting rod to form elastic locking units, the
tail ends of the elastic locking units abut against the
tail end of the spacing bush, and the
extrusion components are further arranged between the elastic locking units and the supporting rod in a sleeved mode and are sequentially and tightly connected. According to the device, the disassembling and assembling efficiency of an engine rotor can be effectively improved, the risk that parts, especially blades, are scratched due to collision is reduced, and the device is easy to operate, safe and effective.
