Disassembling device for centrifugal ventilation impeller assembly of aero-engine

The invention discloses a disassembling device for a centrifugal ventilation impeller assembly of an aero-engine. The disassembling device comprises a base, a sleeve clamping jaw and a core rod. A receding groove is formed in the base, a vertically-arranged gear shaft supporting column is fixed in the receding groove, a plurality of pin supporting rods are detachably arranged on the top of the base, and the pin supporting rods are vertically arranged on the base. The sleeve clamping jaw is composed of a sleeve and a plurality of clamping jaws, and the multiple clamping jaws are connected into the sleeve in a threaded mode and can be unfolded or folded relative to the axial center line of the sleeve through relative rotation between the clamping jaws and the sleeve. The core rod penetrates through the sleeve and is right opposite to the center of the base, and clamping teeth are arranged at the end of the core rod. According to the invention, each connection point of the ventilation impeller assembly can be st
