Heating device of fuel gas generator rotor for aero-engine and assembly method

The invention discloses a heating device of a fuel gas generator rotor for an aero-engine and an assembling method.The heating device comprises a rotor hoisting mechanism and a coil heating mechanism, the rotor hoisting mechanism is located over the coil heating mechanism, and the coil heating mechanism comprises a workbench, a coil radius adjusting assembly and a coil height adjusting assembly; the problems that the assembly quality of a gas generator rotor is poor, and rotor balance is not qualified easily are solved, original overall heating of the gas turbine rotor is changed into local heating through process improvement, the heating efficiency of the gas turbine rotor is greatly improved, the production cost is reduced, the production efficiency is improved, and the production cost is reduced. The assembly quality of the engine is guaranteed, the vibration fault occurrence rate of the aero-engine is reduced, the reliability of the aero-engine is greatly improved, meanwhile, the rotor neck heating device
