Abstract
The invention discloses a blind cavity structure interference assembly rotor cold assembly elastic guide device for assembly. The blind cavity structure interference assembly rotor cold assembly elastic guide device is characterized in that a guide shaft is a main body structure part and is of a cavity tubular structure, the right end of the guide shaft is of a large diameter and is provided witha step, the large diameter of the guide shaft is matched with the inner control large diameter of the shaft end of a low-pressure turbine, three radial fixing holes are formed in the guide shaft, a stop pin is welded to the edge of each hole, and the left end is of a conical guide structure. According to the invention, a screw rod is screwed inwards through a handle, a large compression spring iscompressed by pressing a core shaft to move towards the inner side, and the core shaft is separated from a stop pin when moving inwards in a rotating mode and retracts inwards into a radial fixing hole in the large end of a guide shaft under the elastic action of a compression spring, after a guide device is assembled to a wall groove in the end of a low-pressure turbine shaft, the screw rod is screwed out outwards through the handle, the stop pin moves outwards to extend out of the outer diameter surface of the large end of a guide pin shaft till the outer diameter surface is fixedly clamped,a low-pressure turbine rotor is assembled, the handle is assembled into a screw rod hole after assembly, and then the screw rod is screwed into and separated from the guide device inwards through thehandle.
