Abstract

The invention discloses an engine high-pressure rotor narrow and small space connecting nut assembly device and an operation method. The engine high-pressure rotor narrow and small space connecting nut assembly device comprises a locating and pressing mechanism, an angular indexing mechanism, a lifting and locating mechanism, a track folding torque input mechanism, a nut and turbine shaft end tooth initial angular locating mechanism, an auxiliary locating seat placing and taking mechanism and a rotor assembly simulation assembly torque measurement mechanism. The track folding torque input mechanism is assembled on the angular indexing mechanism and is matched and connected with an electric wrench. The angular indexing mechanism is matched and connected with the upper end face of the locating and pressing mechanism. The lifting and locating mechanism is perpendicularly connected to the upper end face of the angular indexing mechanism. The engine high-pressure rotor narrow and small space connecting nut assembly device is reliable in structure, convenient to operate and good in usability, can effectively meet the requirements for assembly operation of connecting nuts in a narrow andsmall space, can also accurately control the output torque while greatly improving the assembly efficiency and reduces the labor intensity of an operator.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to an assembly device for connecting nuts in a narrow space of an aero-engine high-pressure rotor. Background technique [0002] At present, the structural design of domestic large-scale aero-engines is in line with that of American (GE, RR) engines, and each component is modularized. The compressor rotor and turbine rotor are assembled by components, and the joints are positioned by cylindrical seams, and the inner cavity is fastened with D-type anti-rotation bolts and self-locking nuts. Due to the small diameter of the rear journal of the turbine rotor, the diameter of the connecting bolt is large, the depth of the nut installation position from the end face of the turbine rear journal is large, the nut requires a large tightening torque, and the maximum torque for disassembly is twice the tightening torque, resulting in the placement of the nut. Tightening is difficult. ...
