Abstract

The invention discloses an assembly device and an operation method for connecting a nut in a narrow space of a high-pressure rotor of an engine. The positioning mechanism, the auxiliary positioning seat, the taking-out mechanism and the rotor assembly are simulated to assemble the torque measurement mechanism; the trajectory folding torque input mechanism is assembled on the angular indexing mechanism and connected with the electric wrench, and the angular indexing mechanism is connected to the On the upper end surface of the positioning and pressing mechanism, the lifting and positioning mechanism is vertically connected to the upper end surface of the angular indexing mechanism; the device has reliable structure, convenient operation, good performance, and can effectively meet the assembly operation of the connecting nut in a small space. While greatly improving the assembly efficiency, the output torque can also be precisely controlled, reducing the labor intensity of the 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. ...
