Abstract

The invention discloses a flexible-shaft transmission-type tightening device and method for internal nuts of an aero-engine, and belongs to the technical field of automated assembly. The flexible-shaft transmission-type tightening device for the internal nuts of the aero-engine comprises a tooling pre-positioning system, a nut aligning and positioning system and a flexible-shaft transmission-typetightening execution system. Through the nut aligning and positioning system, a tightening sleeve is mounted on a to-be-tightened nut in a sleeving manner and driven by a tightening motor to completethe tightening work; by the adoption of the automated operation mode, the flexible-shaft transmission-type tightening device disclosed by the invention has the characteristics of being high in degreeof automation, high in motion precision and high in tightening precision; the manual operation task is relieved; the operation process is greatly simplified; errors introduced by the manual operationare avoided; the tightening consistency of the internal nuts is guaranteed; and the whole machine assembly work efficiency is improved.

Description

technical field [0001] The patent of the invention belongs to the technical field of automatic assembly, and in particular relates to a flexible shaft-driven tightening device and method for an internal nut of an aero-engine. Background technique [0002] Aeroengine rotor casing is an important part of aeroengine, mainly composed of rotor casing and multi-stage shaft disk assembly, the end surface of the shaft disk is connected with the rear mounting surface of the rotor casing, and is fastened and connected by multiple threaded connectors uniformly distributed along the axis circumferential direction stand up. Since the aero-engine mainly works under high-temperature, high-pressure external load conditions, it places extremely high requirements on the connection between the rotor shell and the shaft disk, and the tightening quality of the threaded connection affects the assembly performance and service reliability of the whole machine. Key factor. Moreover, the distance b...
