Abstract

The invention discloses an aero-engine internal nut universal joint driven tightening device and method and belongs to the technical field of automatic assembly. The aero-engine internal nut universaljoint driven tightening device comprises a tool pre-locating system, a nut alignment locating system and a universal joint tightening system. A nut to be tightened is sleeved with a tightening sleevethrough the nut alignment locating system. A tightening motor drives the tightening sleeve to complete tightening operation. The aero-engine internal nut universal joint driven tightening device adopts the automatic operation mode to implement the steps of coaxially locating the tightening device and a rotor shell, rotating the tightening sleeve to the nut to be tightened, tightening the nut andthe like, has the characteristics of being high in automation degree, motion precision and tightening precision, reduces manual operation tasks, greatly simplifies the operation process, avoids errorscaused by manual operation and ensures the tightening consistency of the internal nut, and the working efficiency of whole machine assembling is improved.

Description

technical field [0001] The patent of the present invention belongs to the technical field of automatic assembly, and in particular relates to a universal joint transmission type 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. More...
