Abstract

The invention relates to a large-diameter rotor assembling tool assembly and a using method thereof. The large-diameter rotor assembling tool assembly comprises a hollow sleeve provided with an external thread and a rotating disc arranged in a steering wheel shape. The bottom of the hollow sleeve is in thread connection with the top of a rotor assembling hole. The rotating disc is in thread connection with the top of the hollow sleeve and used for lifting and pressing the hollow sleeve and a rotor, so that the rotor and an impeller shaft are convenient to assemble. By means of cooperation of the rotating disc in the steering wheel shape and the hollow sleeve, the rotator can be lifted or pressed conveniently, the situation that when the rotor is assembled, due to the narrow space, assembling is inconvenient and direct contact with the rotor is needed is avoided, and fast assembling can be carried out conveniently.

Description

technical field [0001] The invention relates to the technical field of rotor assembly tooling, in particular to a large-diameter rotor assembly tooling assembly and a method for using the same. Background technique [0002] In the field of aero-engine technology, aero-engine assembly is the last link in the aero-engine manufacturing process, and it is also one of the most important manufacturing links. Under the conditions of the existing aero-engine design scheme and processing technology level, the quality of assembly and work efficiency have an important impact on the quality, performance and production efficiency of the engine. Therefore, in the assembly process, the coaxiality of the installed rotor should be improved as much as possible, so as to reduce the vibration of the aero-engine and improve the performance of the aero-engine. [0003] However, in actual production, the assembly of aero-engines is completely manual assembly. The level of assembly accuracy and st...
