Abstract

The invention discloses a fixture capable of realizing rapid and accurate assembly of a high-pressure combined rotor of an aero-engine, comprising: a base, a bearing seat, a mandrel, a front axle seat and a dial. The bearing seat is arranged on the base, the mandrel is fitted in the bearing seat and is slidingly fitted with the bearing seat, the front axle seat is arranged above the bearing seat and the mandrel, The dial is installed above the front axle seat. The invention can realize rapid and accurate assembly of the high-pressure combined rotor of the aero-engine, shorten the assembly period, improve the assembly accuracy and efficiency, and thus effectively guarantee the assembly quality of the high-pressure combined rotor of the aero-engine.

Description

technical field [0001] The invention belongs to the technical field of aero-engine rotor assembly, and relates to a fixture capable of realizing rapid and precise assembly of a high-pressure combined rotor of an aero-engine. Background technique [0002] The aero-engine rotor assembly is composed of a high-pressure compressor disc, a high-pressure turbine disc, front and rear journals, etc. Each part is positioned through a joint (cylindrical surface and end surface), and then a set of high-strength precision bolts are used to form a whole. rotor. However, if the initial axial pre-tightening force of the bolt is too large or too small, it is easy to cause failure, which is directly related to the safety of the rotor during operation, which in turn affects the performance of the entire engine and the stability and safety of its work. Therefore, due to its particularity, the aero-engine rotor has a large number of bolts, and the installation quality requirements for each bolt...
