Device allowing engine component to rotate to be assembled

Abstract

The invention belongs to the technical field of aviation engine assembly, and particularly relates to a device allowing an engine component to rotate to be assembled. The device comprises an anti-thrust bearing 2, a braking pin 3, a rotating disc 4, a compression device 5, a platform main body 6 and trundles 7. The rotating disc 4 is connected with the anti-thrust bearing 2 through the compressiondevice 5, and the rotating function of the rotating disc 4 is achieved. When the rotating disc 4 rotates to a certain angle and needs to stay reliably, the braking pin 3 is inserted into a pin hole in the edge of the rotating disc 4, and thus it is ensured that the rotating disc 4 does not rotate any longer. The platform main body 6 bears the gravity of a workpiece. An extending ring 1 is used for meeting the assembly requirements of workpieces of different diameter sizes, and rotates with the rotating disc 4 together in the working process. The trundles 7 are used for achieving the moving function of a platform, have a braking function by itself and are used for ensuring reliable braking of the platform. Unnecessary workloads of tangential displacement generated between operation personnel and assemblies are omitted, the labor intensity is relieved, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of aero-engine assembly, and in particular relates to a device capable of rotatably assembling engine parts. Background technique [0002] The status of air supremacy is increasing day by day in modern warfare, which requires fighters to perform difficult combat missions around the clock under harsh weather conditions. The aero engine is the "heart" of the aircraft and the source of aircraft power. It is known as the jewel on the top of the industrial crown. To reliably guarantee the maneuverability and combat readiness of fighter jets, aero engines with high thrust-to-weight ratio and high reliability bear the brunt. As an important link in the engine manufacturing cycle, aero-engine assembly is the post-process of engine manufacturing and an independent production stage. [0003] The aero-engine belongs to the turbine, and most of its parts are evenly distributed in the circumferential direction. Such a...

[0004] Just imagine, many people eat around a round table. The round table has a large diameter (like an engine part) and cannot be rotated. People need to walk around the table to eat, and even the most delicious dishes will be eclipsed by it.
