Engine air bleed mechanism assembling method based on pushing jacking tool and pushing jacking tool

Abstract

The invention discloses an engine air bleed mechanism assembling method based on a pushing jacking tool and the pushing jacking tool. An air bleed valve driving rod rocker arm and a air bleed valve driven rod rocker arm are adjusted, so that an air bleed valve and an air bleed main pipe are in a completely closed state; at the moment, a push rod, close to the position of the air bleed valve driving rod rocker arm and the position of the air bleed valve driven rod rocker arm, of the pushing jacking tool is rotated, thus, the air bleed valve driving rod rocker arm and the air bleed valve drivenrod rocker arm are tightly jacked by a pressing block and kept still; and the air bleed valve driving rod rocker arm and the air bleed valve driven rod rocker arm are connected through a multi-connecting-rod assembly, a first connecting rod of the multi-connecting-rod assembly is connected with the air bleed valve driving rod rocker arm at first, finally the length of the last connecting rod of the multi-connecting-rod assembly is adjusted, the last connecting rod of the multi-connecting-rod assembly is connected with the air bleed valve driven rod rocker arm, and assembling of an engine air bleed mechanism is completed. Through the engine air bleed mechanism assembling method based on pushing jacking tool and the pushing jacking tool, the assembly quality can be improved, and the failurerate of breakage of the air bleed valve driving rod or the air bleed valve driven rod is reduced.

Description

technical field [0001] The invention belongs to the field of assembly technology, and in particular relates to an assembly method of an engine deflation mechanism based on a push-up top tool and a push-up top tool. Background technique [0002] Both the active lever of the bleed valve and the follower lever of the bleed valve belong to the control lever of the bleed valve, and are the main components of the bleed mechanism of a certain type of engine. Specifically, there are four control rods for the deflation valve, one is the active rod of the deflation valve, the other is the follower rod of the deflation valve, and the other two are support rods, wherein the active rod of the deflation valve and the follower rod of the deflation valve Right on set. They are all installed in the outer casing of the intermediate casing, the inner end is fixed on the intermediate casing separation ring with a bracket, the outer end is fixed on the installation boss of the intermediate casi...

AI Technical Summary

Problems solved by technology

[0004] Since the bleed valve and the bleed main pipe are assembled outside the casing of the high-pressure compressor and inside the culvert casing, the rocker arm of the active lever of the bleed valve and the rocker arm of the follower lever of the bleed valve are used to adjust the bleed valve to the fully closed position. They are respectively located on the left and right sides of the engine outside near the horizontal position. In the prior art, the active rod rocker arm of the deflation valve and the follower rod rocker arm of the deflation valve are artificially supported so that the deflation valve is in a completely closed position, that is, the deflation valve is guaranteed to be in a completely closed position. The fitting surface of the exhaust main pipe is closely fitted in the circumferential direction, which is inconvenient to operate, and it is easy to cause unreliable assembly due to personnel fatigue, work negligence, or inconsistent coordination and cooperation during the assembly process.
