Untwisting wrench used for assembling guide pipe with three-way joint, and assembly method

Abstract

The invention discloses an untwisting wrench used for assembling a guide pipe with a three-way joint. The guide pipe with the three-way joint comprises the three-way joint, wherein two ports of the three-way joint are tubular ports, the other port is a thread port, and untwisting end flanges are connected to the two tubular ports of the three-way joint through pipelines. The untwisting wrench usedfor assembling the guide pipe with the three-way joint comprises an untwisting wrench head and an untwisting rod, wherein the untwisting wrench head and the untwisting rod are integrally formed; theuntwisting wrench head comprises a semicircular part and extension parts arranged at the two ends of the semicircular part, and the extension parts are parallel to the tangential direction of the endpart of the semicircular part; and the untwisting rod is a straight rod, and the untwisting rod is arranged on one side surface of the semicircular part and vertical to the extension parts. The untwisting wrench used for assembling the guide pipe with the three-way joint achieves the purpose of twisting for the guide pipe with the three-way joint, of an engine with a similar structure, and ensuresthe assembly reliability and quality for the guide pipe of the engine.

Description

technical field [0001] The invention belongs to the field of aero-engine conduit assembly, and in particular provides an anti-twist wrench and an assembly method for assembling a conduit with a three-way joint, which is mainly used when the engine is assembled with a three-way conduit, and is suitable for the field of assembly of the complete engine conduit . Background technique [0002] During the assembly process of the aero-engine, a large number of external pipelines need to be assembled. Both ends of the conduits have anti-twist hexagonal flanges, and they can be connected with two wrenches to tighten each other; but there is a special structure of the conduit, which is in the middle of the conduit There is a tee joint in the position, which needs to be connected with other pipelines, but there is no anti-twist flange. When tightening the pipe connected with the tee joint, it is easy to twist the pipe with the tee joint or cause the welding position near the joint to b...

Problems solved by technology

[0002] During the assembly process of the aero-engine, a large number of external pipelines need to be assembled. Both ends of the conduits have anti-twist hexagonal flanges, and the interconnection only needs to be tightened with two wrenches; but there is a special structure of the conduit, which is in the middle of the conduit. There is a tee joint in the position, which needs to be connected with other pipelines, but there is no anti-twist flange. When tightening the pipe connected with the tee joint, it is easy to twist the pipe with the tee joint or cause the welding position near the joint to be damaged. damage, which affects the assembly quality and reliability of the engine duct; it is necessary to use anti-twist tooling to eliminate this quality hazard
