Abstract

The invention discloses a machining method for double oil pipes of a controllable-pitch propeller, and belongs to the technical field of controllable-pitch propeller part machining. The strength and the deformation resistance of the cylindrical inner joint blank and the cylindrical outer joint blank which are not provided with the supporting threaded holes are good, and deformation can be reduced. The inner pipe body and the barrel-shaped inner connector blank are welded to form a first pipe system structure, then the outer pipe body is welded, the barrel-shaped outer connector blank and the double-pipe-body connector form a second pipe system structure, and connection, installation and machining are convenient. A first threaded groove, a supporting threaded hole and a second threaded groove are machined in the cylindrical outer joint blank, the outer peripheral wall of the outer pipe body and the cylindrical inner joint blank respectively, and the relative positions are guaranteed. And finally, the first pipe system structure and the second pipe system structure are welded. And the controllable-pitch propeller double oil pipes with better quality are obtained. And the scrapping possibility is reduced, and the yield of the double oil pipes of the controllable-pitch propeller is improved.
