Abstract

The invention provides a spherical top cover assembly tailor-welding method and device. The tailor-welding method comprises the four steps. The tailor-welding device comprises a base, a positioning base, an annular body, an upper presser structure, an internal supporting structure, an outer supporting structure capable of positioning the outer wall of a spherical top cover, a press plate assemblycapable of tightly pressing the upper end face of a connection flange, and a first press ring capable of positioning a tunnel connection flange. The spherical top cover assembly tailor-welding methodand device solves the technical problems that because the structure of the spherical top cover is specific, the assembly and welding difficulty between parts is high, and welding methods in the priorart are not suitable for assembly welding.

Description

technical field [0001] The invention belongs to the technical field of rocket storage tanks, and in particular relates to a method and device for tailoring welding of spherical top cover components. Background technique [0002] The tank bottom of active rockets generally adopts a spherical bottom or an ellipsoidal bottom structure, which is composed of a top cover, a ring and a transition ring by tailor-welding, and the top cover structure is a single sheet metal forming part. In the development of fuel storage tanks for the new generation of manned launch vehicles in my country, a cone-bottom structure with a diameter of 5 meters was adopted for the first time. Among them, the spherical top cover assembly is a special-shaped structure, which is a brand-new structural form, which is made up of a spinning-formed spherical top cover in the middle and connecting flanges at both ends. Due to the special structure of the spherical top cover, As a result, it is difficult to asse...
