Abstract

The invention provides a horizontal device and a method for friction-stir welding of a circular seam of a carrier rocket storage tank assembly. The device comprises a bed body, wherein a bed head and a bed tail are respectively arranged at the two ends above the bed body; a front transition ring, an outer right positioning and compressing mechanism, an outer left positioning and compressing mechanism and a rear transition ring are arranged between the bed head and the bed tail in sequence; an inner supporting mechanism and a rod system supporting mechanism are respectively hung on a bed head telescopic shaft and a bed tail telescopic shaft and can move horizontally along with the telescopic shafts; a stirring host is arranged on the bed body. The method comprises the following steps of welding a front bottom with a first cylinder section, welding a front short shell with the front bottom, welding the rest cylinder sections with the cylinder section, welding the cylinder sections and a rear bottom, and welding a rear short shell and a rear bottom. According to the horizontal device and the method, one-time clamping, in-situ edge milling and welding of the storage tank can be realized; the assembling precision and the welding efficiency are greatly improved; high-precision and high-efficiency welding of a rocket storage tank can be realized; the effect is good.

Description

technical field [0001] The invention relates to the technical field of aerospace equipment welding, in particular to a horizontal device and method for friction stir welding of a carrier rocket tank general assembly circular seam. Background technique [0002] Friction stir welding technology has become a very ideal welding method for aluminum alloy tank welding in the aerospace field due to its many technical advantages such as high joint quality, less defects, and small deformation. The thruster tank is composed of a front short shell, a front bottom, multi-section barrel sections, a rear bottom, and a rear short shell welded in sequence. At present, there is no complete set of friction stir welding equipment for horizontal tank girth seam in my country. Contents of the invention [0003] The object of the present invention is to provide a horizontal device and method for friction stir welding of the circular seam of the general assembly of the launch vehicle tank, whic...
