Circumferential seam welding support device for arrow body barrel section of launch vehicle

Abstract

The invention relates to rocket body manufacturing equipment for a launch vehicle, and discloses a support device for welding the circular seam of the rocket body barrel section of a launch vehicle, comprising a plurality of auxiliary supports [2] radially arranged around an inner frame [1] , the outer end of the auxiliary support [2] is provided with an integral frame [5] and an arc-shaped support plate [7] in turn, and an integral airbag [4] is provided at the internal connection of the two, and the position is limited by the limit block [6]; Welding breakout plate [8] is embedded in the outer end of arc brace plate [7]. The invention achieves the beneficial effects of effectively, uniformly, neatly and quickly stretching apart the workpiece to be welded, and good bonding.

Description

Circumferential welded support device for launch vehicle rocket body section technical field The invention relates to rocket body manufacturing equipment of a launch vehicle, in particular to a welding support device for the circular seam of the rocket body barrel section of the launch vehicle. Background technique The rocket body structure of the launch vehicle is assembled and welded by large thin-walled aluminum alloy. The main components are the front and rear short shells, the front and rear box bottoms and the middle barrel section. Each middle barrel section is composed of 4 arc-shaped wall panels. Finally, the cylinder sections are butted with each other, and the joints are welded to complete the annular seam formation of the storage tank. From the above, the cylinder section has the characteristics of large diameter and thin wall. However, thin-wall welding is prone to deformation, so there is a certain degree of difference in the circle segment and diameter aft...
