Anti-deformation assistive tool for welding thin-wall box bodies

Abstract

An anti-deformation assistive tool for welding thin-wall box bodies comprises an inner fixing frame and an outer clamp. The inner fixing frame comprises a box body, movable pressing blocks and adjusting bolts. Two adjacent faces of the box body are respectively connected with one movable pressing plate through the adjusting bolts, and by means of adjusting the adjusting bolts, relative distance between the movable pressing blocks and connecting faces of the box body where the movable pressing blocks are located can be adjusted. The two movable pressing blocks and the other two faces of the box body jointly form supporting for two lateral walls of the inner cavity of a thin-wall box body. The outer clamp comprises a cramp frame and a movable handle pressing bolt, the cramp frame is clamped outside two opposite lateral walls of the thin-wall box body, the movable handle pressing bolt is connected on one clamping finger of the cramp frame, a bolt head part of the movable handle pressing bolt is pressed on the lateral wall of the thin-wall box body. The anti-deformation assistive tool for welding the thin-wall box bodies utilizes the adjustable supporting to fix shape and position of the inner cavity in the box body, enables size of a supporting face and the size of the inner cavity of the box body to be consistent through the adjusting bolts, and then utilizes the external clamping, thereby enabling the box body to be stable in structure, effectively reducing deformation during welding, overcoming the shortcomings that in the prior art, only external clamping is utilized, and deformation of shape dimension contracting during cooling after welding can not be controlled, and welding quality of products is improved.

Description

technical field [0001] The invention relates to a welding anti-deformation aid, in particular to a welding anti-deformation aid for a square box, which can adapt to the welding of a square box with thin walls and high technical precision requirements. Background technique [0002] The swing outrigger is an important part of the vehicle-mounted gun. It bears the recoil force of the shell launch, and carries different radial and axial forces with the traction of the truck and the change of the shell launch angle. Therefore, in order to prevent the welding seam Blast off, welding is very critical. [0003] Usually the swing leg is a box structure, because it is an important force-bearing part, the welding must be sufficient, but the box is thin-walled, and the welding deformation is large. It is very difficult to control the welding deformation of the box, which will affect the subsequent processing, cause a high repair rate, and even cause waste products. Contents of the in...
