Abstract

The invention discloses a work fixture for penetration welding of a T-shaped structure and a clamping method.The fixture comprises a base, multiple sets of pressing mechanisms, a jacking mechanism and an air pipe, a strip-shaped groove is formed in the top of the base, the multiple sets of pressing mechanisms are arranged on the periphery of the top of the base, the pressing mechanisms are used for pressing a flat plate in a T-shaped plate, the jacking mechanism is arranged in the strip-shaped groove, and the air pipe is arranged in the strip-shaped groove; a mounting groove is formed in the jacking mechanism, the jacking mechanism is used for fixing a vertical plate in the T-shaped plate in the strip-shaped groove so that the vertical plate can abut against the bottom face of the flat plate, the air pipe is arranged in the mounting groove, a plurality of air outlet holes are formed in the air pipe in the length direction of the air pipe, the air outlet holes are all close to the contact position of the flat plate and the vertical plate, and the air pipe is used for conveying protective gas. The device has the advantages that the gas protection effect can be guaranteed, deformation control is facilitated, the welding quality is high, and the penetration welding requirement of the T-shaped structure is met.

Description

technical field [0001] The application relates to the technical field of welding tooling, and in particular, to a tooling fixture and a clamping method for penetration welding of T-shaped structures. Background technique [0002] Titanium alloys have become an important structural material in the aerospace field due to their many superior properties, such as light specific gravity, high specific strength, and good high temperature performance and corrosion resistance. The traditional welding method of flat T-shaped structure is usually to weld on both sides or one side of its root (see Figure 4 ), the root of the weld is subjected to two welding heat effects, resulting in large welding deformation. To solve the above problems, penetration welding techniques (see Figure 5 ) came into being. The penetration welding technology is to apply a welding heat source from the back of the flat T-shaped structure to melt the material to be welded, so as to achieve the effect of sing...
