Thick plate titanium alloy welding adjustable device

Abstract

The invention discloses a thick plate titanium alloy welding adjustable device, and relates to the technical field of welding. The thick plate titanium alloy welding adjustable device comprises a lifting mechanism and a rotating mechanism; the rotating mechanism is located at the top of the lifting mechanism and rotationally matched with the lifting mechanism; the lifting mechanism is composed of a lifting mechanism body and a mounting assembly; and the mounting assembly is located at the bottom in a fixing assembly and is in sliding fit with the fixing assembly. Through the design of the mounting assembly and the fixing assembly, height adjustment in the thick plate titanium alloy welding process is achieved, and under the acting force of a first spring, a certain buffering effect is achieved; through the design of the rotating mechanism, angle adjustment in the thick plate titanium alloy welding process is achieved, and the working efficiency is improved; and thick plate titanium alloys with different specifications and sizes are fixedly clamped by placing the thick titanium alloy plates on the top of a rotating table, fixing second springs to one side faces of arc-shaped clamping plates and rotating fit between rotating rods and circular thin rods.

Description

technical field [0001] The invention belongs to the field of welding technology, in particular to an adjustable device for thick plate titanium alloy welding. Background technique [0002] Commonly used welding methods for titanium alloys are: argon arc welding, submerged arc welding, vacuum electron beam welding, etc. Tungsten argon arc welding is used for thickness below 3 mm, and metal argon arc welding is used for thickness above 3 mm; the purity of argon gas is not less than 99.99%, and the content of air and water vapor in argon gas is strictly controlled; degreasing and oxidation removal are carried out before welding Surface treatment of skin and oxide film removal; due to the high chemical activity of titanium alloys, it is easily polluted by oxygen, nitrogen, and hydrogen, so electrode arc welding, oxyacetylene (or oxypropane, etc.) gas welding, C02 welding, atomic hydrogen welding, etc. cannot be used welding.
