Adjustable gas protection dragging cover for titanium alloy multi-angle angle joint welding

Abstract

The utility model discloses an adjustable gas protection dragging cover for welding a titanium alloy multi-angle angle joint. The adjustable gas protection dragging cover comprises a dragging cover fan-shaped shell, a first fan-shaped sliding plate and a second fan-shaped sliding plate, wherein the first fan-shaped sliding plate and the second fan-shaped sliding plate are arranged on the two sides of the dragging cover fan-shaped shell; rotary positioning assemblies facilitating rotation of the first fan-shaped sliding plate and the second fan-shaped sliding plate are arranged at the two ends of the dragging cover fan-shaped shell in the length direction of the dragging cover fan-shaped shell. The first fan-shaped sliding plate and the second fan-shaped sliding plate rotate relative to the dragging cover fan-shaped shell through the rotary positioning assembly, and a gas protection dragging cover closing state and a gas protection dragging cover multi-angle adjusting state are formed. According to the utility model, through self-adjustment, welding protection of angle joints with various angles and joint forms can be rapidly adapted. The gas protection dragging cover is easy to manufacture, low in cost and convenient to operate, and the production efficiency of welding of the titanium alloy complex component is improved.
