The supporting device is set; the upper part of the automatic rotating bracket is provided with a welding cavity, and the nozzle is fixed in the welding cavity, and the positioning device is connected with the nozzle through the welding cavity; the top of the welding cavity is connected with the sealing device, and the shell that is welded with the nozzle is placed on the sealing device The contact position of the housing and the sealing device is sealed and connected by a seal; one end of the supporting device is connected to the lower part of the automatic rotating bracket, and the center of the bottom of the housing is located at the other end of the supporting device. The invention realizes the sealing of the welding cavity, ensures the filling of protective gas and the discharge of redundant air during the welding process, improves the quality of the weld seam, can effectively control the welding deformation, has simple operation, accurate welding positioning and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and is suitable for welding auxiliary equipment for welding air intake nozzles and filling nozzles of aerospace titanium alloy storage tank products with upper and lower shells, and in particular relates to an automatic rotary welding device. Background technique [0002] For aerospace titanium alloy storage tank products, the air intake nozzle and filling nozzle are welded with the upper and lower shells. During the welding process, the aerospace titanium alloy storage tank product requires the weld quality level between the air intake nozzle, filling nozzle and the shell High; the current welding equipment is not enough to meet the requirements of the welding grade, and the welding of titanium alloy materials is easy to produce bubbles, so the welding process requires high protection gas filling and sealing. [0003] At the same time, the intake nozzles and filling nozzles of such aer...

Problems solved by technology

[0002] For aerospace titanium alloy storage tank products, the air intake nozzle and filling nozzle are welded with the upper and lower shells. During the welding process, the aerospace titanium alloy storage tank product requires the weld quality level between the air intake nozzle, filling nozzle and the shell High; the current welding equipment is not enough to meet the requirements of the welding grade, and the welding of titanium alloy materials is easy to produce air bubbles, so the welding process has higher requirements for protective gas filling and sealing

[0003] At the same time, the intake nozzles and filling nozzles of this type of aerospace titanium alloy products are mostly special-shaped structural parts, which are difficult to locate relative to the welding position of the shell, and are prone to welding deformation. Traditional manual welding is difficult to meet the demand; moreover, the existing traditional Manual argon arc welding has low reliability of weld seam quality, difficult control of welding positioning size and welding deformation, complicated operation, low efficiency, and poor appearance consistency of weld seam
