The invention relates to an assembly automatic welding device, comprising: a main rotary table, an automatic wire filling and welding wire fine-tuning mechanism, an arc length tracker and a welding platform; a positioner is installed on the main rotary table, and the variable A chuck is installed on the bit machine, and the chuck is used to hold and fix the assembly; the assembly includes a first end cover and a second end cover; the first end cover is hoisted on the chuck, and the The second end cover is hoisted on the first end cover, and then a cover plate is used to press the second end cover to form a welding cavity; a hollow bolt is also installed on the cover plate; the invention utilizes the cover plate to seal the welding cavity , and then set the air inlet and outlet holes on the hollow bolts, so that the welding inner cavity is filled with protective gas, thus solving the problem of uneven protection inside the cavity and difficulty in applying protective gas; use hollow bolts to connect the two ends of the cover. It has the function of fixing the two end caps, which is beneficial to reduce the work intensity of the welder.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to an assembly automatic welding device. Background technique [0002] At present, in the field of welding, the conventional two-pipe butt welding process is relatively mature, and the welding shape is better. For pipe fittings with low general requirements, the protection requirements can be met by only applying shielding gas to the outside of the pipe fittings, and welding without shielding gas on the inner wall of the pipe fittings; however, for some pipe fittings with higher requirements, such as weld protection requirements Strict, and the base metal is easy to oxidize, it is difficult to meet the protection requirements by applying shielding gas to the outside of the pipe fittings, and the welding method without shielding gas on the inner wall of the pipe fittings. [0003] In order to meet the higher protection requirements of the pipe fittings, it is necessary to add a shi...
