Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a gas shielded electric welder. Background Art

[0002] As the name suggests, gas shielded arc welding is a special welding method that uses gas as a protective medium. It was originally designed to adapt to the welding of easily oxidized materials such as aluminum alloys, magnesium alloys, and stainless steel. However, after continuous development, gas shielded welding not only has better welding quality than traditional arc welding, but is also more efficient and cleaner. Therefore, it is widely used in many industries such as aviation, aerospace, machinery manufacturing, shipbuilding, and vehicle manufacturing.

[0044] First, the operator places the plate to be welded between the two clamps 8 and starts the No. 1 motor 4. As the No. 1 motor 4 runs, the round shaft 5 and the rotating rod 6 will begin to rotate. At this time, the two connecting rods 7 will start to rotate with the two ends of the rotating rod 6 as the axis under the drive of the rotating rod 6. At the same time, the other ends of the two connecting rods 7 will respectively drive the two clamps 8, so that the two clamps 8 begin to move toward each other along the inner surface of the placement plate 1. Finally, the two clamps 8 clamp the two steel plates and make them unable to move.

[0045] Then the operator starts the No. 2 motor 11, the No. 1 pneumatic cylinder 14 and the No. 2 pneumatic cylinder 19, wherein the operation of the No. 2 motor 11 will cause the lead screw 12 to start rotating, and the mounting seat 13 as a whole will start moving under the drive of the lead screw 12 and the limit of the limit column 10, the operation of the No. 1 pneumatic cylinder 14 will cause the mounting plate 15 as a whole to start moving downward, and the operation of the No. 2 pneumatic cylinder 19 will cause the hollow connecting block 20 to start moving, and the movement of the hollow connecting block 20 will drive the connecting column 18 and the rotating block 17, so that the rotating block 17 as a whole starts to rotate with the mounting shaft 16 as the axis, and finally under the joint action of the mounting seat 13, the mounting plate 15 and the rotating block 17, the shielding gas welding gun 26 will contact the welding point.

[0046] At this time, the operator starts the air pump 22 and the shielding gas welding gun 26. The operation of the air pump 22 will cause the shielding gas inside the shielding gas box 2 to enter the air pump 22 through the air inlet 23 and be discharged to the vicinity of the welding point after passing through the air outlet 24, the hose 25 and the shielding gas welding gun 26. The operation of the shielding gas welding gun 26 will weld the two plates.
