DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0014] Please refer to Figures 1-3This utility model provides an inert gas shielded welding device, including a welding platform 1. An L-shaped support plate 12 is fixedly mounted on one side of the surface of the welding platform 1. An adjustment structure 9 is mounted on the inner wall of the L-shaped support plate 12. A welding protective cover 3 is fixedly mounted on the lower end of the adjustment structure 9. A limit rod 10 is fixedly mounted on one side of the surface of the welding protective cover 3. The limit rod 10 is inserted through and inserted into the inner wall of the L-shaped support plate 12. Welding gloves 4 are symmetrically and sealed on both sides of the welding protective cover 3. The welding gloves 4 are inserted into the inner cavity of the welding protective cover 3. A sealing suction cup 13 is fixedly connected to the lower end of the welding protective cover 3. A solenoid valve 5 is connected to one side wall of the welding protective cover 3 through an air inlet pipe 6. A vacuum pump 7 is fixedly connected to the other side wall of the welding protective cover 3. An observation window 11 is fitted onto the surface of the welding protective cover 3.

[0015] Welding platform 1 facilitates welding of workpieces. The welding protective cover 3 and sealing suction cup 13 work together to ensure a protective gas seal for the workpiece. Adjusting structure 9 and limiting rod 10 allows the welding protective cover 3 to fit onto the surface of welding platform 1, while the sealing suction cup 13 adheres to the welding platform 1, ensuring effective welding protection. As needed, vacuum pump 7 first evacuates the space inside welding protective cover 3. Once the vacuum level reaches the set value, vacuum pump 7 is turned off. The air intake of solenoid valve 5 is adjusted as needed, and inert protective gas is remotely connected and delivered to welding protective cover 3 through air intake pipe 6. Simultaneously, welding gloves 4 are used to operate the welding machine on welding platform 1 to weld the workpiece, ensuring a tight seal. The welding torch is operated through observation window 11. After completion, the welding machine is turned off.

[0016] The adjusting structure 9 includes a nut seat 91, which is rotatably mounted on the inner wall of the L-shaped support plate 12. An adjusting screw 94 is screwed onto the inner wall of the nut seat 91. The lower end of the adjusting screw 94 is fixedly connected to the surface of the welding protective cover 3. A metal turntable 92 is fixedly mounted on the outer wall of the nut seat 91. A handle 93 is fixedly mounted on the surface of the metal turntable 92. An electromagnet 95 is fixedly connected through the inner wall of the L-shaped support plate 12. The electromagnet 95 is attracted to the metal turntable 92.

[0017] When the adjustment structure 9 is needed, first turn off the electromagnet 95 to release the attraction and restraint on the metal turntable 92. Then, turn the handle 93, which will drive the nut seat 91 to rotate through the metal turntable 92. Due to the screw connection between the nut seat 91 and the adjusting screw 94, and the limiting effect of the limiting rod 10 on the surface of the welding protective cover 3, the adjusting screw 94 will not rotate with the nut seat 91. When the nut seat 91 is rotated, the adjusting screw 94 will move up and down on its inner wall, and drive the welding protective cover 3 to move up and down. When the welding protective cover 3 is needed, adjust its downward movement and drive the sealing suction cup 13 to seal and adhere to the welding platform 1, thus completing the setting of the welding protective cover 3.

[0018] The lower end of the welding platform 1 is fixedly equipped with a support leg 2.

[0019] The support leg 2 serves to protect the welding platform 1.

[0020] A support 8 is fixedly mounted on the lower end of the vacuum pump 7, and the support 8 is fixedly connected to the side wall of the welding protective cover 3.

[0021] Support 8 can better ensure the working stability of vacuum pump 7.
