Description

TECHNICAL FIELD

[0001] The utility model relates to the field of metal piece welding, especially a double-sided welding argon arc welding equipment. BACKGROUND

[0002] Argon arc welding is a kind of welding technology using argon as a protective gas, also known as argon gas shielded welding. It is to pass argon protective gas around the electric arc welding to isolate air outside the welding area and prevent oxidation. In the prior art, argon arc welding is carried out by a welding gun.

[0003] The current argon arc welding equipment can be divided into handheld portable and integral welding machines. When using the handheld portable argon arc welding machine, the operator needs to manually hold the welding machine and manually place the workpiece inside the machine for fixation before automatic welding.

[0004] However, when operating the handheld argon arc welding machine, the operator needs to manually hold the device and manually place the workpiece, which can easily cause misalignment of the metal workpiece inside the device.

[0005] Therefore, it is necessary to provide a double-sided welding argon arc welding equipment to solve the above technical problems. SUMMARY

[0006] The utility model provides a double-sided welding argon arc welding equipment, which solves the problem of misalignment of the metal workpiece inside the device when operating the handheld argon arc welding machine, which needs to manually hold the device and manually place the workpiece.

[0007] To solve the above technical problems, the utility model provides a double-sided welding argon arc welding equipment, which comprises:

[0008] A welding machine body, a fixing assembly is arranged on the surface of the welding machine body;

[0009] Two fixing blocks, the two fixing blocks are arranged on the two sides of the welding machine body, respectively;

[0010] A lifting assembly, the lifting assembly is arranged between the two fixing blocks;

[0011] A base, the base is arranged below the lifting assembly.

[0012] Principle of the welding arc of the welding machine body 1:

[0013] The welding arc can be generated as follows:

[0014] TIG welding arc generation principle

[0015] In TIG (tungsten inert gas welding), when the welding power supply is turned on, a certain voltage is applied between the tungsten electrode and the workpiece. Due to the action of the electric field, the electrons at the tip of the tungsten electrode are accelerated and emitted towards the workpiece. When these high-speed electrons hit the surface of the workpiece, they ionize the atoms on the surface of the workpiece, generating positive ions and more electrons. These ions and electrons form a plasma under the action of the electric field, thereby generating a welding arc.

[0016] Argon gas, as a protective gas, forms a stable protective cover around the arc to prevent air from entering the welding area.

[0017] MIG / MAG welding arc generation principle

[0018] In MIG / MAG (gas shielded arc welding), the welding wire serves as an electrode, and the workpiece serves as the other electrode. When the welding power supply is turned on, a voltage is applied between the welding wire and the workpiece. The metal at the end of the welding wire melts under the action of the electric field and forms a droplet. At the same time, due to the action of the electric field, the gas between the welding wire and the workpiece is ionized to form a plasma, generating a welding arc.

[0019] Protective gas (such as carbon dioxide or mixed gas) is sprayed from the welding gun to protect the welding area and prevent the droplet and molten pool from being oxidized.

[0020] Preferably, the fixing assembly comprises a first fixing sleeve, and the bottom of the first fixing sleeve is connected with a U-shaped fixing rod.

[0021] Preferably, one end of the U-shaped fixing rod is connected with a second fixing sleeve, and the first fixing sleeve and the second fixing sleeve are respectively connected to the surface of the welding machine body.

[0022] Preferably, the lifting assembly comprises two telescopic rods, and the interiors of the two telescopic rods are respectively provided with a fixing bolt.

[0023] Preferably, the interior of the telescopic rod is provided with a plurality of fixing holes matched with the fixing bolt.

[0024] Preferably, a moving assembly is arranged between the telescopic rod and the base, and the moving assembly comprises a connecting ring, the two sides of the connecting ring are symmetrically connected with a supporting rod, the bottom of the supporting rod is connected with a moving block, and the surface of the base is provided with a moving groove matched with the moving block.

[0025] Preferably, the interior of the moving block is provided with a connecting bolt.

[0026] Compared with the related art, the argon arc welding equipment for double-sided welding has the following beneficial effects:
