Abstract
Description
Technical Field
[0001] The utility model belongs to the field of welding devices, in particular to a small welding device. Background Art
[0002] Traditional welding processes are mostly carried out in an air environment, but this welding method cannot isolate the air. Moisture, dust and other debris in the air may enter the weld and affect the quality of the welding. Some metals with high chemical activity, such as stainless steel, titanium alloy, aluminum alloy and other metals, are prone to oxidation reactions with oxygen in the air during the welding process, producing oxidized compounds at the welding position, affecting the quality of the weld and reducing the strength and airtightness of the welded joint. Sealed welding devices are usually used when welding such metals, but the commonly used sealed welding devices are expensive and require calibration and adjustment during use. The operation process is cumbersome and prone to errors, and the welding cost is high. It is not convenient for welding small, chemically active metal parts. Utility Model Content
[0003] The utility model aims to provide a small welding device to solve the technical problems that the traditional welding process cannot isolate the air, moisture, dust and other debris in the air may enter the weld and affect the quality of welding; the commonly used sealing welding devices are expensive, require calibration and adjustment when in use, the operation process is cumbersome and prone to errors, and the welding cost is high, which is not convenient for welding small highly chemically active metal parts.
[0004] To achieve the above purpose, the specific technical solution of the small welding device of the utility model is as follows:
[0005] A small welding device comprises a bottle body; a workbench is arranged in the bottle body; an upper cover is arranged on the upper side of the bottle body; a tower-shaped rubber ring is arranged in the middle of the upper cover; a welding gun is arranged in the middle of the tower-shaped rubber ring and extends to the upper side of the workbench in the bottle body; a grounding pole is arranged on one side of the workbench and passes through the upper cover to extend to the outside of the bottle body; a ventilation pipe is arranged on the side of the upper cover opposite to the grounding pole and is connected with the space in the bottle body.
[0006] Furthermore, a sealing ring is provided between the upper cover and the bottle body.
[0007] Furthermore, the upper cover and the bottle body are fixed by a clamp.
[0008] Furthermore, the ventilation tube is connected to the outer port of the bottle body to cooperate with the inflation and exhaust equipment.
[0009] The small welding device of the utility model has the following advantages: by arranging the bottle body, the workbench, the upper cover, the tower-shaped rubber ring, the grounding column and the welding gun, the metal parts can be welded on the workbench in the bottle body, so that the air environment around the welding work is well sealed, and the moisture, dust and other debris in the air can be prevented from entering the weld and affecting the welding quality; when welding metals with high chemical activity, a vent pipe is arranged on one side of the bottle body, and the vent pipe is connected to the three-way device and the filling and exhausting equipment at the outer port of the bottle body through the vent pipe. Before welding starts, the cavity in the bottle body is evacuated through the vent pipe and the three-way device is connected to the outer port of the bottle body through the vent pipe and the filling and exhausting equipment, and then inert gases such as nitrogen and argon are filled. After repeating this three times, the welding work can be started on the workbench, so that the inert gas can protect the metal with high chemical activity, and the air can be prevented from oxidizing the metal with high chemical activity and affecting the welding quality, thereby ensuring the reliability and durability of the welded joint.

[0013] In order to better understand the purpose, structure and function of the utility model, the small welding device of the utility model is further described in detail below in conjunction with the accompanying drawings.
[0014] like Figure 1-2 As shown, the small welding device of the utility model comprises a bottle body 1; a workbench 2 is arranged in the bottle body 1; an upper cover 3 is arranged on the upper side of the bottle body 1; the upper cover 3 and the bottle body 1 are fixed by a clamp 9, and a tower-shaped rubber ring 4 is arranged in the middle of the upper cover 3; a welding gun 5 is arranged in the middle of the tower-shaped rubber ring 4 and extends to the upper side of the workbench 2 in the bottle body 1; a grounding pole 6 is arranged on one side of the workbench 2 and extends through the upper cover 3 to the outside of the bottle body 1; a ventilation pipe 7 is arranged on the side of the upper cover 3 opposite to the grounding pole 6 and is connected to the space inside the bottle body 1.
[0015] Combination Figure 1-2As shown, when in use, the upper cover 3 is opened, the metal piece to be welded is placed on the workbench 2, the upper cover 3 is fixed to the bottle body 1 by the clamp 9, so that a closed space is formed in the bottle body 1, and then the welding gun 5 is used to weld the metal piece on the workbench 2, and the grounding column 6 is used to provide a grounding effect for the workbench 2 and the metal to be welded. The tower-shaped rubber ring 4 can ensure the sealing effect inside the bottle body 1 while giving the welding gun 5 a certain range of movement, so that the welding gun 5 can perform free welding. The welding device makes the air environment around the welding work more airtight, preventing moisture, dust and other debris in the air from entering the weld and affecting the quality of welding.
[0016] A sealing ring 8 is provided between the upper cover 3 and the bottle body 1, and the upper cover 3 and the bottle body 1 are clamped together with the clamp 9. The provision of the sealing ring 8 can increase the sealing performance inside the bottle body 1, ensuring that there will be no gas leakage in the closed cavity formed by the bottle body 1 and the upper cover 3 during the welding process, so that air and dust will not affect the welding quality.
[0017] The vent pipe 7 is connected to a three-way device at the outer port of the bottle body 1 to cooperate with the filling and exhausting equipment. When welding metals with high chemical activity, the vent pipe 7 arranged on one side of the bottle body 1 is used to connect the three-way device to the outer port of the bottle body 1 to cooperate with the filling and exhausting equipment. Before welding begins, the inner cavity of the bottle body 1 is evacuated through the vent pipe 7, and then filled with inert gases such as nitrogen and argon. After repeating this process three times, welding work is started on the workbench 2, so that the inert gas can protect the metals with high chemical activity, prevent air from oxidizing the metals with high chemical activity and affecting the welding quality, thereby ensuring the reliability and durability of the welded joint.
