Description

Technical Field

[0001] The utility model relates to the technical field of welding guns, and more specifically to a handheld auxiliary swinging welding gun. Background Art

[0002] A welding gun is a tool used for arc welding, usually used to connect two or more metal parts by melting metal. The selection and use of a welding gun requires consideration of many factors, including the type and thickness of the welding material, the required welding current, the conditions of the working environment, etc. Correct welding gun operation can ensure welding quality and operator safety.

[0003] After searching, a Chinese patent with the announcement number CN220698497U discloses a welding gun. In order to solve the problem that the welding nozzle of the gas welding gun may be blocked, the acetylene tube may leak, or the user may operate it incorrectly during use, thereby causing the mixed gas to flow back, the flame to enter the gas pipe, and then cause the safety accidents of backfire and gas welding gun explosion, the transmission component and the second spring are set so that when the acetylene valve is in the closed state, the diverter pipe cannot be opened and oxygen cannot flow; during the closing process of the acetylene valve, the shut-off slider is driven to automatically reset and close the diverter pipe. Through the setting of the mixed gas pipe, the oxygen in the welding oxygen pipe and the acetylene gas in the acetylene tube are mixed, so that they can be fully ignited at the welding gun mouth.

[0004] During the use of the handheld welding gun, the welding gun is often manually controlled to swing. Manually controlling the swing of the welding gun is difficult to ensure the uniformity and stability of the swing, which easily leads to uneven heating at the welding point, and then the weld width and height are uneven. This not only affects the appearance and geometric dimensions of the weld, but also reduces the strength and sealing of the weld, making it difficult to ensure the high precision and quality of the weld.

[0014] Technical effects and advantages of the utility model:

[0015] 1. By setting a swing mechanism, the motor drives the rotating shaft to rotate, thereby driving the welding gun to rotate through the fixed plate, the rotating plate and the fixed sleeve. The back and forth swing of the welding gun can make the welding point more evenly heated, avoid the situation that the weld is uneven in width and height, thereby obtaining a good weld appearance and geometric size, improving the strength and sealing of the weld, helping to discharge impurities and gases in the molten pool, reducing slag inclusion defects in the weld, improving the purity and quality of the weld, and being able to evenly heat and weld the weld.
