As shown in fig. 1 to 12, the adjustable double-wire smoking welding gun comprises a welding gun head 1 and a welding cable 2 connected with the welding gun head 1, wherein the welding gun head 1 comprises a gun shell 11 and a bent neck 12 positioned in front of the gun shell 11, a double-welding-wire contact tip 13 is arranged in the bent neck 12, and two welding wires can be simultaneously accommodated in the double-welding-wire contact tip 13. The outside of the bent neck 12 is sleeved with a smoke absorbing outer sleeve 14, and the smoke absorbing outer sleeve 14 is detachably connected to the gun shell 11 through a smoke absorbing sleeve 15, so that maintenance and replacement are facilitated. A mutually communicated smoking flow channel 16 is formed in the smoking outer sleeve 14, the smoking sleeve 15, the gun shell 11 and the welding cable 2, a smoking mouth 17 which is connected with the smoking outer sleeve 14 in a sliding way is arranged at the joint of the smoking outer sleeve 14 and the bent neck 12, and an air suction hole 151 and an adjusting sleeve 18 for adjusting the opening size of the air suction hole 151 are circumferentially arranged on the smoking sleeve 15. The smoke generated by welding enters the smoking flow channel 16 through the smoking mouth 17 to improve the quality of the welding environment. The opening size of the air suction port is adjusted through the adjusting sleeve 18, so that the air protection effect of the molten pool part is ensured.

In one embodiment, the wire guide guides two welding wires simultaneously into the welding cable 2, and the welding wires pass through the double-wire contact tip 13 of the welding gun head 1 along the extending direction of the welding cable 2 until the welding wires contact with the welding point of an object to be welded, so as to carry out welding operation. A large amount of smoke and dust are generated during welding, the smoke and dust near a welding point enters the smoking flow channel 16 through the smoking mouth 17, meanwhile, the outside air enters the smoking flow channel 16 through the air suction port, and the smoke and dust filter filters the welding smoke and dust in the smoking flow channel 16, so that the welding efficiency is improved, the welding environment quality is improved, the harm of the welding smoke and dust to a human body is reduced, and the body health of workers is protected.

Wherein, the smoking outer sleeve 14 is detachably connected to the gun shell 11 through the smoking sleeve 15, and since the smoking outer sleeve 14 is close to the welding point and belongs to a wearing part, the smoking outer sleeve 14 is detachably connected to the gun shell 11 through the smoking sleeve 15, which is beneficial to the maintenance and replacement of the smoking outer sleeve 14. The soot filter has an air suction function, and can allow the gas in the smoking flow path 16 to enter the soot filter along the extending direction of the smoking flow path 16. The mouthpiece 17 can absorb smoke at the welding point to improve the welding quality. The air suction holes 151 can absorb air entering the smoking flow channel 16 to perform air protection on the molten pool part, and the welding quality of the welding seam in a narrow space is improved.

Preferably, the adjusting sleeve 18 is sleeved on the smoking sleeve 15, the adjusting sleeve 18 is provided with adjusting holes 181 corresponding to the air suction holes 151, the size of the air suction holes 151 is the same as that of the adjusting holes 181, and the adjusting sleeve 18 can rotate along the axis of the smoking sleeve 15 to adjust the size of the air suction holes 151.

The opening degree of each suction hole 151 is adjusted by rotating the adjusting sleeve 18, thereby adjusting the suction capacity of the suction hole 151. The size of the structure of the air suction hole 151 itself is fixed, and the opening degree of the air suction hole 151 means the opening degree of the air suction hole 151 when the air suction hole 151 communicates with the smoking flow path 16 and the external space.

Preferably, the distance between the adjacent suction holes 151 is greater than the width of the suction holes 151, and the distance between the corresponding adjacent adjusting holes 181 is greater than the width of the adjusting holes 181. So that the inner wall of the adjusting sleeve 18 can completely block the air suction hole 151 when the adjusting sleeve 18 rotates.

Preferably, the mouthpiece 17 is slidably fitted to the smoking outer jacket 14 in the extending direction of the smoking outer jacket 14, the mouthpiece 17 has a tapered portion 171 abutting against the curved neck 12, and the tapered portion 171 is provided with a smoking hole 172 to help adjust the amount of smoke sucked through the smoking hole 172.

In one embodiment, the mouthpiece 17 is adjusted by sliding along the outer smoking sleeve 14 to adjust the distance between the mouthpiece 17 and the welding point when welding, and thus the distance between the smoking holes 172 and the welding point. When the smoke suction hole 172 is close to the welding point, the smoke suction hole 172 has strong absorption capacity on welding smoke dust; conversely, when the smoke holes 172 are farther from the weld, the smoke holes 172 have a weaker absorption capacity for the weld fumes. Therefore, the suction amount of the welding fume at the welding spot is adjusted by adjusting the distance from the mouthpiece 17 to the welding spot.

Preferably, a nozzle 19 is fixed at the end of the bending neck 12, the double-welding-wire contact tip 13 is arranged inside the nozzle 19, and the double-welding-wire contact tip 13 adopts an elliptical hole structure. The gap between the short edge of the elliptical hole and the welding wire is very small, so that the two welding wires can only be arranged and passed through the long edge, the design is favorable for the welding wire to smoothly pass through the double-welding-wire contact nozzle 13, and the good conductivity of the welding wire is ensured.

Preferably, the rear end of the double-welding-wire contact tip 13 is connected with a ceramic transition piece 131, two welding wire holes 132 are formed in the ceramic transition piece 131, so that a welding wire has good directivity when entering the double-welding-wire contact tip 13, and the double-welding-wire contact tip 13 with the elliptical hole and the ceramic transition piece 131 are combined with each other to ensure the outlet direction and the conductivity of the welding wire.
