[0023] The utility model embodiment discloses an adjustable semi-automatic pipeline welding machine.

[0024] According to the attached Figure 1-2 As shown, including:

[0025] The chuck unit mainly comprises a chuck base 1 and a pipe chuck 101. The pipe chuck 101 is rotatably arranged on the top of the chuck base 1. The pipe chuck 101 is connected to a driving assembly.

[0026] A welding unit, the welding unit is arranged on a side of the chuck unit;

[0027] The welding unit includes:

[0028] The support column 3 is slidably connected to a welding oscillator 301 on its side, an air pipe 302 is arranged on the front of the welding oscillator 301, and a welding gun 303 is installed at the end of the air pipe 302, the end of the welding gun 303 is located on the side of the pipe chuck 101, and the welding gun 303 is transmission-connected to the welding oscillator 301.

[0029] During use, the pipe to be welded is first fixed by the pipe chuck 101, and then the welding oscillator 301 on the side of the support column 3 is slid to drive the welding gun 303 to move vertically, so as to move the welding gun 303 to a suitable position. At this time, the welding oscillator 301 is used to drive the welding gun 303 to swing left and right regularly, and cooperate with the driving component to drive the pipe chuck 101 to rotate, so as to achieve the effect of automatic welding.

[0030] Furthermore, the driving component includes:

[0031] The motor base 2 is fixedly mounted on the back of the chuck base 1, and a driving motor 201 is fixedly mounted on the top of the motor base 2;

[0032] The reducer 202 is fixedly installed above the motor base 2 , and the driving shaft of the driving motor 201 passes through the reducer 202 and is connected to the pipe chuck 101 .

[0033] Furthermore, a coupling 203 is installed between the reducer 202 and the pipe chuck 101 .

[0034] When the driving motor 201 is working, its driving shaft is decelerated by the reducer 202, and then the coupling 203 is used to drive the pipe chuck 101 to rotate slowly.

[0035] The welding oscillator 301, the driving motor 201, the reducer 202 and the coupling 203 are all mature equipment in the industry, and therefore will not be described in detail here.

[0036] It is particularly disclosed that a screw rod is rotatably connected inside the support column 3, and the top end of the screw rod extends upward and is fixedly connected to an adjusting wheel 304. A sliding groove is provided on the outer side of the support column 3, and a nut block threadably connected to the screw rod is slidably connected on the inner wall of the sliding groove.

[0038] When the adjusting wheel 304 is rotated, the screw rod is driven to rotate inside the support column 3, thereby driving the nut block threadedly connected to the screw rod to move vertically, and the nut block is fixedly connected to the lifting seat 305, thereby driving the welding oscillator 301 above the lifting seat 305 to move vertically.

[0039] Preferably, one end of the gas pipe 302 away from the welding gun 303 is connected to an external welding machine.

[0041] The adjusting link 306 may adopt the angular adjustment link disclosed in Chinese Patent Publication No. CN207762120U, which can be adjusted at multiple angles, so that the deflection angle of the welding gun 303 can be adjusted by adjusting the link 306, thereby facilitating the contact between the welding end of the welding gun 303 and the pipe on the pipe chuck 101.

[0042] Automatic welding has higher welding speed and precision, which can greatly improve production efficiency and shorten production cycle. The equipment runs stably, avoiding instability and errors caused by human factors, thereby improving welding quality. Automatic welding equipment can work continuously, reducing the labor intensity of workers and saving labor costs. During the use of automatic welding equipment, operators do not have to directly face the harm to workers' health caused by harmful substances such as welding smoke and arc light. The position of the welding gun 303 is manually adjusted in a semi-automatic manner, and the operation is simple and easy to learn. During the welding process, the welding oscillator 301 drives the swing amplitude of the welding gun 303 and the rotation speed of the pipe chuck 101 to be selected in a fixed mode or manually adjusted.
