[0027] A double-station welding tool for a pressure differential tube comprises: a base plate 1 and a pressure differential tube 7 to be processed, wherein a vertical plate 2 is arranged on the base plate 1, a first motor 3 is arranged on the vertical plate 2, a rotating shaft 4 is rotatably connected to the vertical plate 2, the rotating shaft 4 is connected to the output end of the first motor 3, a fixed bearing 5 is arranged at the other end of the rotating shaft 4, the rotating shaft 4 is rotatably connected to the vertical plate 2 via the fixed bearing 5, a mounting plate 6 is fixedly connected to the rotating shaft 4, steering mechanisms 8 are arranged on both sides of the mounting plate 6, and a first clamping portion 9 is arranged on the steering mechanism 8.

[0028] Both sides of the mounting plate 6 can be processed, which improves the processing efficiency, and the first motor 3 can be used to control the angle between the mounting plate 6 and the horizontal plane, which facilitates the welding work; the shape of the pressure differential tube is relatively complex, and the clamp required for welding also needs to adapt to its complex and changeable shape. The pressure differential tube 7 to be processed shown in the figure is Z-shaped. When processing the pressure differential tube 7 to be processed with different bending angles, adjust the steering mechanism 8 to change the angle of the first clamping part 9, and then clamp it.

[0029] The steering mechanism 8 includes a sliding rod 81, which is fixedly connected to the mounting plate 6, a sleeve rod 82 is slidably connected to the sliding rod 81, a fastener 83 is provided on the sleeve rod 82, a base 84 is fixedly connected to the sleeve rod 82, a first rotating part 85 is fixedly connected to the base 84, the first rotating part 85 is rotatably connected to the second rotating part 86, and the first clamping part 9 is provided on the second rotating part 86.

[0030] By loosening the fastener 83 , the position of the sleeve rod 82 on the sliding rod 81 can be adjusted, and the first rotating portion 85 and the second rotating portion 86 rotate in coordination to adjust the angle of the first clamping portion 9 .

[0031] A ratchet 87 is rotatably connected to one side of the second rotating portion 86 facing the first rotating portion 85 , and a baffle 88 is rotatably connected to the inside of the first rotating portion 85 . The baffle 88 corresponds to the position of the ratchet 87 .

[0032] When the first rotating part 85 and the second rotating part 86 rotate in coordination, the baffle 88 blocks the ratchet teeth of the ratchet wheel 87, making the rotation of the ratchet wheel 87 more stable. After the adjustment is completed, the ratchet wheel 87 will not be easily rotated again, thereby increasing stability.

[0033] The first clamping part 9 includes a first screw 91, a first guide rod 92 and a first clamping plate 94, the first clamping plate 94 is threadedly connected to the first screw 91, the first clamping plate 94 is slidingly connected to the first guide rod 92, one end of the first screw 91 is fixedly connected to a rotating wheel 93, and the first clamping plate 94 is fixedly connected to a first contact rod 95.

[0034] The rotating wheel 93 is rotated to drive the first screw rod 91 to rotate. The first screw rod 91 is a bidirectional screw rod. The two first clamping plates 94 move toward each other, so that the first contact rod 95 clamps the pressure differential tube 7 to be processed.

[0036] After the second motor 103 is started, it drives the second screw 101 to rotate. The second screw 101 is a bidirectional screw. The two second clamping plates 104 move toward each other, so that the second contact rod 105 clamps the pressure differential pipe 7 to be processed.

[0037] A tool box 11 is disposed on the outer side of the vertical plate 2 , and the tool box 11 is located directly below the fixed bearing 5 .

[0038] The tool box 11 is used to store the commonly used instruments and consumables for welding work, so as to facilitate their use.

[0039] The mounting plate 6 is provided with through slots 12 , which completely penetrate the mounting plate 6 . There are multiple groups of through slots 12 and the structural strength of the mounting plate 6 is not affected.

[0040] Under the premise of not affecting the structural strength of the mounting plate 6 , the provision of the through slot 12 reduces the overall weight of the mounting plate 6 .

[0041] The working principle of a double-station welding tool for differential pressure pipe provided by the utility model is as follows:

[0042] Both sides of the mounting plate 6 can be processed, which improves the processing efficiency, and the first motor 3 can be used to control the angle between the mounting plate 6 and the horizontal plane, which facilitates the welding work; the shape of the pressure differential tube is relatively complex, and the clamp required for welding also needs to adapt to its complex and changeable shape. The pressure differential tube 7 to be processed shown in the figure is Z-shaped. When processing the pressure differential tube 7 to be processed with different bending angles, adjust the steering mechanism 8 to change the angle of the first clamping part 9, and then clamp it.

[0043] Compared with the related art, the double-station welding tool for differential pressure pipe provided by the utility model has the following beneficial effects:

[0044] According to the different shapes of the pressure differential tube 7 to be processed, the direction of the first clamping part 9 can be changed by adjusting the steering mechanism 8 to ensure the clamping effect of the clamp and prevent the pressure differential tube 7 to be processed from being affected by the welding quality due to poor clamping effect during welding; welding can be carried out at the workstations on both sides of the mounting plate 6, which improves efficiency, and the first motor 3 can be used to control the mounting plate 6 to adjust the angle, which is convenient for welding work with special angles.
