[0023] Example 1

[0024] See also Figure 1 , Figure 2 and Figure 4 A vehicle air conditioning pipeline auxiliary welding device includes a support seat 1, a rotating frame 2 is rotatably provided on the upper part of the support seat 1, a support plate 201 is rotatably provided on the lower part of the support seat 1, the support plate 201 is located below the rotating frame 2, a clamping frame 3 for clamping the pipeline is fixedly connected to the top of the rotating frame 2 by welding, a screw 401 is rotatably provided on the right side of the bottom of the rotating frame 2, the screw 401 is threadedly connected to the support plate 201, the rotating frame 2 can be raised and lowered by rotating the screw 401 to achieve height adjustment, and a knob is fixedly connected to the bottom end of the screw 401 by welding 4. A first guide rod 402 is fixedly connected to the left side of the bottom of the rotating frame 2 by welding. The first guide rod 402 slides through the support seat 1. The first guide rod 402 is used to guide the rotating frame 2 when the rotating frame 2 is raised or lowered. A placement frame 12 for storing parts is fixedly connected to the rotating frame 2 to facilitate the staff to take and use them. An S-shaped placement frame 13 for placing a welding gun is fixedly connected to the support seat 1. After welding is completed, the welding gun can be temporarily placed on the S-shaped placement frame 13 without the need for the staff to hold it. A liquid storage cylinder 14 for storing flux is provided on the S-shaped placement frame 13.

[0025] During use, the staff can turn the knob 4 according to their own height to make the screw 401 drive the rotating frame 2 to rise and fall, thereby achieving height adjustment, which is convenient for staff of different heights to use. After the height adjustment is completed, the pipe head is placed upward on the clamping frame 3 for fixation, and then the staff steps on the rotating frame 2 with their feet to rotate it for multi-angle welding.

[0026] Example 2

[0027] Based on Example 1, please refer to Figure 3 The clamping frame 3 has two symmetrically distributed movable frames 5 slidably arranged on the upper part thereof, and a clamping plate 6 for fixing the pipeline is fixedly connected to the upper part thereof. The clamping plate 6 is arc-shaped, and is convenient for clamping the pipeline for fixing. A first elastic member 7 is connected between the two movable frames 5.

[0028] See also Figure 3 Two second guide rods 801 symmetrically distributed on the left and right are fixedly connected to the lower part of the rotating frame 2, and a pedal 8 is slidably provided on the two second guide rods 801. A second elastic member 802 is sleeved on the second guide rod 801 to reset the pedal 8. The two ends of the second elastic member 802 are respectively connected to the pedal 8 and the support plate 201. Two connecting frames 9 symmetrically distributed on the left and right are fixedly connected to the rear side of the pedal 8 by welding. The two connecting frames 9 are jointly fixedly connected with a wedge-shaped push block 10 by welding. A wedge-shaped block 11 in contact with the wedge-shaped push block 10 is fixedly connected to the movable frame 5. The upward movement of the wedge-shaped push block 10 can squeeze the wedge block 11 to move outward.

[0029] Initially, the wedge-shaped push block 10 is located between the two wedge-shaped blocks 11, and the first elastic member 7 is in a stretched state. When the pipeline is placed, the pipeline head is clamped between the two clamping plates 6. Then, when stepping on the rotating frame 2, the pedal 8 is stepped on, and the second elastic member 802 is compressed accordingly. The pedal 8 drives the wedge-shaped push block 10 to move downward through the connecting frame 9, and the wedge-shaped push block 10 is out of contact with the wedge block 11. Under the elastic force of the first elastic member 7, the movable frame 5 drives the clamping plate 6 to move inward to clamp the pipeline head for fixing, so as to prevent the pipeline from moving or falling during the welding process. After the pipeline is welded, the rotating frame 2 is released, and under the elastic force of the second elastic member 802, the pedal 8 is reset upward, and the wedge-shaped push block 10 is re-inserted between the wedge push blocks 10, so that the movable frame 5 drives the clamping plate 6 to move outward to release the pipeline for removal.
