[0024] With the setting of the positioning plate 23, when welding the pipeline is required, only need to push the welding ends of the two sides of the pipeline to the front and back sides of the positioning plate 23. After the pushing is completed, drive the positioning plate 23 to leave the processing area through the driving cylinder 24. At this time, the distances between the welding ends of the two pipelines and the welding processing area are equal, avoiding the situation of misalignment and readjustment during welding.

[0025] The fixing component 3 includes a fixing frame 31 arranged on the top of the base 1. A sliding rod 32 is longitudinally arranged inside the fixing frame 31. Two moving frames 33 are slidably arranged on the peripheral side of the sliding rod 32 along its length direction. Pressing frames 34 are slidably arranged up and down on the inner sides of the two moving frames 33.

[0026] By the rotation of the rotating disc 4, drive the screw rod 39 to move downward in the moving frame 33. Cooperate with the slidably arranged pressing frame 34 to move the pressing frame 34 downward, and at the same time drive the pressing plate 36 to move downward to press and clamp the top of the pipeline.

[0027] The positioning component 2 further includes a driving cylinder 24 arranged on the right side of the left support plate 21. The telescopic end on the right side of the driving cylinder 24 is fixedly connected to the top of the positioning plate 23. A rotating screw rod 25 is longitudinally rotatably arranged inside the fixing frame 31 and on the left side of the sliding rod 32. The peripheral side of the rotating screw rod 25 is threadedly connected to the inner sides of the two moving frames 33.

[0028] After the positioning plate 23 leaves the processing area, drive the rotation of the rotating screw rod 25 through the rotation of the output end of the driving motor 27.

[0035] First step: During use, place the two pipelines to be welded into the front and rear moving frames 33 respectively, and push the two pipelines to move relatively. When the welding ends of the pipelines abut against the front and rear sides of the positioning plate 23, rotate the rotating disk 4 to drive the screw 39 to move downward inside the moving frame 33, and then drive the pressing plate 36 to move downward to fix the two pipelines.

[0036] Second step: By retracting the extending end of the driving cylinder 24, drive the positioning plate 23 to move leftward on the limit slide bar 22, thereby leaving a space on the opposite side of the two pipelines. Drive the rotation of the rotating lead screw 25 by the rotation of the output end of the driving motor 27. With the arrangement of the sliding bar 32, drive the front and rear two clamped pipelines to move relatively at a constant speed. Finally, the butt joint of the pipelines stays at the processing position of the butt welder. When the pipeline is clamped and welded, part of the possible vibration will be offset by the elastic deformation of the spring 37, reducing the damage to the pipeline by the clamping piece.

[0037] Compared with the related technology, a double-bracket butt welding structure device for an automobile heater water pipe provided by the present utility model has the following beneficial effects:

[0038] Push the welding ends of the two pipelines to make them abut against the front and rear sides of the positioning plate 23. After fixation, retract the extending end of the driving cylinder 24 to drive the positioning plate 23 to move leftward on the limit slide bar 22. Drive the rotation of the rotating lead screw 25 by the rotation of the output end of the driving motor 27. With the arrangement of the sliding bar 32, drive the front and rear two clamped pipelines to move relatively at a constant speed. Finally, the butt joint of the pipelines stays at the processing position of the butt welder. The structure is simple and practical, facilitating the support and positioning of the two pipelines to be welded, and improving the welding quality and efficiency of the water pipe.
