The first supporting block 6 and the second supporting block 22 can support the pipeline 24, so that the pipeline 24 is prevented from rolling in the welding process, and the stability is enhanced; the second cylinder 11 can drive the movable plate 12 to move up and down, so that the second limiting block 23 presses the screw head 25, the stability of the screw head 25 is enhanced, and the welding gun 19 can weld the screw head 25 firmly; the operation of motor 13 can drive belt 14 and transfer line 15 and rotate, and then drives transmission block 16 and rotate, and transmission block 16 drives welder 19 on the connecting rod 18 and can carry out the circumferential rotation around the nipple 25 to can weld firmly to the junction of pulling out hole 26 and nipple 25, it is convenient high-efficient to use, and the practicality is good.
Further, the second rail 4 is horizontally parallel to the first rail 2 and is slidably connected to the bottom middle of the moving device 3. Second track 4 with first track 2 parallel arrangement has more stability when supporting with fixed pipeline 24, second track 4 sets up in 3 bottom sides middle parts of mobile device, place back on first supporting block 6 when the staff with pipeline 24, start first cylinder 5 and drive first supporting block 6 and upwards move to with first stopper 7 highly uniform, then mobile device 3 moves on first track 2, support pipeline 24 through first stopper 7, for the sequent welding process, it is convenient high-efficient to use.
Furthermore, the size of the first limiting block 7 is adapted to the inner diameter of the left port of the pipeline 24, and the pipeline 24 is movably connected with the first limiting block 7.
