[0030] In summary, as Figures 1-6 shown, when using this auxiliary device for non-destructive testing of metal pipes, first rotate the screws 361 above and below the two rotating gears 36, so that the screws 361 drive the arc-shaped anti-slip clamping plates 362 to move, and the arc-shaped anti-slip clamping plates 362 drive the guide rods 363 to move vertically, so as to clamp and fix the outer wall of the metal pipe body 2 inside the rotating gear 36.

The detection end of the flaw detector probe 5 can be moved above the outer wall of the metal pipe body 2, facilitating the non-destructive detection of the metal pipe body 2 by the flaw detector probe 5. At the same time, the output end of the servo motor 43 drives the lead screw 44 to rotate, and the lead screw 44 drives the adjustment block 45 to slide inside the support cover 41. The adjustment block 45 drives the first electric telescopic rod 46, the connecting frame 47, the mounting seat 48, the mounting frame 49, the second electric telescopic rod 491, the arc-shaped limit clamping plate 492 and the flaw detector probe 5 to move horizontally, facilitating the non-destructive detection of different positions of the metal pipe. Then, the double output ends of the dual-axis motor 32 drive the two connecting shafts 33 and the drive gears 35 to rotate. The drive gears 35 drive the rotating gears 36 to rotate at the same time, and the rotating gears 36 drive a plurality of limit sliders 37 to slide inside the annular limit chute 38. While rotating, the rotating gear 36 drives the metal pipe body 2 to rotate through the arc-shaped anti-slip clamping plate 362 inside, so as to facilitate the adjustment of the position of the metal pipe body 2 during non-destructive testing, thereby improving the detection efficiency.
