In this embodiment, the personnel align the hexagonal nut of the bolt through the clamping block 9 of the adjusting rod 7 on the two support frames 4, and then rotate the threaded column 6 of the threaded hole on the two support frames 4, and the threaded column 6 drives the bearing 8 to rotate The adjusting rod 7 is slidably connected to the slot 5 through the bearing 8 and the adjusting rod 7, so that the adjusting rod 7 can move with the bearing 8, but not with the rotation angle of the threaded column 6. The adjusting rod 7 drives the clamping block 9 to move, so that the clamping block 9 is against the hexagonal nut of the bolt. The two clamping blocks 9 fix the sliding ring 3. Then the personnel pushes the ultrasonic probe 2, and the sliding bar 10 of the guide mechanism passes through the sliding groove 11 of the sliding ring 3, so that the ultrasonic probe 2 can move linearly on the sliding ring 3. The ultrasonic probe 2 can be accurately docked on the bolt, and then the ultrasonic probe 2 is used through the controller 1 to perform flaw detection positioning. The operation is completed. After completion, the two clamping blocks 9 can be separated from the hexagonal nut by rotating the threaded column 6 in the opposite direction, so that the ultrasonic probe 2 can be retrieved. This structure can accurately assemble and dock the ultrasonic probe 2 on the bolt, and can prevent the ultrasonic probe 2 from being loosely fixed or shaking due to external shaking when the ultrasonic probe 2 is in operation, thereby ensuring that the ultrasonic probe 2 is stably docked on the bolt, so that the ultrasonic probe 2 can perform stable and reliable flaw detection positioning operations, thereby improving the flaw detection efficiency and stability of the ultrasonic probe 2. There is no need for personnel to manually hold it, and the flaw detection operation can be automatically performed after the ultrasonic probe 2 is docked.

[0024] In this solution, two guide mechanisms are provided and are symmetrically arranged. By providing two guide mechanisms that are symmetrically arranged, the ultrasonic probe 2 can move linearly on the sliding ring 3 more stably.

[0025] In this solution, a limiting ring 12 is provided on the ultrasonic probe 2, and the limiting ring 12 abuts against one end of the slide bar 10. The limiting ring 12 can limit the slide ring 3 to prevent the slide ring 3 from detaching from the slide bar 10 when adjusting the position in one direction.

More stable linear movement, two limit rings 12 are symmetrically arranged, which can ensure that the sliding ring 3 will not fall off the sliding bar 10. By rotating the limit ring 12, the sliding ring 3 can be easily disassembled, thereby facilitating the maintenance of the ultrasonic probe 2. The T-shaped slide groove 11 and the sliding bar 10 can make the sliding ring 3 move more stably in a straight line on the ultrasonic probe 2. The anti-slip groove on the outside of the clamping block 9 can improve the anti-slip performance of the clamping block 9, so that it can be clamped on the hexagonal nut of the bolt more stably. The screw block 13 can be used to hold the rotating threaded column 6. This structure can accurately assemble and dock the ultrasonic probe 2 on the bolt, and can prevent the ultrasonic probe 2 from being affected by external shaking and the like when the ultrasonic probe 2 is in operation, resulting in loose fixation and shaking, ensuring that the ultrasonic probe 2 is stably docked on the bolt, so that the ultrasonic probe 2 can perform stable and reliable flaw detection positioning operations, improve the flaw detection efficiency and stability of the ultrasonic probe 2, and does not require manual support by personnel.
