[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1:

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a high-precision metal non-destructive testing instrument, including a mounting base 1. A slot 11 is formed at the top of the mounting base 1, and a metal cover 15 is engaged inside the slot 11. An iron oxide film 14 is fixedly installed on the outside of the metal cover 15. An electric telescopic rod 20 is fixedly installed on the top of the mounting base 1. A side plate 13 is fixedly installed at the output end of the electric telescopic rod 20 and is fixedly connected to the metal cover 15. An adjustment box 2 is fixedly installed on the top of the mounting base 1. A rotating shaft 18 is rotatably connected to the top of the adjustment box 2. A rotating roller 9 is fixedly sleeved on the outside of the rotating shaft 18. One side of the adjustment box 2... A second motor 17 is fixedly installed, and its output end is fixedly connected to one end of a rotating shaft 18. A mounting groove 7 is provided on the top of the mounting base 1, and a slider 4 is slidably connected inside the mounting groove 7. A movable box 8 is fixedly installed on the top of the slider 4, and a detector 6 is fixedly installed inside the movable box 8. A probe 3 is provided on the top of the movable box 8, and the detector 6 is electrically connected to the probe 3. The detector 6 can be an ultrasonic non-destructive testing instrument or an electromagnetic ultrasonic flaw detector, as needed. The ultrasonic non-destructive testing instrument model can be a ZT301 type metal ultrasonic flaw detector. A first motor 16 is fixedly installed on one side of the mounting base 1. The mounting groove 7... A lead screw 5 is rotatably connected to the slide block 4, passing through it and threadedly connected to the slide block 4. The output end of the first motor 16 is fixedly connected to one end of the lead screw 5. A limit groove 21 is formed inside the metal cover 15. A limit bolt 12 is threadedly connected inside the mounting base 1. One end of the limit bolt 12 is fixedly connected to a limit block 10, which is adapted to the limit groove 21. By using the electric telescopic rod 20 to drive the side plate 13 to move, the metal cover 15 can be inserted into the slot 11, thus completing the installation of the metal cover 15. The limit bolt 12 threaded connection can complete the limiting work of the metal cover 15. The materials of the metal shield 15 and the iron oxide film 14 can shield electromagnetic signals, thereby improving the accuracy of data during detection. The second motor 17 drives the rotating shaft 18 to rotate, which in turn moves the outer rotating roller 9. The rotating roller 9 can adjust the angle of the top metal pipe. The first motor 16 drives the lead screw 5 to rotate, which in turn moves the slider 4. The movement of the slider 4 moves the detector 6, which can then use the probe 3 to detect the material, thus completing the detection work. The detector can adjust its position autonomously, improving its practicality.

[0020] In summary, this high-precision metal non-destructive testing instrument is used by first placing the metal pipe on top of the rotating roller 9, then using the electric telescopic rod 20 to move the side plate 13, which inserts the metal cover 15 into the slot 11, thus completing the installation of the metal cover 15. The metal cover 15 is then limited by the threaded connection of the limit bolt 12. After the limit is completed, the second motor 17 drives the rotating shaft 18 to rotate, which in turn moves the outer rotating roller 9. The angle of the top metal pipe can be adjusted using the rotating roller 9. During the adjustment process, the first motor 16 drives the lead screw 5 to rotate, which in turn moves the slider 4, which in turn moves the testing instrument 6. The probe 3 is then used to test the material. During testing, a coupling agent can be applied manually as needed to assist the operation, thus completing the testing work.
