The output shaft of the second servo motor 40 is fastened to the rotating rod 38. The second servo motor 40 is electrically connected to the controller 16.

[0035] The working principle of the stainless steel pipe weld testing device provided by this utility model is as follows:

[0036] By rotating bolt 6 in sequence, bolt 6 moves and adjusts the arc plates 7, allowing the two sets of arc plates 7 to accommodate stainless steel tubes of different sizes. The stainless steel tube body 17 is then placed between the two sets of arc plates 7, which clamp and fix the stainless steel tube. Next, bolt 25 is tightened in sequence, pressing against the circular plate 23. This allows the two sets of elastic first rollers 22 to firmly adhere to the outer surface of the stainless steel tube body 17. At this point, the two sets of arc plates 7 and the two sets of first rollers 22 can securely clamp the stainless steel tube from all sides, improving its stability. To test the stability of the stainless steel pipe weld, the controller 16 then starts the first servo motor 13. The output shaft of the first servo motor 13 drives the gear 15 on the rotating shaft 14 to rotate, so that the gear 15 can drive the rotating ring 4 with gear teeth 11 to rotate inside the annular groove 3. At this time, the two rotating rings 4 can drive the stainless steel pipe body 17 to rotate and adjust. This facilitates the all-round testing of the weld of the stainless steel pipe body 17 without manual operation, saving time and effort, so as to quickly test the weld of the stainless steel pipe and improve the testing efficiency of the stainless steel pipe weld testing device.

[0037] By activating the second servo motor 40, the output shaft of the second servo motor 40 drives the cam 39 on the rotating rod 38 to rotate. This allows the cam 39 to lift the third roller 35, enabling the elastic second roller 33 to fit against the underside of the stainless steel pipe body 17. This provides stable support for the stainless steel pipe and facilitates rotation testing, improving safety during weld testing. Next, the controller 16 activates the electric slide table 27. The motor on the electric slide table 27 drives the electric slider 28 to move on the electric slide table 27, moving the ultrasonic weld inspector 66 to the weld testing position. Then, the controller 16 activates the electric push rod 29, which moves the ultrasonic weld inspector 66 closer to the stainless steel pipe body 17. The controller 16 then activates the ultrasonic weld inspector 66 again, allowing its ultrasonic probe to test the weld of the stainless steel pipe. Simultaneously, the rotation of the stainless steel pipe body 17 ensures comprehensive weld testing, guaranteeing that the weld quality meets requirements.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
