[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figure 1 and Figure 2 As shown, a welding verification device includes: a base frame 20, which is a U-shaped rod with the opening facing upwards. Motors 21 are symmetrically fixed to both sides of the outer wall of the base frame 20. A detection head 26 is provided in the opening of the base frame 20. The base frame 20 is mounted on a machine tool. The motors 21 are electrically connected to the corresponding power supply. The detection head 26 uses the model HD8-0020W, which is existing technology and will not be described in detail here.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the rotating test structure is set on the wall of the base frame 20 for inspecting the weld joint. The rotating test structure includes: a control shaft 22, a limiting block 23, a rotating ring 24, and an extension plate 25. The control shaft 22 is symmetrically rotated and connected within the opening of the base frame 20. The limiting blocks 23 are symmetrically arranged within the opening of the base frame 20. The rotating ring 24 is rotatably connected between each set of symmetrical limiting blocks 23. The extension plate 25 is symmetrically fixedly connected to the wall of each rotating ring 24. The detection head 26 is fixedly connected to the wall of the extension plate 25. The rotating ring 24 can rotate on the wall of the limiting block 23.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the control shaft 22 is cylindrical, and teeth are formed on its arc surface. The motor 21 can drive the control shaft 22 to rotate. The rotating ring 24 is annular, and teeth that can mesh with the wall surface of the control shaft 22 are formed on its inner wall surface. A notch is formed at the top of the rotating ring 24. The limiting block 23 is a block with a concave cross-section. The opening of the limiting block 23 is arc-shaped, and the opening of the limiting block 23 can engage with the inner arc surface of the rotating ring 24. The extension plate 25 is a rectangular plate, and the same detection head 26 is installed on the wall surface of each extension plate 25. The top of the base frame 20 is provided with a clamping structure, which includes: an upper plate 30, a slide groove 31, a slider 32, and a slide rail 33. The upper plate 30 is symmetrically fixed at both ends of the top of the base frame 20. The slide groove 31 is formed in each upper plate 30. At the top, symmetrical limiting blocks 23 on each side are fixedly connected to the side wall of the upper plate 30. Slider 32 is slidably connected in each slide groove 31. Slide rail 33 is fixedly connected to the top of each slider 32. The slide groove 31 can adapt to the sliding of slider 32. Slider 32 is a convex block. Slide rail 33 is an upward-opening U-shaped frame. The clamping structure also includes a rotating shaft 34, clamping plate 35, side blocks 36, convex plate 37 and top plate 38. The rotating shaft 34 is rotatably connected in the opening of each slide rail 33. The clamping plate 35 is slidably connected in the top opening of each slide rail 33. The side blocks 36 are symmetrically fixedly connected on both sides of the wall of each clamping plate 35. The convex plate 37 is fixedly connected between each set of symmetrical side blocks 36. The top plate 38 is symmetrically fixedly connected to the top of each clamping plate 35.

[0030] In practical use, first, the opening of the symmetrical rotating ring 24 faces upward. Then, the weld to be inspected is placed on top of the symmetrical upper plate 30 from the opening of the symmetrical rotating ring 24. At this time, the weld is adjusted to be located between the symmetrical inspection heads 26 on each side. Then, the rotating shaft 34 is rotated. As the rotating shaft 34 rotates, the symmetrical clamping plates 35 can move towards each other. Then, the clamping plates 35 drive the protruding plate 37, side block 36, and top plate 38 to clamp the workpiece on the top of the upper plate 30. After the workpiece is clamped, the power is turned on, and the motor 21 can be turned on. The control shaft 22 is driven to rotate, and when the control shaft 22 rotates, it drives the rotating ring 24 to rotate along the opening of the limiting block 23 through the meshing teeth on its wall. As the rotating ring 24 rotates, it drives the extension plate 25 and the detection head 26 to rotate around the weld. As the detection head 26 rotates, the weld can be verified and detected, and the detection data will be displayed on the machine tool display screen. After the detection is completed, the rotating ring 24 will rotate back to the state with the opening facing upward. At this time, the control symmetrical clamping plate 35 will release the clamping of the workpiece, and then the workpiece that has been detected can be removed.

[0031] In summary, by setting up a rotating testing structure, the rotating ring 24 drives the detection head 26 to perform annular detection on the weld joint of the workpiece. Therefore, this solution does not have a blind spot in the detection scan, thus providing more accurate detection data.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the rotating shaft 34 is cylindrical, and the arc surface of the rotating shaft 34 is provided with opposing threads. The diameter of the middle section of the rotating shaft 34 is smaller than that of the two sides. The rotating shaft 34 can pass through the wall of the clamping plate 35 and be threadedly connected to the clamping plate 35. The clamping plate 35 is a rectangular plate, and the side block 36 is a rectangular block. The side block 36 is located on the wall surface of the symmetrical clamping plate 35 on each side facing each other. The convex plate 37 is a semi-circular block, and the top plate 38 is also a semi-circular block. The side block 36, the convex plate 37 and the top plate 38 are all made of rubber.

[0033] In actual use, the rotating shaft 34 rotates, and as the rotating shaft 34 rotates, the symmetrical clamping plates 35 can move towards each other. Then the clamping plates 35 drive the convex plate 37, the side block 36 and the top plate 38 to clamp the workpiece on the top of the upper plate 30.

[0034] In summary, by setting up a clamping structure, the side block 36, the convex plate 37 and the top plate 38 can be adapted to different workpiece sizes and shapes. Furthermore, the rubber material will not damage the workpiece during clamping. When inspecting the workpiece, the slide rail 33 is pushed to drive the slider 32 to slide along the slide groove 31 to inspect both sides of the weld.

[0035] Working principle: First, the opening of the symmetrical rotating ring 24 is facing upwards. Then, the weld to be inspected is placed on top of the symmetrical upper plate 30 from the opening of the symmetrical rotating ring 24. At this time, the weld is adjusted to be located between the symmetrical inspection heads 26 on each side. Then, the rotating shaft 34 is rotated. As the rotating shaft 34 rotates, the symmetrical clamping plates 35 can move towards each other. Then, the clamping plates 35 drive the protruding plate 37, side block 36, and top plate 38 to clamp the workpiece on the top of the upper plate 30. After the workpiece is clamped, the power is turned on. The motor 21 can start when the power is turned on. The drive control shaft 22 rotates, and when the control shaft 22 rotates, it drives the rotating ring 24 to rotate along the opening of the limiting block 23 through the meshing teeth on its wall. As the rotating ring 24 rotates, it drives the extension plate 25 and the detection head 26 to rotate around the weld. As the detection head 26 rotates, the weld can be verified and detected, and the detection data will be displayed on the machine tool display screen. After the detection is completed, the rotating ring 24 will rotate back to the state with the opening facing upward. At this time, the control symmetrical clamping plate 35 will release the clamping of the workpiece, and then the workpiece that has been detected can be removed.
