[0025] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0026] Example 1

[0027] refer to Figure 1 and Figure 2, including a welding part 1, a flaw detector body 2 and a test platform 3. A welding support assembly 4 is provided on the top of the test platform 3 near both sides for supporting the positioning assembly 5. The welding part 1 is lifted up by the positioning assembly 5 to keep it away from the test platform 3. The welding support assembly 4 includes a welding support cylinder 19, a first spring member 20, a fixing bolt 21 and a welding support rod 22. The welding support cylinder 19 is fixed to the top of the movable plate 18. The first spring member 20 and the welding support rod 22 are both movable inside the welding support cylinder 19. It should be noted that the shape of the welding support rod 22 inside the welding support cylinder 19 is non-circular. In this embodiment, it is a hexagonal design. The shape of the inner wall of the welding fixing cylinder matches the shape of the welding support rod 22 at this position, so as to prevent the welding support rod 22 from rotating inside the welding support cylinder 19. The welding support rod 22 The top of the welding support rod 22 is movably connected to the top of the first spring member 20, and the top of the welding support rod 22 passes through the welding support tube 19 and is fixed to the side of the fixed outer ring 6. This position structure mainly sets up the positioning assembly 5. When it is necessary to adjust the height of the positioning assembly 5, it is first necessary to rotate the fixing bolt 21 to separate it from the welding support rod 22, and then move the welding support rod 22 up and down to squeeze the first spring member 20. It should be noted that the first spring member 20 is used to facilitate the up and down movement of the welding support rod 22, avoiding the need for a large force to lift the welding support rod 22 and the components on the welding support rod 22. After the welding support rod 22 reaches the appropriate position, the fixing bolt 21 is rotated in the opposite direction to position the welding support rod 22. This operation mainly adjusts the height of the positioning assembly 5, so that welding parts 1 of different sizes are brought close to the flaw detector body 2, thereby improving the detection accuracy.

[0028] The top of the welding support assembly 4 is provided with a positioning assembly 5, which includes a fixed outer ring 6 and a rotating inner ring 7. The fixed outer ring 6 is fixed to the top of the welding support rod 22. When the position is fixed, the fixed position needs to be staggered with the clamping assembly to avoid limited rotation of the clamping assembly. The rotating inner ring 7 is rotatably connected to the inner side of the fixed outer ring 6 through a bearing, so that the rotating inner ring 7 can rotate stably on the fixed outer ring 6. A power assembly 8 is provided on the rotating inner ring 7, which includes a drive motor 9, a drive gear 10 and an annular tooth groove 11. The drive motor 9 also needs to be staggered with the clamping assembly so that it does not affect the rotation of the clamping assembly. The annular tooth groove 11 is provided on the side of the rotating inner ring 7 close to the flaw detector body 2. The drive gear 10 is connected to the inner ring 7. The annular tooth groove 11 is engaged, the drive motor 9 is fixed on the welding support assembly 4, and the drive gear 10 is fixedly sleeved on the output shaft of the drive motor 9. The other side of the power assembly 8 is set on the welding support assembly 4. During operation, it is necessary to first fix the weldment 1 through the clamping assembly, and then start the drive motor 9 in the power assembly 8. The drive motor 9 starts to drive the drive gear 10 to rotate. The rotation of the drive gear 10 drives the annular tooth groove 11 to rotate. The rotation of the annular tooth groove 11 drives the rotating inner ring 7 to rotate on the fixed outer ring 6, so that the rotating inner ring 7 rotates through the clamping assembly to drive the weldment 1 to rotate, which will rotate the welding position. The welding position rotates through the flaw detector body 2, thereby achieving the purpose of rotating the weldment 1 for rapid detection;

[0029] refer to Figure 1 and Figure 2 , the positioning assembly 5 is provided with a clamping assembly, which includes a clamping rod 32 and a movable head 33. The clamping rod 32 is rotatably connected to the rotating inner ring 7 at a position staggered from the fixed outer ring 6. The movable head 33 is movably sleeved on one end of the clamping rod 32 located on the inner side of the positioning assembly 5. The movable head 33 fits tightly against the surface of the weldment 1. During operation, the weldment 1 is first inserted into the rotating inner ring 7 and located between the clamping rods 32. It should be noted here that there are three groups of clamping rods 32, and the three groups of clamping rods 32 are arranged in an array on the rotating inner ring 7. Then, the three groups of clamping rods 32 are rotated to stably clamp the weldment 1. At this time, the weld on the weldment 1 is located just above the flaw detector body 2;

[0030] refer to Figure 2 and Figure 3The top of the monitoring platform is provided with a detection support assembly, which includes a detection fixed cylinder 27, a detection support rod 28, a second spring member 29, a mounting plate 30 and a pulley 31. The detection fixed cylinder 27 is fixed to the top of the movable block 25. The detection support rod 28 and the second spring member 29 are both movable inside the detection fixed cylinder 27. The bottom end of the detection support rod 28 is movably connected with the top end of the second spring member 29. The top end of the detection support rod 28 passes through the detection fixed cylinder 27 and extends to the top of the detection fixed cylinder 27 and is fixed to the mounting plate 30. The flaw detector body 2 is provided on the mounting plate 30. The pulley 31 is also installed on the mounting plate 30 and is offset from the position of the flaw detector body 2. The height of the pulley 31 is higher than the height of the flaw detector body 2. There are two groups of pulleys 31. The two groups of pulleys 31 are axially symmetrically arranged with the flaw detector body 2 as the symmetry axis. The flaw detector body 2 is provided at the top position of the monitoring support assembly. The detection position of the flaw detector body 2 is set near the welding position on the welded part 1. During operation, the welded part 1 rotates When the weld 1 is rotated, the second spring member 29 pushes the detection support rod 28 upward, and the detection support rod 28 pushes the mounting plate 30, the flaw detector body 2 and the two sets of pulleys 31 upward. At this time, the pulleys 31 roll on the surface of the weld 1. The rotation of the weld 1 drives the pulleys 31 to roll on the weld 1. When encountering a concave surface on the weld 1, the second spring member 29 pushes the flaw detector body 2 and the pulleys 31 through the detection support rod 28 and the mounting plate 30, so that the pulleys 31 remain stably attached to the surface of the weld 1, and the distance between the flaw detector body 2 and the weld 1 remains the same. When encountering a convex surface of the weld 1, the pulleys 31 press the second spring member 29 through the mounting plate 30 and the detection support rod 28, causing the second spring member 29 to contract. This operation ensures that the distance between the flaw detector body 2 and the surface of the weld 1 is always consistent during use, improving detection accuracy. In addition, the detection support assembly supports the flaw detector body 2, eliminating the need for manual operation by the operator, reducing fatigue and increasing detection efficiency.

[0031] Example 2

[0032] refer to Figure 1 、 Figure 2 and Figure 3, the bottom of the welding support assembly 4 is provided with a first adjusting assembly 12, and the first adjusting assembly 12 is arranged on the top of the detection platform 3. The first adjusting assembly 12 includes two welding guide grooves 13, an adjusting groove 14, two guide blocks 15, an adjusting block 16 and an adjusting rod 17. The two welding guide grooves 13 and the adjusting groove 14 are fixed on the top of the detection platform 3 near the end surface. The two welding guide grooves 13 are axially symmetrical with the adjusting groove 14 as the symmetry axis. The two guide blocks 15 are movable in the two welding guide grooves 13, and the adjusting block 16 is movable in the adjusting groove 14. The adjusting rod 17 is rotatably connected to the inside of the adjusting groove 14 through a bearing. The adjusting block 16 is threaded on the surface of the adjusting rod 17. A movable plate 18 is fixed on the top of the two guide blocks 15 and the adjusting block 16, and the welding support assembly 4 is fixed on the movable plate. The top of the movable plate 18, it should be noted that this position structure needs to be operated before the weldment 1 is clamped, and adjusted according to the actual size of the weldment 1. If the weldment 1 is large, the adjusting rod 17 is rotated to drive the adjusting block 16 to move away from the flaw detector body 2 to increase the distance between the two sets of welding support assemblies 4 and the positioning assembly 5, so that the larger weldment 1 can be clamped. Conversely, the adjusting rod 17 is rotated in the opposite direction to shorten the distance between the two sets of welding support assemblies 4 and the positioning assembly 5, thereby achieving the effect of clamping weldments 1 of different sizes. It should be noted that even if different clamping assemblies are clamped, a clamping effect will be achieved when the distance between the two rotating assemblies is shortened. In this way, the weldment 1 can be clamped from the side of the weldment 1, providing multiple clamping methods to clamp the weldment 1, thereby improving its practicality.

[0033] refer to Figure 2 and Figure 3 A detection adjustment assembly 23 is provided at the bottom of the detection support assembly. The detection adjustment assembly 23 is provided on the top of the detection platform 3 and is located on the symmetrical axis of the detection platform 3. The detection adjustment assembly 23 includes a detection guide groove body 24, a movable block 25 and a threaded rod 26. The detection guide groove body 24 is fixed to the top of the detection platform 3. The movable block 25 moves inside the detection guide groove body 24. The threaded rod 26 is rotatably connected to the inside of the detection guide groove body 24 through a bearing. The movable block 25 is threadedly sleeved on the surface of the threaded rod 26. During operation, the threaded rod 26 needs to be rotated to drive the movable block 25 to move. The movement of the movable block 25 will drive the detection support assembly to move, thereby changing the position of the flaw detector body 2 to match different welding positions.
