[0021] Ultrasonic flaw detection equipment is widely used in industrial inspection. However, when different people are performing ultrasonic flaw detection, whether during calibration or actual measurement, the differences in the angle, force, and stability of the handheld probe lead to poor repeatability of the test data, which affects the accuracy of defect judgment.

[0022] To address the problems existing in the aforementioned related technologies, this utility model provides an ultrasonic flaw detection auxiliary device 10.

[0023] Combination Figures 1 to 5 As shown, an ultrasonic flaw detection auxiliary device 10 includes a main body 20 and a bolt portion 30. The main body 20 includes a groove 21 located at the bottom of the main body 20 and a first threaded hole 22 passing through the side wall of the main body 20 and communicating with the groove 21. The groove 21 is used to place an ultrasonic flaw detection probe. The bolt portion 30 is located on the side wall of the main body 20 and is threadedly engaged with the first threaded hole 22. By screwing it in or out, the ultrasonic flaw detection probe can be clamped or loosened.

[0024] By setting a groove 21 at the bottom of the main body 20 of the ultrasonic flaw detection auxiliary device 10, with the groove opening facing downwards, and using it to hold the ultrasonic flaw detection probe, a first threaded hole 22 is opened on the side wall of the main body 20. By using the threaded engagement of the bolt part 30 with the hole thread of the first threaded hole 22, the ultrasonic flaw detection probe can be clamped or loosened by screwing in or out, thus achieving a stable clamping of the probe. The ultrasonic flaw detection probe can extend downwards from the groove opening of the groove 21. During measurement, the ultrasonic flaw detection auxiliary device 10 and the ultrasonic flaw detection probe are set above the surface to be tested. The weight of the main body 20 is used as a downward pressure to make the probe fit tightly against the surface to be tested, reducing the problem of inconsistent downward pressure caused by differences in force when different people operate, thereby improving the stability and reliability of calibration or test results.

[0025] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 The main body 20 also includes a first wire hole 61, which penetrates the top of the main body 20 and is connected to the groove 21. The signal line or power line of the ultrasonic flaw detection probe can be led out through the first wire hole 61, avoiding interference or pulling caused by the wire swinging randomly during the detection or calibration process, while ensuring that the signal line is laid out in an orderly manner, improving the convenience and safety of operation.

[0026] Specifically, the diameter of the first wire hole 61 needs to be larger than the outer diameter of the signal line or power line to ensure that the line can pass through smoothly without being squeezed, and to avoid damage to the cable or unstable signal transmission due to friction or bending; at the same time, the edge of the hole can be rounded to prevent sharp edges from cutting the wire insulation and to ensure long-term stable operation of the equipment.

[0027] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 The main body 20 also includes a second wire hole 62 that penetrates the top of the main body 20 and communicates with the groove 21. The second wire hole 62 penetrates at least one side of the main body 20. The signal line or power line of the ultrasonic flaw detector probe can also be led out from the side of the ultrasonic flaw detector probe. If it were to pass through the first wire hole 61, the signal line or power line would need to be bent at 90°, which could easily lead to fatigue breakage of the signal line or power line. The second wire hole 62, by penetrating the top and side of the main body 20, allows the signal line or power line to be smoothly led out in an inclined direction, effectively reducing the bending angle and reducing the mechanical stress generated by repeated bending of the cable, thereby extending its service life. The second wire hole 62 and the first wire hole 61 form a dual wiring channel, which users can flexibly choose according to the output direction of the signal line or power line of the ultrasonic flaw detector probe. It can be adapted to various probes without changing the device, improving the versatility of the auxiliary device.

[0028] In some embodiments, please refer to the following for details. Figure 1 , Figure 2The ultrasonic flaw detection auxiliary device 10 also includes a counterweight 40 disposed on the top of the main body 20. Different application scenarios have different requirements for downward pressure. Sometimes, the weight of the main body 20 alone is not enough to ensure that the probe is stably attached to the detection surface. At this time, the counterweight 40 can increase the overall weight to provide additional downward pressure, ensure that the probe is in full contact with the detection surface, and improve the stability and reliability of the detection signal.

[0029] Specifically, the counterweight 40 is detachably mounted on the top of the main body 20, which allows for easy adjustment of weight according to actual needs and adaptation to different testing conditions.

[0030] In some embodiments, please refer to the following for details. Figure 1 , Figure 2 The ultrasonic flaw detection auxiliary device 10 also includes a first adhesive layer 51 disposed between the main body 20 and the counterweight 40. Compared to bolted connections, which require drilling and tightening bolts, the first adhesive layer 51 only requires peeling and pasting, making the operation simpler and allowing for quick installation or disassembly of the counterweight 40, thus improving operational efficiency. Simultaneously, the adhesive layer provides a certain buffering effect, reducing vibration transmission and avoiding stress concentration caused by rigid connections, further ensuring the stability and reliability of the equipment operation.

[0031] Specifically, the counterweight part 40 may include multiple counterweight pieces, which can be stacked and arranged. Users can flexibly add or remove them according to testing needs. Adjacent counterweight pieces can be bonded to each other in sequence through an adhesive layer to achieve precise weight adjustment. This is easy to understand and is not shown in the figure.

[0032] Specifically, the first adhesive layer 51 is made of pressure-sensitive adhesive material, which has good initial tack and holding power, and can maintain stable bonding performance under different temperature environments, ensuring that the counterweight part 40 is not easy to fall off under vibration conditions. This is only an example and is not a specific limitation.

[0033] In some embodiments, please refer to the following for details. Figure 3 The main body 20 is a ferromagnetic material, and the counterweight 40 includes a magnet part 41 near the main body 20. An attractive force is generated between the magnet part 41 and the ferromagnetic main body 20, allowing for quick installation and stable connection of the counterweight 40 without additional fasteners. It also facilitates the disassembly and replacement of counterweights 40 of different weights to meet various testing needs.

[0034] Specifically, the main body 20 can be made of a ferromagnetic metal material, such as electrical pure iron or low-alloy steel, possessing good magnetic permeability and structural strength, enabling it to form a stable magnetic attraction connection with the magnet part 41 of the counterweight part 40, ensuring that the counterweight part 40 is not prone to slippage during operation. The magnet part 41 can be made of a permanent magnet material, such as neodymium iron boron, which can provide sufficient attraction force in a small volume, ensuring that the counterweight part 40 maintains a reliable connection even under vibration. The specific material can be selected according to the actual working conditions to balance cost, weight, and magnetic performance; this is only an example and not a specific limitation.

[0035] In some embodiments, please refer to the following for details. Figure 3 The counterweight 40 further includes at least one ferromagnetic counterweight piece 42 disposed on the side of the magnet part 41 away from the main body 20. The ferromagnetic counterweight pieces 42 can be stacked one by one, and the pieces can be quickly stacked by magnetic self-attraction without the need for additional connecting structures, facilitating flexible adjustment of the overall weight to adapt to different downward pressure requirements. By increasing or decreasing the number of ferromagnetic counterweight pieces 42, fine-tuning of the weight can be achieved without replacing the entire counterweight 40, improving the applicability and ease of operation of the device.

[0036] Specifically, the ferromagnetic counterweight 42 can be made of stainless steel or cast iron, which has good quality stability and corrosion resistance, ensuring that it is not easily deformed or rusted during long-term use. This is just an example and is not a specific limitation.

[0037] For details, please refer to [link / reference]. Figures 1 to 5 The counterweight 40, the first adhesive layer 51, and the magnet 41 have clearance through holes 23 that match the first wire hole 61 and the second wire hole 62, so as to allow the wires to pass through and be led out to the external control system, and avoid wiring interference or squeezing damage caused by the counterweight 40 blocking the cable channel.

[0038] In some embodiments, please refer to the following for details. Figure 2 A buffer layer 70 is also provided on the end of the bolt part 30 near the center of the groove 21. When the bolt part 30 is rotated to clamp the ultrasonic flaw detection probe, the metal bolt part 30 is prone to scratching the probe shell. The flexibility of the buffer layer 70 can disperse the clamping force, avoid excessive local pressure that may cause deformation of the shell, ensure the probe performance is intact, and reduce the deviation of detection data caused by probe damage.

[0039] Specifically, the buffer layer 70 can be made of elastic materials such as rubber, silicone or polyurethane, which has good resilience and wear resistance. At the same time, the buffer layer 70 has excellent friction properties, which can effectively increase the friction with the probe housing and prevent the clamping from loosening. This is only an example and is not a specific limitation.

[0040] In some embodiments, please refer to the following for details. Figure 4The ultrasonic flaw detection auxiliary device 10 also includes a second adhesive layer 52 disposed at the bottom of the tank 21. Even if the bolt portion 30 clamps the ultrasonic flaw detection probe, the top of the ultrasonic flaw detection probe and the bottom of the tank 21 may still experience slight slippage due to the relatively small coefficient of friction, affecting the detection stability. The second adhesive layer 52 fixes the top of the ultrasonic flaw detection probe with adhesiveness, further improving the stability of the probe during the detection process.

[0041] Specifically, the area and position of the second adhesive layer 52 can be adapted to the size and shape of the ultrasonic flaw detector probe to ensure effective bonding without affecting the installation and disassembly of the probe. The adhesive area in the figure is only an example and is not intended as a basis for actual limitation.

[0042] Specifically, the second adhesive layer 52 can be made of pressure-sensitive adhesive or silicone-based adhesive material, which has moderate adhesion and reusability. It can firmly fix the probe without leaving residue or damaging the probe surface during disassembly. This is only an example and is not a specific limitation.

[0043] In some embodiments, please refer to the following for details. Figure 5 The bottom of the groove 21 is provided with a plurality of first protrusions 80. The plurality of first protrusions 80 increase the roughness of the bottom of the groove 21, thereby increasing the frictional resistance with the top of the ultrasonic flaw detection probe, effectively suppressing the slippage of the probe caused by vibration or tilting force during the detection process, and preventing the probe from sliding even without the second adhesive layer 52, thus ensuring stability.

[0044] Specifically, the number and pattern of the first protrusions 80 can be adjusted according to the actual probe shape and contact surface characteristics, and can be distributed in an array or arranged irregularly. The first protrusions 80 shown in the figure can be cylindrical, conical, hemispherical or truncated pyramidal structures. This is only an example and is not specifically limited.

[0045] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
