Description

Technical Field

[0001] This utility model relates to the field of weld penetration measurement technology, specifically a weld penetration measurement device for welding. Background Technology

[0002] As a critical component connecting metal structures, the weld penetration depth is a core indicator of weld quality, directly affecting the strength, sealing performance, and fatigue life of the welded joint. In fields such as machinery manufacturing, petrochemicals, and bridge construction, welds must withstand various loads including tension, bending, and impact. Insufficient penetration depth can lead to reduced joint load-bearing capacity, making it prone to cracking and leakage. Conversely, excessive penetration depth can cause overheating of the base material, resulting in coarse grains and reduced toughness, similarly impacting the overall performance of the component. Therefore, accurately measuring weld penetration depth is crucial for ensuring weld quality meets design standards and guaranteeing the safe operation of the structure.

[0003] For example, Chinese utility model patent application number 202021058961.5 discloses an ultrasonic weld penetration measurement device. In use, pushing a slider via a connecting rod causes the ultrasonic probe to extend and probe the weld location. This avoids accidental collisions between surrounding objects and the ultrasonic probe during detection, preventing damage that would delay work and increase the company's financial burden. However, this device still has certain shortcomings. In actual use, ultrasonic probes are connected to the equipment via cables, which are inconvenient to store. After testing, if the cables are piled up haphazardly, they may become tangled or excessively bent, requiring time to organize them for the next use and reducing work efficiency. Furthermore, cable damage caused by long-term irregular storage will increase equipment maintenance costs and may even affect the testing progress due to sudden malfunctions.

[0004] Therefore, we propose a weld penetration measurement device for welding to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a weld penetration measurement device for welding, in order to solve the problems mentioned in the background art. Currently, ultrasonic probes on the market are connected to the equipment via connecting cables in actual use, which is inconvenient to store. After the test is completed, if the connecting cables are piled up randomly, they may become knotted or excessively bent, requiring time to organize them for the next use and reducing work efficiency. Furthermore, cable damage caused by long-term irregular storage will increase equipment maintenance costs and may even affect the testing progress due to sudden failures.

[0010] With the above structural design, the arc-shaped sleeve is located directly above the limiting post. The protective limiting block inside it squeezes the coiled connecting line when the arc-shaped sleeve descends. At the same time, the arc-shaped sleeve is fitted over the outside of the connecting line. The double limiting prevents the connecting line from loosening and avoids knotting or damage. The protective limiting block is elastic and will not damage the connecting line. The arc-shaped sleeve is fitted over the outside of the connecting line and is close to the connecting line, but does not squeeze the connecting line.

[0011] Preferably, guide rods are installed on both the left and right sides of the upper surface of the arc-shaped sleeve, the guide rods pass through the top plate, and the guide rods are slidably connected to the top plate.

[0012] With the above structural design, the guide rod on the arc-shaped sleeve passes through the top plate and slides, restricting the rotation of the arc-shaped sleeve and ensuring that it rises and falls smoothly along a straight line, accurately aligning with the connecting line on the limit post to ensure the limiting effect.

[0013] Preferably, the upper surface of the arc-shaped sleeve is equipped with multi-stage guide telescopic rods on both the left and right sides, and the upper ends of the multi-stage guide telescopic rods are connected to the lower surface of the top plate.

[0014] With the above structural design, the multi-stage guide telescopic rod between the arc sleeve and the top plate extends and retracts synchronously with the rise and fall of the arc sleeve, providing auxiliary support for the arc sleeve, enhancing its stability during the rising and falling process, and avoiding the impact of shaking on the limiting accuracy of the connecting line.

[0015] Preferably, the measuring probe assembly includes a connecting component, an ultrasonic measuring probe, and a connecting wire. The ultrasonic measuring probe is installed below the connecting component, and the connecting wire is installed above the connecting component.

Then, the fastening nut is tightened to fix the position, thereby storing the ultrasonic measuring probe in the protective box to prevent damage to the ultrasonic measuring probe.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the weld penetration measurement device for welding: 1. Achieve organized storage of connecting cables, improving equipment efficiency and lifespan. After the measurement is completed, the connecting wire can be wound up on the limiting post. The threaded rod on the rotating top plate drives the arc sleeve to descend.

Furthermore, an arc-shaped sleeve 9 is installed below the threaded rod 7 via a bearing seat 8. The arc-shaped sleeve 9 is located directly above the limiting post 6. A protective limiting block 10 is installed inside the arc-shaped sleeve 9. When the arc-shaped sleeve 9 descends, the protective limiting block 10 squeezes the coiled connecting wire 1303. At the same time, the arc-shaped sleeve 9 fits over the outside of the connecting wire 1303, providing double limiting to prevent the connecting wire 1303 from loosening, tangling, or being damaged.

The arc-shaped sleeve 9 is close to the connecting line 1303 but does not compress it. Guide rods 11 are installed on both the left and right sides of the upper surface of the arc-shaped sleeve 9. The guide rods 11 penetrate the top plate 4 and are slidably connected to the top plate 4. The guide rods 11 on the arc-shaped sleeve 9 penetrate the top plate 4 and slide, restricting the rotation of the arc-shaped sleeve 9 and ensuring its smooth, linear rise and fall, accurately aligning with the connecting line 1303 on the limiting post 6, thus ensuring the limiting effect. A measuring probe assembly 13 is located on the left side of the main body 2 of the measuring device. The measuring probe assembly 13 includes a connecting component 1301, an ultrasonic measuring probe 1302, and a connecting cable 1303. The ultrasonic measuring probe 1302 is mounted below the connecting component 1301, and the connecting cable 1303 is mounted above the connecting component 1301. The connecting cable 1303 is connected to the main body 2 of the measuring device and is wound up on a limiting post 6. The ultrasonic measuring probe 1302 of the measuring probe assembly 13 is connected to the connecting cable 1303 through the connecting component 1301.

The measurement signal is transmitted to the main body 2 of the measuring equipment through the connecting line 1303, and the weld penetration data is displayed on the display 3 on the front surface.

[0027] After the measurement is completed, the connecting wire 1303 is rewound onto the limiting post 6, and the threaded rod 7 is rotated in the opposite direction to make the arc sleeve 9 descend.
