AI Technical Summary
[0003]然而,现有的超声波检测设备存在探头结构适配性差的缺陷,普通超声波检测设备的探头楔块多采用胶粘、螺纹紧固或单一卡槽插拔结构,更换不同角度楔块时需借助工具剥离残胶或旋拧螺栓,操作繁琐且耗时较长,难以适配方舱焊缝等批量检测场景下快速切换检测角度的需求,但仅依靠卡槽与楔块的过盈配合实现固定,在检测过程中受工件表面振动、探头移动摩擦等因素影响,楔块易出现松动、移位,导致超声波折射角度偏移,进而造成缺陷定位误差增大,甚至引发漏检风险
[0011]与现有技术相比,本实用新型所达到的有益效果是:本实用新型,通过设置通过T型槽与导向斜面的配合,楔块插条可快速对准插入,无需复杂对位操作;通过借助滑道与挡板的滑动结构,仅需上下移动挡板并拧动螺钉,即可完成楔块的限位或解锁,相比传统胶粘、螺纹紧固方式,缩短楔块的更换时间,提高生产效率;挡板下移后,螺纹孔一与螺纹孔二通过螺钉锁死,可对楔块插条形成刚性阻挡;同时螺纹孔三的螺钉可进一步压紧插条,结合T 型槽的防脱结构,双重约束有效避免了检测过程中楔块因振动、摩擦产生的松动、移位问题。

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of weld inspection technology, and specifically relates to a weld inspection device. Background Technology
[0002] Prefabricated shelters are typically constructed by welding metal frames and skins. In the production of prefabricated shelters, weld inspection is of paramount importance, as it directly affects the structural strength, sealing, waterproofing and rust prevention capabilities, and long-term reliability of the shelter. Weld inspection equipment is a tool used to detect surface or internal defects in welds (such as cracks, porosity, incomplete penetration, slag inclusions, etc.) and to assess whether they meet relevant quality standards.
[0003] However, existing ultrasonic testing equipment suffers from poor probe structure adaptability. Ordinary ultrasonic testing equipment often uses adhesive, threaded fastening, or a single slot-type plug-in structure for the probe wedges. Changing wedges to different angles requires tools to remove residual adhesive or tighten bolts, a cumbersome and time-consuming process that is unsuitable for the rapid angle switching needs of batch testing scenarios such as weld seams in container houses. Furthermore, relying solely on the interference fit between the slot and the wedge for fixation makes it susceptible to loosening and displacement during testing due to factors such as workpiece surface vibration and probe movement friction. This leads to a shift in the ultrasonic refraction angle, increasing defect location errors and even increasing the risk of missed detections. Therefore, this phenomenon has become a problem urgently needing to be solved by those in the field. Utility Model Content
[0004] The purpose of this invention is to provide a weld inspection device to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a weld inspection device, including a probe body, two slides fixedly connected to one side of the probe body, baffles slidably connected inside the two slides, threaded hole one and threaded hole three opened on the baffles, threaded hole two opened on one side of the probe body, and a wedge block is provided below the probe body. When the baffle needs to limit the wedge block, screws are bolted inside threaded hole one and threaded hole two. When the baffle does not need to limit the wedge block, threaded hole three and threaded hole two are threadedly connected to the screws.
[0006] The present invention further explains that the threaded hole one and the threaded hole three are arranged vertically, with the threaded hole one located above the threaded hole three, and the diameters of the threaded hole one, the threaded hole two, and the threaded hole three are equal.
[0007] The present invention further describes that a T-shaped groove is provided below the probe body, the T-shaped groove does not penetrate the probe body, and an insert is provided on the wedge block that is adapted to the T-shaped groove, and the inside of the T-shaped groove is slidably connected to the wedge block.
[0008] This utility model further explains that the T-slot is provided with a guide slope on the side near the second threaded hole, which facilitates the quick insertion of the insert on the wedge block and avoids alignment deviation.
[0009] The present invention further explains that a limiting groove is provided on the side of the slide away from the baffle. The limiting groove does not penetrate the slide. Limiting blocks are provided on both sides of the baffle, and the limiting blocks are slidably connected to the limiting groove.
[0010] The present invention further describes that a cable is provided above the probe body, a flaw detector is provided at the other end of the cable, and a display screen is provided above the flaw detector to display the detected amplitude curve.
[0011] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: By setting a T-slot and a guide slope, the wedge insert can be quickly aligned and inserted without complicated alignment operations; by using the sliding structure of the slide and the baffle, the wedge can be limited or unlocked simply by moving the baffle up and down and turning the screw. Compared with the traditional adhesive and threaded fastening methods, the replacement time of the wedge is shortened and the production efficiency is improved; after the baffle moves down, the first and second threaded holes are locked by screws, which can form a rigid block for the wedge insert; at the same time, the screw in the third threaded hole can further press the insert, and combined with the anti-loosening structure of the T-slot, the double constraint effectively avoids the problem of loosening and displacement of the wedge due to vibration and friction during the testing process.

[0013] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0014] Please see Figure 1-7 The present invention provides a technical solution: a weld inspection device, comprising a probe body 3, two slide rails 6 fixedly connected to one side of the probe body 3, a baffle 4 slidably connected inside the two slide rails 6, a threaded hole 5 and a threaded hole 10 on the baffle 4, a threaded hole 9 on one side of the probe body 3, and a wedge (not shown in the figure) provided below the probe body 3. When the baffle 4 needs to limit the wedge, a screw 7 is bolted inside the threaded hole 5 and the threaded hole 9. When the baffle 4 does not need to limit the wedge, the threaded hole 10 and the threaded hole 9 are threadedly connected to the screw 7.
[0015] Threaded hole 15 and threaded hole 30 are set vertically, with threaded hole 15 located above threaded hole 30. The diameters of threaded hole 15, threaded hole 29 and threaded hole 30 are equal.
[0016] A T-shaped groove 8 is provided below the probe body 3. The T-shaped groove 8 does not penetrate the probe body 3. An insert is provided on the wedge block that is compatible with the T-shaped groove 8. The inside of the T-shaped groove 8 is slidably connected to the wedge block.
[0017] The T-slot 8 has a guide slope 11 on the side near the threaded hole 9, which facilitates the quick insertion of the insert on the wedge block and avoids alignment deviation.
[0018] A limiting groove 12 is provided on the side of the slide 6 away from the baffle 4. The limiting groove 12 does not penetrate the slide 6. Limiting blocks 13 are provided on both sides of the baffle 4. The limiting blocks 13 are slidably connected to the limiting groove 12.
[0019] A cable 2 is installed above the probe body 3, and a flaw detector 1 is installed at the other end of the cable 2. A display screen is installed above the flaw detector 1 to display the detected amplitude curve.
[0020] Working principle: Using wedges with corresponding angles, connected to the probe body 3 through T-slots 8, the guide slope 11 facilitates the quick insertion of the insert strip on the wedge into the T-slot 8. Then, the baffle 4 is moved down to block the insert strip. At this time, the positions of threaded hole 1 5 and threaded hole 2 9 correspond. Screw 7 is screwed into threaded hole 1 5 and threaded hole 2 9 to fix the position of the baffle 4, thereby achieving the wedge limit. At the same time, another screw 7 can be screwed into threaded hole 3 10 to further press the insert strip on the wedge to prevent it from shaking. When it is necessary to replace the wedge with a different angle, screw 7 is unscrewed and the baffle 4 is moved up to remove the wedge. When it is not necessary to insert the wedge, the baffle 4 is moved up so that the position of threaded hole 3 10 corresponds to threaded hole 2 9, and screw 7 is screwed in. Finally, the quick installation and removal of the wedge is achieved, while ensuring the stable limit of the wedge and preventing displacement from affecting the detection.
