Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing technology, specifically a phased array raw material testing device. Background Technology

[0002] As a fundamental material in the industrial field, the surface quality of steel plates directly impacts the safety and service life of equipment. However, traditional ultrasonic testing techniques, due to insufficient flexibility and low imaging resolution, struggle to meet the demands for precise detection of complex defects. Phased array ultrasonic probe technology, through electronic control to achieve dynamic focusing and deflection of the sound beam, significantly improves detection efficiency and defect identification capabilities, thus becoming a research hotspot in the field of steel plate surface defect detection.

[0003] In practical applications, XYZ track modules are currently commonly used to move the probe along its path. However, this approach is costly, and replacing it with a robotic arm would be even more expensive. Reducing the number of tracks would make it unsuitable for curved surfaces or irregularly shaped steel plates. Furthermore, the surface roughness of flat steel plates can lead to unstable coupling, resulting in false reflection signals and affecting the accuracy of the detection results.

[0004] Therefore, this application proposes a phased array raw material detection device that is lower in cost and can adapt to the detection of various steel plates. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a phased array raw material testing device, which solves the problem that current phased array testing devices used for steel plates are difficult to combine low cost and strong adaptability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a phased array raw material testing device, comprising an XY track module and a support, wherein the support includes a clamp for clamping a phased array ultrasonic probe and a connecting rod rotatably connected between the clamp and the XY module, and the rotation axis of the connecting rod is parallel to the XY plane of the XY track module and parallel to the rotation axis of the clamp.

[0007] Preferably, the clamp is connected to the connecting rod via a vertical rod, and the vertical rod is rotatably connected between the connecting rod and the clamp. The rotation axis between the vertical rod and the connecting rod is parallel to the XY plane of the XY track module and perpendicular to the rotation axis of the clamp.

[0008] Preferably, the clamp is U-shaped and includes a main rod for connecting the upright and a support rod for connecting the two ends of the main rod. The support rod is provided with a knob screw to fix the probe.

[0009] Preferably, the main rod is also provided with a waist-shaped hole, and at least one of the support rods is threaded onto the waist-shaped hole.

[0010] Preferably, the XY track module includes an X track, a Y track, and a connecting frame. The X track is slidably connected to the Y track via the connecting frame, and the support is slidably connected to the X track via the connecting frame.

[0012] Preferably, it also includes a control module, wherein the input terminal of the XY track module is electrically connected to the output terminal of the control module.

[0013] Preferably, it also includes a wireless communication module, which is electrically connected to the control module.

[0014] Compared with the prior art, this utility model provides a phased array raw material detection device, which has the following beneficial effects: This phased array raw material testing device addresses the limitations of current phased array testing devices when applied to different steel plate surfaces in a low-cost manner.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please see Figure 1-2 The present invention provides the following technical solution: a phased array raw material testing device, including an XY track 12 module 1 and a support 2. The support 2 includes a clamp 21 for clamping a phased array ultrasonic probe A and a connecting rod 22 rotatably connected between the clamp 21 and the XY module. The rotation axis of the connecting rod 22 is parallel to the XY plane of the XY track 12 module 1 and parallel to the rotation axis of the clamp 21.

[0019] As an optional implementation of this utility model, the XY track 12 module 1 and the clamp 21 for mounting the probe A are rotatably connected by the connecting rod 22, so that the probe A has rotational and lifting freedom when passing over the steel plate surface. That is to say, when dealing with the detection of flat steel plates, curved surfaces or irregular steel plates, the probe A can adapt its movement according to the roughness, protrusions and depressions, so as to maintain its contact with the steel plate surface. Therefore, the adaptability is improved and the accuracy is improved. Compared with the existing robotic arm or XYZ module, this implementation method is also significantly lower in cost.

[0020] In this technical solution, the XY track 12 module 1 should be considered as a component that reduces one track from the existing XYZ module. It can move the probe A in a two-dimensional plane. Therefore, the concept of this technical solution should be understood as consisting only of the XY track 12 module 1, the bracket 2, and the probe A at the hardware level, without the need for additional tracks. Of course, the XY track 12 module 1 should not be limited to a track on a horizontal plane, but should be understood as a two-dimensional planar track, which can also be a vertical plane, an inclined plane, etc. The clamp 21 can be regarded as a connector of the probe A on the connecting rod 22, or it can be a bracket. The way the two ends of the connecting rod 22 are rotatably connected to the adjacent components is limited to the axis being parallel to the plane provided by the XY track 12 module 1 itself, and these two rotation axes are parallel to each other. Therefore, the two rotational degrees of freedom provided allow the probe A to tilt and rise and fall during movement, thus supporting the function of adapting to different steel plate surfaces.

[0021] The above structure solves the limitations of current phased array detection devices when applied to different steel plate surfaces in a low-cost hardware manner. During detection, probe A can always adapt to the surface shape of the steel plate, and the detection accuracy is greatly improved.

[0022] Example 2: Please see Figure 1-2 The present invention provides the following technical solution: a phased array raw material testing device, including an XY track 12 module 1 and a support 2. The support 2 includes a clamp 21 for clamping a phased array ultrasonic probe A and a connecting rod 22 rotatably connected between the clamp 21 and the XY module. The rotation axis of the connecting rod 22 is parallel to the XY plane of the XY track 12 module 1 and parallel to the rotation axis of the clamp 21. The clamp 21 is connected to the connecting rod 22 via the upright 23, and the upright 23 is rotatably connected between the connecting rod 22 and the clamp 21. The rotation axis between the upright 23 and the connecting rod 22 is parallel to the XY plane of the XY track 12 module 1 and perpendicular to the rotation axis of the clamp 21.

[0023] As an optional implementation of this utility model, the connecting rod 22 and the clamp 21 are rotatably connected by the upright 23, so that the probe A has an additional degree of rotational freedom in a different direction. This allows it to fit more closely to the surface of the steel plate in three-dimensional space when dealing with the inspection of convex or concave curved steel plates, further improving the adaptability and inspection accuracy of this inspection device, and only adding one component in terms of cost.

[0024] Furthermore, in order to improve the connection stability and quick-release performance between the clip 21, which serves as a connector, and the probe A, the clip 21 can be designed to allow for quick installation and removal of the probe A.

[0025] For example, the clip 21 is U-shaped and includes a main rod 211 for connecting the upright 23 and a support rod 212 for connecting the two ends of the main rod 211. The support rod 212 is provided with a knob screw 213 to fix the probe A.

[0026] As an optional implementation of this utility model, the knob screw 213 can quickly clamp the probe A, facilitating quick installation and disassembly.

[0027] Furthermore, in order to improve the connection stability and compatibility between the clip 21, which serves as a connector, and probes A of different specifications, the main rod 211 is also provided with a waist-shaped hole 2111, and at least one support rod 212 is threadedly connected to the waist-shaped hole 2111.

[0028] As an optional implementation of this utility model, the waist-shaped hole 2111 makes the connection position between the screw and the main rod 211 variable, so the distance between the two main rods 211 is adjustable. Therefore, when dealing with probes A of different specifications, the design of the waist-shaped hole 2111 enables the bracket 2 to adapt to probes A of different specifications and sizes.

[0029] like Figure 2-3 As shown, the XY track 12 module 1 includes an X track 11, a Y track 12, and a connecting frame 13. The X track 11 is slidably connected to the Y track 12 via the connecting frame 13, and the bracket 2 is slidably connected to the X track 11 via the connecting frame 13. The connecting frame 13 includes: Upright plate 131, two upright plates 131 are connected together by bolts 132 and clamp the two side walls of X track 11; Roller 133 is rotatably connected to vertical plate 131; The connecting rod 22 is rotatably connected to the vertical plate 131.

[0030] As an optional implementation of this utility model, by further defining the structure of the XY track 12 module 1, when the probe A moves on the surface of the steel plate being measured, the roller 133 can roll on the track, thereby improving the smoothness of the movement of the probe A.

[0031] Furthermore, in order to automate the implementation of this testing device, the operation of the XY track 12 module 1 can be controlled by the control module 3. The input end of the XY track 12 module 1 is electrically connected to the output end of the control module 3, thereby realizing automated testing of steel plates without manual intervention, making the testing process more convenient.

[0032] Furthermore, traditional phased array ultrasonic probes A are wired. When applied to this technical solution, the cable may exert a pulling force on probe A, which poses risks of cable entanglement and damage, as well as the risk of pulling on probe A and affecting accuracy.

[0033] For example, such as Figure 4 As shown, it also includes a wireless communication module 4, which is electrically connected to the control module 3.

[0034] As one possible implementation of this utility model, such as Figure 4 As shown, the phased array ultrasonic probe A acquires data wirelessly in real time via the wireless communication module 4, thus avoiding the aforementioned risks associated with cables during probe A movement detection. Of course, the wireless communication module 4 can utilize various methods, including but not limited to Bluetooth and Wi-Fi, which are common existing technologies and will not be elaborated upon in this technical solution.

[0035] This embodiment mainly describes the three rotational degrees of freedom to support the movement of probe A against the steel plate surface during the movement of module 12 on the XY track. For the separation of the probe A edge from the steel plate in the case of curved surfaces, this can be achieved through software-level technologies, such as Chinese invention patent CN114487115B ("A High-Resolution Non-Destructive Testing Method for Defects Based on the Combination of Canny Operator and Ultrasonic Plane Wave Imaging") and Chinese invention patent CN113888471B ("An Efficient and High-Resolution Non-Destructive Testing Method for Defects Based on Convolutional Neural Networks"), etc. However, this is not part of the hardware concept of this technical solution, and therefore will not be elaborated upon further.

[0036] The working principle and usage process of this utility model are as follows: The operation of the XY track 12 module 1 is controlled by the control module 3, which drives the probe A to move on the steel plate being measured. When it encounters a protrusion or depression on the steel plate, the three rotational degrees of freedom between the connecting rod 22, the upright rod 23 and the clamp 21 allow it to rise and fall and tilt with the surface of the steel plate, thereby maintaining the fit between the probe and the steel plate.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
