Description

Technical Field

[0001] This utility model belongs to the technical field of ultrasonic plate flaw detection equipment, and particularly relates to an adaptive structure for ultrasonic flaw detection based on a combination of double cylinder springs and hinges. Background Technology

[0002] During the production of sheet materials, various factors can lead to defects such as cracks, pores, and inclusions within the material. If these defects are not detected promptly, they can severely impact the performance and safety of the sheet material in subsequent use. Ultrasonic testing technology, with its ability to penetrate the interior of the sheet material and its sensitivity to defects, has gradually become an important method in the field of sheet material flaw detection.

[0003] However, existing ultrasonic flaw detection structures still face some challenges in practical applications. For example, during the flaw detection process, it is difficult to couple the adaptive testing device with the continuously undulating surface of the plate, and it is difficult to ensure the uniformity of the downward pressure during the adaptive pressing process. These problems limit the efficiency of plate flaw detection and also greatly affect the flaw detection results.

[0004] See Figure 1 and Figure 2 In existing technologies, when using an adaptive structure for pressure testing with a single cylinder, coupling can still be achieved on the warped plate surface. However, if... Figure 2 When the continuously warped plate surface is shown, a non-coupled state will occur where one end of the adaptive flaw detector is in close contact with the plate surface and the other end is offset from the plate surface. Even with the coupling of the coupling fluid, the adaptive flaw detector will still have poor detection performance. Utility Model Content

[0005] The purpose of this invention is to solve the problems of poor adaptability, uneven pressure, and low inspection efficiency of existing adaptive structures for flaw detection. It provides an adaptive structure for ultrasonic flaw detection based on a combination of a double-cylinder spring and a hinge, which can provide uniform downward pressure for the adaptive structure, ensure stable coupling between the adaptive structure and the plate surface, and improve work efficiency and inspection effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adaptive structure for ultrasonic flaw detection based on a combination of dual-cylinder springs and hinges includes a fixed mounting base. A set of multi-axis cylinders is fixed on both sides of the fixed mounting base. The telescopic ends of the multi-axis cylinders are arranged downwards, and their cylinder joints are respectively connected to the left lower pressure frame and the right lower pressure frame on the corresponding side. Tension springs are connected between the fixed mounting base and the left lower pressure frame, and between the fixed mounting base and the right lower pressure frame. A four-sided frame is provided between the left lower pressure frame and the right lower pressure frame, and the holes of the left and right lower pressure frames are hinged to the shaft of the four-sided frame. The holes of the four-sided frame are then hinged to the shaft of the adaptive structure for flaw detection.

[0008] Furthermore, the fixed mounting base includes a fixed plate, a left side plate, a right side plate, and a positioning shaft. The left side plate and the right side plate are vertically connected to the bottom sides of the fixed plate, and a set of positioning shafts connects the left side plate and the right side plate.

[0009] Furthermore, the left and right side plates are arranged parallel to each other, and the positioning shafts are perpendicular to the left and right side plates. There are two pairs of positioning shafts, one pair of which is fixed in the middle of the left and right side plates, and the other pair is fixed in the lower end of the left and right side plates, in order to improve the overall structural strength and stability of the fixed mounting base.

[0010] Furthermore, the lower left pressure frame includes a left cylinder connecting plate, a left front upright plate, and a left rear upright plate. The multi-axis cylinder on the left side is connected to the left cylinder connecting plate. The left front upright plate and the left rear upright plate are respectively fixed to the front end and the rear end of the left cylinder connecting plate. A horizontal left tension spring pin is fixed to the middle of the inner side of the left cylinder connecting plate.

[0011] Furthermore, the lower right pressure frame includes a right cylinder connecting plate, a right front upright plate, and a right rear upright plate. The multi-axis cylinder on the right side is connected to the right cylinder connecting plate. The right front upright plate and the right rear upright plate are respectively fixed to the front end and the rear end of the right cylinder connecting plate. A horizontal right tension spring pin is fixed to the inner middle of the right cylinder connecting plate.

[0012] Furthermore, the tension spring includes a left tension spring and a right tension spring. The upper and lower ends of the left tension spring are respectively connected to the left tension spring fixing pin and the left tension spring hanging pin, and the upper and lower ends of the right tension spring are respectively connected to the right tension spring fixing pin and the right tension spring hanging pin.

[0013] Furthermore, the four-sided frame includes a front frame, a rear frame, a left frame, and a right frame connected in sequence. The two sides of the front frame are connected to the left front upright plate and the right front upright plate, respectively. The two sides of the rear frame are connected to the left rear upright plate and the right rear upright plate, respectively. The middle part of the left frame is connected to the left side of the flaw detection adaptive plate, and the middle part of the right frame is connected to the right side of the flaw detection adaptive plate.

[0015] Furthermore, the telescopic shaft, left tension spring, right tension spring, left front upright plate, left rear upright plate, right front upright plate, and right rear upright plate of the multi-axis cylinder are all arranged parallel to the central axis of the fixed mounting base.

[0016] Compared with the prior art, the advantages of the technical solution of this utility model are as follows:

[0017] (1) By setting up a multi-axis cylinder with both sides facing downward, this utility model can ensure that the inspection tool generates uniform downward pressure on both sides, which is highly practical and the structure is more stable and reliable.

[0018] (2) This utility model achieves the function of adaptive floating coupling for flaw detection by hinged with the four-sided frame, the lower left pressure frame, the lower right pressure frame and the self-adaptive shaft hole for flaw detection;

[0019] (3) The structure of this utility model can not only meet the requirements of ultrasonic flaw detection for adaptive coupling to the surface of the steel plate, but also adapt to the continuous unevenness of the object surface during the cylinder pressing process.

[0030] To make this utility model clearer, the following description, in conjunction with the accompanying drawings, further illustrates an adaptive structure for ultrasonic flaw detection based on a combination of a double-cylinder spring and a hinge. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0031] See Figure 3 and Figure 8 An adaptive structure for ultrasonic flaw detection based on a dual-cylinder combined spring and hinge, comprising a fixed mounting base 1, characterized in that:

[0032] See Figure 3 and Figure 4 The fixed mounting base 1 includes a fixed plate 11, a left side plate 12, a right side plate 13, and a positioning shaft 14. The left side plate 12 and the right side plate 13 are vertically connected to the bottom sides of the fixed plate 11, and a set of positioning shafts 14 connects the left side plate 12 and the right side plate 13. A left tension spring fixing pin 15 is provided on the upper inner side of the left side plate 12, and a right tension spring fixing pin 16 is provided on the upper inner side of the right side plate 13. The left tension spring fixing pin 15 and the right tension spring fixing pin 16 are on the same horizontal line.

[0033] The left side plate 12 and the right side plate 13 are arranged parallel to each other. The positioning shaft 14 is perpendicular to the left and right side plates. There are two pairs of positioning shafts 14. One pair is fixed in the middle of the left and right side plates, and the other pair is fixed in the lower end of the left and right side plates to improve the overall structural strength and stability of the fixed mounting base.

[0034] See Figure 3 , Figure 5 and Figure 8 A set of multi-axis cylinders 2 are fixed to the outside of the left side plate 12 and the right side plate 13 of the fixed mounting base 1. The telescopic end of the multi-axis cylinder 2 is set downward, and its cylinder joint is connected to the left lower pressure frame 3 and the right lower pressure frame 4 on the corresponding side. The left lower pressure frame 3 includes a left cylinder connecting plate 31, a left front upright plate 32 and a left rear upright plate 33. The multi-axis cylinder 2 on the left side is connected to the left cylinder connecting plate 31. The left front upright plate 32 and the left rear upright plate 33 are fixed to the front end and the rear end of the left cylinder connecting plate 31, respectively. A horizontally extending left tension spring pin 34 is fixed to the middle of the inner side of the left cylinder connecting plate 31.

[0035] See Figure 3 , Figure 6 and Figure 8 The lower right pressure frame 4 includes a right cylinder connecting plate 41, a right front upright plate 42 and a right rear upright plate 43. The multi-axis cylinder 2 on the right side is connected to the right cylinder connecting plate 41. The right front upright plate 42 and the right rear upright plate 43 are respectively fixed to the front end and the rear end of the right cylinder connecting plate 41. A horizontally extending right tension spring pin 44 is fixed in the middle of the inner side of the right cylinder connecting plate 41.

[0036] Tension springs 5 ​​are connected between the fixed mounting base 1 and the lower left pressure bracket 3, and between the fixed mounting base 1 and the lower right pressure bracket 4. The tension springs 5 ​​include a left tension spring 51 and a right tension spring 52. The upper and lower ends of the left tension spring 51 are connected to the left tension spring fixing pin 15 and the left tension spring hanging pin 34, respectively. The upper and lower ends of the right tension spring 52 are connected to the right tension spring fixing pin 16 and the right tension spring hanging pin 44, respectively.

[0037] See Figure 3 , Figure 7 and Figure 8 A four-sided frame 6 is provided between the lower left pressure frame 3 and the lower right pressure frame 4. The four-sided frame 6 includes a front frame 61, a rear frame 62, a left frame 63 and a right frame 64 connected in sequence. The two sides of the front frame 61 are connected to the left front upright plate 32 and the right front upright plate 42 respectively. The two sides of the rear frame 62 are connected to the left rear upright plate 33 and the right rear upright plate 43 respectively. The middle part of the left frame 63 is connected to the left side of the flaw detection adaptive 7, and the middle part of the right frame 64 is connected to the right side of the flaw detection adaptive 7.

[0038] See Figure 5 , Figure 6 and Figure 7 The outer sides of the front frame 61 and the rear frame 62 are respectively provided with a pair of convex shafts 8. The inner sides of the left frame 63 and the right frame 64 are respectively provided with shaft holes 9. The lower ends of the left front upright plate 32, the left rear upright plate 33, the right front upright plate 42 and the right rear upright plate 43 are all provided with shaft holes 10. The shaft holes 10 are connected to the convex shafts 8 on the corresponding sides. The shaft holes 9 are connected to the shafts on both sides of the flaw detection adaptive 7, thereby realizing the effect of adaptive floating coupling for flaw detection.

[0039] In this embodiment, the lower left pressure frame 3 transmits the downward pressure of the multi-axis cylinder 2 on the left side to the left side of the four-sided frame 6 through the hinge of the shaft and the hole, ultimately causing the left side of the flaw detection adaptive 7 to be subjected to downward pressure; the lower right pressure frame 4 transmits the downward pressure of the multi-axis cylinder 2 on the right side to the right side of the four-sided frame 6 through the hinge of the shaft and the hole, ultimately causing the right side of the flaw detection adaptive 7 to be subjected to downward pressure.

[0040] See Figure 1 and Figure 9 When encountering a warped plate surface A, only one set of cylinders is used to provide downward pressure from the middle, such as... Figure 1 As shown, the coupling effect is the same as that of the embodiment of this utility model, which uses two sets of cylinders to provide downward pressure from both sides, as... Figure 9 As shown.

[0041] However, when encountering a continuously warped plate surface B, only one set of cylinders was used to provide downward pressure from the middle, such as... Figure 2 As shown, this will result in a non-coupled state where one end of the adaptive flaw detector is in close contact with the surface of the plate, while the other end is offset from the surface of the plate. Even with the coupling of the coupling fluid, this will still lead to poor adaptive flaw detector performance.

[0042] This utility model embodiment discloses an adaptive structure for ultrasonic flaw detection based on a dual-cylinder combined spring and hinge, employing two sets of multi-axis cylinders to provide downward pressure from both the left and right sides, such as... Figure 10 As shown, when encountering a continuously warped plate surface, because both sides of the self-adaptive flaw detector have the same downward pressure, the self-adaptive flaw detector achieves flexible floating by hinged with the four-sided frame, the left and right downward pressure frames, and the shaft hole of the self-adaptive flaw detector. Therefore, the self-adaptive flaw detector will maintain horizontal downward pressure. Furthermore, through the coupling of the coupling fluid, the self-adaptive flaw detector can ensure good detection results.

[0043] In summary, in scenarios involving continuously warped surfaces, the dual-cylinder operation from both sides improves the adaptive coupling effect along the length direction compared to a single-cylinder operation. This ensures sufficient pressure is applied while meeting the coupling requirements for flaw detection. This structure is suitable for ultrasonic flaw detection applications requiring adaptive coupling to the surface of the steel plate being inspected, while also requiring the cylinder pressing process to adapt to the continuously uneven surface of the object.

[0044] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
