Description

Technical Field

[0001] This utility model relates to the field of nondestructive testing technology, and more specifically, to a detection device based on fluorescence penetration. Background Technology

[0002] With the continuous development of aerospace technology, more and more non-ferrous metals and non-ferromagnetic materials are being widely used in the aerospace field. The structure of aerospace parts is becoming increasingly complex, and these parts need to undergo flaw detection testing before being put into use. Among the existing flaw detection technologies, commonly used flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection, and gamma-ray flaw detection. Fluorescent penetrant testing is used to inspect the surface quality of aerospace parts. Fluorescent penetrant testing is a non-destructive testing method for detecting open defects on the surface of non-porous materials and parts. After the aerospace parts are permeated in a fluorescent penetrant, the penetrant penetrates into the open defects on the surface under the action of capillary action. Then, the excess penetrant on the surface is removed, and after drying, a uniform and thin layer of developer is applied to the surface of the aerospace parts. The penetrant that has penetrated into the defects is re-adsorbed to the surface of the parts by the capillary action of the developer. The surface quality of the aerospace parts is then determined under a black light to determine whether it is up to standard.

[0003] For example, Chinese patent CN210322831U discloses a robotic fluorescence penetrant detection line, which includes a detection line body and a robot that moves along the detection line body. The detection line body includes at least two fluorescence penetrant detection tank structures. The robot includes a moving track and at least two robotic arms, which are sequentially hinged to be adapted to move around the hinge connection axis. The end of the last segment of the robotic arm away from the hinge connection axis is provided with a gripping device.

[0004] When in use, the gripping module can adjust the gripping angle to be suitable for gripping the workpiece entering and exiting the fluorescent penetrant detection tank. However, after the workpiece has completed fluorescent penetrant testing, it still needs to be transferred to another location for fluorescent detection. This makes it difficult to achieve continuity between fluorescent penetrant testing and fluorescent detection, resulting in low detection efficiency and inconvenience. Utility Model Content

[0018] This invention transfers the workpiece to the detector after immersion, allowing each detection frame to cover the outside of the workpiece. This enables each fluorescent detection lamp to perform a comprehensive inspection of the workpiece without repeated angle adjustments. The comprehensive, enveloping inspection function also avoids blind spots during inspection, ensuring detection accuracy. Attached Figure Description

Detailed Implementation

[0026] 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.

[0027] This application discloses a detection device based on fluorescence penetration. For example... Figure 1-4 As shown, the testing device includes a support frame 1, which contains a transfer station, an immersion station, and a testing station. The transfer station has at least one workpiece placement basket 19, the immersion station has at least one immersion tank 2, and the testing station has at least one detector 3. The workpiece placement basket 19, the immersion tank 2, and the detector 3 are arranged in a straight line. The support frame 1 contains a guide rail 14 along the arrangement direction of the workpiece placement basket 19, the immersion tank 2, and the detector 3. A vertically arranged sliding plate 6 is slidably connected to the guide rail 14. A connecting seat 7 is slidably connected to one side of the sliding plate 6 in a vertical direction. The connecting seat 7 is equipped with a gripping mechanism adapted to the workpiece placement basket 19.

[0028] When using the above structure, the operator installs the detection device at the designated location. During fluorescence penetrant testing of the workpiece, the workpiece is placed in the feeding basket 19. The sliding plate 6 drives the connecting seat 7 and the gripping mechanism to adjust their positions on the guide rail 14. Then, the connecting seat 7 drives the gripping mechanism to move in the height direction of the sliding plate 6, allowing the gripping mechanism to extend to the feeding basket 19 and pick it up. The connecting seat 7 and the gripping mechanism are then moved upwards on the sliding plate 6 again, thereby lifting the feeding basket 19 so that the sliding plate 6 can move on the guide rail 14. The material basket 19, along with the workpiece, is transferred to the immersion tank 2 for immersion, facilitating material handling and improving the convenience of testing. After immersion, the material basket 19 is lifted and left to stand, allowing excess penetrant to be removed from the workpiece surface, leaving only penetrant within the defects. A developer is then sprayed onto the workpiece, causing the penetrant within the defects to reabsorb onto the surface. The material basket 19 and the workpiece are then transferred to the detector 3 using the same process to complete the fluorescence detection of the workpiece. The entire fluorescence penetrant and fluorescence detection process is convenient, fast, and highly continuous, greatly improving the efficiency of workpiece detection.

[0029] In some embodiments of this utility model, such as Figure 1 and Figure 4 As shown, the detector 3 includes an outer casing and multiple detection frames 4 installed on the inner wall of the outer casing. The multiple detection frames 4 are stacked along the height direction of the outer casing, and each detection frame 4 has several fluorescent detection lamps 5 installed on the side facing the center of the outer casing.

[0030] In this embodiment, when performing fluorescence detection on the workpiece, the workpiece is placed inside the outer box, and each detection frame 4 can cover the outside of the workpiece. Each fluorescence detection lamp 5 can perform a comprehensive detection function on the workpiece. Compared with other methods such as using a robotic arm, which involves the cumbersome method of adjusting the angle during fluorescence detection, this utility model eliminates the need for repeated angle adjustments, effectively improving detection efficiency and reducing operational difficulty. At the same time, the comprehensive detection function can also avoid blind spots during detection, effectively ensuring detection accuracy.

[0031] In some embodiments of this utility model, the number of detection frames 4 includes, but is not limited to, two, three, or four.

[0032] Furthermore, the number of fluorescent detection lamps 5 installed on each detection frame 4 includes, but is not limited to, two, three, four, five, or six.

[0033] In some embodiments of this utility model, such as Figure 2 and Figure 5As shown, the gripping and releasing mechanism includes a limiting plate 9 on each side of the connecting seat 7. The two limiting plates 9 are spaced apart along the length of the guide rail 14. Each limiting plate 9 has multiple vertically arranged pull rods 10 spaced apart along the direction perpendicular to the slide plate 6. Each pull rod 10 has a hook 11 at its bottom end. The connecting seat 7 is equipped with a distance adjuster for adjusting the distance between the two limiting plates 9.

[0034] In this embodiment, when it is necessary to grab or release the material basket 19, after the pull rod 10 is lowered into the material basket 19, the distance between the two limiting plates 9 can be adjusted by the distance adjuster so that the two limiting plates 9 move closer or further away from each other, so that each hook 11 is hooked or unhooked with the horizontally arranged rod on the material basket 19, thereby completing the grabbing or release of the material basket 19. The structure is simple, the grabbing stability of the material basket 19 is high, and the material basket 19 is guaranteed to run smoothly along the length direction of the guide rail 14.

[0035] In some embodiments of this utility model, such as Figure 5 As shown, the distance adjuster includes at least two parallel and spaced guide rods 12 fixed on the connecting seat 7, and the guide rods 12 are arranged parallel to the guide rail 14. The two ends of the guide rods 12 pass through two limiting plates 9 respectively, and the limiting plates 9 are slidably connected to the guide rods 12.

[0036] In this embodiment, the distance between the two limiting plates 9 can be adjusted simply and quickly by sliding the limiting plate 9 with the guide rod 12 installed on the connecting seat 7. Furthermore, by having multiple guide rods 12 spaced apart and passing through different parts of the limiting plate 9, it can be ensured that the limiting plate 9 does not deviate when it is in a stationary or sliding state, which further ensures the stability of the hook 11 hooking the material basket 19.

[0037] In some embodiments of this utility model, the number of guide rods 12 includes, but is not limited to, two, three or four, preferably two, which ensures the stability of the sliding of the limiting plate 9 and avoids excessive occupation of the space of the connecting seat 7.

[0038] Furthermore, the cross-sectional shape of the guide rod 12 includes, but is not limited to, a circle or a rectangle, with a circle being preferred.

[0039] In some embodiments of this utility model, such as Figure 5 As shown, the distance adjuster also includes two electric push rods 8 mounted on the connecting seat 7. The electric push rods 8 are arranged parallel to the guide rail 14. The two ends of one electric push rod 8 are connected to the connecting seat 7 and one of the limiting plates 9, respectively, and the two ends of the other electric push rod 8 are connected to the connecting seat 7 and the other limiting plate 9, respectively.

[0040] In this embodiment, the electric push rod 8 can automatically adjust the position of the two limiting plates 9 on the guide rod 12, which is convenient and accurate.

[0041] In other embodiments of this utility model, the number of electric push rods 8 can also be set to one, with both ends of the electric push rod 8 connected to two limiting plates 9 respectively, or with both ends of the electric push rod 8 connected to one of the limiting plates 9 and the connecting seat 7 respectively, as long as the distance between the two limiting plates 9 can be adjusted, which is not limited here.

[0042] Furthermore, in addition to using the electric push rod 8, other linear transmission mechanisms such as linear motors and electric cylinders can also be used, which are not limited here.

[0043] In some embodiments of this utility model, the two ends of the electric push rod 8 can be fixed to the connecting seat 7 and the limiting plate 9 by bolts.

[0044] In some embodiments of this utility model, such as Figure 5 As shown, the hook 11 is located on one side of the two sets of pull rods 10 on the two limiting plates 9, facing away from each other.

[0045] In this embodiment, two sets of hooks 11 are set on the opposite side of the two sets of pull rods 10. When the two limiting plates 9 move away from each other, they can be hooked from the inside of the discharge basket 19, which can provide higher stability. The pull rods 10 are located inside the discharge basket 19, avoiding protrusion from the outer wall of the discharge basket 19 and reducing the possibility of collision with the soaking tank 2 and the detector 3.

[0046] In other embodiments of this utility model, the two sets of hooks 11 may also be set on the opposite side of the two sets of pull rods 10, as long as they can be hooked onto the material basket 19, and this is not limited here.

[0047] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, a vertically arranged hydraulic rod 13 is provided between the slide plate 6 and the connecting seat 7, and the two ends of the hydraulic rod 13 are connected to the slide plate 6 and the connecting seat 7 respectively.

[0048] In one embodiment of this utility model, the cylinder end of the hydraulic rod 13 is fixed to the top of the slide plate 6, and the output end of the hydraulic rod 13 extends downward and is fixed on the connecting seat 7; when the hydraulic rod 13 extends, it drives the connecting seat 7 to move downward, and when the hydraulic rod 13 retracts, it drives the connecting seat 7 to move upward.

[0049] Furthermore, to improve the stability of the hydraulic cylinder driving the connecting seat 7 on the slide plate 6, the connecting seat 7 and the slide plate 6 can be slidably engaged by the slider 15 and the slide rail. The sliding connection between the slider 15 and the slide rail assists the hydraulic cylinder in driving the connecting seat 7 to move, thereby reducing the load on the hydraulic cylinder.

[0050] Furthermore, in addition to using hydraulic rod 13, other linear transmission mechanisms such as cylinders, ball screws, and timing belts can also be used, which are not limited here.

[0051] In one embodiment of this utility model, the two ends of the hydraulic rod 13 can be fixed to the slide plate 6 and the connecting seat 7 by bolts.

[0052] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, racks 16 are provided inside the support frame 1, parallel to and spaced apart from the guide rail 14. A drive motor 17 is fixed on the slide plate 6, and a gear 18 that meshes with the rack 16 is provided at the output end of the drive motor 17.

[0053] In this embodiment, the drive motor 17 drives the gear 18 to rotate, which causes the gear 18 to move relative to the rack 16, thereby driving the slide plate 6 to move in a straight line along the guide rail 14. This allows for automatic adjustment of the position of the slide plate 6 on the guide rail 14, which is convenient and accurate.

[0054] In some embodiments of this utility model, the drive motor 17 can be connected to the slide plate 6 by bolts.

[0055] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, there are two or more guide rails 14 spaced apart, and each guide rail 14 has a slider 15 slidably connected to it. The slide plate 6 is fixedly connected to each slider 15.

[0056] In this embodiment, multiple guide rails 14 are provided, and the slide plate 6 is connected to the multiple guide rails via multiple sliders 15. This can improve the stability of the slide plate 6 installed on the support frame 1, thereby improving the stability of the slide plate 6 moving in the straight direction along the guide rails 14.

[0057] In some embodiments of this utility model, the slider 15 can be connected to the slide plate 6 by bolts.

[0058] In some embodiments of this utility model, the number of guide rails 14 includes, but is not limited to, two, three or four, with two being preferred.

[0059] In some embodiments of this utility model, the guide rail 14 can be fixed to the support frame 1 by bolts.

[0060] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the transfer station is equipped with a trolley 20 for carrying and transferring the material basket 19.

[0061] In this embodiment, the trolley 20 can be used to transfer the material basket 19 along with the workpiece to be measured to the transfer station or to transfer the workpiece that has been measured from the transfer station, which can reduce labor intensity and improve the detection efficiency of the workpiece.

[0062] In some embodiments of this utility model, the number of material baskets 19 that can be accommodated at the transfer station includes, but is not limited to, one, two, or three; the number of soaking tanks 2 that can be accommodated at the soaking station includes, but is not limited to, one, two, or three; and the number of detectors 3 that can be accommodated at the detection station includes, but is not limited to, one, two, or three.
