[0032] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0033] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0034] It is to be appreciated that the various aspects described herein are capable of implementation by various types of structures and / or functionality. For example, aspects described herein can be implemented by one or more apparatuses that include a processor and / or other structure. Similarly, aspects described herein can be implemented by one or more devices that include a processor and / or other structure.

[0035] As Figures 1 to 5 The penetration detection system of the sealing ring for aviation, the sealing ring is provided with a cut, including a hanging assembly, a box body 2 provided with an open structure at one end, a cleaning device 3, a drying device 4 and a detection device 5, the box body 2 is placed with soaking liquid, the soaking liquid, for example, silver light penetrant, if the sealing ring or the sealing ring has a crack, the silver light penetrant penetrates into the crack and is displayed as yellow-green in the imaging image of the detection device 5, wherein,

[0036] The hanging assembly can classify and hang different models of sealing rings, and when the inner ring surface of the sealing ring is soaked in the box body 2, the mutual interpenetration between the sealing rings is avoided;

[0037] The cleaning device 3 flushes the impurities on the surface of the sealing ring after soaking;

[0038] The drying device 4 performs drying treatment on the sealing ring after flushing;

[0039] The detection device 5 detects the sealing ring after drying in the form of an image.

[0040] Because the arc-shaped groove part of part of the sealing ring product is narrow when the sealing ring product is subjected to penetration detection, the traditional black light detection light source is difficult to reach the bottom of the arc-shaped groove, or the light is difficult to reflect to the naked eye of the detection personnel after entering the bottom, and the detection efficiency is low. The system soaks the sealing ring with silver light penetrant, if the inner ring surface of the sealing ring has a crack, the silver light penetrant will penetrate into the crack, and the unqualified sealing ring can be quickly identified under the detection device 5. The cleaning device 3 and the drying device 4 are integrated devices for cleaning and drying of aviation in the prior art.

[0041] As the specific implementation provided in the case, see Figure 2As shown, the hanging assembly comprises a support frame 11, a carrier rod 12 and vertical rods 13, wherein the bottom surface of the side rods of the support frame 11 is spaced apart from the vertical rods 13, and the spacing between any two adjacent vertical rods 13 is not the same, so as to adapt to the hanging of sealing rings of different models. The inner side surface of the vertical rod 13 is spaced apart in the vertical direction and is provided with hooks 14 arranged in an arc structure, the hooks 14 are used to place the carrier rod 12, and the outer side surface of the vertical rod 13 is provided with a signboard, which is marked with the spacing between adjacent vertical rods 13 and the model of the hanging sealing ring. The carrier rod 12 is axially spaced apart and provided with ring ears 15, which can limit the movement of the carrier rod 12. Generally, the spacing is N times the thickness of the sealing ring. Since sealing rings of the same model are classified, the situation that the sealing rings are inserted into each other does not occur. It should be pointed out that: when cleaning and drying, the carrier rod 12 is taken off from the support frame 11 for overall cleaning and drying.

[0042] Further, the opening formed by the hook 14 and the vertical rod 13 faces the support frame 11, and the arc angle between the hook 14 and the vertical rod 13 is 50°-60°, so as to avoid the shaking of the carrier rod 12 during soaking. The shape of the support frame 11 is quadrilateral, such as a rectangular frame.

[0043] Preferably, in order to quickly identify the position of the hanging of a sealing ring of a certain model, the spacing between adjacent vertical rods 13 increases or decreases in turn.

[0044] As the specific embodiment provided in the present case, see Figure 3 As shown, a pair of ring ears 15 are arranged between the adjacent vertical rods 13 and on the carrier rod 12, and the side surfaces of the pair of ring ears 15 respectively corresponding to the two ring ears 15 are in contact, that is, the ring ears 15 can be in contact with one side surface of the corresponding hook 14 in the initial state, so as to limit the movement of the carrier rod 12 and slightly limit the sealing ring on the carrier rod 12, so as to avoid the mutual insertion of the sealing rings during soaking.

[0045] Further, if the size of the sealing ring to be detected is less than or equal to 30 mm, one carrier rod 12 is used for hanging. If the size of the sealing ring to be detected is greater than 30 mm and less than 200 mm, two carrier rods 12 are used for hanging, wherein the two carrier rods 12 correspond to hooks 14 of different heights respectively, so as to support and hang the sealing ring. For example, two carrier rods 12 are used to support and hang the sealing ring exceeding 30 mm through two adjacent hooks 14 in the vertical direction. Preferably, the carrier rod 12 used is a polyester paint sprayed aluminum pipe / copper pipe to limit the penetration of the rod.

[0046] The sealing ring with a size less than or equal to 30 mm is arranged at different positions of the carrier rod 12 corresponding to different inner diameters of the sealing ring, that is, the suspension between the two vertical rods and the carrier rod 12 corresponding to different inner diameters of the sealing ring, effectively arranging the sealing rings in front of and behind each other, and the sealing rings will not be inserted into other products due to the limited swing range in the sliding process.

[0047] For the sealing ring with a diameter greater than 30 mm, two carrier rods 12 are used to limit the swing range of two points on the inner wall of the ring-shaped part, avoiding the product insertion in the infiltration and cleaning process, and the carrier rod is fixed on the product infiltration tool to simultaneously detect multiple products by using the carrier hook and the limiting device.

[0048] Further, the top surface of the support frame 11 is provided with a lifting ring 16, and the support frame 11 can be lifted by the lifting ring 16 and placed in the box 2 for soaking.

[0049] As the specific embodiment provided in the present case, referring to Figure 4 As shown in the figure, the detection device 5 includes a base 61, a support rod 62, a horizontal rod 63 and a camera device 64. The camera device 64 is preferably a camera device 64 with five lens tubes in the prior art, which can magnify the camera of the sealing ring. Among them,

[0050] The base 61 is provided with a display device with a controller, and the display device is electrically connected with the camera device 64;

[0051] The support rod 62 is installed at the top edge position of the base 61, and the horizontal rod 63 is rotatably installed at one end of the camera device 64 and rotatably connected with the support rod 62 at the other end. For example, the support rod 62 is provided with an adjusting knob at the corresponding position, and the relative angle between the horizontal rod 63 and the support rod 62 can be adjusted by rotating the adjusting knob. Alternatively, the horizontal rod 63 is fixedly connected with the support rod 62 at one end, and the camera device 64 is rotatably installed at the other end by providing an adjusting knob. The camera device 64 can also be an "optical endoscope WA2T430A Olympus" device. The camera device 64 can magnify the sealing ring placed on the base 61 and transmit it to the display device for display. The operator can quickly identify whether there is yellow-green on the inner ring surface of the sealing ring by watching the display device. If there is, the sealing ring is unqualified, and if not, the sealing ring is qualified.

[0052] Preferably, the camera device 64 can emit a rigid UV light source, which can endoscope the blind area of the sealing ring fluorescence penetration, avoiding the situation that the naked eye cannot directly detect.

[0053] Further, the camera device 64 can also be a handheld device, and one operator can hold the camera device 64 to acquire the image of the seal ring on the carrier rod 12, and another operator can watch the display device.

[0054] The distance between the short light source of the camera device 64 and the detection surface of the seal ring can be adjusted, and the display of the arc-shaped groove defects of the inner ring surface of the seal ring is observed by the camera device 64, so that the technical problem that some seal rings cannot be detected or are difficult to be detected due to the too narrow arc-shaped groove part is solved.

[0055] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present disclosure, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
