Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0026] In one embodiment, such as Figures 1-5 As shown, a housing inspection device includes a base 11. A placement block 19 for placing a flange housing 20 is installed on the upper end of the base 11. An upper pressure block 18 is arranged directly above the placement block 19. An inspection element 182 is embedded in the middle of the lower end of the upper pressure block 18. Several support rods 12 are fixed on the upper end of the base 11. A top seat 13 is fixed on the upper end of the support rods 12. An adjustment structure for adjusting the height of the upper pressure block 18 is installed on the top seat 13.
[0027] The flange housing 20 includes a bottom shell 201 and interfaces 202 symmetrically fixed on both sides of the upper end of the bottom shell 201. A sealing ring 203 is installed at the lower end of the bottom shell 201.
[0028] In this embodiment, the flange housing 20 is placed on the placement block 19. The detection element 182 can take pictures of the surface of the flange housing 20 and upload them to the computer. By checking whether there are defects such as scratches, cracks, and deformations on the surface, the adjustment structure can adjust the height of the upper pressure block 18, thereby adjusting the height of the detection element 182. This helps to ensure that the image taken of the flange housing 20 remains clear.
[0029] In an optional embodiment, the adjustment structure includes a cylinder 14 mounted on the upper end of the top seat 13, the telescopic end of the cylinder 14 extending to the lower end of the top seat 13 and fixedly connected to a movable plate 15, the corner of the movable plate 15 sliding against the outer wall of a support rod 12 fixed to the upper end of the base 11, and an upper pressure block 18 fixed to the lower end of the movable plate 15.
[0030] It should be noted that the telescopic end of the cylinder 14 extends downward, causing the movable plate 15 fixed thereon to move downward along the support rod 12. The corner of the movable plate 15 is slidably connected to the outer wall of the support rod 12, ensuring the stability and accuracy of the movement of the movable plate 15. As the movable plate 15 moves downward, the upper pressure block 18 fixed at the lower end of the movable plate 15 also moves downward.
[0031] In an optional embodiment, two fixing holes 181 are symmetrically provided on both sides of the lower end of the upper pressure block 18, and the two fixing holes 181 are respectively matched with two interfaces 202.
[0032] It should be noted that when the upper pressure block 18 continues to move downward, the two interfaces 202 are respectively inserted into the corresponding fixing holes 181 to further fix the flange housing 20, ensuring that the flange housing 20 will not move or shake during the testing process, thus ensuring the accuracy of the test.
[0033] In an optional embodiment, the upper end of the placement block 19 is provided with a fixing groove 191 that matches the sealing ring 203, and two vent holes 192 are symmetrically provided on both sides of the bottom of the fixing groove 191, and the two vent holes 192 correspond to the two interfaces 202 respectively.
[0034] The placement block 19 has an air intake channel, which includes an air inlet 193 and two air outlets 194. The air inlet 193 is located on one side of the placement block 19 and is connected to an air supply device through an external pipe. The two air outlets 194 are located at the bottom of two vent holes 192, and a pressure gauge is installed in each vent hole 192.
[0035] It should be noted that after the upper pressure block 18 is pressed down onto the flange housing 20 by adjusting the structure, the fixing hole 181, the flange housing 20, and the vent hole 192 form a sealed area. The gas supply equipment starts to work, and gas is injected into the air intake channel through the air inlet 193. After passing through the air intake channel, the gas enters the two vent holes 192 from the two air outlets 194 respectively, and then enters the interface 202 of the flange housing 20 through the vent holes 192, finally filling the interior of the flange housing 20. A pressure gauge is installed in the vent hole 192, which can monitor the pressure changes inside the flange housing 20 in real time. If the pressure value detected by the pressure gauge remains stable within a specified time, it indicates that the flange housing 20 has good airtightness. If the pressure value drops, it indicates that the flange housing 20 has air leakage and its airtightness is unqualified.
[0036] In an optional embodiment, an upper abutment rod 16 is fixed to the lower end of the movable plate 15, and a lower abutment rod 17 is fixed to the upper end of the base 11, with the upper abutment rod 16 corresponding to the lower abutment rod 17.
[0037] It should be noted that when the movable plate 15 moves the upper pressure block 18 downward to a certain position, the upper abutment rod 16 will contact the lower abutment rod 17, thereby limiting the movable plate 15 from moving further downward and preventing damage to the device and flange housing 20 due to excessive movement of the movable plate 15, thus playing a role in limit protection.
[0038] In an optional embodiment, the detection element 182 is a CCD camera.
[0039] It should be noted that the CCD camera can photograph and inspect the appearance of the flange housing 20, such as detecting whether there are defects such as scratches, cracks, and deformation on the surface of the flange housing 20. By analyzing and processing the photographed images, it can be determined whether the appearance quality of the flange housing 20 meets the requirements.
[0040] The above embodiment discloses a housing inspection device, in which the flange housing 20 to be inspected is placed on a placement block 19. A fixing groove 191 matching a sealing ring 203 is provided on the upper end of the placement block 19. The sealing ring 203 of the flange housing 20 is embedded in the fixing groove 191, completing the initial positioning. At this time, the interfaces 202 on both sides of the upper end of the bottom shell 201 of the flange housing 20 correspond to the two vent holes 192 on the placement block 19, respectively.
[0041] The cylinder 14, mounted on the upper end of the top seat 13, is activated, and the telescopic end of the cylinder 14 extends downward. The telescopic end of the cylinder 14 drives the movable plate 15 to move downward along the support rod 12.
[0042] As the movable plate 15 moves downward, the upper pressure block 18 fixed to the lower end of the movable plate 15 also moves downward. A CCD camera (inspection component 182) captures images of the flange housing 20. The captured images are uploaded to a computer via data cable or wireless transmission. The computer analyzes and processes the captured images to detect defects such as scratches, cracks, and deformation on the surface of the flange housing 20.
[0043] As the upper pressure block 18 continues to move downward, the two fixing holes 181 symmetrically opened on both sides of the lower end of the upper pressure block 18 match the interfaces 202 on both sides of the upper end of the bottom shell 201 of the flange housing 20, and the interfaces 202 are inserted into the corresponding fixing holes 181.
[0044] When the upper pressure block 18 is fully pressed down, the fixing hole 181, the flange housing 20 and the vent hole 192 together form a sealed area, creating conditions for airtightness testing.
[0045] The gas supply equipment starts working, filling the sealed area with gas through the air intake channel opened in the placement block 19. The air intake channel includes one air inlet 193 and two air outlets 194. The air inlet 193 is located on one side of the placement block 19 and is connected to the gas supply equipment through an external pipe; the two air outlets 194 are respectively located at the bottom of two vent holes 192. After the gas enters the air intake channel from the air inlet 193, it is distributed through the air intake channel and enters the two vent holes 192 from the two air outlets 194, and then enters the interface 202 of the flange housing 20 through the vent holes 192, finally filling the interior of the flange housing 20.
[0046] A pressure gauge is installed inside the vent 192 to monitor the pressure changes inside the flange housing 20 in real time. If the pressure value detected by the pressure gauge remains stable within a specified time, it indicates that the flange housing 20 has good airtightness and there is no gas leakage; if the pressure value drops, it indicates that the flange housing 20 has air leakage and its airtightness is unqualified.
[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
