[0031] Example

[0032] Please see Figures 1 to 3 As shown, this embodiment provides a multi-chamber plugging testing device, which includes a frame 10, a testing component 20, a first limiting component 30, a second limiting component 40, a third limiting component 50, a first plugging component 60, and a second plugging component 70. An installation platform 11 is provided on the frame 10. The testing component 20 includes a testing station 21, a guide component 22, and a testing component (not shown in the figure). The testing station 21 is located on the installation platform 11, the guide component 22 is located on the testing station 21, and the testing component is located below the testing station 21. The measuring station 21 is located inside the first limiting component 30. The second limiting component 40 is spaced above the first limiting component 30. The third limiting component 50 is spaced on the first side of the first limiting component 30 along the first horizontal direction. The first sealing component 60 is spaced on the second side of the first limiting component 30 along the first horizontal direction. The second sealing component 70 is located on the third side along the second horizontal direction of the first limiting component 30. The first sealing component 60 is configured to seal multiple pores inside the workpiece to form multiple chambers for sealing detection.

[0033] It can be seen that, through the cooperation of the frame 10, detection component 20, first limit component 30, second limit component 40, third limit component 50, first sealing component 60 and second sealing component 70, the positioning stability of the workpiece is high when sealing different air ports and pores of the workpiece, thus improving the detection efficiency.

[0034] In one embodiment, the first sealing component 60 includes a base 61, a first driving member 62, a second driving member 63, a third driving member 64, a first sealing member 65, and a second sealing member 66. The base 61 is mounted on the mounting platform 11. The fixed end of the first driving member 62 is mounted on the base 61, and the movable end of the first driving member 62 is provided with a first mounting plate 67. The fixed end of the second driving member 63 is fixedly mounted on the first mounting plate 67, and the movable end of the second driving member 63 is provided with a second mounting plate 68. The fixed end of the third driving member 64 is located on the first side of the second mounting plate 68. The first sealing member 65 is located on the second side opposite to the first side of the second mounting plate 68. The movable end of the third driving member 64 extends out of the second mounting plate 68 and is mounted with the first sealing member 65. The second sealing member 66 is located on the driving end of the third driving member 64.

[0035] Specifically, both the first drive component 62 and the third drive component 64 are cylinders.

[0036] Specifically, the first sealing element 65 includes a first sealing surface and a second sealing surface.

[0037] As can be seen, the first sealing component 60 adopts a structure combining the first driving component 62, the second driving component 63, the third driving component 64, the first sealing component 65, and the second sealing component 66. The layered driving mechanism enables multi-dimensional and high-precision position adjustment, allowing the first sealing component 65 and the second sealing component 66 to accurately move to the corresponding positions of the air holes in the workpiece for sealing. In cases where multiple air holes inside the workpiece need to be sealed, it can flexibly adapt to the spatial layout of different air holes, accurately complete the sealing operation, improve the success rate and sealing effect of sealing, and thus ensure the accuracy of subsequent testing.

[0038] In one implementation, the movable end of the first sealing component 60 is positioned toward the detection station 21. The first sealing component 60 is configured to seal the first air port, the first air hole, and the second air hole arranged sequentially from the outside to the inside of the workpiece. The second driving component 63 includes two cylinders symmetrically arranged on the first mounting plate 67.

[0039] As can be seen, the first sealing component 60 seals the first air port, the first air hole, and the second air hole arranged sequentially from the outside to the inside of the workpiece. This targeted sealing setting can orderly seal the relevant air holes according to the specific air hole distribution and chamber formation requirements of the workpiece, ensuring that multiple chambers can be accurately formed according to the design requirements. This facilitates independent and effective sealing testing of each chamber, improving the adaptability of the entire testing process to the actual structure of the workpiece. In addition, the second driving component 63 uses two cylinders symmetrically arranged on the first mounting plate 67. The symmetrical cylinder structure can distribute the driving force more evenly on the second mounting plate 68, avoiding problems such as skewness and jamming during the movement of the first sealing component 65 and the second sealing component 66 due to uneven force on one side. This ensures that the sealing action is executed smoothly and accurately, further enhancing the reliability of the sealing operation.

[0040] In one embodiment, two guide rails 610 are inclinedly arranged on the base 61, and sliders 611 are provided on both guide rails 610. The bottoms of the first mounting plate 67 and the second mounting plate 68 are both arranged on the sliders 611.

[0041] As can be seen, two guide rails 610 are inclinedly arranged on the base 61 and equipped with a slider 611. The bottom of the first mounting plate 67 and the second mounting plate 68 are set on the slider 611, which can provide precise guidance for the movement of the first mounting plate 67, the second mounting plate 68, the first sealing member 65 and the second sealing member 66, ensuring that they move smoothly along the predetermined inclined trajectory, reducing friction and shaking during the movement, and enabling the first sealing member 65 and the second sealing member 66 to reach the designated sealing position more smoothly and accurately, thereby improving the stability and accuracy of the first sealing assembly 60.

[0042] In one embodiment, the first limiting component 30 includes a limiting frame 31, a fourth driving member 32, a first limiting member 33, and a third sealing member 34. The limiting frame 31 is sleeved on the testing station 21. The fourth driving member 32 is disposed on the third side along the second horizontal direction of the first limiting component 30. The moving end of the fourth driving member 32 is provided with a third mounting plate 35. The first limiting member 33 and the third sealing member 34 are both disposed on the third mounting plate 35.

[0043] Specifically, the fourth driving component 32 is configured to drive the third mounting plate 35 close to the inspection station 21, thereby abutting the third sealing component 34 against the third air port of the workpiece and abutting the first limiting component 33 against the workpiece, so as to fix the workpiece on the inspection station 21.

[0044] As can be seen, the first limiting component 30, through the cooperation of the limiting frame 31, the fourth driving component 32, the first limiting component 33 and the third sealing component 34, and the fourth driving component 32 driving the third mounting plate 35 to move, thereby causing the third sealing component 34 to abut against the third air port of the workpiece and the first limiting component 33 to abut against the workpiece, can effectively fix the workpiece from multiple parts, firmly fix the workpiece on the detection station 21, prevent the workpiece from shifting or shaking during sealing, detection and other operations, ensure that subsequent operations can be carried out accurately and stably, and improve the reliability of the detection results.

[0045] In one embodiment, the second limiting component 40 includes a fifth driving member 41 and a plurality of second limiting members 42. The fifth driving member 41 is disposed on the top of the frame 10, the moving end of the fifth driving member 41 is disposed downward, and the moving end of the fifth driving member 41 is provided with a fourth mounting plate 43. The plurality of second limiting members 42 are all disposed on the fourth mounting plate 43.

[0046] Specifically, the fixed end of the fifth driving component 41 is set on the mounting bracket above the inspection station 21, and guide rods are provided on both sides of the fifth driving component. The guide rods are movably set on the mounting bracket, and the movable end of the guide rods is set on the fourth mounting plate 43.

[0047] Specifically, the fifth driving member 41 is configured to drive the fourth mounting plate 43 to move downward, thereby bringing the bottom end of the second limiting member 42 into contact with the workpiece to fix the workpiece on the inspection station 21.

[0048] As can be seen, the second limiting component 40 uses the fifth driving component 41 to drive multiple second limiting components 42, which can fix the workpiece from top to bottom. It works together with other limiting components from different directions to form a multi-directional fixing effect, which further enhances the stability of the workpiece on the detection station 21, avoids unnecessary movement of the workpiece in various directions, and ensures that the workpiece is always in an accurate position during the entire detection and sealing operation, which helps to improve the accuracy of detection and the sealing performance.

[0049] In one embodiment, the third limiting component 50 includes a limiting post 51 and a limiting block 52. The limiting post 51 is fixedly installed on the second side of the first limiting component 30 along the first horizontal direction, and the limiting block 52 is spaced apart on the outside of the limiting post 51. Both the limiting post 51 and the limiting block 52 are configured to limit and fix the workpiece.

[0050] As can be seen, the third limiting component 50, through the setting of the limiting post 51 and the limiting block 52, limits and fixes the workpiece from a specific horizontal direction, further constrains the position of the workpiece, prevents the workpiece from shifting or misaligning, improves the limiting system for the workpiece, and ensures the accuracy and stability of the workpiece's position during the detection process.

[0051] In one embodiment, the second sealing assembly 70 includes a sixth driving member 71 and a seventh driving member 72. The moving end of the sixth driving member 71 is provided with a fourth sealing member 73, and the moving end of the seventh driving member 72 is provided with a fifth sealing member 74. The sixth driving member 71 and the seventh driving member 72 are respectively configured to seal specific holes in the workpiece through the fourth sealing member 73 and the fifth sealing member 74.

[0052] As can be seen, the second sealing component 70 uses the sixth driving component 71 and the seventh driving component 72 to drive the fourth sealing component 73 and the fifth sealing component 74 to seal specific holes in the workpiece. It can perform independent sealing operations for specific holes with different positions and functions on the workpiece. It can flexibly select which holes to seal according to different detection requirements to form the required chamber structure, which increases the flexibility of the equipment in sealing operation and its adaptability to different workpieces and different detection scenarios.

[0053] In one embodiment, a control device 12 is provided at the bottom of the frame 10. The control device 12 is electrically connected to the detection component 20, the first limiting component 30, the second limiting component 40, the third limiting component 50, the first blocking component 60, and the second blocking component 70.

[0054] As can be seen, a control device 12 is installed on the top of the frame 10 and electrically connected to the detection component 20, the first limit component 30, the second limit component 40, the third limit component 50, the first blocking component 60, and the second blocking component 70. This enables centralized control of the detection component 20, the first limit component 30, the second limit component 40, the third limit component 50, the first blocking component 60, and the second blocking component 70. Operators can conveniently coordinate the working sequence and action parameters of each component through the control device 12, thereby improving the automation level of equipment operation.

[0055] As one implementation, a lighting lamp 13 is also provided on the top of the rack 10.

[0056] As can be seen, the lighting lamp 13 installed at the top of the frame 10 provides sufficient light when the equipment performs sealing detection on the workpiece, especially in some working environments where the light may be dim. This light illuminates the detection station 21 and the area where the workpiece is located, making it easier for operators to observe the working status of each component, the sealing status of the workpiece, and related phenomena during the detection process. This helps to detect problems in a timely manner, ensure the accuracy of the detection operation, and also improves the safety of the operation process.
