Detailed implementation manners

[0023] The following are specific embodiments of the present utility model in combination with the drawings, and the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0024] It should be noted that all the directional indications (such as up, down, left, right, front, back,...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0025] As Figures 1 to 4 shown, a general - purpose air - tightness testing device includes a frame 100, a first plate member 110, a second plate member 120, a first plugging assembly 200, a workpiece placement plate 300, a second plugging assembly 400, a guiding assembly 500, and a connecting assembly 600.

[0026] As Figures 1 to 4 shown, a general - purpose air - tightness testing device includes:

[0027] A frame 100, on which a first plate member 110 and a second plate member 120 are provided. There is a gap between the first plate member 110 and the second plate member 120, and a limiting portion 121 is detachably provided on the second plate member 120;

[0028] The first sealing assembly 200 is movably disposed on the first plate member 110 and moves toward the second plate member 120.

[0029] The workpiece placement plate 300 is detachably disposed on the second plate member 120. It includes a fixing groove 310 that forms a snap connection with the limiting portion 121. When the fixing groove 310 is snap-connected to the limiting portion 121, the limiting portion 121 limits the movement of the workpiece placement plate 300 in the X-axis and Y-axis directions. This effectively prevents the workpiece placement plate 300 from shaking left and right, thus ensuring the stability during the airtightness test. At the same time, the workpiece placement plate 300 can be quickly installed and disassembled by longitudinal movement in the Z-axis direction, thereby realizing the quick replacement of workpieces 700 of different models, greatly improving the test efficiency and the versatility of the test device.

[0030] As Figures 1 to 4 shown, in this embodiment, the frame 100 includes a plurality of cross bars 101 and vertical bars 102. The cross bars 101 are arranged in a rectangle and form three rectangular frames, and the three rectangular frames are connected by the vertical bars 102, serving as the support components of the test device.

[0031] In this embodiment, the frame 100 is provided with a first plate member 110 and a second plate member 120 arranged longitudinally. The first plate member 110 and the second plate member 120 are rectangular, and there is a gap between them to form an airtightness test space so that the workpiece 700 can be subjected to an airtightness test in the test space.

[0032] In this embodiment, the first sealing assembly 200 is movably disposed on the first plate member 110. The first sealing assembly 200 moves vertically toward the second plate member 120 to seal the workpiece 700 located on the second plate member 120.

[0033] In this embodiment, the first sealing assembly 200 includes a first driving member 210 vertically connected to the first plate member 110, and a first sealing plate 220 detachably connected to the output end of the first driving member 210. The first sealing plate 220 is rectangular. Its detachable connection to the output end of the first driving member 210 enables convenient installation and disassembly, allowing the user to replace the first sealing plate 220 of different models according to the usage requirements, thereby further improving the versatility of the test device.

[0034] Preferably, in this embodiment, the first driving member 210 is a driving cylinder, and the output end of its telescopic rod is threadedly connected to the first sealing plate 220 through a connecting assembly 600. The connecting assembly 600 includes a connecting seat 610 detachably connected to the first sealing plate 220, and a connecting member 620 threadedly connected to the connecting seat 610 and the output end of the first driving member 210 respectively. While realizing the detachable connection of the first sealing plate 220, the overall structure of the testing device is effectively simplified.

[0035] To ensure the force balance of the first sealing plate 220, in this embodiment, two sets of the first driving member 210 and the connecting assembly 600 are provided.

[0036] In this embodiment, a guiding assembly 500 is further provided between the first plate member 110 and the first sealing plate 220. The guiding assembly 500 extends along the moving direction of the first sealing plate 220 to guide the moving direction of the first sealing plate 220. It ensures the linear movement of the first sealing plate 220, improves the accuracy and stability of the sealing operation, and thus enhances the working efficiency and testing accuracy of the overall testing device.

[0037] Preferably, in this embodiment, the guiding assembly 500 includes two sets of guiding rods 510 perpendicularly connected to the first plate member 110 and the first sealing plate 220 respectively. Among them, one end of the guiding rod 510 is detachably connected to the first sealing plate 220, and the other end passes through the first plate member 110 and forms a movable connection with the first plate member 110.

[0038] In this embodiment, a first silicone plate 230 is further provided on the side of the first sealing plate 220 facing away from the first driving member 210. The first silicone plate 230 is adapted to the size of the first sealing plate 220, and an air vent 240 is further provided on the first sealing plate 220. The air vent 240 extends along a direction perpendicular to the first sealing plate 220 and sequentially penetrates through the first sealing plate 220 and the first silicone plate 230 for inflation operation, so as to perform an airtightness test on the workpiece 700.

[0039] In this embodiment, a limiting portion 121 is detachably provided on the second plate member 120. The limiting portion 121 is used to limit the workpiece placing plate 300 in the X-axis and Y-axis directions. While preventing the workpiece placing plate 300 from moving, it facilitates the quick installation and disassembly of the workpiece placing plate 300, and effectively improves the replacement efficiency of the workpiece placing plate 300.

[0040] In this embodiment, the workpiece placement plate 300 is rectangular, horizontally arranged on the second plate member 120, and coaxially arranged with the first plugging component 200. It includes a fixing groove 310 that forms a snap connection with the limiting portion 121. When the fixing groove 310 is snap-connected to the limiting portion 121, the limiting portion 121 limits the movement of the workpiece placement plate 300 in the X-axis and Y-axis directions. Since the limiting portion 121 does not limit the workpiece placement plate 300 in the Z-axis direction, the workpiece placement plate 300 can be quickly installed and disassembled by longitudinal movement.

[0041] In this embodiment, there are at least two groups of the fixing grooves 310, which are respectively located on the adjacent sides or opposite sides of the workpiece placement plate 300, and there are also at least two groups of the limiting portions 121, which correspond to the positions of the fixing grooves 310. This avoids the situation where a single fixing groove 310 can only limit the X-axis or Y-axis, enhances the stability of the placement of the workpiece placement plate 300, and at the same time ensures the accurate positioning of the workpiece 700.

[0042] Preferably, in this embodiment, the two groups of fixing grooves 310 are respectively arranged on the opposite sides of the workpiece placement plate 300 and are arranged in alignment to improve the convenience of installing the workpiece placement plate 300.

[0043] In this embodiment, each group of fixing grooves 310 includes a first limiting edge 311, a second limiting edge 312, and a third limiting edge 313 arranged in a U-shaped configuration. Each group of limiting portions 121 is in the shape of a rectangular strip and is detachably connected to the second plate member 120 by screws. When the fixing groove 310 is snap-connected to the limiting portion 121, the limiting portion 121 abuts against the first limiting edge 311, the second limiting edge 312, and the third limiting edge 313 respectively. The all-round contact between the limiting portion 121 and the fixing groove 310 provides more comprehensive limiting support, thereby enhancing the stability of the workpiece 700 during the test process and improving the test accuracy.

[0044] In this embodiment, there are also two groups of handles 320 on the workpiece placement plate 300. The handles 320 are perpendicularly connected to the workpiece placement plate 300 and are located on both sides of the workpiece placement plate 300. This enables the user to achieve the longitudinal movement of the workpiece placement plate 300 by lifting the handles 320, greatly simplifies the operation of moving the workpiece placement plate 300, makes the installation and removal of the workpiece placement plate 300 more convenient, and effectively improves the use efficiency.

[0045] To ensure the positioning of workpiece 700 and its stability after installation, in this embodiment, four groups of limiting strips 330 are further provided on the workpiece placement plate 300. The limiting strips 330 are arranged in a rectangular shape and form a receiving groove for fixing the workpiece 700. The design of the limiting strips 330 and the receiving groove provides additional positioning assistance for the workpiece 700, enhances the positioning accuracy of the workpiece 700, and can prevent the workpiece 700 from moving on the workpiece placement plate 300, effectively reducing the test error.

[0046] In this embodiment, the limiting strip 330 is detachably connected to the workpiece placement plate 300. Preferably, the limiting strip 330 is detachably connected to the workpiece placement plate 300 by screws, enabling the user to flexibly adjust according to the actual size of the workpiece 700, effectively enhancing the versatility and adaptability of the test device.

[0047] In this embodiment, a number of support seats 340 are detachably provided on the workpiece placement plate 300. The support seats 340 are arranged on the adjacent sides of the limiting strips 330, and a second plugging assembly 400 is movably provided on the support seats 340 to plug the holes on the side of the workpiece 700. The design of the support seats 340 enables the user to freely increase or decrease the number of support seats 340 and the second plugging assembly 400 according to the number of side holes of different workpieces 700 on the one hand, and enables the user to flexibly adjust the support seats 340 at different heights according to the plugging requirements at different heights on the other hand, further improving the versatility of the test device and enhancing the flexibility and adaptability of the test device.

[0048] In this embodiment, the second plugging assembly 400 includes a second driving member 410 and a second plugging plate 420. The second driving member 410 is detachably connected to the support seat 340, and the second plugging plate 420 is detachably provided at the output end of the second driving member 410, so that the user can replace the second plugging plate 420 with different specifications according to the usage requirements.

[0049] Preferably, in this embodiment, the second driving member 410 is a driving cylinder, and the second plugging plate 420 is in a boss shape. Among them, a second silicone plate 430 is provided on the second plugging plate 420 in the direction away from the second driving member 410, effectively ensuring the airtightness of the connection between the second plugging plate 420 and the workpiece 700, and thus ensuring the accuracy of the airtightness test of the workpiece 700.
