Detailed Implementation

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example 1

[0028] like Figures 1-8 As shown, an airtight plugging device for processing aluminum plate workpieces includes: a mounting frame 1, with a column 11 connected to the top of the mounting frame 1, a placement plate 12 fixedly connected to the top of the column 11, a frame 13 fixedly installed around the periphery of the placement plate 12, a movable plate 14 provided on the top of one side of the mounting frame 1, two mounting rods a15 fixedly connected to the top of the movable plate 14, and a mounting plate 16 provided on one side of the two pairs of mounting rods a15; a plugging assembly, which is disposed on the mounting plate 16 and used to plug the workpiece; and a positioning assembly, which is disposed on the frame 13 and used to position the workpiece.

[0029] When inspecting a workpiece, the workpiece is manually placed on the placement plate 12 and positioned by the positioning component to keep it in the same state for inspection and prevent it from moving. Then, the sealing component can seal the holes and openings of the workpiece and inflate it with air. By observing whether the air pressure inside the workpiece decreases, the airtightness of the workpiece can be determined. Example 2

[0030] Based on Embodiment 1, the sealing assembly includes: mounting rod b2, airtight cover 21, connecting plate 22, sealing cylinder 23, sealing block 24, sealing strip 25, and inflation nozzle 26. Two mounting rods b2 are fixedly installed on one side of the mounting plate 16. The airtight cover 21 is fixedly installed at the bottom of the two mounting rods b2. The connecting plate 22 is fixedly connected to the top of the two mounting rods b2 respectively. Multiple sealing cylinders 23 are fixedly installed at the bottom of the connecting plate 22. The sealing block 24 is fixedly connected to the bottom of each sealing cylinder 23. Sealing strips 25 are provided on the top of the placement plate 12 and the four sides of the bottom of the airtight cover 21. Multiple inflation nozzles 26 are fixedly installed at the bottom inside the airtight cover 21.

[0031] The mounting frame 1 has multiple electric linear slide rails 4 fixedly installed on one side of its top. A movable plate 14 is mounted on the slide of the multiple electric linear slide rails 4. A lifting cylinder 41 is fixedly installed on the top of the movable plate 14. A pair of guide rails 42 are fixedly installed on one side of each of the two mounting rods a15. Two sliders 43 are slidably connected to the outside of each guide rail 42. Each slider 43 is connected to one side of the mounting plate 16. The top of the lifting cylinder 41 is connected to one side of the mounting plate 16. A bellows cover 44 is fixedly installed on one end of the mounting frame 1 near the electric linear slide rails 4. One side of the bellows cover 44 is connected to the movable plate 14. Side skirts 45 are provided on the outside of the two mounting rods a15. Multiple L-shaped pressure plates 46 are fixedly installed on one side of the mounting plate 16 near the bottom. Each L-shaped pressure plate 46 has a pressure block b47 fixedly installed at the bottom.

[0032] When inspecting the workpiece, the lifting cylinder 41 is activated. After activation, the lifting cylinder 41 retracts, causing the mounting plate 16 to move downwards. The mounting plate 16 then moves the slider 43 along the outside of the guide rail 42, allowing the mounting plate 16 to move smoothly. The mounting plate 16 also moves the mounting rod b2 and the airtight cover 21 downwards. The airtight cover 21 seals the opening of the workpiece by covering the sealing strip 25. Simultaneously, the L-shaped pressure plate 46 moves downwards, pressing the pressure block b47 against the workpiece. The sealing strip 25 on the placement plate 12 seals the bottom of the workpiece. Subsequently, the sealing cylinder 23 is activated, pushing the sealing block 24 downwards to block the vent hole on the airtight cover 21. Air is then injected into the workpiece through the inflation nozzle 26, increasing the internal air pressure. This is then used to inspect the internal components. The air pressure drop is used to determine the airtightness of the workpiece. After the test is completed, the lifting cylinder 41 and the sealing cylinder 23 are closed. After the sealing cylinder 23 is closed, it retracts and moves the sealing block 24 upward, so that the vent hole on the airtight cover 21 is connected to the outside, allowing the air pressure inside the workpiece to be released. Then, the lifting cylinder 41 is closed and pushed out, pushing the mounting plate 16 upward, so that the airtight cover 21 moves upward and separates from the workpiece. The L-shaped pressure plate 46 lifts the pressure block b47 to release the workpiece. In this way, holes and openings are sealed during the airtightness test. The electric linear slide rail 4 can drive the moving plate 14 to move. When the moving plate 14 moves, it will cause the bellows cover 44 to contract and extend. The bellows cover 44 and the side skirt cover 45 can activate the protection and shielding functions. Example 3

[0033] Based on Embodiment 1, the positioning assembly includes: a pressing cylinder a3, a torsion block 31, a pressing arm 32, a connecting rod 33, a pressing frame 34, a pressing block a35, and a positioning block 36. Several pressing cylinders a3 are fixedly installed around the perimeter of the frame 13. A torsion block 31 is fixedly connected to the top of each pressing cylinder a3. A pressing arm 32 rotates outside the torsion block 31. A connecting rod 33 is fixedly installed at the bottom of the pressing arm 32. A pressing frame 34 is fixedly installed at the bottom of the connecting rod 33. Two pressing blocks a35 are fixedly connected to the bottom of the pressing frame 34. Several positioning blocks 36 are fixedly installed at the edge of the top of the placement plate 12 near the sealing strip 25.

[0034] Among them, three mounting platforms 5 are fixedly installed on the top of the placement plate 12 near the opposite sides of the frame 13. Each mounting platform 5 is fixedly installed with a clamping cylinder b51. Each clamping cylinder b51 is rotatably connected to a pressure rod 52. Each pressure rod 52 is fixedly connected to a clamping block 53 at the bottom. Each of the two opposite mounting platforms 5 is fixedly installed with a symmetrically arranged placement frame 54. A crossbar 55 is provided between the two opposite placement frames 54. Multiple pressure strips 56 are fixedly connected to the bottom of the crossbar 55. Each of the crossbar 55 is fixedly connected to two handles 57 at the top.

[0035] When placing the workpiece, place it on the placement plate 12 and between several positioning blocks 36 to position it and prevent it from moving. Then, place both ends of the crossbar 55 into the two opposite placement frames 54, ensuring that the multiple pressure strips 56 at the bottom of the crossbar 55 face downwards and that the two handles 57 on the crossbar 55 are easy to pick up. This causes the clamping cylinder b51 to retract, which in turn moves the pressure rod 52 and the clamping block 53 downwards. The pressure rod 52 moves downwards and inserts into the limit rod at the top of the clamping cylinder b51, preventing it from rotating. This causes the clamping block 53 to press the crossbar 55, thus clamping the workpiece. To prevent the crossbar 55 from loosening, the clamping cylinder a3 is retracted, causing the clamping arm 32, connecting rod 33, and clamping frame 34 to deflect towards the workpiece, so that the clamping block a35 presses down on the edge of the workpiece, thus clamping the workpiece to prevent loosening. When it is necessary to release the workpiece, the clamping cylinders a3 and b51 are pushed out. The clamping cylinder a3 pushes out the clamping rod 52, which drives the clamping block 53 to move upward, thereby releasing the fixation of the crossbar 55. Then the crossbar 55 is taken out of the placement frame 54. The clamping cylinder b51 pushes out, causing the clamping arm 32, connecting rod 33, and clamping frame 34 to deflect, so that the clamping block a35 releases the workpiece, thereby releasing the fixation of the workpiece. The workpiece is then taken out, thus completing the disassembly.
