Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection, in particular to an air-water dual detection machine. Background Art

[0002] Most leak inspections of workpieces use water immersion or soapy water spraying methods, and the tester's visual inspection is used to determine whether the workpiece has leaks. However, with the improvement of modern technology, the air tightness inspection standards for products have also been greatly improved. When the original inspection method is used for testing, since the gaps of existing workpieces are extremely small, even if the gas inside the workpiece is squeezed in water, it is difficult to leak from the gaps to produce bubbles, or the speed of bubble generation is slow, and it is difficult to determine whether the workpiece has leaks through the naked eye of the tester, and the inspection effect on the inner cavity of the workpiece is not good. Therefore, the existing inspection methods can no longer meet the needs of modern industry. For this reason, we propose a gas-water dual inspection machine. Utility Model Content

[0034] Based on the first embodiment, valves 18 are installed on the water inlet pipe 16 and the drain pipe 17 of this embodiment, and pipe joints are installed on one end of the water inlet pipe 16 and the drain pipe 17. The valve 18 is convenient for controlling the connection status of the water inlet pipe 16 and the drain pipe 17 with the high-strength glass cylinder 2. The outer wall of one side of the airtight detection box 1 is movably connected to the box door 28 through a hinge.

[0035] Working principle of this utility model:

[0036] Refer to the instruction manual Figure 1-5When the utility model is used, the box door 28 is first opened through the door handle 31, and the lifting plate 7 is driven to rise by the output extension of the electric push rod 6, and the lifting plate 7 is moved to the top of the high-strength glass cylinder 2, and the sealed cavity workpiece to be inspected is placed on the top of the lifting plate 7, and the two rotating handles 13 are rotated. The two rotating handles 13 drive the external threaded rotating rod 11 to rotate on the inner wall of the internal threaded sleeve 10, thereby driving the two external threaded rotating rods 11 to fix the cavity workpiece on the top of the lifting plate 7, and then the output shaft of the electric push rod 6 is contracted to drive the lifting plate 7 to the bottom inner wall of the high-strength glass cylinder 2, and water is injected into the interior of the high-strength glass cylinder 2 through the water inlet pipe 16, and the cavity workpiece is immersed in water. The output shafts of the first hydraulic push rod 22 and the second hydraulic push rod 23 are simultaneously lowered, and the output shaft of the second hydraulic push rod 23 drives the high-strength glass cylinder 4 to descend through the positioning plate 26 and the positioning ring 25. The high-strength glass cylinder 4 drives the high-strength glass cover 3 to descend and cover the top of the high-strength glass cylinder 2, the second docking ring 19 docks on the top of the first docking ring 14, and the sealing gasket 20 is squeezed on the inner wall of the sealing groove 15, so that the cavity workpiece is in a sealed container, and then the output shaft of the first hydraulic push rod 22 is driven to contract, and the first hydraulic push rod 22 drives the piston 24 to rise on the inner wall of the high-strength glass cylinder 4. At the same time, the air pressure in the high-strength glass cylinder 2 is checked in real time through the pressure gauge 27, so that a negative pressure is formed in the cavity of the high-strength glass cylinder 2 and the high-strength glass cover 3. Since the air pressure inside the cavity workpiece is higher than the air pressure inside the high-strength glass cylinder 2, if there is gas inside the cavity workpiece, the gas will be quickly squeezed out from the gap of the workpiece under the action of the air pressure. At this time, the tester can easily observe whether the cavity workpiece generates bubbles in the water. The utility model not only has high detection efficiency, but also has more accurate detection effect.

[0037] After the sealing performance test of the cavity workpiece is completed, the output shaft of the first hydraulic push rod 22 begins to descend, so that the air pressure in the high-strength glass cylinder 2 is consistent with the outside. At this time, the output shafts of the first hydraulic push rod 22 and the second hydraulic push rod 23 shrink at the same time, and the output shaft of the second hydraulic push rod 23 drives the high-strength glass cover 3 and the high-strength glass cylinder 4 to rise. The output shaft of the electric push rod 6 rises, and the cavity workpiece submerged in the water is lifted through the lifting plate 7. By rotating the rotating handle 13, the external threaded rotating rod 11 is driven to rotate, and the two extrusion plates 12 stop extruding the cavity workpiece, and the cavity workpiece is taken out of the utility model, and the water in the high-strength glass cylinder 2 is discharged through the drain pipe 17.

[0038] It should be noted that the above specific implementations are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art should understand that various modifications, equivalent substitutions, changes, etc. can be made to the present invention. However, as long as these changes do not deviate from the spirit of the present invention, they should be within the scope of protection of the present invention. In addition, some terms used in the specification and claims of this application are not restrictive, but are only for the convenience of description.
