Technical Field

[0001] The utility model specifically relates to the technical field of air tightness detection for buildings, in particular to an air tightness tooling test module. Background Art

[0002] The airtightness detection test is mainly to check whether there is leakage in the connection parts of the container. The pressure vessels with extremely toxic or highly hazardous media or the pressure vessels that are not allowed to have trace leakage in the design must be subjected to airtightness test. Many products in our lives need to be tested for airtightness. The airtightness test is applied to the rigorous integrity assessment of aircraft, automobile shells, ships and internal containers. It is a quality control application developed for the transportation department, military department and basic industry to improve the airtightness of vehicles, aircraft, ships, etc. The ultrasonic transmitter is placed inside the container. Due to the characteristics of ultrasonic waves, these waves can penetrate small holes. Using ultrasonic detection system to detect outside the container, the inspector can quickly find the source of the defect, which may become potential leaks or wind noise points.

The other end of the hinge 22 is installed at the edge of the upper support frame 2. A probe 23 is fixedly installed between the cover plate 20 and the sealing upper die 21;

[0038] A lower support frame 3 is fixedly installed below the upper support frame 2, and two sets of placing lower dies 30 are placed at the top end of the lower support frame 3. A sealing groove 308 is formed at the top edge of the placing lower die 30, and a sealing ring is installed inside the sealing groove 308. A hydraulic rod 31 is installed between the upper support frame 2 and the lower support frame 3;

[0039] The bottom end of the lower support frame 3 is fixedly connected to a support rod 41, and the bottom end of the support rod 41 is fixedly connected to a limit frame 4. A limit hole 40 is formed through the center of the limit frame 4;

[0040] A jacking frame 50 is arranged below the limit hole 40, and a jacking cylinder 5 is installed at the bottom end of the jacking frame 50.

[0041] In this embodiment, two sets of pulleys 110 are arranged at the position on the inner wall of the side plate 11, and the number of each set of pulleys 110 is several. The upper support frame 2 is located between the two sets of pulleys 110, and the pulleys 110 are slidably connected to the two end faces of the upper support frame 2.

[0042] In this embodiment, the cover plate 20 is attached to the lower support plate 101.

[0043] In this embodiment, the probe 23 is one of a pneumatic detection probe or a gas detection probe.

[0044] In this embodiment, a corresponding hole is penetrated through at the position of the sealing upper die 21 corresponding to the placement hole 301.

[0045] In this embodiment, a plurality of placement holes 301 are formed inside the placement lower die 30, and ventilation holes 302 are penetrated through both sides of the placement holes 301. A baffle 303 is arranged at the position of the placement hole 301 close to the air outlet end of the ventilation hole 302.

[0046] In this embodiment, an air inlet 304 and an air outlet 305 are respectively penetrated through one end face of the placement lower die 30, and a first communication air hole 306 and a second communication air hole 307 are formed at the positions corresponding to the air inlet 304 and the air outlet 305 at the other end of the placement lower die 30. The first communication air hole 306 and the second communication air hole 307 are communicated with each other.

[0047] The working principle of the present utility model is as follows: When in use, on the basis of the whole being placed stably, the upper support frame 2 is pulled. At this time, the whole operation unit is pulled out under the action of the two sets of pulleys 110. After being pulled out, the sealing upper die 21 is opened through the hinge 22;

[0048] Meanwhile, the placement lower die 30 is exposed. An article to be detected is placed in the placement hole 301 of the placement lower die 30, and the sealing upper die 21 is closed. At this time, the article to be detected is placed inside the operation cavity formed by the placement hole 301 and the hole inside the sealing upper die 21;

[0049] Then, push the upper support frame 2 back to its original position and activate the lifting cylinder 5. Drive the lifting frame 50 to move upward through the lifting cylinder 5. When passing through the limit hole 40 at the limit frame 4 for limiting, the upward movement of the lifting frame 50 pushes the lower support frame 3 to move upward. At this time, the lower support frame 3 compresses the hydraulic rod 31 under force, resulting in the upward movement of the placing lower die 30 located on the lower support frame 3 to tightly press the sealing upper die 21. Meanwhile, under the action of the sealing groove 308 and the sealing ring, the working environment can be effectively sealed. At the same time, introduce gas into the air inlet 304 of the placing lower die 30, and use the baffle 303 to block the gas to a certain extent, so that the gas is in full contact with the item to be detected. Finally, observe the internal air pressure change through the probe 23. If the air pressure is constant, the airtightness of the item to be detected is good; otherwise, if the internal air pressure fluctuates within a certain period of time, the result is the opposite.
