Description

Technical Field

[0001] This utility model relates to the field of helium mass spectrometry leak detection technology, specifically a helium leak detection tooling for TR components. Background Technology

[0002] In the field of modern radar technology, the TR module is a core component of phased array radar, and its performance directly determines the effectiveness of key functions such as signal transmission and reception and power amplification of the radar system. The airtightness of the TR module is an important indicator affecting its performance and reliability. If there are airtightness defects, external moisture and impurities will enter the module, leading to corrosion of electronic components, performance degradation, and in severe cases, even radar system failure.

[0003] Most commercially available helium leak detection fixtures for TR components employ traditional sealing structures, commonly using ordinary rubber sealing rings as the core sealing element. These ordinary rubber sealing rings typically achieve sealing through simple compression deformation. During the installation and use of the fixture, due to repeated disassembly and assembly, uneven stress, and changes in internal pressure during testing, the sealing rings are prone to loosening. Once the sealing rings loosen, even tiny gaps that are difficult to detect with the naked eye can become channels for helium leakage. Helium leakage not only interferes with the accuracy of the test, leading to misjudgments and allowing unqualified products to enter the next production stage, but also reduces helium testing efficiency and increases testing time costs. Utility Model Content

[0004] The purpose of this invention is to provide a helium leak detection fixture for TR components to solve the problems mentioned in the background art. To solve the above technical problems, this invention is achieved through the following technical solution:

[0005] This utility model is a helium leak detection fixture for TR components, comprising:

[0006] A tooling base plate and a cover plate, wherein the cover plate is located on top of the tooling base plate;

[0007] The clamping component includes a fixed plate, a top plate, a fastening groove, a spring, a fastening strip, a support frame, and a vertical rod. The fixed plate is located on the lower part of both sides of the outer surface of the tooling base plate. The vertical rod is set at one end of the top of the fixed plate. The spring is wound around the outer surface of the vertical rod. The support frame is movably connected through the outer surface of the vertical rod. The top plate is fixed at the top between the two support frames. The fastening strip is set at the upper end of one side of the outer surface of the top plate. The fastening groove is opened at both ends of the top of the cover plate, and the fastening strip is embedded in the inside of the fastening groove.

[0008] Furthermore, a vertical plate is fixedly connected to one end of the outer surface of the fixed plate, and a movable groove is provided inside the vertical plate. A movable block is fixed to one end of the outer surface of the support frame, and the movable block is movably connected inside the movable groove.

[0009] Furthermore, support blocks are provided at both ends of the outer surface of the tooling base plate, and a guide rod is provided between the two support blocks. The guide rod is externally movably connected to the guide ring.

[0010] Furthermore, a support bar is fixedly connected between the fixing plate and the guide ring. One end of the outer surface of the support bar is provided with an internal threaded ring, and a threaded rod is threadedly connected to the middle of the internal threaded ring. A handle is fixedly connected to the outer end of the threaded rod.

[0011] Furthermore, the top of the cover plate has several through holes, the bottom of the cover plate is bonded with a sealing gasket, the top of the tooling base plate has an inner groove, and the sealing gasket is embedded in the inner groove.

[0012] Furthermore, it also includes a reinforcing component, which includes a rotating shaft and a clamping frame. The rotating shaft is located at the middle of both ends of the outer surface of the cover plate, and the clamping frame is rotatably connected to the outer surface of the rotating shaft and clamped between two fastening plates.

[0013] Furthermore, a rubber block is adhered to the upper part of one end of the outer surface of the clamping frame, and the rubber block is blocked between the two fastening plates.

[0014] This utility model has the following beneficial effects:

[0015] This invention, by incorporating a clamping component, embeds the sealing gasket within the inner groove of the fixture base plate. A cover plate seals the top of the fixture base plate. The movement of the guide ring outside the guide rod pushes the fixing plate against both sides of the fixture base plate. The spring force then lifts the support frame upwards, pressing the fastening strip into the fastening groove. This creates a multi-directional, uniform, and continuous clamping force on the sealing gasket, overcoming the vulnerability of the sealing ring to loosening under external forces in traditional sealing structures. It significantly reduces the risk of gasket displacement and loosening, fundamentally solving the sealing failure problem caused by loose sealing elements and improving testing accuracy.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-3 As shown, this utility model is a helium leak detection tooling for TR components, comprising:

[0029] Tooling base plate 11 and cover plate 12, wherein the cover plate 12 is located on the upper part of tooling base plate 11;

[0030] The clamping component includes a fixed plate 21, a top plate 22, a fastening groove 23, a spring 24, a fastening strip 25, a support frame 26, and a vertical rod 27. The fixed plate 21 is located at the lower part of both sides of the outer surface of the tooling base plate 11. The vertical rod 27 is set at one end of the top of the fixed plate 21. The spring 24 is wrapped around the outer surface of the vertical rod 27. The support frame 26 is movably connected through the outer surface of the vertical rod 27. The top plate 22 is fixed at the top between the two support frames 26. The fastening strip 25 is set at the upper end of one side of the outer surface of the top plate 22. The fastening groove 23 is opened at both ends of the top of the cover plate 12. The fastening strip 25 is embedded in the inside of the fastening groove 23.

[0031] The sealing gasket 14 is embedded in the inner groove 15 of the tooling base plate 11, and the cover plate 12 is sealed to the top of the tooling base plate 11. The support frame 26 is lifted upward by the elastic force generated by the spring 24, so that the fastening strip 25 is pressed into the fastening groove 23, thereby forming a multi-directional, uniform and continuous fastening force on the sealing gasket 14. This changes the situation in the traditional sealing structure where the sealing ring is easily loosened by external force, and greatly avoids the displacement and loosening of the sealing gasket 14. It fundamentally solves the problem of sealing failure caused by loose sealing elements and improves the accuracy of testing.

[0032] A vertical plate 28 is fixedly connected to one end of the outer surface of the fixed plate 21. A movable groove 29 is provided inside the vertical plate 28. A movable block 291 is fixed to one end of the outer surface of the support frame 26. The movable block 291 is movably connected inside the movable groove 29.

[0033] When the support frame 26 is lifted upwards, the moving block 291 will move inside the moving groove 29 at the same time, which will guide the support frame 26.

[0034] Support blocks 32 are provided at both ends of the outer surface of the tooling base plate 11, and a guide rod 33 is provided between the two support blocks 32. The guide rod 33 is externally movably connected to the guide ring 34.

[0035] The movement of the guide ring 34 outside the guide rod 33 can push the fixing plate 21 to fit against both sides of the tooling base plate 11.

[0036] A support bar 31 is fixedly connected between the fixed plate 21 and the guide ring 34. One end of the outer surface of the support bar 31 is provided with an internal threaded ring 35. A threaded rod 36 is threadedly connected to the middle of the internal threaded ring 35. A handle 37 is fixedly connected to the outer end of the threaded rod 36.

[0037] Turning the handle 37 drives the threaded rod 36 to rotate, so that the threaded rod 36 is clamped outside the guide rod 33, thus fixing the position of the fixed plate 21 after it has been moved.

[0038] The top of the cover plate 12 has several through holes 13, and the bottom of the cover plate 12 is bonded with a sealing gasket 14. The top of the tooling base plate 11 has an inner groove 15, and the sealing gasket 14 is embedded in the inner groove 15.

[0039] The sealing gasket 14 is embedded in the inner groove 15 of the tooling base plate 11, and the cover plate 12 is sealed to the top of the tooling base plate 11.

[0040] The working principle involves embedding the sealing gasket 14 into the inner groove 15 at the top of the fixture base plate 11. Then, the guide ring 34 slides along the guide rod 33, pushing the fixing plate 21 to fit against both sides of the fixture base plate 11. Rotating the handle 37 drives the threaded rod 36 to rotate, so that the threaded rod 36 is tightly clamped outside the guide rod 33, completing the fixation of the fixing plate 21. At this time, the spring 24 generates an upward elastic force on the support frame 26, driving the fastening strip 25 to embed into the fastening groove 23 of the fixture base plate 11, further pressing the sealing gasket 14. This ensures that the cover plate 12 and the top of the fixture base plate 11 form a highly sealed space, avoiding the risk of leakage due to loose sealing rings. This creates a multi-directional, uniform, and continuous fastening force on the sealing gasket 14, changing the situation in traditional sealing structures where sealing rings are easily loosened by external forces. This greatly avoids the displacement and loosening of the sealing gasket 14, fundamentally solving the problem of sealing failure caused by loose sealing elements and improving the accuracy of testing.

[0041] Next, one end of the inlet pipe is connected to an external helium gas source, and the other end extends through the through hole 13 of the cover plate 12 to the inside of the tooling base plate 11. After the helium gas source is turned on, helium is injected into the sealed space inside the tooling base plate 11 through the inlet pipe. Since helium molecules are extremely small, they can penetrate into tiny gaps that are difficult to see with the naked eye. If there is a leak in the tooling base plate 11, helium will escape from there. Finally, one end of the outlet pipe is connected to the sealed space inside the tooling base plate 11, and the other end is connected to a helium mass spectrometer leak detector.

[0042] Please see Figure 1 , Figure 4 As shown, this embodiment, based on the above embodiment, further includes:

[0043] The reinforcing component includes a rotating shaft 41 and a clamping frame 42. The rotating shaft 41 is located at the middle of both ends of the outer surface of the cover plate 12, and the clamping frame 42 is rotatably connected to the outer surface of the rotating shaft 41 and clamped between two fastening plates.

[0044] After the fastening strips 25 at both ends are pressed into the inside of the fastening groove 23, the clamping frame 42 rotates through the rotating shaft 41, so that the clamping frame 42 is clamped between the two fastening strips 25, thus pressing the position between the two fastening strips 25 again.

[0045] A rubber block 43 is glued to the upper part of one end of the outer surface of the clamping frame 42, and the rubber block 43 blocks between the two fastening plates.

[0046] When the clamping frame 42 rotates, it squeezes the rubber block 43, causing the rubber block 43 to be engaged between the two fastening strips 25 at one end, thus preventing the clamping frame 42 from loosening.

[0047] Working principle: After the fastening strips 25 at both ends are fully pressed into the fastening grooves 23, the operator rotates the clamping frame 42, allowing it to rotate flexibly around the rotating shaft 41, clamping the clamping frame 42 between the two fastening strips 25, and further pressing the position between the fastening strips 25 to enhance the sealing effect. During the rotation of the clamping frame 42, its edge will squeeze the rubber block 43. After the rubber block 43 is deformed under force, it will be stuck at one end between the two fastening strips 25. The elasticity and friction of the rubber form a mechanical limit, effectively preventing the clamping frame 42 from loosening and ensuring that the sealing structure remains stable and reliable during the testing process.

Clearly, many modifications and variations can be made based on the content of this specification.
