Description

Technical Field

[0001] This invention relates to the field of hydrogen cannon experimental technology, and in particular to a diaphragm disassembly device. Background Technology

[0002] To address the issue of increasing projectile velocity, a two-stage hydrogen gun has been developed. Using a two-stage hydrogen gun as a loading device for high-pressure material property parameter research experiments is currently a widely used high-speed and ultra-high-speed loading system both domestically and internationally. The diaphragm is a key component in the two-stage hydrogen gun experiment, with only a few dimensional checks on its fit with the launch tube. After the large bolt and sleeve are tightened, a high-mass piston compresses the pre-filled light gas in the pump tube at a relatively low speed, causing its pressure and temperature to rise continuously. When the pressure reaches a predetermined value, the diaphragm in the launch tube ruptures.

[0003] After the loading experiment, the gun body was restored, the launch tube was cleaned and restored, and the diaphragm, which had ruptured, was tightly pressed and adhered to the launch tube inlet. Removing the diaphragm was still quite difficult. Currently, the methods used are either scraping with a flat chisel or threading a thin wire through the launch tube inlet to the launch tube outlet, binding a tool slightly smaller than the launch tube diameter, and pulling it from the launch tube outlet to the diaphragm position at the launch tube inlet, then pulling out the diaphragm by tightening the bolts. Existing methods for removing the diaphragm, such as scraping with a flat chisel, easily damage the launch tube inlet and can significantly affect the projectile's firing status. Using a tool requires waiting for the target chamber to open, which is cumbersome, labor-intensive, and inefficient, and may scratch the inner chamber of the launch tube, affecting its performance and quality. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a membrane removal device that enables safe, convenient, and efficient membrane removal.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a diaphragm disassembly device, comprising: An assembly rod, one end of which is detachably provided with a spring clip; The elastic clip includes an integrally connected connecting part and an expanding part. When the assembly rod is connected to the elastic clip, the expanding part can be expanded. An inner liner block, which is disposed on the expansion portion; An abutment plate is disposed at the end of the assembly rod away from the spring clip; An impact block, which is slidably mounted on the assembly rod, is capable of sliding towards the side of the abutment plate and impacting it.

[0006] Furthermore, the assembly rod includes a rod body and a threaded rod disposed at one end of the rod body, the connecting part is screwed into the threaded rod, and the threaded rod can also extend into the expansion part and expand it.

[0007] Furthermore, a first mounting groove is provided on the rod body, and at least three support components are inserted into the first mounting groove. The support components can align the rod with the axis of the gun barrel when the assembled rod is located inside the gun barrel. A limiting component is rotatably provided on the rod body. The limiting component can rotate to a locked or unlocked position by rotating in one direction or in another direction. When the limiting component is rotated to the locked or unlocked position, it can limit or release the support component inserted into the first mounting slot.

[0008] Furthermore, the support assembly includes an insert plate inserted into the first mounting slot, and a ball bearing is provided on the side of the insert plate away from the first mounting slot.

[0009] Furthermore, a telescopic rod is provided on the side of the insert plate away from the first mounting groove, and a spring is provided inside the telescopic rod that contacts the telescopic end of the telescopic rod. The ball is rotatably disposed on the telescopic end of the telescopic rod.

[0010] Furthermore, the limiting component includes an adjusting ring rotatably mounted on the rod body, a limiting bracket is provided on the adjusting ring, and a slot is provided inside the insert plate. When the limiting component is rotated to the locked position, the limiting bracket is inserted into the slot.

[0011] Furthermore, the limiting frame is provided with a magnet, and when the limiting frame is inserted into the slot, the magnet can be magnetically attracted and positioned with the insert plate.

[0012] Furthermore, the impact block is provided with an operating component, which includes a second mounting groove formed on the impact block, an assembly frame detachably disposed in the second mounting groove, and a handle vertically disposed on the assembly frame.

[0013] Furthermore, a soft padding layer is provided on the top of the impact block.

[0014] The beneficial effects of this invention are reflected in: In this invention, the operator inserts the spring clip into the barrel and passes it through the rupture of the diaphragm. At this time, the inner liner block also moves synchronously to the other side of the diaphragm. After processing, the assembly rod and the spring clip are assembled. After assembly, the expansion part is opened by the assembly rod, thereby causing the inner liner blocks on it to expand synchronously. In this state, the relative distance between the inner liner blocks is increased, making it difficult for them to easily leave the other side of the diaphragm. Finally, the operator quickly pulls the impact block towards the side close to the contact plate, so that the instantaneous impact force generated when the impact block slides hits the contact plate, thereby driving the assembly rod to move. In this state, the spring clip and the inner liner block move synchronously and bring out the ruptured diaphragm at the inlet of the launch tube, thus completing the diaphragm removal operation. This device is safe and convenient to operate, and can efficiently disassemble and remove the diaphragm for practical use. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-5The present invention discloses a diaphragm disassembly device, including an assembly rod 1. The assembly rod 1 is cylindrical in shape, and one end of the assembly rod 1 is detachably provided with an elastic clip 2. The elastic clip 2 includes an integrally connected connecting part 21 and an expansion part 22. When the assembly rod 1 is connected to the elastic clip 2, the expansion part 22 can be expanded.

[0019] In one embodiment, the expansion support 22 is provided with an inner liner block 3, the inner liner block 3 is arc-shaped and there are no less than three of them. The end of the assembly rod 1 away from the elastic clip 2 is provided with an abutment plate 4, and an impact block 5 is slidably provided on the assembly rod 1. The impact block 5 can slide towards the side close to the abutment plate 4 and impact it.

[0020] In practice, the operator inserts the elastic clip 2 into the barrel and passes it through the rupture of the diaphragm. At this time, the inner liner block 3 also moves synchronously to the other side of the diaphragm. After processing, the assembly rod 1 and the elastic clip 2 are assembled. After assembly, the expansion part 22 is opened by the assembly rod 1, so that each inner liner block 3 on it moves synchronously and expands. In this state, the relative distance between each inner liner block 3 is increased, and it is difficult for them to easily leave the other side of the diaphragm. Finally, the operator quickly pulls the impact block 5 towards the side close to the contact plate 4, so that the instantaneous impact force generated when the impact block 5 slides hits the contact plate 4, thereby driving the assembly rod 1 to move. In this state, the elastic clip 2 and the inner liner block 3 move synchronously and bring out the ruptured diaphragm at the inlet of the launch tube, thus completing the diaphragm removal operation. This device is easy to operate and can efficiently disassemble and remove the diaphragm for practical use.

[0021] In one embodiment, the assembly rod 1 includes a rod body 11 and a threaded rod 12 installed at one end of the rod body 11, and the connecting part 21 is screwed into the threaded rod 12. In practice, the expansion section 22 consists of multiple arc-shaped and elastic sheets, with each inner liner 3 installed on the corresponding sheet. The threaded rod 12 can be screwed into the connecting section 21 by rotation. As the screwing continues, the threaded rod 12 can also extend into the expansion section 22 and spread each sheet apart. The displacement of the threaded rod 12 will also cause the connecting section 21 to move together, so as to facilitate film removal.

[0022] In the second embodiment of the present invention, a first mounting groove 13 is provided on the rod 11, and at least three support components 6 are inserted into the first mounting groove 13, while a limit component 7 is rotatably mounted on the rod 11.

[0023] In practice, the support component 6 can align the assembly rod 1 with the axis of the transmitter tube when the assembly rod 1 is inside the transmitter tube. Therefore, when removing the membrane, the support component 6 can ensure that the assembly rod 1 will not contact the inner wall of the transmitter tube, thereby effectively preventing damage to the inner wall of the transmitter tube when removing the membrane. In addition, the limiting component 7 mentioned above can rotate in one direction or in another direction to a locked or unlocked position. When the limiting component 7 rotates to the locked or unlocked position, it can limit or release the limiting of the support component 6 inserted into the first mounting groove 13, so as to facilitate actual installation and disassembly.

[0024] In one embodiment, the support component 6 includes an insert plate 63 inserted into the first mounting groove 13, and a ball bearing 62 is provided on the side of the insert plate 63 away from the first mounting groove 13.

[0025] With this design, when the rod 11 moves inside the launch tube, the rolling ball 62 contacts and rolls against the inner wall of the launch tube, thus ensuring smooth movement and preventing scratches to the inner wall of the launch tube. In one embodiment, a telescopic rod 61 is installed on the side of the insert plate 63 away from the first mounting groove 13. A spring (not shown in the figure) is provided inside the telescopic rod 61 to contact the telescopic end of the telescopic rod 61. A ball 62 is rotatably disposed at the telescopic end of the telescopic rod 61.

[0026] In practice, the telescopic rod 61 and the spring work together to enable the support assembly 6 to adapt to the film taking operation of various sizes of launch tubes.

[0027] In one embodiment, the limiting component 7 includes an adjusting ring 71 rotatably mounted on the rod 11, and a number of limiting frames 72 corresponding to the number of insert plates 63 are mounted on the adjusting ring 71. The insert plates 63 have slots 73 inside.

[0028] In practice, when the corresponding adjusting ring 71 of the limiting component 7 rotates to the locked position, the limiting frame 72 will also rotate synchronously and be inserted into the slot 73, so that each insert plate 63 is stably installed in the first mounting slot 13. When the adjusting ring 71 is rotated in the opposite direction to the unlocked position, the limiting frame 72 will rotate synchronously and leave the slot 73, thus facilitating the assembly and removal of the support component 6.

[0029] In one embodiment, a magnet (not shown) is installed on the limiting frame 72. When the limiting frame 72 is inserted into the slot 73, the magnet can be magnetically positioned with the insert plate 63.

[0030] In practice, when the limiting frame 72 rotates synchronously and is inserted into the slot 73, the magnetic attraction positioning of the magnet and the insertion plate 63 can ensure better stability when the insertion plate 63 is in a fixed state, thereby ensuring good safety during the film removal operation.

[0031] In one embodiment, an operating component 8 is provided on the impact block 5. The operating component 8 includes a second mounting groove 81 formed on the impact block 5. An assembly frame 82 is detachably mounted in the second mounting groove 81. A handle 83 is vertically provided on the assembly frame 82.

[0032] In practice, the assembly frame 82 is fixed in the second mounting slot 81 by bolts. The worker can move and adjust the impact block 5 by holding the handle 83. This design prevents the worker's hand from directly contacting the impact block 5, thereby preventing the impact block 5 from having an adverse effect on the worker's safety when it hits the abutment plate 4.

[0033] In one embodiment, an installed pad 9 is provided on the top of the impact block 5.

[0034] In practice, the pad 9 can be a sponge layer. This design can further improve the operational safety at this point without significantly affecting the impact of the impact block 5 against the contact plate 4, thus facilitating actual use.

[0035] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
