When the unit-shaped explosive charge is connected to the unit-shaped explosive charge in front, if the magnetic force is not adjusted, the unit-shaped explosive charge will be difficult to move due to the large magnetic force, making it difficult to dock with the unit-shaped explosive charge in front. This will affect efficiency and increase the risk of detonation and damage. Utility Model Content

Detailed Implementation

[0015] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0016] like Figure 1-8 As shown, a magnetic force adjustment device for ammunition loading includes a support 1. The support 1 is equipped with a magnetic chuck 2 for moving a shaped charge 5 towards a target adsorption surface and a limiting assembly 3 for quickly releasing the magnetic chuck 2. The limiting assembly 3 includes a supporting rotating rod 31, a connecting rod 32 for connecting the shaped charge 5, and a limiting member 6 for fixing the height of the supporting rotating rod 31. One end of the connecting rod 32 is connected to the shaped charge 5, and the other end passes through the support 1 and is fixedly connected to a limiting block 321. The limiting member 6 is connected to the support 1, and the supporting rotating rod 31 is rotatably connected to the support 1. The supporting rotating rod 31 is provided with a accommodating element for the limiting member. The limiting groove 3111 of the 6 is a straight groove with a depth greater than the cross-sectional radius of the limiting member 6. When the limiting member 6 is inserted into the limiting groove 3111, the bracket 1 and the magnetic chuck 2 are fixed, and the magnetic chuck 2 maintains a distance from the target adsorption surface, thereby reducing the magnetic force and facilitating the movement and docking of the shaped charge 5. The working surface of the magnetic chuck 2 is opposite to the target adsorption surface. A hydraulic buffer 4 is installed on the magnetic chuck 2 to lift the magnetic chuck 2. The output end of the hydraulic buffer 4 can be operated to move to the working surface of the magnetic chuck 2. When the magnetic chuck 2 is in contact with the target adsorption surface, the hydraulic buffer 4 provides damping to slow down the adsorption speed and ensure stable adsorption.

[0017] Specifically, there are two magnetic chucks 2 arranged symmetrically and distributed on both sides of the energy-concentrating charge 5. Each magnetic chuck 2 is installed through a fixing plate 12 on the bracket 1 to improve adsorption stability.

[0018] Specifically, the bracket 1 includes a top plate 11, and both ends of the top plate 11 are fixedly connected to a fixing plate 12 for connecting the magnetic chuck 2. The fixing plate 12 has an arc-shaped structure, providing enough space to accommodate the magnetic chuck 2 and the hydraulic buffer 4, thereby enhancing the overall rigidity.

[0019] Specifically, the fixing plate 12 is L-shaped, and the bottom of the fixing plate 12 is provided with a magnetic mounting hole for mounting the magnetic chuck 2. The magnetic chuck 2 is fixed on the fixing plate 12 through the magnetic mounting hole and can move with the bracket 1 to realize magnetic force adjustment.

[0020] Specifically, the magnetic chuck 2 has a clearance hole in the center, and the output end of the hydraulic buffer 4 passes through the clearance hole. When it is necessary to remove the shaped charge 5, the output end of the hydraulic buffer 4 is operated to lift the magnetic chuck 2, so that the magnetic chuck 2 is separated from the target adsorption surface, reducing the magnetic force and facilitating disassembly.

[0021] Specifically, the top plate 11 is provided with an adjustment hole 111, and the shaped charge 5 is provided with a corresponding positioning groove. The supporting rotating rod 31 includes a handle and a rod. After the working surface and the target adsorption surface approach each other along the first axis, the rod can abut in the positioning groove. The rod of the supporting rotating rod 31 is rotatably connected to the adjustment hole 111 and slidably connected to the adjustment hole 111 along the first axis. The rod of the supporting rotating rod 31 is provided with an annular groove 3112. The depth of the annular groove 3112 is less than the cross-sectional radius of the limiting member 6 to prevent the supporting rotating rod 31 from falling off the bracket 1, while allowing the limiting member 6 to be released after rotation.

[0022] Specifically, the top plate 11 is provided with a connection hole 112, and the connecting rod 32 is slidably connected to the connection hole 112. The connection hole 112 is a stepped hole, which is used to pass through the connecting rod 32 and to constrain the bracket 1 to prevent it from detaching from the shaped charge 5, thus ensuring a safe connection.

[0023] Specifically, the adjustment hole 111 is located in the middle of the top plate 11, and there are two connecting holes 112 symmetrically arranged about the adjustment hole 111 to ensure that the bracket 1 is balanced, the magnetic chuck 2 is evenly stressed, and the reliability of the device is improved.

[0024] Specifically, the shaped charge 5 is provided with a corresponding assembly screw hole, the connecting rod 32 and the limiting block 321 are integrally formed, the limiting block 321 is provided with a wrench hole 3211, the connecting rod 32 is threaded to the assembly screw hole, the tightness of the connecting rod 32 can be adjusted through the wrench hole 3211 to ensure that the shaped charge 5 is reliably connected to the bracket 1, and to facilitate installation and disassembly.

[0025] Specifically, the limiting component 6 is made of steel wire, and the steel wire is bow-shaped. The bracket 1 is provided with an insertion hole 113 and an L-shaped hole 114 for installing the steel wire. The two ends of the steel wire are bent. First, one end is inserted into the insertion hole 113, and then the other end is inserted into the L-shaped hole 114 by taking advantage of the elasticity of the steel wire and the large space of the L-shaped hole 114. The straight part in the middle is stuck in the limiting groove 3111 of the supporting rotating rod 31 to realize the limiting function. The operation is simple and can quickly release the magnetic force.

[0026] The device operates as follows: In the initial state, the limiting member 6 is locked in the limiting groove 3111 of the supporting rotating rod 31, fixing the bracket 1 and the magnetic chuck 2. The working surface of the magnetic chuck 2 maintains a distance of about 10mm from the target adsorption surface, and the magnetic force is relatively small. At this time, it can move freely and dock with the shaped charge 5. After rotating the supporting rotating rod 31 by several tens of degrees, the limiting member 6 slides out of the limiting groove 3111. Under the action of magnetic force, the bracket 1 drives the magnetic chuck 2 to move towards the target adsorption surface. The hydraulic buffer 4 provides damping, so that the magnetic chuck 2 smoothly fits the target adsorption surface and reaches the maximum magnetic force. In special cases, when it is necessary to remove the shaped charge 5, the end of the hydraulic buffer 4 can be operated with a tool to make its output end lift the magnetic chuck 2, forcibly separating it to reduce the magnetic force and facilitate disassembly.

[0027] The hydraulic buffer 4 is specifically an oil pressure buffer, which is filled with hydraulic oil and has a precision throttling orifice. When the magnetic chuck 2 quickly approaches the target adsorption surface, the piston rod of the oil pressure buffer is compressed, which pushes the hydraulic oil through the throttling orifice to form a damping force, effectively absorbing the impact energy and avoiding rigid collision between the magnetic chuck 2 and the side of the ship, thus ensuring the stability of the adsorption process and the service life of the device.

[0028] The bracket 1 adopts a symmetrical bow-shaped structure. The top plate 11 and the L-shaped fixing plates 12 on both sides form a stable frame, which can evenly distribute the adsorption force generated by the magnetic chuck 2 and prevent tilting or failure caused by uneven force. The magnetic chuck 2 is made of permanent magnet material. The magnetic force can be infinitely varied by adjusting the distance from the target adsorption surface. The structure is simple and reliable and can work without external energy.
