Description

Technical Field

[0001] The present invention relates to the field of weapon accessories, and in particular to a clamping mechanism and a clamping and cutting platform. Background Art

[0002] With the advancement of science and technology and the rapid development of the weapons industry, the development of new ammunition has gradually accelerated, and the speed of ammunition replacement has also accelerated. This has resulted in a large amount of obsolete ammunition. Its safety performance has been reduced, and its continued use is dangerous. At the same time, the storage of obsolete ammunition also poses a great safety hazard to ammunition depots, and must be forcibly dismantled as soon as possible.

[0003] As one of the types of ammunition that urgently needs to be scrapped and dismantled, rocket launcher ammunition has many characteristics such as complex structure, tight installation, wide variety and low stability. Currently, all of them are dismantled manually, and the dismantling process requires a large number of clamping, screwing and other tooling and tools.

[0004] Since thread sealant is applied to the threads of rocket launcher bullets during manufacturing to ensure a secure threaded connection, a large torque is required to loosen them. Currently, a vise fixed to a workbench is often used to clamp the warhead, and a pipe wrench or special tool is used to screw the rocket head to loosen the threads. The existing technical solutions have too small a contact surface, unstable clamping, and are very likely to cause warhead deformation. The deformation of the warhead is further aggravated during screwing and separation, and safety hazards increase significantly. Summary of the Invention

[0037] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0038] Example 1

[0039] The first embodiment of the present invention provides a clamping mechanism, such as Figure 1 As shown, the clamping mechanism includes a disassembly table 3, a locking assembly, a clamping assembly and a limiting sleeve 14;

[0040] The clamping assembly is hinged on the disassembly table 3, and the limiting sleeve 14 is fixed on the side of the disassembly table 3 opposite to the clamping assembly and is connected to the clamping assembly;

[0041] The locking assembly is hinged to the clamping assembly;

[0042] The locking assembly is loosened or tightened to open or lock the clamping assembly.

[0043] In this embodiment, if Figure 1 As shown, the clamping mechanism includes a table pressure plate 1, a disassembly table 3, a locking assembly, a clamping assembly and a limit sleeve 14. The table pressure plate 1 is arranged on the disassembly table 3, and the two can be fixed by fixing bolts 2. The clamping assembly is hinged on the disassembly table 3, and the limit sleeve 14 is fixed on the other side of the disassembly table 3 opposite to the clamping assembly, and is connected with the clamping assembly. When clamping ammunition, the limit sleeve 14 can effectively provide a larger contact surface, thereby improving the stability of clamping.

[0044] In summary, the embodiment of the present invention achieves the clamping of ammunition by cooperating with the clamping assembly and the limiting sleeve 14. At the same time, the provision of the limiting sleeve 14 can increase the contact area between the clamping mechanism and the ammunition, thereby solving the problem of unstable clamping in the prior art.

[0045] Optionally, in an optional embodiment of the present invention, the clamping assembly includes a jaw 8 , and one end of the jaw 8 is mounted on the disassembly table 3 via a first jaw hinge shaft 10 .

[0046] like Figure 1 As shown, in this embodiment, the jaws 8 include two jaw blocks, wherein one end of the two jaw blocks is respectively mounted on the disassembly table 3 through a first jaw hinge shaft 10 .

[0047] Optionally, the locking assembly includes a second jaw hinge shaft 4, a jaw hinge head 5 and a locking screw 6;

[0048] The second jaw hinge shaft 4 is used to hinge the other end of the jaw 8 to the jaw hinge head 5;

[0049] The other end of the jaw 8 is also arranged in the jaw hinge 5;

[0050] The locking screw 6 is loosened and tightened to enable the other end of the jaw 8 to open and close within the range of the jaw hinge 5 .

[0051] Specifically in this embodiment, the locking assembly includes a second jaw hinge shaft 4, a jaw hinge head 5 and a locking screw 6, wherein the second jaw hinge shaft 4 is used to hinge the other end of the jaw 8 with the jaw hinge head 5, as shown in FIG. Figure 1 As shown, the second jaw hinge shaft 4 is hinged to the other end of one of the jaw blocks of the jaw 8, and the other end of the other jaw block is arranged in the jaw hinge joint 5. By loosening and tightening the locking screw 6, the other end of the other jaw block can be opened and closed within the range of the jaw hinge joint 5, thereby achieving clamping of different spring types.

[0052] Optionally, the locking assembly further includes a locking rod 7;

[0053] One end of the locking rod 7 is arranged on the locking screw 6, and the other end of the locking rod 7 is suspended in the air;

[0054] The locking rod 7 is rotated to loosen or tighten the locking screw 6 .

[0055] Further, if Figure 1 As shown, the locking rod 7 can increase the speed of loosening and tightening, thereby improving the use efficiency of the clamping device.

[0056] Optionally, the clamping assembly further includes a compression spring 13, which is arranged between two opening and closing parts at one end of the jaw 8;

[0057] The compression spring 13 is used to provide an unlocking elastic force when the locking assembly unlocks the jaws 8 .

[0058] Further, if Figure 1 As shown, based on the above embodiment, in this embodiment, a compression spring 13 is arranged between one end of the two jaw blocks, which can provide unlocking elastic force through the compression spring 13 during the process of loosening the locking screw 6, thereby increasing the unlocking speed. In an optional embodiment, the compression spring 13 is fixed by a compression spring support plate 12, and the compression spring support plate 12 can be fixed to the disassembly table 3 by a compression spring support plate screw 11.

[0059] Optionally, the clamping mechanism further includes a clamping tool;

[0060] The limiting sleeve 14 is used to cooperate with the clamping fixtures of different specifications to achieve the clamping of multiple spring types.

[0061] Optionally, the limiting sleeve 14 is a cylindrical structure, and the jaws 8 are an arc-shaped structure.

[0062] like Figure 2 As shown, in this embodiment, the limiting sleeve 14 can be set to a cylindrical shape, wherein the limiting sleeve 14 corresponds to the hole position of the jaws 8, and at the same time, a hole is opened on the corresponding position of the disassembly table 3, so that the ammunition to be clamped can pass from the limiting sleeve 14 to the outside of the jaws 8. Therefore, the limiting sleeve 14 is used to cooperate with clamping tooling of different specifications to complete the clamping of multiple types of ammunition. In this embodiment, the ammunition to be clamped can be a rod-shaped ammunition similar to a rocket launcher ammunition. Of course, inspired by the scheme of this embodiment, ammunition of other shapes only needs to replace the limiting sleeve and jaws of matching shapes.

[0063] Optionally, the clamping tool comprises: matching jaws and corresponding positioning sleeves;

[0064] When the clamping mechanism is clamping, the matching jaws are used to be installed on the jaws 8, and the corresponding positioning sleeves are installed in the limiting sleeves 14 to complete the clamping.

[0065] In this embodiment, a set of clamping fixtures can be provided for each type of ammunition. Taking the 120mm ammunition type as an example, the clamping mechanism of the present invention is used as follows: the 120mm positioning sleeve 15 is placed in the limiting sleeve 14, the locking rod 7 is rotated to unscrew the locking screw 6, the jaw hinge 5 is pulled out, the jaws 8 are opened under the action of the compression spring 13, and the 120mm bazooka ammunition is vertically inserted into the limiting sleeve 14. The jaws 8 are manually closed, the jaw hinge 5 is pushed up, and the locking screw 6 is tightened. At this point, the jaws 8 and the 120mm positioning sleeve 15 jointly clamp and lock the ammunition head. The ammunition head can then be removed by screwing with a tool, and the matching jaws and positioning sleeves of other ammunition types can be replaced to clamp other ammunition types.

[0066] Optionally, the jaw 8 and the upper matching jaw are further provided with positioning holes;

[0067] The positioning holes are used to achieve the installation and positioning of the matching jaws and the jaws 8.

[0068] In another embodiment of the present invention, the size of the jaws 8 can be directly set to a size that matches a larger bullet. For example, in this embodiment, three types of rocket launcher bullets, 80 / 93 / 120, are used as examples. Other similar ammunition can also be clamped by this solution. The caliber size of the jaws 8 is set to match the 120 rocket launcher bullet type, that is, the jaws 8 are equivalent to the 120 matching jaws. When clamping the 120 rocket launcher bullet, the matching jaws corresponding to the 120 rocket launcher bullet can be omitted. When clamping the 80 / 93 bullet type, the corresponding matching jaws and positioning sleeves can be replaced.

[0069] For example, Figure 3 、 Figure 4 As shown, place the 80 positioning sleeve 17 in the limiting sleeve 14, place the 80 matching jaws 16 on the jaws and insert the jaw positioning pin 9 into the positioning hole to fix it, so that it can be used to clamp the 80 rocket launcher bullet.

[0070] Place the 93 positioning sleeve 19 in the 14 limiting sleeve, place the 93 matching jaws 18 on the jaws 8 and insert the jaw positioning pin 9 into the positioning hole to fix it, so that it can be used to clamp the 93 rocket launcher bullet, thereby improving the use efficiency of the clamping mechanism.

[0071] Optionally, the inner sides of the jaws 8 and the matching jaws are provided with tooth-shaped anti-slip structures.

[0072] Specifically, such as Figure 5As shown in the figure, when clamping the bullet, the arc of matching dimensions applies uniform radial pressure to the bullet, and the teeth on the inner side of the arc effectively increase friction, ultimately achieving effective clamping of the bullet while avoiding deformation of the bullet.

[0073] In another embodiment, see Figure 4 As shown, each type of matching jaws has two jaw blocks that are smaller than a semicircle, the arc diameter of which matches the outer diameter of the adapted bullet, and fine teeth are processed on the inside of the arc.

[0074] Furthermore, taking the three types of bullets 80 / 93 / 120 as an example, in order to increase the clamping friction of the rocket launcher bullet, the 120 rocket launcher bullet is directly clamped by the jaws 8, so a tooth-shaped anti-slip structure is provided on the inner side of the jaws 8. At the same time, 80 / 93 is clamped by the 80 matching jaws and the 93 matching jaws. Therefore, in another embodiment, a tooth-shaped anti-slip structure can also be provided on the 80 matching jaws and the 93 matching jaws.

[0075] In summary, the clamping mechanism of the present invention has the following advantages:

[0076] 1) The mechanism can be disassembled and moved;

[0077] 2) Ability to achieve multi-elastic adaptive clamping;

[0078] 3) The upper jaw of the mechanism is clamped and the lower jaw is positioned, which has the characteristic of stable projectile after clamping;

[0079] 4) It has a compression spring that automatically opens the jaws after it comes out of the way;

[0080] 5) The locking rod slides inside the locking screw and can freely adjust the length, can adapt to small spaces, and can provide a large torque.

[0083] Specifically, this embodiment proposes an ammunition clamping platform, on which the aforementioned clamping mechanism is provided. The clamping platform can further perform subsequent processing on the ammunition after the clamping mechanism completes the clamping of the ammunition, such as cutting processing. By providing the aforementioned clamping mechanism, the stability and processing efficiency of the clamping platform can be further improved.
