Description

Technical Field

[0001] The invention belongs to the technical field of pyrotechnic product decomposition, and in particular relates to an ammunition decomposition progress indicating system, ammunition decomposition equipment and a decomposition method. Background Art

[0002] When ammunition reaches the end of its storage life, it is usually necessary to replace short-life parts to extend the ammunition's storage life in order to avoid wasting ammunition. Normally, ammunition parts need to be disassembled to replace them. During the assembly of ammunition, parts connected by threads are often coated with thread lockers and pre-tightened to prevent them from loosening during transportation, which makes ammunition disassembly very difficult. Moreover, ammunition disassembly is a reverse operation, and due to the structural design of the ammunition, it may be necessary to partially release the fuse, thus increasing the risk of ammunition disassembly.

[0003] For safety reasons, ammunition disassembly adopts a human-machine isolation method. The disassembly equipment is placed in an explosion-proof room. All equipment and tools used should be explosion-proof, which improves the safety of the ammunition disassembly process to a certain extent.

[0004] However, in general, ammunition disassembly is limited by the structure of the ammunition itself and the disassembly equipment. During disassembly, the ammunition is usually completely sunk in the equipment, and the disassembled parts (such as fuses, pressure screws, etc.) are often installed inside the ammunition shell. Therefore, it is impossible to directly observe the disassembled parts and their status during the disassembly process and whether the disassembly has been completed. It can only be indirectly controlled by the time the equipment is running. In the end, the operator still needs to enter the explosion-proof room to take out the disassembly tooling and then observe whether the disassembly is completed. In other words, the existing ammunition disassembly equipment cannot timely and accurately observe the process and results of disassembly of parts. On the other hand, if there are abnormal conditions such as slipping of the projectile body, it cannot be discovered in time, which may cause friction heat accumulation in the ammunition, causing explosion and combustion accidents, bringing huge risks to ammunition disassembly.

[0030] Example: See also Figure 1~Figure 5 The ammunition disassembly progress indication system in the preferred embodiment of the present invention includes a progress indication component 1 that can be matched and set on the ammunition disassembly device. By setting it outside the ammunition disassembly device and matching and connecting with the ammunition disassembly component 3, the progress of the ammunition disassembly component 3 disassembling the second part 502 to be disassembled on the ammunition 5 can be displayed in real time by the progress indication component 1, so that the operating personnel can accurately complete the real-time grasp of the ammunition disassembly progress outside the explosion-proof room.

[0031] Specifically, the progress indicating assembly 1 in the preferred embodiment includes an indicating rod 101 , a pointer 102 and a pointer frame 103 which are arranged in combination.

[0032] The indicator rod 101 is a rod-shaped structure arranged vertically, and its bottom is a connection end 1011 that can be connected and matched with the wrench body 301 in the ammunition disassembly assembly 3. Through the connection between the connection end 1011 and the wrench body 301, the indicator rod 101 can follow the wrench body 301 in the process of rotating and lifting. At the same time, on the outer periphery of the indicator rod 101, a plurality of scales are sequentially arranged along the axial direction. Through the indication of the pointer 102, the position of the indicator rod 101 relative to the pointer 102 can be quickly read, thereby completing the real-time judgment of the position of the wrench body 301, and then knowing the disassembly progress of the second part 502 to be disassembled on the ammunition 5.

[0033] In more detail, in the preferred embodiment, the scale on the indicator rod 101 is preferably realized by providing a plurality of grooves spaced axially on the outer circumference of the indicator rod 101. In actual configuration, the groove width and / or adjacent intervals of each groove may be the same, or may be different as required.

[0034] For example, in Figure 2 In the preferred embodiment shown, two scales are formed in the length direction of the indicator rod 101, namely, a first scale section close to the connection end 1011 and a second scale section far from the connection end 1011. In the first scale section, a plurality of first grooves 1012 with equal widths are spaced apart along the axial direction of the rod body, and the interval between two adjacent first grooves 1012 is preferably equal to the width of the first groove 1012. Correspondingly, a plurality of second grooves 1013 with equal widths are spaced apart along the axial direction of the rod body in the second scale section, and the interval between two adjacent second grooves 1013 is preferably equal to the width of the second groove 1013 along the axial direction.

[0035] More specifically, the widths of the first groove 1012 and the second groove 1013 in the preferred embodiment are preferably different. For example, in the preferred embodiment, the width of the first groove 1012 is preferably 1.5 to 3 times, and more preferably 2 times, of the second groove 1013. With the above arrangement of the grooves on the two scale segments, the indicator rod 101 can satisfy the disassembly and assembly progress indication of different ammunition parts.

[0036] It can be understood that, according to different actual setting requirements, two, for example, three or four scale segments of different scale sizes can be arranged.

[0037] At the same time, for the opening of each groove, it is preferred to apply a corresponding color in each groove to form a scale with different display colors. In actual settings, it is preferred to set the color scales in two adjacent grooves to be different to improve the accuracy of recognition. In addition, it is further preferred to set a corresponding scale number on the rod between the two grooves to further improve the accuracy of scale recognition.

[0038] Furthermore, the pointer 102 in the preferred embodiment is preferably in the shape of a long rod, one end of which is an indicating end for aligning the scale, and the other end is a mounting end for connecting the pointer frame 103. The pointer frame 103 in the preferred embodiment includes a base, a vertical rod and a horizontal rod. The base is used to be fixed on the workbench 402 of the device, the bottom end of the vertical rod is connected to the base, the top end is connected to one end of the horizontally arranged horizontal rod, and the other end of the horizontal rod is connected to the mounting end of the pointer 102, as shown in FIG. Figure 2 as shown in .

[0039] In a preferred embodiment, the connection between the crossbar and the vertical bar is preferably a detachable connection, and a plurality of mounting positions are arranged on the vertical bar at intervals along the axial direction, so that the crossbar can be installed at different positions on the vertical bar as needed. Then, the scale segment corresponding to the pointer 102 is changed to meet the disassembly and assembly requirements of different parts.

[0040] Furthermore, since the intervals between the scales on the indicator rod 101 are often small, and the operator and the ammunition disassembly equipment are in different spaces, in a preferred embodiment, an observation mechanism 104 is provided for identifying the scales on the indicator rod 101, by which the scales to which the pointer 102 is aligned can be quickly and accurately identified and read.

[0041] In a preferred embodiment, the observation mechanism 104 preferably includes a magnifying glass 1041, a camera 1042 and a display screen 1043, wherein the magnifying glass 1041 is arranged between the camera 1042 and the indicator rod 101, and the camera 1042 is electrically connected to the display screen 1043. Through the magnified field of view of the magnifying glass 1041, the camera 1042 can accurately capture the scale indicated by the pointer 102 and display it on the display screen 1043.

[0042] During actual setting, the display screen 1043 is preferably set outside the explosion-proof room, and the operating personnel can accurately complete the disassembly and assembly progress through the display screen 1043.

[0043] In addition, in actual configuration, the connecting end 1011 of the indicator rod 101 may be directly connected to the wrench body 301, or may be indirectly connected via a separate component. Figure 4 In the preferred embodiment shown in FIG. 1 , the indicator rod 101 is connected to the wrench body 301 via a counterweight 105. Figure 5 As shown in , it is a cylindrical structure as a whole, and the protruding end surfaces of the two axial ends are respectively provided with protrusions, forming a connecting portion connecting the end of the indicator rod 101 and a matching portion matching the middle through hole of the wrench body 301.

[0044] In more detail, in a preferred embodiment, a threaded hole is axially provided on the connection portion at the top of the counterweight 105, so that the connection end 1011 of the indicator rod 101 can be threadedly connected to the counterweight 105. Since the counterweight 105 itself has a certain self-weight, when the matching portion is embedded in the through hole in the middle of the wrench body 301, the counterweight 105 can be reliably placed on the wrench body 301 based on its own weight, thereby ensuring the reliability of the relative position of the indicator rod 101 and the wrench body 301 after they are connected to each other, and vertically pressing the wrench body 301 and the disassembly seat 302 on the corresponding first part to be disassembled 503, avoiding the separation between the disassembly seat 302 and the first part to be disassembled 503 during the disassembly process, and also avoiding the shaking or displacement of the indicator rod 101 during the operation.

[0045] In a preferred embodiment, through the combined arrangement of the indicator rod 101, the pointer 102, the pointer rack 103, the observation mechanism 104 and the counterweight block 105, the real-time display of the disassembly progress of the second part 502 to be disassembled on the ammunition 5 can be achieved, thereby ensuring the reliability and safety of the disassembly of the corresponding parts of the ammunition 5.

[0046] As a further development of the present invention, an ammunition disassembly device is also provided in a preferred embodiment, which includes an equipment body 4, a cavity for accommodating ammunition to be disassembled is formed inside the equipment body 4, and an ammunition clamping assembly 2 and an ammunition disassembly assembly 3 are arranged in the cavity. The ammunition clamping assembly 2 can be used to fix the ammunition 5 in the equipment body 4, and then the combined setting and control of the ammunition disassembly assembly 3 can be used to realize the disassembly of the corresponding second part 502 to be disassembled on the ammunition 5.

[0047] Specifically, the device body 4 in the preferred embodiment includes a workbench 402 and a frame 401 supported below the workbench 402, and the aforementioned accommodating cavity is formed inside the frame 401. At the same time, an ammunition placement hole is opened on the workbench 402 corresponding to the location where the ammunition clamping assembly 2 is set, for placing the ammunition 5 in the vertical direction and for passing the counterweight 105.

[0048] In more detail, the ammunition clamping assembly 2 in the preferred embodiment includes a support member 202 located below the ammunition placement hole, and a clamping member 201 is provided on the circumferential side above the support member 202, so that the ammunition 5 can be supported at its bottom on the support member 202, and the clamping member 201 can reliably clamp the outer periphery of the body 501 of the ammunition 5.

[0049] In actual configuration, the clamping member 201 is preferably a three-jaw chuck, which can be pneumatically or hydraulically controlled to achieve tightness control, thereby reliably clamping or releasing the ammunition 5.

[0050] In addition, in order to meet the requirements of the ammunition clamping assembly 2 for clamping different types of ammunition 5, a lifting mechanism 203 is preferably provided at the bottom of the support 202, such as a hydraulic cylinder in the preferred embodiment, which can adjust the vertical position of the support 202. At the same time, in order to quickly position the ammunition 5 on the support 202, a conical blind hole is preferably opened at the top of the support 202 to match the conical shape of the end of the projectile 501.

[0051] Further, the ammunition decomposition assembly 3 in the preferred embodiment is as follows Figure 6 As shown in the figure, it includes a reduction box 306, a driving motor 305 and a driving gear 304 which are arranged in the cavity of the frame 401 and assembled and connected in sequence. The driving gear 304 is coaxially connected to the end of the output shaft of the driving motor 305, which is meshed and matched with the working wheel disc 303, and can realize the rotation control of the working wheel disc 303.

[0052] The working wheel 303 in the preferred embodiment is coaxially arranged with the support member 202, and is rotatably arranged below the ammunition placement hole, and a receiving groove is opened in the middle corresponding to the shape of the wrench body 301; the wrench body 301 in the preferred embodiment is as shown Figure 7 As shown in , the middle part is a circular block structure, and branches are symmetrically arranged on both sides of the circular structure, and a specific wrench groove is opened at the bottom of the circular structure, such as Figure 7 , 8 as shown in .

[0053] By correspondingly embedding the wrench body 301 in the accommodating groove on the working wheel disc 303 , the wrench body 301 and the working wheel disc 303 can be limited and fixed in the circumferential position, so that the wrench body 301 can rotate synchronously with the working wheel disc 303 .

[0054] In a preferred embodiment, the shape of the wrench groove is similar to the shape of the wrench body 301, that is, it includes a circular groove in the middle and long branch grooves arranged on both sides of the circular groove. With the arrangement of the wrench groove, it can match the top wrench protrusion of the disassembly seat 302, and then the disassembly seat 302 is driven by the wrench body 301 to rotate, thereby completing the disassembly of the corresponding first part 503 to be disassembled.

[0055] like Fig. 9 As shown in the figure, the top of the disassembly seat 302 in the preferred embodiment is provided with a wrench protrusion corresponding to the wrench groove in the middle of the wrench body 301, and the wrench protrusion can be correspondingly embedded in the wrench groove to realize the assembly connection between the wrench body 301 and the disassembly seat 302. At the same time, the bottom of the disassembly seat 302 is used to match the corresponding first part 503 to be disassembled at the end of the ammunition 5. In actual setting, the first part 503 to be disassembled is preferably a compression screw with a groove on the surface. Therefore, in the preferred embodiment, the end of the disassembly seat 302 away from the wrench protrusion is provided with a corresponding protrusion or convex strip, so that the assembly between the disassembly seat 302 and the first part 503 to be disassembled is realized through the corresponding matching between the protrusion and the groove.

[0056] It can be understood that, according to the different models and setting positions of the first to-be-removed part 503, the end structure and length size of the disassembly seat 302 in the preferred embodiment can also be set to be different, that is, the disassembly seat 302 can be set to a variety of models and specifications as needed. Of course, the end of the disassembly seat 302 of each model provided with the wrench protrusion can be set to a fixed structure to universally match the corresponding wrench body 301.

[0057] As another specific embodiment of the present invention, an ammunition disassembly method based on the above-mentioned ammunition disassembly device is also disclosed, and its main process is preferably as follows: (1) The ammunition 5 to be disassembled is placed into the equipment body 4 placed in the explosion-proof room through the ammunition placement hole on the workbench 402, and the bottom of the ammunition 5 is supported by the support member 202, and the body 501 of the ammunition 5 is clamped by the clamping member 201; In actual operation, the vertical position of the support member 202 can be adjusted by the lifting mechanism 203 according to the length of the ammunition 5. Similarly, when placing the ammunition 5 vertically, it is preferred to first adjust the support member 202 to a higher position. At this time, the height of the support member 202 from the workbench 402 is less than the length of the ammunition 5. In this way, the collision of the ammunition 5 during the placement process can be avoided, and the reliability of the setting of the ammunition 5 can be ensured. After completing the above settings, the support member 202 is vertically lowered to the corresponding position, and then the clamping member 201 completes the clamping of the projectile 501.

[0058] (2) Select the corresponding disassembly seat 302 and match it to the end of the ammunition 5.
