Description

Technical Field

[0001] This utility model relates to the field of projectile parts processing, and more specifically, it relates to a projectile parts propellant loading tool. Background Technology

[0002] Modern warfare primarily utilizes low-altitude and ultra-low-altitude defensive munitions, including high-explosive incendiary grenades, tracer high-explosive incendiary grenades, tracer armor-piercing high-explosive incendiary grenades, multi-purpose grenades, cluster-directed pre-fragmented projectiles, and cluster-penetrating incendiary grenades. These types of munitions all require the insertion of an appropriate amount of explosives into their bodies or components to meet the stringent requirements of modern warfare.

[0003] The patent with publication number CN217110689U discloses a small-caliber ammunition pressing fixture, which includes a mold base assembly, a trolley assembly slidably disposed on the mold base assembly, a punch assembly disposed above the mold base assembly, and a driving component for driving the punch assembly to move vertically; the trolley assembly includes a trolley, on which multiple placement columns are connected, and the top of the placement columns is provided with a cavity for placing the projectile; the mold base assembly includes a base plate, on which a positioning component for positioning the trolley assembly is provided; the punch assembly includes a punch mounting seat, on which multiple punches are mounted, and all punches correspond one-to-one with all cavities.

[0004] The above-mentioned explosive pressing fixture can perform step-by-step pressing operations on multiple projectiles at the same time, which greatly improves the efficiency and consistency of batch loading. However, when pressing aluminum projectile parts with explosives, the aluminum projectile parts are relatively thin, which can easily cause the projectile parts to deform during the explosive pressing process, thus making them unusable for subsequent assembly.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a propellant pressing fixture for projectile parts. This fixture can cooperate with the propellant pressing assembly through positioning block one and positioning block two to ensure that the compressed propellant powder can form a cylindrical propellant column inside the projectile part body and avoid deformation of the part.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a projectile part pressing tooling includes a base plate, a positioning block one is fixedly connected to the base plate, a plurality of positioning rods are fixedly connected to the positioning block one, the other end of the positioning rods is fixedly connected to the base plate, a positioning block two is slidably connected to the positioning rods, a projectile part body is detachably connected to the positioning block one, when the positioning block one and the positioning block two are in contact with each other, the projectile part body is detachably connected to the positioning block two, and the positioning block two is provided with a pressing component for pressing explosive.

[0008] The present invention is further configured such that: the drug-pressing assembly includes a plurality of fixed rods fixedly connected to the positioning block two, a sliding ring slidably connected to the plurality of fixed rods, and a drug-pressing punch fixedly connected to the sliding ring; a spring is sleeved on the fixed rod between the positioning block two and the sliding ring; and a driving component is provided on the base plate for driving the sliding ring to slide downward.

[0009] The present invention is further configured such that a limiting sleeve is fixedly connected to the sliding ring.

[0010] The present invention is further configured such that: the driving component includes an electric push rod fixedly connected to the base plate and a pressure plate fixedly connected to the telescopic end of the electric push rod; when the first spring is in a normal state and the first positioning block and the second positioning block are in contact with each other, the pressure plate and the sliding ring are in contact with each other.

[0011] The present invention is further configured such that: both positioning block one and positioning block two are slidably connected to sliding rods, and pushing blocks and fixing blocks are respectively fixedly connected to both ends of the sliding rods; and spring two is sleeved on the sliding rods, with the two spring two respectively located between positioning block one and the adjacent fixing block and between positioning block two and the adjacent fixing block.

[0012] The present invention is further configured such that a guide ring is fixedly connected to the positioning block.

[0013] In summary, this utility model has the following beneficial effects: the positioning block one and positioning block two can cooperate with the propellant pressing assembly to ensure that the compressed powder can form a cylindrical propellant column inside the projectile part body and avoid deformation of the part.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] A projectile component propellant loading fixture, such as Figures 1-3 As shown, the device includes a base plate 1, a positioning block 2 fixedly connected to the base plate 1, a plurality of positioning rods 3 fixedly connected to the positioning block 2, the other end of the positioning rods 3 fixedly connected to the base plate 1, a positioning block 4 slidably connected to the positioning rods 3, a projectile part body 5 detachably connected to the positioning block 2, and the projectile part body 5 detachably connected to the positioning block 4 when the positioning block 2 and the positioning block 4 are in contact with each other. The positioning block 4 is provided with a pressing assembly for compacting explosives. The pressing assembly includes a plurality of fixing rods 6 fixedly connected to the positioning block 4, a sliding ring 7 slidably connected to the plurality of fixing rods 6, and a pressing punch 8 fixedly connected to the sliding ring 7. A spring 9 is sleeved between the fixing rods 6 and the sliding ring 7. The base plate 1 is provided with a driving component for driving the sliding ring 7 to slide downwards.

[0018] like Figures 1-3 As shown, when loading explosives onto the projectile body 5, the projectile body 5 is first installed on positioning block 1 2. Then, explosives are poured into the through hole of positioning block 1 2. The explosives will then enter the projectile body 5 through the through hole of positioning block 1 2. At this time, the explosives will be blocked and retained inside the projectile body 5 by positioning block 1 2. Then, positioning block 2 4 is manually pushed close to positioning block 1 2 and then pressed against positioning block 2 4. At this time, positioning block 2 4 will also press against the projectile body 5 to prevent deformation of the projectile body 5 during loading. Then, the drive mechanism is activated, which will drive the sliding mechanism. The moving ring 7 moves downwards, driving the charging punch 8 into the through hole of the positioning block 2. The charging punch 8 then continues to move downwards, driving the explosive in the positioning block 2 into the projectile body 5 and compacting the explosive in the projectile body 5. At this time, the spring 9 is in a compressed state. Then, the drive component is activated to reset, and the spring 9 will also reset, driving the sliding ring 7 and the charging punch 8 to move upwards. When the charging punch 8 is no longer in contact with the projectile body 5 and the positioning block 2, the positioning block 4 is manually pushed away from the positioning block 2, and the projectile body 5 can be taken out for assembly.

[0019] like Figure 1 , Figure 3 As shown, a limiting sleeve 10 is fixedly connected to the sliding ring 7. When the driving component moves the sliding ring 7 downward, it will also move the limiting sleeve 10 downward simultaneously. When the punch 8 enters the through hole of the positioning block 1 2 and moves to the middle section, the limiting sleeve 10 will contact the positioning block 1 2 and the positioning block 2 4. When the limiting sleeve 10 continues to move downward at this time, the limiting sleeve 10 will be sleeved on the positioning block 1 2 and the positioning block 2 4. This can prevent the positioning block 2 4 from moving away from the positioning block 1 2 during the pressing of the explosive, which would cause the projectile parts to deform.

[0020] like Figures 1-3As shown, the driving component includes an electric push rod 11 fixedly connected to the base plate 1 and a pressure plate 12 fixedly connected to the telescopic end of the electric push rod 11. When the spring 9 is in the normal state and the positioning block 2 and the positioning block 4 are in contact with each other, the pressure plate 12 and the sliding ring 7 are in contact with each other. When it is necessary to drive the sliding ring 7 to slide downward, the electric push rod 11 can be activated to retract and drive the pressure plate 12 to move downward. At this time, if the pressure plate 12 is in contact with the sliding ring 7, it will drive the sliding ring 7 to move downward synchronously.

[0021] like Figures 1-3 As shown, both positioning block 2 and positioning block 4 are slidably connected to sliding rods 13. Pushing blocks 14 and fixing blocks 15 are fixedly connected to both ends of the sliding rods 13, respectively. Springs 16 are sleeved on the sliding rods 13. The two springs 16 are located between positioning block 2 and the adjacent fixing block 15, and between positioning block 4 and the adjacent fixing block 15, respectively. When the propellant is pressed, and positioning block 4 is manually moved away from positioning block 2, the projectile body 5 may be stuck on positioning block 2 or positioning block 4. When the projectile body 5 is stuck on positioning block 2... Press the fixing block 15 adjacent to the positioning block 2, so that the sliding rod 13 slides inside the positioning block 2. At this time, the spring 16 will be in a compressed state. Then the pushing block 14 adjacent to the positioning block 2 will push out the projectile part body 5 that is stuck on the positioning block 2. If the projectile part body 5 is stuck on the positioning block 4, press the fixing block 15 adjacent to the positioning block 4 in the same way. After the projectile part body 5 is taken out, stop pressing the fixing block 15. The spring 16 will reset and drive the fixing block 15 to reset, so as to facilitate the insertion of the next projectile part body 5.

[0022] like Figure 1 , Figure 3 As shown, a guide ring 17 is fixedly connected to the positioning block 2, which makes it easier and faster to pour explosives into the body 5 of the projectile component.

[0023] Working principle: When it is necessary to load explosives onto the projectile body 5, the projectile body 5 is first installed on the positioning block 1 2. Then, explosives are poured into the through hole of the positioning block 1 2. The explosives will then enter the projectile body 5 through the through hole of the positioning block 1 2. At this time, the explosives will be blocked and retained inside the projectile body 5 by the positioning block 1 2. Then, the positioning block 2 4 is manually pushed close to the positioning block 1 2 and is in contact with the positioning block 2 4. At this time, the positioning block 2 4 will also be in contact with the projectile body 5 to prevent the projectile body 5 from deforming during the loading of explosives. Then, the electric push rod 11 is activated. The electric push rod 11 will drive the pressure plate 12 to move downward. Then, the pressure plate 12 will drive the sliding ring 7 to move downward and drive the loading punch 8 into the through hole of the positioning block 1 2. When the loading punch 8 enters the through hole of the positioning block 1 2 and moves to the middle section, the limiting sleeve 10 will engage with the positioning block 1 2. Positioning block 12 and positioning block 24 are in contact. When the limiting sleeve 10 continues to move downward, the limiting sleeve 10 will be fitted onto positioning block 12 and positioning block 24. This prevents positioning block 24 from moving away from positioning block 12 when pressing the explosive. Then, the pressing punch 8 continues to move downward, which will drive the explosive in positioning block 12 into the body of the projectile part 5 and compact the explosive in the body of the projectile part 5. At this time, spring 19 is in a compressed state. Then, the electric push rod 11 is activated to drive the pressure plate 12 to reset. Spring 19 will also reset and drive the sliding ring 7 and the pressing punch 8 to move upward. When the pressing punch 8 is no longer in contact with the body of the projectile part 5 and positioning block 12, the positioning block 24 is manually pushed away from positioning block 12. Then, according to the position of the body of the projectile part 5, the adjacent fixing block 15 is pressed. In this way, the body of the projectile part 5 can be taken out for assembly.
