Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0018] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a projectile and propellant combination device, which consists of a combination worktable 1, a projectile transmission assembly 2, a propellant fixing chuck 3, a propellant support 4 and a projectile support 5. The combined workbench 1 consists of a workbench support and a top base plate, which are securely connected by screws and grounded. The screw fixing method facilitates subsequent disassembly and allows for the combination of projectiles and propellant loading on the combined workbench 1.

[0019] The projectile transmission assembly 2 and the propellant fixing chuck 3 are respectively fixedly installed on both sides of the connecting workbench 1 to realize the pushing and rotating combination of the projectile and the propellant. The projectile transmission assembly 2 includes a support base plate 24 connected to the top base plate for the operation and installation of the projectile transmission assembly 2, allowing it to be disassembled as a whole. Ball screw support seats 25 and projectile sleeve support seats 26 are respectively installed on both sides of the support base plate 24, so that the projectile sleeve connecting shaft 28 and the ball screw 23 can be stably supported by the forces on both sides, making the force more even during pushing and rotating. A ball screw 23 is connected to one side of the ball screw support seat 25 through a ball screw nut 27, and a handwheel 22 is fixedly connected to the outside of the ball screw 23, making it easy for the operator to drive the ball screw 23 to rotate and push, making operation more convenient. The projectile sleeve support seat 26 is internally connected to the projectile sleeve connecting shaft 28. One side of the projectile sleeve 28 is connected to the other side of the ball screw 23 via a connecting sleeve 29, and the other side of the projectile sleeve connecting shaft 28 is connected to the projectile sleeve 21 via screws. The projectile sleeve 21 is moved by pushing the projectile sleeve connecting shaft 28, thereby adjusting the position of the projectile for processing. The screw fixing method allows the projectile sleeve 21 to be disassembled according to different projectiles, making it suitable for different caliber ammunition. The propellant fixing chuck 3 includes a side bearing seat connected to the top base plate. The propellant chuck connecting shaft is connected in the side bearing seat. The propellant chuck is connected to the inner side of the propellant chuck connecting shaft, and a rocker wheel is connected to the other side of the propellant chuck connecting shaft. The propellant can be fixed by the propellant chuck, and the propellant can be rotated by manually turning the rocker wheel, which drives the propellant chuck to rotate and adjust its position, thus facilitating the operation.

[0020] The propellant support 4 and the projectile support 5 are respectively located between the projectile transmission assembly 2 and the propellant fixing chuck 3 to achieve stable support for the projectile and the propellant. The propellant support 4 includes two bearing seats mounted on the top side plate of the propellant fixing chuck 3 via the support base plate. The projectile support 5 includes four bearing seats mounted on the top side plate of the projectile transmission assembly 2 via the support base plate. Each bearing seat is equipped with two standard bearings, which can effectively increase the contact area between the projectile and the propellant, increase the supporting force, and ensure stable support.

[0021] Work steps: (1) First, prepare the pre-assembled projectile and propellant, rotate the handwheel 22 on the projectile transmission assembly 2, and move the projectile sleeve 21 to the initial working position (distance to the propellant fixing chuck 3 > projectile length + propellant length). (2) Two operators lift the projectile and the propellant respectively, place the bottom of the propellant into the propellant fixing chuck 3, and at the same time make the projectile and the propellant stable on the propellant support 4 and the projectile support 5. (3) An operator turns the handwheel 22 on the projectile transmission assembly 2 and stops turning the handwheel 22 when the projectile sleeve 21 is moved to 2 / 3 of the projectile head is submerged in the projectile sleeve 21. (4) Two operators simultaneously rotate the handwheel 22 and the rocker wheel of the projectile transmission assembly 2 and the propellant chuck 3 to advance the projectile into the propellant. After observing that the projectile has been advanced to the appropriate engagement position, they stop rotating the handwheel 22 and the rocker wheel. (5) Use tooling to secure and tighten the propellant charge along the tightening groove; (6) Two operators simultaneously rotate the handwheel 22 and the rocker wheel on the fixed seat of the projectile transmission assembly 2 and the propellant chuck 3 to eject the projectile sleeve 21 from the projectile; (7) Two operators lift the projectile and the propellant respectively to remove the combined ammunition from the device and place it in the designated position; (8) Perform the actions of each workstation in cycle 2, 3, 4, 5, 6, and 7.
