[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0018] like Figure 1 and Figure 2 As shown, a positioning connector for a shell loading and unloading machine includes: an electric cylinder 20, which is installed on the loading and unloading machine and electrically connected to a power source. This solution is symmetrically arranged on the loading and unloading machine. The symmetrical electric cylinders 20 are synchronously controlled by a master PLC and an EtherCAT high-speed bus. This is existing technology and will not be described in detail here.
[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the self-retracting structure is located at the retracting end of the electric cylinder 20 for clamping the projectile. The self-retracting structure includes: a frame 31, a trigger frame 36, and clamping rods 37. The frame 31 is movably located at the retracting end of the electric cylinder 20. The trigger frame 36 is located in front of the frame 31. The clamping rods 37 are symmetrically arranged on both sides of the frame 31 and can move on the wall surface of the frame 31.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the frame 31 is a rectangular plate with circular slots running through its top two sides. The clamping rod 37 is a U-shaped rod with a cylinder fixedly connected to its rear end. The cylinder of the clamping rod 37 is inserted into the circular slot on the wall of the frame 31. The trigger frame 36 is a rectangular frame. The self-retracting structure also includes a rotating cylinder 30, side slots 32, a sliding rod 33, a pull rail 34, a sliding groove 35, and a sliding column 38. The rotating cylinder 30 is rotatably connected to the telescopic end of the electric cylinder 20. A disc is fixedly connected to the telescopic end of the electric cylinder 20, and the rear wall of the disc can contact the front wall of the rotating cylinder 30. The frame 31 is fixedly connected to the front wall of the rotating cylinder 30. The side slots 32 are symmetrically opened on both sides of the frame 31. The sliding rod 33 is slidably connected to the front wall of the frame 31. The trigger frame 36 is fixedly connected to the sliding rod. The front wall of the slide rod 33 has a pull rail 34 symmetrically fixedly connected to the upper and lower walls of the slide rod 33. The slide groove 35 is opened through the top of each pull rail 34. The slide column 38 is fixedly connected between the upper and lower symmetrical clamping rods 37 on each side. The rotating cylinder 30 is in the shape of a round tube. The cavity of the rotating cylinder 30 can be adapted to the telescopic end of the electric cylinder 20 and the rotation of the disc on the wall of the electric cylinder 20. The rear wall of the frame 31 can fit with the disc. The slide rod 33 is in the shape of a U-shaped rod. The opening of the rear wall of the slide rod 33 can be engaged in the symmetrical side groove 32. Rectangular blocks are fixedly connected to the upper and lower walls at both ends of the rear wall of the slide rod 33. The slide groove 35 is in the shape of a capsule. The slide column 38 on each side can slide in the cavity of the symmetrical slide groove 35 on each side. The slide groove 35 can be adapted to the size of the slide column 38. The slide column 38 is in the shape of a round rod. In practical use, when it is necessary to fix the shell, the shell to be fixed is placed between the symmetrical trigger frames 36, and the two electric cylinders 20 are controlled to extend synchronously. As the electric cylinders 20 extend, they can drive all the structures on their contraction end walls to move synchronously. When the trigger frames 36 move with the extension of the electric cylinders 20, the trigger frames 36 will first contact the shell wall. Then, as the trigger frames 36 contact the shell, the limiting ring 21 will still gradually extend, and the fixing frame 31 will still move because the trigger frames 36 stop. At this time, the sliding rod 33 will move because the trigger frames 36 stop. The slide bar 33 slides within the side groove 32. As the slide bar 33 slides, it drives the pull rail 34 to slide synchronously. At this time, the slide column 38, being within the slide groove 35, is driven to tighten the symmetrical clamping rod 37 towards the other clamping rod 37. The symmetrical clamping rod 37 tightens to clamp and fix the shell. Once the symmetrical clamping rod 37 has completely clamped the shell, the extension of the limiting ring 21 can be stopped. At this point, the shell will be clamped and fixed by the two sets of symmetrical clamping rods 37, allowing for shell assembly and disassembly. After the shell assembly and disassembly are completed, the retraction end of the control cylinder 20 retracts to unlock the shell. In summary, by setting a self-retracting structure, the outer wall of the projectile can be adaptively clamped and fixed by two sets of symmetrically arranged movable clamping rods 37. Not only can it be achieved with only two sets of symmetrical clamping rods 37, but it can also fix the outer wall of projectiles of different sizes.
[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the telescopic end of the electric cylinder 20 is also equipped with a rotating structure, which includes: a limiting ring 21, a fixed block 22, a spring piece 23, a lever ring 24, and a locking groove 25. The limiting ring 21 is fixedly connected to the outer wall of the telescopic end of the electric cylinder 20, the fixed block 22 is fixedly connected to the front wall of the limiting ring 21, the spring piece 23 is fixedly connected to the wall of the fixed block 22, the lever ring 24 is fixedly connected to the outer wall of the rotating cylinder 30, and the locking groove 25 is opened on the outer arc surface of the rotating cylinder 30. The fixed block 21 is fixedly connected to the outer wall of the rotating cylinder 30, the fixed block 22 is fixedly connected to the outer wall of the rotating cylinder 30, and the locking groove 25 is opened on the outer arc surface of the rotating cylinder 30. 2. Multiple spring pieces 23 are arranged in a ring array on the front wall of the limiting ring 21. The spring pieces 23 are fixedly connected to the wall of the fixed block 22 facing the center of the limiting ring 21. The spring pieces 23 are arc-shaped pieces. The wall of each fixed block 22 is provided with the same spring pieces 23. The locking groove 25 is an arc-shaped groove. The outer arc surface of the spring piece 23 can be engaged in the locking groove 25. The dial ring 24 is a circular ring with an anti-slip groove on the outer arc surface. The front wall of the dial ring 24 can also be fixedly connected to the rear wall of the limiting ring 21. In practical use, when it is necessary to fix the shell horizontally, hold the lever 24 and rotate the lever 24 ninety degrees along the telescopic end of the electric cylinder 20. When the lever 24 is rotated, it will drive the rotating cylinder 30 to rotate synchronously. The rotating cylinder 30 will drive the structure including the symmetrical clamping rods 37 to rotate synchronously. At this time, the two symmetrical clamping rods 37 will be transformed into vertically symmetrical clamping rods 37. At this time, it can be used with another set of symmetrical clamping rods 37 to fix the shell horizontally. When the rotating cylinder 30 rotates with the lever 24, the shell piece 23 will be inserted into the corresponding locking groove 25 to limit the rotating cylinder 30. The locking groove 25 is made of memory metal. In summary, by setting up a rotating structure, the symmetrical clamping rod 37 can be rotated by manually rotating the dial 24, thereby changing its position. This allows the projectile to be fixed not only vertically but also horizontally.
[0022] Working principle: When it is necessary to fix the shell, the shell to be fixed is placed between the symmetrical trigger frames 36, and the two electric cylinders 20 are controlled to extend synchronously. As the electric cylinders 20 extend, they can drive all the structures on their contraction end walls to move synchronously. When the trigger frames 36 move with the extension of the electric cylinders 20, the trigger frames 36 will first contact the shell wall. Then, as the trigger frames 36 contact the shell, the limiting ring 21 will still gradually extend, while the fixing frame 31 will still be fixed due to the stop of the trigger frames 36. When the slide bar 33 moves, it will slide in the side groove 32 because the trigger frame 36 is stationary. As the slide bar 33 slides, it will drive the pull rail 34 to slide synchronously. At this time, the slide column 38 will be driven by the symmetrical clamping rod 37 to tighten towards the clamping rod 37 on the other side because it is in the slide groove 35. Then the symmetrical clamping rod 37 will tighten to clamp and fix the shell. After the symmetrical clamping rod 37 has completely clamped the shell, the extension of the limiting ring 21 can be stopped. At this time, the shell will be clamped and fixed by the two sets of symmetrical clamping rods 37.
