Description

Technical Field

[0001] The invention belongs to the technical field of ammunition assembly, and particularly relates to an automatic ammunition assembling and hard closing machine. Background Art

[0002] During the assembly process of a shell, the shell body and the warhead need to be assembled and closed, and there are requirements for the assembly force. The existing assembly and closing process is generally as follows: Manually position the shell body and the warhead on both sides of the closing machine, and manually push the slide plate to dock the warhead and the shell body. Use the oil cylinder to apply the assembly force to the shell body to assemble the shell body and the warhead. After assembly, start the closing fixture to close the joint of the warhead and the shell body. The assembly and closing process is semi-automatic or completely manual, which requires manual participation. It not only has a large labor intensity, low production efficiency, cannot achieve real-time detection, but also has a certain degree of danger. There is no equipment in the domestic shell production field that can achieve automatic assembly and hard closing.

One end of the die driving oil cylinder 603 is hinged to the hinge seat of the die connecting slide 602, and the other end is respectively hinged to the other ends of the two sets of connecting rod A 605.

[0074] The die driving oil cylinder 603 extends, successively driving the connecting rods A 605, spline shaft 604, connecting rod B 606 and connecting rod C 607 of two groups to act, so that the connecting rods C 607 of two groups jointly drive the die holder of the necking machine die 5 to act, in order to neck the assembled projectile 001 and warhead 002; when the die driving oil cylinder 603 retracts, the die holder of the necking machine die 5 returns to the initial position. In this embodiment, the die driving oil cylinder 603 is a commercially available product, connected to the hydraulic system 9 of the necking machine and controlled by an external controller.

[0075] Working principle:

[0076] The projectile 001 is transported to the rear slide plate assembly 2 by the handling robot on the production line. The tail end of the projectile 001 abuts against the support block 205, and the front end of the projectile 001 is seated on the projectile support block 206; then the handling robot transports the warhead 002 to the warhead support assembly 3.

[0077] After the transportation is completed, the front slide plate 401 is driven by the front slide plate driving member 8 to horizontally slide along the guide rail C 408 towards the warhead 002. The cartridge carrier connecting rod 405 passes through the inner hole of the swaging die 5. When it moves to the specified position, the cartridge carrier 406 contacts the warhead 002, and its annular surface wraps around and contacts the warhead 002. At this time, the rear slide plate 201 is driven by the rear slide plate driving member 7 to horizontally slide along the guide rail A 208 towards the projectile body 001. After moving to the specified assembly position, the rear slide plate 201 stops moving. The assembly position of the rear slide plate assembly 2 is fixed, and the rear slide plate driving member 7 ensures its precise position. At this time, the rear slide plate assembly 2 and the front slide plate assembly 4 jointly hold the projectile body 001 and the warhead 002. The lifting driving member 303 retracts, the warhead support block 305 drops, and the rear slide plate driving member 7 continues to drive the rear slide plate 201 to move further towards the warhead 002 to achieve assembly. At this time, the driving end of the rear slide plate driving member 7 abuts against the force measuring structure 203. The force measuring structure 203 is stressed and pushes the rear slide plate driving member connecting seat 202. The rear slide plate driving member connecting seat 202 abuts against the projectile body push plate 204, causing the rear slide plate 201 to slide forward along the guide rail A 208. The front slide plate 401 is pushed by the rear slide plate assembly 2 and horizontally moves uniformly along the guide rail C 408 in the direction of the initial position of the front slide plate 401. The front slide plate driving member 8 is retracted passively. The front slide plate assembly 4 and the rear slide plate assembly 2 jointly support the projectile body 001 and the warhead 002 at both ends of the product and move them towards the swaging die 5. The warhead 002 passes through the swaging die 5, and the cartridge belt part of the product composed of the projectile body 001 and the warhead 002 fits with the inner contour of the profiling module inside the swaging die 5. At this time, the product assembly is completed and reaches the swaging position. During the assembly process, the force measuring structure 203 real-time detects the assembly force and displacement, and real-time feeds back the signal to the rear slide plate driving member 7 to achieve closed-loop control and precisely complete the assembly of the warhead 002 and the projectile body 001.

[0078] After the product reaches the swaging position and the assembly is completed, the rear slide plate driving member 7 and the front slide plate driving member 8 stop moving. At this time, the cartridge belt is inside the swaging die 5. The swaging machine hydraulic system 12 drives the die driving oil cylinder 603 to extend, sequentially driving the two groups of link A 605, spline shaft 604, link B 606 and link C 607 to act, so that the two groups of link C 607 jointly drive the die seat of the swaging die 5 to act to swage the assembled projectile body 001 and warhead 002.

[0079] After the necking is completed, the die driving oil cylinder 603 retracts, the die seat of the necking machine die 5 returns to the initial position and releases the product that has completed the assembled necking. The rear slide driving member 7 retracts. The front slide 401 drives the rear slide assembly 2 to move in the direction of the rear slide driving member 7 under the drive of the front slide driving member 8, and transports the product back to the initial position. When the rear slide 201 and the front slide 401 reach the position, the lifting driving member 303 extends, and the warhead support block 305 rises, and the warhead support assembly 3 provides support for the product. At this time, the front slide assembly 4 disengages from the product and returns to the initial position under the drive of the front slide driving member 8. After the movement of the necking machine stops, the handling robot removes the finished product, and each component is in the initial position, waiting to perform the assembled necking for the next product.
