Description

Technical Field

[0001] The present invention belongs to the field of ammunition assembly, and specifically relates to an automatic ammunition assembling and soft 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. In the existing assembly and closing process, the shell body and the warhead are manually positioned on both sides of the closing machine, and the sliding table is manually pushed to assemble the warhead and the shell body. After assembly, the joint of the warhead and the shell body is closed by a closing fixture. The existing 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 closing. There is an urgent need for an automatic assembly and closing equipment with high automation, which can ensure the assembly accuracy and achieve real-time detection. Summary of the Invention

[0042] As Figure 8 shown, the disc spring assembly 26 of this embodiment is a prior art, including a disc spring mounting seat 56, a disc spring pressing cover 57, a disc spring pressing plate 58 and a disc spring. One end of the disc spring mounting seat 56 is connected to the other end of the tooling connecting part 24.

When the sliding table assembly 2 moves along the guide rail 3 to the assembling position, the stop block cylinder 32 drives the stop block 36 to rise into the hollow groove 50 and abut against the baffle 20, so that the sliding of the sliding table assembly 2 in the sliding direction is locked.

[0044] AsFigure 1 , Figure 2 and Figure 10 As shown in Figure 1 , Figure 2 and Figure 10 , the automatic ammunition assembling and soft closing machine of the present invention further includes an electric cylinder assembly 10, and the electric cylinder assembly 10 is fixed at one end of the mounting seat 1 away from the slide table assembly 2.

The explosion-proof servo motor 39 is connected to the input end of the electric cylinder 40. A disc type weighing sensor 37 is installed on the electric cylinder connecting rod 38 which is the output end of the electric cylinder 40. The explosion-proof servo motor 39 drives the electric cylinder 40, so that the electric cylinder connecting rod 38 drives the disc type weighing sensor 37 to stretch along the sliding direction of the slide table assembly 2 and the front slide plate assembly 11 (i.e., along the guide rail 3); during assembling, the disc type weighing sensor 37 extends out to press on the disc spring pressing plate 58 of the disc spring assembly 26 to provide an assembling force, and the assembling force is transmitted to the front slide plate assembly 11 and then to the warhead 8. At the same time, the disc type weighing sensor 37 detects the force and displacement during assembling; the disc spring assembly 26 has elasticity and is used for transmitting the assembling force. The disc type weighing sensor 37 of this embodiment is prior art and will not be elaborated here.

[0045] As Figure 1 , Figure 2 and Figure 11 As shown in , Figure 2 and Figure 11 , the projectile support assembly 6 of this embodiment includes a projectile support cylinder connecting plate 41, a projectile support cylinder 42, a projectile support 43 and a polytetrafluoroethylene cushion block 44. The projectile support cylinder connecting plate 41 is fixed on the mounting seat 1. The projectile support cylinder 42 is installed on the projectile support cylinder connecting plate 41. The projectile support 43 is installed at the output end of the projectile support cylinder 42 and rises and falls with the extension and retraction of the projectile support cylinder 42, and is used for receiving the warhead 8 and assisting in assembling. The contact surface between the projectile support 43 and the warhead 8 is an arc surface adapted to the shape of the warhead 8, and a polytetrafluoroethylene cushion block 44 is installed on the arc surface to prevent damage and scratching of the product.

[0046] The working principle of the present invention is:

[0047] The projectile body 5 is carried by the handling robot on the production line to the sliding table assembly 2. The tail end of the projectile body 5 abuts against the cartridge groove, and the middle section is located on the cartridge bracket 21. Then, the projectile support frame 43 is lifted by the projectile support cylinder 42, and the handling robot then transports the warhead 8 to the projectile support assembly 6. After the handling is completed, the front slide plate assembly 11 is driven by the cylinder B53 to slide horizontally along the guide rail 3 towards the direction of the warhead 8. The tooling connecting rod 24 passes through the sizing die 9 of the sizing machine and slides to the designated position. At this time, the projectile pushing tooling 23 comes into contact with the warhead 8. At this time, the projectile support cylinder 42 retracts, the projectile support frame 43 drops, and the sliding table assembly 2 is driven by the cylinder A7 to slide horizontally in the opposite direction along the guide rail 3. The cylinder B53 of the front slide plate assembly 11 is exactly the same as the cylinder A7 of the sliding table assembly 2, but is equipped with a pressure reducing valve. At this time, the front slide plate assembly 11 is horizontally pushed by the sliding table assembly 2 along the guide rail 3 towards the direction of the electric cylinder assembly 10. The front slide plate assembly 11 and the sliding table assembly 2 jointly support the projectile body 5 and the warhead 8 at both ends of the product and slide towards the direction of the electric cylinder assembly 10. At this time, the warhead 8 passes through the sizing die 9 of the sizing machine, and the driving band fits with the internal profiling contour. At this time, the product reaches the assembling position. When reaching the designated position, the stop block 36 is lifted by the stop block cylinder 32 and passes through the hollow groove 50 of the slide plate 15 to contact the baffle plate 20. The explosion-proof servo motor 39 drives the electric cylinder 40, so that the electric cylinder connecting rod 38 extends out, and the top disc type weighing sensor 37 presses against the disc spring assembly 26, pushing the front slide plate assembly 11. Since the position of the sliding table assembly 2 is locked by the 6° wedge angle of the stop block assembly 4, at this time, the assembling force is applied to the warhead 8. The disc type weighing sensor 37 detects the force and displacement in real time and feeds the signal back to the explosion-proof servo motor 39 in real time to achieve closed-loop control and accurately complete the assembly of the warhead 8 and the projectile body 5.

[0048] After the assembly is completed, the electric cylinder assembly 10 retracts and the force application stops. At this time, the driving band is inside the sizing die 9 of the sizing machine, and the sizing machine hydraulic system 12 drives the sizing die 9 to close. The profiling inner contour of the sizing die 9 tightens and envelopes the part of the driving band to complete the sizing of the product.

[0049] After the sizing is completed, the stop block cylinder 32 retracts, the stop block 36 drops, and the sliding table assembly 2 and the front slide plate assembly 11 jointly move in the opposite direction of the electric cylinder assembly 10 under the action of the two cylinders to transport the product back to the initial position. When the sliding table assembly 2 and the front slide plate assembly 11 move in place, the projectile support cylinder 42 extends, the projectile support frame 43 rises, and the projectile support assembly 6 provides support for the product. At this time, the front slide plate assembly 11 disengages from the product and returns to the initial position. The handling robot removes the finished product, and each component is in the initial position, waiting to assemble and size the next product. During the entire assembly and sizing process, the cylinder actions are simple, and there is positioning during assembly, which can ensure the fixed position of the product at each moment.

[0050] The above are only embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, expansions, etc. made within the spirit and principle of the present invention are all included in the protection scope of the present invention.
