Description

Technical Field

[0001] This invention relates to a warhead injection device, belonging to the field of warhead loading technology. Background Technology

[0002] Explosives are frequently used in various engineering and civilian blasting operations. Explosive loading involves heating and melting solid explosives, processing them, injecting them into empty projectiles, and then allowing them to cool and solidify to form a specific shape and size. In current explosive production, automated or semi-automatic loading equipment is widely used to ensure precise, quantitative, and standardized loading.

[0003] According to the melt-injection process, after the melt-injection charge is completed and the detonator assembly is installed, silicone rubber should be injected into the projectile body to fill the space between the detonator assembly and the explosive surface, serving to fill, seal, and protect it. However, in existing technologies, there are often situations where secondary injection of silicone rubber is required due to inaccurate injection volume, thus affecting the production efficiency of explosives.

Detailed Implementation

[0021] To better understand the essence of the present invention, the present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0022] This invention relates to the automatic lifting, weighing, and glue injection of warheads after the detonation tube assembly has been installed, specifically to a warhead glue injection device, such as... Figures 1 to 3 As shown, the device includes a positioning device 1, a glue-dispensing funnel 3, a weighing device, a translation device 5, and a lifting device 6. The glue-dispensing funnel 3 and the weighing device are sequentially mounted on the translation device 5, and the translation device 5 is slidably connected to the lifting device 6; the lifting device 6 is used to lift the glue-dispensing funnel 3 above the positioning device 1.

[0023] like Figure 2 As shown, the positioning device 1 is equipped with a gripper translation extension mechanism 7, a projectile clamping mechanism 8, and a gripper 9. The gripper translation extension mechanism 7 is fixed to the positioning device 1. The end of the gripper 9 is rotatably connected to the projectile clamping mechanism 8, and its front end extends to the outside of the positioning device 1. The gripper 9 is used to clamp the projectile 2. The projectile clamping mechanism 8 is slidably connected to the gripper translation extension mechanism 7. The gripper translation extension mechanism 7 can be a slide rail or a slide groove. The projectile clamping mechanism 8 is provided with a sliding component that matches the gripper translation extension mechanism 7, so that the projectile clamping mechanism 8 slides along the gripper translation extension mechanism 7 under the drive of an external driving component. The external driving component can be a cylinder. The projectile clamping mechanism 8 and the gripper 9 can be connected by bolts and nuts.

[0024] like Figure 3 and Figure 4 As shown, the lifting device 6 includes a bracket 601, a servo motor 602, and a ball screw 603 arranged vertically. One end of the ball screw 603 is connected to the output end of the servo motor 602, and the other end is connected to the bracket 601 via a bearing. The servo motor 602 is fixed to the bracket 601. The translation device 5 is threadedly connected to the ball screw 603. When the servo motor 602 drives the ball screw 603 to rotate, the translation device 5 rises or falls along the ball screw 603.

[0025] The translation device 5 includes a funnel support 501 and a platform 502. The platform 502 is threadedly connected to the ball screw 603. A guide rail, a slider, and a cylinder are provided on the platform 502. The funnel support 501 has a connecting part 5011 and a funnel mounting part 5012. The connecting part 5011 has a guide rail connecting part and a cylinder connecting part. The guide rail connecting part is connected to the slider, and the cylinder connecting part is fixedly connected to the piston rod of the cylinder. The cylinder drives the funnel support 501 to slide along the guide rail. The funnel mounting part 5012 is U-shaped, with its two arms extending to the outer edge of the platform 502. A weighing device is installed on the funnel mounting part 5012.

[0026] The weighing device may be a pressure sensor 4. In some embodiments of the present invention, three pressure sensors 4 are provided, evenly distributed on the U-shaped funnel mounting portion 5012, thereby ensuring the accuracy of weighing. The present invention measures the injection amount of silicone rubber by a subtraction weighing method.

[0027] like Figure 5 As shown, the glue-dispensing funnel 3 device includes a funnel body 301 and a glue-dispensing port 302. The funnel body 301 is provided with multiple lugs 303, which are used to install the glue-dispensing funnel 3 onto the funnel support 501. After installation, the side wall of the glue-dispensing funnel 3 has three weighing contact points with the funnel support 501, and the glue-dispensing port 302 is located outside the edge of the platform 502. A pneumatically controlled programmable valve 10 is provided at the glue-dispensing port 302.

[0028] In some embodiments of the present invention, a funnel conveying device 11 is provided at the lifting device 6. The funnel conveying device 11 is provided with a clamping component for removing the glue-dispensing funnel 3 from the funnel support 501. A slide rail is provided at the bottom of the funnel conveying device 11 to transfer the removed glue-dispensing funnel 3 to the funnel replacement point for funnel replacement.

[0029] The working process of this invention:

[0030] After the projectile clamping mechanism 8 and the gripper 9 clamp and fix the projectile 2 in place, the silicone rubber-filled injection funnel 3 is installed on the translation device 5, and the lifting device 6 lifts the translation device 5 to a predetermined height. After reaching the predetermined height, the cylinder on the translation device 5 pushes the funnel bracket 501, causing the injection port 302 to move horizontally above the projectile.

[0031] When positive pressure is applied to injection funnel 3, the pneumatic control valve 10 is opened, allowing silicone rubber to flow into the projectile body. Pressure sensor 4 obtains the amount of silicone rubber injected into the projectile body by monitoring the weight of injection funnel 3 in real time. When the preset value is reached, the pneumatic control valve 10 closes. After injection funnel 3 moves away from the projectile body via translation device 5, clamp 9 is released, and projectile 2 leaves the injection device via conveyor line. A new projectile enters the injection device, and the above injection steps are repeated. When the silicone rubber in injection funnel 3 is completely injected, lifting device 6 descends to its lowest position, and funnel conveyor 11 transports injection funnel 3 to a replacement location.

[0032] This invention can automatically complete the entire glue injection process, effectively improving glue injection efficiency and the accuracy of glue injection amount. The overall structure of the device adopts a modular design, making replacement convenient and quick.

[0033] It should be noted that although the present invention has been described through the above embodiments, the present invention may have many other embodiments. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but these changes and modifications should all fall within the scope of protection of the appended claims and their equivalents.
