Fuze rotary demounting device for small-caliber aircraft projectiles

Abstract

The invention relates to a fuze rotary demounting device for small-caliber aircraft projectiles and belongs to an automatic demounting line for the small-caliber aircraft projectiles. The fuze rotary demounting device comprises a rotary demounting power head, a projectile positioning clamping mechanism, a positioning lifting slide table, a fuze-moving-out mechanical arm, a counter weight mechanism and a rack. A hydraulic floating jaw and a spring seat are used for solve the key technical problem of fuze streamline conical surface clamping, reliable projectile positioning is guaranteed by the shape-following design of the cartridge jaw, and safe and reliable operation of the device is guaranteed by the clamping force for hydraulic clamping a fuze and a battle part. A rotary demounting separating end falls by the aid of the axial force and self weight, rotary demounting is performed according to screw pitch, and disordered fastening is avoided. By the fuze rotary demounting device, safe, fast and automatic fuze rotary demounting is achieved through electric, gas and liquid linkage control, automatic demounting of the small-caliber aircraft projectiles is achieved, and good technical support is provided for retired ammunition demounting.

Description

technical field The invention belongs to the technical field of automatic disassembly of decommissioned ammunition, and is particularly suitable for the safe automatic disassembly of fuzes of small-caliber artillery shells. Background technique Due to inventory pressure, environmental protection requirements and safety considerations, the dismantling, destruction and utilization of decommissioned ammunition is an urgent problem to be solved by the military. The invention is a fuze unscrewing device developed for the disassembly of small-caliber shells. The disassembly of small-caliber shells is generally divided into steps such as primer removal, fuze removal, separation of cartridge and combat part, propellant pouring and collection, among which fuze removal is the most important step in the disassembly process, which is directly related to disassembly. sub-process security. Usually, the fuze of the small-caliber projectile and the warhead are connected by threads, and th...

AI Technical Summary

Problems solved by technology

Usually, the fuze of the small-caliber projectile and the warhead are connected by threads, and the disassembly method basically adopts the unscrewing method. Since the shape of the fuze is mostly conical and streamlined, it brings great difficulties to its automatic unscrewing. No fuze automatic splitting device
