A portable primer removal tool

Abstract

A portable primer disassembling tool comprises a pressure exerting device, a base plate and face plates, wherein the base plate and the face plates are each in a flat plate shape; the face plates are piled on the base plate and relatively fixed, a plate closing locking device is fixedly installed on the periphery of the base plate, and the pressure exerting device is installed above the face plates; a driven shaft, a compressed spring sleeve and a pressing nut are installed on the pressure exerting device, a shift claw corresponding to a primer installation groove in position is installed at the bottom of the driven shaft, and the driven shaft is installed in the compressed spring sleeve; the lower portion of the driven shaft penetrates through the face plates and the base plate, the upper portion of the driven shaft penetrates out of the compressed spring sleeve, and a compressed spring sleeving the driven shaft is installed between a convex shoulder in the compressed spring sleeve and the top face of the compressed spring sleeve; and a large gear is installed outside the driven shaft in the base plate and the face plates in a sleeving mode, and transmission occurs between the driven shaft and the large gear through a transmission key. The portable primer disassembling tool is small in size and light in weight and achieves rotating motion and axial movement of a rotating disassembling part, and effective clamping for a closing plate is ensured, so that cannon primers are safe and convenient to disassemble.

Description

technical field [0001] The invention relates to shell dismantling technology, in particular to a portable primer dismantling tool. Background technique [0002] If the faulty projectiles in the shooting range or in the field fail to be transported back to the rear base for processing, they cannot be transported and installed in time. After waiting for accumulation, the transport will be difficult to store and there will be safety hazards. The use of portable dismantling tools can solve safety and transportation problems in a timely and convenient manner, but the movable dismantling tools in the prior art are still relatively large in size and weight, and are inconvenient to carry. [0003] The primer of the shell is located at the bottom of the shell, which is relatively sensitive, and there is a danger of triggering an explosion when it is hit, and the installation is firm. The bottom of the cartridge case is provided with a primer sealing plate integrated with the cartrid...

AI Technical Summary

Problems solved by technology

Removing the primer not only needs to fix the cartridge case and rotate the primer part with sufficient torque, but also because the primer is installed firmly, it is easy to cause the tool to slip out of the primer installation groove when rotating the primer, so it is necessary to exert sufficient pressure on the tool during removal to prevent it from slipping out of the primer installation groove However, during the disassembly process of the primer along the thread, there is also an outward translational movement along the axis, and the simple rotation and disassembly of the fixed position cannot remove the primer.

Due to the problems of projectile body fixing, complex equipment, insufficient power and potential safety hazards in the dismantling of shells and primers, excessive force in manual dismantling poses serious safety hazards, so generally only large-scale special safety dismantling equipment can be used
