Description

Technical Field

[0001] The invention belongs to the technical field of ammunition processing equipment, and in particular relates to a gunpowder chamber decomposition device. Background Art

[0002] With the continuous development of military technology, the gunpowder chamber plays a vital role in military equipment. However, after the gunpowder chamber is used, how to safely and effectively decompose it has always been a problem that has plagued the relevant fields. In the prior art, the decomposition of the upper plunger of the gunpowder chamber is often carried out by simple manual operation. Generally, a punch is used to align the fixing pins that fix the upper plunger and the lower plunger on the gunpowder chamber, and a hammer is used to hit the punch to loosen the two fixing pins, and then the punch is used to punch it out. After removing the fixing pin, use the punch and hammer to hit the upper plunger downward until it is against the lower plunger, and then force the lower plunger out of the gunpowder chamber; insert a punch into the air valve hole to support the upper plug, and use a hammer to knock the upper plug out of the gunpowder chamber. This traditional method uses a punch and a hammer to knock, and it is easy to scratch the gunpowder chamber and the upper plunger during the punching process. It is not only inefficient and easy to cause product damage, but also has a high safety risk. Therefore, developing a device that can efficiently and safely decompose the gunpowder chamber has great practical significance and application value. Summary of the invention

[0003] In view of the above-mentioned defects, the present invention aims to provide a gunpowder cartridge chamber decomposition device. The device ensures the high efficiency of the decomposition of the plunger on the gunpowder cartridge chamber through auxiliary devices such as a clamping mechanism and a fixing mechanism, while also avoiding scratching the surface of the gunpowder cartridge chamber, thereby ensuring the safety of the decomposition process.

[0004] In order to achieve the above technical objectives, the following technical solutions are adopted: A gunpowder chamber decomposition device comprises a clamping mechanism, a positioning mechanism, a separating mechanism and a fixing pin; the clamping mechanism is a frame-shaped structure with an open front end, used for clamping the gunpowder chamber; the fixing pin is located at the front end of the clamping mechanism and is vertically inserted into the top of the clamping mechanism, used for limiting the displacement of the gunpowder chamber; the positioning mechanism is located in the middle of the clamping mechanism, used for fixing the upper plunger, and comprises a positioning block and a positioning pin; a through hole is axially provided in the middle of the positioning block for the upper plunger to pass through, and two vertically arranged positioning holes are radially provided at the front end of the positioning block for the positioning pin to be inserted; the separating mechanism comprises a connecting block and a lifting screw, the front end of the connecting block is fixedly connected to the rear end of the positioning block, and the rear end is axially provided with a blind hole, and the lifting screw thread passes through the rear end wall plate of the clamping mechanism and falls into the blind hole.

[0005] Furthermore, the clamping mechanism is a frame-type structure consisting of a front cover plate, a rear cover plate, a bottom plate, a left wall plate, a right wall plate and a rear wall plate; the left wall plate and the right wall plate are vertically symmetrically arranged, and the tops of the two are fixedly connected to the front end of the front cover plate, the rear end of the front cover plate is fixedly connected to the front end of the rear cover plate, the rear end of the rear cover plate is fixedly connected to the top of the rear wall plate, the bottom of the rear wall plate is fixedly connected to the rear end of the bottom plate, and the front end of the bottom plate is fixedly connected to the bottom of the left wall plate and the bottom of the right wall plate.

[0006] Furthermore, the bottom plate and the front cover plate are respectively provided with U-shaped notches at the front end for clamping the powder chamber; the left wall plate and the right wall plate are respectively provided with openings for placing the positioning block and the connecting block.

[0007] Furthermore, the two positioning holes at the front end of the positioning block are staggered and arranged vertically, and two screws are radially arranged in parallel at the rear end for threaded connection with the front end of the connecting block.

[0008] Furthermore, a groove is provided at the rear end of the positioning block for accommodating the connecting block.

[0009] Furthermore, the positioning block is composed of two symmetrically separated T-shaped blocks, and a positioning pin is inserted into the positioning hole to connect the symmetrically separated positioning blocks and limit the displacement of the upper plunger in the up and down directions.

[0010] Furthermore, an operating rod is radially inserted into the head of the lifting screw to facilitate the rotation of the lifting screw.

[0011] Furthermore, the front end of the lifting screw is a smooth cylinder with a diameter smaller than the outer thread of the rear end, and the front end smooth cylinder falls into the blind hole of the connecting block.

[0012] Furthermore, a round ball is welded to the front end of the lifting screw rod, and the round ball falls into the blind hole to clamp the connecting block and the lifting screw rod.

[0013] Furthermore, after the front end of the lifting screw is assembled with the connecting block, spot welding is performed at the opening of the blind hole to prevent the lifting screw from falling off.

[0014] The beneficial effects achieved by the present invention are: Compared with the prior art, the present invention utilizes a clamping mechanism to place the powder chamber, and by inserting a fixing pin at the front end of the clamping mechanism, the displacement of the powder chamber is limited, thereby ensuring that the powder chamber remains stable in the clamping mechanism. The upper plunger of the powder chamber passes through the through hole on the positioning block in the fixing device, and then the upper plunger is fixed by limiting the up and down displacement of the upper plunger through the positioning pin to prevent the upper plunger from shaking or moving during the disassembly process. The rear wall plate of the clamping mechanism is threadedly connected by a lifting screw rod, and finally fixed in the blind hole of the fixing block, ensuring that the lifting screw rod, the fixing block and the positioning block complete the disassembly work synchronously. Rotate the lifting screw rod to convert the rotational motion into linear motion, and gradually disassemble the upper plunger from the powder chamber. The device can realize efficient and safe disassembly of the upper plunger of the powder chamber. The present invention adopts multiple stable protection measures to ensure the safety of the decomposition process and effectively reduce the safety risks; the disengagement of the bayonet of the gunpowder cartridge chamber is an effective provision made in advance. The present invention uses a punch and a hammer to accurately strike the upper plunger by presetting a threaded hole on the rear wall plate of the clamping mechanism, thereby avoiding the wear on the surface of the gunpowder cartridge chamber caused by the disengagement of the fixed bayonet in the traditional method; the device is easy to operate, and the upper plunger can be separated from the gunpowder cartridge chamber by rotating the lifting screw, thereby improving work efficiency.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0022] like Figure 1-3 As shown, a gunpowder chamber decomposition device of the present invention comprises a clamping mechanism, a positioning mechanism, a separation mechanism and a fixing pin 1.

[0023] The clamping mechanism is a frame structure consisting of a front cover plate 2, a rear cover plate 3, a bottom plate 8, a left wall plate 10, a right wall plate 11 and a rear wall plate 6; the left wall plate 10 and the right wall plate 11 are vertically symmetrically arranged, and the tops of the two are fixedly connected to the front end of the front cover plate 2, the rear end of the front cover plate 2 is fixedly connected to the front end of the rear cover plate 3, the rear end of the rear cover plate 3 is fixedly connected to the top of the rear wall plate 6, the bottom of the rear wall plate 6 is fixedly connected to the rear end of the bottom plate 8, and the front end of the bottom plate 8 is fixedly connected to the bottom of the left wall plate 10 and the bottom of the right wall plate 11. The front end opening of the clamping mechanism is used to place the gunpowder chamber, and U-shaped notches are respectively provided at the front ends of the bottom plate 8 and the front cover plate 2 for convenient clamping of the gunpowder chamber; the left wall plate 10 and the right wall plate 11 are respectively provided with openings for placing the positioning block 4 and the connecting block 5; the fixing pin 1 is located at the rear end of the U-shaped notch of the front cover plate 2 and is vertically inserted into the front cover plate 2 for limiting the displacement of the gunpowder chamber, and the fixing pin 1 and the clamping mechanism jointly fix the gunpowder chamber.

[0024] The positioning mechanism includes a positioning block 4 and a positioning pin 9, which are located at the openings of the left wall plate 10 and the right wall plate 11 of the clamping mechanism; the positioning block 4 is two T-shaped blocks symmetrically separated, and a through hole 41 for the upper plunger to pass through is axially arranged in the middle; two vertically staggered positioning holes 42 are radially arranged at the front end of the positioning block 4, and the positioning holes 42 are used to insert the positioning pin 9, and the positioning pin 9 connects the two symmetrically separated positioning blocks 4 and limits the displacement of the upper plunger in the up and down directions; a groove is provided at the rear end of the positioning block 4 for accommodating the separation mechanism, and two screws are radially arranged in parallel at the rear end for fixing and connecting the separation structure.

[0025] The separation mechanism includes a connecting block 5 and a lifting screw 7.
