Description

Technical Field

[0002] The barrel, as a thick-walled hollow tube, is the most basic and important part of the gun body. Its main function is to give the bullet a certain direction and initial velocity. It is also an important guarantee for reliable accuracy. Therefore, during the manufacturing process of firearms, the strict structural dimensions and sufficient strength of the barrel must be ensured to meet the requirements of barrel use. However, due to various factors, there are various hidden dangers that cause barrel damage. In the mildest case, it causes cracks and expansion deformation of the barrel, and in the worst case, it causes barrel explosion. When the above situation occurs during shooting, it will cause the gun to be destroyed and people to die. In order to ensure the safety of firearms during use and avoid barrel damage, each barrel must be tested for strength with a high-pressure bullet whose average maximum chamber pressure is higher than the conventional bullet used in the firearm before leaving the factory.

[0003] At present, conventional detection is carried out through simple devices, specifically manually knocking the bottom of the firing pin to trigger the bullet primer to achieve the shooting of high-pressure bullets. This method has low safety during implementation, many operating points, and is prone to mistakes, causing irreparable damage; operators need to work in a high-noise, high-exhaust environment for a long time, which is harmful to the human body.

[0026] The firing rod is inserted into the recoil spring and placed in the connecting transition sleeve. The front end of the firing extension rod contacts the rear end of the firing pin. The rear end of the firing extension rod is interference fit with the circular ring sleeve at the front end of the firing rod. The rear end of the firing rod has threads and is connected to the locking screw sleeve and the locking nut.

[0028] like Figure 3 The clamping and lifting module 3 shown includes a height-lifting cylinder 20, a horizontal clamping cylinder 17, a clamping claw U-shaped slide rail seat 18, an L-shaped clamping claw 19, and a lifting connection block 25. The height-lifting cylinder 20 is mounted on the side plate 27 of the T-shaped base, and the bottom end of the lifting connection block 25 is connected to the piston rod of the height-lifting cylinder 20 through a slot, and the other end face is mounted on the Z-shaped movable fixed block 24.

Two reinforcing ribs are connected to the base 28 on one side and to the side plate 27 on the other side.

[0030] The firing process of the present invention:

[0031] First, the barrel chamber end enters the firing sleeve 7 of the connection module under the action of the equipment lifting mechanism to complete the locking. After the locking is completed, the horizontal clamping cylinder 17 (servo cylinder) drives the L-shaped clamp 19 (clamping pliers) to open automatically, and the height lifting cylinder 20 (servo cylinder) begins to descend. When it descends to the top of the firing rod 14, the horizontal clamping cylinder 17 automatically shrinks, and the L-shaped clamp 19 automatically closes, clamping the upper ear shaft (positioning plate) of the locking screw sleeve 15. The height lifting cylinder 20 drives the horizontal clamping cylinder 17 to move to the specified position in the positive direction of the Y axis. Since one end of the lifting connection block 25 is connected to the horizontal clamping cylinder 17 and the other end is connected to the auxiliary support module 4, the height lifting cylinder 20 will synchronously drive the auxiliary support module 4 to move in the positive direction of the Y axis, and the slot of the positioning U-shaped slide rail seat 23 in the auxiliary support module 4 is stuck in the Y-axis moving slide rail 21 to ensure the stability of the movement process. After reaching the designated position, the pressure contact block 22 on the Z-shaped movable fixed block 24 will contact the flexible movable pulley 29 of the position detection module 5. At the same time, when the height lifting cylinder 20 drives the horizontal clamping cylinder 17, the recoil spring 12 on the firing rod 14 will be synchronously compressed and tightened in the process of moving in the positive direction of the Y axis, so that the entire firing rod 14 is in a stressed state. After the pressure contact block 20 contacts the flexible movable pulley 29 of the position detection module 5, the horizontal clamping cylinder 17 is released, the firing rod 14 is in a free state, and the firing rod 14 in the connecting sleeve 13 moves rapidly in the negative direction of the Y axis under the drive of the spring force of the recoil spring 12, and the firing extension rod 11 hits the firing pin 10 installed in the firing sleeve 7, and the firing pin 10 fires downward, passes through the center of the firing sleeve 7, and hits the bullet primer in the barrel chamber, completing the firing of the high-pressure bullet. In the process of the firing extension rod 11 hitting the firing pin 10, since the firing pin spring 9 is mounted on the firing pin, the firing pin spring 9 will be compressed synchronously. When the firing pin 10 hits the bullet primer, the return spring 12 is just in a free state (without spring force), and the firing pin spring is compressed to the shortest and releases the spring force instantly, driving the firing pin 10 to move upward.

[0032] The present invention has a simple structure, low difficulty in parts processing, and convenient assembly, and can realize the automatic firing of high-pressure bullets, freeing personnel from high noise and harmful gases, realizing the separation of man and machine, greatly improving shooting efficiency, reducing shooting risks to the greatest extent, and reducing manual labor intensity.

Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
