Description

Technical Field

[0001] The utility model relates to a bullet pressing machine, specifically a cam-type rapid bullet pressing machine, belonging to the field of military training equipment. Background Art

[0002] During the use of machine guns, bullet loading is a necessary preparatory work. However, in reality, there is no special bullet press for 12.7-mm machine gun bullets. Therefore, the bullet loading method is still manual hand pressing, which takes a lot of time, has low bullet pressing efficiency, and reduces the training efficiency. Moreover, when pressing bullets manually, the two ends of the ammunition belt are relatively sharp and can easily cause injuries to the hands of the bullet loading personnel, resulting in inconvenience in the daily training of the troops. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a bullet pressing machine that can improve the bullet pressing efficiency.

[0004] To solve the above technical problem, the cam-type bullet pressing machine provided by the utility model includes a cartridge belt driving assembly, a bullet pressing assembly, and a driving mechanism. Both the cartridge belt driving assembly and the bullet pressing assembly are connected to the driving mechanism.

[0005] The driving mechanism drives the bullet pressing assembly to reciprocate relative to the cartridge belt driving assembly, and drives the cartridge belt driving assembly to rotate through a synchronization assembly, and presses the bullets to be loaded into the cartridge belt.

[0006] In the utility model, the bullet pressing assembly includes a sliding assembly, a bullet pressing block, and a moving rod. The bullet pressing block is slidably installed on the sliding assembly. The moving rod is fixedly arranged at the lower part of the bullet pressing block. The moving rod is connected to the driving mechanism. The driving mechanism drives the bullet pressing block to reciprocate relative to the sliding assembly through the moving rod.

[0007] In the utility model, the driving device includes a transmission cylinder and a power handle. An equal-acceleration parabolic groove is arranged on the transmission cylinder. The lower part of the moving rod is located in the equal-acceleration parabolic groove. The power handle is fixedly connected to one side of the transmission cylinder. The driving mechanism is located on the side opposite to the cartridge belt driving assembly.

[0008] In the utility model, the synchronization assembly includes a ratchet and a synchronization pin. The synchronization pin is arranged on the transmission cylinder. The ratchet is fixedly connected to the cartridge belt driving assembly. The synchronization pin periodically drives the ratchet to rotate. When the synchronization pin drives the ratchet to rotate once, the cartridge belt moves a distance of one cartridge clip.

[0009] In the present utility model, the cam-type bullet loading machine further includes a bullet hopper, which is installed above the bullet loading assembly and is used to accommodate and sequentially discharge the bullets to be loaded. When the bullet loading assembly performs the bullet loading action, the upper part of the bullet loading assembly blocks the bullet discharging port at the lower part of the bullet hopper.

[0010] In the present utility model, shock-absorbing feet are further provided at the bottom of the bullet loading machine, and the shock-absorbing feet are used to reduce the vibration intensity during bullet loading.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the bullet hopper is used to accommodate and discharge machine gun bullets. The discharged machine gun bullets are pressed into the cartridge belt on the cartridge belt driving assembly by the bullet loading assembly, replacing manual bullet loading, improving the bullet loading efficiency, and avoiding the situation of the cartridge belt causing injury to the bullet loading personnel during manual bullet loading, with high safety;

[0013] 2. The slidable bullet loading assembly can perform reciprocating motion through the drive of the drive mechanism. By using the cooperation of the slider assembly and the bullet pressing block, the repeated motion of the bullet loading assembly is realized, ensuring the sustainable operation of the bullet loading machine and improving the bullet loading efficiency;

[0014] 3. The drive mechanism is used to provide power for the bullet loading assembly. The type of power can be manual cranking or an electric motor connected to the power handle, suitable for a variety of usage scenarios, with wide applicability;

[0015] 4. The synchronization assembly is used for the relative motion between the bullet loading assembly and the cartridge belt driving assembly, ensuring that the machine gun bullets can be sequentially pressed into the cartridges on the cartridge belt, avoiding the situation of missed pressing or repeated bullet loading;

[0016] 5. The shock-absorbing feet at the bottom of the bullet loading machine can reduce the vibration intensity during bullet loading and accelerate the bullet loading speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will describe in detail some embodiments of the present utility model with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0030] As Figure 1 、 2 As shown in FIGS. 1, 2, 3, and 4, in the first embodiment, a bullet pressing machine is provided. The bullet pressing machine is composed of an upper frame body 1 and a lower frame body 2. The upper frame body 1 and the lower frame body 2 are connected by screws. A bullet hopper 3 is welded on the upper frame body 1. The bullet hopper 3 is used to accommodate and discharge machine gun bullets. A slider assembly is fixedly arranged inside the upper frame body 1. A bullet pressing block 8 is slidably clamped on the sliding assembly 10 to perform reciprocating motion. A moving rod 9 that can move freely is arranged below the bullet pressing block 8.

[0031] The transmission cylinder 4, the bullet sprocket 7, and the ratchet 6 are installed on the lower frame body 2 through bearings. The bearings can reduce the resistance when the transmission cylinder 4, the bullet sprocket 7, and the ratchet 6 rotate, and improve the bullet pressing efficiency. The transmission cylinder 4 is installed on the side of the lower frame body 2 close to the ammunition loading personnel. The bearing structures at the ratchet 6 and the bullet sprocket 7 are the same as those at the bearing of the transmission cylinder 4. The bearings are arranged between the upper frame body 1 and the lower frame body 2 through the clamping seats 11 and are clamped and fixed by the upper frame body 1 and the lower frame body 2. An equal-acceleration parabolic groove is machined on the surface of the transmission cylinder 4. One end of the moving rod 9 extends into the equal-acceleration parabolic groove. When the ammunition loading personnel rotate the power handle 5 to drive the transmission cylinder 4 to rotate, the moving rod 9 is driven by the groove to perform linear reciprocating motion, thereby realizing the bullet pressing action. The ratchet 6 and the bullet sprocket 7 are connected by a flat key and are installed on the side of the lower frame body 2 opposite to the power handle 5, ensuring the safety of the ammunition loading personnel. The ratchet 6 and the bullet sprocket 7 have the same number of teeth and rotate synchronously. The ratchet 6 is driven to rotate by the synchronizing pin 12 on the transmission cylinder 4. While the transmission cylinder 4 drives the bullet pressing block 8 to move, it also drives the ratchet 6 to move, and further drives the bullet sprocket 7 and the bullet chain on the bullet sprocket 7 to move, ensuring that the entire bullet pressing process can proceed smoothly.

[0032] A shock-absorbing foot is also arranged at the bottom of the lower frame body 2 to reduce the vibration intensity of the machine body during bullet pressing.

[0033] When the first embodiment is actually used, place the ammunition press steadily, put 12.7mm bullets into the ammunition hopper 3 in a certain direction, then connect the ammunition belt to the ammunition sprocket wheel 7, rotate the power handle 5 for one week, and the transmission cylinder 4 drives the moving rod 9 and the ammunition pressing block 8 to make a linear reciprocating motion along the sliding assembly 10. During this process, the bullets complete the entire ammunition pressing action of falling from the ammunition hopper 3 into the ammunition belt and being pushed into the ammunition belt by the ammunition pressing block 8. When performing the ammunition pressing action, the ammunition discharging port at the bottom of the ammunition hopper 3 is blocked by the upper part of the ammunition pressing block 8 to prevent the bullets in the ammunition hopper 3 from falling out and there is no time to perform ammunition pressing; after completion, the synchronizing pin 12 drives the ratchet wheel 6 to rotate by a small angle, and the ratchet wheel 6 drives the ammunition sprocket wheel 7 to rotate synchronously through a flat key, and rotates the next empty ammunition clip to the ammunition pressing position. Thus, the entire ammunition pressing action of the ammunition press is completed. Continuously repeating the above operations can complete the ammunition pressing action of the entire ammunition belt. Compared with manual ammunition pressing, the ammunition pressing speed is fast, the intensity of ammunition pressing is low, and the ammunition pressing efficiency is improved.

[0034] The difference between the second embodiment and the first embodiment is that a motor is connected to the power handle 5, and the motor is used to drive the power handle 5 to rotate, further reducing the working pressure of the ammunition pressing personnel and improving the ammunition pressing efficiency.

[0035] In the above description, many specific details are elaborated to fully understand the present invention. However, the above examples are only the preferred implementation modes of the present invention and cannot be used to limit the scope of the rights of the present invention. Simple modifications and equivalent changes made to the above examples based on the essence of the present invention still fall within the scope of the present invention.
