Ammunition attitude corrector

technical field

The invention belongs to the technical field of ammunition correction, and in particular relates to an ammunition attitude corrector.

Background technique

Loading magazines is one of the important contents of pre-war preparations. Our army used to equip rifles with simple loading devices. However, due to the disordered order of ammunition during use, manual corrections were required, which made the loading efficiency low and easy. Injured hands have been gradually eliminated. At present, our army uses manual loading of magazines. Manual loading has disadvantages such as long loading time, large manpower consumption, and high physical exertion, which seriously restricts the overall combat efficiency. In order to shorten the loading time, reduce the input of manpower, and maintain the physical strength of the personnel, on the basis of studying the characteristics of our army's bullets, clip structure, and application characteristics, an ammunition attitude corrector is urgently needed to overcome the above problems.

The correction tongue is corrected and discharged from the discharge port at the lower part of the hopper.

Further, the shrapnel fetching includes a vertical plate arranged vertically at the lower part of the hopper and movably connected with the hopper. A horizontal plate is constructed on the upper end of the vertical plate. When the shrapnel fetching is driven by the correction tongue to move to the highest point, the The gap between the horizontal plate and the inner wall of the hopper can allow a piece of ammunition to pass through. When the position of the shrapnel is lower than the highest point of its movement, the gap between the horizontal plate and the inner wall of the hopper is smaller than the diameter of the ammunition.

Further, splints are provided on both sides of the riser, each splint is detachably connected to the inner wall of the hopper, and the riser is movably assembled in the gap between the splint and the hopper.

Further, the driving part includes a servo motor installed on a fixed frame and its output end is coaxially equipped with a driving gear, and a driven gear meshed with the driving gear is rotatably connected to the fixed frame, and the driven gear and Correct tongue eccentric articulation.

Further, a connecting pin is constructed at the eccentric position of one end face of the driven gear, and a bar-shaped hole perpendicular to its moving direction is opened on the correction tongue, and the connecting pin extends into the bar-shaped hole, The fixing bracket is constructed with two oppositely arranged limiting plates, and the part of the correction tongue outside the hopper is located between the two limiting plates.

Further, the radius of the driving gear is smaller than the radius of the driven gear.

It is discharged from the discharge port 204 provided at the lower part of the hopper 200. The working principle and advantages of the present invention are: the hopper 200 of the present invention is used to hold ammunition, the correction mechanism 300 is used to correct the ammunition in the hopper 200 one by one, and the corrected ammunition is discharged out of the hopper 200 through the outlet 204 one by one; Specifically, the driving part drives the straightening tongue 308 connected to it to reciprocate at the lower part of the hopper 200. During this process, the spring piece 202 is driven to reciprocate in the vertical direction by the straightening tongue 308. In this way, the spring piece 202 is taken out. One piece of ammunition is taken out in one reciprocating movement, and the shrapnel 202 is taken out from the hopper 200, and the top pressure of the end of the straightening tongue 308 makes the ammunition straightened at the discharge port 204, and falls into the rack mounted below it. In the receiver 400 on 100; in summary, the present invention improves the efficiency of ammunition correction, reduces the defects caused by manual operation, improves the safety performance of correction operations, and provides convenience for subsequent ammunition filling and other operations.

As a preferred embodiment of the present invention, as shown in FIG. 3, the shrapnel 202 includes a vertical plate vertically arranged at the bottom of the hopper 200, the vertical plate is movably connected with the hopper 200, and a horizontal plate is constructed on the upper end of the vertical plate. When the shrapnel 202 is driven by the correction tongue 308 and moves to the highest point, the gap between the horizontal plate and the inner wall of the hopper 200 can allow an ammunition to pass through. When the position of the shrapnel 202 is lower than the highest point of its movement, the horizontal plate and The gap between the inner walls of the hopper 200 is smaller than the ammunition diameter. Specifically, the above-mentioned notch is arranged on the vertical plate. As shown in FIG. One end of the positioning plate 311 protrudes from the corresponding end of the correction tongue 308, and when the notch of the elastic sheet 202 is in contact with the upper positioning plate 310, the end of the upper positioning plate 310 entering the notch is configured as a slope, so that the upper The positioning plate 310 enters the notch smoothly, and gradually lifts up the shrapnel 202. When the highest upper end surface of the upper positioning plate 310 contacts the notch, the horizontal plate moves upward to the highest point and the gap between the inner wall of the hopper 200 is just right. For a piece of ammunition to pass through; when the notch of the shrapnel 202 is in contact with the lower positioning plate 311, the end of the lower positioning plate 311 entering the notch is configured as a slope, and its function is the same as the slope of the upper positioning plate 310, and the positioning plate 202 is positioned at the bottom The top pressure of the plate 311 moves downward, so that only one piece of ammunition can be taken at a time. In the above two processes, one of the upper positioning plate 310 and the lower positioning plate 311 acts on the shell piece 202 through the slot instead of Both act on the notch at the same time or not, that is, the upper positioning plate 310 and the lower positioning plate 311 are in the state of acting on the notch alternately. When the second reciprocating movement starts, that is, during the extension of the correction tongue 308, the protruding end of the correction tongue 308 cooperates with the discharge port 204 to correct the ammunition and discharge it from the hopper 200, and the next ammunition is taken by the shrapnel 202 at the same time.
