Description

TECHNICAL FIELD

[0001] The utility model belongs to weapon system technical field, concretely relates to a small -size ammunition air drop mechanism, and especially relates to a mechanism suitable for small -size ammunition air gravity drop, and the structure realizes the air gravity drop of small -size ammunition on the basis of portability, reliability, multi -platform adaptability. BACKGROUND

[0002] The ammunition is the core part in the weapon system, is launched to the target area by the help of the weapon (or other carrying platform), and is the final means of accomplishing the established battle task.

[0003] Small -size ammunition is favoured by the military of all countries in the world due to the characteristics of small size, light weight, mobile flexibility and low cost, and the main scene of modern war is generally urban warfare, special warfare and anti -inclined surface warfare, needs to consider the needs of ground weapon launching and air flight platform drop simultaneously, therefore, whether the small -size ammunition air drop can be realized on the basis of integrated design, makes the ammunition enter the combat area after being carried by the flight platform, and quickly executes the combat task after air drop, becomes the key factor of determining the combat effectiveness of small -size ammunition.

[0004] At present, the conventional air drop mechanism needs complex structure and electrical system, and has the problems of large mass, inconvenient installation, poor platform compatibility, complex operation process and long preparation time, which seriously restricts the combat effectiveness of small -size ammunition. Therefore, it is urgent to develop a small -size ammunition air drop mechanism which is simple to operate, light in weight and strong in adaptability. UTILITY MODEL CONTENTS

[0005] (1) technical problem to be solved

[0006] The utility model wants to solve the technical problem: how to provide a small -size ammunition air drop mechanism which is simple to operate, light in weight, reliable in mechanism actuation and can be applied to multiple platforms, and solve a series of problems such as long preparation time, large mass, complex operation process and the inability to adapt to multiple platforms of conventional air drop mechanism.

[0007] (2) technical scheme

[0008] In order to solve the above technical problems, the utility model provides a small -size ammunition air drop mechanism, the small -size ammunition air drop mechanism includes: bottom plate 1, holds ring seat 2, holds ring 3, pivot 4, latch 5, latch support 6, connecting rod 7, rudder 8, rocker arm 9, adaptive block 10;

[0009] The total assembly drawing of air drop mechanism (locking state) is as Figure 1As shown, the base plate 1 is reliably fixed to the flight platform with bolts. Based on the maximum operating conditions, the strength of the bolt connections is locally reinforced during the design phase to better ensure the reliable fixation of the base to the flight platform. Two bearing seats 2 serve as the main load-bearing components and are bolted to both ends of the base plate 1. The two sets of bearings 3 are of a split design, with a rotating shaft 4 passing through their mounting holes and mounted on the bearing seats 2. The rotating shaft 4 and the bearings 3 are fitted with a clearance fit to ensure that the bearings 3 can rotate along the rotating shaft 4. The pin 5 is inserted into another positioning hole of the retaining ring seat 2 and the retaining ring 3 to lock the retaining ring 3. To ensure that the pin 5 can be accurately positioned, the pin support 6 is installed on the base plate 1 by screws. The pin 5 is rotated through the positioning hole on it, so that the pin 5 can move intelligently along the axis. The pin has a "U-shaped" structure. Its other end is connected to the connecting rod 7 by a hinge. The other end of the connecting rod 7 is connected to the rocker arm 9 fixed on the servo motor 8 by a hinge. At this time, the servo motor 8 is in the locked state and is installed on the base plate 1 by screws. At this point, the entire airdrop mechanism is assembled.

[0010] The two clamping rings 3 are arranged in pairs to fit tightly against the outer wall of the ammunition, restricting the radial movement of the ammunition, while the friction force restricts the axial movement and rotation of the ammunition.

[0011] To ensure reliable fixing of the retaining ring 3, each retaining ring 3 passes through the positioning hole in the retaining ring seat 2 via a rotating shaft 4 and a pin 5. At the same time, to ensure the limiting accuracy of the pin 5, the pin 5 is guided by the pin support 6 before being inserted into the retaining ring 3. In this way, each retaining ring 3 is limited by two points, ensuring that the ammunition and the retaining ring 3 cannot move relative to each other, and realizing the locking function of the ammunition on the throwing mechanism.

[0012] The adapter block 10 is located inside the retaining ring 3 to adapt to different outer contours, and the friction coefficient can also be increased by the flexible adjustment pad.

[0013] Among them, such as Figure 2 The diagram shows the ammunition loading mechanism for the airdrop. When the flight platform arrives at the combat area to prepare for ammunition airdrop, the servo motor 8, under the influence of a control signal, rotates and drives the connecting rod 7 to move along the ammunition axis. The connecting rod 7 then pulls the pin 5 out of the locking hole of the retainer, releasing the retainer's limit. The ammunition falls under the influence of gravity, completing the airdrop. Figure 3 As shown.

[0014] The ammunition throwing function of the air-drop mechanism is driven by the steering engine 8, the swing arm 9 is rotated, and the two groups of connecting rods 7 simultaneously pull out the pins 5 from the two groups of embracing rings 3; the swing arm 9, the connecting rod 7 and the pin 5 are all connected by hinges; the synchronization of the two groups of embracing rings 3 is ensured, at this time, the embracing rings 3 are only constrained by the rotating shaft 4 after the pins 5 are pulled out, the ammunition simultaneously opens the two groups of embracing rings 3 along the rotating shaft 4 under the action of gravity, and is completely separated from the throwing mechanism, so that the throwing function of the ammunition is realized.

[0015] The multi-platform adaptation function of the air-drop mechanism is that: first, the main body for mechanism connection and force bearing is the bottom plate 1, a plurality of mounting holes are reserved on the bottom plate 1, and the bottom plate 1 is fastened with a plurality of flight platforms through bolts and nuts, and mechanical connection is convenient;

[0016] The air-drop mechanism is free of fireworks, is electrically driven by a single steering engine, and has strong electrical adaptability.

[0017] The air-drop mechanism is simple in structure, and is made of light and high-strength composite materials and aluminum alloy materials.

[0018] The bottom plate 1 is the main body for mechanism connection and force bearing, and is formed by winding Kevlar fiber composite materials, the material has high specific strength and light weight.

[0019] (Three) beneficial effects

[0020] Compared with the prior art, the air-drop mechanism is driven by a single steering engine, the ammunition is locked and thrown away, the consistency of the two groups of embracing rings is ensured, and the initial disturbance of the ammunition during throwing is greatly reduced. The air-drop mechanism has the advantages of light weight, simple structure, high separation reliability and strong platform adaptation capability, and can reliably throw various ammunition.
