The sprocket and the directive wheel are fixedly connected with the shaft, the cylindrical cam is sheathed on the shaft in an empty mode, and a bullet pulling wheel and a bullet storing bin which are synchronized with the directive wheel are arranged above the directive wheel. The utility model has the advantages of labor-saving loading and high efficiency.

Description

Hand power loading machine for sprocket of machine guns

A kind of machine gun ammunition belt hand power loading machine.

Machine gun is one of main automatic weapon of infantry.Machine gun generally adopts Ammunition Belt Links Feed, and said ammunition belt is actually a kind of anchor clamps, becomes long-chain by the spring plate group of being with opening, can clamp bullet singly.Bundle suppresses the spring clip on the ammunition belt, generally by hand or mechanical means.The manual bullet of pressing is required great effort very much, hinder hand easily, and efficient is low, and known machinery presses the bullet mode to be, adopts a kind of device that bullet is forced to be pressed into from the spring leaf opening of ammunition belt sidewards, the shortcoming that shoots in this way is, press when playing and require great effort very much, the spring leaf of easy damaged ammunition belt can not accurately be pressed onto bullet and give allocation, continuous ammunition feed to machine gun can cause adverse effect, has to manually proofreading and correct.Therefore army seldom uses.

The purpose of this utility model is to provide a kind of mechanical ramming arrangement that can overcome above-mentioned shortcoming, and said device shoots laborsaving, the efficient height, and bullet can accurately be located, and fool proof.

For achieving the above object, scheme of the present utility model is: an axle is set, on same axis at least by axial location arrange in regular turn one with the sprocket wheel of ammunition belt engagement, a directive wheel and a garden post cam, the peripheral five equilibrium of directive wheel has the groove that conforms to bomb body, groove is identical with the sprocket indentations number and direction is consistent, so that the bullet of bullet can freely enter the spring leaf opening of ammunition belt, simultaneously the bomb body groove that falls into directive wheel is as pack into the location of giving before the ammunition belt of bullet.Said sprocket wheel and directive wheel and axle are affixed, and the centre bore of garden post cam and the empty cover of axle are so when the axle that is connected with sprocket wheel and directive wheel rotated with power set, garden post cam was relative to not rotating.Said power set can be used manually, also can be motor-driven.The cam curve of garden post cam is a helix, the limit of cam props up the flange outer sides of projectile tail, do not contact the recessed fire in a stove before fuel is added device of projectile tail, when the axle that connects sprocket wheel and directive wheel rotates, the bullet that has given the location is propped up by cam curve, make bullet along its axially-movable, the bullet body is pressed into the spring clip of ammunition belt.Press bullet to carry out continuously for making, be provided with the storage magazine and dial the bullet device.

The storage magazine is a box describe device, following dividing plate jaggy is equipped with in the centre, with the magazine separated into two parts, wherein Yi Bufen sidewall paneling has axis hole, the bullet of dialling of tape spool can be installed takes turns, the following bulkhead that aim to dial plays wheel location has breach, and breach is relative with T v notch v on the garden tube that contains sprocket wheel etc., storage magazine and the connection of garden tube hinge.

The peripheral five equilibrium of dialling the bullet wheel has the garden connected in star, and the groove number is identical with directive wheel groove number, and identical with the directive wheel rotating speed, for reaching synchronous rotation, at group bullet wheel shaft and guide wheel shaft an equal-sized belt pulley is set respectively, by the cross(ed) belt transmission.

Now this programme is further described by embodiment.

Present embodiment is applicable to the 67-2 type general purpose machine gun ammunition belt pressure bullet that the up-to-date equipment of the Chinese People's Liberation Army uses, and bullet that this equipment is used and ammunition belt are as shown in Figure 3.Complex chart 1-Fig. 5 description architecture is as follows:

One sprocket wheel (21) and directive wheel (20) are set in the garden tube (7), axle (9) is for linking the rotating shaft of sprocket wheel (21) and directive wheel (20), be weight reduction, sprocket wheel of present embodiment (21) and directive wheel (20) hollow out in the middle of adopting, again immovable fitting together, as shown in Figure 2, the uniform garden connected in star that conforms to bomb body of directive wheel (20) periphery, the groove number is identical with the sprocket wheel number, and direction and position consistency.As shown in Figure 5.Axle (9) is supported by the axis hole on end cap (8) and (16), and the flange of two end cap is also located and affixed garden tube (7) simultaneously, and the end cap (16) of close locating wheel one side also is a garden post cam simultaneously, and cam curve is

Revolve line, as shown in Figure 5,

The operator shakes handle (17) with the hand clockwise direction and can rotate by drive sprocket, and the ammunition belt (11) that sprocket wheel rotation drive is engaged with is sent constantly into; Magazine (3) is housed on garden tube (7), the bullet of dialling wheel (12) is arranged in the magazine, it is identical with teeth number of sprocket to dial the bullet wheel, the right axle head of sprocket wheel drives group bullet wheel (12) rotation by the adhesive tape (14) of two belt pulleys of equal and opposite in direction (15) and (22) and intersection transmission, keep between the two rotating synchronously, as shown in Figure 2.Bullet is put into magazine (3), makes the bullet head and the tail consistent.Magazine (3) is divided into two parts with dividing plate (23), axle sleeve (10) is housed on the compartment wallboard, the bullet wheel (12) of dialling that axle (13) is housed is sent bullet into sprocket wheel successively, the bullet warhead section is freely dropped into cartridge clip from the elastic opening of cartridge clip, body partly enters the directive wheel groove and obtains pre-determined bit simultaneously, when sprocket wheel drives ammunition belt ceaselessly relative to cam (16) when rotating, bullet along the rising of cam spiral end face and be pushed into cartridge clip, and reaches the precalculated position with regard to one by one.

Can find out that from present embodiment this slide feeding device is simple in structure, can finish continuous pressure bullet process by rotatablely moving of sprocket wheel, because the garden of employing post cam mechanism, bullet is done axially-movable, only need overcome the frictional force between cartridge clip and the bullet body, therefore, the thrust that bullet is pushed cartridge clip is very little, be 19 newton as calculated, and the turning moment of sprocket wheel only is 1.9 Newton meters, operates very light, because the cam mechanism working stability is reliable, so the bullet location accurately.In pressing the bullet process, because lateral margin contacts with cam working face bottom the bullet, to greatest extent away from fire in a stove before fuel is added position, so press the bullet process to be perfectly safe.

Directive wheel in the present embodiment is dialled available metal such as bullet wheel or nylon or other engineering plastics and is made.

Other label of present embodiment is: (1) is caisson, (2) bullet; (4) cover plate (5) is worn pin, (6) spring leaf (18) Handle axis, (19) handle sleeve.
