The utility model is intended to solve the above-mentioned defective that existing 03 formula rifle exists, and a kind of novel 03 formula rifle automatic machine is provided, and compressible casing length shortens the body of a gun, automatically step machine design more rationally, compactness and weight saving; Or keep the body of a gun constant, and increase barrel length relatively, can improve the bullet issuing velocity, thereby improve the performance of rifle.
The technical solution adopted in the utility model is as follows:
This technical scheme is the compressed technical scheme of a kind of 03 formula rifle automatic machine recoil stroke.There are counter motion in the piston component and the breech bolt assembly of 03 formula rifle automatic machine in emission process, between is set up a kind of constraint, limit the distance that it separates, make breech bolt assembly when entering unnecessary recoil stroke, be subjected to the added limitations of piston component, thereby reach the compressed purpose of recoil stroke.
This 03 formula rifle automatic machine comprises piston cylinder, piston rod, piston spring, breech housing, gunlock and kicker, described piston cylinder is communicated with rifle gun barrel top bleeding point, place the piston rod in the piston cylinder, put the piston spring between its front end piston plate and the set spring base of rifle gun barrel, promptly the piston spring is placed on the piston rod; Dress kicker in the breech housing spring eye, the kicker other end places on the spring base of rifle casing inwall; The built-in gunlock in gunlock hole of breech housing, the locking ear of gunlock front end radially outwardly projecting becomes the folding antithesis with the locking tooth of rifle gun barrel tail end.The characteristics of this automatic machine are: the spring eye bottom center of described breech housing has aperture becomes ladder hole, an elongated segment bar continues in the pushing face outside of described piston rod, extension rod is by this through hole, and the extension rod tail end is provided with the spacing stone roller of restriction breech housing recoil stroke.
The effect of the pushing face of described piston rod is constant, contacts with the location, outer face of described breech housing.
The spacing stone roller of the extension rod of described piston rod and tail end is in the column cavity of kicker and the action that is independent of each other.
When automatic rifle was launched, trigger was depressed, and hammer discharges the bump firing pin, and the bullet in the bore is pulled the trigger, and penetrates from gun barrel.After bullet was crossed bleeding point, the part powder gases was rushed in piston cylinder through bleeding point, promoted piston rod compression piston spring, pushed breech housing through piston rod pushing face and moved backward, and the motion of breech housing makes the gunlock rotation, and the locking up between handle and gun barrel is opened.After piston rod withdrawed from piston cylinder, the air pressure in the piston cylinder was released, and compressed piston spring begins push piston bar extension rod stop bit stone roller one and backwashes forward and reset; Breech housing and gunlock then under the bore residual voltage promotes with shell case recoil together, finish and depress hammer, ejection etc. while compressing kicker, when the spacing stone roller in collision piston rod rear end, breech housing spring eye bottom surface, the recoil stroke is defined by compression and puts in place, and breech housing moves after stopping to continue.And then under the recoil check spring effect, finish multiple to advance: push away newly springing into thorax, gunlock rotation locking and entire exercise such as wait to hit.
The characteristics of this programme are the recoil strength of the piston component in the automatic machine is used in order to offset the spacing later unnecessary recoil in breech bolt assembly recoil, shorten gunlock recoil total kilometres.Thereby under the rifle length of determining, the design length of casing can be shortened, make gunlock compactness, weight saving; Perhaps increase the length of gun barrel, the initial velocity of bullet is increased, strengthen lethality and improve accuracy, the body of a gun is more steady in the time of also can making shooting, improves the running fire hit rate.
