Abstract

A machine gun buffer frame for a helicopter comprises a machine gun sliding beam. The machine gun sliding beam is provided with a pivoting end which is rotationally pivoted on the fixed plate and a rotating end which is driven to rotate by an angle; the machine gun seat comprises a sliding connecting sleeve and a machine gun fixing sleeve; the sliding connecting sleeve is connected with the machine gun sliding beam in an interference fit manner; the sliding lubricating mechanism is controlled to provide lubricating oil for the connecting surface of the machine gun sliding beam and the sliding connecting sleeve; the sliding lubricating mechanism provides lubricating oil for the connecting face of the machine gun sliding beam and the sliding connecting sleeve before the machine gun base slides in the length direction of the machine gun sliding beam and in the sliding process. By means of the sliding connecting sleeve and the machine gun sliding beam which are connected in the interference fit mode and the sliding lubricating mechanism used for lubricating the connecting face of the sliding connecting sleeve and the machine gun sliding beam, the problem that in a machine gun buffer frame for an airplane in the prior art, bolts and fixing holes used for fixing the machine gun base to the relative positions of the machine gun sliding beam are prone to damage can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of military aircraft gun rack equipment, in particular to a machine gun buffer rack for helicopters. Background technique [0002] Combat helicopters need to install machine guns at the position of the door during flight. Combatants can adjust the shooting position of the machine gun mount by adjusting the rotation angle of the machine gun mount and the telescopic length of the machine gun mount on the machine gun sliding beam, thereby providing combat personnel with Good shooting angles. But, because can produce bigger recoil force in the process of continuous shooting of machine gun, generally adopt bolt to fix the relative position of machine gun mount on the machine gun sliding beam in the prior art. The bolt and the fixing hole on the side of the machine gun sliding beam are easily deformed, which not only causes the position of the above-mentioned machine gun seat to be offset during the shooting proc...
