Abstract

The invention discloses a gun rack balancer press fitting method and belongs to the technical field of firearm assembly. The method comprises the following steps that: a, the outer tube of a balanceris put into the outer tube fixing seat of a gun rack balancer press-fitting machine, a set screw is screwed, an inner balance spring and a balance spring are sequentially put into the inner hole of the outer tube of the balancer, and a guide cylinder is sleeved with the outer tube of the balancer; b, the inner tube of the balancer is put into the guide cylinder, is sleeved with the inner balance spring and the balance spring, the upper end of the inner tube of the balancer sleeved with an inner tube sleeve, the axial direction of a roller is adjusted, so that the roller can press a pressing rod connected with the inner tube sleeve; c, the inner tube sleeve is continuously pressed, after the inner tube of the balancer and the outer tube of the balancer are perpendicular to each other, pressing and rotation actions are stopped; and d, the pressing rod is lifted upwards, a balancer assembly part is taken out, and an assembly action is completed. With the method adopted, in an actual assembling process, operation is quite simple, time and labor are saved, safety and reliability are achieved, assembling efficiency and assembling quality can be effectively improved, and tool manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of firearm assembly, in particular to a method for press-fitting a gun frame balancer. Background technique [0002] As there are more and more types of large-caliber machine guns, the gun mounts and balancers they are equipped with are more and more widely used. Widely used in combat vehicles, warships, fighters and other combat platforms. The gun rack balancer is composed of an inner tube, a balance spring, an inner balance spring and an outer tube part. The balance spring and the inner balance spring are assembled in the inner and outer tubes, and the outer circular tenon of the inner tube is interlocked with the tenon in the inner hole of the outer tube. [0003] When assembling the balancer parts, the worker first clamps the outer tube part of the balancer on the vise. The clamping requirements are very reliable, and a little looseness may easily cause safety accidents. Then put the inner balance sp...
