Abstract

The invention discloses a method for press-fitting a gun rack balancer, which belongs to the technical field of firearm assembly, and is characterized in that it comprises the following steps: a. Putting the outer tube of the balancer into the outer tube fixing seat of the gun rack balancer press-fitting machine, Tighten the set screws, put the inner balance spring and the balance spring into the inner hole of the balancer outer tube in turn, and then insert the guide tube into the balancer outer tube; b. Then put the balancer inner tube into the guide tube, put the inner tube on Balance spring and balance spring, put the inner tube sleeve on the upper end of the balancer inner tube, adjust the direction of the roller shaft, press down the pressure rod connected with the inner tube sleeve; c, continue to press down the inner tube sleeve, when the balancer inner tube and the balancer After the outer tube is 90 degrees relative to each other, stop pressing down and rotating; d. Finally, lift the pressing rod up, take out the balancer assembly, and complete the assembly action. In the actual assembly process, the present invention is quite simple to operate, saves time and effort, is safe and reliable, can effectively improve assembly efficiency and assembly quality, and reduce tooling manufacturing costs.

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...
