Description
Technical Field
The invention relates to the technical field of firearm assembly, in particular to a method for press mounting of a gun rack balancer.
Background
With the increasing variety of large-caliber machine guns, the gun frames and the balancers thereof are applied more and more widely. The method is widely applied to the battle platforms such as battle vehicles, battle ships and fighters. The gun rack balancer consists of inner pipe, balancing spring, inner balancing spring and outer pipe parts. The balance spring and the inner balance spring are assembled in the inner pipe and the outer pipe, and the tenon on the excircle of the inner pipe is buckled with the tenon on the inner hole of the outer pipe.
When assembling the balancer parts, a worker first clamps the outer pipe part of the balancer to flat tongs. The clamping requirement is very reliable, and the clamping is slightly loosened, so that safety accidents are easily caused. Then the inner balance spring and the balance spring are put into the inner hole of the outer pipe part in sequence, and then the inner pipe is put at the other end of the balance spring. The tenon direction on the excircle of the inner tube and the tenon direction of the inner hole of the outer tube are staggered. Two workers insert an iron rod into the connecting hole at the upper end of the inner pipe. Downward force is simultaneously applied to both ends of the iron rod to overcome the two spring forces. Meanwhile, workers are required to adjust the assembly posture at any time, the interference of tenons of the inner pipe and the outer pipe is avoided, and the inner pipe is sleeved into the outer pipe. After the pipe is sleeved, the pipe is continuously pressed to the position where the tenons of the inner pipe and the outer pipe do not interfere with each other, the inner pipe and the outer pipe rotate by 90 degrees relatively, and the tenons of the two pipes are firmly buckled with each other. Finally, the iron rod is taken down, the flat tongs are loosened, and the assembled balancer is taken down from the flat tongs.
The spring force of two springs reaches hundreds of newtons at the buckling position of the inner and outer tubes, and the central lines of the inner and outer tubes cannot coincide with each other when the inner and outer tubes move axially relative to each other. In actual operation, the operation position and the posture of the body of a worker are often improperly adjusted, the spring force ejects the inner pipe and the outer pipe, the safety accident of object striking is easy to occur, and great potential safety hazards exist. Potential safety hazards also exist when the balancer is disassembled.
