Description

Technical Field

[0002] Pneumatic nail guns are also called pneumatic nailing machines. Pneumatic nail guns use the air pressure generated by the air pump (air compressor). The high-pressure gas drives the firing pin in the nail gun cylinder to do hammering motion, nailing the nails in the nail clip into the object or shooting out the nails. The pneumatic nail gun includes a gun body assembly and a magazine assembly. The gun body assembly is composed of a gun body, a cylinder, a firing control mechanism, a firing pin assembly (gun tongue), a buffer pad, a gun mouth, a gun groove, etc. The firing pin (piston) reciprocates in the cylinder through the firing control mechanism by using the pressure difference between compressed air and atmospheric pressure. The magazine assembly is composed of accessories such as a gun head, a gun cover, a fixed magazine, and a movable magazine. The nail is sent to the gun cover groove through a compression spring or a tension spring. When the firing pin comes out of the gun mouth, the nail is driven out. When assembling the piston and the sealing ring of the existing pneumatic nail gun, the assembler needs to manually open the sealing ring and put it on the piston, which has low assembly efficiency and high labor intensity for the assembler. Therefore, it is very necessary to design an automatic assembly device for the sealing ring. Summary of the invention
