Abstract

The assembly technology is the critical step in manufacturing that determine the production cycle and the production quality,especially in the complex product and high technical requirements situations.Process equipment is integrant to ensure assembly quality and increase assembly efficiency in assembly process.The CQ7.62mm general-purpose machine gun is a good gun,the receiver is a square stamping production have good strength and reliability.It is a complex shape andhigh technical representative part.The step of the receiver assembly technology and the tooling design is the basis to improve the   quality and the assembly efficiency.This article studies the CQ7.62mm general-purpose machine gun structure drawing,the assembly and the drawing of the receiver,got to know the gun receiver assembly tech-nical requirements.And refer to existing assembly technology and equipment and analyze the structural features and the assembly technical requirements to rework the assembly technology and use UG to reb-uild the assemble equipment.
