发动机齿轮组件压装专机电气控制与气动系统设计

摘要

根据发动机装配线专用机床和压模的运动要求,分析了齿轮组件压装工艺流程,设计了压装专机电气控制与气动系统.基于S7-200型PLC,采用光电传感器实时检测专机和压模运动位置,用顺序功能图设计了齿轮组件的压装过程,用梯形图语言设计专用机床运动控制程序.实践证明,该电气控制和气动系统完全满足齿轮组件压装专机的技术要求.%According to the engine assembly line for special machine tools and mould movement requirements, it analyzes the gear assembly crimping process, designs the electrical control and pneumatic system of special machine.Base on the S7-200 PLC, it applies the photoelectric sensor to detect real-time plane mould movement position, designs a sequential function chart and determines the press-fit process state diagram, develops the stepped ladder diagram and special machine motion control program.The application proves that the electric and pneumatic control system can meet the plane gear assembly press fit the technical requirements.
