The paper employs the theory of the layout, design and function of the automatization manufacturing system and studies on the practice and process of cylinder of automobile in the Chang An Corp. author improve on the process the JL472Q, JL 474Q and 1L475Q cylinder to make a flexible manufacture line for the three kinds cylinder. The line composes nine facility (five horizontal machine center, two specific machine), two automatic lines. The FMIL have high utilizable ratio, stable throughput, and good reliability and solve the bottleneck in the process the cylinder of automobile. It contends Chang An corporation for enlarging production and entering into the WTO with quickstep.

本文针对长安汽车集团公司JL72Q、JL474Q、JL475Q三种汽车气缸体的加工工艺特点并结合工厂生产实际，对缸体的加工工艺进行了系统的研究改进，依据现代自动化制造系统的规划、设计和运行原理对三种气缸缸体的机械加工柔性自动线进行了总体设计，规划出了一条缸体机械加工柔性自动线，该自动线采用了9台加工设备(其中5台卧式加工中心，2台专用机床)，2条自动线的设计方案，整个柔性加工线设备利用率高、生产能力稳定、可靠性好，解决了企业生产中的发动机气缸体加工的瓶颈问题，适合长安汽车集团企业扩大生产与率先进入WTO战略的需要。

This equipment uses the mesa structure, has the controller, the sensor (electro-optical type, inductance type, color, magnetic induction type), the revolving encoder, the electric motor, the conveyor belt, the air cylinder, the solenoid valve, the direct-current power supply, the air filtration reductor, the programming practice kneading board and so on, the constitution model integration of machinery teaching training installment.

该装置采用台式结构，配有控制器、传感器（光电式、电感式、颜色、磁感应式）、旋转编码器、电动机、输送带、气缸、电磁阀、直流电源、空气过滤减压器、编程练习面板等，构成典型的机电一体化教学训练装置。

With the special kinematics and kinetics law of major-minor connecting rod mechanism in gas engine,based on expression function integrated into regular curve and optimizing module provided by UG software,the optimized structural parameters of major-minor connecting rod mechanism were educed through minimizing the differences tribology characteristic between in piston of major cylinder and piston of minor cylinder,and kinematics and kinetics characteristics were reappeared with emulational curve mode.

根据关节式曲柄连杆机构独特的运动学、动力学规律，利用UG软件所提供的表达式、规律曲线和优化等模块，给出使主、副气缸的摩擦学特性尽量保持一致的最佳结构参数，并以仿真曲线的方式再现了运动学和动力学特性的变化规律。

JG-19 adopt exact numeric control, it can keep ten programme and you can rejigger it freely. Use double impulses can make sure the jointing fastness and good surface. Seven segment LED display all seal data. JG-19 uses double gas jar power, desk can litre and lower by stepless and use hand lock. The electrode can adjust in all the position, so worker can seal all kinds figure and measurement easily.

JG-19采用精确的数字控制，能预存10个程序，并可随意更改、调用；运用双脉冲可确保焊接牢固、焊点美观；7段LED显示各焊接参数，JG-19更采用双气缸动作，工作台无级升降手拧式锁紧，电极立体式调节，使操作者可以轻易地焊接各种形状、尺寸的材质。
