4040A型喷油器垫片分选控制系统的设计

喷油器垫片分选关系到喷油器产品的品质，传统垫片分选需大量工人进行人工分选，属于劳动密集型工作，为降低工人的劳动强度，设计了4040A型喷油器垫片分选控制系统。分选机采用PLC作为主控系统，通过伺服电机控制模拟压力，在运动过程中测量喷油体组件和后顶针组件的长度，再经计算选出合适的垫片；同时介绍了垫片分选机的工作过程、实现方法等。运行结果表明，该控制系统能实现自动测量、自动选取垫片的功能，达到预期效果。

Design of 4040A Injector Gasket Sorting Control System

Injector gasket sorting is related to the quality of the injector. Traditional gasket sorting is labor- intensive work. To reduce work intensity, we designed 4040A injector gasket sorting control system. In this paper, we use PLC as control system. The simulation of the opening pressure is controlled through the servo motor; and during exercise we measured injector assembly and the rear thimble assembly length, and then chose proper gaskets. The paper introduces the working process of the gasket sorting machine and the implementation method. Practice shows that this system has achieved the expected goal in that it can measure and sort gasket automatically.
