Control System of Lifting and Lowering Ruling Diamond Mechanism of Grating Ruling Engine

In order to improve the ruling performance of the traditional grating ruling engine, a novel lifting and lowering ruling diamond mechanism is presented. The grating ruling engine and the mechanical structure of the lifting and lowering ruling diamond mechanism are introduced. The piezoelectric-driven stage is chosen as the actuator. A control system of the mechanism is established, and the hardware design is accomplished. Based on the demands of the grating ruling process, the software of the control system is designed. The system carries out communication through serial bus, and the serial communication protocol is devised. The practical results indicate that the mechanism is of simple structure, real time control, high precision, and doesn’t bring in any vibration and heat. The quality of the ruling grating and efficiency of the ruling process are improved.
