摘　　要：介绍了表面微坑超声加工的基本原理 ,分析了相位控制频率跟踪的原理及实现方法 ,给出了表面微坑超声加工装置超声电源的总体结构。并采用PIC单片机、74HC4 0 4 6锁相环、UC3875移相控制器等器件设计并实现了具有频率自动跟踪、输出功率可调节的超声电源。表面微坑超声加工试验表明 ,该超声电源可实现频率自动跟踪 ,且工作稳定 。The fundamental of ultrasonic machining method of micro-pits of working surface is introduced in this paper, and the principle and method of phase controlling frequency tracking are analyzed, and the whole structure of ultrasonic power for ultrasonic machine of micro-pits of working surface is presented. Based on PIC single chip?74HC4046 PLL? UC3875 Phase shift resonant controller, the ultrasonic power which has the characteristic of frequency auto-tracking?adjustable output power is designed and realized. The experiment of ultrasonic machining of micro-pits of working surface indicates that the ultrasonic power working stably can meet the need of machining of micro-pits of working surface.
