摘要
为提高产品加工精度及生产效率,将现有FANUC-0id数控铣床升级为具有自动换刀系统(ATC)的加工中心。通过对比选择斗笠型无机械手换刀方式以减少复杂的机械结构所带来的不稳定性,进而提高加工中心安全系数。为克服直流电机换向问题及自身结构复杂等缺点,采用交流伺服电机作为刀盘驱动装置。在ATC工作过程分析基础上,对其控制系统硬件电路及软件进行设计,提出一种双向分级换刀方式并设计ATC换刀过程。通过实验对比传统单向旋转换刀方式和双向分级换刀方式的换刀时长,得出双向分级换刀方式在同一扇区内可以快速进行换刀的结论。研究结果为数控机床升级加工中心优化设计和控制策略提供依据。
In order to improve preciseness and efficiency of manufacture process, FANUC-0id CNC milling machine is upgraded to machine center with automatic tools changer （ATC）. Non-manipulator tool changer is selected for reducing the instability of complicated mechanical structure, thus enhance the safety factor of machine center. For eliminating the commutation problems and complicated structure of DC motor in ATC, AC servo motor is selected as the driver of ATC tools storage. Base on analysis of ATC working process, the control system hardware electronic circuit and software are designed, and the bidirectional classified tool changing mode （BCTCM） /s proposed and designed. Traditional unidirectional rotating tool changing mode and bidirectional classified tool changing mode are compared by experiments, and the results provide foundation for the optimization design and control strategy of numerical control machine.
