饲料环模机械加工钻床的自控系统设计

Design of automatic control system for feed ring die of mechanical processing driller

为了提高饲料环模的机械加工效率,降低生产成本,设计了一种基于AVR单片机的饲料环模机械加工钻床的自动控制系统。实验结果表明,该系统能够自动进刀,自动排屑,自动分度;进刀时以设定进刀速度恒速进刀;分度控制全部由程序完成,故障率低、分度重复精度高;具有自动修正功能,可对任意孔数的饲料环模进行精确分度钻孔加工;可重复进行定位、阶梯孔、通孔、扩孔、铰孔等加工工序,使用极为方便。

In order to improve the processing efficiency of feed of ring die and reduce production costs, this paper designs an automatic control system for feed ring die based on AVR MCU. The results show that this system could automatic feed, automatic chip-dumping, automatic indexing. The speed of feed can be set to constant, and the indexing is controlled by program, which has low fault rate and high precision repeated indexing. The system could process ring die for any number of drill by precision index- ing, in addition, which could repeated machining operation for the location, step hole, via, reaming, etc.
