摘 要
数控加工的加工精度高，生产率高，能减轻操作者劳动强度、改善劳动条件，有利于生产管理的现代化以及经济效益的提高，它的发展和运用，影响着制造业水平高低，实现生产过程的数控化，已经成为当今制造业的发展方向，所以非常值得我们去研究。
本设计通过对八工位卧式电动控制刀架的工作原理的分析，确定了多种方案，综合考虑各种方案的优缺点、性价比后，采用电动回转刀架。其刀架机构的主要部件包括减速传动机构、刀架的抬起机构、锁紧与转位精定位机构等，控制系统软件包括控制系统的选择，控制系统软硬件的设计，收发信电路的设计等，设计中所采用螺杆抬起机构、端齿盘定位机构和单片机控制系统都计较经济实用，适合我们我国现阶段数控机床的发展需要。

ABSTRACT
The numerical control processing's working accuracy is high, the productivity is high, can reduce the operator labor intensity, the improvement work condition, is advantageous in production management modernization as well as the economic efficiency enhancement, its development and the utilization, are affecting the manufacturing industry horizontal height, realizes the production process numerical control, already became now the manufacturing industry development direction, therefore is worth us studying. this design through to eight location horizontal type electric control tool rest's principle of work's analysis, had determined many kinds of plans, after overall evaluation each kind of plan good and bad points, performance-to-price ratio, uses the electrically operated turret saddle. Its tool rest organization's major component including the reduction gear organization, the tool rest lifts the organization, to lock and to index the fine detent mechanism and so on, the control system software including control system's choice, the control system software and hardware's design, receives transmitting circuit's design and so on, in the design uses the screw rod to lift the organization, the end tooth plate detent mechanism and the monolithic integrated circuit control system haggles over the economy to be practical, suits our our country present stage numerically-controlled machine tool's development need. key word eight locations, electrically operated tool rest, automation, 89C51 monolithic integrated circuit.
Keywords eight locations, electrically operated tool rest, automation, 8051 monolithic integrated circuit.
