- 自动换刀系统设计论文数控车床将向中高档发展，对数控刀架需求量将大大增加。随着数控车床的发展，数控刀架也向快速换刀、电液组合驱动和伺服驱动方向发展。
本设计采用电液组合驱动，主要完成了八工位卧式刀架的机械结构设计和利用三菱FX2N可编程控制器（PLC）对自动换刀系统的控制系统进行设计。机械设计主要包括分度机构及定位机构的选择和刀架主轴的设计等。控制部分为自动和手动换刀两种工作方式。
关键词 数控刀架，PLC控制，液压控制

ABSTRACT
Numerical Control lathe will be developed to middle and senior grade in the future. It is estimated that the demand for NC tool carrier will be much greater. NC tool start to the rapid tool change, electrohydraulic servo driving and portfolio-driven direction with the development of NC lathes.
The paper takes electrohydraulic driving. It was discussed that mechanical design and control system design by Mitsubishi FX2N programmable logic controller (PLC) of the eight engineering automatic tool change. Machinery part includes the positioning tools and the degree of positioning choices and tool spindle design. Control part is divided into auto control and manual control.
Key words ATC，PLC control，Hydraulic control
