阐述了非成型刀轴承轴圈自动车床液压系统的设计。研制了以可编程控制器(PLC)为核心的非成型刀轴承轴圈自动车床液压控制系统。对控制系统的硬件结构、软件组成等作了详细介绍,实现了对非成型刀轴承轴圈自动车床液压系统的控制,达到了预定的控制要求。 The design of the hydraulic system of automatic lathe with non-forming knife shaft bearing was expounded. A hydraulic control system of automatic lathe with non-forming knife shaft bearing was developed with PLC (programmable logic controller) as the core. The hardware structure and software composition of the control system are introduced in detail. The control of the automatic lathe hydraulic system of the non-forming knife shaft bearing ring is achieved and the predetermined control requirements are met.
