基于S7-200系列PLC系统的滑动轴承对接平面拉床技改设计

Reformed Design of Broaching Machine for Bisect Plane Machining of Sliding Bearing Based on PLC S7-200

内燃机等设备中的对开滑动轴承加工工艺关键工序之一是对接平面拉削加工,提高该专用拉床加工质量和效率的技术要点是使启动上料、工件定位、清扫拉屑、执行夹紧、定位复位、拉削、夹具松开及退料等拉削过程中所有动作正确无误。本文在简述对接平面拉削工艺流程的基础上对采用S7-200系列PLC进行全自动对接平面拉床控制系统技术改造设计的过程予以分析阐述,并对相关技术问题给出说明。

The finish machining of the bisect plane of bisect sliding bearing is the key working procedure of the machining of such products.The automatic orientation, clamping, directional return,broaching, clampin/loosing, automatic feeding and withdrawal of this special broaching machine in the broaching process are the key technical points for improving the machining quality and work eitlciency in the procedure. This paper analyzed the machining process of this working procedure, discussed the reform process of applying PLC $7-200 on the machine tool control system of automatic hydraulic broaching machine for Bisect Plane Machining, and explained the relative technical problems.
