基于磨削防碰撞系统的研究

Research of the Anticollision System Based on Grinding

在轴承套圈磨削加工过程中,防碰撞是磨削加工过程中一大监测难点。磨削砂轮在轴承套圈磨削过程容易与零件或机床部件发生碰撞,提出基于对磨床主轴功率变化的采集和相应的信号提取,通过智能中央控制器对采集的信号进行处理分析,并与数控系统或PLC通讯控制磨床上下料机构的运动。结果表明:控制系统根据不同的磨削状态,发出不同的控制信号,机床执行不同的加工程序,有效地防止碰撞的发生。

In the process of bearing ring cutting,anti-collision is a major monitoring difficulty in grinding process.Grinding wheel is easy to collide with parts or machine tool parts during the grinding process of bearing ring,Based on the acquisition of power variation of grinding machine spindle and corresponding signal extraction,the collected signals are processed and analyzed by an intelligent central controller,And communicates with the numerical control system or PLC to control the movement of the feeding and discharging mechanism of the grinding machine.The results show that the control system,according to different grinding conditions,send out different control signals.The machine tool executes different processing procedures which effectively prevent collision among them.
