摘要
为了提高齿条磨齿机加工精度和效率,提出了齿条磨齿机数控化方法。数控齿条磨齿机控制系统以可编程控制器为基础,完成砂轮的旋转运动、工作台的直线运动和液压缸的纵向进给运动;应用光栅尺显示砂轮的垂直进给量和反馈机床分齿运动,采用人机互动界面输入控制命令和加工数据,并实时反映机床运动情况。给出了控制系统结构框图,详细介绍了系统的硬件设计和软件设计。数控齿条磨齿机试用结果表明该控制系统运行平稳,加工精度符合要求。
In order to improve the processing precision and efficiency of rack-ground machine,a numerical control method was proposed.The rack-ground machine's control system was based on programmable logic controller(PLC)to finish the rotation of grinding wheel,the straight-line motion of grinder worktable and the long feed motion of oil cylinder.The grating scale was used to show the vertical feed amount of the grinding wheel and gain the teeth-separated feedback.The touch screen was applied to input control commands and work data and real-time output the machine state.The control system structure diagram was presented,the hardware and software design was further reported.The test results indicate that the control system is stable and the machining accuracy meets the requirements.
