数控滚齿机的三轴联动 PLC 控制研究
中文摘要
数控系统控制滚齿机,从二轴升级到多轴联动,较之传统铣床加工工艺具有明显
优势,提高效率十倍以上。可编程序控制器PLC(Programmable Logic Controller)控制
的数控滚齿机是其中一种有效手段,由PLC的高速脉冲输出模块来控制伺服电机、驱
动伺服马达,实现加工过程。用人机界面HMI(Human Machine Interface)来作为用户
的操控对象。
本文以台达PLC控制的滚齿机为例,通过对齿轮的加工工艺方法的研究,解决了
系统的三轴联动设计,进行了驱动电路、保护电路的设计,编写了整个系统的控制程
序,采用台达dop-B系列触摸屏作为用户对话的窗口,可进行人工、自动操作和参数
调整。
利用三个伺服电机单独控制滚刀轴、工件轴、进给轴,代替了电子齿轮箱的传动;
提出了三轴联动的思路,实现了回原点功能,利用展成法进行小模数齿轮的加工;采
用电机、联轴器、滚珠丝杠等硬件来减少机床误差;加工过程中,AA级滚刀减少加工
中的过程误差;引入了误差补偿控制系统,降低了电机和各个轴之间的传动误差,加
工精度得到了保证,简化了设备机械机构。经过测试,加工小模数齿轮精度可达到6-7
级,达到了初期设定要求。

Study on three-axis gear hobbing machine PLC control
Abstract
Compared with the previous traditional process, the gear hobbing machine which is
controlled by Numerical Control (NC) system has obvious advantages. The improve
efficiency is more than ten times. The NC gear hobbing machine controlled by PLC is one
of the effective means. By using the PLC high speed pulse output module to control the
servo motor,drive the servo motor and at last to achieve the machining process. It is also
using HMI as a user manipulation of the object.
Taking the gear hobbing controlled by Delta PLC as an example, this article deals
with the solving system of triaxial linkage design. The design of the driver circuit , the
protect circuit and the writing of the system control procedures pleted by the gear
processing technology method research. The NC gear hobbing machine can have a manual
or automatic operation and parameter adjustment under the user interface of the Delta
dop-B series touch screen.
The NC gear hobbing machine use the three servo motor control alone hob shaft,
workpiece axis, feeding shaft instead of the electronic gearbox tra
