摘要
介绍了提高超长进给机构精度的几种方法,提出了一种新的方案,即将齿轮齿条传动结构应用于数控机床超长进给机构,采用电气消隙形式,解决了齿轮与齿条间的反向间隙;机械的闭环形式,消除了电机到齿轮之间的所有背隙,从而保证进给运动的高精度,并应用于实际机床生产中。
Some techniques of enhancing the super long feeding mechanism accuracy are introduced in this paper,then a new method is given,that is,rack-and-pinion structure is used in the CNC machine tool with super long feeding mechanism.The problem of rack-and-pinion backlash compensation is solved by using electromotor driving system,and the rest backlash is eliminated by mechanical close-roop.So the feeding precision is higher,and the system is applied to practice.
