一、概述一般的机械定位,结构简单,但是精度不易做得很高,分辨率也较低。例如刻度盘定位,是靠丝杠自锁与人工对准刻线来定位的,误差因人而异。若利用滚珠丝杠,则不能有效定位。如选用机电结合的形式,利用圆形编码盘(光栅、旋转变压器等)进行细分,分辨率做得很高也有一定困难,而且这种定位机构在用滚珠丝杠时,要有其他的锁紧元件。所以这 First, an overview of the general mechanical positioning, the structure is simple, but the accuracy is not easy to do very high resolution is also low. For example, dial positioning, screw self-locking and manual alignment marks to locate, the error varies. If you use the ball screw, you can not effectively locate. Such as the use of mechanical and electrical integration of the form, the use of circular encoder (grating, resolver, etc.) for subdivision, the resolution is very high and there are some difficulties, and this positioning mechanism with the ball screw, there must be other locks Tight components. So this
