圆柱形的工件在磨削时,常常要把工件长度加长约15公厘,作为加工中装卡工件之用,加工完以后,这段加长部份,往往就浪费掉了。如果采用下面介绍的方法夹持工件、这种浪费就可以避免。在外圆磨床的主轴孔内,安装一个削边的顶针1如图1所示,在顶针1的削边部份上固定-带动销2,带动销2插在工件顶针孔旁边的小孔内,借以带动工件。当磨床主轴旋转时,带动销2便能带动工件进行磨削。由于带动销2的位置是固定的,因此工件
Cylindrical workpieces grinding, often to extend the length of the workpiece about 15 mm, as the processing of cards installed in the workpiece, after processing, this extension of the part, often wasted. This waste can be avoided if the workpiece is clamped as described below. In a cylindrical grinding machine spindle hole, the installation of a beveled thimble 1 shown in Figure 1, the thimble 1 in the cutting edge portion of the fixed - driven pin 2, led pin 2 inserted in the hole near the workpiece thimble hole , To bring the workpiece. When the grinding machine spindle rotation, driven pin 2 can bring the workpiece to be ground. Since the position of the pin 2 is fixed, the workpiece
