轴向孔加工,通常是把刀具直接装在尾座套筒中,当对工件的轴向面进行多工位加工时,必须更换刀具。为了缩短辅助时间,提高生产效率,采用多位刀座是有效方法之一。这里推荐几种多位刀座。三位刀座:结构如图1所示。该刀座以锥柄6安装在钻床或车床尾座上。扇形板4沿轴3转位,借助弹性定位器5使之固定。在扇形板的三个方向上装有锥度套2和钻头1,同时可装三把轴向刀具,以进行打中心孔、钻孔、
Axial hole machining, usually the tool is mounted directly on the tailstock sleeve, when the workpiece axial surface multi-station processing, you must replace the tool. In order to shorten the auxiliary time, improve production efficiency, the use of a number of knife seat is one of the effective methods. Here are several recommended seat. Three knives seat: the structure shown in Figure 1. The knife seat taper shank 6 mounted on the drilling machine or lathe tailstock. The sector 4 is indexed along the axis 3 and fixed by means of a spring retainer 5. In the three directions of the fan plate is equipped with a taper sleeve 2 and a drill bit 1, and at the same time, three axial tools can be installed for centering, drilling,
