在车削工件时,要求操作者装夹工件迅速,这是提高工作效率的重要途径。我们购买的轴承座为一不规则零件,使用于盐田塑(?)机这一非标准机械,该半成品轴承座内径大小不一,外形大小各异,外部定位基准面很难确定,在车床上装夹时非常麻烦,工件效率很低。为此,我们自制了如图所示的车床定位找正用顶尖。 When turning the workpiece, the operator is required to fasten the workpiece quickly, which is an important way to improve work efficiency. The bearing housing we purchased is an irregular part, which is used in Yantian Plastic (?) Machine, a non-standard machine. The semi-finished product bearing housing has different inner diameters, different sizes and different external positioning datums. Clamping very troublesome, the workpiece is very inefficient. To this end, we made a self-made lathe positioning as shown to find the top.
