一、简介我厂设计制造的万能极座标钻模,系通用可调夹具,调整和使用均较简便。利用插销以工件内孔、外圆或非圆表面等部位定位,易于较准确地钻、铰孔径在14毫米以下,按极座标标注孔位的孔系。如图1(a)、(b)、(c)所示为被加工零件。用以加工大件轴孔端面各螺孔也很方便。

I. Introduction I design and manufacture of universal polar coordinates drilling, Department of general adjustable fixtures, adjustment and use are more simple. The use of the pin to the workpiece hole, cylindrical or non-circular surface and other parts of the location, easy to more accurately drill, reaming 14 mm diameter below, according to the polar coordinates of the hole marked hole system. As shown in Figure 1 (a), (b), (c) shows the workpiece to be machined. It is also very convenient to process the screw holes on the end face of large-size shaft hole.
