Z3080摇臂钻床加工的零件大多数是外形尺寸较大,重量较重的零件(重达数吨),当钻削导向套螺孔需等分等距时,必须实现准确定对中心,才能使零件装配时互换通用。 附图是我厂使用的操作简便的定心胀紧钻模。使用时操作偏心夹紧手柄1,带动锥盘7移动压缩弹性钻模体5,使其变形部均匀弹 Z3080 most parts of the radial drilling machine parts are larger size, heavier parts (weighing tons), when the drilling guide screw holes need to be equally divided, you must achieve accurate centering in order to enable Parts interchangeable when assembled. The drawing is a simple and easy centering and expanding drilling tool used by our factory. When operating the eccentric clamping handle 1, drive the cone 7 to move the compressed elastic drill body 5 to make the deformed part evenly
