当螺帽(图1)需要钻削距端面5±0.2毫来的ф4孔时,使用该钻模定位可靠。将工件装在“V”型块6上(图2),卡上转动垫圈1,然后扳动手柄2,通过偏心凸轮3的作用,使轴7移动,带动转动垫圈1压紧工件。通过定位套8使工件可靠定位。轴7上装有ф2.5的销4,可在定位套8的键槽内滑动,以防止轴7转动。钻孔后扳动手柄2松开偏心凸轮,拨开转动垫圈即可取出工件。
When the nut (Figure 1) needs to drill ф4 holes 5 ± 0.2 millimeters from the end face, it is reliable to use this drilling die. The workpiece is mounted on the “V” block 6 (Figure 2), the washer 1 is rotated on the card, and then the handle 2 is pulled. Through the action of the eccentric cam 3, the shaft 7 is moved and the rotating washer 1 is pressed against the workpiece. The positioning sleeve 8 enables the workpiece to be positioned reliably. The shaft 7 is equipped with ф2.5 pin 4, can slide in the keyway of the positioning sleeve 8 to prevent the shaft 7 from rotating. After drilling, pull the handle 2 to release the eccentric cam and remove the workpiece by turning the washer.
