在我厂生产的台钻产品中,有几种形状基本相似的套筒零件(如图1所示),采用钻模钻削不同孔距的φ6孔。为了适应零件 L_1和φD 尺寸的变化,设计成如图2所示的游标式可调钻模,提高了钻模的通用性。一、游标式可调钻模的使用1 根据工件外径尺寸φD,松开夹紧螺钉1和紧定螺钉7,使钻模板4沿导柱3上下移动来确定钻模板与工件的距离,并拧紧紧定螺钉和夹紧螺钉。2.根据工件孔φ6对工件端面 A 的距离尺寸 L_1,松开锁紧螺钉17使滑块9沿 V 型块12表面前后移动,
In our bench drill products, there are several kinds of sleeve parts with similar shapes (as shown in Fig. 1). Drill holes with different hole pitches are drilled. In order to adapt to the changes of parts L_1 and φD, a cursor-type adjustable drill as shown in Fig.2 is designed to improve the universality of drilling. First, the use of cursor adjustable drill 1 according to the workpiece diameter φD, release the clamping screw 1 and set screws 7, so that the template 4 along the guide column 3 up and down to determine the drilling template and the workpiece distance, and Tighten the set screw and clamping screw. 2. According to the workpiece hole φ6 on the workpiece end face A distance dimension L_1, loosen the locking screw 17 so that the slider 9 moves back and forth along the surface of the V-shaped block 12,
