薄壁零件如衬套等,在其圆周方向和轴向钻许多孔,我们采用了附图所示的钻模,效果很好。使用前将六角扁螺母2调整好,使衬套定位座4、分度盘3相对于夹具体7能自由地转动,但不能过松。使用时将压板6拉到与拉杆5同一轴线位置,把工件套入定位座4中,后将压板6置于图示的垂直位置,拧紧翼形螺母1使工件夹紧,即可钻孔。要分度时,只要转动翼形螺母1和压板6,则夹 Thin-walled parts, such as bushings, etc., drilled many holes in the circumferential direction and in the axial direction. We used the model shown in the figure to work well. Before use, adjust the hexagonal flat nut 2 so that the bushing positioning seat 4 and the index plate 3 can freely rotate relative to the clamp body 7, but can not be loosened. When used, the pressure plate 6 is pulled to the same axial position as the pull rod 5, the workpiece is set into the positioning seat 4, the pressure plate 6 is placed in the vertical position as shown in the figure, and the wing nut 1 is tightened to clamp the work piece for drilling. To indexing, just turn the wing nut 1 and the platen 6, the clip
