我所分厂是专门生产滚珠副的厂家,在生产中,经常遇到螺母上孔的加工问题,以往我们设计了以防尘圈孔定位的专用钻模来加工,因螺母的尺寸及孔的分布千变万化,精度要求各异,故钻模的种类繁多,给生产管理带来诸多的不便。为此,设计了一种可调式通用钻模,很好地解决了问题,介绍如下(见附图): 使用时,工件以圆柱面定位,并通过Φ250的三爪卡盘夹紧,刻度盘3每格0.02mm,摇动螺杆2上的方头来调整孔距尺寸,调整好后予以锁紧。分度盘12上
Our factory is specializing in the production of ball vice manufacturers, in the production, often encountered nuts on the hole processing problems, in the past we designed to dust ring hole positioning dedicated drilling to processing, because the nut size and hole The distribution of ever-changing, precision requirements vary, so a wide range of drilling die, to the production management to bring a lot of inconvenience. To this end, designed an adjustable universal drill, a good solution to the problem, introduced as follows (see attached): When used, the workpiece cylindrical positioning, and through the Φ250 three-jaw chuck clamping, dial 3 each 0.02mm, shake the square on the screw 2 to adjust the hole size, adjusted to be locked. The dial 12 is on
