通盖是我厂产品中的零件,其端面上钻削四个螺孔,过去加工时,以中心孔定位,将钻模板套在工件上,用压板、螺栓、垫圈、螺母紧固后钻孔。加工完毕,须一一拆卸,这样,辅助时间长,生产效率低。为节省辅助时间,提高生产率和保证在零件径向增加一油孔(要求与端面孔一次装夹加工完),特设计制造了一套快速装卸通盖钻模(附图),在一套钻模上同时钻削端面上孔及径向孔,且钻径向孔的钻模位置,可随通盖三种不同直径而变
The cover is a part of our factory products, drilling four screw holes on the end face, the past processing, the center hole positioning, the drilling template set on the workpiece, with the pressure plate, bolts, washers, nuts, after drilling . Processing is completed, must be one by one disassembly, so that auxiliary time, low productivity. In order to save the auxiliary time, increase the productivity and ensure that an oil hole is added in the radial direction of the part (requiring a clamping process with the end face hole), a set of quick loading and unloading pass-through drilling dies (with photos) Simultaneous drilling on the hole on the end face and the radial hole, and drilling radial hole drilling position, with the lid can be changed with three different diameters
