本钻模(附图)是钻削放大器支架上光孔和螺纹底孔用,放大器支架的六个面上均有孔加工。钻模采用翻转式和铰链回转式钻模板结构,可使工件在一次装夹中加工完全部孔。这样,既保证了定位准确、可靠,又使钻模结构紧凑、夹紧方式新颖,同时还节省了装卸时间。工件在钻模中的定位及夹紧: 被加工工件是压铸件,底平面及左侧面已经加工,现以两个互相垂直的平面和中心线为定位基准,将工件底面放在三个支承钉11上定位,侧面用两个活动定位销
The drilling die (with photos) is used for drilling amplifier bracket hole and the bottom hole for the screw, the amplifier bracket has six holes on the surface processing. Drill with flip and hinge rotary drilling template structure, the workpiece can be processed in a complete installation of the hole. In this way, not only ensures the accurate and reliable positioning, but also makes the drilling die structure is compact, the clamping method is novel, and meanwhile saves the loading and unloading time. Workpiece positioning and clamping in the die: the workpiece is machined die casting, the bottom plane and the left side has been processed, are two perpendicular to each other the plane and the centerline for the positioning of the base, the workpiece on the bottom of the three support Pin 11 on the positioning, the side with two activities positioning pin
