产品零件中,有许多端面上带有等分孔的轮盘类或箱体类零件。这些零件,在产品试制或单件小批生产过程中,同一个圆周上的各等分孔加工,一般使用划线后钻孔的方法。生产效率很低,孔距尺寸及等分角度精度要求稍严格时,就达不到产品图纸的要求,如果制造专用钻具又很不经济。可调式钻模板,可以对孔距尺寸,等分角度,根据产品图纸尺寸要求进行任意调整。一个模具可适用于多种零件。其结
Among the product parts, there are many roulette or box-type parts with equally spaced holes on the end face. These parts, in the product trial or a single small batch production process, the same circle on each hole processing, the general use of the method of drilling after scribing. Production efficiency is very low, the pitch of the hole size and the accuracy of bisect angle is slightly more stringent, the product drawings can not meet the requirements, if the manufacture of special tools and very uneconomical. Adjustable drilling template, can pitch size, equally divided angle, according to the size of the product drawings to be adjusted. A mold can be applied to a variety of parts. The knot
