我们利用“三点成一平面”的原理,设计制成了一个通用性强的能加工任意方向斜面的夹具。该夹具结构简单、使用方便、精度较高,适用于单件小批量的小件加工。该夹具可制成大小数种规格。如图所示,夹具由面板,持球圈,定位柱,垫片,万向螺栓及底板等主要零件组成。面板可安装工件或机床附件(分度回转工作台及三爪,四爪卡盘)。面板上铣有二条定位槽并钻有几个螺孔。根据工件倾斜轴线的方向,决定底座上分布的三只定位柱的
We use the “three into a plane” principle, designed and manufactured a versatile can handle any direction of the inclined plane fixture. The fixture structure is simple, easy to use, high precision, suitable for small pieces of small pieces of single-piece processing. The fixture can be made in several sizes. As shown in the figure, the fixture consists of the main parts such as the panel, ball cage, positioning column, gasket, universal bolt and base plate. Panel can be installed on the workpiece or machine annex (indexing rotary table and three claws, four-jaw chuck). Panel milling two positioning slots and drill a few screw holes. According to the direction of the tilt axis of the workpiece, the three positioning posts distributed on the base are determined
