在夹具的定位中经常采用菱形定位销。菱形定位销结构虽简单,但其加工的几何形状及尺寸精度常达不到要求,以致造成废、次品,影响工件定位精度。在分度盘上铣削菱形定位销,按计算出的旋转角α、β及切削深度T来加工,即可加工出几何形状及尺寸精度较好的菱 Diamond positioning pins are often used in fixture positioning. Although the structure of the diamond positioning pin is simple, its machining geometry and dimensional accuracy often fail to meet the requirements, resulting in waste, defective, affecting the workpiece positioning accuracy. In the index plate milling diamond positioning pin, according to the calculated rotation angle α, β and cutting depth T to processing, you can work out the geometric shape and size of the better precision Ling
