我厂在镗削如图1所示的工件的2级孔时设计和采用了多齿盘定位分度的半自动夹具,用于双面四轴金刚镗床2A715上(图2)。经实践使用证明,分度准确,动作可靠;在工件一次安装中完成粗精镗工序,精镗余量小且分布均匀,加工精度和光洁度均达到产品技术要求;生产率高,能作半自动工作循环,适用于大批大量生产。现介绍于下:
I plant in the boring of the workpiece as shown in Figure 1 2-hole design and the use of a multi-gear positioning indexing semi-automatic fixture for two-sided four-axis diamond boring machine 2A715 (Figure 2). The practice shows that the indexing is accurate and the operation is reliable. The roughing and boring process is completed once the workpiece is installed. The fine boring allowance is small and distributed evenly. The machining precision and finish meet the technical requirements of the product. The production rate is high and can be semi-automatic working cycle , Suitable for a large number of mass production. Now introduced in the next:
