梅花轴是机械中用来传递力和扭矩的零件。图1所示的这种梅花轴外径很大,且梅化部分长,为了按时完成生产任务,保证产品质量,我们采用了新的加工方法,具体措施如下; 1.工艺 我们采用锯切-车削-划线-钻削的加工工艺流程。从图1中我们可以看到,梅花孔圆心正好在梅花轴的外径处,因此,我们可以将 Plum shaft is the mechanical parts used to transmit force and torque. The plum blossom shaft shown in Fig. 1 has a large outer diameter and a long plumification part. In order to accomplish the production tasks on time and ensure the product quality, we adopt a new processing method as follows: 1. Process We adopt sawing - Turning - crossed - drilling process of processing. From Figure 1, we can see that the plum blossom hole center just at the plum shaft diameter, so we can
