目前在一般工厂中,心轴的使用极为普遍且结构简单,但往往不受设计、制造和使用者的重视,因而造成某些生产上的薄弱环节,尤其是最终精加工和最终检验所使用的心轴。今就我厂某些心轴设计和使用中存在的问题综述如下。一、心轴夹紧螺纹的制造工艺带有花键孔齿轮用滚齿心轴,以其锥面及带有螺纹端的中心孔与滚齿机联接。原工艺的心轴为整体淬火,以其中心孔为基准磨削锥面、外圆,而螺纹部分
At present, the use of mandrels in general factories is extremely common and simple in construction, but often unaided by design, manufacture and users, resulting in some manufacturing weaknesses, in particular the final finishing and final inspection Spindle. Now my factory some mandrel design and use of existing problems are summarized below. First, the mandrel clamping thread manufacturing process with spline hole gear with hobbing mandrel, with its tapered surface and the threaded end of the center hole and hobbing machine connection. The original process mandrel quenching the whole, with its center hole as the base grinding cone, cylindrical, and the threaded part
