我厂为十二种不同规格的花键滚刀刃磨,设计制成的靠模工具(图1),经生产使用,效果良好。现介绍如下:结构及工作原理:图1中,靠模1和花键滚刀分别滑套和固定在心轴2上,心轴2两端用顶尖顶着。靠模支架3固定在床身上,导向销15插在靠模螺旋槽内。当工作台作往复运动时,靠模1依本身螺旋槽作螺旋运动,并通过分度支架4、分 I plant for 12 different specifications of the spline hob grinding, designed by the model tool (Figure 1), the production and use, the effect is good. Now introduced as follows: Structure and working principle: In Figure 1, the model 1 and the spline hob respectively, and fixed to the mandrel on the mandrel 2, mandrel 2 at both ends with a top against. The mold holder 3 is fixed on the bed, and the guide pin 15 is inserted in the mold spiral groove. When the workbench for reciprocating movement, by the model 1 according to their spiral groove for spiral movement, and through the indexing bracket 4, points
