我厂没有专用花键轴铣床,花键轴全在万能铣床加工。过去先用双刀把14毫米宽(图1)凸键铣好,然后用薄铣刀把剩下的三角形分5～6刀铣成φ54。为了提高效率和质量,我们搞一个磨成型R刀小胎具,用R刀把剩下的三角形一刀铣掉,现介绍如下。一、胎具结构1.公转部分:公转轴9(图2)下部装在底座孔里,能自由转动。滑板4装在公转轴9上部凹槽中,上有压 I do not have a dedicated factory spline shaft milling machine, spline shaft milling machine universal milling. In the past the first 14 mm wide with a double-convex (Figure 1) convex key milling good, and then use a thin cutter to the remaining triangles 5 ~ 6 knife milling φ54. In order to improve the efficiency and quality, we engage in a small tool R shaped grinding knife, R knife to the other side of the triangle milling, are described below. First, the tire structure 1. The revolution part: revolution axis 9 (Figure 2) The lower part installed in the base hole, can rotate freely. Slide 4 mounted on the shaft 9 upper groove, there is pressure
