为了车削图1所示的凹形鼓轮,我们自行设计制造一套设备(图2),用该设备加工鼓轮,不仅提高了生产效率,而且保证了质量。简介如下。一、结构原理如图2,在车床三爪夹头2上装夹一个盘形凸轮靠模5,并在盘形凸轮靠模内装定位拔杆7,以带动凹形鼓轮8转动。鼓轮8安装在凸轮靠模心轴12上,由螺帽11通过套筒9把其紧固在心轴12上。活动顶针13及尾座14顶住心轴12的一
To turn the concave drum shown in Figure 1, we designed and manufactured a set of equipment (Figure 2). Drums were machined with this equipment, which not only increased the production efficiency but also ensured the quality. Brief introduction is as follows. First, the structural principle shown in Figure 2, in the lathe jaw chuck 2 mounted on a disc-shaped cam by the mold 5, and in the disc-cam cam positioning pull rod 7 to drive the concave drum 8 rotation. The drum 8 is mounted on the cam die mandrel 12 and is secured to the mandrel 12 by a nut 9 through a sleeve 9. The movable thimble 13 and the tailstock 14 are against one of the mandrels 12
