在脱粒机生产中,需要大量的弓形齿,其半成品如图1。为了适应生产的需要,我们制造了一台机械控制双向年削的鼓轮机床。除上料靠人工外,其它动作都是自动的。具有结构简单,制造成本低,生产效率高,大大减轻劳动强度等特点。现将机床结构简介如下: In the threshing machine production, the need for a large number of arched teeth, the semi-finished products shown in Figure 1. In order to meet the needs of production, we have manufactured a drum machine controlled by machine. In addition to the material by artificial, other movements are automatic. The utility model has the characteristics of simple structure, low manufacturing cost, high production efficiency, greatly reducing labor intensity and the like. Now the machine tool structure is as follows:
