我们设计制造了一种简易分度头装置。在盘、环、法兰、端盖类零件及水泵导流壳和叶轮水力模型导片安放线的划线中,收到了满意的效果。简易划线分度头的结构如图所示,是由支架体、夹紧装置、分度刻度盘、旋转滑动部分及锁紧装置组成。 1.支架体由底盘、立锥体、轴承体经机加工后焊接合成。 2.夹紧装置选用了一个三爪自动定心卡盘。 3.分度盘部分由刻度转盘(主尺)和刻度固定盘(副尺)经机加工和刻度线加工后组成。刻度转盘(主尺)经机加工后,在外缘精确地刻印出360等份,即每等份为1°,分三种刻线长度。刻度转
We designed and manufactured a simple indexing head device. In the disk, ring, flange, end cover parts and pump diversion shell and impeller hydraulic model guide line laying of the line crossed, received satisfactory results. Simple crossed dividing head structure as shown, is by the bracket body, clamping device, indexing dial, rotating sliding part and the locking device. 1. Stent by the chassis, vertical cone, bearing body after welding synthesis. 2. Clamping device selected a three-jaw automatic centering chuck. 3. Indexing plate part by the scale turntable (main ruler) and the scale fixed plate (foot) by the machining and tick processing. Scale dial (main ruler) after machining, engraved accurately in the outer edge of 360 equal parts, that is, each equal to 1 °, divided into three kinds of engraved length. Scale turn
