摘要
为车床上加工液压泵上体3个阶梯孔设计夹具,此夹具是一种安装在花盘上的直线移动式车床专用夹具。分析夹具的结构特点、工作原理,计算其定位误差和夹紧力,进行加工精度分析,该夹具能保证三孔中心尺寸精度、三孔轴线与底面垂直精度以及与四小孔位置精度。
The jig was designed for processing three trapezoid holes of upper hydraulic pump in lathe. It was a kind of special linear motion type jig fixed on the panel. The ＂configuration features, operating principle of this jig were analyzed, positioning error and pinch force were calculated and machining accuracy was analyzed. The size precision of three-hole core, perpendicular precision between three axes and bottom surface, positioning precision of four holes can be assured by this jig.
