我厂在生产某工件时,需要在圆柱体上加工一阶梯横孔。由于工件外形不规则,横孔的位置特殊,孔的粗糙度值要求较小,孔壁很薄,造成加工困难。本文经实践解决了工艺、工装和生产中的实际问题,现介绍如下。一、工件结构分析工件材料为LY11—CZ,YB63—66铝棒,在加工横孔之前,工件已被加工成如图1所示的形状和尺寸。用微机计算其重量为166.96g,重心距横孔轴线
I plant in the production of a workpiece, you need to process a horizontal cylinder in the horizontal hole. Due to the irregular shape of the workpiece, the position of the horizontal hole is special, the roughness of the hole is less demanding, and the hole wall is very thin, which causes the processing difficulty. This article has been practiced to solve the practical problems in the process, tooling and production, are presented below. First, the workpiece structure analysis The workpiece material LY11-CZ, YB63-66 aluminum rod, before processing horizontal hole, the workpiece has been processed into the shape and size shown in Figure 1. Calculate the weight of the computer with a computer 166.96g, the center of gravity from the axis of horizontal hole
