摘要
大齿轮毂作为机车上重要配件,对其加工精度有较高的要求,尤其是54°方向上注油孔,对其位置和方向的控制成为重点内容。由于对角度的要求较高,人工难以保证达到要求的精度,况且在批量生产中不利于提高生产效率、降低次品率,故选择做一工装,将对产品的精度要求转换成对工装的要求。
Large gear hub as an important part of the locomotive.It has high requirements on the processing accuracy,especially in the direction of 54 ° injection hole,and its position and direction of control become the key content.Due to the higher requirements of the angle,it is difficult to ensure the required accuracy by men,Moreover,in mass production,it is not conducive to improve production efficiency and reduce the defective rate,so choosing to do a tooling,the product will be converted into precision requirements of the tooling requirements.
