摘要

主轴箱体是车床的关键零件之一，通过对CA6140箱体主轴箱体的工艺工装设计，进行铣、镗、钻三副夹具设计，工艺工装设计直接影响主轴箱体的加工质量。通过对主轴箱体的工艺分析，确定毛坯尺寸。根据毛坯尺寸和主轴箱体所需要的加工精度，进行机械加工工艺过程卡的设计。查阅各种文献确定各道工序尺寸，选择其中的铣、镗、钻三副夹具进行设计。

Abstract

the main spindle box is one of the key parts of lathe, through to the CA6140 box equipment design of spindle box of milling, boring, drilling and three pairs of fixture design, Process  equipment design directly affect the quality of the spindle box processing.Through the analysis of the technology for the spindle box, determine the blank dimensions.According to the blank dimensions and the machining precision of the spindle box body need, for the design of the machining process card.Refer to all kinds of documents to determine each working procedure dimension, the choice of milling, boring, drilling and three pairs of fixture design.
