摘要
本文主要介绍了桥壳总成的相关知识，根据桥壳总成的结构和特点，在进行专门研究的基础上制订出该部件的加工工艺路线，选择、计算各工序主要参数及选出加工设备，填写加工工艺规程，设计针对该构件的专用夹具。
在确定了桥壳总成初步设计方案后，决定采用传统理论方法对桥壳总成的结构进行设计、计算，并采用AutoCAD设计软件对桥壳总成、夹具、进总装图等行了工程绘图。而后又对桥壳总成的工艺规程进行了编排；在查阅了大量关于桥壳总成设计的书籍后，确定桥壳总成的设计方案，绘制了桥壳总成夹具装配图，给出了桥壳总成工艺规程的说明书，并对整个设计进行系统分析，得出整个设计切实可行。

Abstract
This paper describes the axle housing assembly of the relevant knowledge, according to Shell assembly of the bridge structure and characteristics in the field on the basis of the developed parts of the processing line, choose to calculate the main parameters of the processes and equipment, fill out the processing Of a point of order, designed for the dedicated members of the fixture. In determining the bridge shell assembly preliminary design options, decided to adopt the traditional theory of the bridge shell assembly and structure of the transmission system design, calculation, the intensity of checking and use of AutoCAD design software to bridge shell assembly, fixture, The General Armament Department plans to carry out the engineering drawings. Shell on the bridge and then the assembly of a scheduling order in check a large number of shell assembly on the bridge design books, determine the design of the bridge shell assembly programme, rendering the bridge shell assembly fixture assembly, are given Bridge shell assembly process of order brochures, and the design of systems analysis, that the whole design practical.
