摘 要
这次毕业设计我设计的课题是左支座零件加工工艺及夹具设计。该零件结构简单，体积小。为了提高生产效率和降低劳动强度，专门设计一系列专用夹具。本设计说明书可分为三部分：
第一部分为机械加工工艺规程的编制，简要的分析了零件作用及其工艺情况对毛坯的制造、加工基准进行选择并制定工艺路线，确定机械加工余量，工序尺寸及切削用量等。
第二部分为钻夹具设计和铣夹具设计。夹具设计是本次设计的主要内容之一。在设计中需对夹具的误差进行分析，还要对夹紧力进行计算，以保证满足加工要求。
第三部分为总结及本设计的相关的参考文献。

Abstract
The graduation project I designed the issue is left bearing parts processing technology and fixture design. This part is simple structure, small size. In order to improve production efficiency and reduce labor intensity, designed a series of special fixtures. The design specification can be divided into three parts:
The first part is the preparation of the machining process, a brief analysis of the part and its process on the blank manufacturing, machining datum selection and development of process routes, determine the machining allowance process size and cutting.
The second part the drilling fixture design and milling fixture design. Fixture design is one of the main content of the design.Fixture error analysis is required in the design, but also the clamping force is calculated to meet the processing requirements.
The third part is summarized and the design references.

Abstract
This graduation design I design issue is left bearing parts processing technology and fixture design. This part has simple structure, small volume. In order to improve production efficiency and reduce labor intensity, specially designed a series of special fixture. The design specification can be divided into three parts: the first part of the preparation of
for mechanical machining, a brief analysis of the parts and manufacturing, machining process reference to blank selection and formulation process, determine the machining allowance, size and cutting processes consumption.
第二部分为钻夹具设计和铣夹具设计。 Fixture design is one of the main contents of the design.In the design of the jig to the error analysis, and calculated the clamping force, in order to meet the processing requirements.
third part is summary and related references for the design of the. Keywords:

Summary
this graduation design I design issue was left bearing parts machining and fixture design. The part has a simple structure, small size. In order to improve efficiency and reduce labor intensity and designed a series of special fixture. The design specification can be divided into three parts:
part machining process of preparation, provides an analysis of parts and processes to select the rough manufacturing, processing benchmarks and develop routes to determine stock allowance, size and cutting operations.
Second part fixture for fixture design and milling. Fixture design is one of the main elements of this design.Required an analysis of the error of the jig in the design, but also to calculate the clamping force to ensure processing requirements are met.
Third part summary and references relating to this design.
