右支架座零件

摘要
夹具设计对每一个理工科学生而言都是必不可少的，夹具的设计和研究为今后的学生和工作将提供很大的帮助。
本文设计的任务是右支架座零件的加工工艺分析及其扩2-Ф43.5孔的夹具设计。在充分了解零件的结构后，对其毛坯尺寸、制造类型、基准、加工的工艺路线进行了确定；然后依据设计的加工工艺路线，对每一个工序进行计算。
本次设计扩2-Ф43.5孔专用钻床夹具，在减少停机时间的同时，还提高生产效率。在进行该专用夹具设计的时候，首先应该是建立在对零件的工艺进行分析、选择粗精基准、进行必要计算的基础上，对所要加工的工序做好定位基准的选择，对夹具中的切削力及夹紧力做出计算。计算出夹具定位时产生的定位误差，分析夹具结构的合理性与不足之处，并在以后设计中注意改进。

Abstract
Fixture design is indispensable for every science and engineering student. Fixture design and researchwill provide great help for future students andwork.
The task of this paper is to analyze the processing technology of the right bracket seat parts and to design the fixture for expanding 2-Ф43.5 holes. After fully understanding the structure of the parts, the blank size, manufacturing type, benchmark and processing route are determined, and then each process is calculated according to the designed processing route.
This design expands 2-Ф43.5 hole special drilling fixture, reduces downtime, but also improves production efficiency. In the design of the special fixture, first of all, it should be based on the analysis of the process of the parts, the selection of rough and precise benchmarks and the necessary calculation, the selection of positioning benchmarks for the processing procedures, and the calculation of the cutting force and clamping force in the fixture. Calculate the positioning errorwhen fixture is positioned, analyze the rationality and shortcomings of fixture structure, and pay attention to improvement in future design.
Keywords: right support base; fixture design; process route; positioning datum; cutting force
