车床套工艺及夹具设计
摘 要
工艺学是以研究机械加工工艺和夹具设计为主的一门学科，具有很强的实践性，要求在学习过程中应紧密联系生产实践，同时它又具有很强的综合性，
本次毕业设计的课题是车床套加工工艺规程的制定及后三道工序专用夹具设计，主要内容如下：
首先，对零件进行分析，主要是零件作用的分析和工艺分析，通过零件分析可以了解零件的基本情况，而工艺分析可以知道零件的加工表面和加工要求。根据零件图提出的加工要求，确定毛坯的制造形式和尺寸的确定。
第二步，进行基面的选择，确定加工过程中的粗基准和精基准。根据选好的基准，制订工艺路线，通常制订两种以上的工艺路线，通过工艺方案的比较与分析，再选择可以使零件的几何形状、尺寸精度及位置精度等技术要求得到合理的保证的一种工序。
第三步，根据已经选定的工序路线，确定每一工步的切削用量及基本工时，并选择合适的机床和刀具、量具。对于粗加工，还要校核机床功率。
最后，经过多方面的考虑，设计了后三道工序的专用夹具，即两套钻模和一套铣台阶面的铣床夹具。先提出设计问题，再选择定位基准，然后开始切削力、夹紧力的计算和定位误差的分析。然后把设计的过程整理为图纸，并编写说明书。
通过以上的概述，整个设计基本完成。

LATHER SET'S TECHNOLOGY AND FIXTURE DESIGN
ABSTRACT
A specialized main specialized course that " mechanical manufacturing engineering is studied " is machinery , rely mainly on studying machining technology and jig to design technological discipline , have very strong practicality , require that should contact production practices closely in the learning process, at the same time it has comprehensive the very strong one,
The topic of this graduation design is the lather set establishment and empress that processes craft regulations three work preface appropriation tongs designs, the main contents is as follows:
First of all, analyze ， it is mainly analysis of the function of the part and craft analysis to the part , through part analyze can find out about basic situation of part, and craft analyze may know the processing surface of the part and is it require to process. The processing demand put forward according to the part picture, confirm the manufacture form of the blank and sureness of the size.
The second step, carry on the choice the base ， confirm thick datum and precise datum in the processing course. According to the datum chosen ， make the craft route , usually make the craft route of more than two kinds, with analyzing through the comparison of the craft scheme, and then choosing be able to make such specification requirements as the precision of geometry form , size of the part and precision of position ,etc. get a kind of process of the rational assurance s.
The third step, according to the already selected process route, confirm for every steps of cutting consumption and basic man-hour ， choose suitable lathe and cutter. To rough machining ， will check the power of the lathe .
End, pass by various of consideration, after designing three appropriation tongses of work prefaces, namely two sets of miller tongses that drill the mold and a set of Xian step noodles.Put forward the question of designing first ， and then choose to orient the datum , then the calculation that begins to cut strength , clamp strength and analysis of the localization error. Then put the design course in order as the drawing.
Through the summary of the above, design and finish basically entirely.
