A1支架1零件图
摘要
经过两年多对机械知识的学习，基于自己所学的机械设计、机械制图等课程，本人对支架加工工艺及加工过程中钻铣所用到的夹具进行设计，其中包括公差配合、切削机床等多方面相关知识。
本设计主要对支架工艺规程铣底面和宽24键槽的夹具进行设计。本人将整个设计过程分为三部分:第一本分对零件加工工艺设计；第二部分对零件加工工序进行设计；第三部分是对专用夹具进行设计。在整个设计工程中，对零件分析并选定加工基准，了解其结构是第一步，然后设计出工艺路线。下一步，对零件各个尺寸进行精确计算，根据计算结果选择切削设备以及切削用量，同样根据计算出的尺寸选出夹具的组成部件，例如与机床连接部件等其他部件；通过计算误差分析设计的可行性。
关键词:切削用量；夹紧；误差

After more than twoyears of mechanical knowledge, the course of mechanical design, their school of mechanical drawing based on fixture, drilling and milling used to support my machining process and machining process design, including tolerances, cutting machine tools andvarious related knowledge.
This design is mainly designed for the bracket process specification, the milling bottom surface and the 24 key slot jigs. I divide thewhole design process into three parts: the first part is the design of parts processing technology; the second part is the design of parts processing procedure; the third part is the design of special fixture. In thewhole design project, it is the first step to understand the structure of the parts and select the processing datum, and then the process is designed. Next, on the part of each size accurately calculated according to the calculation results, selection of cutting equipment and cutting parameters, the same according to the calculated size of selected parts of the fixture, such as machine connecting parts and other components; through the calculation and analysis of feasible design error.
Keywords: cutting amount; clamping; error
