摘 要
零件的加工工艺编制,在机械加工中占有非常重要的地位,零件工艺编制得合不合理,这直接关系到零件最终能否达到质量要求;夹具的设计也是不可缺少的一部分,它关系到能否提高其加工效率的问题。因此这两者在机械加工行业中是至关重要的环节。
这次设计主要经历了两个阶段:第一阶段是机械加工工艺规程设计,第二阶段是专用夹具设计。
通过对C6150 主轴箱体零件图的分析及结构形式的了解,从而对主轴箱体进行工艺分析、工艺说明及加工过程的技术要求和精度分析。然后再对主轴箱体的底孔、轴承孔的加工进行夹具设计与精度和误差分析,该工艺与夹具设计结果能应用于生产要求。
通过此次设计,使我们基本掌握了零件的加工过程分析、工艺文件的编制、专用夹具设计的方法和步骤等。学会了查相关手册、选择使用工艺装备等等。

Abstract
Preparation of parts of the processing technology, processing machinery occupies a very important position, part preparation process was reasonable, which is directly related to the final part quality requirements can be met; fixture design is an indispensable part, it is related to whether can improve its processing efficiency problem. Therefore, both in the machining industry is a very important link.
This design mainly experienced two stages: the first stage is the machining process planning, the second stage is the special fixture design.
Based on the C6150 spindle box parts diagram analysis and the structural form of understanding, thus the spindle box for process analysis, process explanation and analysis the technical requirement and the precision. Then the spindle box bottom, bearing hole processing fixture design and precision and error analysis, the craft and the jig design results can be applied to production requirements.
Through this design, we mastered the basic parts of the process analysis, process documentation, special fixture design methods and steps. Learn to check the relevant manual, choose to use the technology and equipment and so on..
Key Words: Processing, fixture design, machine tool, analysis
