摘  要

本设计上壳体零件加工过程的基础上。主要加工部位是平面和孔加工。在一般情况下，确保比保证精密加工孔很容易。因此，设计遵循的原则是先加工面后加工孔表面。孔加工平面分明显的阶段性保证粗加工和加工精度加工孔。的基础上，通过输入输出底面作一个良好的基础过程的基础。主要的流程安排是支持在定位孔过程中的第一个，然后进行平面和孔定位技术支持上加工孔。整个过程是一个组合的选择工具。专用夹具夹具的选择，有自锁机构，因此，更高的生产力，对于大批量，满足设计要求。

Abstract

Based on this design process of shell parts. The main processing part is plane and hole machining. In general, it is easy to ensure precision machining holes than guarantee. Therefore, the design principle is the first processing surface after machining hole surface. Phase plane hole machining obvious to ensure the accuracy of machining and rough machining hole. On the basis of the foundation, through the input and output of the bottom surface as a good basis for the process. The main process is supported in the positioning hole in the process of the first, and then the processing hole plane and hole positioning technology support. The whole process is a combination of selection tool. Special fixture fixture selection, a self-locking mechanism, therefore, higher productivity, in large quantities, meet the design requirements.
