摘 要

 

本设计专用夹具的设计本设计专用夹具的设计阀盖零件加工过程的基础上。 主要加工部位可以说是平面和孔加工。在一般普通情况下，确保比保证精密加工孔更加容易。 原以此，设计遵循的原则是先加工面后加工孔表面。 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取工具。 专用夹具夹具的选取，有自锁机构，原以此，更高的生产力，对于大批量，达到设计给定的要求。

My design is the angle gear seat parts machining process and special fixture design process design based on self. The plane and a series of hole is the main processing surface of the part. As is usually the case to do so. The accuracy of the flat surface to machining accuracy than holes easier control. We can draw. My design on the surface after the first hole sequence. Datum selection to the supporting hole seat angle gear input shaft and the output shaft as a rough benchmark. Main processes arrangements to support holes for positioning and processing the top plane.The bottom surface and the two holes as a precision technology base. I hereby use coordinate boring to make processing of bearing hole. Combination machine tool throughout the machining process design. Special fixture I use, its structure can not be locked, so we can get high production efficiency, I design suitable for processing large quantity, on the assembly line.
