支承套零件加工工艺及钻孔夹具 毕业设计/毕业论文/课题报告 - 工

高效率、高精度加工是数控机床加工最主要特点之一。利用数控机床加工，其产品加工的质量一致性好，加工精度和效率均比普通机床高出很多，尤其在轮廓不规则、复杂的曲线或曲面、多工艺复合化加工和高精度要求的产品加工时，其优点是传统机床所无法比拟的。
本课题对异性体、复杂的曲线、多工艺复合化加工进行探索，设计出三种切实可行的工艺流程及工艺装备。本文通过分析支承套的结构特点和加工要求，制定了一套较合理的夹具设计，从而为保证该零件的加工精度将提供一种经济实用的工艺装备，具有一定的实用价值。通过对各种定位夹紧装置的分析比较，选择并组合了一套既能够满足加工要求的，又比较简洁的装置，并对各工步进行数控编程。

Abstract

High-efficiency and high accuracy's process is a number to control tool machine to process one of the most characteristicses.Make use of the number controls tool machine to process, its product process of quality consistency good, process accuracy and efficiency all a higher than common tool machine is a lot of, particularly at the outline irregular and complicated curve or the curved face, many the craft compound turn to process the product which requests with high accuracy to process, its advantage is a traditional tool machine to can't compare to.
This topic turns to process to carry on quest to the opposite sex body, complicated curve, many craft compound and design three kinds of practical viable craft processes and craft material.This text passes the analysis structure characteristics which accepts a set with process a request, drew up a set of more reasonable tongs design, thus for promise that process of spare parts accuracy will provide a kind of economic practical craft material and have certain practical value.Pass the analysis comparison to clip the tight device to various fixed position, choose and combined 1 set since can satisfy to process a request of, again more simple and direct device, and carry on to each work step number control plait distance.
