转换套机械加工工艺及铣63侧面夹具设计
摘要
本次的设计课题为转换套零件加工工艺以及其铣床夹具设计。在这次的整个过程中，主要的内容包括利用到了制图软件进行有关图形的绘制、工艺规程设计、专用夹具设计以及包括文字编写排版等过程。设计过程首先，先对转换套这个零件的结构和作用分析，主要是分析零件的作用以及转换套零件加工工艺分析。从而了解它的工艺方面。通过了解转换套零件的结构以及工艺分析可以得出选择毛坯的材料以及制作毛坯的形式。制作毛坯的过程要按照转换套零件的结构特点进行。接下来是进行设计机械加工工艺路线，进行定位基准分析以及选择。确定加工的粗基准以及精基准。进行工艺路线的制定，一般制作几条工艺路线规程然后进行挑选最为合适的一条。适合包括路线的加工精度、制作成本以及加工效率等方面。而且要制作一个合理的专用夹具，本次制作的专用夹具主要是用于转换套钻孔加工，夹具的设计结构方面。要做到结构简单，便于操作。

Abstract：
Part of the preparation processing, in processing machinery occupies very important position, part process system is reasonable, which is directly related to the final part quality requirements can be met; fixture design is an indispensable part of, it is related to can improve the efficiency of the problem. Therefore both in the mechanical processing industry is a vital link.In machine tool of mechanical parts of the process, in order to ensure the processing precision of the workpiece, first of all to guarantee the workpiece holds the correct position on the machine, then by clamping the workpiece in the correct position is fixed, this task is by the machine tool fixture. For single and small batch production, the use of universal fixture should be as far as possible, so that the production cost of the workpiece can be reduced. But because the universal fixture is suitable for various workpiece clamping, so clamping tend to spend more time and the operation is complex, the production efficiency is low, it is difficult to guarantee machining accuracy, so it is necessary to design a special fixture.The design content involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance and measurement and other aspects of knowledge.
