轴阶套——A3
摘要
本次设计的题目是轴阶套加工工艺规程制定及钻φ4孔专用夹具设计，在掌握零件作用的基础上，对零件的工艺进行分析。针对设计给定的题目，设计中主要对机床夹具进行设计。本夹具体是以保证加工精度，生产效率和便于工人操作为宗旨展开的设计。
设计之初我查阅相关数据及国内外关于机床夹具的文献，在看懂零件图的同时对零件的结构和工艺进行分析，明确粗基准和精基准的选择，确定零件的加工余量与毛坯的尺寸、从而确定零件的加工工艺过程、计算各工序的切削用量及工时。最终完成了本次设计所需的夹具。
Abstract
The subject of this design is the formulation of processing technology rules for axle step sleeve and the design of special fixture for drilling_4 holes. On the basis of mastering the function of parts, the process of parts is analyzed. In view of the given design topic, the design mainly carries on the design to the machine tool fixture. This fixture body is designed to ensure the processing accuracy, production efficiency and easy operation for workers.
At the beginning of the design, I consulted the relevant data and the literature about machine tool fixture at home and abroad, analyzed the structure and process of the parts while reading the part drawings, made clear the selection of rough and precise reference, determined the processing allowance of the parts and the size of the blank, thus determined the processing process of the parts and calculated the cutting of each process. Dosage and hours. Finally, the fixture required for this design has been completed.
