摘要
本次设计内容涉及了机械制造工艺及机床夹具设计、金属切削机床、公差配合与测量等多方面的知识。
杠杆加工工艺及钻Φ8孔夹具设计是包括零件加工的工艺设计、工序设计以及专用夹具的设计三部分。在工艺设计中要首先对零件进行分析,了解零件的工艺再设计出毛坯的结构,并选择好零件的加工基准,设计出零件的工艺路线;接着对零件各个工步的工序进行尺寸计算,关键是决定出各个工序的工艺装备及切削用量;然后进行专用夹具的设计,选择设计出夹具的各个组成部件,如定位元件、夹紧元件、引导元件、夹具体与机床的连接部件以及其它部件;计算出夹具定位时产生的定位误差,分析夹具结构的合理性与不足之处,并在以后设计中注意改进。
关键词:杠杆、工艺规程、切削用量、夹具设计
Abstract
This design content has involved the machine manufacture craft and the engine bed jig design, the metal-cutting machine tool, the common difference coordination and the survey and so on the various knowledge.
Lever processing technology and drill hole jig design is the design of Φ 8 include part machining process design, process design and fixture thre. In process design, analysis of the part must first understand the parts of the process re-engineering the structure of a blank, and select a good part of the processing of the base to design parts process route; followed by the various working steps on the part of the procedures for the size of the calculation, the key is to determine the various stages of work out of process equipment and cutting consumption; then dedicated fixture design, selection of design out of all the component parts fixture, such as the positioning components, clamping components, guiding elements, the specific folder connection with the machine parts and other components; calculate the positioning fixture positioning error generated, analysis fixture structure is reasonable and deficiencies, and attention to improving the design in the future.
Keywords: lever、Process planning、cutting parameter、grip design
