机油泵壳类零件加工工艺及夹具设计（含CAD图纸）.zip

摘 要 机油泵壳类零件加工工艺及钻床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：工艺，工序，切削用量，夹紧，定位，误差I 机油泵壳类零件加工工艺及夹具设计年月日 II 摘要机油泵壳类零件加工工艺及钻床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: 工艺,工序,切削用量,夹紧,定位,误差 III Abstract Oil pump shell parts processing technology and drilling fixture design is the design of process design, including machining process design and fixture three. In process design should first of all parts for analysis, to understand part of the process to design blank structure, and choose the good parts machining datum, design the process routes of the parts; then the parts of each step in the process to the size calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure design; then the special fixture, the fixture for the ponents of the design, such as the connecting part positioning devices, clamping element, a guide element, fixture and machine tools and ponents; positioning error calculated by the analysis of fixture, jig structure the rationality and the deficiency, pay attention to improving and will design. Keywords: process, cutting dosage, clamping, positioning IV 目录摘要........................................................................................................................................
