设计任务书
原始资料:
被加工零件图一份,小批生产。
Q=2000台/年,
n=1件/台,每日1班。 设计要求: 1.编制技术文件 (1)机械加工工艺过程卡一套 (2)工序卡一套 2.绘制图纸 (1)零件图1张 (2)毛坯图1张 (3)夹具装配图1张 (4)夹具零件图1张 3.设计说明书1份 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 desig
