压滚座
压滚座的工艺规程及钻Φ9孔的工装夹具设计
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。
压滚座的工艺规程及钻Φ10孔的工装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。
ABSTRCT
The design of the content relates to the machinery manufacturing technology and machine tool fixture design, metal cutting machine tool, tolerance and measuring and other aspects of knowledge.
The roller seat of procedure and drill a9 hole jig design is including machining process design, process design and fixture design in three parts. In the design process should first of all parts for analysis, to understand the parts of the process to design a rough structure, and choose the good parts processing base, design parts of the process route; and then thevarious parts of the process step size calculation, is the key to decide the process equipment and cutting parameters; then special fixture design, selection and design of a jig for thevarious components, such as positioning devices, clamping elements, a guide element, clamp and the machine tool connecting parts and other components; calculate fixture is producedwhen the positioning error analysis, fixture structure rationality and deficiency, and later in the design of improved.
Keywords: process, process, cutting dosage, clamping, positioning, error.
