齿轮泵泵体的加工工艺与专用夹具设计
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。
泵体加工工艺规程及其钻孔的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
Gear pump body process and special fixture design
Abstract
The design involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance, coordination and measurement, and many other aspects of knowledge.
Pump processing technology and drilling fixture design, including parts processing, process design, process design, and the design of special fixture three parts. In the process of design should first understand the analysis of parts, parts of the process to design a blank structure, and choose the ponents the processing datum, designs the process routes of the parts; then the parts of each labor step process size calculation, is the key to decide the craft equipment and the cutting process of the various design parameters; then a special fixture, the fixture selection for the ponents of the design, such as connecting parts positioning elements and clamping elements, guide element, fixture and machine tool and ponents; positioning error is calculated when the fixture, analysis the rationality and ing of fixture structure, improve and design in later.
Keywords: process, process, cutting parameters, clamping and positioning
