十字沟槽零件的钻M6螺纹夹具设计及加工工艺装备含4张CAD图+说明书

夹具装配图

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。
十字沟槽零件的工艺设计、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：切削用量;夹紧;定位;误差。

Abstract
The design involves the mechanical manufacturing process and machine tool fixture design, metal cutting machine tools, tolerance and measurement, and other aspects of knowledge.
The processing regulations for the connection parts of hydraulic pipe fittings and the three parts of process design, process design and special fixture design for drilling 3 holes and expansion and hinge 10 are introduced. In the process design, the parts are analyzed first, the process of the parts is redesigned and the structure of the blank is redesigned. The process datum of the parts is selected and the process route of the part is designed. Then the size calculation of the working procedure of the parts is calculated, the key is to determine the process equipment and the cutting amount of the various working order; then, the key is to determine the amount of the process equipment and the cutting amount. The design of the special fixture is carried out, and the components of the fixture are designed, such as the positioning element, the clamping element, the guiding element, the connecting parts with the machine tool and the other parts. The positioning error is calculated when the fixture is positioned, and the rationality and inadequacies of the fixture structure are analyzed, and the design is injected in the future. It is intended to be improved.
Key words: Cutting dosage;clamp;Location; error.
