CA6140车床主轴法兰加工工艺和3-Φ12孔的夹具设计
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。
CA6140车床主轴法兰加工工艺规程及专用钻床夹具的设计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。

Abstract
This design involves mechanical manufacturing technology and machine tool fixture design, metal cutting machine tools, tolerance fit and measurement and other aspects of knowledge.
The design of the design of the fixture for the machining of the spindle flange of the CA6140 lathe is three parts, including the process design, the process design and the design of the special fixture. 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 theworking procedure of the parts is calculated, the key is to determine the process equipment and the cutting amount of thevariousworking 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 partswith the machine tool and the other parts. The positioning error is calculatedwhen 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.
Keywords: CA6140 lathe spindle flange, fixture design, process route
