轴承座加工工艺及车大孔夹具设计（有CAD图纸）.pdf

XX 0 1 Abstract A parts processing technology and fixture design of the bearing is designed to include part machining process design, process design and fixture three. In the process of design should first carries on the analysis to the components, parts of the process to understand the design of the structure and the choice of blank, processing base part, design part of the process route; and then on the part of every step of process dimension calculation, the key is to determine the craft equipment and the cutting dosage of each working procedure design; then the special fixture, fixture for the various components of the design, such as the connecting part positioning device, clamping device, a guide element, fixture and machine tools and other components; the positioning error is calculated when the fixture, analysis of the rationality and deficiency of fixture structure, pay close attention to the improvement and design in later.
