法兰盘加工工艺及夹具设计详解.doc

法兰盘加工工艺及夹具设计 Abstract Technology is the study of machining fixture design technology and technology-based disciplines, with a very practical, requiring close contact with the learning process should be productive practice, but it also has a strong and comprehensive. The issue is the graduation of flange and fixture design process, the following key elements: First, the analysis of parts, mainly the role of parts, structural and process analysis, part by part analysis to understand the basic situation, The process analysis to know the machining surface and machining requirements. According to the specific part drawing processing requirements, to determine the manufacture of blank forms and dimensions. The second step, the choice of the base surface to determine the processing of coarse and fine reference base. According to the chosen benchmark, the development process route programs, usually two or more of the process line development program, through the process of comparative analysis of the program, and then determine the geometry can make the part shape, size and location accuracy of a reasonable accuracy and other technical requirements programs to ensure the process route. The third step, according to process routes have been identified, select the processing equipment and process equipment, and then determine the amount of each process step of cutting and time fixed for the rough. The fourth step, the design process Ⅶ - 4mm Flange drilling inclined holes of the fixture. To present the fixture design task, select locating datum, and then determine the fixture structure solution, and then began cutting force, clamping force calculation and analysis of positioning error. Finally, the process of finishing the entire design specifications and drawings for the design, bringing the whole design is basically completed. Keywords: Flange; Processing Technology; Fixture Design. 第1章 绪论 1.1机械加工工艺的发展现状 随着机械制造业的发展和科学技术的进步，机械制造工艺的内涵和面貌下不断发生变化，近一二十年的技术进展主要表现在以下几方面： （1）
