随着科学技术的进步和生产的发展,国民经济各部门要求机械工业不断提供先进技术装备和研究产品品种,这就促使机械工业的生产形势发生了显著的变化。原来以用夹具为主的传统生产技术准备工作的方式,就远远不能适应当前机械工业所面临的新形势。这就提出了多品种小批量生产的夹具设计和研究的课题。
首先介绍了零件的作用,对零件进行工艺分析。然后进行工艺规程设计包括确定毛坯的制造形式、基面选择、制定工艺路线、确定机械加工余量、工序尺寸及毛坯尺寸、确定切削用量及基本工时。最后再进行夹具设计Along with the progress of the science and technology and the development of the production, the various branches and sectors of the National Economy request the mechanical industry unceasingly to provide the vanguard technology equipment and the research attainment product variety, this urged the production situation of the mechanical industry to have a remarkable change. By far, the original way by the unit clamp primarily tradition production technology preparatory work, cannot adapt the new situation which the curre
