液压泵盖工艺工装设计 摘要 泵是非常重要的一个零件，广泛应用于机械产品，如汽油泵，泵，液压泵，潜水泵，隔膜泵，动力转向泵，双作用叶片泵，它的作用是不能被其他成分所取代，所以和泵的选择是密切相关的泵盖作为一个设计的主题，来获取过程有关的大量书籍的过程中，最好的设计方案的综合比较与选择。液压泵盖是液压泵重要的零件之一，采用钻、扩、铣等传统工艺,不仅效率低,而且稳定性差,精度不易保证,制约了生产的发展。应用组合机床加工大批量零件，快捷高效，生产率高，是机械加工的发展方向。本设计主要包括液压泵盖的加工工艺过程的设计，应采取哪些措施存在的主要问题和液压泵盖的加工设计过程。具体确定毛坯制造形式获得，基面的选择，确定工艺路线，加工余量的确定，工序尺寸及空白，切削用量的确定。此外，这次还给液压泵盖进行了专用夹具设计，以及夹具操作的简要说明。在完成此次设计任务中得到老师及同学们的大力帮助，在此向他们表示衷心的感谢。 关键词：液压泵盖；工艺；夹具设计 Abstract Pump is averyimporta
