前言

泵盖的主要作用是密封、紧固。保证油泵正常工作，不漏油，不与齿轮轴打齿。

因此，泵盖要具有很好的伸缩性以及较好的对准性。该零件的工作表面主要是右端面、孔的定位以及配合问题。泵盖的加工工艺的可行性关于到该零件的质量以及生产成本问题。

设计任务书

1、总体介绍：设计包括CAD与CAM两大模块，重点在于CAM。

2、具体要求：根据平面图建模，并对该零件上所有能够铣、钻的表面进行加工。完成指定题目的设计后，要求每人编写说明书一份（包括封面、目录、设计任务书、正文、设计心得与体会、参考资料等七部分，可以打印，请上交前自己检查是否缺项）。同时上交电子稿与相应prt文件。

正文应包括：零件的建模过程、毛坯的建模过程、零件工艺分析与编制的工艺过程、具体加工过程（每个操作的创建详细过程，要求说明各个参数是如何配置的、每个操作生成的刀轨）、车间工艺文档
