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。

Abstract
Pump is a very important and widely used parts in mechanical products, such as Gasoline

pump, variable frequency pump, hydraulic pump, submersible pump, diaphragm pump, power

steering pump, double action vane pump, etc.Its role cannot be replaced by other parts,

and therefore I choose the pump cover closely related to the pump as the design theme. In

the design process of I refer to related process books material, comprehensive comparison

finally chooses the best design. Hydraulic pump cover is one of the important parts in

hydraulic pump. Using the drilling, expanding, milling and other traditional techniques,

is not only low efficiency, and poor stability. It’s difficult to ensure the accuracy and

restrict the production development. Using a combination of machine parts in large

quantities is the development direction of machining, because it’s efficient and high

productivity. This design includes the design of the hydraulic pump cover process

planning; the main problems of the Hydraulic pump cover processing and the measures to be

taken in the Process Design. There is a specific determining blank obtained manufacturing

form, the selection of base, process route determination, machining allowance, process

dimension and the rough determination cutting specifications and so on. In addition, I

design the special fixture for hydraulic pump cover, and made a brief description of the

fixture operation. Thanks for the great help given by students to teachers in the design.

Key words: Hydraulic Pump Cover; Process; Fixture Design
