In the design process of I refer to related process books material, prehensive parison 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 bination 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.
