Abstract

Pump application in mechanical products is very wide, is one of the important parts in particular, its important status is irreplaceable, so I chose the hydraulic pump cover as a graduation design topic. Read the information from the Internet and library search, and consult the guidance of the teacher, I found the design scheme and the best method. Combination machine tool I chose, processing mass components, convenient, fast, can greatly improve the production efficiency, have great prospects for development. The design includes the process design of hydraulic pump cover, analysis of 3D modeling and components parts, and special fixture design. To determine the specific hair embryo size, determination of machining process and machining allowance, and determine the amount of cutting etc..

Keywords: hydraulic pump cover; special fixture; process card; processing technology;
