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.
