ABSTRACT
Pump is a kind of important parts, is widely used, such as gasoline pump, hydraulic pump, submersible pump, diaphragm pump and other products, its role in mechanical industry can't be replaced by random, this topic is optional pump cover mechanical processing technology and fixture design, because the pump cover are closely related and pump parts, in the design process, from a large number of relevant books comprehensive compare and choose the best design solution. Hydraulic pump cover is one of the important parts in the machinery industry there is no denying the fact that adopts the traditional process, such as drilling, expanding, and milling, etc., not only low efficiency and poor stability, not easy to ensure accuracy, constrains the development of production, should be used for mass production parts modular machine tool for processing, not only efficient but also the productivity is high, is the best development direction of mechanical processing. Designed by the topic of a given topic, what measures should be taken to solve the pump cover processing design, fixture design and the main problems existing in the process of. Such as blank making form of concrete, the selection of the datum, the process and blank size, the determination of process route, cutting parameter determination. In the process of special fixture design, there are many noticeable problems in design of fixture is accurate and reasonable guarantee the important conditions of qualified parts, fixture design in the operating instructions is also very important. This design can be completed mainly thanks to my teacher and classmates support and help, to express our heartfelt thanks to them.
Key words: process; Fixture design.
