Abstract
The main significance of the papers is to overally introduce the under pressure-group-drilling fixture and do a specific and detailed descriptionits to its important components of the positioning of mechanical components, clamping device designed. Analysize the state and development trend of the domestic and overseas manufacturing technology developed into a group , simply introduce the theory and composition of drilling fixture,making group technology as the core idea, classify the parts of the productiong according to shape the structure and function, Similar to the shape and size similar to the processing elements and installation of the same components singled out to form the group needed to process groups, according to the group of co-ordination to consider the design of a fixture fixture structural design, by the end make positioning error analysis of the group Fixture. Finally, provide the fixture engineering drawings. Through the design of the under pressure-group fixture of the drilling module designed ,address the practical problems of the group-processing projects, but also laid a good foundation for the future in the mechanical design and manufacturing work.
