活动压紧板多孔钻专机设计（有CAD图纸）.pdf

() I II Abstract Application of combined high-volume machining parts, high efficiency, high productivity is the development direction of machining. The topic of this graduation design is the design of special purpose machine - crankcase bottom hole drilling 10-M10 modular machine tool design. Making process in the process, with a mass of bottom hole drilling project, and to seek the best technology solutions, which illustrates the importance of process in the production process. The main content of my design are: the overall layout design of machine tool; on the machine feed and transmission parts of the design; combined with the example, the fixture design; the design, this machine can meet the design requirements, compared with traditional machine, this machine has high automation, high productivity, advantages higher precision. Keywords: combination machine; drill hole; fixture design; manual III II Abstract III 1 1 1.1 1
