Abstract
The graduation design is the main content of the machining process planning preparation and special fixture design process. I can comprehensive use of mechanical manufacturing technology and other basic curriculum of basic theory and method, in order to be able to complete the turbine speed reducer machining technology and drilling machine fixture design task, the integrated use of knowledge, and apply the correct design method, and developed a turbine speed reducer of the machining process planning. Combine craft design content, skilled in the application process calculation method, the relevant process the content analysis of the correct design and the computation, such as process parameters, cutting force and cutting power, cutting speed, positioning error, clamping force, etc. Through the turbine speed reducer to the processing technology of the determination of the route, the parts processing to the underside as the benchmark is reasonable, the processing technology solutions to meet the basic requirements of basic selection coarse and fine basic selection of the four principles. This fixture for drilling machine use special jig, this fixture is characteristic of the targeted, compact construction, simple operation, high productivity. In this design, the design of the machine tool fixtures meet fixture basic requirements of the overall design, fully guarantee the quality of parts processing, has the high production efficiency and lower cost of manufacture and good structure technology .
Key words: Machining; Process specification; Special fixture; Turbine gear unit housing
