【机械设计制造及自动化专业】【毕业设计+文献综述+开题报告】轴承座加工工艺编制及夹具设计 Abstract The craft establishment of the components, holds the very important status in the machine-finishing, whether the components craft establishes are reasonable or not have a direct relation to the components to achieve the final quality requirement ; The jig’s design is also an essential part. It relates to whether it will improve its processing efficiency or not. Therefore these two in the machine-finishing profession are the very important link. The graduation design topic is the machining process and fixture design of bearing house. The content of the main do have the parts size technology for analysis, to make clearly the main technical parameters of clear parts and precision requirements, etc. Second choice datum and the preliminary worked more than two process route. Through comparing the selection can completely aspect assurance parts processing quality and meet the technical requirements processing route. Then select machines and tools , calculate and check the cutting dosages ,basic man-hour. Finally, this paper puts forward on the procedure,and fixture desigh task for fixture desigh,complete assembly layout and the drawings,process card,etc process documents.
