摘要本铣边机主要用于加工特大型船用钢板的焊接,要求能加工各种类型坡口、斜边,并能一次铣削成型,快速高效的加工,同时设计了自动清除铁屑的装置,满足绿色生产的要求。而本文主要对铣边机的总体及压紧机构进行论述,参照了德国数控双面铣边机的相关结构,分析了工作原理和特点,确定了主要工作参数,对机床的整体布局、床身、立柱、横梁、工作台等进行了设计,利用SolidWorks建出三维模型,并利用ansys软件对关键零件进行了有限元分析。43660 由于船用钢板比较大,用一般的机床压紧机构不能很好的满足其加工要求,最终确定选用由液压缸吊起压板进行压紧;对横梁采用焊接加强板的工字梁结构,保证其刚度和稳定性;对钢板的输送还设计了液压滚筒装置,确保加工完成的钢板顺利输送。此外在设计中还充分考虑了加工的方便性和美观性。 毕业论文关键字:铣边机;绿色生产;横梁;压紧装置 Abstract The edge milling machine which is required to fastly and efficiently process various types of groove, edge, and can milling molding at the first time is mainly used for large ship steel plate welding processing, At the same time,to meet the requirement of green production, the machine is designd to equipped with the automatic removal of iron device.With reference to the structure of German CNC double milling machine ,this paper is mainly discussed on overall architecture and compaction mechanism of the milling machine, while it analysises of the working principle and characteristics, determines the main working parameters and designs of machine tool, the overall layout, bed, table, column, beam by using SolidWorks and ANSYS software to build a3D model, finite element analysis key parts. As a result of ship plate is relatively large, the general machine tool clamping mechanism can not satisfy the processing request,finally hydraulic cylinder is choosed to lift and press the plate;To ensure the rigidity and stability of i beam girder welding reinforcing plates are used ;Steel conveyor also has been designed with the hydraulic cylinder device, to guarantee the smooth delivery of finished steel.In addition, the design also takes into full consideration the processing convenience and aesthetics.
