在工程机械加工制造过程中,铸造壳体类零件常因形状不规则、结构复杂、加工面积较大等原因,存在加工难度高、平面度等表面质量难以保证,合格率不稳定等问题.为了有效提升加工效率,降低生产成本,本文基于实际的加工条件和环境,以壳体平面铣削加工为研究对象,采用有限元分析方法,对铣削力进行了计算,进而对壳体变形量进行了分析.针对最大变形位置,结合已成熟的装夹方法,在工件薄壁处采用反向预紧支撑方式,有效改善了大批量生产加工中壳体加工平面度质量问题.
Quality Improvement of Shell Plane Milling Based on Finite Element Analysis
In manufacturing of casting shell parts,there are some problems such as difficulty in processing and ensu-ring surface quality such as flatness,and unstable qualification rates,due to irregular shapes,complex structures,and large machining areas. In order to effectively improve processing efficiency and reduce production costs,base on the actual pro-cessing conditions and environment,this article takes the shell surface milling as the research object. The finite element a-nalysis method is used to calculate the milling force and then the deformation of the shell is analyzed. For the maximum de-formation position,by adopting mature clamping methods and using the reverse preload support mode at the thin-walled part of the workpiece,the problem of the machining flatness quality of the shell in mass production is effectively improved.
