【摘要】 在批量生产中,常会使用工装夹具来提高精度和效率。夹具的质量决定了加工质量,若其刚性差会直接降低加工精度。本文用有限元的方法分析夹具最大变形区位置,在最大变形区附近设计增强结构来减小变形提高结构刚性。实践结果证明该方法可有效提高结构刚性,对其他产品的设计也有借鉴作用。更多还原

【Abstract】 In mass production, jig is often used to improve accuracy and efficiency. The quality of the jig directly determines the machining accuracy, and the rigidity difference will directly reduce the machining accuracy. In this paper, the position of the largest deformation zone of the jig is analyzed by finite element method, and the augmented structure is designed to be close to the maximum deformation zone to reduce deformation and improve rigidity of the structure. Practice has proved that this method effectively improves structural rigidity, and can be used for reference in other products design.更多还原
