高速立式加工中心主轴箱结构设计及分析

Structure Analysis and Optimization of High Speed Vertical Processing Center Spindle Box

以高速立式加工中心主轴箱为研究对象,为满足高速加工中心整体性能的需要,利用Pro/E软件,建立了4种主轴箱结构的三维模型,分别进行了主轴箱的力学分析和静、热刚度计算,并对4种方案中最优的设计方案进行了合理的结构优化。分析结果表明,箱体内筋板是影响主轴箱整体刚度的重要因素,并通过优化设计改进了筋板结构布局,提高了箱体刚度。

In order to satisfy the performance of machining center, it builds 3D model for the spindle box of DVG850 vertical machining center on the platform Pro/E, simulates the mechanical functions and stiffness characteristic of static and heat, optimizates a reasonable structural design. Analysis results show that the box plate is a important factor on the spindle box stiddness, and structure improvement of stiffened plate and layout of the box can optimizate the box stiffness.
