摘　　要：定位连接部件是全自动激光打标机中的重要结构件,主要用于定位机构中定位架和支撑板的连接。使用SolidWorks软件的的有限元分析功能,对定位连接部件进行静应力分析,发现部件中最大应力和位移发生在定位架零件两伸出端与主体结合部。从优化部件尺寸和重量的角度出发,开展以增加定位架强度、减轻连接板自重为目标的结构优化设计,并采用同样的有限元分析方法对优化结果进行验证。结果表明,通过定位架伸出端与主体夹角和连接板槽口尺寸的优化,能够保证部件总体足够强度和刚度的前提下,有效减小定位连接部件的自身重量,降低零件生产成本。The positioning connection component is an important structural component in a fully automatic laser marking machine,mainly used for connecting the positioning frame and support plate in the positioning mechanism.By using of the finite element analysis function of Solidworks software,static stress analysis has been conducted on the positioning connection components,and it is found that the maximum stress and displacement in the components occur at the joint between the two protruding ends of the positioning frame parts and the main body.From the perspective of optimizing component size and weight,structural optimization design has been carried out with the goal of increasing the strength of the positioning frame and reducing the self weight of the connecting plate.The same finite element analysis method has been used to verify the optimization results.The results indicate that by optimizing the angle between the extended end of the positioning frame and the main body,as well as the size of the connecting plate groove,the overall strength and stiffness of the components can be ensured,effectively reducing the weight of the positioning connecting components and reducing the production cost of the parts.
