直角坐标型钢坯标示机构的设计与分析

摘要

By combining printing and arc spraying,a set of machinery for red billet online marking with a high energy beam gun was designed,which can mark more characters on billet in the small specification end. Based on rectangular coordinat-ing mechanism,cantilever structure was adopted to realize the marking. Through the coordination of three ball screws of X、Y and Z rolling in three directions,words,numbers,letters,special characters,etc can be marked on the billet.The model was established and simulated with UG,and the modal analysis was conducted with ANSYS Workbench,based on which,plans to improve the structure was put forward. Compared with the prototype,the feasibility of the improved scheme was much higher. The research can provide a theoretical basis for further optimization of the structure.%基于冲印式和电弧喷涂式的钢坯标示方法，设计了针对红热钢坯在线标示的高能束标示机构，以实现小规格钢坯端面的多字符标示。机构以直角坐标型标示形式为基础，采用悬臂式结构，通过 X、Y、Z 三个方向滚珠丝杠的协同作用，实现包括数字、字母、特殊字符等在内的字符标示。利用ANSYS Workbench软件对UG软件建立的标示机构模型进行模态分析，针对模态分析结果提出结构改进方案，依据实际标示效果确定改进方案的可行性，为进一步优化结构提供理论依据。
