摘要
基于增材制造技术和减材制造技术的优势,以及微小零件的加工制造需求,设计了1台桌面型增减材复合机床。使用三维建模软件进行机床的结构和参数化设计,并进行了机床的虚拟装配,确保了机床实体的可装配性。针对构建的桌面增减材复合机床原型系统,以螺栓连接为对象,通过实验,分析了螺栓拧紧力矩对机床定位误差的影响,找到合理的拧紧力矩值,提高机床的装配精度和可靠性。
Based on the advantages of the additive manufacturing technology and the subtraetive manufacturing technology, a desktop hybrid additive and subtractive machine tool for manufacturing of small parts is designed in this paper. The three-di- mensional modeling software for machine tool is used for the structural and parametric design, and virtual assembly of the ma- chine tool is completed to ensure the assembling ability of the machine tool. Aiming at the prototype system of the desktop hy- brid additive and subtractive machine tool, with bolts as the objective, the influence of bolt tightening torque on position error of machine tool is analyzed through scientific experiments, so as to find the reasonable tightening torque value and improve the assembly accuracy and reliability of the machine tool.
