【摘要】 随着现代科学技术的不断发展,各行业对机械产品的性能要求都有了很大的提高。无氧铜以其优异的物理机械性能以及良好的抗腐蚀抗磁性能在石油、航空航天等行业得到了广泛的应用。无氧铜材料腔体结构的零件常作为石油、航空航天行业的主要精密零件,对无氧铜腔体结构进行珩磨研究,为提高机械制造水平,发展我国的石油、航空航天的事业具有重要作用。本研究以无氧铜的腔体作为研究对象,针对无氧铜腔体深孔珩磨加工进行了系统研究。通过分析无氧铜材料的磨削性能及其影响因素,并根据该腔体的特殊结构,再结合工厂加工经验设计并制造出一套适合无氧铜腔体结构的新型珩磨头。采用该新型珩磨头在不同磨削用量下对无氧铜腔体进行珩磨加工试验,通过理论分析和试验研究得到新型珩磨头的合理磨削用量和最佳珩磨油石的粒度,并对珩磨加工中所遇到的问题进行分析,提出了问题的解决措施。试验结果证明,利用本课题设计的新型珩磨头对无氧铜腔体进行珩磨加工,加工过程平稳,加工效果良好。更多还原

【Abstract】 With the constant development of the modern science technology, the performance requirements of mechanical products for various sectors have been greatly improved. Oxygen-free copper with its excellent physical& mechanical properties, good corrosion-resistant and anti-magnetic properties have been widely used in the Oil, Aeronautics & Astronautics and other industries. The parts of Cavity Structure which is Oxygen-free copper often as mainly precision parts in oil, aerospace industry, a study of the honing machining of Cavity Structure on the oxygen-free copper was carried out, so machine level well can be improved and it will play an important role in the development of China’s oil, aviation.Cavity of Oxygen-free copper was taken as object of study, and systemic study have been done for the Deep-hole Honing for Cavity of Oxygen-free Copper. According to its materials’ grindability, its influencing factors,the Special Structure of Cavity and combining with the experience of factory, we have designed and manufacture a set of special honing head, which can be suitable for processing the Cavity Structure of Oxygen-free copper. The experiment of honing under different grinding parameters has been done for the new honing head. Through the theoretical analysis and experimental research, reasonable grinding parameters and optimal abrasive is identified for the honing head. The solutions of the problems are propounded by analyzing the honing and the problems which encountered by the processing. The testing results show that the machining-process is smooth and the effect of machining is good while we honing the Cavity of Oxygen-free copper by the designed a set of special honing head.更多还原
