平移浮动式仿行刀具的设计 摘要 根据实际应用的需要，钢管应进行平端面加工，用于焊接的钢管还应进行倒焊接坡口的加工。倒棱机是钢管端面加工的专用设备。目前传统倒棱机的加工质量仍无法满足市场要求，而进口倒棱机价格昂贵，且服务周期长，因此，研发加工质量和生产能力均满足实际要求的新型国产倒棱机迫在眉睫。 本文研究了钢管倒棱的工作原理，完成了倒棱机的总体方案设计；对其机械结构特别是影响加工精度的重要部件，即刀具和浮动刀盘装置进行研究并做了详细的设计。论文的具体内容安排如下： 第一章主要通过介绍钢管端面倒棱加工的意义和工艺过程，阐述了开发钢管自动倒棱机的必要性，介绍了钢管自动倒棱机技术的研究现状和发展方向，提出了本文的主要研究内容。 第二章根据倒棱机设计要求和参数，提出了倒棱机刀盘的总体布置方案，确定了各主要部件的功能和结构。 第三章计算了切削力，设计了浮动刀盘,选择和校核关键部件。 第四章对无缝钢管倒棱机刀盘的研制工作进行了总结。 关键词： 钢管 倒棱 仿形 刀具 Design of the translation floating tracer tooling ABSTRACT According to the actual application, the steel pipe-end should be flattened or cut the welded groove with the pipe used in welding. Chamfering machine is the special equipment for pipe-end processing. Currently, the processing quality of the traditional chamfering machine is still unable to satisfy the demands of the market，while exotic chamfering machine is expensive, long cycle of services．therefore，the research and development of new domestic chamfering machine meeting all actual requirements in the quality and capacity of the processing is imminent． This paper established the overall design program of the fully automatic chamfering machine on the basis of researching the working principle of steel pipe chamfering．Its mechanical structures，especially important components impacting the precision machining, namely tool and floating cutter devices has been researched and done a reasonable design .The specific content of the thesis is as follows: The first chapter introduced the significance of the pipe end—chamfering and its process，elaborated the necessity of developing expounded NC chamfering machine，introduced the status and development direction of the technology and raised the papers major content． The second chapter raised the cutter of Chamfering machine on the design requirements and parameters．identified the function and structure of the major components. The second chapter raised the overall layout program based on the design requirements and parameters, an
