【摘要】：近年来,随着航空、航天、汽车、船舶、仪表等行业的快速发展,齿轮产品的数量和种类均大幅度增加,齿轮制造加工企业的滚刀及夹具的种类和数量也不断增多,而目前国内外对刀具管理研究过程中,针对滚刀及夹具的信息化管理的研究相对薄弱。为此,本文以滚齿机刀具、夹具管理系统为研究对象,解决对其进行信息化管理过程中涉及到的识别问题。首先,分析了滚齿机刀具、夹具识别的特点及需求,由此提出一种基于二维条码识别技术、RFID技术的滚齿机刀具、夹具识别方案。本文通过重点阐述了针对刀具、夹具与加工任务的匹配识别过程,描述了滚齿机刀具、夹具的在位及在机识别,特别是在机识别,为滚齿机刀具、夹具的在线实时监测奠定了基础。其次,对滚齿机刀具、夹具自动化识别实现过程中的关键技术进行了研究。其中,关键技术主要包括:基于二维条码及RFID的滚齿机刀具、夹具识别技术;滚齿机刀具、夹具识别的硬件装置设计及在滚齿机上的安装技术;基于西门子S7-300PLC的自动化控制技术,即RFID读写头对RFID芯片的读写操作、轴的转动控制及伺服传动系统的控制;刀具、夹具信息的自动上传,包括智能终端提取PLC里面的信息及通过RS232通讯协议上传刀具及夹具信息。最后,基于上述滚齿机刀具及夹具与加工任务的匹配过程及相应关键技术的研究,并在重庆机床集团的YS3118CNC5及YS3120CNC6滚齿机上对系统进行了验证,取得了较好的效果。
[Abstract]:In recent years, with the rapid development of aviation, aerospace, automobile, ship, instrumentation and other industries, the number and types of gear products have increased substantially, and the types and quantities of hobs and fixtures in gear manufacturing and processing enterprises have also been increasing. However, in the research process of tool management at home and abroad, the research on information management of hob and fixture is relatively weak. Therefore, this paper takes the tool and fixture management system of gear hobbing machine as the research object, and solves the problem of identification in the process of information management. Firstly, the characteristics and requirements of gear hobbing machine tool and fixture identification are analyzed, and a recognition scheme of gear hobbing machine tool and fixture based on two-dimensional bar code identification technology and RFID technology is put forward. In this paper, the matching recognition process of cutter, fixture and machining task is expounded, and the recognition of hobbing machine tool, fixture and in machine, especially in machine recognition, is described. On-line real-time monitoring of jigs has laid the foundation. Secondly, the key technology of automatic recognition of gear hobbing machine tool and fixture is studied. Among them, the key technologies include: gear hobbing machine tool, fixture identification technology based on two-dimensional bar code and RFID, the hardware device design of gear hobbing machine tool and fixture identification, and the installation technology of gear hobbing machine. The automatic control technology based on Siemens S7-300 PLC, that is, the reading and writing operation of RFID reader head to RFID chip, the rotation control of shaft and the control of servo drive system, the automatic uploading of tool and fixture information, Including intelligent terminal to extract information from PLC and upload tool and fixture information through RS232 communication protocol. Finally, based on the research of matching process and key technology between the cutting tool and fixture of the gear hobbing machine, the system is verified on YS3118CNC5 and YS3120CNC6 hobbing machine of Chongqing Machine tool Group, and good results are obtained.
