【摘要】：链式刀库及机械手是高档加工中心的重要功能部件,其性能的优劣程度直接影响着加工中心的整体性能水平。以青海省科技厅计划项目“高档加工中心自动换刀装置性能试验平台研究(2015-GX-205)”为依托,展开对链式刀库及机械手的性能检测技术研究。课题研究目的在于缩短链式刀库产品研发周期,提高其性能检测水平,进而提升其自主研发能力。针对BT50-32T链式刀库及机械手发生掉刀、卡刀、振动过大、电机温升等故障情况,对其故障类型进行总结分析。确定其性能检测项目及相应的检测方法和检测规范,并设计链式刀库及机械手性能测试系统。此系统包括机械结构、控制系统和检测系统,能对链式刀库及机械手的定位精度、振动、噪音、电机温度、气缸压力值和换刀时间进行智能检测、分析、记录。通过现场实验,采集到了检测项目的各项数据,采用科学的方法剔除无用的数据,获取有效的试验数据。通过数据的处理,得到了链式刀库及机械手定位精度的分布规律、振动特性、噪音的分布情况、电机温度的变化规律、气/液缸压力值和换刀时间的变化情况以及其他部件的性能状况。然后利用合理的数学分析方法分析数据,最后根据分析得到的结果来评价被测链式刀库及机械手性能的好坏程度。本文设计的综合性能检测系统和检测方法对链式刀库及机械手在研发和使用中的性能检测方面提供理论依据,具有重要的工程实践意义。
[Abstract]:Chain tool storehouse and manipulator are important functional components of high grade machining center, and their performance directly affects the whole performance level of machining center. Based on the research on the performance test platform of automatic tool changer in high-grade machining center (2015-GX-205), the performance testing technology of chain knife storehouse and manipulator was studied based on the project of Qinghai Science and Technology Bureau. The purpose of this research is to shorten the research and development cycle of chain knife storehouse, improve its performance detection level, and then improve its independent R & D capability. The fault types of BT50-32T chain knife storehouse and manipulator are summarized and analyzed in this paper, such as dropping knife, clamping knife, excessive vibration, temperature rise of motor and so on. The performance test items, the corresponding testing methods and specifications are determined, and the chain tool library and manipulator performance test system are designed. The system includes mechanical structure, control system and testing system. It can intelligently detect, analyze and record the positioning accuracy, vibration, noise, motor temperature, cylinder pressure value and tool changing time of chain cutter and manipulator. Through the field experiments, the data of the test items are collected, and the useless data are eliminated by scientific method, and the effective experimental data are obtained. Through the data processing, the distribution law of positioning accuracy, vibration characteristic, noise distribution and motor temperature change of chain knife storehouse and manipulator are obtained. Change of gas / liquid cylinder pressure and tool changing time and performance of other components. Then the data are analyzed by a reasonable mathematical analysis method. Finally, the performance of the chain knife storehouse and manipulator is evaluated according to the results of the analysis. The comprehensive performance testing system and testing method designed in this paper provide the theoretical basis for the research and development and use of chain tool library and manipulator, and have important engineering practical significance.
