摘　　要：目前国内的拉床多采用液压驱动,针对其存在加工质量(精度和光洁度)不佳、能源浪费和环境污染等的问题,在技术成熟和性能优越的永磁交流伺服系统的基础上,设计了一款基于永磁交流伺服系统同步驱动的拉床系统。首先给出了电伺服同步驱动的立式内拉床的机构图,并对该机构图的性能特点进行了分析。重点阐述了主溜板伺服同步驱动系统、调刀伺服驱动系统和拉床控制系统软件设计方案,并采用共享指令的同步控制策略来确保拉床同步性能。最后,以立式内拉床为对象,在20 t的负载力下进行了试验测试。测试结果表明,设计的基于永磁交流伺服同步驱动的拉床控制系统具有成本低、可行性好、同步性能测试稳定、加工精度高等优点,对国内拉床的发展具有一定的指导意义。Most domestic broaching machine with hydraulic drive,aiming at the drawbacks that domestic broaching machine are processing quality( accuracy and finish) poor,energy waste and environmental pollution,a system of broaching machine based on permanent magnet AC servo system synchronous driving with the sophisticated intelligent and superior performance permanent magnet AC servo system was designed. The advantage of servo synchronous driving broaching applying in industrial production was described firstly,the vertical internal broaching of servo synchronous driving charts was also given,and an analysis of the characters of organization chart was provided. The design of main slider servo synchronous driving systems,tool servo drive systems and control system software of broaching are expounded emphatically,and the synchronization control strategy of sharing instruction was used to ensure the synchronization performance of broaching machine. Finally,the vertical internal broaching machine was tested under a load of 20 tons force. The test results indicate that the designed control system has the advantages of low cost,good feasibility,stable synchronization performance,high manufacturing accuracy,which has a certain guiding significance for development of domestic broaching machine.
