摘　　要：现有高速线切割机床的上丝装置在上丝过程中易发生断丝与张紧力不均衡现象,降低了机床切削稳定性和工件加工质量。通过分析现有装置的结构,提出增加推力球轴承,以防止锁紧螺母跟转而导致储丝盘卡顿引起断丝;根据丝线的拉力计算出弹簧压缩量及其他相关参数。经I-DEAS软件建模、装配、仿真表明,该装置可以满足生产要求。The existing winding device of high-speed WEDM machine is prone to break and tension imbalance in the process of thread feeding,which reduces the cutting stability of the machine tool and the quality of workpiece processing.By analyzing the structure of the existing device,the thrust ball bearing is added to prevent the locking nut from following and causing the wire storage disc to jam and cause wire breakage;Calculate the spring compression and other related parameters based on the tension of the silk thread.The modeling,assembly and Simulation of I-DEAS software show that the device can fit for the production requirements.
