摘　　要：连杆裂断加工工艺已开始逐步取代传统的连杆分体加工工艺。应力槽加工是连杆裂断加工的重要工序之一。针对拉削加工刀具损耗快、激光加工设备贵的问题,发明了一种双工位倒立式裂断连杆应力槽电火花线切割机床,设计了机械结构,研制了脉冲电源,开发了控制系统,并通过实验证明其具有高效、低成本的优势。The cracking technology of connecting rod has gradually replaced the traditional manufacturing technology of connecting rod,and the processing of stress groove is one of the most important processes in the new process.Aiming at the problem of fast cutting tool wear and high cost of laser processing equipment,a double-station inverted-fracture connecting rod stress groove cutting machine tool was developed,a new type of double-station inverted cracking rod electric spark cutting machine tool has been developed.
