摘　　要：轮毂作为车辆的一个重要部件,对车辆行驶平稳性、安全性、操作性都有重要的影响。针对目前国内小型轮毂生产企业采用传统的手工焊接方式,存在的工人劳动强度大、焊接质量不高、生产效率低等问题,利用现有的焊接设备,提出了一种新型的全自动焊接系统方案。以PLC为控制系统,该控制系统软件部分包括I/O人机互动程序的开发和焊接主控程序的编制,实现了手动控制和自动控制两种模式的转换运行;在环形焊缝焊接过程中采用焊缝自动跟踪系统,并采用高品质的MAG焊,实现了焊接角度与速度的自动调节,提高了整机的自动化程度和焊接质量。研究结果表明,通过采用该自动焊接系统能够满足车辆行驶时对轮毂焊缝的要求,而且能大大提高焊接质量和生产效率,降低制造成本和工人劳动强度。As an important component, wheel hub is very important for vehicle driving stability, safety and operation. Aiming at the low quality and low production efficiency of small domestic wheels manufacturers using the traditional manual welding way, a new type of automatic welding system was put forward using exiting welding equipment. The PLC was utilized as the control system which the development of human-computer interaction program and welding master program was included. In the girth weld welding process, automatic seam tracking system was used and MAG welding of high-quality was adopted, which can easily adjust the welding angle and speed and improve the reliability. The results indicate that the welding system improves the welding quality and production efficiency greatly and reduces costs and labor intensity.
