| 摘 要： | 针对现有气动随焊锤击装置附加设备多、控制精度等特点，设计了一套适时进行随焊锤击的自动化控制系统。系统采用AT89C52单片机为控制核心，MAX191为A/D转换器，FA2B型红外测温仪跟踪采集焊道温度与85BYG-450B型步进电机作为动作执行部件，构成了由温度信号采集单元、锤击力和锤击频率控制单元和步进电机控制单元组成的控制电路。低碳钢磨损试件进行随焊锤击修复试验表明：控制系统结构紧凑、电路工作可靠，锤击参数控制准确，试件焊接气孔、裂缝等缺陷得到明显改善。

| Abstract: | Equipment of welding with trailing peening uses gas as motivity at present. Its disadvantage is excessive extra equipment, lower control precision. In order to improve its disadvantage and increase production efficiency, the automated control system of welding with trailing peening using MCU(Micro Control Unit) AT89C52, the infrared thermoscope FA2B, the A/D converter MAX191, the stepping motor 85BYG-450B was designed. The AT89C52 single-chip is control system core. The temperature parameter was gathered by infrared thermoscope which tracked the weld, MAX191 transforms the signal from analog to digital, 85BYG-450B stepping motor and 2H090MH stepping motor driver were used as driving device. The main control circuit was made up of temperature acquisition unit, peening parameter control unit and stepper motor control unit. Through the repair experiment on the low-carbon steel attrition specimen, the experimental results show that the control system has a small volume, the circuit is reliable, welding defect is clearly improved for example blowhole, crack and so on. |
