摘要
针对工程机械回转类零件堆焊修复工艺,研制了一种新型变位机。通过堆焊变位机结构及传动的设计,实现了对工件的夹持、翻转、回转,以适应堆焊中对工件空间位置及运动的要求。基于变频调速技术,实现了堆焊变位机工作台主轴的无级变速、启动、停止及正/反转控制;应用电气控制技术,实现了变位机运转的独立控制模式、联机控制模式的切换与互锁。该堆焊变位机已在天津工程机械研究院的"工程机械零部件再制造关键技术与装备"这一科研项目中得到了成功应用。结果表明,堆焊变位机能实现有效提高工程机械回转类零件堆焊修复的灵活性及自动化程度。
Aiming at surfacing process for construction machinery disk type part, a new positioner was developed. The workpiece clamping, tilting and rotating were realized through the structure and transmission designing of the positioner. On the basis of frequency control, some functions such as infinitely variable speeds control, start, stop, status display and protection for positioner spindle were realized automatically. Applying electric control technique, two kinds of control modes were realized. The independent control mode and online control mode can be switched and interlocked. This positioner has been applied successfully in the project of ＂key technology and equipment for construction machinery parts remanufacturing＂ in Tianjin research institute of construction machinery. The results indicate that the application of this positioner may increase the automaticity and productivity effect remarkably.
