专用点焊机工作台的设计与研制

The design and development of specific spot-welding bench

为了提高点焊机加工零件的质量和效率,实现工作台转盘旋转定角度时点焊工艺,提出了专用点焊机工作台设计及基于PLC控制系统设计的总体方案,阐述了关键指令DZRN和DDR-VA的应用。生产实践表明,螺母焊接位置纵向、横向运行偏差在±0.03 mm以内,同时具有效率高、运行可靠的特点。

In order to improve the quality and efficiency in processing the parts by welding machine and accomplish welding process in preset turntable rotation angle,an overall project is put out which involved the design of special spot-welding bench and control system based on PLC,and describes the application of key commands DZRN and DDRVA as well.Production practice shows that the deviation of nut position in vertical welding is ±0.03 mm or less,and the system has the characteristics of high efficiency and high reliability.
