液力变矩器机器人FCAW技术

Robot FCAW Technique Hytrodynamic Torque Converter

根据液力变矩器上盖连接块焊接接头形式、动平衡使用特点、焊缝金属高性能指标、焊接质量零缺陷控制要求，采用机器人＋变位器柔性焊接系统，解决了焊缝几何尺寸一致性、空间位置对称性、填充金属均匀性的技术关键。并阐述了机器人系统的焊接电源、变位器和送丝机构的合理配置，通过工艺试验确定了液力变矩器上盖连接块ＦＣＡＷ工艺参数以及防止焊接缺陷的工艺措施。

According to the weld connector shape of top cover joint block of hytrodynamic torque converter, dynamic balance characteristic in use, higher seam metal performance index and zero defect for welding quality. To meet the requrirements, the robot + position - changeable flexible welding system is used to solve the key technical problems of geometric dimension consistency, symmetry in space position and metal filling homogeneity. The rational arrangement among the welding power of the robot system, position changer and wire feeder is described. The FCAW technological parameters of the top cover joint block of the hytrodynamic torque converter and the technological measures of preventing the welding defect are determined through the technological test.
