摘　　要：针对铝合金机器人本体钢丝螺套被带出失效的故障,开展了基材强度检测、焊接热影响区试验、钢丝螺套安装底孔直径试验等研究,明确了钢丝螺套失效原因。创新性提出了在安装钢丝螺套的同时涂螺纹胶的方法,有效避免了因钢丝螺套安装底孔加工精度不足导致失效的现象。Aiming at the failure of the wire thread insert of the aluminum alloy robot body,this paper carried out research on the strength of the substrate,welding heat affected zone test,and the diameter test of the bottom hole of the wire thread insert installation,and identified the failure cause of the wire thread insert.The method of applying thread sealant at the same time when installing the wire thread insert is innovatively proposed,which effectively avoids the phenomenon of failure caused by the insufficient machining precision of the bottom hole of the wire thread insert installation.
