一种管道外根焊装置
摘要：
本发明属于管道焊接技术领域，公开了一种管道外根焊装置，包括：固定夹持组件、移动夹持组件、导杆、平移液压缸、焊接机器人以及机器人导轨；导杆设置在固定夹持组件和移动夹持组件之间；平移液压缸分别与固定夹持组件和移动夹持组件相连；固定和移动夹持组件分别包括：上框架和下摆臂；下摆臂通过铰轴与上框架铰接；机器人导轨固定在固定夹持组件上，焊接机器人置于导轨上；其中，在进行对口操作时，管道抵靠在上框架内侧，下摆臂将管道压紧在上框架内；平移油缸拉动移动加持组件向固定夹持组件移动。本发明提供了一种结构简单，焊接高效，对正可靠的根焊装置。
摘要（英）：

The invention belongs to the technical field of pipeline welding and discloses a pipeline outer root welding device. The pipeline outer root welding device comprises a fixed clamping assembly, a movable clamping assembly, guide rods, a translation hydraulic cylinder, a welding robot and a robot guide rail. The guide rods are arranged between the fixed clamping assembly and the movable clamping assembly. The translation hydraulic cylinder is connected with the fixed clamping assembly and the movable clamping assembly. The fixed clamping assembly and the movable clamping assembly comprise upper frames and lower swing arms, and the lower swing arms are hinged to the upper frames through hinge shafts. The robot guide rail is fixed to the fixed clamping assembly, and the welding robot is arranged on the guide rail. When opening alignment operation is carried out, pipelines butt against the inner sides of the upper frames and pressed in the upper frames through the lower swing arms; the translation hydraulic cylinder pulls the movable clamping assembly to move towards the fixed clamping assembly. The root welding device is simple in structure, efficient in welding and reliable in alignment.
