Technical Field

[0001] This utility model belongs to the technical field of welding positioners, and in particular relates to a welding positioner flipping working device for welding positioners. Background Technology

[0002] A welding positioner is a device used to move a workpiece to be welded, guiding the weld seam to an ideal position for welding. The core function of a welding positioner is to optimize the welding position and improve efficiency and quality through the rotation, tilting, and lifting of the workpiece. It works in conjunction with welding robots and manipulators to form automated welding equipment. Existing welding positioners are structurally limited; their rotary tables can only achieve unidirectional rotation, not simultaneous forward, backward, left, and right tilting angles. This results in functional deficiencies, low welding efficiency, and inconvenience. Therefore, the design of a welding positioner suitable for large steel structures is crucial for improving welding efficiency, ensuring welding quality, adapting to automation trends, and meeting diverse welding needs.

The driven bearing housing is mounted on the second fixed platform. The connecting cylinder of the driven-end clamping connecting plate passes through and extends out of the driven bearing housing. The connecting cylinder is rotatably connected to the driven bearing housing via a bearing. A roller device is provided at the bottom of the second fixed platform, and the roller device slides in cooperation with the slide rail provided below the second fixed platform.

[0005] Furthermore, the aforementioned power output assembly also includes a sprocket limiting device. The sprocket limiting device is mounted on the first fixed platform and located behind the output sprocket. The sprocket limiting device has several limiting holes, and the outer end face of the output sprocket has several positioning holes along the circumferential direction. The sprocket limiting device and the output sprocket are fastened together by several pins installed in the corresponding limiting holes and positioning holes.

[0006] Furthermore, the aforementioned roller device includes a roller, a roller shaft, and a roller bearing housing. The roller bearing housing is fixedly mounted on the second fixed platform, and the roller is rotatably mounted on the roller bearing housing via the roller shaft.
