AI Technical Summary

Technical Problem

The existing hole inner wall welding mechanism cannot easily limit the two ends of the welded parts, resulting in the welded parts being easily moved during welding, resulting in the wrong welding position and affecting the welding quality.

Method used

A hole inner wall welding mechanism including a base plate, a third connecting plate, a hydraulic telescopic rod, a slide plate, a welding head, a first support rod, a third support rod, a bracket, a limit frame, a first connecting plate, a second connecting plate, a plug rod and a slot are designed. The welded parts are limited by setting up a bracket and a limit frame, and the movement and welding of the welded joints are achieved using hydraulic telescopic rods and sliders.

Benefits of technology

It effectively avoids the position error of the welded parts during welding, improves the welding quality, and adapts to welded parts of different lengths by adjusting the position of the limit frame.

Abstract

The utility model discloses a hole inner wall welding mechanism, which belongs to the technical field of hole inner wall welding and comprises a bottom plate and a third connecting plate mounted on the bottom plate, a hydraulic telescopic rod is mounted on the third connecting plate, a sliding plate is mounted at the output end of the hydraulic telescopic rod, a welding head is mounted on the sliding plate, and a first supporting rod is mounted on the bottom plate. A third supporting rod is installed on the bottom plate in a sliding mode, brackets are installed on the third supporting rod and the first supporting rod, limiting frames are installed on the brackets, and a first connecting plate is installed on the first supporting rod in a sliding mode. The brackets are arranged on the first supporting rod and the third supporting rod and can support a welding piece, the limiting frames are arranged and can limit the two ends of the welding piece, and the situation that the welding piece slides on the brackets in the welding process, consequently, the welding position is wrong, and the welding quality is affected is avoided.
