Description

Technical Field

[0001] The utility model relates to the technical field of tee pipe welding, and more specifically to a welding tool for a branch pipe and a main pipe of a tee pipe. Background Art

[0002] A pipe joint with three openings is called a tee. It is widely used in pipe networks for transporting liquids and gases. Due to different transport media, the materials of tees are divided into: cast iron, cast steel, cast copper, cast aluminum, plastic, glass, etc.

[0003] At present, the common processing method of metal tee pipes is to use a welding tool to weld a branch pipe on a main pipe. The working process can be roughly divided into three steps: first, the main pipe and the branch pipe are simply welded together to play a temporary fixation role, then the main pipe is placed in the welding tool, and a clamping head is pushed by the cylinder equipped on the welding tool to clamp the branch pipe, and finally a laser welding robot is used for welding. In the process of clamping the main pipe and the branch pipe, the branch pipe needs to be kept vertical. However, most of the existing welding tools rely on the staff to visually observe and manually adjust the position of the branch pipe, which makes it difficult to ensure the verticality of the branch pipe. If the branch pipe is tilted, the clamping head may push it out of the welding tool when it contacts the branch pipe. Therefore, it is urgent to design a welding tool for the branch pipe and the main pipe of the tee pipe to solve the above problems. Utility Model Content
