Beschreibung
Zusammenfassung:	The invention discloses a positioning mechanism. A rotating plate, a first rod, a second rod and a third rod form a framework structure, a drive device can drive the rotating plate to swing in a reciprocating mode, the third rod can go in or out of a part of a box-type structure and to be welded, the rotating plate, the first rod and the second rod form an avoiding space, the avoiding space can bypass a surrounding structure, a supporting block on the third rod can be used for positioning and supporting the surrounded part, and thus welding of the part of the box type structure can be achieved. By means of the positioning mechanism, the defect that the part of the box type structure is not prone to being positioned in the welding process is overcome, fast and precise positioning of the part of the box type structure can be achieved, and welding efficiency is improved greatly.
