Description

Technical Field

[0001] This utility model relates to the field of welding positioning technology, and in particular to a quick positioning device for equipment door panels. Background Technology

[0002] Welding is a common method in machining to connect several independent workpieces. However, without a proper positioning fixture, the welding quality is extremely unstable, the workpieces are difficult to position, and they are prone to falling off.

[0003] During the processing of equipment door panels, multiple different sheet metal workpieces need to be welded to both ends and the interior of the door panel frame. Traditional processing methods often rely on laser marking and positioning on the workpieces and door panel frames, followed by manual alignment. This method is not only costly in terms of processes and equipment, but also fails to meet the requirements for hole concentricity, parallelism, and dimensional accuracy. After welding, reshaping and rework are often required, resulting in low efficiency and high costs.

[0004] Therefore, there is an urgent need for a rapid positioning device that is simple in structure, easy to change, and reliable in positioning. Utility Model Content
