Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sheet metal welding technology, specifically relating to a sheet metal positioning and welding fixing device. Background Technology
[0002] In the welding process of sheet metal parts, accurate positioning and reliable fixing are key factors in ensuring welding quality. Currently, common methods for positioning and fixing sheet metal parts for welding have many problems. For example, some traditional fixing devices can only clamp sheet metal parts from a single direction, failing to provide comprehensive and stable fixation. During welding, the sheet metal parts are prone to deformation due to uneven stress, further affecting welding quality. Furthermore, using simple clamps to hold sheet metal parts is difficult to adapt to sheet metal parts of different sizes, has low positioning accuracy, and is prone to displacement during welding, resulting in uneven weld joints, large dimensional deviations, and affecting product quality and subsequent performance.
[0003] Therefore, further improvements will be made to address the aforementioned issues. Utility Model Content
