Description
Technical Field
[0001] This utility model relates to the technical field of welding positioning devices, and in particular to a segmented automatic welding positioning device based on sheet metal processing. Background Technology
[0002] With the rapid development of the automotive, aerospace, electronic equipment, and machinery manufacturing industries, the demand for sheet metal parts is constantly increasing. These industries also have higher and higher requirements for the quality, precision, and production efficiency of sheet metal parts. Sheet metal processing usually includes multiple processes such as cutting, bending, stamping, and welding. Welding, as one of the key processes, directly affects the structural strength and overall quality of sheet metal parts. Different sheet metal products may require different welding processes and methods, such as arc welding, laser welding, and resistance welding.
[0003] Currently, segmented automatic welding positioning devices for sheet metal processing on the market mainly consist of support and load-bearing components and positioning components. The shapes of sheet metal parts are becoming increasingly complex, such as irregular curved surfaces, polyhedral structures, and special concave and convex shapes. Traditional integral fixing methods are difficult to fully fit these complex shapes, causing sheet metal parts to easily shift during welding, affecting welding accuracy. Different sheet metal materials have different elastic moduli and coefficients of thermal expansion, and are prone to deformation when heated during welding. Some thin sheet metal parts deform more significantly. Even if they are fixed before welding, the thermal stress during welding may still cause them to change shape, thus rendering the original fixing method ineffective. Traditional fixing methods often cannot achieve high-precision positioning. For example, using simple clamps or manual positioning cannot guarantee the positional accuracy of welds for some sheet metal parts with high welding accuracy requirements, and problems such as weld offset and uneven width are prone to occur.
