Description

Technical Field

[0001] This utility model relates to the field of elevator manufacturing technology, and specifically discloses an elevator car sheet metal welding equipment with multi-angle auxiliary support. Background Technology

[0002] In the welding manufacturing process of sheet metal parts for elevator cars, it is usually necessary to position and clamp sheet metal parts of different shapes and sizes to carry out welding operations; existing welding support or clamping equipment mainly has the following technical defects:

[0003] Existing equipment often uses simple fixed supports or adjustment mechanisms with only a single degree of freedom, making it difficult to flexibly and accurately position sheet metal parts at multiple angles in three-dimensional space. This results in poor accessibility for welding operations, making it difficult to adjust the weld to the optimal welding position, which seriously affects welding quality and efficiency. This problem is particularly prominent for complex car sheet metal parts.

[0004] Existing fixtures are mostly rigid structures, lacking effective buffering and self-adaptive mechanisms. When clamping irregular curved surfaces or thin-walled sheet metal parts, they are prone to local stress concentration and deformation. At the same time, under the action of welding thermal cycle, the thermal expansion and contraction of sheet metal parts cannot be effectively absorbed, which in turn causes the sheet metal parts to move or the welding stress to deform, directly affecting the dimensional accuracy and structural strength of the product.
