Description

Technical Field

[0001] The utility model relates to the technical field of parallel sealing and welding machines, and in particular to a pressing device for parallel sealing and welding machines. Background Art

[0002] During the laser welding process, it is crucial to ensure the stable and accurate docking of the steel frame and the steel plate, which directly determines the quality and firmness of the welding. This is where the clamping assembly plays a role. It can ensure that during the welding process, the steel plate always fits tightly to the steel frame to prevent welding defects caused by position displacement.

[0003] During the laser welding process, when multiple edges of steel frames and steel plates need to be welded, secondary or multiple clamping operations are usually required. The steel frames and steel plates are prone to positional displacement during the clamping process, which directly affects the accuracy of welding. The laser welding head needs to operate according to the preset welding path. If the position of the steel frame and steel plate is offset, the welding head may not be able to accurately weld the butt weld, resulting in incomplete, uneven or leaky welds, which will not only reduce the strength of the welded joint, but may also affect the stability and safety of the entire structure.
