Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ship plate welding, and particularly relates to a convenient straightening positioning mechanism based on a ship plate welding scene. BACKGROUND

[0002] A ship structure is first formed by welding a bottom plate, a face plate and a web frame to form a plate frame structure, and then formed by welding various corresponding plate frame structures to form the entire ship body. Due to the ship structure, the welding between the steel plate and the frame is generally a long-distance welding of 50-100 meters, and the plate is mostly thin, and the structural strength of a single segmented face plate or web plate is weak, which leads to great difficulties in cutting, straightening, assembling and welding, placing, transporting, turning and hoisting during the plate manufacturing process, and the plate frame structure is easily deformed.

[0003] For the straightening of the plate deformation, there are currently two processes, one is to strictly require the plate precision and quality during cutting and blanking before the assembling and welding process, and to well support the plate during transportation to reduce the plate deformation. The deformed plate needs to be straightened offline through a complex tool before assembling and welding. This method needs to increase the process, which seriously increases the plate manufacturing cycle. The second is to straighten the deformed plate after assembling. This method is relatively complex, and is generally a special tool, which is inconvenient to operate. A special straightening tool is needed to be installed on the corresponding position of the bottom plate, face plate and web plate to straighten the plate, which is complicated and increases the manufacturing complexity of the ship structure.
