Description

Technical Field

[0001] The invention relates to the technical field of ship deck assembly welding, and in particular to automated assembly and welding equipment for ship deck assemblies. Background Art

[0002] The ship deck is one of the most important components of a ship. It not only provides a safe working and activity platform for crew members and passengers, but also carries cargo, equipment and other important facilities. The ship deck can be divided into several different parts, depending on the type and design of the ship. The general ship deck components include: main deck, superstructure, hatches, cranes, lifeboats and life rafts, railings, ventilators, hatch covers, anchors and anchor chains, masts and rigging, etc. The mast is an important structural component on the ship.

[0003] The main function of the mast is to support sails, antennas, signal lights, navigation lights, sail drive systems and other equipment. In modern ships, the functions of the mast are more diversified. It is not only limited to sailboats, but also includes the installation of various communication and navigation equipment. Since ships operate on the water all year round, the entire ship has a large swaying motion and is often affected by wind on the water. It is difficult to ensure the supporting strength of the bottom of the mast using a single pole for support, so multiple ribs are welded on the base of the mast to strengthen the structural strength.

[0004] The existing welding method of the rib plate on the mast base is mostly carried out in steps. It is necessary to first position the rib plate by spot welding, and then manually weld the overall connecting seam. This method requires spot welding while supporting the rib plate, which is difficult for one person to operate. It is easy for the rib plate to be supported in an oblique manner, resulting in inaccurate positioning, affecting the welding verticality of the rib plate, and unable to ensure the structural strength increase effect of the rib plate. In addition, multiple sets of rib plates are generally welded on the same mast base. In order to consider uniform strength distribution, multiple sets of rib plates are generally distributed equidistantly around the circumference. Manual equal-distance distribution is time-consuming and cannot ensure equal-distance distribution. The work quality and efficiency need to be improved. Summary of the invention

After pressing tightly, move your hands away.

[0052] S3: Then, the laser welding gun head 31 is controlled to move vertically by telescoping the electric push rod 2 323 to weld the vertical seam of the connecting seam. When the abutment 36 and the contact sensor 35 are in contact, the contact sensor 35 senses a contact signal, which indicates that the laser welding gun head 31 has reached the horizontal connecting seam position between the rib plate and the mast base.
