Description

Technical Field

[0001] The invention relates to the technical field of deck welding, and in particular to a deck welding device with good positioning effect. Background Art

[0002] Deck welding is a very important part of shipbuilding and maintenance, and involves welding work on the ship deck and its accessories. Welding is mainly carried out by submerged arc welding, manual welding and other methods. The deck is the load-bearing structure and operating area on the ship, and the welding quality directly affects the structural safety and service life of the ship. During the welding process, the welding parameters must be strictly controlled to ensure the integrity and strength of the weld. Deck welding requires not only a high level of technology, but also strict compliance with regulations and international standards to ensure that the welding quality meets the requirements of shipbuilding and maintenance. The deck is usually large in size, and positioning during welding is particularly critical. Deck welding in the existing technology is usually performed manually, but manual welding positioning is prone to deviations and the welding quality is poor. Using submerged arc welding can significantly improve the welding effect of the deck. Summary of the invention

The position of the weld is positioned by the two positioning pointers, and the adjusting knob is manually pressed down. The compression spring is compressed, so that the moving bevel gear engages with the rotating shaft bevel gear. At this time, turning the adjusting knob can drive the rotating shaft bevel gear and the lead screw bevel gear to rotate, thereby driving the internal threaded sleeve and the traverse seat to slide along the cross column rail through the rotation of the inner rotating shaft and the adjusting lead screw, thereby adjusting the position of the positioning pointer.

[0013] During the movement of the sliding frame, the recovery motor rotates to drive the motor bevel gear to rotate, thereby driving the middle bevel gear and the middle transmission wheel to rotate, and the upper transmission belt is driven to rotate through the upper transmission belt. At the same time, the middle transmission wheel drives the vertical shaft to rotate, and the upper transmission wheel rotates to drive the spiral shaft to rotate. The vertical shaft rotation drives the lower transmission wheel to rotate, and the right transmission wheel and the right gear are driven to rotate through the lower transmission belt, and the right lower wheel and the right collecting wheel are driven to rotate through the right transmission belt. The right gear drives the left gear and the left transmission wheel to rotate, and the left lower wheel and the left collecting wheel are driven to rotate through the left transmission belt.

The flux in the flux box 204 continuously falls from between the discharge pipe 207 and the welding wire pipe 208 onto the overtime weld, and the deck is welded through the conductive nozzle 209. When the sliding frame 201 stops moving, the flux will no longer fall out of the flux box 204 because the outlet of the discharge pipe 207 is full. During the movement of the sliding frame 201, the recovery motor 303 rotates to drive the motor bevel gear 304 to rotate, thereby driving the intermediate bevel gear 305 and the middle transmission wheel 306 to rotate, and the upper transmission belt 307 drives the upper transmission belt 307 to rotate.
