Description

Technical Field

[0002] The bottom plate frame is a component composed of the bottom plate and the frame. By welding the frame to the bottom plate, the stability and maximum bearing capacity of the hull are improved.

[0003] A Chinese patent discloses a welding device for ship steel structure production, with the publication number CN115319359A, comprising a supporting base plate, a processing table fixedly connected to the upper surface of the supporting base plate, a mobile bracket slidably connected inside the processing table, a control panel fixedly connected to the front surface of the mobile bracket, and a servo motor fixedly connected to the side of the mobile bracket away from the control panel; the present invention solves the existing problems of large installation errors and offsets of existing welded steel plates through the mutual cooperation between the set centering mechanism and the internal parts of the equipment, and performs transverse correction on the middle welded steel plate through the clamping plate and the limit plate. Since the force is mutual, the centering plates on both sides perform centering treatment on the middle welded steel plate, so the welded steel plate is corrected longitudinally, and the welded steel plate is centered in both the transverse and longitudinal directions, so the effect of centering the welded steel plate is achieved.

[0004] However, it still has the following disadvantages: the device starts the servo motor to drive the gear plate to rotate, so that the gear plate rolls along the single-sided tooth plate to achieve the effect of controlling the forward and backward movement of the welding head, but the welding pen moves in a straight line, resulting in a narrow weld and low strength of the welding part.
