[0028] The replacement mechanism includes groove plates 10 respectively fixedly mounted on the outer sides of the turret plates 2, and replaceable arc-shaped resisting members 8 are movably mounted on the upper surfaces of the two turret plates 2. Two threaded connectors 11 are fixedly mounted on the lower surfaces of the replaceable arc-shaped resisting members 8, and each threaded connector 11 is movably mounted on the inner side of the groove plate 10. The outer surface of the threaded connector 11 is threadedly matched with a nut 12, and the nut 12 is movably mounted under the groove plate 10, so as to facilitate the replacement of the replaceable arc-shaped resisting members 8. By rotating the nut 12, replaceable arc-shaped resisting members 8 of different models can be replaced through the threaded connector 11, so that the steel plate fits the replaceable arc-shaped resisting members 8, so that different models of ship decks can be assembled.

[0029] The frame mechanism includes two movable grooves 3 opened in the front and back of each rotating frame plate 2, and a rotating shaft 4 is movably installed in the two horizontal movable grooves 3. A servo motor 5 is fixedly installed on one side of the rear end rotating shaft 4, and a pad plate 6 is fixedly installed on the lower surface of the servo motor 5, and the pad plate 6 is fixedly installed on the upper surface of the pressure dividing plate 1. A track 7 is commonly sleeved on the outer side of the two rotating shafts 4. The rear end rotating shaft 4 is driven to rotate forward or backward by the servo motor 5, and the front end rotating shaft 4 is driven to rotate together by the track 7, so as to control the track 7 to drive the upper steel plate to move forward or backward, and cooperate with the brazing gun 25 to complete the brazing operation.

The brazing gun 25 is driven to move vertically by the vertical telescopic cylinder 21, and the vertical guide cylinder 22 cooperates with the vertical guide rod 23 to prevent the brazing gun 25 from rotating during the vertical movement process.

[0034] The pushing mechanism includes an extended connecting piece 31 fixedly installed on the inner side of the rear ends of the two pressure dividing plates 1, a second supporting piece 32 is fixedly installed on the upper surface of the extended connecting piece 31, a second telescopic cylinder 33 is fixedly installed on the front surface of the second supporting piece 32, a second push plate 34 is fixedly installed on the front surface of the second telescopic cylinder 33, and the second push plate 34 is movably installed on the upper surface of the track 7. The second push plate 34 is pushed forward by the second telescopic cylinder 33 to make the steel plates tighter and facilitate brazing, and the movement of the second push plate 34 is limited by the track 7 to prevent the second push plate 34 from rotating during movement.

[0036] During use, different types of replaceable arc-shaped abutments 8 are replaced by threaded connectors 11 and nuts 12, so as to assemble different types of ship decks.

The second telescopic cylinder 27 is used to move the first push plate 28 horizontally to squeeze the steel plates inward to the abutment 30, so that there is no gap between every two steel plates. The retracting cylinder 33 moves the second push plate 34 to squeeze the steel plate forward to the replaceable arc-shaped abutment 8, so as to fit the ship type that needs to be brazed. The sliding table 19 and the L plate 20 are driven by the transverse motor 17 and the rotating shaft 18 to move transversely to the opposite position of the steel plate for brazing. The vertical telescopic cylinder 21 moves the brazing gun 25 vertically for brazing. The servo motor 5 drives the crawler 7 to move forward to cooperate with the vertical brazing. After completing the welding of a butt seam, the brazing gun 25 is retracted by the vertical telescopic cylinder 21, and the servo motor 5 drives the crawler 7 to move backward. Reset, repeat the operation by the traverse motor 17, the vertical telescopic cylinder 21, and the brazing gun 25 until the row of steel plates is completely welded, and continue to place a row of steel plates on the crawler 7 through the robot arm, repeat the second push plate 34 and the first push plate 28 to squeeze the row of steel plates, so that there is no gap between the current layer of steel plates and the upper layer of steel plates, and there is no gap between the current layer of steel plates. At this time, the brazing gun 25 is aimed at the right side of the seam between the first layer and the second layer, and is moved horizontally by the traverse motor 17 to the current layer of steel plates and the upper layer of steel plates. At the end of the seam, the vertical telescopic cylinder 21 is moved vertically, and the seam is transversely brazed by the transverse motor 17. After the brazing is completed, the vertical brazing operation is repeated by the transverse motor 17, the vertical telescopic cylinder 21, the servo motor 5, and the brazing gun 25.
