[0017] Please see Figures 1-2 In this embodiment, a welding fixture for shipbuilding includes a base plate 1. A placement platform 2 is fixedly installed at the top center of the base plate 1. Baffles 3 are fixedly installed on the back and right side of the placement platform 2. Pushing mechanisms 4 are provided on the left side and front side of the placement platform 2. A flip plate 5 is rotatably installed at the top front end of the placement platform 2. A number of horizontal plates 6 are fixedly installed on the back of the flip plate 5. A positioning hole 7 is opened at the top center of the horizontal plate 6. A fixing mechanism 8 is provided on the flip plate 5.

[0018] In this embodiment, the pushing mechanism 4 includes an L-shaped plate 41, a hydraulic push rod 42, and a pushing plate 43. The L-shaped plate 41 is fixedly installed on the left side and the front side of the placement platform 2. The hydraulic push rod 42 is embedded in the L-shaped plate 41, and the pushing plate 43 is fixedly installed on the output end of the hydraulic push rod 42.

[0019] Specifically, after the deck to be welded is hoisted onto the placement platform 2, the hydraulic push rods 42 on both sides are operated to bring the push plate 43 close to the deck, so that the back and right side of the deck can be attached to the baffles 3 on both sides, which can be used to position the deck and facilitate the precise welding of the deck longitudinals.

[0020] In this embodiment, mounting plates 51 are fixedly installed on both the left and right ends of the top of the front L-shaped plate 41. The flip plate 5 is rotatably installed between the two mounting plates 51. A connecting shaft 52 is rotatably installed on the left side of the left mounting plate 51. The right end of the connecting shaft 52 passes through the mounting plate 51 and is fixedly connected to the flip plate 5. A driven gear 53 is fixedly installed on the left side of the connecting shaft 52. A motor frame 54 is fixedly installed on the front of the left mounting plate 51. A drive motor 55 is fixedly installed on the left side of the motor frame 54. A drive gear 56 is fixedly installed at the output end of the drive motor 55. The drive gear 56 meshes with the driven gear 53.

[0021] Specifically, when the drive motor 55 is turned on, it rotates the drive gear 56. The drive gear 56 transmits power to the driven gear 53, which drives the flip plate 5 to flip, allowing the flip plate 5 to be lowered or raised.

[0022] In this embodiment, the fixing mechanism 8 includes a movable plate 81, a connecting rod 82, a first clamping plate 83, a push rod frame 84, an electric push rod 85, and a second clamping plate 86. The movable plate 81 is slidably installed above the flip plate 5. A connecting rod 82 extending to the top of the horizontal plate 6 is fixedly installed on the back of the movable plate 81. The first clamping plate 83 is fixedly installed on the back of the connecting rod 82. A push rod frame 84 is fixedly installed at the top right end of the flip plate 5. An electric push rod 85 whose output end is fixedly connected to the movable plate 81 is fixedly installed on the left side of the push rod frame 84. The second clamping plate 86 is fixedly installed at the top right end of the horizontal plate 6.

[0023] Specifically, the longitudinal rib of the deck to be welded is placed in the positioning hole 7, and the electric push rod 85 is operated to move the moving plate 81 to the right. The moving plate 81 drives the first clamping plate 83 to move to the right and fit tightly against the longitudinal rib of the deck, thereby fixing it between the first clamping plate 83 and the second clamping plate 86. In this way, the workpiece displacement can be avoided during the welding process, which helps to improve the accuracy of the workpiece welding.

[0024] In this embodiment, a groove is provided at the top center of the flip plate 5, and a slider with one end fixedly connected to the moving plate 81 is slidably installed inside the groove.

[0025] Specifically, the arrangement of the groove and slider allows the moving plate 81 to slide on the flip plate 5.

[0026] The working principle of the above embodiments is as follows:

[0027] (1) Hoist the deck to be welded onto the placement platform 2, and operate the hydraulic push rods 42 on both sides to push the push plate 43 close to the deck so that the back and right sides of the deck can be attached to the baffles 3 on both sides respectively.

[0028] (2) Turn on the drive motor 55 to rotate the drive gear 56. The drive gear 56 transmits power to the driven gear 53. The driven gear 53 drives the flip plate 5 to flip, so that the flip plate 5 can move from the upright state to the top of the deck. At this time, the position of the positioning hole 7 on the deck is the installation position of the deck longitudinal skeleton.

[0029] (3) Place the longitudinal skeleton of the deck to be welded into the positioning hole 7, operate the electric push rod 85 to move the moving plate 81 to the right, the moving plate 81 drives the first clamping plate 83 to move to the right and stick to the longitudinal skeleton of the deck, thereby fixing it between the first clamping plate 83 and the second clamping plate 86.

[0030] (4) Use a welding torch to weld the deck to the deck longitudinal skeleton.
