The controller 6 is located on the rear side of the top of the base plate 1.

[0024] Please refer to Figures 3-4. The side pressure mechanism 4 includes a cylinder seat 41, a cylinder 42, and a movable block 43. The cylinder seat 41 is located on the top rear side of the base plate 1. The cylinder 42 is located on the rear side of the cylinder seat 41. The movable end of the cylinder 42 passes through the cylinder seat 41 and is fixedly connected to the movable block 43.

[0025] The pressing mechanism 5 includes a connecting rod 51, a straight rod 52, a push rod seat 53, an electric push rod 54, and a pressing mechanism 55. The bottom of the connecting rod 51 is rotatably connected to the top of the side pressing mechanism 4 via a rotating shaft. The top of the connecting rod 51 passes through the top of the bracket 2 and is rotatably connected to the right end of the straight rod 52 via a rotating shaft. The left end of the straight rod 52 is fixedly connected to the push rod seat 53. The top of the push rod seat 53 is provided with an electric push rod 54. The movable end of the electric push rod 54 passes through the push rod seat 53 and is fixedly connected to the top of the pressing mechanism 55.

[0026] Cylinder 42 is horizontally positioned;

[0027] The electric actuator 54 is vertically positioned, and the actuator seat 53 is fitted over the electric actuator 54.

[0028] Please refer to Figure 5. The pressurizing mechanism 55 includes a pressurizing mechanism base plate 551, a pressure sensor 552, a limiting rod 553, a pressurizing mechanism top plate 554, and a spring 555. The pressure sensor 552 is located in the middle of the pressurizing mechanism base plate 551. The pressure sensor 552 is used to detect the downward pressure on the clamped workpiece. The limiting rod 553 is located on the top left and right sides of the pressurizing mechanism base plate 551. The pressurizing mechanism top plate 554 is elastically connected to the pressurizing mechanism base plate 551 through the spring 555.

[0030] In use, two steel sections to be welded are placed on top of the base plate 1 from the left and right ends. The controller 6 controls the extension of the movable end of the cylinder 42, which pushes the movable block 43 forward. The movable block 43 drives the connecting rod 51 forward, causing the connecting rod 51 to rotate clockwise along the rotation axis at the top of the movable block 43. The connecting rod 51 drives the straight rod 52 downward, which in turn drives the push rod seat 53 downward. This causes the push rod seat 53 to drive the electric push rod 54 downward, causing the pressing mechanism 5, which is fixedly connected to the movable end of the electric push rod 54, to press the steel section downward. The top plate 554 of the pressing mechanism presses the spring 5 downward along the downward limit rod 553. 55, thereby pressurizing the base plate 551 of the pressurizing mechanism. At the same time, the cylinder 42 pushes the movable block 43 to clamp the steel section between the fixed block 3 in the left and right directions. When the cylinder 42 clamps the steel section between the movable block 43 and the fixed block 3, the pressure sensor 552 detects the downward pressure of the base plate 551 of the pressurizing mechanism on the steel section. If the downward pressure is too small, the movable end of the electric push rod 54 is extended to apply downward pressure to the top plate 554 of the pressurizing mechanism, thereby increasing the downward pressure of the base plate 551 of the pressurizing mechanism on the steel section, so that the steel section remains stable and does not shake, preventing the steel section from deforming during welding. Then the worker welds the steel section between the two supports 2.
