[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 A steel section welding machine in this embodiment includes a support platform 1, a support mechanism 2 for providing stable support is provided in the middle of the upper surface of the support platform 1, and clamping mechanisms 3 for clamping the steel section are provided at the left and right ends of the inner cavity of the support platform 1. Dual-axis linear modules 4 are fixed at the left and right ends of the upper surface of the support platform 1, and welding heads 5 are fixed on the opposite sides of the two dual-axis linear modules 4.

[0030] In this embodiment, four support bases are fixed to the lower surface of the support platform 1 , and the four support bases are evenly distributed on the lower surface of the support platform 1 .

[0031] See also Figures 2 to 3 In order to limit the vertical position of the C-shaped steel during welding, the support mechanism 2 in this embodiment includes four support plates 21, four connecting seats 22, two connecting rods 23, four No. 1 rotating rollers 24, a top frame 25, an electric push rod 26, a movable plate 27, a mounting frame 28 and a No. 2 rotating roller 29. The four support plates 21 are fixed to the front and rear sides of the left and right ends of the upper surface of the support platform 1, the four connecting seats 22 are respectively fixed to the upper surfaces of the four support plates 21, the connecting rod 23 is rotatably connected between the opposite sides of the left and right connecting seats 22 through a bearing, the No. 1 rotating roller 24 is fixed to the outer surface of the connecting rod 23, the top frame 25 is fixed to the upper surface of the support platform 1, and the electric push rod 26 is fixed to the upper surface of the support platform 1. The rod 26 is fixed to the upper surface of the top frame 25, and one end of the two C-shaped steels is aligned and placed on the upper surface of the four No. 1 rotating rollers 24. Then the electric push rod 26 is started, and the piston rod of the electric push rod 26 moves downward, which can push the movable plate 27 to move downward. The movable plate 27 is arranged in the inner cavity of the top frame 25, and the mounting frame 28 is fixed in the middle of the lower surface of the movable plate 27. The No. 2 rotating roller 29 is rotatably connected between the opposite sides of the left and right side walls of the inner cavity of the mounting frame 28 through a bearing. The downward movement of the movable plate 27 can drive the mounting frame 28 to move downward until the No. 2 rotating roller 29 in the inner cavity of the mounting frame 28 is pressed against the upper surface of the C-shaped steel, so as to position the two C-shaped steels in the vertical direction.

[0032] Among them, the two support plates 21 are symmetrically distributed on the left and right sides of the vertical central axis of the support platform 1, the two No. 1 rotating rollers 24 are symmetrically distributed on the left and right sides of the vertical central axis of the connecting rod 23, the cross-sectional shapes of the top frame 25 and the mounting frame 28 are both inverted U-shaped, and the piston rod of the electric push rod 26 passes through the top frame 25 and extends to the inner cavity of the top frame 25 and is fixed to the movable plate 27.

[0033] In this embodiment, load-bearing plates are fixed on the upper and lower sides of the left and right ends of the back side of the top frame 25, and limiting rods are fixed on the opposite sides of the upper and lower load-bearing plates. Limiting sleeves are fixed on the left and right ends of the back side of the movable plate 27, and the limiting sleeves are slidably connected to the outer surface of the limiting rod. When the movable plate 27 moves, the limiting sleeves fixed on the left and right ends of its back side slide downward on the outer surface of the limiting rod, which can limit the movement of the movable plate 27.

[0034] See also Figure 4In order to limit the horizontal position of the C-shaped steel during welding, the clamping mechanism 3 in this embodiment includes a screw 31, a screw sleeve 32, a connecting plate 33, a support frame 34, two connecting frames 35 and two No. 3 rotating rollers 36. The screw 31 is rotatably connected between the left and right side walls of the inner cavity of the support platform 1 through a bearing. The screw sleeve 32 is threadedly connected to the screw 31. The connecting plate 33 is provided on the upper surface of the support platform 1 and the lower surface passes through the support platform 1 and is fixed to the screw sleeve 32. The rotation of the screw 31 causes the screw sleeve 32 threadedly connected to its surface to move, and the movement of the screw sleeve 32 drives the connecting plate 3 3 moves, the support frame 34 is fixed to the upper surface of the connecting plate 33, and the two connecting frames 35 are fixed to the front and rear sides of the upper surface of the support frame 34. The opposite sides of the left and right connecting frames 35 are each provided with an inverted U-shaped groove, and the third rotating roller 36 is rotatably connected between the top wall and the opposite side of the inner bottom wall of the inverted U-shaped groove through a bearing. The movement of the connecting plate 33 causes the support frame 34 and the connecting frame 35 to move, and at this time, the two connecting frames 35 perform relative movement until the four third rotating rollers 36 at the left and right ends are respectively attached to and squeezed against the left and right sides of the C-shaped steel, thereby positioning the C-shaped steel in the horizontal direction.

[0035] Among them, sliding bars are fixed on the left and right ends of the inner bottom wall of the support platform 1, and a slider is fixed on the lower surface of the screw sleeve 32. The slider makes horizontal linear motion in the inner cavity of the sliding bar. When the screw sleeve 32 moves, the slider fixed on its lower surface moves in the inner cavity of the sliding bar, which can limit the movement of the screw sleeve 32, so that the screw sleeve 32 can only move linearly. The two connecting frames 35 are symmetrically distributed on the front and rear sides of the horizontal central axis of the support frame 34. The opposite sides of the two screws 31 pass through the support platform 1 and extend to the side away from the support platform 1 and are fixed with handles.

[0036] It should be noted that the support mechanism 2 is set so that the vertical displacement of the C-shaped steel remains unchanged during welding, and the clamping mechanism 3 is set so that the horizontal displacement of the C-shaped steel remains unchanged during welding, ensuring the stability of the two C-shaped steels during movement and improving the welding effect of the C-shaped steel.

[0037] It can be understood that the position of the welding head 5 can be adjusted by the dual-axis linear module 4, so that the welding of two C-shaped steels can be carried out, pushing the C-shaped steel forward, and the No. 1 rotating roller 24, the No. 2 rotating roller 29 and the No. 3 rotating roller 36 all rotate, thereby ensuring the stability of the two C-shaped steels during movement, avoiding the deviation of the C-shaped steels, and achieving better welding effect.

[0038] The working principle of the above embodiment is:

[0039] (1) When welding two C-shaped steels, first align one end of the two C-shaped steels and place them on the upper surface of the four No. 1 rotating rollers 24, then start the electric push rod 26, and the piston rod of the electric push rod 26 moves downward, which can push the movable plate 27 to move downward. When the movable plate 27 moves, the limit sleeves fixed on the left and right ends of the back of the movable plate 27 slide downward on the outer surface of the limit rod, which can limit the movement of the movable plate 27. The downward movement of the movable plate 27 can drive the mounting frame 28 to move downward until the No. 2 rotating roller 29 in the inner cavity of the mounting frame 28 is pressed against the upper surface of the C-shaped steel, which can position the two C-shaped steels in the vertical direction.

[0040] (2) Then rotate the handles on both sides to rotate the screw rod 31. The rotation of the screw rod 31 causes the screw sleeve 32 connected to its surface to move. When the screw sleeve 32 moves, the slider fixed on its lower surface moves in the inner cavity of the slide bar, which can limit the movement of the screw sleeve 32, so that the screw sleeve 32 can only move linearly. The movement of the screw sleeve 32 drives the connecting plate 33 to move. The movement of the connecting plate 33 causes the support frame 34 and the connecting frame 35 to move. At this time, the two connecting frames 35 move relative to each other until the four No. 3 rotating rollers 36 at the left and right ends are respectively attached to and squeezed on the left and right sides of the C-shaped steel, so that the horizontal direction of the C-shaped steel can be positioned. Then, the position of the welding head 5 can be adjusted by the double-axis linear module 4, so that the two C-shaped steels can be welded and pushed forward. The No. 1 rotating roller 24, the No. 2 rotating roller 29 and the No. 3 rotating roller 36 all rotate, thereby ensuring the stability of the two C-shaped steels when moving.
