[0021] In this embodiment: During welding, the first shaping splint 3 and the second positioning clamping plate 20 cooperate with each other to clamp the H-shaped steel plate to be spliced. The fixing clamping plate 10 is adjusted so that the fixing clamping plate 10 clamps onto the flange of the H-shaped steel plate, thereby fixing and positioning the device onto the H-shaped steel plate. Then, the H-shaped steel plate to be spliced is clamped into the clamping cavity formed between the second shaping splint 5 and the second positioning clamping plate 20. At the same time, the fixing clamping plates 10 provided on the second shaping splint 5 and the second positioning clamping plate 20 are adjusted to clamp onto the flange of the clamped H-shaped steel plate. The electric retractable rod 15 is activated, and the second shaping splint 5 and the first positioning clamping plate 19 connected to one end correspondingly by the contraction of the electric retractable rod 15 slide synchronously towards the direction of the first shaping splint 3 and the second positioning clamping plate 20. During the sliding process, the first pulling plate 4 and the second pulling plate 12 will slide along the corresponding position of the first shaping splint 3 towards one end, which is beneficial to preventing the position of the H-shaped steel plate from shifting during the sliding process. At this time, the clamped H-shaped steel plate will slide steadily and quickly towards the H-shaped steel plate to be spliced under the action of the auxiliary roller rod 2, so that the splicing interfaces of the spliced H-shaped steel plates are clamped together. At this time, the spliced interfaces can be welded.
[0022] Please refer particularly to Figure 1 , Figure 2 and Figure 3 , a lifting guide cavity 6 is provided in the middle of the outer surface of one side of the first shaping splint 3, the second shaping splint 5, the first positioning clamping plate 19 and the second positioning clamping plate 20. One side of the fixing clamping plate 10 is slidably connected to the lifting guide cavity 6. A sliding rod 11 is slidably connected to the middle of the inner side of the fixing clamping plate 10. A regulating gear rod 7 is provided in the middle of one side of the lifting guide cavity 6. One tooth plate 8 is meshed and connected to the left and right ends of one side of the regulating gear rod 7. One tooth plate 9 is meshed and connected to the left and right ends of the other side of the regulating gear rod 7. The lower part of the tooth plate 8 is fixedly connected to the fixing clamping plate 10 located below one side of the lifting guide cavity 6. The upper part of the tooth plate 9 is fixedly connected to the fixing clamping plate 10 located above one side of the lifting guide cavity 6. Support connecting blocks are provided at the left and right ends of the regulating gear rod 7. One side of the support connecting block is fixedly connected to the middle of the left and right ends of the outer surface of one side of the first shaping splint 3 or the second shaping splint 5 or the first positioning clamping plate 19 or the second positioning clamping plate 20. A first chute 13 is provided at the bottom of the second shaping splint 5. The first chute 13 is provided at one end of the front side of the upper surface of the base plate 1. A second chute 14 is provided at the bottom of the first shaping splint 3. The second chute 14 is provided at the other end of the front side of the upper surface of the base plate 1. A first flange 16 is provided below the clamping cavity formed between the second shaping splint 5 and the first positioning clamping plate 19. The middle of the top of the first flange 16 is provided with a web 17. The top of the web 17 is provided with a second flange 18.
[0023] In this embodiment: Before use, the staff manually pulls the second retractable plate 12 forward. The second retractable plate 12 drives the second shaping clamp plate 5 provided at one end of the second retractable plate 12 and the first shaping clamp plate 3 provided at the other end of the second retractable plate 12 to slide forward along the corresponding first chute 13 and second chute 14 respectively, synchronously increasing the distances between the second shaping clamp plate 5 and the first positioning card plate 19 and between the first shaping clamp plate 3 and the second positioning card plate 20. The fixed H-shaped steel plate is clamped in front of the second positioning card plate 20, and the movable H-shaped steel plate to be bottled is clamped in front of the first positioning card plate 19, so that the lower surface of the first wing plate 16 fits against the upper surface of the auxiliary roller rod 2. At this time, the staff pushes the second retractable plate 12 backward to drive the second shaping clamp plate 5 and the first shaping clamp plate 3 to slide backward along the corresponding first chute 13 and second chute 14 to reset. When the outer surfaces on one side of the second shaping clamp plate 5 and the first shaping clamp plate 3 are synchronously clamped onto the outer surfaces on one side of the first wing plate 16 and the second wing plate 18, the pushing of the second retractable plate 12 is stopped. Then, the adjusting gear rod 7 is rotated in sequence. The adjusting gear rod 7 drives the engaged first toothed plate 8 to slide downward and the engaged second toothed plate 9 to slide upward. The downward-sliding first toothed plate 8 drives the fixed clamp plate 10 fixedly connected to the bottom end to slide downward and clamp onto one end of the upper surface of the first wing plate 16. The suction cup provided below the fixed clamp plate 10 sucks and clamps onto the first wing plate 16 to fix the position of the first wing plate 16. The upward-sliding second toothed plate 9 drives the fixed clamp plate 10 fixedly connected above to slide upward and clamp onto the lower surface of the second wing plate 18, so that the suction cup provided on the upper surface of the fixed clamp plate 10 adsorbs and fixes onto the lower surface of the second wing plate 18 to fix the position of the second wing plate 18. Thus, the fixed H-shaped steel plate and the movable H-shaped steel plate can be synchronously clamped and positioned. When the electric retractable rod 15 drives the clamped H-shaped steel plate to move towards the fixed H-shaped steel plate through the second shaping clamp plate 5 and the first positioning card plate 19, the fixed clamp plate 10 provided on the second shaping clamp plate 5 and the first positioning card plate 19 slides along the sliding cavity in the middle of the fixed clamp plate 10 provided on the first shaping clamp plate 3 and the second positioning card plate 20 under the guidance of the sliding rod 11 fixedly connected to the middle of one end, which is beneficial to preventing the H-shaped steel plate from shaking during the process of sliding and splicing towards one end;
[0024] During the up and down sliding process of the fixed clamp plate 10, it slides along the lifting guide cavity 6, which is beneficial to preventing the fixed clamp plate 10 from shaking or shifting during the up and down sliding process.
[0025] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
