Description

Technical Field

[0001] The present invention relates to the field of welding instruments, and particularly to an auxiliary positioning device for electric welding in building construction. Background Art

[0002] In building construction, I-beams, as a common structural steel, have good bearing capacity and bending strength. However, in complex building structures, simple I-beams may not meet all stability requirements. By connecting inclined steels to the two feet of the I-beam respectively, a more stable triangular support structure can be formed. This structure is more reasonable in mechanics and can effectively resist loads from all directions, improving the stability of the overall structure.

[0003] In welding, after the vertical steel frame is placed on the ground, the inclined steel frame is leaned against the side for welding. When the ground is uneven, the heights of the two welded inclined steel frames will be different, affecting the appearance. If the error is large, it will affect the structural strength. In addition, during welding, it needs to be held by hand, and both the vertical steel frame and the inclined steel frame are prone to tipping problems, which is inconvenient for welding operations.

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations

[0028] Such as Figures 1 - 8A kind of auxiliary positioning device for electric welding in building construction shown in the figure includes a bottom plate 1. A fixed clamping plate 2 is fixedly installed at the front of the upper surface of the bottom plate 1. A movable clamping plate 14 is installed at the rear of the upper surface of the bottom plate 1 through an adjusting mechanism. Two sliding openings 22 are penetrated through the middle of the upper surface of the bottom plate 1. A sliding plate 23 is slidably clamped inside the sliding openings 22. The upper end of the sliding plate 23 is fixedly connected with a limiting block 24. The two sliding plates 23 are controlled to move closer to or away from each other through a distance adjusting mechanism. A guide rail 3 is fixedly connected to the upper side of the fixed clamping plate 2. A sliding plate 4 is slidably sleeved on the outer surface of the guide rail 3. A limiting roller 6 is rotatably connected to the upper end of the sliding plate 4. Two adjusting plates 7 are installed at the front of the upper surface of the bottom plate 1 through a distance control mechanism. One side of the adjusting plate 7 is connected to the side surface of the sliding plate 4 through an elastic mechanism.

[0029] As Figure 4 、 Figure 5 shown in the figure, the distance control mechanism includes a fixed seat 27 fixedly installed on the lower surface of the bottom plate 1, and the fixed seat 27 is located on one side of the sliding opening 22. A threaded rod 26 is rotatably penetrated through one side of the fixed seat 27. The threaded rod 26 is threadedly penetrated through the inner sides of the two sliding plates 23. One end of the threaded rod 26 is fixedly connected with a rotating head 28. The rotating head 28 facilitates the user to rotate the threaded rod 26. The threaded rod 26 has symmetric threads on both sides of its surface. When rotating, the two sliding plates 23 will move closer to or away from each other.

[0030] As Figure 1 、 Figure 6 shown in the figure, a lower opening 21 is opened at the lower side of the movable clamping plate 14 and near the rotating head 28. A rear opening 20 is opened at the rear of the bottom plate 1 and near the rotating head 28. The designs of the lower opening 21 and the rear opening 20 are used to facilitate the user to rotate the rotating head 28.

[0031] As Figure 1 shown in the figure, the adjusting mechanism includes a first fixing plate 15 and a second fixing plate 16 fixedly installed at the rear of the upper surface of the bottom plate 1. The rear opening 20 is located between the first fixing plate 15 and the second fixing plate 16. A threaded column 17 is threadedly penetrated through the rear surface of the first fixing plate 15. The front end of the threaded column 17 is rotatably connected to the rear surface of the movable clamping plate 14. The rear end of the threaded column 17 is fixedly connected with a multi-faceted head 18. Guide columns 19 are respectively fixedly connected to both sides of the rear surface of the movable clamping plate 14. The two guide columns 19 respectively slide through the front surfaces of the first fixing plate 15 and the second fixing plate 16. The guide columns 19 are used to improve the stability of the movable clamping plate 14 when moving. The multi-faceted head 18 facilitates the user to rotate the threaded column 17 to control the movement of the movable clamping plate 14.

[0032] As Figure 5 、 Figure 6As shown, on one side of the upper surfaces of the two limiting blocks 24 that are close to each other, inclined guide surfaces 25 are respectively provided. The inclined guide surfaces 25 play a guiding role, enabling the lower end of the vertical steel frame 30 to be inserted downward and enter between the two limiting blocks 24 following the guidance of the inclined guide surfaces 25.

[0033] As Figure 2 、 Figure 3 shown, the elastic mechanism includes a guide rod 8 fixedly connected to the lower end of one side surface of the sliding plate 4. The guide rod 8 slidably passes through the side surface of the adjusting plate 7. The end of the guide rod 8 far from the sliding plate 4 is fixedly connected with a limiting head 9. A compression spring 10 is sleeved on the outer surface of the guide rod 8, and the compression spring 10 is located between the limiting head 9 and the adjusting plate 7. The limiting head 9 can prevent the compression spring 10 from slipping off from one end of the guide rod 8 and disengaging.

[0034] The distance control mechanism includes a fixed frame 12 fixedly installed at the front of the upper surface of the bottom plate 1. A lead screw 11 is rotatably penetrated through the inside of the fixed frame 12. The two ends of the lead screw 11 respectively threadedly penetrate through the side surfaces of the adjusting plate 7. A multi-angle sleeve 13 is fixedly sleeved at the middle of the outer surface of the lead screw 11, and the multi-angle sleeve 13 is located inside the fixed frame 12. The multi-angle sleeve 13 facilitates the user to rotate the lead screw 11. The lead screw 11 has symmetrically threaded sides on its surface, and can control the two adjusting plates 7 to move closer to or away from each other when rotated.

[0035] A connecting plate 5 is fixedly connected to the upper end of the side surface of the sliding plate 4. The front end of the limiting roller 6 is rotatably connected to the connecting plate 5. The limiting roller 6 can rotate to prevent scratching the surface when pushing the inclined steel frame 31.

[0036] As Figure 1 shown, on both sides of the lower surface of the bottom plate 1, pad elevating frames 29 are respectively fixedly installed. They are used to assist in arranging the bottom plate 1 at a certain height, facilitating the user's welding operation, and preventing difficult operation due to excessive bending.

[0037] The user places the vertical steel frame 30 between the two limiting blocks 24. During the placement process, the inclined guide surfaces 25 play a guiding role to ensure that the lower end of the vertical steel frame 30 can be smoothly inserted between the two limiting blocks 24. Then, the two inclined steel frames 31 are respectively arranged on both sides of the vertical steel frame 30. When inserting, the limiting roller 6 will be pushed, compressing the compression spring 10. After releasing the hand, the limiting roller 6 firmly abuts against the side surface of the inclined steel frame 31 to play a limiting role. Then, the user welds the connection position between the vertical steel frame 30 and the inclined steel frame 31 with a welding torch, which has the functions of guiding arrangement and limiting, bringing convenience to the welding process. When removing, the welded integral structure can be lifted, and the operation is convenient. The states of the arranged vertical steel frame 30 and inclined steel frame 31 are as Figure 7 、 Figure 8 shown. Since there is a gap between the vertical steel frame 30 and the inclined steel frame 31, the limiting blocks 24 will not be interfered.

[0038] By rotating the multi-sided head 18, the user causes the threaded column 17 to rotate, thereby causing the movable clamping plate 14 to move back and forth, ensuring that the lower ends of the vertical steel frame 30 and the inclined steel frame 31 can be tightly inserted between the movable clamping plate 14 and the fixed clamping plate 2, achieving a good limiting effect, so as to adapt to the use of vertical steel frames 30 and inclined steel frames 31 with different thicknesses, and having good adaptability.

[0039] By rotating the threaded rod 26, the user causes the two sliding plates 23 to move closer to or away from each other, so as to ensure that the lower end of the vertical steel frame 30 can be tightly inserted between the two limiting blocks 24. This part of the design can guide the arrangement position of the vertical steel frame 30 to be close to the middle of the bottom plate 1, and it can remain stable after being arranged. At the same time, the design of adjustable distance can adapt to the use of vertical steel frames 30 with different widths, and has better adaptability.

[0040] By rotating the multi-sided sleeve 13, the user causes the screw rod 11 to rotate, thereby causing the two adjusting plates 7 on both sides to move closer to or away from each other, and then changing the distance between the limiting roller 6 and the inclined steel frame 31, ensuring that the limiting roller 6 can closely adhere to the surface of the inclined steel frame 31, and also ensuring that the limiting roller 6 will not hinder the upward removal of the inclined steel frame 31 due to excessive squeezing.
