Specific Implementation Manner

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0030] As Figure 1 、 Figure 2 and Figure 3 shown, a butt joint limiting tooling and its rectangular steel pipe welding device include: a fixed plate 20, a movable plate 21 is arranged on the front wall surface of the fixed plate 20, the top of the fixed plate 20 is semi-capsule-shaped, and screw holes for installation are provided on the wall surface of the fixed plate 20. This is the prior art, so it will not be elaborated here.

[0031] AsFigure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a quick clamp structure is arranged on the top of the fixing plate 20 for fixing the steel pipe. The quick clamp structure includes: a base bar 30 and a clamp block 33. The base bar 30 is fixedly connected to the top of the fixing plate 20, and the clamp block 33 is symmetrically slidably connected to the top of the base bar 30.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the top of the movable plate 21 is also fixedly connected with the same base strip 30 and clamping block 33. The top of the clamping block 33 is sloped. The inclined surfaces of the symmetrical clamping blocks 33 at the top of each base strip 30 can form a V-shaped groove. The side wall surface of the clamping block 33 is evenly provided with a plurality of rectangular grooves. The quick clamping structure also includes an adapting groove 31 and a slider 32. The adapting groove 31 is opened through the top of the base strip 30. The slider 32 is symmetrically elastically connected in the adapting groove 31 through a spring. The bottom of the clamping block 33 is fixedly connected to the top of the slider 32. The adapting groove 31 is an L-shaped groove. The adapting groove 31 can adapt to the size of the slider 32. The adapting groove 31 is opened through The top and front wall of the base bar 30 are arranged, and the top and front wall of the slider 32 are flush with the top and front wall of the base bar 30 in the slider 32. The quick clamp structure also includes an adjustment plate 34, a groove 35 and a fixing bolt 36. The adjustment plate 34 is fixedly connected to the front wall of the slider 32, and the groove 35 is opened on the front wall of the base bar 30. The fixing bolt 36 is threadedly connected to the front wall of the adjustment plate 34. The fixing bolt 36 can penetrate the adjustment plate 34 and enter the groove 35. The wall surface of each slider 32 is provided with the same adjustment plate 34 and fixing bolt 36, and the wall surface of each base bar 30 is provided with a groove 35.

[0033] During specific use, the bottom of the fixing bolt 36 is not in the abutting groove 35 before use. First, the two sections of steel pipes to be welded are respectively placed between the symmetric clamping blocks 33 on the wall surface of the base strip 30 at the top of the fixing plate 20. When the steel pipes are placed between the symmetric clamping blocks 33, they will first be in the V-shaped groove formed at the top between the symmetric clamping blocks 33. At this time, the steel pipes are pressed down, and the inclined surfaces of the symmetric clamping blocks 33 will move simultaneously in two directions due to the pressure of the steel pipes. When the clamping blocks 33 move along the top of the base strip 30, the sliding blocks 32 will be driven by the clamping blocks 33 to slide in the fitting grooves 31. When the sliding blocks 32 move, the springs on their walls will be compressed. The sliding blocks 32 will drive the adjusting plate 34 and the fixing bolt 36 to slide along the wall surface of the base strip 30 when moving. When the steel pipes contact the top of the base strip 30, the symmetric clamping blocks 33 will clamp the steel pipes on the top of the base strip 30 due to the springs on the walls of the sliding blocks 32. At this time, the clamping of one section of the steel pipe is completed. If the worker feels that the clamping is not tight enough at this time, the position of the clamping block 33 can be fixed by screwing the fixing bolt 36 so that the bottom of the fixing bolt 36 passes through the adjusting plate 34 and is screwed into the abutting groove 35 and abuts against the wall surface in the abutting groove 35. The operation method of clamping the other section of the steel pipe at the top of the movable plate 21 is the same. After the steel pipes are welded, if the position of the clamping block 33 is fixed by the fixing bolt 36, first, the fixing bolt 36 needs to be screwed out of the abutting groove 35, and then the steel pipes can be directly removed from between the symmetric clamping blocks 33;

[0034] In summary, by setting the quick-clamping structure, the steel pipes can be clamped quickly. Because the quick-clamping structure is pushed by the springs through the symmetric clamping blocks 33 to quickly clamp the steel pipes on the device, the quick-clamping structure can also further fix the steel pipes by screwing the fixing bolt 36. The rectangular grooves on the walls of the clamping blocks 33 can also prevent the steel pipes from moving between the symmetric clamping blocks 33. Therefore, compared with the prior art, this solution is faster and more convenient when fixing steel pipes.

[0035] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, an adjustment structure is provided on the wall surface of the fixed plate 20. The adjustment structure includes a rotating groove 40, a base shaft 41, a connecting plate 42, and a locking groove 49. The rotating groove 40 is opened on the front wall surface of the fixed plate 20. The base shaft 41 is fixedly connected to the wall surface of the fixed plate 20 within the rotating groove 40. The connecting plate 42 is fixedly connected to the wall surface of the movable plate 21 facing the fixed plate 20. The locking groove 49 is opened at the top of the front wall surface of the fixed plate 20. A circular groove adapted to the size of the base shaft 41 is penetrated and opened at the top of the connecting plate 42. The circular groove on the wall surface of the connecting plate 42 is sleeved on the wall surface of the base shaft 41. The height of the connecting plate 42 is the same as that of the rotating groove 40. The adjustment structure further includes a spring groove 43, an adjustment block 44, a spring plate 45, a dial block 46, a dial groove 47, and a clamping strip 48. The spring groove 43 is opened at the top of the movable plate 21. The adjustment block 44 is slidably connected within the spring groove 43. The spring plates 45 are symmetrically and fixedly connected to the two side wall surfaces of the adjustment block 44. The spring plates 45 are also elastically connected within the spring groove 43 through springs. The dial block 46 is fixedly connected to the top of the adjustment block 44. The dial groove 47 is opened on the wall surface of the movable plate 21 at the top of the adjustment block 44. The clamping strip 48 is fixedly connected to the wall surface of the adjustment block 44 facing the rotating groove 40. The adjustment block 44 and the clamping strip 48 can penetrate from the wall surface of the movable plate 21 facing the fixed plate 20. The dial block 46 can slide within the dial groove 47. A plurality of locking grooves 49 are circularly arranged in an array on the arc surface of the fixed plate 20. The locking grooves 49 can be adapted to the size of the clamping strip 48. The clamping strip 48 can enter the locking grooves 49;

[0036] During specific use, when welding two steel pipes with an included angle, first, the dial block 46 is toggled in the opposite direction of the locking groove 49. When the dial block 46 is toggled, it will slide along the dial groove 47 and drive the adjustment block 44 to slide within the spring groove 43. The adjustment block 44 will drive the spring plates 45 to slide simultaneously. The springs on the wall surfaces of the spring plates 45 will be compressed. The adjustment block 44 can also drive the clamping strip 48 to separate from the locking groove 49. At this time, the rotation angle of the movable plate 21 can be adjusted. When the movable plate 21 rotates, the connecting plate 42 will also rotate simultaneously. When the movable plate 21 rotates, it will rotate around the base shaft 41 as the center. After the angle of the movable plate 21 is adjusted, the dial block 46 is released. At this time, the springs on the wall surfaces of the spring plates 45 will push the adjustment block 44 to move towards the locking groove 49. The adjustment block 44 will drive the clamping strip 48 to enter the locking groove 49 at the corresponding position to fix the angle of the movable plate 21. At this time, the steel pipes can be fixed on the tops of the fixed plate 20 and the movable plate 21 through the quick-clamping structure and welded;

[0037] In summary, by providing the adjustment structure, the fixed plate 20 and the movable plate 21 can be manually adjusted to the required rotation angle. Because the adjustment structure can rotate the movable plate 21 relative to the fixed plate 20 by an angle within 180 degrees, it can fix and weld two steel pipes into an included angle, thereby improving the applicability of the device.

[0038] A rectangular steel pipe welding device includes a frame body and a welding machine (not shown in the figure), and also includes all the above-mentioned butt joint limiting tools. The fixing plate 20 is fixedly connected to the top of the frame body;

[0039] During specific use, the fixing plate 20 is fixed to the top of the frame body through the screw holes opened on its wall surface. The movable plate 21 can slide on the top of the frame body. After the steel pipes are fixed by the butt joint limiting tools, the two sections of steel pipes can be welded by the welding machine;

[0040] In summary, by setting the butt joint limiting tools, the speed of the device during steel pipe welding can be increased, thereby improving its working efficiency and making the device have higher applicability.

[0041] Working principle: Before use, the bottom of the fixing bolt 36 is not in the abutting groove 35. First, place the two sections of steel pipes to be welded between the symmetric clamping blocks 33 on the wall surface of the base strip 30 at the top of the fixing plate 20. When the steel pipes are placed between the symmetric clamping blocks 33, they will first be in the V-shaped groove formed by the top of the symmetric clamping blocks 33. At this time, press down the steel pipes, and the inclined surfaces of the symmetric clamping blocks 33 will move in two directions simultaneously due to the pressure of the steel pipes. When the clamping blocks 33 move along the top of the base strip 30, the sliding blocks 32 will be driven by the clamping blocks 33 to slide in the fitting grooves 31. When the sliding blocks 32 move, the springs on their wall surfaces will be compressed. The sliding blocks 32 will drive the adjusting plate 34 and the fixing bolt 36 to slide along the wall surface of the base strip 30 when moving. When the steel pipes contact the top of the base strip 30, the symmetric clamping blocks 33 will clamp the steel pipes on the top of the base strip 30 due to the springs on the wall surfaces of the sliding blocks 32. At this time, the clamping of one section of the steel pipe is completed. If the worker feels that the clamping is not tight enough at this time, the fixing bolt 36 can be screwed to pass the bottom of the fixing bolt 36 through the adjusting plate 34 and screw it into the abutting groove 35 and abut against the wall surface in the abutting groove 35 to fix the position of the clamping block 33. The operation method of clamping the other section of the steel pipe on the top of the movable plate 21 is the same. After the steel pipe welding is completed, if the fixing bolt 36 fixes the position of the clamping block 33, first, the fixing bolt 36 needs to be screwed out of the abutting groove 35, and then the steel pipe can be directly taken off between the symmetric clamping blocks 33.
