[0002] Steel structure welding is a process that connects metal components by melting them at high temperatures. It is widely used in the fields of construction, bridges, shipbuilding, etc. It uses the heat generated by electric arcs, gas flames or other heat sources to partially melt the metal, and at the same time, add or not add filler materials. After cooling, a strong weld is formed to ensure the stability and bearing capacity of the structure. During the welding process, welding parameters such as current, voltage and welding speed need to be precisely controlled to ensure that the quality of the weld meets the design and safety requirements.

[0027] The disclosed embodiments are intended to solve the problem that existing clamping brackets can usually only clamp steel structures of the same shape, such as steel plate clamping brackets. When a steel pipe needs to be clamped, the clamping bracket needs to be replaced, or the welding machine needs to be replaced. This approach reduces the universality of the clamping device and also reduces welding efficiency. In view of this, the disclosed embodiments propose a clamping bracket for steel structure welding, which provides a new clamping device, provides clamping grooves in the clamping device, and clamps columnar steel structures through clamping grooves of different diameters, thereby achieving the same clamping block being able to clamp both plate-shaped steel structures and columnar steel structures, avoiding the need to replace the clamping device for steel structures of different shapes, improving the universality of the clamping device, and also improving welding efficiency.
[0028] like Figures 1 to 7 As shown, a clamping bracket for steel structure welding includes a bracket body 1, a control unit 2 and a moving mechanism 3. The bracket body 1 is fixed, the control unit 2 is mounted on the bracket body 1, and the moving mechanism 3 is mounted on the bracket body 1; it is characterized in that a clamping device 4 is mounted on the moving mechanism 3, and the clamping device 4 is used to perform adaptive clamping according to steel structures of different shapes, thereby achieving better welding work;
[0029] The above-mentioned clamping device 4 can be used to clamp steel structures of different shapes, so that the same clamping block 41 can clamp both plate-shaped steel structures and columnar steel structures, avoiding the need to replace the clamping device 4 when facing steel structures of different shapes, improving the universality of the clamping device 4, and also improving welding efficiency.
[0030] like Figures 1 to 5As shown, the clamping device 4 includes a clamping block 41, an anti-slip groove 42 and a clamping groove 43. Two clamping blocks 41 are symmetrically installed on the moving mechanism 3, and the clamping blocks 41 are used to clamp the steel structure; the clamping blocks 41 are respectively installed with corresponding anti-slip grooves 42 in opposite directions, and the anti-slip grooves 42 are used to increase the friction between the steel structure and the clamping block 41 when clamping the steel plate, thereby achieving clamping of the plate-like steel structure; the clamping grooves 43 are installed in an array on the clamping block 41, and the clamping grooves 43 are used to clamp the columnar steel structure;
[0031] During operation, when it is necessary to clamp a plate-shaped steel structure, the two clamping devices 4 can be controlled to contract by the cylinder, so that the two clamping blocks 41 clamp the two steel plates for welding. At the same time, due to the design of the anti-slip grooves 42 on the clamping blocks 41, the friction between the steel structure and the clamping blocks 41 can be increased; when it is necessary to clamp a columnar steel structure, it is only necessary to place the columnar steel structure in the clamping groove 43. At this time, due to the presence of the rubber pad 44 in the clamping groove 43 and the clamping telescopic rod 45 in the large-diameter clamping groove 43, the columnar steel structure can be well fixed, thereby avoiding the need to replace the clamping device 4 when facing steel structures of different shapes.
[0032] like Figure 3 As shown, there are six clamping grooves 43 and their diameters gradually increase. The above method is suitable for clamping columnar steel structures of different diameters; and this method can quickly position the columnar steel structure. At the same time, the clamping grooves 43 can also be used to rotate it during welding, that is, when the welding position needs to be changed, it is only necessary to slightly loosen the clamping plate and rotate it to change the welding position to achieve welding work around the columnar steel structure.
[0033] like Figure 4 and Figure 5 As shown, rubber pads 44 are installed in the three clamping grooves 43 at the front end, and the rubber pads 44 are used to increase the friction between the clamping grooves 43 and the cylindrical steel structure; the three clamping grooves 43 at the rear end are provided with a circular array of clamping telescopic rods 45, and the clamping telescopic rods 45 are used to make fine adjustments according to cylindrical steel structures of different diameters; one end of the clamping telescopic rods 45 is hinged with a clamping piece 46, and the clamping piece 46 is used to make adaptive adjustments when contacting the cylindrical steel structure; a pressure spring 47 is provided between the clamping telescopic rods 45 and the clamping block 41, and the pressure spring 47 is used to squeeze the cylindrical steel structure to fix it;
[0034] For the clamping groove 43 with a smaller diameter, a rubber pad 44 can be installed inside it to achieve its fixation, and then it can be welded; while for the last three clamping grooves 43, due to their larger diameters, the rubber pad 44 cannot be used to fix them stably during the clamping process, so the telescopic rod and the pressure spring 47 are used in combination to achieve their quick fixation; and then they can be just welded.
[0035] like Figure 6 As shown, a rotating disk 5 for changing the direction of the clamping block 41 is installed under the moving mechanism 3. When the columnar steel structure needs to be welded, since the clamping method of the clamping plate is lateral clamping, the rotating disk 5 is required to rotate the clamping device 4, thereby changing the direction of the clamping device 4, and then the columnar steel structure is placed in for welding. In this way, welding of steel structures of different lengths can be achieved, and at the same time, the clamping device 4 has higher adaptability.
[0036] like Figure 7 As shown, on the same clamping block 41, the upper and lower clamping pieces 46 in the middle are provided with laser transmitters and receivers 6, which are used to cooperate with the laser transmitters and receivers 6 to achieve the centering work before welding; on the other clamping block 41, the upper and lower clamping pieces 46 in the middle are provided with laser transmitters and receivers 6, which are used to receive signals from the laser transmitters and receivers 6;
[0037] Since the large-diameter columnar steel structure is clamped using a clamping telescopic rod 45, and since there are six clamping telescopic rods 45, laser transmitters and receivers 6 are mounted on two clamping plates 46 perpendicular to the clamping plate, and a laser transmitter and receiver 6 is also mounted on the clamping plate 46 on the other clamping mechanism. When a laser transmitter and receiver 6 cannot receive a signal from another laser transmitter and receiver 6, it proves that the two columnar steel structures are not well aligned. If welding is performed at this time, it will cause misalignment, thereby affecting the welding effect. When different laser transmitters and receivers 6 are aligned, it proves that the two steel structures are basically aligned, and the welding effect can be guaranteed when welding them.
[0038] During operation, when it is necessary to clamp a plate-shaped steel structure, the two clamping devices 4 can be controlled to contract by the cylinder, so that the two clamping blocks 41 clamp the two steel plates for welding. At the same time, due to the design of the anti-slip grooves 42 on the clamping blocks 41, the friction between the steel structure and the clamping blocks 41 can be increased. After clamping is completed, the plate-shaped steel structure can be directly welded by the welding gun.
[0039] When it is necessary to weld a columnar steel structure, the control unit 2 first controls the rotating disk 5 through the power unit to drive the clamping device 4 to rotate, and then places the columnar steel structure on the rotated clamping device 4, and then closes the two clamping blocks 41. During the closing process, the steel structure will apply pressure to the rubber pad 44 or the clamping telescopic rod 45, and there is a pressure spring 47 behind the clamping telescopic rod 45 to support it. Therefore, when the clamping block 41 is closed, a stable fixing effect can be achieved. After the fixation is completed, the laser docking of the laser transmitter and receiver 6 between different clamping plates is opened. When the laser transmitter and receiver 6 cannot receive the signal of the other laser transmitter and receiver 6, it proves that the two columnar steel structures do not correspond well. If welding is performed at this time, it will cause dislocation, thereby affecting the welding effect. When the different laser transmitters and receivers 6 correspond, it proves that the two steel structures have basically corresponded, and the welding effect can be guaranteed when welding them.
