Description

Technical Field

[0001] This utility model belongs to the field of steel welding technology, and in particular relates to a welding equipment for building steel. Background Technology

[0002] In steel plate construction, welding between steel plates is a common connection method, playing a crucial role in ensuring the integrity and stability of the steel plates. It is widely used in large-scale engineering projects such as bridges and high-rise buildings. Using welding to connect steel plates effectively enhances the overall structural integrity, simplifies the construction structure, and reduces construction costs, thus it is widely used in current technology. However, current technology largely relies on manual labor for steel plate welding. Manual welding requires welders to maintain focus and stable hand gestures for extended periods, especially in large or complex steel plate projects, or when welding two steel plates at a specific angle, posing a significant challenge to the welder's physical strength and endurance. Furthermore, manually fixed steel plates are prone to displacement or shaking during welding, thus affecting welding quality and efficiency. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a welding equipment for building steel.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A welding device for building steel includes a mounting frame, a first processing platform, and a second processing platform;

[0006] Both the first and second processing platforms are located on top of the mounting frame;

[0007] The second processing platform is rotatably mounted on the side of the first processing platform;

[0008] A robotic arm is provided on one side of the first processing platform, and a welding gun is provided on the robotic arm;

[0009] The first processing platform is equipped with a first clamping assembly;

[0010] The second processing platform is equipped with a second clamping assembly;

[0011] The second clamping assembly is equipped with a transmission assembly for conveying the steel plate;

[0012] The mounting frame is equipped with a pushing component, which is connected to the second processing platform and is used to drive the second processing platform to rotate.

[0013] The above technical solution involves placing two steel plates to be welded onto a first processing platform and a second processing platform, respectively. The first clamping component and the second clamping component clamp the two steel plates, respectively. The pushing component drives the second processing platform to rotate relative to the first processing platform, thereby causing the steel plate on the second processing platform to rotate to the corresponding angle. The transmission component drives the steel plate to move so that the end is clamped to the welding position of the other steel plate. The robotic arm drives the welding gun to weld the connection position of the two steel plates, thereby realizing welding of steel plates at different connection angles without manual support and improving welding accuracy.

[0014] Furthermore, the first clamping assembly includes a first clamping plate, a first groove is provided on the first processing platform, a first bidirectional screw is provided in the first groove, the two ends of the first bidirectional screw have opposite thread directions, the lower ends of the two first clamping plates are slidably disposed in the first groove, and the first clamping plates are threadedly connected to the two ends of the first bidirectional screw, one end of the first bidirectional screw extends out of the first groove and is connected to a first motor, the first motor is disposed on the side of the first platform.

[0015] Through the above technical solution, the first motor drives the first bidirectional screw to rotate, thereby causing the two first clamping plates to move closer to each other and clamp the steel on the first processing platform.

[0016] Furthermore, the second clamping assembly includes a second clamping plate; the second processing platform is provided with a plurality of second grooves, and a second bidirectional screw is rotatably disposed in the second grooves, the two ends of the second bidirectional screw having opposite thread directions;

[0017] The lower ends of the two second clamping plates are slidably disposed in the second groove, and the two ends of the second clamping plates are threadedly connected to the two ends of the second bidirectional screw.

[0018] One end of the second bidirectional screw extends out of the second groove and is connected to a second rotating wheel; adjacent second rotating wheels are rotatably connected by a second transmission belt.

[0019] The second processing platform is equipped with a second motor on its side, and the output end of the second motor is connected to one of the second rotating wheels;

[0020] The transmission assembly is mounted on the second clamping plate.

[0021] Through the above technical solution, the second motor drives one of the second rotating wheels to rotate, and through the second transmission belt connected in sequence, drives the other second rotating wheels to rotate, thereby realizing the rotation of all the second bidirectional screws, which drives the two second clamping plates to move relative to each other to clamp the steel plate.

[0022] Furthermore, the transmission assembly includes a rotating column;

[0023] A third groove is provided on one side of the two second clamping plates opposite each other. Multiple rotating columns are rotatably arranged in the third groove. One end of each rotating column extends out of the third groove and is connected to a first rotating wheel. Adjacent first rotating wheels are connected by a first transmission belt.

[0024] The second clamping plate is equipped with a third motor at its top, and the output end of the third motor is connected to one of the first rotating wheels.

[0025] Furthermore, the side of the rotating column is provided with an anti-slip pad.

[0026] With the above technical solution, when the second processing platform rotates to a suitable angle, the third motor rotates and drives the first rotating wheel to rotate, thereby driving the rotating column to rotate through the connection of the first transmission belt, and transmitting the steel on the second processing platform downward to the welding point with the first processing platform. The frictional resistance of the anti-slip pad can improve the stability of steel clamping and conveying.

[0027] Furthermore, the pushing component includes a cylinder, the mounting bracket is provided with a mounting groove, the mounting groove is provided with a mounting seat, and the cylinder is rotatably mounted on the mounting seat;

[0028] The second processing platform is provided with connectors on both sides, and a rotating sleeve is fitted on the connector. A connecting rod is provided on the side of the rotating sleeve, and the connecting rod is connected to the output end of the cylinder.

[0029] Through the above technical solution, the cylinder extends and drives the connecting rod to move, thereby causing the rotating sleeve to rotate on the connecting part due to the displacement, and pushing the second processing platform to rotate.

[0030] Furthermore, the first processing platform is provided with a turntable, the turntable is provided with a scale, and the turntable is provided on one side of the second processing platform;

[0031] The second processing platform is equipped with a pointer, which is located on one side of the turntable.

[0032] The above technical solution allows for a better view of the rotation angle of the second processing platform.

[0033] This utility model has the following beneficial effects:

[0034] 1. Place two steel plates to be welded onto the first processing platform and the second processing platform respectively. The first clamping component and the second clamping component clamp the two steel plates respectively. The pushing component drives the second processing platform to rotate relative to the first processing platform, thereby causing the steel plate on the second processing platform to rotate to the corresponding angle. The transmission component drives the steel plate to move so that the end is clamped to the welding position with the other steel plate. The robotic arm drives the welding gun to weld the connection position of the two steel plates, thereby realizing the welding of steel plates at different connection angles without manual support and improving welding accuracy.

[0035] 2. When the second processing platform rotates to a suitable angle, the third motor rotates and drives the first rotating wheel to rotate, which in turn drives the rotating column to rotate through the connection of the first transmission belt. The steel on the second processing platform is then transmitted downwards to the welding point of the first processing platform. The frictional resistance of the anti-slip pad can improve the stability of steel clamping and conveying. Attached Figure Description
