[0002] Key nodes of transmission towers typically refer to critical connection points in the tower structure, such as the joints between beams and vertical members. The welding quality of these parts directly affects the overall stability and safety of the transmission tower. Automatic welding clamping devices for key nodes of transmission towers are specialized equipment used in the manufacturing process to automate the welding of key nodes. This device can improve welding efficiency, ensure welding quality, and reduce the labor intensity of workers. Existing automatic welding clamping devices for key nodes of transmission towers typically clamp the key nodes during welding to prevent movement that could lead to skewed welds. However, it is difficult to adjust the clamping position when clamping key node workpieces of different sizes, resulting in decreased welding quality and increased risk of welding defects. Utility Model Content
[0003] To overcome the limitations of existing automatic welding clamping devices for critical nodes of transmission towers, which typically clamp the critical nodes during welding to prevent movement that could lead to skewed welds, it is difficult to adjust the clamping position when clamping critical node workpieces of different sizes. This results in decreased welding quality and an increased risk of welding defects.

By setting a clamping component, clamping can be performed during welding to ensure the stability of the workpiece position during welding and prevent displacement or deformation during welding. By setting a lifting component, the optimal clamping points on both sides can be adjusted according to the different sizes of key node workpieces of transmission towers to prevent thermal deformation during welding caused by unsuitable clamping height. By setting a clamping component, the two sides of the key node workpiece of transmission tower can be stably clamped. By setting a control component, the operator can operate quickly and easily.
[0006] Preferably, the spacing adjustment component includes a welding platform, a first track plate, and a sliding frame. The welding platform is located above the base plate, and the first track plate is located on one side of the welding platform. Two sets of the first track plate are provided, and two sets of the sliding frame are located above the first track plate. In use, the two sets of sliding frames slide relative to each other on the two sets of first track plates, which can drive the pressure plate to move.
