Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a welding clamp. Background Art

[0002] During the welding and splicing process of a metal cabinet, when welding and connecting two adjacent metal plates placed at a certain angle, a welding fixture is usually required to clamp the metal plates. A cabinet assembly welding fixture with publication number CN220127975U includes a mounting base plate, a clamping mechanism for fixing the cabinet plate by suction is installed on the periphery of the mounting base plate, and also includes a limiting mechanism for moving a limiting structure by rotation, and the limiting mechanism is installed on the upper end of the mounting base plate; through the above technical scheme, when the device clamps the panels around the cabinet, the motor is started, and the limiting shaft is slidably matched with the S-shaped sliding frame and the mounting base plate. After the motor drives the turntable to rotate, the limiting shaft will move with the shape of the S-shaped sliding frame, so that the spacing between the four limiting shafts changes. In this way, the device can be adjusted to match the size of the cabinet panel, so that the device can process cabinets of more sizes, and then the structure in the middle of the limiting shaft is slidably matched with the S-shaped sliding frame, so that the S-shaped sliding frame can be limited to avoid it from being separated from the mounting base plate; in this patent document, although the plate can be fixed and clamped, it can only fix adjacent metal plates at right angles, which is not suitable for fixing special-shaped cabinets, and the scope of use is limited.
