Compared with the prior art, the utility model has the following beneficial effects: the flip self-locking welding tooling,

(1) The utility model can effectively solve the problem that most existing welding tools need to manually adjust the welding position of the workpiece through the coordinated use of the motor, the first screw and the second screw. That is, after one side of the workpiece is welded, the worker needs to manually move the limit assembly to flip it and then limit it again, which is not convenient to operate and affects the processing efficiency. The motor drives the active shaft to rotate. While the active shaft rotates, it will synchronously drive the driven shaft, the first screw and the second screw to rotate through the belt transmission structure and the bevel gear transmission structure. When the driven shaft rotates, it will drive the flip frame and the workpiece inside it to flip, so as to achieve the purpose of automatic flipping. On the other hand, the slide seat on the first screw and the second screw will push the locking rod to move in the direction until the locking rod on one side self-locks the flip frame, thereby preventing it from accidentally rotating during the welding process, thereby ensuring the normal progress of the welding work.

(2) The utility model can effectively solve the problem that the existing welding tooling usually has a large clamping force to ensure the stability of clamping, which easily causes wear on the workpiece surface through the coordinated use of the limit component, the electric telescopic rod and the movable plate. The electric telescopic rod pushes the movable plate and the limit component inside it to move inward, so that workpieces of different sizes can be limited. At the same time, the air bag in the limit component can prevent the device from directly contacting the workpiece, thereby avoiding wear on the workpiece during the clamping process.
