[0006] 2. The existing welding device cannot be actively flipped after welding one end face of the aluminum alloy frame. It needs to be disassembled and then flipped over for assembly and welding. The operation is cumbersome and affects the welding efficiency. In addition, the aluminum alloy frame after one end face welding is not firmly welded, which is easy to cause deformation and damage when flipping.

[0007] In view of the above problems, an innovative design was carried out based on the original aluminum alloy door and window frame welding device with automatic flip tooling. Summary of the invention

[0031] By adopting the above technical solution, through the cooperation of the inner ratchet and the pawl, the second gear can provide unidirectional rotation transmission for the second transmission rod. When the second rack moves forward and drives the second gear to rotate, the second gear drives the second transmission rod to rotate synchronously, and when the second rack moves backward, the rotation of the second gear does not drive the second transmission rod to rotate.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: the aluminum alloy door and window frame welding device with automatic flipping tooling can limit the activity trajectory of the welding module during the forward and backward movement of the welding mechanism by setting a limiting structure, so that the welding module is consistent with the trajectory of the area to be welded, and the operation is simple. In conjunction with the active flipping structure, it can actively flip over after one end face is flipped, thereby improving the convenience and efficiency of welding.

[0033] 1. By setting up a transmission mechanism, after the welding mechanism moves forward to complete the welding of the upper end surface of the aluminum alloy frame, the transmission mechanism is provided with power, and the transmission mechanism is used to provide rotational power for the clamping mechanism, and the aluminum alloy frame is flipped. After the flipping is completed, the welding mechanism moves backward to weld the other side of the aluminum alloy frame, thereby improving the welding efficiency;

[0034] 2. By providing a multi-directional clamping mechanism, multiple groups of aluminum alloy frames can be clamped and positioned synchronously, and the clamping mechanism can avoid blocking the corners of the aluminum alloy frame after clamping the aluminum alloy, thereby avoiding affecting the normal welding of the corners of the aluminum alloy frame.
