[0002] For the frame structure, before welding, the frame structure to be welded needs to be fixed by the frame fixing device, and then the fixed frame structure may be welded to prevent welding deformation from affecting the appearance size of the product. At the same time, the frame fixing device is used to support and fix the frame structure to a specific angle, which is also convenient for the staff to weld;

[0003] The existing frame structures have different thicknesses and widths during actual welding. Since the lengths, widths and thicknesses of the frames to be welded are inconsistent, if the frames of different lengths, widths and thicknesses cannot be fixed and supported, it will easily cause shaking during welding, thereby affecting the accuracy of welding. For this reason, we propose a welding frame fixing device to solve the above problem. Utility Model Content

[0006] As a preferred technical solution of the utility model, rotating rods are provided in both the front and rear ends of the placing platform for limited rotation, and both ends of the rotating rods are fixedly provided through the central axis of the worm.

[0007] As a preferred technical solution of the utility model, one end of the two rotating rods is connected to a mounting block for limited rotation, and the other ends of the two rotating rods are movably passed through the mounting block and connected to the power output end of the servo motor.

[0009] As a preferred technical solution of the utility model, the threads of the two worms at both ends of the rotating rod are opposite to each other.

[0010] As a preferred technical solution of the utility model, a support leg is fixedly connected to each of the four corners of the bottom wall of the placement table to support and fix the entire device.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:
