Through the coordinated use of structures such as the support plate 1, U-shaped frame 5, clamping plate 7, worm 11, threaded rod 19 and adjusting block 21, the spacing and clamping angle of the clamping mechanism can be adjusted according to the size and arc shape of the automobile roof frame, so that the device can clamp automobile roof frames of different sizes and different arcs, avoiding the use of welding tooling, which is easy to cause the clamping position to be squeezed and damaged by pits when clamping roof frames of different models and curved arcs, affecting the quality of the automobile roof frame, thereby improving the practicality of the welding tooling.

[0031] A rubber plate 13 is fixedly connected to the bottom of the inner wall of the U-shaped frame 5, and a rubber plate 2 14 is fixedly connected to the bottom of the clamping plate 7.
