The front crossbeam is located behind the front bumper of the vehicle head, the rear crossbeam is located at the rear of the vehicle, and the middle crossbeam is located in the middle of the vehicle. These crossbeams are connected to the wheels through components such as longitudinal beams, suspension devices, front axles and rear axles, jointly constituting a stable vehicle body foundation;

[0003] Upon inquiry, the publication number is: CN220008885U, which discloses an automatic welding correction device. In this technology, "an automatic welding correction device includes a working platform and support legs.
