Problems solved by technology
[0006] In order to solve the problem that the existing press machine tool does not have the detection function of the deformation amount, the conventional detection of the distortion of the side beam and the cold adjustment of the press machine require frequent switching between the scribing machine and the press machine tool. The repair method is time-consuming, laborious, and inefficient, and because of the high rigidity of the side beam, the pressure during the above-mentioned cold repair is not easy to control, and often leads to problems such as serious indentation of the side beam or cracking of the weld seam, resulting in the scrapping of the weldment and other economical problems. For the technical problem of loss, the present invention provides a bogie side beam torsion detection and repairing device and its repairing method
