There are corresponding positioning sockets 22, and the matching ends of the positioning sockets 22 and the alignment holes 5 are plugged with fastening pins. When the fixed clamping tooling is used as a tooling table for the high-speed rail energy absorbing body, the clamp assembly 2 can be pushed in turn according to the size of the energy absorbing body to slide symmetrically along the groove direction of the track slide groove 3, and the positions of the two adjacent groups of clamp assemblies 2 can be calibrated to match the energy absorbing body. After the calibration, the matching fastening pins can be inserted into the matching ends of the positioning sockets 22 and the alignment holes 5.
