Vehicle body trial-manufacturing platform

The invention provides a vehicle body trial-manufacturing platform which comprises four transverse moving mechanisms, two longitudinal moving mechanisms, lifting equipment and a bottom layer frame, the bottom layer frame is a rectangular frame extending in the longitudinal direction, and the two longitudinal moving mechanisms are oppositely arranged on the left side and the right side of the top of the bottom layer frame; the two longitudinal moving mechanisms can move on the bottom layer frame in the longitudinal direction. The two transverse moving mechanisms are oppositely arranged on the top of each longitudinal moving mechanism, and the two transverse moving mechanisms can move on the longitudinal moving mechanisms in the transverse direction; each transverse moving mechanism is provided with a positioning mechanism used for being matched with a positioning hole in a vehicle body. And the lifting equipment is used for supporting the bottom-layer frame, and the lifting equipment is arranged below the bott
