The invention relates to the technical field of vehicle body production or repair equipment, in particular to a vehicle body hydraulic turnover machine. The vehicle body hydraulic turnover machine comprises a rack, a main beam, a turnover clamping device, an electric control cabinet and a hydraulic station, wherein the main beam is of a welded box beam structure; the rack is of a door type box structure; a supporting lifting platform is arranged in the box body and moves up and down along guide rails on the two sides of the box body through a lifting oil cylinder; the supporting lifting platform is provided with a hydraulic swing rotating mechanism; the lifting oil cylinder and a swing oil cylinder are both provided with a synchronous valve and double locks; the turnover clamping device is a lead screw clamping device with self-locking capacity; clamping interlock control devices are arranged on the two sides of the lead screw clamping devices. When hydraulic pressure is adopted for transmission by the improved vehicle body hydraulic turnover machine, synchronous coordination is performed by using a hydraulic control system to reduce the error probably produced during operation between two groups of transmission mechanisms, so the relatively balanced, stable, safe and reliable operation of equipment lifting and turnover action is realized.
