The utility model provides a special turnover device for bracket welding, which comprises a turnover bracket, a fixing mould for fixing a bracket is rotatably supported and mounted at the top of a support upright post of the turnover bracket, and hand wheel devices for driving the fixing mould to turn over are symmetrically mounted on two sides of the fixing mould; a plurality of anti-deformationclamps used for clamping brackets are arranged on the periphery of the fixing mould. The turnover support comprises a bottom frame, supporting stand columns are vertically fixed to the tops of the twosides of the bottom frame, inclined supports are fixed between the side walls of the supporting stand columns and the bottom frame, and U-shaped grooves are formed in the tops of the supporting standcolumns. The turnover device is simple in turnover process and can basically replace a crane for cooperation; the safety coefficient is high; welding deformation and welding station conversion can bebetter controlled; the device is economical and reliable, and the processing period is shortened.
