Turnover device

The invention relates to the technical field of machining equipment, in particular to a turnover device. Comprising a base, a fixed support, a movable support, a fixed supporting groove, a movable supporting groove formed in the bottom of the movable support, a telescopic supporting mechanism arranged on the inner side wall of the top of the fixed support or/and the movable support, an overturning clamp used for clamping a workpiece and two rotating parts rotationally connected to the two sides of the overturning clamp correspondingly. The two rotating parts are detachably connected with the fixed supporting groove and the movable supporting groove correspondingly, and the telescopic end of the telescopic supporting mechanism stretches to abut against the bottom of the overturning clamp. The turnover fixture is simple in structure and low in cost, the turnover fixture clamping a workpiece can be conveniently turned over, the front face and the back face of the workpiece can be conveniently machined by externa
