The invention belongs to the technical field of overturning devices, and particularly relates to an overturning device for mechanical part production. Aiming at solving the technical problem that mechanical parts are prone to falling in the overturning process, and consequently, large potential safety hazards exist, the following scheme is currently put forward, specifically, the overturning device comprises an overturning base, the two sides of the upper end of the overturning base are connected with a first side support and a second side support correspondingly, a lifting device is arrangedbetween the first side support and the second side support, clamping pushing plates are arranged on the sides, close to each other, of the first side support and the second side support correspondingly, the ends, away from each other, of the first side support and the second side support are connected with extrusion driving devices correspondingly, the power output ends of the extrusion driving devices penetrate through the first side support and the second side support and are fixedly connected with the clamping pushing plates, the clamping pushing plates are connected with rotating devices,and each rotating device comprises a rotating driving device and a pair of clamping rotating discs. The clamping degree of the mechanical parts can be guaranteed, later stable overturning of the mechanical parts is guaranteed, and the safety factor is increased.
