Mechanical hand for automatically overturning motor stand

The invention discloses a mechanical hand for automatically overturning a motor stand. A bracket is arranged across a motor stand conveying rail, wherein a translation mechanism and a lifting mechanism are arranged on the upper part of the bracket; the lifting mechanism comprises a lifting upright post; a clamping mechanism and an overturning control mechanism for controlling the 90-degree overturning of the clamping mechanism are arranged at the lower end of the lifting upright post; when the clamping mechanism extends into the motor stand, and the motor stand is fixedly clamped by the clamping mechanism, the motor stand is uplifted by the lifting mechanism to a preset position, then is overturned by 90 degrees by the overturning control mechanism, is moved to a preset position by the translation mechanism along the motor stand conveying rail, is lowered and placed on the motor stand conveying rail by the lifting mechanism, and is released by the clamping mechanism, the clamping mechanism withdraws, and is driven to ascend to a preset position; by such a cycle, the motor stand is automatically overturned for operation, so that the labor cost is lowered, and the production efficiency is improved.
