Abstract: An intelligent electric meter digital manufacturing platform based on intelligent manufacturing includes: an electric push rod fixedly disposed in a frame and a testing machine disposed on the electric push rod. The testing machine includes a box fixedly disposed on a telescopic shaft of the electric push rod and a testing component disposed in the box. A first pulley drives two ends of a pulling rope to move from a middle end of a side wall of the pulling rope through driving of a servo motor. This makes an end of the pulling rope pull a testing probe to move upwards, the other end of the pulling rope pull the other testing probe to move downwards, allowing it move to a bottom of the box. This design avoids affecting testing efficiency due to the need to replace or maintain the testing probes, facilitating subsequent testing of an intelligent electric meter.
