Intelligent electric meter digital manufacturing platform based on intelligent manufacturing

A testing apparatus for testing a smart electric meter, the testing apparatus comprising:

• a workbench, a conveyor disposed on a top of the workbench, a frame fixedly disposed on a back of the workbench, an electric push rod fixedly disposed on an inner side of the frame, and a testing machine disposed on a telescopic shaft of the electric push rod;
• wherein the testing machine comprises:
• a box fixedly disposed on the telescopic shaft of the electric push rod, a testing component disposed in the box, and testing probes disposed on a bottom of the testing component;
• wherein the testing component comprises:
• an installation base fixedly disposed on an inner wall of a bottom of the box;
• first sliding grooves are defined on a front of the installation base and mirror-symmetrically arranged with a center point of the installation base, the first sliding grooves are designed to be inclined, and a first connecting piece and a second connecting piece are respectively slidably connected to insides of the first sliding grooves;
• bottoms of the first connecting piece and the second connecting piece are respectively fixedly connected to tops of the testing probes, auxiliary components are respectively disposed between the first sliding grooves and the first connecting piece and the second connecting piece, and the auxiliary components are configured to connect the first sliding grooves and the first connecting piece and the second connecting piece;
• wherein each auxiliary component comprises a first slider disposed in a corresponding one of the first sliding grooves and configured to slide along the corresponding one of the first sliding grooves;
• a front of the first slider is slidably connected to a connecting plate, and a front of the connecting plate is fixedly connected to a back of a corresponding one of the first connecting piece and the second connecting piece;
• and
• wherein the testing component further comprises:
• a servo motor fixedly disposed on a back of the installation base, a rotating shaft disposed on the servo motor and extended to the front of the installation base through a coupling, and a first pulley fixedly disposed on an end of the rotating shaft located on the front of the installation base;
• and
• a second pulley rotatably disposed on a lower end of the front of the installation base, and a pulling rope fixedly disposed on a top of the first connecting piece;
• wherein an end of the pulling rope facing away from the first connecting piece is fixedly connected to the bottom of the second connecting piece, the pulling rope is passed around the first pulley and the second pulley, a side wall of the pulling rope is fixedly connected to an inner side of the first pulley, the second pulley is configured to change a pulling direction of the pulling rope to the second connecting piece, so as to make the pulling rope pull one of the testing probes to move upwards through the first connecting piece and pull the other of the testing probes to move downwards through the second connecting piece when the servo motor drives the first pulley to rotate.
