Anode tank and anode plate installation precision test method and tool measuring shaft

The invention relates to an anode tank and anode plate installation precision test method and a tool measuring shaft, the tool measuring shaft comprises a tool shaft, two sides of the tool shaft are respectively provided with a snap ring adjusting wheel, each snap ring adjusting wheel is fixed on the axial surface of the tool shaft through a fastening device, and the tail end of the tool shaft is connected with a connector; the tool measuring shaft is used for replacing a cathode roller for installation, so that the snap ring adjusting wheel is matched with the bearing seat; then a connector is used for connecting the motor and the tool measuring shaft, the motor is started and drives the tool measuring shaft to rotate, and the positioning precision of the bearing seat is automatically adjusted in the rotating process; measuring the radial distance between the tool shaft and the arc in the anode groove by using a measuring tool, and reading; then statistical analysis is carried out on a measurement result of
