Device for measuring service life and stability of balance cylinder of industrial robot

The invention discloses an industrial robot balance cylinder service life and stability measuring device which comprises a rack, a camera is fixedly installed on one side of the rack through a support, a displayer is fixedly installed on the surface of the rack through a support, a servo motor is fixedly installed on the surface of the rack through a support, and the servo motor is fixedly connected with the camera through a support. The outer side of the output end of the servo motor is sleeved with a torque rotating speed sensor, the output end of the servo motor is fixedly connected with the input end of a speed reducer, and a temperature sensor is embedded in a side face support of the speed reducer. By adopting the high-precision speed reducer for the industrial robot, the operation working condition can be effectively restored, and meanwhile any balance cylinder position can be accurately reached; the fixed seat A and the fixed seat B are arranged, so that balance cylinders with different strokes can be
