A carbon
brush detection device of the present invention comprises a main body, a length detection
assembly, a processor and a
pressure detection assembly, the length detection
assembly comprises a fixed probe rod, a movable probe rod, a displacement sensor and a driving assembly, one end of the fixed probe rod is arranged on the main body, the other end of the fixed probe rod is provided with a top plate, and the movable probe rod is movably arranged on the main body. The displacement sensor is arranged on the fixed feeler lever to detect the moving distance of the movable feeler lever, and the driving assembly is connected with the movable feeler lever to drive the movable feeler lever to move; the processor is electrically connected with the displacement sensor; the
pressure detection assembly comprises a tension meter and a fixing band, the tension meter is slidably arranged on the main body, and the fixing band is arranged at the measuring end of the tension meter. According to the carbon
brush detection device, the pressed state of the carbon
brush in the actual state is accurately restored, deviation of detection data can be effectively avoided, the detection accuracy of the device is improved, meanwhile, in the detection process, multiple detection tools do not need to be used, and use is more convenient.
