The utility model discloses an apparatus for testing the drifting of the pivot center of a flexible joint. The top of a vertical support bar of the apparatus is fixedly connected to one end of a horizontal support bar, a first displacement sensor and a second displacement sensor are arranged on the sidewall of the vertical support bar, and a third displacement sensor is arranged on the bottom of the horizontal support bar. The probes of the first displacement sensor and the second displacement sensor attach to the side surface of a swing rod, and the probe of the third displacement sensor attaches the top end face of the swing rod. The other end of a servo actuator is hinged to a connecting portion, a recess is arranged in a swing experiment table, and the top of the groove is used for installing a flexible joint. The bottom of the swing rod is fixed with a second rubber metal alternatively composite layer after penetrating a first rubber metal alternatively composite layer on the center of the flexible joint, and the signal output ends of the first displacement sensor, the second displacement sensor and the third displacement sensor communicates with a communication end of a computer. The apparatus is convenient and fast for testing, high in test precision and satisfies the requirements of product design precision.
