The invention relates to a device and a method for measuring repeated positioning accuracy of industrial robot spatial poses. The device comprises an execution block, a laser distance measuring sensor, a gyroscope, a special ball-shaped light receiving screen, an extensometer support, levelling instruments, adjusting screws, a computer and a wireless communication module. The computer controls a mechanical arm of an industrial robot to move, so that displacement of the mechanical arm in x, y and z axes is controlled. The method comprises steps as follows: acquired data are transmitted by the laser distance measuring sensor and the gyroscope to the computer through the wireless communication module and are processed, a series of coordinate values are generated, the data are calculated, error values are obtained, and the repeated positioning accuracy is calculated finally. The device and the method are more convenient during application and measurement, the data can be rapidly acquired, and the device is simple
