The utility model discloses a laser ruler for calibrating a coordinate measuring machine, including a laser interferometer, an interferometer, a reflector, a base, a guide and a measuring ball. The laser interferometer, the interferometer and the guide rail are fixed on the base. The reflector and the measuring ball are slidably arranged on the guide rail, and the mirrors and the mirrors are used. The measuring ball is synchronized on the guide rail. The laser interferometer is used to measure the moving distance of the mirror, and the measuring distance of the ball is measured by a calibrated coordinate measuring machine. The utility model uses a reflector and measuring ball to move together on the guide rail, and uses a laser interferometer to measure the moving distance of the mirror. At the same time, the measuring distance of the ball is measured by a calibrated coordinate measuring machine, and the distance value of the measuring distance of the coordinate measuring machine is compared with the measurement distance value of the laser interferometer. Coordinate measuring machines meet the accuracy requirements of calibration, so that the calibration of large calibrating coordinate measuring machines can be completed quickly and accurately.
