Problems solved by technology

[0004] The invention patent with the authorized announcement number CN102506895B discloses a three-dimensional deformation accuracy inspection device for measuring instruments. The invention uses a ball screw and a matching ball screw nut The transmission mechanism of the threaded guide rail, but this transmission mechanism has the disadvantage of insufficient precision; one end of the ball screw is equipped with an adjustment handwheel, and a dial is arranged on the handwheel, which requires manual control of the displacement change and visual inspection. The reading is inconvenient to use and the accuracy is insufficient; the vertical displacement adjustment is difficult and the accuracy is low; the measurement accuracy of the three-dimensional deformation accuracy inspection device of the measuring instrument can only reach the centimeter or millimeter level, which is not suitable for deformation monitoring with higher requirements. Applicable, with lower overall reliability and accuracy
