Abstract
A large rotary equipment coaxiality measurement device and method based on digital twinning, relate to the field of coaxiality measurement. The device includes a standard entity coaxiality measurement device, a collection device and a standard. The entity coaxiality measurement device includes a horizontal guide rail, a main vertical guide rail, a secondary vertical guide rail, a sensor, a counterweight, a steel wire rope, a fixed pulley, and an air floating module. The main and secondary vertical guide rails are fixed with the fixed pulley at the top, and the counterweight and the air floating module are connected with the secondary vertical guide rail and the main vertical guide rail slider respectively. One end of the steel wire rope is connected with the counterweight and the other end is connected with the air floating module. One end of the air floating module is fixed with the horizontal guide rail and the other end is fixed with the sensor, which is used to measure the coaxiality of the standard. The collection device includes AR glasses and a computer. The AR glasses are used to obtain information, and the computer processes and analyzes the information to obtain a virtual measurement device and dynamically controls the standard entity coaxiality measurement device. It is used in the field of ultra-precision measurement.
