Problems solved by technology

Caliper measurement is to manually measure the specific size between two holes, and finally determine the measurement result through visual readings. At the same time, taking into account the influence of various external factors, this will definitely result in poor repeatability of the measured distance and inaccurate measurement data. And the final measurement results are saved through manual recording and uploading, which inevitably leads to mistakes and increases many uncontrollable factors
[0004] The inventor found that the three-coordinate measurement method is ideal in terms of the measurement results of the center distance between two holes, but the operation of the three-coordinate measurement method is complicated, time-consuming and laborious, and a little careless operation may cause measurement failure or even damage the measurement tool; and the caliper measurement and The three-coordinate measurement method is almost used in the measurement of the center distance of small holes in short distances, and it is difficult for both of them to measure the center distance of small holes in long distances.
