technical field

The utility model belongs to the field of auto parts measurement, in particular to a device measuring device for measuring the positions of two points in three-dimensional space. the

Background technique

In the process of automobile production and inspection, it is necessary to measure and check the data of each part of the car body. If the data deviates, it is a substandard product. Especially for products with curved contours such as car doors, the actual data is difficult to measure because the reference point is not easy to determine. In the prior art, to measure the height difference between two points, you can only use a tape measure or other tools to roughly measure the height between the two points, and then calculate the height difference between the two points. However, the error of measuring with a tape measure itself is huge It is very large, and the benchmarks used to measure the two points of the tape measure are inconsistent, resulting in large errors in the measurement data, and it is impossible to accurately judge whether the product quality is qualified. the
