Description
Technical Field
The utility model relates to a steel ruler calibration detection area especially relates to a steel ruler calibration detection device.
Background
The ruler is a very common length measuring instrument used for measuring linearity and flatness by a light gap method, and can be used together with a measuring block for checking length size, and the measurement is completed by reading a numerical value on the ruler.
At present, the measurement units are compared by a standard device and a straight steel ruler, the measurement units are directly placed on a platform, and observation and comparison are carried out by artificial naked eyes, so that whether indication errors and the like of the straight steel ruler meet the standards or not is judged.
The prior art has the following problems:
1. the existing detection device is compared with a standard ruler, and the steel ruler is inconvenient to fix and flatten two ends of the steel ruler, so that calibration detection data are influenced;
2. the manual operation is very troublesome, and the examination time is long, is difficult to aim at the datum line, and eyes are tired easily, and slight error during the calibration simultaneously, the naked eye can not discern, can't accurate judgement error value.
