Technical field

The invention belongs to be machined field of measuring technique more particularly to a kind of step depth measurement tools.

Background technique

Higher and higher with user demand, the previous not high aspect of some pairs of measurement requests, which also started to improve, to be required, example The measurement of the depth dimensions of such as step is not originally very high for the measurement request in terms of these, it is only necessary to using such as vernier The typical measuring arrangements of slide calliper rule one kind, if vernier caliper can measure depth of the step relative to datum level using its depthometer, But since vernier caliper is there are significant limitation, reading data is affected by human factors larger, therefore its precision often reaches Less than requiring, and it may also be subjected to the influence of structure on workpiece, measurement is quite inconvenient and efficiency is lower, is not suitable in high volume Detection, and existing some measuring devices can reach requirement, as three-dimensional coordinates measurement can be measured accurately, and have very high Precision, but its testing cost is high, is not suitable for mass detection.In order to improve the precision and efficiency of detection, while again can The structure for simplifying measuring device, reduces cost, the present invention a kind of step depth measurement tools are provided with overcome the problems, such as presently, there are, Keep measurement more efficient, easy to operate, as a result accurately, the scope of application is wider, there is certain market promotion prospect.
