A highly comprehensive inspection tool

technical field

The invention relates to measuring equipment, in particular to a part height checking tool.

Background technique

At present, most of the part height detection devices in industrial applications are only suitable for the height detection of a single plane of the part. When it is necessary to detect the height of multiple different planes of the part at the same time, it is necessary to locate them one by one and detect the height of each plane separately. This way is too slow. One step further, the parts shown in Figure 5 and Figure 6 have a central hole in the center, and the height dimensions of the multiple lower side profiles of the parts are all assembly dimensions, and these height dimensions are all based on the reference plane shown in Figure 5. Datum, when it is necessary to detect the different underside profile heights of this type of part, it becomes more and more difficult.

First of all, there are many problems in the measurement of the lower side profile of the part. The existing height gauge cannot be used for the detection of the finished product, and the vernier caliper can only be used for manual measurement. There is a large error in the accuracy. For parts with flanges below, the height detection of the lower profile is affected by the flanges below, which makes manual measurement more difficult. Sometimes segmental measurement is required to determine the size of the target segment. It is so easy A large error is generated, and as a finished product inspection measurement, the traditional height measurement needs to read the measurement section, which increases the workload of the inspection personnel and slows down the production efficiency. Secondly, manually measuring the heights of different underside profiles of a part one by one will increase the error of a part when the original measurement error is large, affecting its use, and its detection speed is slow Seriously slow down production efficiency.
