Technical Field

The utility model relates to a station difference in height and flatness detection technical field specifically are a station difference in height and flatness check out test set.

Background

In the prior art, in order to detect the height difference and the flatness of the stations, a method is generally adopted in which a dial indicator is used to perform manual meter-reading counting on each station based on a mobile system outside or above a machine to be detected. In the implementation process of the method, firstly, the magnetic suction dial indicator is adsorbed to a reference surface by taking a mobile system outside or above a machine table as a reference, and then the dial indicator is manually calibrated; after zero calibration is completed, firstly, a single station is subjected to meter making, the station is moved along the edge of the station, and the maximum jumping value in the process is manually recorded; then, jacking up the dial indicator probe, rotating the turntable of the machine table to the next station, and repeating the steps of zero calibration and meter reading; and finishing the meter making at each station. And finally, comparing the recorded maximum run-out data to obtain the maximum flatness deviation among the stations of the machine.

2. The prior art can not accurately compare the height difference and the flatness deviation among stations. Because zero calibration is needed after each movement, the reading of the mechanical dial indicator is difficult, and the height difference cannot be compared with the height difference of the previous station (the height difference can be read by using the electronic dial indicator); because the flatness of each station is measured by taking a reference surface as a standard, the difference of the flatness between stations is not enough to be described.
