Problems solved by technology

[0003] However, for feeler gauge detection, the staff needs to use a plane ruler when working. The larger the workpiece to be measured, the larger the plane ruler required. In addition, it is made of metal and has a high quality. It requires two to three people to work together, and the work efficiency is very low; For three-coordinate detection, special equipment is required, and the measurement accuracy is high, but it is a single-piece detection, which is slow and expensive; for laser plane interferometer measurement, the precision is high, only suitable for small-scale measurement, and the operation is complicated
The existing methods, for workpieces of different thicknesses, are not easy to adjust and adapt the height of the same measuring device for detection, and cannot take into account the difficulty and timeliness of measurement

Abstract

The invention discloses a flatness out-of-tolerance continuous measurement device and a measurement method thereof. The measurement device comprises a base platform, the device further comprises a guide travel mechanism arranged on a base platform, a height adjusting mechanism arranged on the guide travel mechanism and used for adjusting the height of a mounting rack, and a detection mechanism arranged on the mounting rack and used for performing flatness testing by contacting and extruding on a workpiece surface of the base platform. The precision of the measurement device is more precise than a feeler gauge, and lower than the three-coordinate detection and laser plane interferometer measurement, the operation is convenient, the measurement can be continuously performed, and the flatnessmeasurement difficulty and time of the measurement plate parts can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of measuring devices, and in particular relates to a flatness out-of-tolerance continuous measuring device and a measuring method thereof. Background technique [0002] At present, the flatness measurement of large parts mainly includes feeler gauge detection, three-coordinate detection, laser plane interferometer measurement, etc. The feeler gauge detection relies on the plane ruler as the reference, and the feeler gauge is used for manual measurement; the three-coordinate detection, the indicator moves on the sample to be tested, and the data of each measurement point relative to the measurement reference is measured according to the selected distribution point, and then passed through the data The flatness error is evaluated by processing; the laser plane interferometer is used to measure the ideal plane with the working surface of the optical flat crystal, and the flatness error value of the measured sur...
