SupplyHow does the diameter gauge in Chenzhou achieve high-precision measurement under extreme working conditions?
Achieving high-precision measurement under extreme working conditions requires the integration of multiple cutting-edge technologies. The following are the key solutions and implementation details:
Temperature adaptive optical path
By using a quartz glass lens group (with a thermal expansion coefficient of 0.5×10⁻⁶/℃) in combination with a real-time welength compensation algorithm, the laser welength drift caused by a temperature difference of -40℃ to 150℃ can be eliminated (with a compensation accuracy of 0.1μm for every 0.1℃ temperature difference). Case: In the measurement of a certain aero-engine blade, this technology reduced the thermal deformation error from ±15μm to ±1.2μm.
Multispectral redundancy measurement
Simultaneously emit 650nm red light and 405nm blue-violet laser, and eliminate medium interference (such as oil mist and dust) through dual-welength differential. Experiments show that in the dusty environment of the steel rolling production line, the measurement stability has increased by 83%.
Rotary scanning
The rotary probe driven by the conductive slip ring (with a rotational speed of 30rpm) can obtain the full cross-sectional data of the bar, and the roundness measurement accuracy is ±0.005mm (in compliance with ISO4292:19andard).
Adjustable pitch dual probes
Thread inspection of oil drill pipes: Under oil-contaminated conditions, the adjustable pitch dual measuring heads of Lanpeng Measurement and Control are adopted to achieve a pitch error of ±0.003mm (API Spec 7-2 requires ≤0.013mm).
