High precision and high reliability electric cylinder positioning is a high-end technology product located in the electric cylinder. With the application background of the high-precision electric cylinder used in the QTT project of Xinjiang Observatory, it focuses on solving the structural design and positioning accuracy compensation control technology of the electric cylinder when there are large radial and axial forces simultaneously; Efficient, low wear, and long-life anti rotation technology for electric cylinders; The efficient and reliable mechanical self-locking technology can save 30% energy consumption compared to traditional mechanical self-locking. The compensation technology for the positioning accuracy of the electric cylinder at high and low temperatures of -40 ℃~60 ℃ has been solved. The high-precision and highly reliable electric cylinder has completed prototype production and entered the debugging stage. At the end of the year, it will enter the on-site multi cylinder linkage assessment stage.
