An on-site calibration device for a hydraulic displacement servo system

Abstract

The invention relates to a field calibration device for a hydraulic displacement servo system and belongs to the technical field of geometrical measurement. The field calibration device comprises two ways of laser displacement sensors (5), sensor pose adjustment mechanisms (4), stand columns (2), laser reflecting plates (7) and magnetic targets (6) and a working table guiding mechanism, wherein the two stand columns are symmetrically disposed on a hydraulic cylinder base; the sensor pose adjustment mechanisms are mounted on the stand columns through magnetic force; the laser displacement sensors are fixedly mounted on the sensor pose adjustment mechanisms; the laser reflecting plates are disposed on a hydraulic displacement servo system working table; the magnetic targets are attracted to the laser reflecting plates through magnetic force; the working table guiding mechanism is fixedly mounted on the hydraulic cylinder base. Field calibration for the hydraulic displacement servo system can be performed; displacement tracing is achieved; the two ways of laser displacement sensors are symmetrically disposed, so that Abbe errors due to the fact the laser displacement sensors cannot be mounted in the center of a moving axis are effectively eliminated, and the calibration accuracy is improved.
