Comprehensive calibration device

The invention provides a comprehensive calibration device, used for detecting and calibrating linear displacement and/or angular displacement of a sensor. The comprehensive calibration device comprises a base plate, two first supports, a ball screw, a linear motor, a second support, a mounting plate and a rotary motor; the two first supports are arranged at the two ends of the base plate in the length direction; the ball screw comprises a screw and a screw nut matched with the screw nut by virtue of a screw thread, the screw is parallel to the base plate, and the two ends of the screw are respectively fixed on the two first supports; the linear motor is fixedly arranged on the first supports and used for driving the ball screw to rotate, so that the screw nut moves back and forth on the screw; the bottom of the second support is fixed on the base plate, and the side surface of one first support is fixed on the second support; the mounting plate is arranged at the top of the second support and used for bearing
