Device and method for detecting positioning precision of tail end of surgical robot

The invention relates to the technical field of medical instruments, and discloses a device and method for detecting the positioning precision of the tail end of a surgical robot. Wherein the tail end of the surgical robot is fixedly mounted at one end of the tail end positioner, and the other end of the tail end positioner is fixedly mounted on the detection table; the detection table comprises a base, a detection groove, a plurality of target holes formed in the bottom surface of the detection groove, a plurality of detection probes, a plurality of detection electrode plates and an indicator; one end of the indicator is electrically connected with the base and the other end is electrically connected with the detection probe; after a detection probe penetrates through a positioning hole in the tail end of the surgical robot, the positioning accuracy of the positioning hole in the x-axis direction, the y-axis direction and the z-axis direction is judged according to the contact condition of the bottom end of
