The invention discloses a calibrating device for an eddy sensor. The calibrating device comprises a micrometer, wherein the micrometer is fixed on a rack base through a micrometer bracket; a measuring flat-end is connected with the micrometer; a sensor bracket is fixed on the rack base; a sensor positioning block is fixed on the sensor bracket; the sensor bracket and the axis of the micrometer bracket are on the same straight line; a V-shaped groove structure is arranged on the sensor bracket; the eddy sensor is clamped in the V-shaped groove structure and locked through the sensor positioning block and a positioning screw; the rack base is made from high-carbon steel and marble materials; the reaction of the eddy sensor to displacement variation can be calibrated by fine adjustment to precision of the micrometer; calibration is realized by data comparison; and by changing the distance between the eddy sensor end surface and the measuring flat-end, the linearity and the sensitivity of the eddy sensor can be measured. Therefore, the calibrating device has the characteristics of high resolution, easy operation and adjustable linear range, and has the advantages of stable and reliable detection result and simple operation.
