Robot hand-eye calibration device

The utility model provides a robot hand-eye calibration device, which relates to the field of robots and comprises a base and a calibration plate clamp. The base is provided with an installation part used for being installed on a robot arm. The calibration plate clamp is connected to the base and comprises a fixed seat, a first clamping block, a second clamping block and a clamping block adjusting mechanism; the fixing seat is connected to the base, the first clamping block and the second clamping block are connected to the fixing seat through the clamping block adjusting mechanism, and the clamping block adjusting mechanism can adjust the clamping distance between the first clamping block and the second clamping block so as to clamp or loosen the calibration plate. The utility model at least solves the problems that in the prior art, a robot hand-eye calibration plate and a calibration tool are of an integral non-detachable structure, the size of the hand-eye calibration plate is fixed and cannot be replaced
