The invention provides an xyz three-axis linkage crane. The crane comprises a frame and an xy platform; a first worm, a second worm and a third worm are arranged on the frame; the first worm, the second worm and the third worm are all driven by a motor, the worms are connected with a worm gear in a matched mode, and the worms rotate to drive the xy platform to move upwards; and mecanum wheels are further arranged at the four corners of the bottom end of the frame and used for providing driving for the three-axis linkage crane. According to the xyz three-axis linkage crane provided by the invention, the accuracy of the crane passing through obstacles is improved by utilizing the accurate control characteristic of a stepping motor, and the crane can be lifted to any position to stop to realize a self-locking function through the control of the worm and gear motor with a stopping function, namely a mechanical self-locking function; and an angle sensor is additionally arranged, PID closed-loop feedback adjustment is achieved, synchronous lifting is ensured, the crane can move in the x direction, the y direction and the z direction, the lifting efficiency is improved, and the lifting precision is improved.
