The invention provides an x-y-z three-axis linkage crane. The x-y-z three-axis linkage crane comprises a frame and an x-y platform; the frame is provided with a first worm, a second worm and a third worm; the first worm, the second worm and the third worm are all driven by a motor, the worms are connected with worm wheels in a matched mode, and the worm rotation is used for driving the x-y platform to move upward; and mecanum wheels for driving the three-axis linkage crane are arranged at four corners of the bottom end of the frame. The x-y-z three-axis linkage crane improves the accuracy of the crane in passing through obstacles through the accurate control characteristic of a stepping motor, and the crane can lift to any position to stop to realize the self-locking function through the control of the worm wheels, the worms and the motor with stop meaning mechanical self-locking; and PID closed-loop feedback adjustment is realized by adding an angle sensor, and the synchronous liftingis ensured. The crane can realize x-y-z moving in three directions, the lifting efficiency is improved, and the crane accuracy is increased.
