The invention relates to a worm gear and worm engagement detection device which comprises a worm gear positioning cylinder and a worm clamping mechanism, the worm gear positioning cylinder is fixedlyconnected to a linear sliding table, and the linear sliding table and the worm clamping mechanism are both fixedly installed on a workbench; a worm gear is arranged on the worm gear positioning cylinder, and a worm is arranged on the worm clamping mechanism; the device also includes an angle encoder which is used for detecting the meshing transmission ratio of the worm wheel and the worm, a seconddisplacement sensor which is used for detecting the radial run-out of the worm wheel, and a first displacement sensor which is used for detecting the meshing center of the worm wheel and the worm. According to the worm and gear engagement detection device, the angle encoder, the second displacement sensor and the first displacement sensor are used in cooperation, the meshing condition of the wormwheel and the worm is dete
