Automatic gradienter detection device

The utility model relates to an automatic gradienter detection device. The jig comprises a jig base, a bubble level, an image shooting device and an operation server, wherein the jig base is providedwith a measuring surface, and a first setting surface and a second setting surface which are parallel to the measuring surface; the bubble level is arranged on the first setting surface; the image shooting device is arranged on the second setting surface and is used for shooting the bubble level to obtain a position image of a bubble, and the operation server is connected with the image shooting device and is used for identifying the position of the bubble in an image analysis mode according to the position image and converting the inclination angle of the measuring surface; therefore, the measuring surface is placed on a surface to be measured, the inclination angle of the measuring surface can be automatically measured, the error influence of naked eye identification can be reduced, thedetection precision is imp
