Automobile glass cover plate testing fixture

The utility model relates to the technical field of automobile parts, in particular to an automobile glass cover plate testing fixture. Comprising an operation table top, a positioning mechanism arranged on the operation table top and used for positioning a cover plate, two or more moving mechanisms arranged around the positioning mechanism, two or more profiling blocks connected with the movable ends of the moving mechanisms respectively and an error sensing assembly. The more than two profiling blocks can be spliced together to form a shape matched with the outer edge of the cover plate, and a detection end of the error sensing assembly is arranged on one side, close to the positioning mechanism, of each profiling block; and the moving mechanism is electrically connected with the first contact type sensor. According to the utility model, automatic detection of the molded surface of the cover plate is realized, errors caused by manual measurement are avoided, and the detection precision and efficiency are gr
