Detection structure of upper cover assembly

The utility model relates to the technical field of detection structures, in particular to a detection structure of an upper cover assembly, which comprises a detection plate and a product body, a plurality of positioning blocks are mounted at the bottom of the detection plate, through holes are formed in the bottoms of the positioning blocks, and positioning pins matched with the through holes are mounted in the product body. The detection plate is provided with a plurality of groups of detection assemblies and a plurality of correction holes, and the interior of the inner hole in the product body is connected with a limiting cylinder. According to the detection structure of the upper cover assembly, through the cooperation of the positioning block and the positioning pin, the product body can be corrected and limited at the same time, the detection error caused by the deviation of the detection assembly during the detection of the detection hole can be avoided, and under the action of the limiting cylinder
