High-precision product measuring jig

The utility model relates to the technical field of positioning mechanisms, in particular to a high-precision product measuring jig, which comprises a jig for placing a product and a rotating assembly for driving the jig to rotate, the jig is fixed on the output end of the rotating assembly through a jig mounting plate, the jig is of an L-shaped structure, one end of the jig is provided with an X-direction positioning plate, and the other end of the jig is provided with a Y-direction positioning plate. A Y-direction positioning plate is arranged at the other end of the jig, a movable positioning plate of an L-shaped structure is arranged in the middle of the jig, and the movable positioning plate is fixed to the jig mounting plate through an elastic assembly in a position-adjustable mode. By the adoption of the structure, the movable positioning plate elastically clamps a product placed on the jig through the elastic assembly, the movable positioning plate is good in stress and has the effect of buffering for
