The utility model discloses an utensil is examined to profile and hole site, including bottom plate, benchmark seat, pressing mechanism, benchmark post, locating pin, gapgauge and logical no -go gage, the benchmark seat has benchmark appearance and the basic hole that corresponds with the work piece, the benchmark seat is fixed in the bottom plate, the benchmark post is fixed in stretch out the bottom surface of benchmark seat the bottom surface of benchmark seat, the height that stretches out is in between the thickness value of two sense terminals of gapgauge, the locating pin set up in the bottom surface of benchmark seat just is upwards stretches out with the location the work piece, pressing mechanism will the work piece support press in the surface of benchmark post, the gapgauge is used for detecting the profile of work piece arrives clearance between the wall of benchmark appearance, lead to the no -go gage with the basic hole cooperation is used for detecting the size of the hole site of work piece. The utility model has the advantages of simple structure, it is convenient to detect, and it is high to detect the precision.
