Detection device for detecting position accuracy of spatial hole

The utility model provides a detection device for detecting the position accuracy of a spatial hole, which comprises a body, a plurality of guide sleeves and a plurality of measurement rods. The body is provided with a binding surface bonded to the extending end of the spatial hole, and a plurality of mounting through holes configured to pass through the binding surface. The guide sleeves are in interference fit with the mounting through holes. The measurement rods are in sliding fit with reference holes in the guide sleeves. The included angles of the reference holes relative to the binding surface are equal to the included angle of the spatial hole relative to the extending end. By means of the device, the spatial hole can be quickly and accurately detected. The device is simple and compact in structure.
