The invention discloses a hole-center coordinate positioning measurement apparatus, and relates to the technical field of measurement. The hole-center coordinate positioning measurement apparatus includes a three-jaw aperture micrometer, a space-limiting end cap, a magnetic carriage and an object target ball. One side of the space-limiting end cap is provided with a boss, and the opposite side of the space-limiting end cap is provided with a positioning pin. The surface of the outer circumference of the space-limiting end cap is provided with a first groove. The center of the space-limiting end cap is provided with a cylindrical through hole. The magnetic carriage is arranged to be a flange shaft. The center of the flange end surface is provided with a second groove. The space-limiting end cap is in fixed connection with the three-jaw aperture micrometer. The excircle dimension of the space-limiting end cap is larger than the excircle dimension of a housing. The excircle of a non-flange-end shaft of the magnetic carriage is matched with the cylindrical through hole. The object target ball is absorbed in a conical groove in the magnetic carriage. The advantages of the present invention are that the universality of the hole-center coordinate positioning measurement apparatus is raised; infinite variable diameters can be realized with regard to different diameter; the measurement cost is reduced; and the measurement precision is raised.
Description
technical field [0001] The invention relates to the technical field of measurement, in particular to a hole center coordinate positioning and measuring device. Background technique [0002] In aircraft development, there is a need for position detection of test benches, jigs, and on-board hole parts. A large number of joints containing through holes need to be positioned during the installation of test benches and jigs, and laser trackers are commonly used for positioning measurement. Under the measurement coordinate system, use the laser to track and irradiate the target ball located at both ends of the axis of the hole, measure and adjust the joint, and adjust the coordinates of the two ends of the upper axis to within the tolerance range to achieve the purpose of accurately positioning the joint. Since the diameter of the tail handle of the magnetic bracket (tracker accessory) supporting the reflective target ball of the tracker is not equal to the hole diameter of the j...
