Detection tool for conic hole diameter detection

Abstract

The invention discloses a detection tool for conic hole diameter detection. The detection tool comprises a cushion sleeve, a sleeve and a measuring rod, wherein the measuring rod is sleeved in the sleeve, the surface of the cushion sleeve is provided with a conical groove in the axial direction, the bottom surface of the conical groove is provided with a through hole, the bottom surface of the sleeve is provided with a circular groove, the bottom surface of the circular groove is provided with a mounting through hole, the measuring rod is fixedly mounted in the mounting through hole, a side wall of the sleeve is provided with a positioning through hole communicated with the mounting through hole, the positioning through hole is equipped with a top wire, the measuring rod comprises a cone pole and a positioning rod fixed on the large-diameter end surface of the cone pole, the positioning rod is matched with the mounting through hole, and a side wall of the positioning rod is provided with a positioning groove. The detection tool is advantaged in that the bottom surface of the sleeve is made to contact with the surface of a detected conic body, through adjusting depth of the measuring rod, a bottom end of the measuring rod is made to contact a side wall of the conic hole of the conic body, change of a top end of the measuring rod protruding out of or concaving into the surface ofthe sleeve is detected, whether the aperture of the conic body is qualified can be determined, detection is simple and convenient, and work efficiency can be effectively improved.

Description

technical field [0001] The invention belongs to the field of part processing, and relates to a measuring tool for measuring the diameter of a taper hole. Background technique [0002] In the production process of cone parts, there are cone holes on the surface of the cone parts. The aperture size of the cone holes determines the function performance of the parts. In the process of mass production of cone parts, the detection of the hole diameter of the cone parts is extremely important Importantly, the existing measuring tools for directly measuring the diameter are cumbersome, have low work efficiency, and have errors in the measurement. Contents of the invention [0003] The object of the present invention is to provide a measuring tool for the detection of taper hole diameter, the measuring tool is by contacting the bottom surface of the sleeve pipe with the surface of the detection cone, and then adjusting the depth of the measuring rod so that the bottom end of the me...
