Tool for measuring outer diameter of cylinder component

Abstract

The invention relates to the technical field of measuring tools, in particular to a tool for measuring the outer diameter of a cylinder component, which comprises a first measuring assembly and a second measuring assembly, the second measuring assembly comprises a main body piece which is movably matched with the measuring rod; and the calibration assembly comprises a calibration piece matched with the measuring rod and the main body piece. The beneficial effects of the invention are that the first measurement assembly and the second side face assembly are installed, the calibration assembly is clamped into the main body, the measurement rod is moved to make the measurement rod contact with the calibration piece surface zero setting device, and after the calibration assembly is taken down, the to-be-measured cylinder larger than the radius of the main body piece is clamped to the two sides of the inner wall of the main body piece. The external diameter measuring device has the advantages that the operation is simple and convenient, the size can be measured by a small person, the operation can be carried out by a single person, the measuring precision is ensured, and the like.
