Abstract

The invention discloses a large pipe end face small circular boss flatness measuring tool which comprises a support device and a radial guide rod assembly. The support device comprises a center cylinder, a center ring arranged at the periphery of the bottom end of the center cylinder and at least three groups of support adjusting rod devices. The supporting adjusting rod devices comprise adjustingrods and supporting rods, ends of the supporting rods are connected with the periphery of the center ring, the other ends of the supporting rods are telescopically connected with cambered surface base plates used for being connected with the inner circular surfaces of the pipelines, ends of the adjusting rods are connected with the center cylinder, and the other ends are connected with the supporting rods through adjusting assemblies; the adjusting assemblies are used for adjusting the distances between the supporting rods and the adjusting rods. The radial guide rod assembly comprises a guide rod, the guide rod is perpendicular to the axis of the center cylinder, the guide rod is rotatably connected to the top end of the center cylinder through a rotating assembly, and the guide rod is further connected with a lever indicator for measurement. The tool is convenient to measure, and the measurement error can be controlled within an extremely small range.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a tool for measuring the flatness of a small circular boss on the end face of a large pipe. Background technique [0002] The piece to be tested is a large pipe fitting for power equipment, and the end surface of the pipe fitting is evenly distributed with many small round bosses, and the flatness of each small round boss needs to be measured. Due to the large diameter and heavy weight of the pipe, it is inconvenient to carry, and the conventional measurement method is incompetent, so it needs to be measured with the aid of suitable measuring tools. Contents of the invention [0003] The purpose of the present invention is to provide a tool for measuring the flatness of the small circular boss on the end face of a large pipe to solve the problem of difficulty in measuring the flatness of the boss on the end face of a large pipe fitting in the prior art. [0004] In order t...
