Gauge and method for measuring diameter of large-sized steel wire bearing rail

Abstract

A gauge and method for measuring the diameter of a large-sized steel wire bearing rail comprises a body (1), a sleeve (3), a measuring head (4) and an elastic piece (6) which enables the body to move. The gauge and method for measuring the diameter of the large-sized steel wire bearing rail is characterized in that the body is composed of a large measuring cylinder (G), a measuring cylinder (E) and a connecting part (1-1), the measuring cylinder (E) and the connecting part (1-1) are connected on the left side and the right side of the large measuring cylinder (G), a first preset value measuring face (C) is arranged on the left end face of the large measuring cylinder, and a body measuring face (Y) is arranged at the outer end of the connecting part; the sleeve is provided with an axial hole (M) of the measuring cylinder (E), one end of the axial hole (M) is opened, the axial hole (M) is connected to the body in a sliding mode, a second preset value measuring face (B) is arranged at the opening end of the axial hole, and the other end of the sleeve is detachably connected with the measuring head (4) which is provided with a measuring head measuring face (X); the gap distance (A) between the first preset value measuring face and the second preset value measuring face is 5-10mm larger than the diameter difference of pore diameters at the two ends of a measured part and a rail hole, and the elastic piece is mounted between the bottom of the axial hole and the measuring cylinder. A limiting mechanism which limits the sliding range of the measuring cylinder is further arranged. Therefore, precision is high.

Description

technical field [0001] The invention relates to a measuring tool for mechanical processing, in particular to a gauge and a method for measuring the track diameter of a large-size steel wire bearing. Background technique [0002] In the stable rotating parts of some special machinery, the steel wire bearing system in which the steel ball slides on the steel wire is used. The core part is the steel wire bearing track part, and its diameter tolerance is very high, generally H7, and some are higher than H6, and its diameter tolerance is very high. The hole diameter is generally greater than 500mm, so it is not feasible to use the conventional fixed plug gauge for measuring the hole diameter. After such parts are processed, although they can be measured on a three-coordinate measuring machine, the measurement efficiency is too low and it is easy to scrap the parts. At present, there is no suitable measuring instrument for measuring this type of parts, and there is no reasonable ...

AI Technical Summary

Problems solved by technology

After the processing of such parts is completed, although they can be measured on a three-coordinate measuring machine, the measurement efficiency is too low, and it is easy to scrap the parts

At present, there is no suitable measuring instrument for measuring this type of parts, and there is no reasonable structure in the technical field of measuring the diameter of the track hole of a large-size steel wire bearing. Therefore, this type of gauge for measuring the track hole diameter of a large-size steel wire bearing design is very important
