The cylinder produced by our factory has a length of 3020mm, an outer diameter of φ93mm and an inner diameter of φ72mm. After the hot-rolled steel pipe is tempered, it needs to be straightened before machining. The straightness error of the workpiece axis is less than 1mm. When starting production, the straightness is measured by a self-made flat ruler, which is inconvenient to operate and is not easy to guarantee quality, and there are many waste products. To this end, I designed the straightness measuring device for the long rod type as shown in the figure.
