Measurement auxiliary tool for warp distortion of shaft-class part

The utility model provides a measurement auxiliary tool for warp distortion of shaft-class parts and the measurement auxiliary tool comprises a vertical bracing frame. A first fixed shaft and a second fixed shaft horizontally extending are fixedly arranged on the bracing frame respectively. A first rotation sleeve and a second rotation sleeve are respectively sleeved on the first fixed shaft and the second fixed shaft. A first rolling assembly is mounted between the first rotation sleeve and the first fixed shaft. A second rolling assembly is mounted between the second rotation sleeve and the second fixed shaft. The first rotation sleeve and the second rotation sleeve are used for supporting the to-be-measured shaft-class parts together. Rotation of the to-be-measured shaft-class parts is realized by rotation of the first rotation sleeve around the first fixed shaft and rotation of the second rotation sleeve around the second fixed shaft. The tool provided by the utility model can stably support the shaft-cla
