[0013] Compared with the prior art, the present invention provides a coaxiality inspection tool for the inner and outer circles of a half-axle sleeve, which has the following beneficial effects:

[0014] In the technical solution disclosed by the utility model, a positioning ring, a threaded rod, a curved plate, a guide frame and a calibration component are used in combination.
