The utility model relates to the field of coaxiality detection, in particular to a main shaft coaxiality detection device, which comprises a workbench. The utility model aims to solve the problem that the coaxiality of the air expansion shaft can be ensured as much as possible only by rotating the two fixing bolts at the same time when the side surface of the air expansion shaft is pressed against and fixed through a fixing head and the two fixing bolts, so that a user is troublesome to fix the air expansion shaft. According to the device, the main shaft needing to be detected is placed in the fixed pipe, and then the internal threaded pipe is rotated, so that the eight telescopic rods on the inner side of the internal threaded pipe are divided into two groups and deflect at the same time to annularly abut against and fix two positions of the side face of the main shaft, and the distances between all the positions of the side face of the main shaft and the inner wall of the fixed pipe are equal; compared with
