Coaxiality detection device for inner ring of wind power locking disc

The utility model relates to the technical field of wind power locking discs, in particular to a coaxiality detection device for an inner ring of a wind power locking disc. The coaxiality detection device is characterized by comprising a base, a supporting device and a dial indicator, the top surface of the base is an inclined surface consistent with the taper of an outer cone of an inner ring ofthe wind power locking disc; at least two sets of supporting devices used for stably supporting the outer wall face of an inner ring of the wind power locking disc are arranged on the top face of thebase. Each set of supporting device comprises two supports which are arranged in a spaced mode. The support is correspondingly connected with the top face of the base in a fastened mode. A through hole is formed in the top of the support, a pin shaft is tightly inserted into the through hole, one end of the pin shaft is provided with a step face correspondingly abutting against one side wall faceof the support, the other e
