Asymmetric hub spigot measuring tool and measuring method

The invention discloses an asymmetric hub spigot measuring tool, which belongs to the technical field of automobile spare parts, and comprises a supporting main body and a measuring meter, the supporting main body is a non-closed circular ring, and the measuring meter is rotatably arranged on a first main body; and a first supporting block and a second supporting block which are fixedly arranged on the second main body are matched with a measuring meter to measure the five-equal-part hub spigot. The invention also provides an asymmetric hub spigot measuring method using the measuring tool, which comprises the following steps of: firstly, measuring the standard component zero setting measuring meter by using the measuring tool, measuring the distance between the second fulcrum and the measuring head of the measuring meter, then measuring the five-equal-part hub spigot to obtain the reading of the measuring meter, and finally establishing a coordinate system by taking the circle center of the standard component
