For example, patent application number CN201410243127.6 describes a positioning fixture for processing a stepped gear ring, which includes a fixture body. The gear ring consists of an upper ring and a lower ring. The outer diameter of the upper ring is the same as that of the lower ring, and the inner diameter of the upper ring is smaller than that of the lower ring. The fixture body includes a base plate. A cylindrical positioning boss is provided at the center of the base plate. The height of the positioning boss is the same as that of the lower ring of the gear ring, and the outer diameter of the positioning boss is the same as the inner diameter of the lower ring of the gear ring and larger than the inner diameter of the upper ring of the gear ring.
