Abstract: The utility model discloses a gear shaping fixture for a second shaft gear. A mandrel is composed of a connection plate, a conical surface section and a thread section, wherein the connection plate is connected with a transition plate, and the conical surface section and the thread section are used for sleeving the second shaft gear. An expansion sleeve is sleeved on the conical surface section, a pressing board is in clearance fit with the mandrel and is used for pressing the expansion sleeve, a nut is connected with the thread section of the mandrel, and the connection plate of the mandrel is provided with a first connection hole, a second connection hole, a third connection hole, a fourth connection hole, a fifth connection hole and a sixth connection hole, wherein the first connection hole, the second connection hole, the third connection hole and the fourth connection hole quarter a same circumference and are distributed on the same circumference to form a first set of connection holes, and the first connection hole, the fifth connection hole and the sixth connection hole trisect a same circumference and are distributed on the same circumference to form a second set of connection holes. According to the gear shaping fixture for the second shaft gear, not only can the investment on fixtures be reduced to reduce the manufacturing costs of the fixtures, but also time for changing the fixtures on two machine tools can be saved to improve working efficiency.
