They are suitable for processes such as milling and grinding, and can accurately position gears, counteract cutting forces, and improve machining accuracy and efficiency. They are important equipment for ensuring consistency in mass production of gears.

[0003] Chinese patent publication number CN208991898U discloses a bevel gear clamp, including an annular base plate, an annular guide ring, a push rod, and a push rod. The guide ring is fixed on the base plate, and the central axis of the guide ring is in the same straight line as the central axis of the base plate. The push rod is used to press against the inner wall of the bevel gear blank, and the push rod passes through the guide ring. At least three push rods are radially evenly distributed on the guide ring. The push rod is used to push the push rod to move. A conical push head is fixed to the end of the push rod facing the guide ring, and the end facing away from the guide ring is fixedly connected to the push rod of the push cylinder.

[0004] In the bevel gear clamp provided by this patent, the gear is limited and fixed by the abutment rod. However, for bevel gear blanks with complex shapes, it may be difficult to ensure that the contact pressure between each abutment rod and the inner wall of the blank is completely consistent.
