[0028] Please see Figures 3-4 A gear ring clamping device, the auxiliary component 2 includes an outer plate 21, a fixing frame 22, a clamping structure 23, a positioning plate 24, and an electric telescopic frame 25. The fixing frame 22 is embedded and fixedly connected to the inside of the outer plate 21. The rear end of the clamping structure 23 is connected to and movably engaged with the front end of the electric telescopic frame 25. The electric telescopic frame 25 is fixedly installed on the inner wall surface of the outer plate 21. The clamping structure 23 includes a clamping block q1, a first connecting block q2, a second connecting block q3, a tilting rod q4, and an assisting rod q5. One end of the clamping block q1 is hinged to the first connecting block q2. One end of the assisting rod q5 is hinged to the first connecting block q2, and the other end of the assisting rod q5 is hinged to and movably engaged with the tilting rod q4. The other end of the tilting rod q4 is hinged to the second connecting block q3. The outer plate 21 is embedded and fixedly connected to the outer plate 21. The clamping structure 23 is attached to the side of the carrier 1 and passes through the interior of the carrier 1 and moves to the inner side of the carrier 1. The second connecting block q3 is fixedly connected to the front end of the electric telescopic frame 25. The assist rod q5 moves to the top of the fixed frame 22. The tilting rod q4 and the assist rod q5 are a group that work together in a symmetrical structure and can move relative to each other to provide power for the swing of the clamping block q1. The outer plate 21 has two locations and is symmetrically arranged with respect to the carrier 1. Inside each location, there is a fixed frame 22, a clamping structure 23, and an electric telescopic frame 25. The clamping block q1 moves to the inner side of the carrier 1 and the four clamping blocks q1 form a ring. After deformation, the inner ring diameter can be changed to accommodate the clamping of gear rings of different specifications.

[0029] Please see Figure 5A gear ring clamping device is disclosed. The clamping block q1 includes an anti-slip block q11, an arc frame q12, a spring q13, and a connecting block q14. The anti-slip block q11 is embedded and movable on one side of the arc frame q12. One end of the anti-slip block q11 is hinged to the top position inside the arc frame q12.

[0030] In summary, by adding an auxiliary component 2 to the outside of the carrier frame 1, the gear ring placed inside the carrier frame 1 can be clamped, providing a stable force. Then, by rotating the carrier frame 1, the gear ring inside the carrier frame 1 is processed under rotation. The auxiliary rotating block 4 assists on the outer end face of the carrier frame 1, making the rotation smoother. Through the provided clamping structure 23, after the gear ring is placed inside the carrier frame 1, the operator can operate and adjust the clamping structure 23 according to the diameter and width of the gear ring. Activating the electric telescopic frame 25 causes its front end to drive the second connecting block q3 to move under telescopic deformation, generating a thrust on the tilting rod q4, causing the tilting rod q4 to tilt. Then, one end of the assist rod q5 is also affected by the tilting rod. The deformation force of q4 causes it to tilt. One end of the assist rod q5 is connected to the connecting block q14 through the first connecting block q2. When the assist rod q5 tilts, the force on its other end drives the connecting block q14, causing the arc frame q12 to swing at a fulcrum. The four clamping blocks q1 can thus change their angle. The ring shape formed by the four clamping blocks q1 changes, which makes it easier to adapt to toothed rings of different diameters and widths. The toughness and anti-slip properties of the anti-slip block q11 can also better adhere to the outer edge of the toothed ring. With the elastic cooperation of the spring q13, it better assists the clamping blocks q1 in clamping the toothed ring, so that the toothed ring has a better positional stability force inside the carrier 1.
