[0037] In order to ensure that the flipping platform is in a horizontal state after flipping, it is also equipped with a clamping assembly to prevent the flipping from being incomplete. There are two groups of clamping assemblies, one of which is used to clamp the flipping platform before flipping, and the other is used to clamp the flipping platform after flipping.

[0039] In the initial state, one of the clamping components is pressed on the pressed block, and then the gear ring is placed on the flipping platform. After the positioning component is raised to be flush with the gear ring under the action of the jacking component, the positioning component works to adjust the position of the gear ring through the positioning block, and then the clamping component works to clamp the adjusted gear ring through the clamping block. After the positioning component is retracted, the jacking component descends, and after the jacking component descends, it does not affect the flipping of the flipping platform. Then the robot grinds one end of the inner tooth. After the grinding is completed, the clamping component is released, and then the flipping component works to flip the flipping platform. Then the other clamping component works to keep the flipping platform horizontal, and then the robot grinds the other end of the inner tooth. After the grinding is completed, the clamping component is released, and then the flipping component works to flip the flipping platform, so that the flipping platform returns to the initial state, and the clamping component works to keep the flipping platform horizontal. Then the clamping component is released, and the gear ring is taken out to complete the entire grinding process.
