High-precision reaming mechanism for steering nut

The utility model discloses a high-precision reaming mechanism for a steering nut, which belongs to the technical field of nut reaming, aims at solving the problem that the reaming precision of the nut is not high when the steering nut is reamed, and comprises a machining table, a machining frame is fixed on the side wall of the top end of the machining table, and a control cylinder is fixed on the side wall of one side of the machining frame. A connecting sleeve is arranged at the connecting end of the control air cylinder, a steering motor is fixed to the side wall of the bottom end of the connecting sleeve, the output end of the steering motor is connected with a mounting sleeve, and a reamer body is mounted in the mounting sleeve. Through the arrangement of the limiting mechanism, the rubber pad can clamp the two sides of a nut to be machined, so that displacement generated when the reamer body machines the nut is reduced, the nut reaming accuracy is improved, meanwhile, under the cooperation of the anti-
