When the first stop plate slides, it continuously squeezes the first return spring. After the locking plate enters the locking groove, the first return spring provides a certain thrust, which is conducive to the replacement and installation of the step milling cutter and has high maintenance efficiency.

[0018] (2) After the auxiliary vibration damping ring seat is pressed down to the predetermined position, the traction bridge and the fitting are fitted and abutted against each other, and then the traction bridge enters the cutout groove. Then the limit bolt is screwed into the operating mounting block until it enters the threaded opening on the auxiliary vibration damping ring seat, which is conducive to the fixation of the step milling cutter and ensures the stability of use. Then the installed milling cutter disc is fixed to the driving mechanism of the milling equipment along with the supporting connecting plate. The rotating shaft is driven by the driving mechanism to rotate, and the driving gear is driven to rotate when the rotating shaft rotates. The rotation of the driving gear drives the limit tooth mouth to move, so that the auxiliary vibration damping ring seat rotates with it. After the auxiliary vibration damping ring seat rotates, it drives the milling cutter disc to rotate to process the workpiece to be milled. At the same time, the vibration damping sleeve and the positioning vibration damping rod can also limit and reduce the vibration of the milling cutter disc, which helps to stabilize the milling cutter disc after operation, improve the replacement efficiency, and reduce the impact of vibration.

When the traction bridge 21 rotates, it drives the reinforcing limit plate 9 to rotate in the direction close to the auxiliary vibration-damping ring seat 1, and slowly enters the catering sleeve groove 26 provided on the auxiliary vibration-damping ring seat 1. During the rotation of the reinforcing limit plate 9, it drives the fixed rod 33 to move in the restricted opening 25. When the reinforcing limit plate 9 moves, it continuously compresses the second return spring 24. Then, after the auxiliary vibration-damping ring seat 1 is pressed down to a predetermined position, the traction bridge 21 is fitted and conflicted with the fitting 22, and then the traction bridge 21 enters the incision groove 31, which is beneficial to multi-layer limitation, making the use of the milling cutter disc 11 more stable and improving the milling quality.
