[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1 As shown, a smoke exhaust window processing and polishing device includes an outer housing 1 fixedly mounted on an operating table by bolts. Inside the outer housing 1 is an eccentric sleeve 2 that can move left and right along its central axis. A pneumatic rotor 3 is movably sleeved inside the eccentric sleeve 2. Figure 4 As shown, one side of the outer surface of the eccentric sleeve 2 is provided with an air inlet groove 4 and an exhaust groove 5, which are respectively connected to its inner cavity. The air inlet groove 4 is connected to an air inlet pipe 8 fixedly installed on the outer shell 1. At the same time, the other end of the air inlet pipe 8 is connected to an external air pressure pump. High-pressure airflow is then squeezed and delivered into the inner cavity of the eccentric sleeve 2 through the air inlet pipe 8 and the air inlet groove 4, which drives the pneumatic rotor 3 to rotate. The pneumatic rotor 3 is fixedly sleeved with a drive shaft 6, whose two ends extend to the outside of the eccentric sleeve 2. A grinding head 10 for grinding the smoke exhaust window is fixedly installed on the left end of the outer surface of the drive shaft 6. Figure 3 As shown, a first conical disk 7 is fixedly sleeved on the right end of the outer surface of the drive shaft 6, and a second conical disk 9 is fixedly sleeved on the right side of the inner cavity of the outer shell 1. The inclined surfaces of the first conical disk 7 and the second conical disk 9 correspond to each other, and a set of linear grooves are respectively provided on their inclined surfaces, and a ball is provided inside the linear grooves.

[0022] Further, when the first conical disc 7 rotates with the rotation of the eccentric sleeve 2, the ball is forced to move outward along the trajectory of the linear chute under the action of centrifugal force, and the polishing head 10 on the transmission shaft 6 is reversely extruded to move to the left side, so as to compensate for the loss of the polishing head 10 when polishing the smoke exhaust window, and ensure the effective contact pressure of the polishing head 10 on the smoke exhaust window.

[0023] As shown in Figure 4 , in the technical solution, the eccentric sleeve 2 and the pneumatic rotor 3 form an eccentric sleeve joint, and a plurality of baffle plates are arranged on the outer surface of the pneumatic rotor 3. Further, the space between the eccentric sleeve 2 and the pneumatic rotor 3 is formed into a plurality of independent sealed spaces through the baffle plates, so that the pneumatic rotor 3 changes the size of the plurality of independent sealed spaces on it through the contraction of the baffle plates on it during the eccentric rotation in the inner cavity of the eccentric sleeve 2, and forces the pneumatic rotor 3 to rotate at high speed during the continuous intake and exhaust process. Compared with the traditional impeller mechanism, the pneumatic rotor 3 on the polishing equipment has higher transmission torque.

[0024] As shown in Figure 2 , Figure 3 , in the technical solution, the gap between the corresponding inclined surfaces of the first conical disc 7 and the second conical disc 9 gradually decreases outward, so that when the ball on it moves outward under the action of centrifugal force, the displacement amount of the transmission shaft 6 and the structure on it to the left side is effectively increased, and the loss compensation of the polishing head 10 on the polishing equipment can be stably triggered, and the stability and reliability are higher.

[0025] As shown in Figure 3 , in the technical solution, the adjusting sleeve 11 is threadedly connected to the left side of the inner cavity of the outer shell 1, and the spring member 12 is arranged between the adjusting sleeve 11 and the end of the eccentric sleeve 2. The pressure of the spring member 12 on the eccentric sleeve 2 can be adjusted by rotating the adjusting sleeve 11, so that in the initial state, a rightward extrusion force can be applied to the pneumatic rotor 3 to balance the leftward movement pressure of the transmission shaft 6 caused by the centrifugal force of the first conical disc 7 during high-speed rotation, so that the surface of the smoke exhaust window will not be excessively polished.

[0026] In the technical solution, the control valve is arranged on the air inlet pipeline 8, so that the flow of high-pressure gas into the inner cavity of the eccentric sleeve 2 is adjusted through the control valve, thereby adjusting the rotation speed of the pneumatic rotor 3 driving the transmission shaft 6, and the polishing equipment is suitable for different polishing environments.
