s5, reversing the fine grinding cylinder: the controller controls the second cylinder to be electrified and extended to push the brake rod to do arc motion, the brake rod pushes the brake disc and the connecting pipe to compress the elastic cover, so that a return spring in the brake rod is compressed, the push rod pushes the backing plate and the friction disc to apply friction force to the flywheel, the flywheel stops outputting power to the output shaft, meanwhile, the controller controls the third motor to be electrified to drive the third rotating wheel to rotate, under the transmission action of the second transmission belt, the second rotating wheel drives the rotating sleeve to rotate to enable the coarse grinding cylinder and the fine grinding cylinder to change positions, the fifth gear is meshed with the sixth gear, after the position change, the second cylinder contracts, the elastic cover and the return spring are successively reset, the connecting pipe, the brake disc, the backing plate and the friction disc also reset, and the flywheel resumes transmission to the output shaft;
s6, grinding and polishing the column tube for the second time: after the fine grinding cylinder reaches the position of the coarse grinding cylinder; polishing the column tube again by using the mode of the step S4;
s7, column tube replacement end: after the pillar tube is polished, the controller controls the first air cylinder close to the polishing device to enable the second clamping seat to move away from the first clamping seat again, meanwhile, the positions of the coarse polishing cylinder and the fine polishing cylinder are changed again, an operator changes the other end of the pillar tube to be inserted into the first polishing cavity, and the other end of the pillar tube is polished in the mode of S4-S6;
s8, pushing the column tube: after the column tube is polished, the controller controls the two first air cylinders to enable the two second clamping seats to move away from the two first clamping seats again, an operator takes out the polished column tube, the controller controls the first motor to be electrified to drive one second gear and one second pushing shaft to rotate, one second gear is in tooth meshing with one first gear, one first gear and the second pushing shaft are enabled to rotate in different directions with one second gear and one second pushing shaft, the second pushing shaft also drives the first rotating wheel on the surface of the second pushing shaft to rotate along with the first rotating wheel, the other first gear is enabled to rotate along with one first gear through the transmission of the first transmission belt, the other first gear is in tooth meshing with the other second gear, the other second gear is enabled to rotate in different directions with the other first gear, and the other second gear rotates along with the same direction with one second gear, therefore, two first pushing wheels and two second pushing wheels can push and insert the unfinished column tube into the first grinding cavity, and the steps S2-S7 are repeated to grind and polish the unfinished column tube.
