When the support component 3 is working, the toothed belt 6 can be used to drive the rotating rod 52 to rotate, and the rotating rod 52 drives the screw 54 to rotate through the cooperation of the driving gear 53 and the driven gear 55. After the staff removes the pin 56, the moving block 571 slides to cooperate with the screw 54 thread, so that the polishing component 57 moves back and forth on the screw 54.

The high-speed motor 576 drives the polishing wheel 575 to rotate rapidly, thereby polishing the surface of the continuous casting roller. The rotation direction of the polishing wheel 575 is opposite to that of the continuous casting roller, which can increase the polishing efficiency. When there are two thinner sections at both ends of the continuous casting roller to be processed, when the polishing assembly 57 moves to the thin section, the polishing wheel 575 contacts the surface of the continuous casting roller due to gravity. At this time, the polishing assembly 57 can be moved back and forth in the thin section by controlling the drive motor 38.

[0032] The support assembly 3 includes a support plate 31, and a hydraulic rod 32 is symmetrically arranged on the outside of the support plate 31. The top of the hydraulic rod 32 is fixedly connected to an arc plate 33, and the inner wall of the arc plate 33 is rotatably connected to a pulley 34. A push rod 35 is arranged above the pulley 34. The outer wall of the push rod 35 is rotatably connected to a pressure plate 36, and the inner wall of the pressure plate 36 is slidably connected to a ball 37. A drive motor 38 is arranged on the outside of the ball 37. The output end of the drive motor 38 is fixedly connected to a rotating shaft 39, and the end of the rotating shaft 39 away from the drive motor 38 is fixedly connected to a push rod 310. The overall cross-sectional area of ​​the push rod 310 is smaller than the cross-sectional area of ​​the rotating shaft 39. The push rod 310 contacts the surface of the continuous casting roller to increase the pressure. The bottom of the support plate 31 is fixedly connected to the inner wall of the machine body 1. The machine body 1 The inner wall of the machine body 1 is fixedly connected to the bottom of the hydraulic rod 32, the outer wall of the push rod 35 is threadedly connected to the inner wall of the machine body 1, and the inner wall of the machine body 1 is rotatably connected to the outer wall of the rotating shaft 39 through a bearing. The staff rolls the continuous casting roller onto the support plate 31, and the hydraulic rod 32 works to align the axis of the continuous casting roller with the axis of the rotating shaft 39 and the pressure plate 36. The staff rotates the push rod 35 to clamp the two ends of the continuous casting roller with the ball 37 and the push rod 310, and then drives the motor 38 to work, and drives the continuous casting roller to rotate through the rotating shaft 39 and the push rod 310. The balls 37 on the pressure plate 36 except the center ball 37 can rotate in the pressure plate 36 with the rotating continuous casting roller, and the ball 37 at the center rotates with the axis of the continuous casting roller, which can reduce the friction of the continuous casting roller when it rotates.

[0033] Working principle:

[0034] When in use, the staff opens the baffle 8 and inserts the grinding plate 4 of appropriate thickness into the machine body 1, that is, the distance between the bottom of the grinding plate 4 and the axis of the rotating shaft 39 is slightly smaller than the radius of the continuous casting roller to be processed. The staff puts the continuous casting roller on the push plate 2 and pushes it into the machine body 1 to make it roll onto the support plate 31 in the support assembly 3. Then the hydraulic rod 32 works to make the arc plate 33 rise so that the pulley 34 contacts the surface of the continuous casting roller. After the hydraulic rod 32 continues to work to align the axis of the continuous casting roller with the axis of the rotating shaft 39 and the pressure plate 36, the hydraulic rod 32 stops working. The staff rotates the push rod 35 to drive the pressure plate 36 to move into the machine body 1 until the balls 37 on the pressure plate 36 and the push rod 310 on the rotating shaft 39 clamp the two ends of the continuous casting roller, and then the driving motor 38 works to drive the continuous casting roller to rotate through the rotating shaft 39 and the push rod 310. The balls 37 on the pressure plate 36 except the center ball 37 can rotate in the pressure plate 36 with the rotating continuous casting roller. The ball 37 at the center rotates with the axis of the continuous casting roller, which can reduce the friction force on the continuous casting roller during rotation, and the surface of the rotating continuous casting roller is polished by the polishing plate 4.

[0035] When the continuous casting roller is polished by the polishing plate 4, the polishing assembly 57 is in a smooth section on the screw 54, and the latch 56 is used to prevent it from cooperating with the thread. Then the rotating shaft 39 drives the rotating rod 52 to rotate through the toothed belt 6 in the protective shell 51. When the rotating rod 52 drives the screw 54 to rotate through the cooperation of the driving gear 53 and the driven gear 55, the polishing assembly 57 does not work and does not move; when the surface of the continuous casting roller is polished, the driving motor 38 stops working, and the fine treatment assembly 5 is used to polish the continuous casting roller. The staff opens the baffle 8 and removes the polishing plate 4. Then the T-shaped plate 573, the high-speed motor 576 and the polishing wheel 575 drop due to gravity and pull down the connecting rod 572 and the spring 574, and the polishing wheel 575 can contact the surface of the continuous casting roller. After the staff removes the latch 56, the moving block 571 slides to cooperate with the screw 54 thread, and the driving motor 38 works again. Similarly to the above, it drives the screw 54 to rotate. At the same time, the high-speed motor 576 drives the polishing wheel 5 75 rotates quickly to grind the continuous casting roller, and the polishing wheel 575 rotates in the opposite direction to the continuous casting roller, which can increase the polishing efficiency. The drive motor 38 is controlled to rotate forward and reversely, so that the polishing component 57 moves back and forth on the screw 54. When there are two thinner sections at both ends of the continuous casting roller to be processed, when the polishing component 57 moves to the thin section, the polishing wheel 575 contacts the surface of the continuous casting roller due to gravity. At this time, the polishing component 57 can be moved back and forth in the thin section by controlling the drive motor 38. After grinding a thin section, the drive motor 38 and the high-speed motor 576 stop working, and the staff lifts the lower half of the polishing component 57 so that its bottom contacts the thick section of the continuous casting roller. Then the drive motor 38 and the high-speed motor 576 work again and process another thin section; after grinding and polishing the continuous casting roller, the staff can pass the debris in the body 1 out of the discharge port 7, and when the continuous casting roller is processed, the staff can flip up the push plate 2 so that it can block the debris from flying out.

[0036] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
