[0020] See also Figures 1 to 3 , a cone-turning machine, comprising a main frame 1. The left and right sides of the main frame 1 are connected to a lifting assembly, which comprises a base 2. A ball screw assembly is provided on the base 2, and the main frame 1 is driven by the ball screw assembly to rise and fall. The ball screw assembly comprises a ball screw 3, and the rear end of the ball screw 3 is connected to the second hand wheel 4. A connecting rod 6 is fixedly connected to the screw nut 5, and sliders 7 are installed at both ends of the connecting rod 6. The slider 7 is fixedly connected to the main frame 1 through a connecting shaft 8. The slider 7 is arranged in the slide rail of the base 2, and a groove corresponding to the slider 7 is opened on the side of the base 10. A locking nut 17 is installed on the groove to position the slider 7. The locking nut 17 extends into the groove and is screwed into the slider 7 to fix the position of the slider 7. When the height of the main frame 1 needs to be adjusted, the reducing nut is unscrewed and the second hand wheel 4 is adjusted. The second hand wheel 4 drives the ball screw 3 to rotate, so that the screw nut 5 moves up and down, and synchronously drives the slider 7 to move up and down on the slide rail. When it is adjusted to the appropriate position, the locking nut 17 is screwed in again, and the slider 7 is locked to complete the adjustment of the lifting assembly height.

[0021] An optical axis 9 is symmetrically arranged on the main frame 1. A grinding assembly is mounted on the optical axis 9. This assembly includes a base 10 movably mounted on the optical axis 9, with a rack 11 mounted on the base 10. A translation assembly is also mounted on the main frame 1. A gear 12 of the translation assembly engages with the rack 11, and rotation of the gear 12 drives the rack 11 to translate. A grinding head 13 and a grinding wheel 14 are mounted on the base 10. The translation assembly also includes a first handwheel 15. Gear 12 is connected to the upper end of the first handwheel 15. Rotating the handwheel drives the rack 11 to translate via gear 12. The base 10 is movably connected to the optical axis 9 via a linear bearing 16. To adjust the horizontal position of the grinding head 13 and grinding wheel 14, simply rotate the first handwheel 15, which drives the rack 11 left and right via the gear 12 on the handwheel. This adjusts the grinding head 13 and grinding wheel 14 to the desired position.

[0022] The base 10 is equipped with a drive component for driving the grinding head 13 to rotate. The grinding wheel 14 is connected to the grinding head 13 so as to rotate synchronously with the grinding head 13. The drive component adopts conventional motor control, and the speed of the grinding head 13 and the grinding wheel 14 can be controlled by electronic control. The above control is all existing technology and will not be repeated here.

[0023] When in use, connect the bases 2 on both sides to the rolling mill, adjust the height and horizontal position, start the power supply, and the grinding wheel 14 and the grinding head 13 can complete the grinding operation. The grinding head 13 is driven by the first hand wheel 15 to move back and forth to grind the roller surface.

[0024] Of course, conventional driving components such as a reduction motor may be selected to replace the first hand wheel 15 and the second hand wheel 4 to achieve automated control.
