A method for using a grinding and polishing device for flange polishing, according to a grinding and polishing device for flange polishing according to any one of claims 1 to 8, characterized in that: The method of use comprises the following steps: The electric push rod (4) is controlled to retract so that the movable seat (2) moves away from the grinding frame (5) in the rectangular groove (102), the flange is placed on the top of the movable seat (2) and clamped on the top of the rotating disk (3), the locking screw sleeve (313) is loosened to control the locking stud (312) to rotate, and the adjusting bevel gear (311) is driven to rotate in the installation groove (308), and the two sets of adjusting screws (311) are controlled to rotate under the meshing action of the adjusting bevel gear (311) and the adjusting bevel gear (309). The adjusting screw (304) is rotated synchronously, so that the movable plate (306) on the surface of the limit rod (305) slides inside the installation groove (303), until the movable plate (306) drives the clamping top block (307) to be close to the inner wall of the flange, the flange is clamped and fixed on the top of the rotating disk (3), and the locking screw sleeve (313) is tightened to be close to the top of the rotating disk (3) to lock and fix the locking stud (312), so that the adjusting screw (304) will not rotate at will; The rotating motor (204) and the grinding motor (503) are started, so that the rotating bevel gear 1 (205) at the output end of the rotating motor (204) drives the rotating bevel gear 2 (301) to rotate synchronously, and drives the flange clamped and fixed on the top of the rotating disk (3) to rotate synchronously, and at the same time, the rotation of the grinding motor (503) is transmitted through the grinding bevel gear 1 (502) and the grinding bevel gear 2 (504), driving the grinding belt (505) to slide on the surfaces of the two sets of grinding rollers (501); The electric push rod (4) is controlled to extend, and the movable seat (2) is pushed to slide inside the rectangular groove (102), and the flange at the top of the movable seat (2) is clamped and fixed on the top of the rotating disk (3) to approach the grinding belt (505), until the surface of the flange is pressed against the surface of the grinding belt (505), and the grinding belt (505) is pushed and squeezed to deform, so that the grinding belt (505) away from the flange side is gradually straightened and the pressing roller (605) is lifted, so that the pressing roller (605) pushes the mounting frame (603) in the moment. The surface of the mounting column (602) inside the shaped slide groove (601) slides, squeezing the compression spring (604) to deform, and under the rebound effect of the compression spring (604), the mounting frame (603) pushes the compression roller (605) to press on the surface of the grinding belt (505), so that the grinding belt (505) is in a straightened and taut state, and at the same time, the rotating motor (204) controls the rotating disk (3) to drive the flange to rotate on one side of the grinding belt (505), thereby grinding and polishing the flange surface.
