[0037] In some technical solutions, the bottom of the positioning platform 1 is equipped with a support base 5.

[0038] In this technical solution, the positioning platform 1 is supported and fixed by the bearing base 5.

[0039] Working process and principle: In use, place the grinding plate 15 to be ground within the two grinding limit brackets 6 and rest it against the protective plate 19. Then, rotate the clamping bolt 17, and under the action of the clamping screw hole 16, screw the clamping plate 18 inward until the grinding plate 15 is clamped. During the clamping process, the telescopic rod 25 can retract after contacting the clamping plate 18 with the grinding plate 15 until the clamping bolt 17 is rotated to the correct position to clamp the grinding plate 15. Then, the servo motor 7 controls the two sliding... The ball screw inside the track rotates, controlling the positioning seat a8 and positioning seat b3 to move synchronously in the same direction, which can drive the identifier 9 and the infrared generator 2 to move synchronously. While sliding, when the identifier 9 and the infrared generator 2 move to the grinding hole opened at the grinding plate 15, the identifier 9 will sense each other through the grinding hole and the infrared generator 2. At this time, the movement stops, the electric push rod 10 is extended, and the grinding motor 12 is started at the same time, so that the grinding roller 13 can be inserted into the grinding hole on the grinding plate 15 for grinding.
