[0030] A first bidirectional lead screw 17 is rotatably connected to the inner surface of the fixed plate 14. A rotating block 18 is fixedly connected to the left end of the first bidirectional lead screw 17. A moving block 20 is threadedly connected to the outer surface of the first bidirectional lead screw 17. A connecting seat 21 is fixedly connected to the outer surface of the moving block 20. A connecting post 22 is fixedly connected to the outer surface of the connecting seat 21. A connecting strip 23 is rotatably connected to the outer surface of the connecting post 22. A fixed post 24 is rotatably connected to the inner surface of the connecting strip 23. A fixed seat 25 is fixedly connected to the lower end of the fixed post 24. An insert block 26 is fixedly connected to the outer surface of the fixed seat 25. A slot 27 is provided on the outer surface of the fixed plate 14. A snap-fit ​​plate 28 is slidably connected to the inner surface of the slot 27. A placement platform 29 is fixedly connected to the upper surface of the buckle plate 28. A third motor 30 is fixedly connected to the right surface of the placement platform 29. A second bidirectional lead screw 31 is fixedly connected to the output end of the third motor 30.

There are two clamping plates 32 and they are symmetrically distributed. The third motor 30 is electrically connected to an external power source.

[0031] Working principle: During operation, firstly, rotating the rotating block 18 drives the first bidirectional lead screw 17 to move the two moving blocks 20 along opposite threads on the rotating block 18, causing them to move away from each other. This, combined with the linkage of the connecting seat 21, connecting column 22, connecting bar 23, fixing column 24, and fixing seat 25, causes the two insert blocks 26 to disengage from their corresponding insertion holes 19, thus releasing the restraint on the buckle plate 28. Then, the entire fixture structure is removed along the inside of the slot 27. Next, according to the requirements of the workpiece, the buckle plate 28 on the corresponding fixture is inserted into the slot 27. Then, rotating the rotating block 18 in the opposite direction causes the two insert blocks 26 to insert into their corresponding insertion holes 19, thus completing the installation of the new fixture. This is simple and convenient, requiring no tools. The workpiece to be ground is then placed in the designated area. On platform 29, the third motor 30 is started, driving the second bidirectional lead screw 31 to move the clamping plates 32 on both sides toward each other, thus clamping the workpiece. Then, the second motor 7 and the first motor 3 are started. Under the action of the second motor 7, the second rotating shaft 8 drives the grinding roller 9 to rotate at high speed. Under the action of the first motor 3, the first rotating shaft 4 drives the high-speed rotating grinding roller 9 to move downward through the slider 5, making contact with the surface of the workpiece, thereby performing a grinding operation on the workpiece. Subsequently, as needed, the turntable 12 is rotated, driving the connecting shaft 10 to drive the gear 11 to rotate. Under the meshing action of the gear 11 and the toothed plate 16, the workpiece on the fixed plate 14 can be moved left and right through the connecting block 15, thus facilitating the worker to perform comprehensive grinding on the surface of the workpiece.
