[0035] Among them, the middle parts of the two ends of the opposite surfaces of the upper limit block 9 and the lower limit block 10 are provided with limiting grooves 14 corresponding to the connecting blocks 11, and the connecting blocks 11 are matched and fitted with the corresponding limiting grooves 14 on the upper limit block 9 and the lower limit block 10, and the first bolts 15 are in a vertical state.

The second bolts 16 penetrate the upper and lower surfaces of the corresponding positions on the grinding and polishing machine mounting plate 2, and the second bolts 16 help to install and limit the grinding and polishing machine mounting plate 2.

[0038] The working principle of the utility model is: during use, the lower surfaces of the grinding and polishing machine mounting plate 2 and the fixed block 3 are matched to the positions where the external horizontal precision grinding and polishing machine needs to be installed, so that the lower surfaces of the grinding and polishing machine mounting plate 2 and the fixed block 3 are respectively matched and fitted with the positions where the external horizontal precision grinding and polishing machine needs to be installed, and the grinding and polishing machine mounting plate 2 is further installed between the positions where the external horizontal precision grinding and polishing machine needs to be installed through the second bolt 16. The second bolt 16 can fix and limit the grinding and polishing machine mounting plate 2, which is convenient for the stable use of the grinding and polishing machine mounting plate 2. The grinding and polishing machine mounting plate 2 can fix and limit the fixed block 3 and the various components assembled on the fixed block 3, which is helpful for the stable use of the fixed block 3 and the various components assembled on the fixed block 3.

[0039] When it is necessary to adjust the position of the spindle body 1 for the workpiece to be ground and polished, the rotating motor 6 on the fixed block 3 is turned on, and the fixed block 3 can fix and limit the rotating motor 6, which is convenient for the stable use of the rotating motor 6. When the rotating motor 6 is turned on, the output shaft of the rotating motor 6 can drive the rotating rod 7 to rotate, and when the rotating rod 7 rotates, it can drive the screw 8 to rotate. The fixed block 3 can limit the screw 8 through the rotating rod 7, which is helpful for the stable rotation of the screw 8. When the screw 8 rotates, the moving block 5 threadedly connected to the screw 8 will move horizontally along the retention groove 4 on the fixed block 3. When the moving block 5 moves, it can drive the lower limit block 10 to move horizontally. When the lower limit block 10 moves horizontally, it can drive the clamping block 17 to move horizontally along the clamping groove 18 on the fixed block 3. The fixed block 3 can limit the lower limit block 10 through the clamping groove 18 and the clamping block 17, which is convenient for the stable movement of the lower limit block 10.

[0040] When the lower limit block 10 moves in the horizontal direction, it can drive the upper limit block 9 to move in the horizontal direction through the positioning groove 20, the positioning rod 19 and the first bolt 15. When the upper limit block 9 and the lower limit block 10 move in the horizontal direction, they can drive the spindle body 1 to move in the horizontal direction through the limiting groove 14 and the connecting block 11. Further, the workpiece that needs to be ground and polished is correspondingly assembled on the spindle body 1. When the spindle body 1 is moved in the horizontal direction, the workpiece that needs to be ground and polished can be driven to move, so as to move the workpiece that needs to be ground and polished to the position where it needs to be processed, which helps to adjust different workpieces that need to be processed at different positions, so as to ensure the applicable scope of use of this spindle.

[0041] When the spindle body 1 needs to be disassembled, the first bolt 15 is rotated and removed, so that the first bolt 15 cancels the limit between the upper limit block 9, the lower limit block 10 and the connecting block 11, and the upper limit block 9 is further moved upward to be removed. When the upper limit block 9 moves upward, it will drive the positioning rod 19 to move upward along the positioning groove 20 on the lower limit block 10. After the positioning rod 19 is moved to the outside of the positioning groove 20, the positioning between the upper limit block 9 and the lower limit block 10 will be cancelled, so that the limit groove 14 on the upper limit block 9 cancels the limit on the connecting block 11, and the spindle body 1 and the connecting block 11 are further moved upward to be removed, so as to disassemble the spindle body 1, which is convenient for replacing or repairing the spindle body 1.

[0042] After the spindle body 1 is replaced or repaired, the spindle body 1 is placed on the upper side of the limiting pad 13 in the arc groove 12 on the lower limit block 10, so that the connecting block 11 on the spindle body 1 enters the limiting groove 14 on the lower limit block 10, and the positioning rod 19 on the upper limit block 9 is further reset to the positioning groove 20 on the lower limit block 10, and the upper limit block 9, the lower limit block 10 and the connecting block 11 are installed and limited by the first bolt 15. The upper limit block 9 and the lower limit block 10 can limit the spindle body 1 through the limiting groove 14 and the connecting block 11, and the upper limit block 9 and the lower limit block 10 can limit the spindle body 1 through the limiting pad 13 in the arc groove 12, which is conducive to the stable use of the spindle body 1.

[0043] During use, it is helpful to move the main spindle body 1 and can conveniently adjust the position of the workpiece on the main spindle body 1 so as to adjust the position for different workpieces, which helps to ensure the applicable scope of the main spindle body 1 when in use.
