The power mechanism included in the workbench 2 can be used to drive the turntable 3 to rotate inside the workbench 2. The connection between the base 8 and the workbench 2 is used to ensure the stability of the structure. When the cylindrical part is completed, the movable frame 12 is used to slide inside the movable box 11 to make the grinding turntable 15 contact the outside of the cylindrical part. The movable frame 12 is used to ensure the stability of the drive motor 13 and the transmission rod 14. The drive motor 13 is started and the output shaft of the drive motor 13 is used to drive the transmission rod 14 to rotate. The rotation of the transmission rod 14 is then used to drive the grinding turntable 15 to rotate outside the cylindrical part to achieve the grinding operation of its outer wall. The hydraulic push rod 9 can be used to push the movable box 11 up, so that the worker can adjust the position of the movable box 11 according to the height of the cylindrical part, which can meet the grinding requirements of cylindrical parts of different heights, and then complete the grinding work of the cylindrical part, which can reduce the physical labor of the workers and improve the efficiency of the device.

[0020] Further, such as Figure 2 and Figure 3As shown, the four corners of the bottom of the movable box 11 are fixedly connected with a positioning rod 10, and the bottom of each positioning rod 10 is slidably connected to the inner wall of the base 8. Two second slide grooves 16 are provided inside the movable box 11, and the two second slide grooves 16 are symmetrically arranged. A second rack 20 is slidably connected to the inside of each second slide groove 16, and one side of each second rack 20 is fixedly connected to the movable frame 12.

The rotation of the threaded rod 7 drives the limit rod 4 to slide inside the slide groove 6, so that one side of the limit rod 4 fits the inner wall of the cylindrical component. When the cylindrical component is completed, the two small motors 22 inside the movable box 11 are started, and the two small motors 22 are used to drive the gear 21 to rotate at the same time, so that the gear When rotating, the second rack 20 is driven to slide inside the second chute 16, thereby driving the movable frame 12 to slide inside the movable box 11. When the grinding turntable 15 contacts the outside of the cylindrical component, the electric push rod 19 is started, and the electric push rod 19 is used to push the block 18 to move, so that one side of the block 18 is engaged with one side of the rack 17, so that the movable frame 12 is fixed inside the movable box 11.
