[0026] Furthermore, a cleaning groove 20 is arranged on one side of the bottom end of the polishing groove 2, and a collecting box 21 is placed inside the base 1 below the cleaning groove 20. By sweeping, the debris generated by polishing inside the polishing groove 2 falls into the collecting box 21 through the cleaning groove 20, thereby cleaning the debris.

[0027] The method of using the present embodiment is as follows: when in use, firstly, the length of the connecting rod 1001 and the connecting rod 2 1002 is adjusted according to the size of the automobile inner frame component to be polished, and the connecting rod 1001 and the connecting rod 2 1002 are locked using the locking bolt 1004, the automobile inner frame component is located on the supporting plate 11 and between the two clamping plates 9, and then the electric push rod 4 is controlled to descend, and the electric push rod 4 drives the moving plate 5 and the movable plate 6 to descend, so that the grinding wheel 8 contacts the automobile inner frame component, and at the same time the movable plate 6 compresses the elastic spring 15, so that the grinding wheel 8 and the automobile inner frame component are in contact with each other. The frame parts maintain appropriate contact pressure, and the grinding wheel 8 is driven to rotate by the driving motor 22 to achieve the grinding of the internal skeleton parts of the automobile. Under the action of the rotating wheel 16, the internal skeleton of the automobile can be moved inside the polishing tank 2 to achieve comprehensive polishing of the internal skeleton parts of the automobile.
