[0018] A rotating shaft 4 is arranged at the bottom of the fixed frame 21, and the specific connection structure between the rotating shaft 4 and the fixed frame 21 is that a bearing seat 23 and a bearing plate 24 are arranged at the left and right sides of the fixed frame 21 respectively, the bearing seat 23 is fixed on the left end bottom wall of the fixed frame 21 through connecting bolts, two first check nuts 211 are threadedly connected at the front and rear ends of the fixed frame 21 respectively, the four first check nuts 211 abut against the front and rear side walls of the bearing seat 23 respectively, bearings are arranged at the left and right ends of the bearing seat 23, the left end of the rotating shaft 4 passes through the two bearings in the bearing seat 23 and is connected with the secondary belt pulley 41, a transmission belt 5 is arranged between the primary belt pulley 32 and the secondary belt pulley 41, a bearing is arranged on the bearing plate 24, the right end of the rotating shaft 4 is connected with the bearing in the bearing plate 24, a waist-shaped hole is vertically arranged on the bearing plate 24, connecting bolts pass through the waist-shaped hole and are threadedly connected with the right side wall of the fixed frame 21, three second check nuts 212 are threadedly connected with the fixed frame 21, the three second check nuts 212 all abut against the top wall of the bearing plate 24 vertically, a shoulder 42 and an external thread 43 are arranged on the rotating shaft 4 between the bearing seat 23 and the bearing plate 24, a plurality of partitions 44 are arranged at intervals on the rotating shaft 4, one impeller 6 is clamped between every two partitions 44, the partition 44 close to the shoulder 42 abuts against the shoulder 42, three abutting nuts 45 are threadedly connected with the external thread 43, one of the three abutting nuts 45 is screwed against the partition 44 on the same side, the three abutting nuts 45 are screwed against each other, the abutting nuts 45 cooperate with the shoulder 42 to lock and fix the partitions 44 and the impeller 6, the tightening directions of the three abutting nuts 45 are the same as the rotating direction of the rotating shaft 4 driven by the speed reducer 3, when the rotating shaft 4 rotates, the abutting nuts 45 will only be screwed tighter, thereby increasing the locking force on the impeller 6 and the partitions 44.

[0019] In use, the metal plate is placed on the support table 12 of the numerical control gantry 1, then the speed reducer 3 is started to drive the rotating shaft 4 to rotate through the transmission belt 5, the rotating shaft 4 drives the impeller 6 to rotate, then the ram 11 on the numerical control gantry 1 is controlled to move downward along the Z axis, so that the rotating impeller 6 contacts the metal plate, then the support table 12 is controlled to move forward and backward along the X axis direction, so that the impeller 6 can polish the surface of the metal plate, after the impeller 6 is separated from the metal plate, the ram 11 on the numerical control gantry 1 is controlled to move left and right along the Y axis direction, and the support table 12 is reset along the X axis direction, so that the impeller 6 can polish the part not polished, the metal impurities accumulated on the metal plate polished by the impeller 6 are removed, the surface of the metal plate no longer has protruding metal impurities, then the polished metal plate is conveyed to the milling machine to perform milling work, and the milling cutter will not be broken in the milling process.

[0020] When the transmission belt 5 needs to be replaced, loosen the four motor bolts 31 on the reduction motor 3, the positioning plate 222 is no longer tightly against the n-shaped support plate 22, loosen the first adjusting bolt 224 and the second adjusting bolt 226, adjust the position of the reduction motor 3, move the reduction motor 3 towards the rotating shaft 4 to shorten the distance between the main pulley 32 and the secondary pulley 41, which is convenient for removing the failed transmission belt 5 and installing a new transmission belt 5, after the transmission belt 5 is replaced, move the reduction motor 3 away from the rotating shaft 4 to increase the distance between the main pulley 32 and the secondary pulley 41, tension the transmission belt 5, first tighten the first adjusting bolt 224 and the second adjusting bolt 226, then tighten the four motor bolts 31 on the reduction motor 3, so that the positioning plate 222 tightly abuts against the n-shaped support plate 22, thereby fixing the reduction motor 3, when the reduction motor 3 drives the rotating shaft 4 through the transmission belt 5, the reduction motor 3 and the rotating shaft 4 will be subjected to tension, and because the n-shaped support plate 22 on the left side is close to the main pulley 32, and the first adjusting bolt 224 on the n-shaped support plate 22 pushes the reduction motor 3 forward, the first adjusting bolt 224 can prevent the end of the reduction motor 3 close to the main pulley 32 from moving backward after being subjected to tension, but after being limited by the first adjusting bolt 224, the reduction motor 3 is prone to rotate forward with the first adjusting bolt 224 as the center and away from the main pulley 32, at this time, the n-shaped support plate 22 on the right side is away from the main pulley 32, and the second adjusting bolt 226 on the n-shaped support plate 22 pushes the reduction motor 3 backward, the first adjusting bolt 224 cooperates with the second adjusting bolt 226 to limit the reduction motor 3.

[0021] When the rotating shaft 4 is subjected to tension from the transmission belt 5 and resistance from the centrifugal wheel 6 during polishing, it will exert a large reaction force on the bearing seat 23 and the bearing plate 24, which is prone to cause the bearing seat 23 to loosen and cause the rotating shaft 4 to jam, the bearing seat 23 is fixed on the bottom wall of the fixed frame 21 by bolts, and is limited by the four first locking bolts 211 to prevent loosening, and the bearing plate 24 can adjust the up-down position of the bearing plate 24 through the waist-shaped hole, so that the bearing on the bearing plate 24 is coaxially aligned with the bearing in the bearing seat 23, when replacing the centrifugal wheel 6, the bearing plate 24 is disassembled and the abutting nut 45 is unscrewed to quickly replace the centrifugal wheel 6, when the bearing plate 24 is reinstalled on the fixed frame 21, the bearing on the bearing plate 24 is coaxially aligned with the rotating shaft 4 through the waist-shaped hole, which facilitates the connection of the rotating shaft 4 and the bearing in the bearing plate 24, and the bearing plate 24 is limited by the three second locking bolts 212 and the connecting bolts to limit the bearing plate 24, thereby ensuring the smooth rotation of the rotating shaft 4.

[0022] It should be explained finally: the above examples are only used to illustrate the technical scheme of the utility model and not to limit it, although the utility model has been explained in detail with reference to the above examples, the ordinary skilled in the art should understand that: the specific implementation of the utility model can still be modified or replaced, and any modification or equivalent replacement without departing from the spirit and scope of the utility model should be covered in the protection scope of the claims of the utility model.
