The casting 5 to be polished is placed in the placement space, and the protruding part on the casting 5 is engaged with the limiting post 12, thereby fixing the casting 5 and preventing the casting from shifting horizontally when the rotating base plate 2 rotates, so as to ensure the polishing effect.

[0026] Furthermore, such as Figures 1 to 3 As shown, a first guide rail 6 and a second guide rail 7 are vertically and spaced apart on the base plate 1. The slider 8 slides along the length of the first guide rail 6 and the second guide rail 7. A nozzle reinforcement bracket 13 is vertically connected to the slider 8. A nozzle connector 14 is vertically connected to the end of the nozzle reinforcement bracket 13 away from the slider 8, so that the curved nozzle 11 of the sandblasting machine connected to the nozzle connector 14 can move in the vertical direction. A first lock 9 is provided on the second guide rail 7, and a second lock 10 is provided on the slider 8. The slider 8 moves in the vertical direction to engage the second lock 10 with the first lock 9, so that the curved nozzle 11 of the sandblasting machine is aligned with the position to be polished in the inner cavity of the casting 5.

[0027] In this embodiment, preferably, a first guide rail 6 and a second guide rail 7 are vertically welded on the base plate 1. The first guide rail 6 and the second guide rail 7 are spaced apart, and the distance between the first guide rail 6 and the second guide rail 7 and the rotating base plate 2 is equal. Two through holes are opened at intervals on the slider 8. The slider 8 is inserted into the first guide rail 6 and the second guide rail 7 through the through holes, so that the slider 8 slides up and down along the length direction of the first guide rail 6 and the second guide rail 7.

[0028] A nozzle reinforcement bracket 13 is vertically welded at the middle position of the slider 8. A nozzle connector 14 is vertically welded at the end of the nozzle reinforcement bracket 13 away from the slider 8.
