A differential shell 11 is clamped in the fixture plate 7, and the differential shell 11 overlaps with the positioning structure 8. A motor 13 is connected above the fixture plate 7, and one end of the motor 13 is connected to a grinder 14. The positioning structure 8 includes a clamping block 801, a cooling box 802 and a connecting pipe 803. A telescope 805 is fixedly connected above the cooling box 802, and a flushing pipe 804 is fixedly connected to the top of the connecting pipe 803. A strap 806 is slidably connected to the telescope 805.

[0021] like Figure 1 and Figure 3 As shown, a guide rod 10 is connected to one side of the L-shaped plate 2 6, and the guide rod 10 is rotatably connected to the sleeve plate 2, the clamp plate 7 is connected to the L-shaped plate 2 6, and a hook 12 is connected to the top of the clamp plate 7, the cooling box 802 is fixedly connected to the clamp plate 7, the connecting pipe 803 is connected to the clamp plate 7, the differential housing 11 is clamped in the clamping block 801, the strap 806 is overlapped with the differential housing 11, the cooling box 802 is connected to the connecting pipe 803, and the clamping block 801 is fixedly connected to the top of the clamp plate 7.

[0022] By setting up a cooling box 802, a connecting pipe 803 and a flushing pipe 804, when the fixture plate 7 is flipped to a certain angle, the differential shell 11 in the fixture plate 7 will be processed. During the processing, the flushing liquid in the cooling box 802 will be sprayed on the processing area through the connecting pipe 803 and the flushing pipe 804, so that the connection surface between the grinder 14 and the differential shell 11 can be cooled, and the debris on the surface can be flushed in time.

[0023] like Figure 4 As shown, the collection structure 9 includes a collection box 901 and a fixed column 903.
