[0025] A flipping platform 20; the flipping platform 20 is fixed on the CNC machine table 10;

[0026] A clamping mechanism 30; the clamping mechanism 30 includes a ⊥-shaped boss 31, a lifting drive assembly 32, a pressing plate 33, a rotating platform 35, a rotating drive assembly 36 and a plurality of positioning columns 34. The rotating platform 35 is arranged on the flipping platform 20, and the rotating drive assembly 36 is arranged at the bottom of the flipping platform 20 and its driving part passes through the flipping platform 20 and is connected to the rotating platform 35; the ⊥-shaped boss 31 is arranged on the rotating platform 20, the lifting drive assembly 32 is vertically arranged inside the ⊥-shaped boss 31 and its driving part can lift out of the ⊥-shaped boss 31, the pressing plate 33 is detachably arranged on the driving part of the lifting drive assembly 32 outside the ⊥-shaped boss 31, and a plurality of positioning columns 34 are arranged in a circular array around the ⊥-shaped boss 31 on the rotating platform 35.

[0027] In the specific use process, the tabletop of the flipping platform 20 is first in a horizontal state. The operator inserts the castings of the motor end cover 40 to be processed on the ⊥-shaped boss 31 and makes its ear seat 41 rest on the positioning columns 34. Then, the pressing plate 33 is fixed to the upper end of the driving part of the lifting drive assembly 32. When the lifting drive assembly 32 is driven to drive the pressing plate 33 to lift, the pressing plate 33 will press the entire motor end cover 40 to achieve fixation.

[0028] As known in the art, the flipping platform 20 of the present application includes an active rotating shaft seat 21, a driven rotating shaft seat 22 and a flipping plate 23. The active rotating shaft seat 21 and the driven rotating shaft seat 22 are relatively spaced apart and arranged on the CNC machine table 10. The flipping plate 23 is connected to the rotating shafts of the active rotating shaft seat 21 and the driven rotating shaft seat 22. Under the cooperation of the active rotating shaft seat 21 and the driven rotating shaft seat 22, the flipping plate 23 will be flipped. The purpose of flipping is to make the ear seat 41 in a vertical state so that the drilling equipment can drill at position B.
