The bearing seat 49 is threadedly connected to the retaining frame 33 through bolts. Specifically, the retaining frame 33 is provided with a rectangular groove for the drilling rod 48 to move and multiple threaded holes adapted to the bolts. When the position of the drilling rod 48 needs to be adjusted, the bolts on the bearing seat 49 are removed and the bearing seat 49 can be fixed by threading it with different threaded holes on the retaining frame 33.

[0057] Both the rotating shaft 37 and the opening shaft 42 are provided with strip grooves, and the inner walls of the bevel gear 43 and the curved plate bracket 38 are provided with splines adapted to the strip grooves. The extension shaft 45 is rotatably matched with the retaining frame 33 through the bearing.

The clamping arm 59 rotates with the plate clamping block 55. A clearance groove is provided on the push frame 57. When the push frame 57 moves, the connecting rod 58 can move in the push frame 57 to ensure the effective drive of the clamping arm 59.

The electric push rod 39 can be retracted to drive the clamping plate 35 to cooperate with the curved plate clamping frame 38 to clamp and fix the curved plate. The curved plate that meets the quality inspection requirements can be opened. The opening motor 41 drives the opening shaft 42 to drive the bevel gear 1 43 to engage the bevel gear 2 44. The bevel gear 2 44 drives the extension shaft 45 to drive the bevel gear 3 46, thereby engaging the bevel gear 47. The bevel gear 47 can drive the opening drill rod 48 to drive the opening drill to punch. After punching, the rotating motor 36 drives the rotating shaft 37 to drive the curved plate clamping frame 38 to rotate and punch holes in different positions. For different curved plates, the position of the curved plate clamping frame 38 can also be adjusted to suit curved plates of different lengths.
