The front plate 14 is arranged in front of the two side plates 12 for fixing the guide rail and the slider structure and connecting the reaming structure. The back plate 15 is arranged behind the two side plates 12 for connecting the material protection structure.
[0017] The first transmission mechanism 2 includes a first servo motor 21, a screw rod 22 and a connecting end 23. The first servo motor 21 is fixed on the top plate 13, the screw rod 22 is connected to the bottom of the first servo motor 21, and the end of the screw rod 22 is connected to the connecting end 23. The connecting end 23 is in the shape of a hoop and extends a connecting end, and the connecting end 231 passes through the front plate 14.
[0018] The guide rail 31 is fixed on the front plate 14, and the slider 32 is limited on the guide rail 31. The slider 32 is connected to the connecting end 231 passing through the front plate 14. Driven by the connecting end 23, the slider 32 moves up and down along the guide rail 31.
[0019] The reaming structure 4 is connected to the slider 32 via a support plate 7, and includes a second servo motor 41 and a coupling 42, a reaming shaft 43, a ball bearing 44, a collet 45 and a reamer 46 connected in sequence.
