Nut drilling equipment

The invention discloses nut drilling equipment which comprises a machining table, a vertical sliding groove is formed in the machining table, a mounting base is slidably mounted in the sliding groove and can move up and down in the sliding groove, a nut body is placed on the mounting base, and a drilling station, an adjusting station and a discharging station are sequentially arranged on the machining table from top to bottom. A support is mounted on the upper surface of the machining table, a lifting air cylinder is mounted on the support, a pressing cover is arranged at the output end of the lifting air cylinder, a discharging through groove is formed in the mounting base, a waste pipe is connected to the bottom of the discharging through groove, and a waste collecting box is connected to the waste pipe. The drilling station is arranged in the sliding groove, so that the drilling station is prevented from being exposed in the external environment, and splashing of sweeps is reduced; during drilling, a nut i
