The utility model discloses a drilling and tapping device which comprises a machine base, a fixing plate is fixed to the bottom of the machine frame, a plurality of fixing bases are detachably fixed to the upper surface of the fixing plate and located in the machine frame, tapping drill bits are arranged at one ends of the fixing bases and located below the fixing plate, and a driving mechanism is arranged in a driving box. And a transmission mechanism is arranged between the driving mechanism and the tapping drill bit. According to the drilling and tapping device, the connecting ring is changed into the short fixing base, the fixing base is fixed through the fixing plate, and the distance between the tapping drill bit and the fixing position of the fixing base can be kept unchanged, so that the length of a load arm of the fixing base is kept unchanged; and the fixed seat and the tapping drill bit are limited through the positioning cylinder, so that the influence of vibration generated by the drill bit in wo
