The invention provides an automatic drilling and tapping integrated machine for standoffs. The automatic drilling and tapping integrated machine for standoffs comprises a workbench, a rotary plate, astepping motor, a feeding mechanism, a drilling mechanism, a tapping mechanism, a material returning mechanism and a positioning mechanism. The stepping motor is fixed to the upper end face of the workbench, the rotary plate is fixed to a main shaft of the stepping motor, and the feeding mechanism, the drilling mechanism, the tapping mechanism and the material returning mechanism are fixed on theupper end face of the workbench and sequentially arranged on the periphery of the rotary plate in the rotating direction of the rotary plate. Jigs distributed at equal angles are arranged on the edgeof the rotary plate, the positioning mechanism is fixed to the upper end face of the workbench and located below the rotary plate, and the positioning mechanism and the rotary plate form positioning fit. The automatic drilling and tapping integrated machine for the standoffs has the beneficial effects that continuous and automatic drilling and tapping operation of the standoffs can be achieved, and automatic production of the standoffs can be achieved by connecting the automatic drilling and tapping integrated machine for the standoffs with other devices in series; and the automatic drilling and tapping integrated machine for the standoffs has the advantages of the simple structure, low manufacturing cost and low maintenance cost.
