The invention provides an automatic processing machine for a bearing inner ring screw hole. The automatic processing machine comprises an engine base and a turntable, wherein the turntable can rotate in an indexing intermittent mode under the action of a power transmission device; the periphery of the turntable is uniformly provided with clamps for clamping workpieces; drilling devices, tapping devices, hole detection devices, burr filing devices and feeding and discharging mechanical arms are arranged around the turntable; all the devices are corresponding to positions where the clamps on the turntable stay; the hole detection devices are arranged on the downstream sides of the drilling devices and tapping devices; the burr filing devices operate after the completion of screw hole detection; the feeding and discharging mechanical arms are respectively linked with a feeding device and a discharging device. By adopting the automatic processing machine, feeding, drilling, tapping, burr removing, and discharging can be automatically realized, and only one operator is needed for carrying out management and monitoring; the labor intensity is greatly reduced, the production efficiency is high, the processing cost is low, and the product quality is stable.
