The invention relates to the technical field of bearing machining, in particular to bearing inner ring threaded hole automatic machining equipment. The bearing inner ring threaded hole automatic machining equipment comprises a charging device and a rotary plate. A plurality of positioning tools are arranged at the top of the rotary plate. The discharging end of the charging device is connected andmatched with one of the positioning tools. A first drilling device, a second drilling device and a center rotary table are further arranged on the side of the rotary plate. The first drilling deviceand the second drilling device are distributed on the side of the rotary plate with the included angle between the first drilling device and the second drilling device being 120 degrees. A rotary positioning device arranged vertically is arranged in the center of the center rotary table. A tapping device, a deburring device and a detection device are sequentially arranged in the circumferential direction of the rotary positioning device. A first conveying belt is arranged on the side of the center rotary table. A transfer mechanism is arranged between the rotary plate and the center rotary table. The charging, drilling, tapping, deburring, detecting and discharging operation of workpieces can be achieved automatically, the number of operators and labor force are greatly reduced, the production efficiency is improved, and the machining cost is low.
