The invention relates to the technical field of automatic drilling equipment, and provides automatic drilling equipment for lower bearings. The automatic drilling equipment for the lower bearings comprises an equipment main body, wherein a working table is arranged above the device main body; a fixing device is arranged at the upper end of the working table; a supporting column is arranged on theside, which is close to the fixing device, of the upper end of the working table; a regulation and control rod is arranged at the upper end of the supporting column; a horizontal rod is arranged at one end of the regulation and control rod; a movable shaft is arranged at the front end of the horizontal rod; a protecting shell is arranged at the outer end of a movable shaft at the front end of thehorizontal rod; a connecting block is arranged at the lower end of the movable shaft; and a base plate is arranged at the lower end of the connecting block. By the automatic drilling equipment for lower bearings, it can be ensured that an article cannot shake easily during drilling, drilled holes are standard, the service life of equipment is prolonged, the time for carrying a machined article isshortened, the working efficiency is improved, cooling liquid can further be prevented from flowing to the ground from the equipment, damage of the cooling liquid to the equipment is relieved, the cooling liquid is prevented from flowing to the ground to pollute the environment, and moreover, the cooling liquid can be recycled.
