The invention provides automatic drilling equipment for machining. The automatic drilling equipment for machining mainly comprises a penetrated hole, a drilling machine, a descending motor switch, a downward pressing column, a control motor, a control transmission shaft and a clamping part. The middle position of a bearing plate is penetrated through by the drilling machine. The bearing plate is fixedly connected with the drilling machine. The bottom of the control motor is mounted on the upper side edge of the bearing plate in a welded mode. The control motor is connected with the middle position of the rear side of the clamping part through the control transmission shaft. A descending motor and a descending gear rotate to enable the descending motor, a bearing rod and the whole bearing plate to move downwards and enable the drilling machine to conduct drilling on a material on the base. When drilling operation is completed, the clamping part just rotates to an arc-shaped notch to switch off the descending motor switch to make the descending motor stop operating, and the bearing rod are jacked up by internal springs through sliding heads at the two ends. Through the arrangement, the drilling machine is made to descend intermittently to conduct drilling operation on the material.
