The three-phase asynchronous motor front end cover drilling tool comprises a workbench and a placing plate, the placing plate is fixedly connected to the top of the workbench, a connecting assembly is arranged on the outer wall of the placing plate, a clamping assembly is arranged on the outer wall of the placing plate, and the connecting assembly is composed of a limiting unit and a fixing unit. According to the device, by arranging an extension column and a threaded column, after a movable plate is fixed, a drilling plate can be moved in a sliding mode, so that the drilling plate drives the extension column to slide in the movable plate and a placement plate, and a semicircular rod mounted on the outer wall of the extension column can achieve a limiting effect on the extension column; and a motor is started, the motor drives a threaded column to rotate through an output shaft, due to the fact that the outer wall of the threaded column is matched with the inner wall of the extending column, when the threaded
