Motor-driven lifting vertical drill with main spindle box fixed on working table

The utility model relates to a motor-driven lifting vertical drill with a main spindle box fixed on a working table, which belongs to the operation and transportation class. The vertical drill comprises a working table, a main spindle box, a column and a motor. The utility model is characterized in that the column is fixed on the working table, and the main spindle box is installed on a column guide rail; a motor-driven lifting mechanism is installed in the main spindle box or on the column; fritter-containing grooves are arranged on both sides of the working table, and each fritter-containing groove presents a 5-20 DEG included angle with the horizontal direction. Because the utility model causes the working table to be fixedly connected with the column, the integral rigidity of the vertical drill can be increased; the fritter-containing grooves with large inclination angles on both sides of the working table is convenient for discharging the fritter and the cooling liquid; the main spindle box is lifted in a motor-driven way to cause the operation to be convenient, and the whole body of the vertical drill is convenient for modular design.
