Abstracts: Productivity of Square holes drilling machine is changed by anything that affects the design and mechanism of machine working. Setting up process of Square holes is very time consuming process if right mechanism and technology is not utilized. Typically, the proper equipment and manufacturing technology is determined based on the organization budgets and their requirements. Usually machines have The utility model relates to a square tube drilling machine which comprises a pedestal, a transmission mechanism, an upright post, a cross beam and drill bits, wherein, one end part of the upright post is fixed on the pedestal, the cross beam is fixed at the other end part of the upright post, the drill bits are arranged on the cross beam and can perform processing of a square tube on the transmission mechanism, a plurality of drill bits are arranged along the extension direction of the square tube and are connected to a sliding bracket, and the sliding bracket is correspondingly arranged on the upright post in a sliding way; and a cutting end face of a drill bit main body of each drill bit corresponding to the square tube is provided with an annular groove which takes the axial line of the drill bit as the axial line, so as to enable the centre of the cutting end face to form a convex part ridging outwards along the axial line of the drill bit. The square tube drilling machine adopting the proposals not only can complete the processing of a plurality of holes on one square tube simultaneously, but also can drill in one step and does not need drill positioning holes in advance, thereby reducing the procedure, shortening the labor hour and enhancing the drilling efficiency.
