Special steel pipe rod drilling device

The utility model relates to the technical field of industrial machinery manufacturing, in particular to a special steel pipe rod drilling device, which can overcome the defects in steel pipe rod drilling that drill holes cannot be positioned accurately, the centers of the drill holes can be easily deviated from the central position, the efficiency is low and the cost is high. The special steel pipe rod drilling device comprises a base, a running wheel is arranged on the base, and the two ends and the middle part of the base are respectively provided with three groups of positioning clamps with the same shape, so that a work piece can be fixed. The special steel pipe rod drilling device also comprises a set of drill mold, and drilling sleeves are arranged at different positions for different work pieces and can be replaced according to the diameters of the drill holes. The drilling mold is fixed on the work pieces through a limiting plate, so that the accurate and rapid mechanical drilling can be realized. By adopting the technology, the defects that the drill holes cannot be positioned accurately and the centers of the drill holes can be easily deviated from the central position can be overcome, the efficiency can be increased, and the cost can be reduced.
