An object of the utility model is to overcome the aforesaid not enough, provide a simple structure, the clamping is convenient, can prevent that the flange from taking place the frock for the drilling of major diameter thin wall flange that warp when major diameter thin wall flange drills to ensure drilling position precision and straightness that hangs down, improve the lumber recovery and the qualification rate of major diameter thin wall flange, reduce the drilling machine trouble.
The purpose of the utility model is realized like this:
a tool for drilling a large-diameter thin-wall flange comprises a circular base, wherein a plurality of annular steps taking the center of a circle of the base as the center are arranged on the top surface of the base; the heights of the top surfaces of the annular steps are all lower than that of the top surface of the base; a raised ring is arranged between the annular step at the outermost ring and the adjacent annular step at the inner ring; a plurality of through holes are uniformly distributed on each annular step; and a plurality of groups of pressing devices are also arranged on the top surface of the base.
Further, the height of the top surface of the annular step is gradually increased from the inner ring to the outer ring.
Furthermore, the annular step is also provided with bolt holes.
Furthermore, the pressing device comprises a bottom plate arranged on the top surface of the base, a cylinder vertically and fixedly arranged on the bottom plate, a cross rod arranged at the top of the movable end of the cylinder, and a pressing rod arranged at the free end of the cross rod.
Compared with the prior art, the beneficial effects of the utility model are that:
the annular step supporting surface is arranged at the bottom of the large-diameter thin-wall flange, so that annular plane support is provided for the flange, deformation which is easy to generate when the flange is subjected to drilling pressure is prevented, the verticality of a drilled bolt hole is ensured, and the condition that a drill bit is broken is reduced; the flange is quickly positioned by utilizing the height difference of the annular step and the raised ring, so that the clamping efficiency of the flange is improved; utilize bolt hole and closing device to compress tightly fixedly to the flange, prevent its offset, improve drilling position precision.
