The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model is when the fuse hole completing workpiece side creeps into, directly drilling tool body can be turned over turnback, the fuse hole of mode of creeping into workpiece opposite side continued along using a fuse hole is processed, and to reduce the error that resetting brings, improves the crudy of workpiece; And the utility model by the positioning and guiding of alignment pin and annular projection to the powerful support of workpiece, workpiece is made to reach correct station when entering locating slot and being inner, solve in prior art need to carry out to rule, milling face, the complicated procedures of forming such as boring, while reducing productive labor intensity, improve production efficiency;
2, the utility model is provided with inclined plane on the both sides outer wall of two elongated ends of the drilling tool body of U-shaped, namely drilling tool body is made to add direct run-off the straight in man-hour, the angle of inclination of drill bushing is reduced, error when reducing the drilling tool difficulty of creeping into as much as possible and creep into, reduces the burr amount in fuse hole;
3, the axis of drill bushing is arranged perpendicular to the inclined plane with drill bushing heteropleural by the utility model, namely make drilling tool body place time, drill bushing directly perpendicular to horizontal plane, when creeping into fuse hole, drilling tool directly realizes vertical processing, maximizes and improves drilling efficiency.
