Abstract
Provided is a hole boring cutter. The hole boring cutter comprises a drilling head. The drilling head is arranged at the front end of a rotating shaft in an inserting mode and fixed by drilling head fixing screws, and a connector is machined at the back end of the rotating shaft. A step-shaped shaft body is machined in the middle of the rotating shaft, a boring cutter installation hole is machined in each step, and one boring cutter is installed in each boring cutter installation hole. Grooves are machined in the outer surface, corresponding to installation holes, of the shaft body, and boring cutter fixing screws are installed in the grooves. By adopting the hole boring cutter, after cutters are installed at a time, users can drill holes in work-pieces, boring cutters arranged on the step-shaped shaft body of the rotating shaft can carry out reaming processing on the same round hole for a plurality of times, and production efficiency is improved greatly.
Description
Technical field
The utility model belongs to the machining tool technical field, relates to a kind of hole boring cutter that is installed on the boring machine.
Background technology
In the prior art, simple in structure at the borer that workpiece is holed, mainly formed by a drill bit and brill body, the effect of drill bit is upper boring, the effect of boring body is to enlarge the aperture.The borer of this structure, when carrying out Boring, to hole first, enlarge again the processing in aperture, need when enlarging the aperture constantly to change the larger process tool of diameter, make the processing aperture constantly increase this processing mode, need to expend a large amount of time and carry out the replacing of cutter, production efficiency is very low.
The utility model content
The utility model is in the prior art, borer is simple in structure, need to change repeatedly the problem that cutter just can process major diameter round hole, a kind of hole boring cutter is provided, this cutter includes a drill bit, drill bit is inserted into the front end of rotating shaft, fix with the drill bit hold-down screw, the rear end of rotating shaft is processed with connector, is processed with the axle body of step at the middle part of rotating shaft, is processed with respectively the boring cutter installing hole on each step, hole boring cutter is installed in the hole, axle body outer surface corresponding with installing hole is processed with groove, and the boring cutter hold-down screw is installed in the groove.
After adopting technical solutions of the utility model, behind the disposable mounting cutter, can hole at workpiece, the boring cutter that is positioned on the rotating shaft step axle body can carry out repeatedly reaming processing to same circular hole, and production efficiency improves greatly.
Description of drawings
Fig. 1 is structural representation of the present utility model.
