The utility model discloses increase chamfer sword, reamer and divided multistagely on the reamer basis, can once accomplish the work of rough machining, chamfer, fraising, simplified the production procedure, improved work efficiency, ensured the machining precision.
Description
Technical field
The utility model relates to machining tool field, is exactly specifically a kind of special reamer of hole machined.
Background technology
In mechanical processing process, often need to carry out fraising in the mechanical processing process of especially cast member to process, example is processed as with the fraising of the box-type workpieces of aluminium alloy high pressure casting, the process in existing this hole is first roughing hole, aft-loaded airfoil spot face, chamfering, then the processing mode reamed.Use much knives tool, process needs tool changing, loses time, adds cost, is also unfavorable for the guarantee of machining accuracy.
For above problem, be necessary to provide a kind of special reamer that once can complete roughing, chamfering, fraising work.
Summary of the invention
The utility model is in order to provide a kind of special reamer, and this special reamer adds rose reamer on reamer basis, reamer divides multistage, once can complete the work of roughing, chamfering, fraising, simplify production procedure, improve operating efficiency, ensure machining accuracy.
The technical scheme in the invention for solving the technical problem is: a kind of special reamer, comprise reamer blade 1, chamfering blade 2, cutter hub 3, cutter hub 3 by afterbody to front end descending setting at least two steps, stepped diameters the closer to cutter hub 3 afterbody is larger, cutter hub 3 step is foremost provided with reamer blade 1, the step of the most afterbody of cutter hub 3 is provided with chamfering blade 2, the step of cutter hub 3 foremost between step and most afterbody step is provided with reamer blade 1 or chamfering blade 2; Cutter hub 3 afterbody center is also provided with inner cold water hole 4, and inner cold water hole 4 is communicated with reamer blade 1, chamfering blade 2.
As optimization, described cutter hub 3 afterbody is also provided with handle of a knife 5, and cutter hub 3 afterbody center is provided with locating hole, handle of a knife 5 is provided with the locating dowel corresponding with cutter hub 3 afterbody locating hole.
As optimization, described handle of a knife 5 center is provided with the through hole corresponding with inner cold water hole 4.
As optimization, described cutter hub 3 front end face center is also provided with detection ring 6.
As optimization, described reamer blade 1, chamfering blade 2 are embedded in cutter hub 3.
The beneficial effects of the utility model are: compared with prior art, the utility model adds rose reamer on reamer basis, reamer divides multistage, once can complete the work of roughing, chamfering, fraising, simplify production procedure, improve operating efficiency, ensure machining accuracy.
