The reamer has the advantages of durability, reducing the consumption cost of the cutter and being suitable for processing high-precision holes.
Description
Technical field
The utility model relates to a kind of reamer, specifically is used for the reamer in machining high-precision hole, especially processes the reamer in the higher hole of required precision, aperture.
Background technology
At present, often there is the hole processing of various high-precision requirement in the mechanical part processing.Because design level is more and more higher at present, and is also more and more higher to the requirement of processing parts, so in machining, often run into the processing in the hole that the degree of precision requirement is arranged.But because the having relatively high expectations of aperture, the hole tolerance that has requires to have only 0.01mm, and is that have even also littler, all is to adopt boring earlier usually, and reaming is again finish reamed then, reaching high-precision requirement, yet the problem of tool life occurred like this.For the processing in the high hole of required precision, the method that adopts usually is at present: use the bit drills bottom outlet earlier, with cornish bit appropriate size is expanded in the aperture again, stay suitable surplus for finish reaming, and then finish ream the hole to reach the part processing requirement.But, because the hole tolerance of workpiece is little, the rated wear of cutter is just littler, so cutter may wear to lower limit soon, the durability of cutter has become subject matter, or is that tapering appears in machining hole, is forced to change cutter, increase the consumed cost of cutter greatly, caused production cost to improve greatly.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, a kind of durable is provided, reduce cutter consumed cost, be suitable for the reamer of high accurate hole processing.
For solving the problems of the technologies described above, the utility model provides a kind of high accurate hole processing reamer, comprise cutter hub, be welded with the multiple-cutting-edge reamer head of a plurality of carbide chips in the end of described cutter hub, also comprise cone screw, offer the conical bolt hole that matches with described cone screw at described cutter hub with the end that multiple-cutting-edge reamer head is connected a side, described cone screw is threaded with described conical bolt hole.
Described cutter hub and described cone screw adopt slightly elastic 9SiCr alloy material.
Described cone screw end face diameter size D1=(0.4-0.6) D, wherein D represents to be welded with on the cutter hub diameter of the first side end of multiple-cutting-edge reamer.
The tapering of described cone screw is 1: 16.The tapering of described conical bolt hole also is 1: 16, and the aperture size is (0.4-0.6) D, and wherein D represents to be welded with on the cutter hub diameter of the first side end of multiple-cutting-edge reamer.
The L2 of described cone screw length L=(2.5-3), wherein L2 represents the axial length of multiple-cutting-edge reamer head, the reach of described cone screw is 0.5L.Described cone screw end face offers interior hex slot.
The utility model partly adopts the cone screw that plays corrective action of band taper at cutter head, by adjusting the precession amount of cone screw in conical bolt hole, makes the stressed expansion of cutter hub, is interference fit between cone screw and conical bolt hole.The small increase of the diameter of adjustable reamer head has improved the durability of cutter significantly in the processing of high-precision hole.Owing to adopt technique scheme, the utlity model has following beneficial effect: solved common reamer because of the little few problem of cutter allowance that causes of machining hole tolerance is arranged, be not only applicable to the processing in the hole of common requirement, and be more suitable in the processing in the high hole of required precision, and can guarantee size accuracy, the linearity requirement of machining hole, and can reduce the consumed cost of cutter.
Description of drawings
Fig. 1 is the structure chart of the utility model high accurate hole processing with reamer.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-cutter hub; 2-multiple-cutting-edge reamer head; The 3-cone screw; Hex slot in the 4-.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment is illustrated:
As shown in Figure 1, the utility model high accurate hole processing reamer, comprise cutter hub 1, be welded with the multiple-cutting-edge reamer head 2 of a plurality of carbide chips in the end of cutter hub 1, also comprise cone screw 3, offer the conical bolt hole that matches with cone screw 3 at cutter hub 1 with the end that multiple-cutting-edge reamer head 2 is connected a side, cone screw 3 is threaded with conical bolt hole.Wherein, cutter hub 1 and cone screw 3 adopt slightly elastic 9SiCr alloy material.
Cone screw 3 end face diameters size D1=(0.4-0.6) D, wherein D represents to be welded with on the cutter hub diameter of multiple-cutting-edge reamer head 2 one side ends.
Preferably, the tapering of cone screw 3 is 1: 16.The tapering of conical bolt hole also is 1: 16, and its aperture size is (0.4-0.6) D, and wherein D represents to be welded with on the cutter hub diameter of multiple-cutting-edge reamer head 2 one side ends.
The L2 of cone screw length L=(2.5-3), wherein L2 represents the axial length of multiple-cutting-edge reamer head, the reach of described cone screw is 0.5L.
The utility model partly adopts the cone screw 3 that plays corrective action of band taper at cutter head, by adjusting the precession amount of cone screw 3 in conical bolt hole, make cutter hub 1 stressed expansion, the small increase of the diameter of adjustable reamer head 2 has improved the durability of cutter significantly in the processing of high-precision hole.
The utility model adopts welded type multiple-cutting-edge reamer head 2, and alloy blade is welded direct on the cutter hub 1, and cutter hub 1 end face has a conical surface hole that cooperates with cone screw 3, i.e. conical bolt hole, and have the fine thread that mates with cone screw in inside.The cone screw end face offers interior hex slot 4, so that adjust cone screw 3 with inner hexagon spanner, and then adjusts multiple-cutting-edge reamer head 2 diameter.Before grinding reamer head diameter, guarantee closely cooperating of cone screw and knife bar earlier, grind reamer head diameter with grinding machine again, the band cooling grinds, and it is ordinary skill in the art means that grinding method adopts.
