Abstract
The utility model belongs to the technical field of tool machining, and relates to an anti-vibration reamer. The reamer comprises a handle portion, a neck portion and a reamer head portion arranged at the front end of the handle portion. The reamer head portion is provided with six blades, a cutting edge is arranged at the front end of each blade, chip grooves are formed between the blades, a blade strip is arranged on the front reamer face of each blade, and a 57-degree angle, a 63-degree angle and a 60-degree angle are formed between the adjacent blades in sequence with the center of the reamer head portion as the vertex in the clockwise direction. The reamer is long in service life and high in machining precision, division angles of the cutting edges are changed to be unequal from equal, and therefore fixed frequency of tool vibration is changed, the resonance phenomenon is eliminated, and the roundness precision of a workpiece is improved. Production cost is lowered greatly, and the expected effect can be achieved better.
Description
Technical field
The utility model relates to a kind of vibrationproof reamer, and it belongs to the technical field of tool mechanical processing.
Background technology
Reamer is a kind of in order to excise the rotary cutter of machined surface metal, the hole of cutting after processing through strand can obtain size and dimension accurately, the main effect of its reamer is namely in order to improve the machining accuracy in hole, reduce its surperficial roughness, that its allowance is generally very little for processing and semi-finished cutter.At present, because design level is more and more higher, also more and more higher to the technical requirement of processing parts, the hole of the various high-precision requirement of ubiquity processing in mechanical part processing.
In operating process, reamer all need to just can be rotated processing by being connected on machine tool chief axis, but reamer is all the reamer of Equal in the market, when use because cutter and machine tool chief axis have vibration, again because the blade of reamer is all Equal, so easily form resonance.Blade number is more, and the frequency of resonance is larger, causes the hole circle degree that cuts with scissors out bad, if but reduce sword number, reduce again working (machining) efficiency.
Summary of the invention
For solving the problems of the technologies described above, it is a kind of simple in structure that the utility model provides, and effectively overcomes resonance, carries high-precision vibrationproof reamer.
The utility model solves the technical scheme that prior art problem adopts: a kind of vibrationproof reamer, comprises shank, neck and be located at the cutter head portion of shank forward end.Described cutter head portion is provided with six blades, the front end of every blade offers cutting blade, between every blade, form chip area, the rake face of every blade is provided with land, forms successively in the clockwise direction 57 degree angles, 63 degree angles, 60 degree angles between every adjacent two blades taking described cutter head Bu center as summit.
The width of described cutting blade is 2-10mm.
Beneficial effect of the present invention is: this reamer comprises shank, neck and is located at the cutter head portion of shank forward end.Cutter head portion is provided with six blades, the front end of every blade offers cutting blade, between every blade, form chip area, the rake face of every blade is provided with land, forms successively in the clockwise direction 57 degree angles, 63 degree angles, 60 degree angles between every adjacent two blades taking described cutter head Bu center as summit.This reamer long service life, machining accuracy is high, and the angle of cutting apart of cutting edge is become to not decile from decile, has so just changed the intrinsic frequency of vibration cutting, eliminates covibration, has improved the circularity precision of workpiece.Significantly reduce production cost, and can better produce a desired effect.
