Abstract

The utility model discloses a taper reamer with unequal teeth. Cutter teeth (1) are the unequal teeth, and a cutter groove (2) has slope. The taper reamer with the unequal teeth has the advantages that with the adoption of the unequal teeth, the cutting resistance is reduced, the cutting is light and quick, the cutting speed is improved, the resonance problem of a cutter during high-speed large-feeding cutting can be changed meanwhile, the degree of finish of the surface is improved, the cutter is lighter and quicker during cutting, the processing quality of the surface of a workpiece is improved, the regrinding times of the cutter are more, the durability of the cutter is improved, the service life of the cutter is prolonged and the production efficiency is improved.

Description

Do not wait tooth tapering reamer
Technical field
The utility model relates to the combined type taper reamer in the taper hole process tool, does not particularly wait tooth tapering reamer.
Background technology
Processing taper hole taper reamer generally commonly used or extruding cutter are finished, reach certain fineness after so just requiring taper hole to machine, add man-hour at taper hole, for working (machining) efficiency is improved, have only and consider to improve its process velocity, the rotating speed and the tool feeding that comprise cutter, and common taper reamer can make taper hole fineness significantly reduce when the high speed roughing feed.Adopt traditional tapering reamer, its slot form and the degree of depth are identical on same cylindrical, each cutter tooth cutting output and cutting speed all along is all identical, work in-process is because each toe joint of workpiece and cutting teeth touches all identical like this, be easy to generate resonance when making cutting, cutting resistance increases, and causes cutting surface of poor quality, even produces the shake line in High-speed machining.
The utility model content
The purpose of this utility model promptly is to overcome the shortcoming of prior art, provide a kind of can improve processing taper hole surface quality does not wait tooth tapering reamer, it can be enhanced productivity, raising durability, and be suitable for High-speed machining.
The purpose of this utility model is achieved through the following technical solutions: do not wait tooth tapering reamer, cutter tooth adopts not five equilibrium tooth, and cutter slot has gradient.
The five equilibrium cutter tooth does not have six on circumference, and five equilibrium cutter tooth profile angle is not respectively θ 1, θ 2, θ 3, θ 4, θ 5, θ 6,4=60 ° of 50' of θ 1=θ wherein, and θ 2=θ 5=61 ° 40 ', and θ 3=θ 6=57 ° 30 '.
The angle of inclination of cutter slot is α, and α is 0.5~3 °.
By top narration as can be seen, the utlity model has following advantage: adopt not that the five equilibrium cutter tooth reduces cutting resistance, cut briskly, cutting speed improves, and can change cutter simultaneously and produce resonance when the high speed roughing feed cuts, and has improved surface smoothness; Band gradient cutter slot continues to increase tool orthogonal rake from front to back, makes cutter influence Tool in Cutting when chipping allowance changes and drop to minimumly that cutter is more brisk during cutting; Cutter tooth land and cutter core are thick to be strengthened and suitably strengthens with the tapering cylindrical, make and also strengthened cutter tooth intensity and cutter bulk strength when strengthening chip space, make chip removal smooth and easy, iron filings are difficult for squeezing hinders and wounded manufactured taper hole surface, cutting fluid also can flow into smoothly, fully play lubricated and cooling effect, thereby improved the crudy of surface of the work.This cutter is owing to adopt not five equilibrium helical teeth cutting, cutter regrinding and common taper reamer are basic identical, more after the cutter structure adjustment than universal cutter regrinding number of times, the durability of cutter is improved, prolong cutter life, the corresponding reduction of cutter production cost, and the speed of processing work improves, production time per piece reduces, and production efficiency is improved.
Description of drawings
Fig. 1 is the utility model structure chart
Fig. 2 is that the utility model K is to end view
Among the figure, 1-cutter tooth, 2-cutter slot.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but protection domain is not limited to the following stated.
As Fig. 1, Fig. 2, do not wait tooth tapering reamer, cutter tooth 1 adopts not five equilibrium tooth, five equilibrium cutter tooth 1 does not have six on circumference, and five equilibrium cutter tooth 1 profile angle is not respectively θ 1, θ 2, θ 3, θ 4, θ 5, θ 6, wherein 4=60 ° of 50' of θ 1=θ, θ 2=θ 5=61 ° 40 ', and θ 3=θ 6=57 ° 30 '.The five equilibrium tooth does not make cutter when the high speed roughing feed cuts, and makes the per tooth cutting output inconsistent, has higher stability, does not produce resonance in process, has improved the taper hole surface smoothness.
Cutter slot 2 has gradient, and the angle of inclination of cutter slot 2 is α, and α is 0.5~3 °.α gradient groove continues to increase tool orthogonal rake from front to back, groove and land also constantly increase, when cutting, has very high stability, make that influence drops to minimum cutter to Tool in Cutting when chipping allowance changes, cutter is more brisk during cutting, and chip pocket can adopt straight trough or helicla flute, when cutter when the high speed roughing feed cuts, because do not wait the tooth reamer to be difficult for producing the shake line, the quality that product is caused because of taper hole fineness is relatively poor descends even becomes waste product and is well controlled.

Claims (3)

1. do not wait tooth tapering reamer, it is characterized in that: cutter tooth (1) adopts not five equilibrium tooth, and cutter slot (2) has gradient.
2. the tooth tapering reamer that do not wait according to claim 1, it is characterized in that: five equilibrium cutter tooth (1) does not have six on circumference, five equilibrium cutter tooth (1) profile angle is not respectively θ 1, θ 2, θ 3, θ 4, θ 5, θ 6,4=60 ° of 50' of θ 1=θ wherein, θ 2=θ 5=61 ° 40 ', and θ 3=θ 6=57 ° 30 '.
3. the tooth tapering reamer that do not wait according to claim 1, it is characterized in that: the angle of inclination of cutter slot (2) is α, α is 0.5~3 °.
