Description
Technical field
The present invention relates to Gear Processing apparatus technical field, particularly to a kind of new gear process tool.
Background technology
Gear Processing process is a profiling process, and tool-tooth profile design is the important foundation of form of gear tooth processing.Gear
Cutter is generally made up of cutter head and cutter root two parts, and cutter head is working portion, and cutter root is inoperative part.Due to form of gear tooth portion
Dividing and directly determined by cutter, the tool bit part structure design of cutter is particularly critical.But existing cutting tool insert part is led to
Often be made up of involute portion, arc sections and line part, however between involute portion and arc sections due to can not rounding off, pole
It is easily formed flex point, causes stress at flex point to be concentrated, be easily generated wedge angle little Yang, cause cutter easily to be formed when heat-treatment quenching and split
Stricture of vagina source, there will be crackle and cracking time serious, and due to the existence of flex point, makes gear tooth surface the roundest and the most smooth projection occur, lead
Cause to there is the problem that serious wear, engagement property difference and transmission are unstable, and existing cutter head arc sections radius is less, causes existence to be cut
Cut the defects such as intensity difference, easy fracture, phenomenon of forging a knife is serious, working (machining) efficiency is low.
Summary of the invention
It is an object of the invention to solve above-mentioned deficiency, it is provided that a kind of new gear process tool, Gear Processing is had
High-quality, high efficiency, low consumed feature.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of new gear process tool, is integrally formed by cutter head and cutter root, and described cutter head is working position, described cutter root
For inoperative position, described cutter head is made up of involute portion, oblique line portion, arc sections and line part, and described oblique line portion is used for transition
Coupling described involute portion and arc sections, the inclined angle alpha angle in described oblique line portion is 3 °-4 °, described arc sections radius of corner chi
Very little scope is at 8mm-12mm, and described line part is positioned at described cutter head top surface.
Preferably, the inclined angle alpha angle in described oblique line portion is 3.5 °, and described arc sections radius of corner size range is at 9mm-
11mm。
Preferably, the material hardness scope of described cutter head is 66.0HRC-67.5HRC.
Preferably, the material hardness scope of described cutter head is 66.5HRC-67HRC.
Preferably, the inclined angle alpha angle in described oblique line portion is 3 ° 9 ' 6 ", described arc sections radius of corner a size of 8.6mm.
Preferably, the inclined angle alpha angle in described oblique line portion is 3 ° 25 ' 54 ", described arc sections radius of corner is a size of
12mm。
The present invention compared with prior art has following outstanding advantages and effect: the present invention is by process tool structure
Optimize design, increase knife tool arc portion radius of corner size, improve intensity and the service life of cutter, involute portion and circle
Use the transition of oblique line portion to couple between arc portion, flex point can be eliminated, it is to avoid cutter stress is concentrated, and solves cutter in Gear Processing
Middle fracture and the problem forged a knife, have high-quality, high efficiency, low consumed feature to Gear Processing.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
In having technology to describe, the required accompanying drawing used is briefly described, it should be apparent that, the accompanying drawing in describing below is only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to
Other accompanying drawing is obtained according to these accompanying drawings.
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
As it is shown in figure 1, a kind of new gear process tool that the present invention provides, cutter head 1 and cutter root 2 are integrally formed, cutter
1 is working position, and cutter root 2 is inoperative position, and the material hardness scope of cutter head 1 is 66.0HRC-67.5HRC, makes cutter head 2
Possessing high rigidity, high-wearing feature, high intensity and high tenacity, cutter head 1 is by involute portion 14, oblique line portion 13, arc sections 12 and straight line
Portion 11 is constituted, and oblique line portion 13 couples involute portion 14 and arc sections 12 for transition, and the inclined angle alpha angle in oblique line portion 13 is 3 °-
4 °, according to involute portion 14 formation basic theory, by changing form of gear tooth coordinate points, utilize oblique line portion 13 by involute portion 14 and circle
Arc portion 12 forms rounding off and couples, it is to avoid the formation of flex point, arc sections 12 radius of corner size range, at 8mm-12mm, adds
Orthodrome portion 12 radius of corner size, improves intensity and the service life of cutter, and line part 11 is positioned at cutter head 1 top surface.
