Description
Technical field
The utility model is related to tap technology field, more particularly to a kind of not equal portions screw tap.
Background technology
Screw tap be processing cylinder and conical internal threads conventional tool, be processing it is various in, small size internal thread
Cutter, it is simple in construction, easy to use, both manually actuated, can also be worked on lathe, applies in production very wide
It is general.Screw tap general at present shakes greatly in the course of the work, so as to influence the precision of a tooth.
Utility model content
The purpose of this utility model is to provide a kind of not equal portions screw tap in view of the shortcomings of the prior art, the not equal portions silk
Cone is novel in design, simple in construction, shakes small, precision height.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions.
A kind of not equal portions screw tap, includes handle of a knife, handle of a knife one end is connected with conehead by cylinder, and conehead upper end is provided with
The unequal a of angle one, the a1 of angle two and folder are provided between three end swords and corresponding and spiral side tool sword, end sword
Spiral helicine chip area is formed between the a2 of angle three, side tool sword, chip area extends to cylinder upper end.
Wherein, a of angle one between the end sword is 115 °.
Wherein, the a1 of angle two between the end sword is 120 °.
Wherein, the a2 of angle three between the end sword is 125 °.
The beneficial effects of the utility model are：A kind of not equal portions screw tap described in the utility model, includes handle of a knife, handle of a knife
One end is connected with conehead by cylinder, and conehead upper end is provided with three end swords and corresponding and spiral side tool sword, end
It is provided between sword between the unequal a of angle one, the a1 of angle two and the a2 of angle three, side tool sword and forms spiral helicine chip area,
Chip area extends to cylinder upper end.The utility model has novel in design, simple in construction, small, the high advantage of precision of vibrations.
Brief description of the drawings
The utility model is further detailed below with accompanying drawing, but the embodiment in accompanying drawing is not constituted pair
Any limitation of the present utility model.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model conehead.
Include in Fig. 1-2：
1 --- handle of a knife 11 --- cylinder
2 --- coneheads 21 --- hold sword
22 --- side tool sword 23 --- chip areas.
Embodiment
The utility model is illustrated with reference to specific embodiment.
As shown in Figure 1-2, a kind of not equal portions screw tap, includes handle of a knife 1, the one end of handle of a knife 1 is connected with cone by cylinder 11
First 2, the upper end of conehead 2 is provided between three end swords 21 and corresponding and spiral side tool sword 22, end sword 21 and is provided with not
Spiral helicine chip area 23 is formed between the equal a of angle one, the a1 of angle two and the a2 of angle three, side tool sword 22, chip area 23 prolongs
Extend the upper end of cylinder 11.
Further, a of angle one between the end sword 21 is 115 °.
Further, the a1 of angle two between the end sword 21 is 120 °.
Further, the a2 of angle three between the end sword 21 is 125 °.
Need to further it explain, the utility model is provided with the unequal a of angle one, angle two between using end sword 21
The a1 and a2 of angle three, that is, hold the not equal portions of angle between sword 21, make vibrations cycle during cutting, it is to avoid the crest in vibrations cycle,
Trough is superimposed resonance, vibrations can be reduced, so that the silk tooth precision of endoporus is higher.
Above content is only preferred embodiment of the present utility model, for one of ordinary skill in the art, according to this reality
With new thought, it will change in specific embodiments and applications, this specification content should not be construed as
To limitation of the present utility model.
