Description
Technical field
The present invention relates to a kind of spiral bit, particularly relate to set that there are three planes on a kind of bit sub face, and
The drill bit that the angle of three interplanars is 60 degree, belongs to tool-class.
Background technique
Currently, all variation with rapid changepl. never-ending changes and improvements is occurring for all trades and professions, so with the fast development of Chinese national economy
And tool, that is, drill bit for drilling is but ignored by people.Spiral bit is long-term in mechanical industry and relevant industries, a large amount of
It uses, is a kind of boring bar tool having a large capacity and a wide range, traditional spiral bit is by drill bit, the bar portion of drill bit, cutting edge, chip pocket etc.
It is integral, the utilization rate of drill bit is high in total, and the cutting edge of drill bit is easily damaged, and the bar portion of drill bit is shorter, uses
Get up with certain limitation, and drill shank is smooth cylinder, be easy to cause the phenomenon that clamping not tight drill slipping, is influenced
It also will cause the case where drill bit is scrapped while working efficiency and quality, therefore, being badly in need of one kind in the market can solve above ask
The spiral bit of topic.The object of the invention is that being related to a kind of clamp facilitates firm and steady triangular handle twist-drill,
And the detachable and interchangeable Novel twist drill of drill bit, with overcome the deficiencies in the prior art.
Summary of the invention
A kind of intensity is high, long service life in view of the deficiencies of the prior art, the present invention intends to providing, and clamps
Firm fluted drill.
To achieve the above object, the present invention provides the following technical scheme that
A kind of spiral bit, including drillstock and drill body, set that there are three planes on the drillstock, and the angle of three interplanars is each other
60 degree, the section of three planes composition is in equilateral triangle, and the center of equilateral triangle and the central axis of drill body coincide, institute
Stating drill body includes drill bit and the spiral helicine chip space and smooth section that are connected with drill bit, is passed through between the drillstock and the drill body
Removably connection.
A further improvement of the present invention is that: the drill bit is fully grinding drill bit, the conical cone angle of the drill bit is 125 ~
135 degree.
A further improvement of the present invention is that: the drill bit includes two cutting edges and apex point.
A further improvement of the present invention is that: the chip space is arranged between the drill bit and the smooth section.
A further improvement of the present invention is that: the drillstock is identical with the cross-sectional diameter of the drill body, and in the two
Mandrel line is overlapped.
A further improvement of the present invention is that: there is the abrasive particle of protrusion on the drillstock.
A further improvement of the present invention is that: the drill body helical angle size is 20 ~ 25 degree.
A further improvement of the present invention is that: the outermost diameter of the drill body is 1.68 ~ 1.75 millimeters.
A further improvement of the present invention is that: the drillstock, which is connected through a screw thread, to be fixed in the drill body, the drillstock and
Screw is additionally provided between drill body to fix,
In conclusion rationally, it is firm that clamping facilitates for design the present invention provides a kind of structure is simple, it is not easy to loosen, drilling efficiency
High and drill bit is detachable and interchangeable, is a kind of Novel auger bit of ideal type.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of drillstock cross section of the present invention.
Wherein: 1- drillstock, 2- drill body, 3- drill bit, 4- chip space, 5- smooth section.
Specific embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and is further retouched in detail
It states, the embodiment is only for explaining the present invention, does not constitute and limits to protection scope of the present invention.
The technical scheme is that
A kind of spiral bit, including drillstock 1 and drill body 2, set that there are three planes, and the angle of three interplanars on the drillstock 1
60 degree each other, the section of three planes composition is in equilateral triangle, and the center of equilateral triangle is mutually be overlapped with the central axis of drill body 2
It closes, the drill body 2 includes drill bit 3 and the spiral helicine chip space 4 and smooth section 5 that are connected with drill bit 3, the drillstock 1 and institute
It states and is connected by removably between drill body 2, the drill bit 3 is fully grinding drill bit, and the conical cone angle of the drill bit 3 is 135
Degree, the drill bit 3 include two cutting edges and apex point, and the chip space 4 is arranged between the drill bit 3 and the smooth section 5,
The drillstock 1 is identical with the cross-sectional diameter of the drill body 2, and the central axis of the two is overlapped, and has protrusion on the drillstock 1
Abrasive particle, the 2 helical angle size of drill body are 25 degree, and the outermost diameter of the drill body 2 is 1.75 millimeters, the drillstock 1
It is connected through a screw thread and is fixed in the drill body 2, be additionally provided with screw between the drillstock 1 and drill body 2 and fix, realize the drill bit 3
With the connection of the drill body 2, have the advantages that the advantages of easy to connect and connection effect is preferable, facilitates the replacement of drill bit, works as institute
When stating the damage of drill bit 3, drill body 2 is directly replaced, re-uses the drillstock 1, saves cost.
The beneficial effects of the present invention are: its structure is simple, design rationally, compared with prior art, can play and facilitate row
Bits and increase drill bit service efficiency and the structure by being fixedly welded play the role of increasing drillstock and drill body linking intensity,
So that spiral bit is more stable during the work time.
It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, above-described embodiment and explanation
It is merely illustrated the principles of the invention described in book, without departing from the spirit and scope of the present invention, the present invention also has
