Abstract
The invention relates to a screw tap with a drill bit for drilling a deep hole, which comprises the drill bit for a twist drill and the screw tap, wherein a handle part is arranged at the top end of the screw tap; a transition area is arranged between the drill bit and the screw tap; and the transition area is a cylinder with a smooth outer surface. According to the screw tap provided by the invention, the drill bit and the screw tap are combined with each other; after a hole is drilled by using the drill bit and the screw tap passes by a section of smooth transition area, the screw tap is directly used for processing an internal screw thread; the structure is simple; the tool need not be exchanged; and the accuracy is high. The screw tap provided by the invention has the advantages that the structure is simple, the manufacturing is convenient, the tool need not be exchanged, the time and labor are saved, and the processing precision is ensured.
Description
Technical field
The present invention relates to a kind of screw tap, a kind of specifically drilling deep hole is with the screw tap that has drill bit.
Background technology
In the time of the traditional processing through hole whorl; Normally, using the screw tap machining internal thread afterwards, so just needing two kinds of instruments earlier with circular hole of fluted drill processing; The replacing instrument; Not only time-consuming but also require great effort, and in the instrument of replacing, may cause certain damage to machining hole, accuracy is reduced.
Summary of the invention
In order to address the above problem, the invention provides the screw tap of the band drill bit that deep hole processing a kind of simple in structure, time saving and energy saving uses, this screw tap need not be changed instrument when deep hole processing, simple and convenient.
In order to achieve the above object, the present invention realizes through following technical scheme:
The present invention is the screw tap of a kind of drilling deep hole with the band drill bit, comprises the drill bit and the screw tap of fluted drill, and the top of screw tap is provided with shank, between drill bit and screw tap, is provided with transition region.
Further improvement of the present invention is: transition region is the slick and sly cylinder of appearance.
The invention has the beneficial effects as follows: screw tap of the present invention combines drill bit and screw tap, beats via hole through drill bit and directly can come machining internal thread with screw tap after the transition region through one section slyness afterwards, and is simple in structure, need not change instrument, and accuracy is high.
The present invention is simple in structure, and is easy to make, need not change instrument, time saving and energy saving, guarantees machining accuracy.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Wherein: 1-drill bit, 2-screw tap, 3-transition region, 4-shank.
The specific embodiment
In order to deepen to understanding of the present invention, will combine accompanying drawing and embodiment that the present invention is described in further detail below, this embodiment only is used to explain the present invention, protection scope of the present invention is not constituted to limit.
Shown in Fig. 1, the present invention is the screw tap of a kind of drilling deep hole with the band drill bit, comprises the drill bit 1 and screw tap 2 of fluted drill; The top of said screw tap 2 is provided with shank 4; The shank of drill bit and screw tap is combined into one, saves material, reduces production costs; Between said drill bit 1 and said screw tap 2, be provided with transition region 3, said transition region 3 is the slick and sly cylinder of appearance.Screw tap of the present invention combines drill bit and screw tap, beats via hole through drill bit and directly can come machining internal thread with screw tap after the transition region through one section slyness afterwards, and is simple in structure, need not change instrument, and accuracy is high.
The present invention is simple in structure, and is easy to make, need not change instrument, time saving and energy saving, guarantees machining accuracy.
