Abstract
The invention discloses a drilling bit which comprises an assembling sleeve, a transition sleeve and a cutting sleeve. A fixing pipe I in the assembling sleeve is connected with the transition sleeve in a threaded mode, the transition sleeve is connected with the cutting sleeve in a threaded mode, and a fixing pipe II in the assembling sleeve is connected with a power input shaft. Cutting edges and cutting grooves are formed at the free end of the cutting sleeve. A guiding hole is formed in the side wall of the transition sleeve. The axis of the fixing pipe I and the axis of the fixing pipe II are parallel, and the axis of the fixing pipe I, the axis of the transition sleeve and the axis of the cutting sleeve are located on the same straight line. Since the axis of the fixing pipe II and the axis of the fixing pipe I are parallel, the bore diameter of a drilled material is smaller than the bore diameter of the cutting sleeve, the situation that waste cannot be taken out of the cutting sleeve easily is avoided, and the service life of the cutting sleeve is prolonged; and the guiding hole facilitates discharging of chippings, and reinforcing ribs on the outer wall of the fixing pipe II can effectively improve the mechanical performance of the fixing pipe II.
Description
Technical field
The invention belongs to a kind of aperture processing unit (plant), and in particular to a kind of drill.
Background technology
Drill bit is a kind of common tool for removing materials processing aperture, and drill bit can be divided into following a few classes according to its profile or purposes：
Fluted drill, fluted drill are also most widely used aperture knife tool.General diameter scope is 0.25～80 millimeter.It is mainly made up of working portion and shank.Working portion has two spiral grooves, is similar to Flos Cannabiss, thus gains the name.In order to reduce friction during drilling between targeting part and hole wall, fluted drill is gradually reduced diameter in inverted cone shape from apex point to shank direction.
Chit drill, the cutting tip of chit drill is spade, simple structure, low cost of manufacture, and cutting fluid is easily in entrance hole, but cuts and chip removal poor-performing.
Depth drill, depth drill typically refer to cutter of the ratio more than 6 hole for processing hole depth and aperture.Conventional has drill gun, BTA depth drills, jet drilling, DF depth drills etc..Cylindrical drill is also commonly used for deep hole machining.
Reamer, reaming are drilled with 3～4 cutters tooth, and its rigidity is drilled than Flos Cannabiss, for expanding existing hole and improving machining accuracy and fineness.
Counterbit, counterbit have more cutter tooth, the profile needed for be processed into by nose end, for processing the counter sink of various sunk screws, or the outer face for scabbling hole.
Centre drill, centre bore of the centre drill for drilling shaft-like workpiece, it is substantially and is composited by the fluted drill and counterbit of helical angle very little, therefore also known as combination centre drill.
Core drill, is hollow in the middle of the drilling rod of core drill, is mainly used in boring thing coring.
But, also more or less existing is unsuitable for many phenomenons such as operation to drill bit in use.
The content of the invention
The present invention proposes to solve the problems, such as prior art, its objective is to provide a kind of drill.
The technical scheme is that：A kind of drill, including assembling set, spacer shell, cutting set, No. I fixing pipe in assembling set is threadedly coupled with spacer shell, spacer shell is connected with cutting external threading, No. II fixing pipe in assembling set is connected with power input shaft, and the free end for cutting set forms cutting edge, sword groove, and spacer shell side wall forms material guide hole, No. I fixing pipe, No. II fixing pipe axis it is parallel, described No. I fixing pipe, spacer shell, cutting set axis are same straight line.
Described No. I fixing pipe, No. II fixing pipe are formed in one, and the external diameter of No. I fixing pipe is more than the external diameter of No. II fixing pipe.
The fixed pipe outer wall of described No. II is provided with multiple and its diameter parallel reinforcement.
Described material guide hole is circular or oval.
The diamond of high pressure-temperature sintering is provided with the cutting edge, sword groove.
The sword groove bottom land is circular arc or fold-line-shaped.
Setting of the present invention by No. II fixing pipe and No. I fixing pipe diameter parallel, so that the aperture of the aperture less than cutting set of material is removed after perforate, avoid waste material to be not easy from cutting set to take out, the service life of cutting set is also increased simultaneously, material guide hole can be easy to chip to discharge, and the reinforcement at No. II fixed pipe outer wall can effectively improve the mechanical property of No. II fixing pipe.

Wherein：
1 assembling set
2 spacer shells
3 cutting sets
4 No. I fixing pipes
5 No. II fixing pipes

Specific embodiment
Hereinafter, referring to the drawings and embodiment the present invention is described in detail：
As shown in figure 1, a kind of drill, including assembling set 1, spacer shell 2, cutting set 3, No. I fixing pipe 4 assembled in set 1 is threadedly coupled with spacer shell 2, and spacer shell 2 is threadedly coupled with cutting set 3, and assembling covers No. II fixing pipe 5 and power input shaft in 1（It is not shown）It is connected, the free end of cutting set 3 forms cutting edge 6, sword groove 7, and 2 side wall of spacer shell forms material guide hole 8, and the axis of 4, No. II fixing pipe 5 of No. I fixing pipe is parallel, described No. I fixing pipe 4, spacer shell 2, cutting 3 axis of set are same straight line.
That is power input shaft is not coaxial with cutting set 3.In the case of power input shaft covers 3 out-of-alignments with cutting, the material external diameter that perforate is removed can be made to be less than the aperture of cutting set 3, that is to say, that to be not in the material of card full gate hole removal in the aperture for cut set 3, reduce the feeding link in the middle of the course of processing twice.
Described 4, No. II fixing pipe 5 of No. I fixing pipe is formed in one, and the external diameter of No. I fixing pipe 4 is more than the external diameter of No. II fixing pipe 5.Axis so as to realize 4, No. II fixing pipe 5 of No. I fixing pipe is parallel.
No. II described 5 outer wall of fixing pipe is provided with multiple and its diameter parallel reinforcement 9.Increase the mechanical property of No. II fixing pipe 5.
Described material guide hole 8 is circular or oval.
The diamond of high pressure-temperature sintering is provided with the cutting edge 6, sword groove 7.
7 bottom land of sword groove is circular arc or fold-line-shaped.It is easy to chip to discharge.
Setting of the present invention by No. II fixing pipe and No. I fixing pipe diameter parallel, so that the aperture of the aperture less than cutting set of material is removed after perforate, avoid waste material to be not easy from cutting set to take out, the service life of cutting set is also increased simultaneously, material guide hole can be easy to chip to discharge, and the reinforcement at No. II fixed pipe outer wall can effectively improve the mechanical property of No. II fixing pipe.
