Wherein, the sanding block is multiple, and is spaced apart and arranged on the upper surface of the cone seat.
Wherein, it is described thin to be fixedly connected or detachably connected between the thin-walled drill base and the cutter tip
To be fixedly connected or detachably connected between wall drilling pipe seat and the sanding block.
Wherein, the cutter tip is welded on the thin-walled drill base, and the sanding block is welded on the thin-walled
On drilling pipe seat.
Compared with immediate prior art, the dual-purpose grooved bit of abrasive drilling of the invention has the advantages that：
The dual-purpose grooved bit of abrasive drilling of the present invention, using the cutter tip of integral design structure so that grooved bit is drilling
During more impact, not fall tooth；And use the dual-purpose grooved bit of abrasive drilling of the present invention can be by the punching of stone material and bruting process
Once complete, significantly improve processing efficiency.
Brief description of the drawings
Fig. 1 is the top view of the dual-purpose grooved bit of abrasive drilling of the present invention.
Fig. 2 is cutting structural representations of the Fig. 1 along A directions.
Embodiment
The dual-purpose grooved bit of abrasive drilling of the present invention is further elaborated below with reference to specific embodiment, with to the present invention
Technical scheme make more complete and clear explanation.
Embodiment 1
As shown in Figure 1-2, the dual-purpose grooved bit of the abrasive drilling of the present embodiment, including thin-walled drill base 10, the thin-walled drill base
10 are made up of thin-walled drilling pipe 11 and thin-walled drill base 13, and the thin-walled drill base 13 includes cone seat 12 and is arranged on institute
The installation portion 14 stated in cone seat 12 and coordinated with rotating shaft.Connecting portion between the installation portion 14 and the cone seat 12
Multiple through holes 16 are provided with point.Specifically the thin-walled drilling pipe 11 can be process by seamless steel pipe, such as can be by common
No. 20 steel steel pipes obtained by cutting and drilling, the thin-walled drill base 13 can similarly be formed by No. 20 steel by machining
Cone seat 12 and installation portion 14, the thin-walled drilling pipe 11 and the thin-walled drill base 13 can be by mechanically connecting (such as spiral shell
Line) fix or by being welded and fixed.In addition, the thin-walled drilling pipe 11 can also be formed in one with the thin-walled drill base 13
Structure, such as can directly be formed by cold machining process such as machine cuts, punchings using No. 20 steel.In the present embodiment, institute
The cutter tip 20 that monoblock type is provided with thin-walled drill body is stated, specifically, the cutter tip 20 is cylindrical annular cutter head,
And thereon formed with cutting slot 22, the height of the cutting slot is the 1/5~1/3 of the cylindrical annular cutter head height.It is described
The thickness of cylindrical annular cutter head is more than the thickness of the thin-walled drill body.Using the cutter tip of integral design structure so that
Grooved bit has more impact in boring procedure, not fall tooth, is advantageous to improve rate of penetration.The upper surface of the cone seat 12
On be positioned apart from multiple sanding blocks 30, preferably, the sanding block is evenly distributed in the cone seat 12
Around, and each diamond molding block 30 has essentially identical shape and size, keeps suitable in polishing to enable
Freely run.Wanted according to actual, the angle a between the cone seat 12 and thin-walled drill body 11 meets：90 ° of ＜ a ＜
180 °, preferably 100 °≤a≤150 °, and the angle β between the sanding block and the thin-walled drill body and the cone
Seat is equal with the angle a between the thin-walled drill body.In the present embodiment, between the thin-walled drilling pipe and the cutter tip
Can be to be fixedly connected with (such as soldering etc., such as high-frequency induction brazing etc.) or detachably connected (such as screw), similarly, institute
State between thin-walled drill base and the sanding block to be fixedly connected or detachably connected.In the present invention, the cutter tip
Conventional sintering process can be used to obtain with sanding block, such as diamond can be used (or carbide, carbonitride etc. is hard
Matter particle etc.) and carcass powder carry out dispensing, be cold-pressed after batch mixing, then sinter by hot pressed sintering or freely and can obtain
Cutter tip and sanding block.With diamond particles for example, for cutter tip, recommendation use isostatic pressing strength for 30~
40 kilograms, granularity is 30/40 and/or 40/50 high-strength diamond particle, and can use isostatic pressing strength for sanding block as 25
~35 kilograms, granularity is 30/40 diamond particles.
The installation portion on drill head and thin-walled drill base is coordinated during use, drilling punching is carried out after energization, and then
The polishing for drilling out circular hole periphery can be carried out continuously and form certain taper, subsequently installed so as to convenient.Due to this reality
Example is applied using monoblock type cutter tip, there is rate of penetration to cut the characteristics of security is good soon, and drilling can nothing with polishing
Being carried out continuously for interruption drastically increases processing efficiency.
For the ordinary skill in the art, simply the present invention is exemplarily described for specific embodiment,
Obviously present invention specific implementation is not subject to the restrictions described above, and is entered as long as employing the inventive concept and technical scheme of the present invention
The improvement of capable various unsubstantialities, or it is not improved by the present invention design and technical scheme directly apply to other occasions
, within protection scope of the present invention.
