Abstract
The utility model relates to fluted drill more particularly to a kind of stock fluted drills.It is stifled including spiral bit, taper pin, brill library, drilling rod and water flowing；Spiral bit, which is inserted in, to be bored in library, is positioned with taper pin；It bores library to connect with boring bar head by rectangular thread, water flowing is stifled to be fixed on drilling rod tail portion；Water flowing is stifled to pass through pipeline and high pressure water connection, and high-pressure water pressure is greater than 10MPa, is less than 200MPa.Structurally reasonable, crusher drill cutting edge is very convenient；When need to convert fluted drill length and specification, as long as replacement drilling rod and drill bit, use and its conveniently；Spiral bit is positioned with brill library with taper pin, prevents drill bit from, with the disengagement of brill library, preventing drill bit to be trapped in workpiece when falling to draw iron foam, preventing workpiece from scrapping；When spiral bit is cut, lead to high pressure water, cooling drill edge extends the bit cutting time, improves drill bit physical life.
Description
Technical field
The utility model relates to fluted drill more particularly to a kind of stock fluted drills.
Background technique
Fluted drill is the rotary cutting by its relatively fixed axis with the tool of the circular hole of drilling workpiece, because of its chip pocket
It is spiral and be similar to fried dough twist and gain the name.Currently, the domestic stock fluted drill generally used, is unable to quick-replaceable drill bit and brill
Bar.When work, as soon as cutting edge need to be ground again after deep meter of the every brill of drill bit；Because drilling rod is especially long, when crusher drill cutting edge, very
It is inconvenient；Some even can not crusher drill cutting edge, cause stock fluted drill to be scrapped.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of stock fluted drill.It is structurally reasonable, replacement
Drill bit, drilling rod are convenient, and crusher drill cutting edge is more convenient, improves the service life of drill bit.
In order to achieve the above object, the utility model is implemented with the following technical solutions:
A kind of stock fluted drill, including spiral bit, taper pin, brill library, drilling rod and water flowing are stifled；Spiral bit, which is inserted in, bores library
It is interior, it is positioned with taper pin；It bores library to connect with boring bar head by rectangular thread, water flowing is stifled to be fixed on drilling rod tail portion；Water flowing is stifled to be passed through
Pipeline and high pressure water connection, high-pressure water pressure are greater than 10MPa, are less than 200MPa.
The brill library head drills equipped with Mohs, and tail portion is equipped with rectangle external screw thread, and tail portion center is equipped with circular through hole.
The spiral bit tail portion is equipped with the taper hole being adapted to taper pin；The library head of boring is equipped with the cone being adapted to taper pin
Hole.
Compared with prior art, the utility model has the beneficial effects that
1, the utility model is structurally reasonable, as soon as spiral bit needs to grind cutting edge again after deep meter of the every brill of the long bar drill of fried dough twist,
At this moment, it can will bore library to screw down from drilling rod, convenient for grinding drill edge；
2, when need to convert fluted drill length and specification, as long as replacement drilling rod and drill bit, easy to use；
3, spiral bit is positioned with brill library with taper pin, is prevented drill bit when falling to draw iron foam and is bored library disengagement, drill bit is trapped in
In workpiece, workpiece is caused to be scrapped；
4, drilling rod tail portion is burn-on, and water flowing is stifled, and in spiral bit cutting, logical high pressure water, cooling drill edge extends and bores
The head cutting time.
Detailed description of the invention
Fig. 1 is stock fluted drill structural representation front view before improving；
Fig. 2 is the utility model structural representation main view sectional view；
Fig. 3 is the utility model structural representation top view.
In figure: 1- spiral bit 2- taper pin 3- bores the 5- water flowing of library 4- drilling rod and blocks up 6- circular through hole
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
A kind of stock fluted drill as shown in Figure 2 and Figure 3, including spiral bit 1, taper pin 2, brill library 3, drilling rod 4 and water flowing are stifled
5。
1 tail portion of spiral bit is taper, bores 3 head of library and drills equipped with Mohs, Mohs drilling and 1 tail portion phase of spiral bit
It answers, spiral bit 1, which is inserted in, to be bored in library 3.
1 tail portion side of spiral bit is equipped with the conical through-hole being adapted to taper pin 2, bores 3 head of library and is equipped with corresponding cone
Shape through-hole, spiral bit 1, which is inserted in, to be bored in library 3, is positioned by taper pin 2.
It bores 3 tail portion of library and is equipped with rectangle external screw thread, tail portion center is equipped withCircular through hole 6.4 head of drilling rod is equipped with rectangle
Internal screw thread bores 6 tail portion of library and is connect with 4 head of drilling rod by rectangular thread.
Water flowing stifled 5 is fixed on the end of drilling rod tail portion, and by pipeline and high pressure water connection, high-pressure water pressure is big for water flowing stifled 5
In 10MPa, it is less than 200MPa.
When work, as soon as spiral bit 1 need to grind cutting edge again after deep meter of the every brill of the long bar drill of fried dough twist.At this moment, library will can be bored
3 screw down from drilling rod 4, convenient for grinding to drill edge.
When need to convert fluted drill length and specification, drilling rod 4 and spiral bit 1, strong applicability, installing and dismounting side are replaced
Just quick.
Spiral bit 1 and brill library 3 use taper pin 2 to position, and are that spiral bit 1 is when falling to draw iron foam in order to prevent and brill library 3 is de-
It opens, prevents spiral bit 1 to be trapped in workpiece, workpiece is caused to be scrapped.
It burn-ons water flowing stifled 5 in 4 tail portion of drilling rod, is to when spiral bit is cut, lead to high pressure water, cooling bit cutting
Sword extends the bit cutting time.
The utility model, structurally reasonable, more bit change, 4 convenience of drilling rod, crusher drill cutting edge is more convenient, improves brill
The service life of head.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its design is subject to equivalent substitution or change, should be covered within the scope of the utility model.
Method therefor is conventional method unless otherwise instructed in above-described embodiment.
