Abstract
The utility model discloses a kind of heat-resisting break-proof drill, by drill bit and get bore rod form, drill bit comprises blade, cools liquid bath, gets drill flute and drill body, and there is screw thread on drill body top, can be connected with motor, blade top is helical structure, facilitates chip removal, can not take out drill bit and directly inject cooling fluid and cool in the course of work, so that long time continuous working, if phenomenon of rupture occurs drill bit can bore rod taking-up with getting, structure is simple, easy to use.
Description
Technical field
The utility model relates to drill bit field, particularly relates to a kind of heat-resisting break-proof drill.
Background technology
Drill bit is instrument very important in a kind of machining, is mainly used in the roughing in hole.Along with the development of machinery industry, increasing to the demand of drill bit, sometimes the work that drill bit is long-term is needed, but drill bit long-term work can be generated heat, need bit change or drill bit is taken off cooling, use inconvenience, and drill bit can be caused to break in the device of needs processing due to the mistake in using or the quality problems of drill bit, broken end removal bothers very much.
Utility model content
The purpose of this utility model is to provide a kind of heat-resisting break-proof drill, to solve the above-mentioned multinomial defect caused in prior art.
For realizing above object, the utility model provides following technical scheme: a kind of heat-resisting break-proof drill, comprises drill bit and get boring rod, it is characterized in that: described drill bit top is drill body, there is screw thread on described drill body top, is blade below drill body, cooling liquid bath is had in described blade, liquid injection port is arranged at described cooling liquid bath top, and liquid outlet is arranged at bottom, and described cooling liquid bath gets drill flute, described brill rod of getting is cylinder, lever is arranged at top, and two salient points are arranged at bottom, and salient point can agree with getting drill flute.
Preferably, be taper bottom described blade, top is helical structure.
Preferably, described in get drill flute be a bar-shaped trough being parallel to drill body, bottom has one perpendicular to the little bar-shaped trough of drill body.
Preferably, described liquid outlet has wire netting.
Preferably, described lever there is finger type indenture.
The utility model has the advantage of: there is screw thread on drill body top, can be connected with motor, blade top is helical structure, facilitate chip removal, there is cooling liquid bath in drill bit, drill bit can not be taken out in the course of work and directly cool, so that long time continuous working from liquid injection port injection cooling fluid, cooling fluid trench bottom has liquid outlet, liquid outlet has wire netting, and cooling fluid can flow out and chip can not enter, if phenomenon of rupture occurs drill bit can bore rod taking-up with getting, structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the sectional view of drill bit;
Fig. 2 gets the sectional view boring rod;
Wherein: 1-drill body, 2-screw thread, 3-blade, 4-cools liquid bath, 5-liquid injection port, 6-liquid outlet, and 7-gets drill flute, and 8-gets and bores rod, 9-lever, 10-salient point, 11 indentures.
Detailed description of the invention
For making the technological means of utility model of the present invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with detailed description of the invention, set forth the present invention further.
As depicted in figs. 1 and 2, the utility model is a kind of heat-resisting break-proof drill, comprises drill bit and get boring rod 8, wherein drill bit comprises blade 3, cooling liquid bath 4, gets drill flute 7 and drill body 1, drill body 1 has screw thread, can be connected with motor, liquid injection port 5 is arranged at cooling liquid bath 4 top, liquid outlet 6 is arranged at bottom, and getting and boring rod 8 is cylinder, and lever 9 is arranged at top, two salient points 10 are arranged at bottom, salient point 1 can agree with getting drill flute 7, and on lever, 9 have finger type indenture 11, conveniently hold.
Add man-hour, blade 3 top is helical structure, facilitate chip removal, as Driller Exothermic, drill bit can not be taken out directly inject cooling fluid from liquid injection port 5 and cool, so that long time continuous working, liquid outlet 6 is had bottom cooling liquid bath 4, liquid outlet 6 has wire netting, and cooling fluid can flow out and chip can not enter, if Drill Crack is at inside workpiece, can hold lever 9 will get bore rod 8 insert get drill flute 7 to bottom, turn clockwise to get and bore rod 8, salient point 10 is snapped in and gets the little bar-shaped trough in drill flute bottom, just can take out broken end easily.
As known by the technical knowledge, the utility model can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Allly all to be included in the utility model within the scope of the utility model or being equal to the change in scope of the present utility model.
