Abstract
The utility model discloses an inner cooled wear-free drill comprising a drill handle and a drill body that are integrally formed, wherein the drill body is provided with two spiral chip grooves; the middle position of the end surface of the drill body is provided with a groove, in which a detachable cutting blade is fixed; the central position of the end part of the drill handle, toward the direction of the drill body, is provided with a cooling liquid hole used for conducting cooling liquid; and the cooling liquid hole extends to the tail end of the drill body and is communicated with two cooling liquid outlets arranged at the end surface of the drill body. For the inner cooled wear-free drill, the structure is simple; and the cooling liquid hole is arranged inside the inner cooled wear-free drill, and the cooling liquid outlets communicated with the cooling liquid hole are arranged the end surface of the drill body, so that the wear-free drill can also be timely and fully cooled when being drilled in a workpiece, thus being beneficial to prolonging the service life of the wear-free drill and further reducing the production cost of enterprises, saving resources and being beneficial to environmental protection.
Description
Technical field
The utility model relates to drill bit, and particularly a kind of inner-cooled in the inner conducting cooling fluid of brill body is exempted from abrasive drilling.
Background technology
In the prior art, all need to cool off drill bit when using drill bit by cooling fluid, so as not to the high heat of fricative high temperature between drill bit and the processing work drill bit and processing work are burnt out, traditional way all is in a side of drill bit a coolant pipe to be installed, and walks by not arrheaing the high torrid zone of high temperature that produces when moving cooling fluid is worked drill bit.This method is continued to use after proposition cooling theory always, does not make what change.But such cooling means is not perfect, because coolant pipe can only be located at a side of drill bit, the side near coolant pipe is good inadequately for the cooling effect of inevitable opposite side, thus cause uneven in temperature, simultaneously, when drill bit is drilled in the workpiece, gap between boring and the drill bit is little, and is rapid inadequately in the cooling fluid ostium, and amount is few, thereby cause the drill bit end can not in time obtain cooling, the phenomenon that burns out drill bit and workpiece happens occasionally.
The utility model content
The purpose of this utility model is, provide a kind of inner-cooled reasonable in design to exempt from abrasive drilling, by the inside of exempting from abrasive drilling at inner-cooled the cooling fluid hole is set, boring the cooling liquid outlet that the setting of body end face communicates with the cooling fluid hole, thereby, help prolonging the working life of exempting from abrasive drilling when exempting from also can in time fully to be cooled off when abrasive drilling is drilled in the workpiece.
The technical scheme that the utility model is adopted for achieving the above object is:
A kind of inner-cooled is exempted from abrasive drilling, it comprises integrated drillstock and bores body, described brill is provided with two helical flutes on one's body, be provided with a groove in described brill body end face centre position, one dismountable cutting tip is fixed in this groove, be provided with a cooling fluid hole that is used for the conducting cooling fluid by center, described drillstock end toward boring the body direction, this cooling fluid hole extends to that to bore body terminal and be located at the cooling liquid outlets that bore the body end face and communicate with two.
As further improvement of the utility model, described two cooling liquid outlets are located at described groove both sides respectively.
As further improvement of the utility model, be respectively equipped with a screw hole on the two side of described groove, the screw hole of corresponding described recess sidewall is respectively equipped with a perforate on the described cutting tip, and described cutting tip is fixed on described brill body end by screw.
The beneficial effects of the utility model are: the utility model is rational in infrastructure, by the inside of exempting from abrasive drilling at inner-cooled the cooling fluid hole is set, boring the cooling liquid outlet that the setting of body end face communicates with the cooling fluid hole, thereby when exempting from also can in time fully to be cooled off when abrasive drilling is drilled in the workpiece, help prolonging the working life of exempting from abrasive drilling, thereby reduced the production cost of enterprise, economized on resources, environmental.
Below in conjunction with accompanying drawing and embodiment, the utility model is further specified.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: see Fig. 1, a kind of inner-cooled of the utility model is exempted from abrasive drilling, it comprises integrated drillstock 11 and bores body 12, described brill body 12 is provided with two helical flutes 121, be provided with a groove 122 in described brill body 12 end face centre positions, one dismountable cutting tip 2 is fixed in this groove 122, be provided with a cooling fluid hole 123 that is used for the conducting cooling fluid by center, described drillstock 11 end toward boring body 12 directions, this cooling fluid hole 123 extends to that to bore body 12 terminal and be located at the cooling liquid outlets 124 that bore body 12 end faces and communicate with two.
Described two cooling liquid outlets 124 are located at described groove 122 both sides respectively.
Be respectively equipped with a screw hole 125 on the two side of described groove 122, the screw hole 125 of corresponding described groove 122 sidewalls is respectively equipped with a perforate on the described cutting tip 2, and described cutting tip 2 is fixed on described brill body 12 ends by screw.
Use the utility model processing work, when this inner-cooled is exempted from abrasive drilling work, cooling fluid is imported brill body 12 by cooling fluid hole 123 from drillstock 11, and by being located at cooling liquid outlet 124 eliminatings of boring body 12 end faces, also can access cooling timely in the workpiece even brill body 12 has pierced, help prolonging the working life that this inner-cooled is exempted from abrasive drilling.
As described in the utility model embodiment, exempt from abrasive drilling with other inner-cooleds of the same or similar structure of the utility model, all in the utility model protection domain.
