Abstract
The utility model discloses a kind of new drill, belong to machining equipment field, described equipment comprises: helicla flute, main cutting head, cooling through hole, groove, drillstock, annular knurl line, working portion; The groove that employing is arranged at drillstock place and annular knurl line can be fixed on drill bit in drill jig firmly, prevent drill bit in the process used from beating in drill jig, the generation caused the accident; Cooling medium, by through the cooling through hole in working portion and drillstock, enters into drill hole and cools main cutting head, can take away chip simultaneously, reduce the cutting temperature of main cutting head, extend the service life of main cutting head, the utility model structure is simple, easy to use.
Description
Technical field
The utility model discloses a kind of new drill, belong to machining equipment field.
Background technology
The drill bit of prior art comprises working portion and shank, working portion and shank link into an integrated entity, the surface of shank is even surface, add be clipped in man-hour in drill chuck or machine tool chief axis or tailstock hole in, because the drill handle part surface of this structure is even surface, when being arranged in the hole of drill chuck or machine tool chief axis or tailstock, frictional force between shank and chuck is little, makes drill bit be not easy clamping, and to drill bit is clamped, just need larger clamping force, use inconvenience.
Common drill bit is made up of shank and working portion, wherein, working portion generally includes cutting edge and targeting part, targeting part is provided with the groove for deslagging, this drill bit structure is when Drilling operation, and drill bit easily generates heat, if cooling drill bit not in time, the as easy as rolling off a log damage causing bit cutting head, affects the normal work of drill bit.
Summary of the invention
In order to overcome problems of the prior art, the utility model provides a kind of new drill, adopt and groove and annular knurl line are set at drillstock place, drill bit can be fixed in drill jig firmly, prevent drill bit in the process used from beating in drill jig, the generation caused the accident, cooling medium passes through through the cooling through hole in working portion and drillstock, enter into drill hole to cool main cutting head, chip can be taken away simultaneously, reduce the cutting temperature of main cutting head, extend the service life of main cutting head.
For achieving the above object, the utility model provides following technical scheme:
A kind of new drill, described equipment comprises helicla flute 1, main cutting 2, cooling through hole 3, groove 4, drillstock 5, annular knurl line 6; Described groove 4 is arranged on one end of drillstock 5, drillstock 5 is provided with annular knurl line 6, and the other end of drillstock 5 is working portion 7, and helicla flute 1 is arranged on working portion 7, and main cutting 2 is arranged on one end of working portion 7, and cooling through hole 3 is arranged in main cutting 2.
Described cooling through hole 3 in drill body in the shape of a spiral.
Described cooling through hole 3 runs through working portion 7 and drillstock 5.
The beneficial effects of the utility model: adopt and groove and annular knurl line are set at drillstock place, drill bit can be fixed in drill jig firmly, prevent drill bit in the process used from beating in drill jig, the generation caused the accident, cooling medium, by through the cooling through hole in working portion and drillstock, enters into drill hole and cools main cutting head, can take away chip simultaneously, reduce the cutting temperature of main cutting head, extend the service life of main cutting head.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model right view;
Fig. 3 is the utility model left view;
In figure, 1-helicla flute, 2-main cutting head, 3-cool through hole, 4-groove, 5-drillstock, 6-annular knurl line, 7-working portion.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to facilitate the technical staff to understand.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of new drill, described equipment comprises: helicla flute 1, main cutting 2, cooling through hole 3, groove 4, drillstock 5, annular knurl line 6, working portion 7; Described groove 4 is arranged on one end of drillstock 5, drillstock 5 is provided with annular knurl line 6; The groove 4 that employing is arranged at drillstock 5 place and annular knurl line 6 can be fixed on drill bit in drill jig firmly, prevent drill bit in the process used from beating in drill jig, the generation caused the accident.
The other end of described drillstock 5 is working portion 7, and helicla flute 1 is arranged on working portion 7, and main cutting 2 is arranged on one end of working portion 7, and cooling through hole 3 is arranged in main cutting 2; Cooling medium by through the cooling through hole 3 in working portion 7 and drillstock 5, enters into drill hole and cools main cutting 2, can take away chip simultaneously, reduces the cutting temperature of main cutting 2, extends the service life of main cutting 2.
The course of work of the present utility model:
By arrange annular knurl line 6 and groove 4 drillstock 5 is firmly arranged in drill jig, check and just can use well, when needs cool main cutting 2, cooling medium, by through the cooling through hole 3 in working portion 7 and drillstock 5, cools drill hole.
The utility model adopts and arranges groove and annular knurl line at drillstock place, drill bit can be fixed on brill firmly
In head-clamp, prevent drill bit in the process used from beating in drill jig, the generation caused the accident, cooling medium passes through through the cooling through hole in working portion and drillstock, enter into drill hole to cool main cutting head, can chip be taken away, reduce the cutting temperature of main cutting head, extend the service life of main cutting head.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
