Description
Technical field
The utility model relates to a kind of drill bit, and particularly a kind of high pressure water jets considers clearly cooling drill bit to be worth doing.
Background technology
Suspension is an important assembly in automobile, and it flexibly connects vehicle frame and wheel, is related to the load serviceability of automobile.Exteriorly, car suspension is a more difficult automobile assembly reaching perfect requirement, this is because suspension should meet the comfortableness requirement of automobile, meet the requirement of its control stability again, and suspension is only made up of some bars, cylinder and spring, but must not think that it is very simple, phase negative side is again in opposition to each other.Such as, in order to obtain good comfortableness, need the vibrations of buffering automobile greatly, such spring will design softer, but spring is soft settles and easily makes automobile brake " nodding ", accelerates " new line " and left and right rolls serious harmful trend, be unfavorable for turning to of automobile, easily cause automobile operation unstable.
And at present, for automotive suspension, carry out in the process of Drilling operation utilizing drill bit to it, along with drill bit is due to high speed operation, drill bit itself can decline blunt by fast heating, and in order to maintain the normal work of drill bit, now needs to cool drill bit, traditional method sets up a cold water shower nozzle at the side of drill bit, and the cooling water utilizing cold water shower nozzle to spray cools drill bit.But adopt such method when cooling, can only cool the outer surface of drill bit, the internal cooling effect for drill bit is not fine.In addition for the automotive suspension of some top grades, high-precision requirement, carrying out in the process of holing, if the scrap got out by drill bit is not in time removed, then the precision that suspension can be caused to process due to the impact of these scrap reduces.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of good cooling results, and the high pressure water jets can removing scrap timely considers clearly cooling drill bit to be worth doing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of high pressure water jets considers clearly cooling drill bit to be worth doing, and its innovative point is: comprise a drill body and bare terminal end;
Described drill body encloses and rotates about the axis, the tail end of drill body is connected with bare terminal end, bare terminal end has the cavity that an appearance drill body embeds, the top of described drill body has an apopore, and described apopore one has two, and these two apopores are all connected with cooling water flow conduits, described cooling water flow conduits is positioned at the inside of drill body, and extend along the long axis direction of drill body, and extending to the end of bare terminal end always, described cooling water flow conduits is stepped.
Further, described cooling water flow conduits can be one runner, and the delivery port section of this runner has a point prong be connected with two apopores; Described cooling water flow conduits also can be twice runner, and this twice runner is corresponding with two apopores respectively.
Further, the rounded shape of described apopore, the bore of apopore is between 2.5mm-3.5mm.
Further, the bore of described cooling water flow conduits reduces from bare terminal end gradually to apopore direction.
Further, described cooling water flow conduits can be linear runner always, can be the spiral flow channel rotated along drill body.
The utility model has the advantage of: set up cooling water flow conduits by the inside at drill bit, high pressure is utilized to be sprayed from water outlet by the water in cooling water flow conduits, the cooling of drill bit internal can not only be realized, utilize water under high pressure the scrap that drill bit gets out can be taken out of together simultaneously, avoid the phenomenon affecting machining accuracy because of the existence of scrap; Cooling water flow conduits is designed to stepped, and bore reduces gradually, utilize constantly diminishing of volume, increase the pressure of water, thus more convenient removal scrap.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that high pressure water jets of the present utility model considers clearly cooling drill bit to be worth doing.
Detailed description of the invention
Schematic diagram is as shown in Figure 1 known, and high pressure water jets of the present utility model is considered clearly cooling drill bit to be worth doing and comprised a drill body 2 and bare terminal end 1.
Drill body 2 encloses and rotates about the axis, the tail end of drill body 2 is connected with bare terminal end 1, bare terminal end 1 has the cavity that an appearance drill body 2 embeds, on the top of drill body 2, there is an apopore, apopore one has two, and these two apopores are all connected with cooling water flow conduits 3, the rounded shape of apopore, the bore of apopore is between 2.5mm-3.5mm.
Cooling water flow conduits 3 is positioned at the inside of drill body 2, and extends along the long axis direction of drill body 2, and extends to the end of bare terminal end 1 always, and cooling water flow conduits 3 is stepped.
Cooling water flow conduits 3 can be one runner, and the delivery port section of this runner has a point prong be connected with two apopores, and the bore of cooling water flow conduits 3 reduces from bare terminal end gradually to apopore direction.In the present embodiment, cooling water flow conduits 3 also can be twice runner, and this twice runner is corresponding with two apopores respectively.Cooling water flow conduits 3 is designed to stepped, and bore reduces gradually, utilize constantly diminishing of volume, increase the pressure of water, thus more convenient removal scrap.
Cooling water flow conduits 3 can be linear runner always, can be the spiral flow channel rotated along drill body.
By setting up cooling water flow conduits 3 in the inside of drill body 2, high pressure is utilized to be sprayed from water outlet by the water in cooling water flow conduits, the cooling of drill body 2 inside can not only be realized, utilize water under high pressure the scrap that drill bit gets out can be taken out of together simultaneously, avoid the phenomenon affecting machining accuracy because of the existence of scrap.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
