Abstract
The invention discloses a directional cooling milling cutter belonging to the technical field of mechanical processing, and particularly relates to a milling cutter for a milling machine. The directional cooling milling cutter comprises a blind rivet, a cutter handle and a cutter body, wherein a blade is arranged below the cutter body; the cutter body is of a hollow structure; a central through hole is arranged from the blind rivet and cutter handle at the upper end to the cutter body at the bottom, and the central through hole extends into the hollow cavity of the cutter body; the directional cooling milling cutter is characterized in that: an injection hole is formed on the cavity wall of the cutter body; and the injection orifice of the injection hole corresponds to the position of the blade. The directional cooling milling cutter disclosed by the invention has a simple structure; as the injection orifice of the cooling medium corresponds to the position of the blade, the injection orifice is always directed at the position of the blade for sure for cooling in spite of the high-speed rotation of the cutter; and the blade is continuously cooled without suffering influence of the workpiece shape, thereby eliminating the cooling dead angle, improving the cooling efficiency and prolonging the service life of the cutter.
Description
Technical field:
The directed cooling of the present invention milling cutter, it belongs to the Machining Technology field, particularly a kind of milling cutter that is used for milling machine.
Background technology:
General milling machine adopts fixed cooling tube to cool off; Owing to workpiece shape, cutter and workpiece relative position are not stopped paying out reasons such as changing; The cooling medium of fixing cooling tube ejection can not arrive all milling positions; Possibly there is the cooling dead angle in milling cutter in process; Cooling fluid can't be ejected into blade (blade) position of Tool in Cutting; Cooling off bad meeting causes the life-span minimizing and the crudy of cutter not good; Disc type milling cutter particularly, prior art also can't solve the problem at cooling dead angle at present.
Chinese patent " the cutter collet chuck with water-supplying structure ", the patent No. is to have related to the Tool Design with certain cooling cooling capacity in 200820102788.7.It is water-cooled that but to be external slot water outlet with cutter go out for it, and this scheme is fit to the cooling of slotting cutter, can not be applied to the disc type milling cutter.
All provided the milling cutter cooling scheme in disclosed " a kind of center water outlet cutter " in disclosed " a kind of center water outlet cutter " and No. 200910201429.6 in Chinese patent No. 201020166351.7 disclosed " a kind of center water outlet cutter " and No. 200810200624.2 with reverse water outlet; But the water jet of its design is to form downwards or to two apopores of side direction, can not realize not having the cooling effect at dead angle.And three above-mentioned patented technology schemes all can only be applicable to the chip removal and the cooling of deep hole processing, can not realize the running that can't cool off the dead angle of common disc type milling cutter.
Summary of the invention:
The object of the present invention is to provide a kind of disc type milling cutter of realizing not have the orientation cooling milling cutter of cooling dead angle running.
The objective of the invention is to realize like this:
A kind of directed cooling milling cutter, it comprises blind rivet, handle of a knife and cutter body, described blade is arranged on the below of cutter body; Described cutter body is a hollow structure, and the cutter body from the blind rivet of upper end and handle of a knife to the bottom is provided with a central through hole, and described central through hole feeds in the center cavity of cutter body; It is characterized in that a spray-hole is set on the cavity wall of described cutter body, the jet of described spray-hole is corresponding to the position of blade.
Described spray-hole is distributed on the circumference of cavity wall of cutter body.
The quantity of the spray-hole on the described cutter body cavity wall is identical with the quantity of blade on being arranged on cutter body.
The present invention is simple in structure; Because the spout of cooling medium of the present invention is corresponding to the position of blade; Though cutter is in rotation at a high speed; Can guarantee that also jet aims at the position of blade all the time and cool off; And be that continuous blade is cooled off, be not subjected to the influence of processing work shape, eliminated the cooling dead angle; Improve cooling effectiveness, also prolonged the service life of cutter simultaneously.
Description of drawings:
Fig. 1 is a structural representation of the present invention
Fig. 2 is the internal structure sketch map of Fig. 1 of the present invention
The sketch map of Fig. 3 during for processing work of the present invention
The specific embodiment:
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the present invention is further illustrated:
In the present embodiment, invention comprises blind rivet 1, handle of a knife 2 and cutter body 3, and described blade 4 is arranged on the below of cutter body 3; Described cutter body 3 is a hollow structure, and the cutter body 3 from the blind rivet of upper end 1 and handle of a knife 2 to the bottom is provided with a central through hole 5, in the center cavity 31 of described central through hole 5 feeding cutter bodies 3; One spray-hole 6 is set on the cavity wall 32 of described cutter body 3, the jet 61 of described spray-hole 6 that is to say corresponding to the position of blade 4, and the jet 61 of spray-hole 6 of the present invention is always levied the blade position.Described spray-hole 6 is distributed on the circumference of cavity wall 32 of cutter body 3.The quantity of the spray-hole 6 on the described cutter body cavity wall 32 is identical with the quantity of blade on being arranged on cutter body 3.
Operation principle of the present invention is:
As shown in Figure 3; The present invention is the disc type milling cutter; When cutter need add man-hour to the inside of a workpiece 7; The blade of its cutter will move in the endoporus 71 of workpiece 7; Be that blade 4 will be rotated motion and accomplish processing action; At this moment; Cooling medium is fed through the inlet of supercharging equipment by the central through hole 5 at cutter top; At this moment; Cooling medium itself has just had certain pressure; When cutter rotated, cooling medium was directly injected to the position that needs cooling through the jet 61 of cavity 31 and spray-hole 6.Though cutter is in rotation at a high speed; Because spray-hole 6 is corresponding to the position of blade 4; Guaranteed that jet 61 aims at blade (blade) all the time and cool off; And be that continuous blade (blade) is cooled off; Simultaneously; This injection cooling is not subjected to the influence of workpiece to be machined shape, therefore can thoroughly eliminate the cooling dead angle, guarantees normally carrying out of processing.Supercharging equipment described in the present embodiment can be equipment such as water pump, mainly is to guarantee when the jet 61 of cooling medium through central through hole 5, cavity 31 and spray-hole 6, to have certain pressure.
