Abstract
The utility model provides a directional cooling milling cutter, belongs to the technical field of machining, and particularly relates to a milling cutter used for a milling machine. The directional cooling milling cutter comprises a blind rivet, a shank and a cutter body, wherein blades are arranged at the lower part of the cutter body with a hollow structure; and a central through-hole is formed from the blind rivet at the upper end and the shank to the cutter body at the bottom, and is led to a central cavity of the cutter body. The directional cooling milling cutter is characterized in that a spray hole is formed in the wall of the cavity of the cutter body; and the spray orifice of the spray hole corresponds to the position of the blade. In the milling cutter with a simple structure, since a cooling medium spray orifice corresponds to the position of the blade, the spray orifice can be also aligned with the position of the blade for cooling regardless of high-speed rotation of the cutter, and the blade is cooled continuously, without being influenced by the shape of a workpiece to be processed, the cooling dead angle is eliminated, the cooling efficiency is improved, and meanwhile, the service life of the cutter is also prolonged.
Description
Technical field:
The directed cooling of the utility model 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, cools off bad meeting and 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 purpose of the utility model 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 purpose of the utility model is achieved in that
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 utility model is simple in structure, because the spout of the cooling medium of the utility model 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, do not receive 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. 2 is the internal structure sketch map of the utility model Fig. 1
Sketch map when Fig. 3 is the utility model processing work
The specific embodiment:
Below in conjunction with Fig. 1, Fig. 2 and Fig. 3, the utility model is further explained:
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 the spray-hole 6 of the utility model 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.
The operation principle of the utility model is:
As shown in Figure 3, the utility model 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 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, and 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, has guaranteed jet 61 corresponding to the position of blade 4 and has aimed at blade (blade) all the time and cool off, and has been that continuous blade (blade) is cooled off; Simultaneously; This injection cooling does not receive 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.
