The beneficial effects of the utility model are: utilize the original oilhole of milling machine, have installed the cooling device of milling cutter tool additional, have avoided Yin Gaowen and make cracking of cutter, effectively saved production cost in one end of milling cutter body.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the high pressure cooling device structural representation of cutter for milling machines;
In figure, 1, cutter hub; 2, bearing; 3, oil sealing; 4, bearing bracket stand; 5, gland; 6, spring; 7, oil guide plate; 8, blind rivet; 9, milling head.
Detailed description of the invention:
Embodiment: the following embodiment that utility model is described by particular specific embodiment, those skilled in the art can understand other advantages of the present utility model and effect easily by content disclosed in the present specification.
As shown in Figure 1, the high pressure cooling device of this cutter for milling machines comprises cutter hub 1, bearing 2, oil sealing 3, bearing bracket stand 4, gland 5, spring 6, oil guide plate 7, blind rivet 8, milling head 9.The male-tapered end of ST50 milling cutter body 1 is connected with lathe internal taper hole transmission driving force, the parallel end of milling cutter body 1 has vertical oil guiding hole, inside has conical cavity and installs milling head 9, milling head 9 miner diameter end has screwed hole, blind rivet 8 is fastenedly connected at the screwed hole of cutter hub 1 conical surface end and the screwed hole of milling cutter 9 miner diameter ends by opening, blind rivet 8 is hollow, vertical through hole is had in the vertical oil guiding hole intersection with cutter hub 1, the parallel end of cutter hub 1 is by by bearing 2, oil sealing 3, the sub-assembly parcel that bearing bracket stand 4 forms, bearing bracket stand 4 lower end connects the sub-assembly of gland 5 and spring 6, oil guide plate 7 is connected to the other end of the sub-assembly of gland 5 and spring 6.High pressure cold oil, by the oil through access to plant of oil guide plate 7, is pushed open gland 5 and spring 6, is entered the oil through of bearing bracket stand 4 by the centre bore of gland 5, and then enters milling head 9 pairs of milling heads 9 by the oilhole of blind rivet 8 and cool.
As shown in Figure 1, select the installation end diameter of its milling head 9 of ST50 milling cutter to be 50mm, selected blind rivet 8 diameter need coordinate with ST50 milling cutter diameter, therefore chooses M24 size blind rivet.
As shown in Figure 1, the milling cutter High Rotation Speed of this cooling device wrapped end, the radial load produced device is larger, and the roller of cylinder roller bearing and raceway are linear contact lay, the ability of bearing radial load is strong, and rolling element and lasso rib rub little, are applicable to high-speed rotary part.
As shown in Figure 1, cooling device is because be connected with high pressure cold oil, its seal is one of most important performance, for the fluid property that cold oil is special, chooses TC oil seal washer and closes it, TC oil seal washer is the two-lip seal of the completely coated band self-tightening spring of a kind of rubber, the sealing function of this kind of oil sealing is good, and service life is longer, and installation site is little, axial dimension is little, handling ease.
As shown in Figure 1, why cooling device is designed to the device of the similar check valve of gland 5 and spring 6, to prevent cold oil in gland 5 and the backflow of spring 6 place, so the cold oil pressure provided must even as big as pushing gland 5 open and spring 6 makes cold oil flow into.
As shown in Figure 1, the diameter of the oil through of oil guide plate 7 is less than the oil through diameter of bearing bracket stand 4 and blind rivet 8, this is the flow for ease of controlling the cold oil by gland 5 and spring 6, the cold oil flow passed into can not be too much, otherwise the internal bore pressures of milling head 9 can be made to increase, be unfavorable for the work of milling head 9, can not be too small, otherwise do not have the effect of cooling milling cutter head 9.
Described embodiment in order to illustrative the utility model, but not for limiting the utility model.Any those skilled in the art all without prejudice under spirit of the present utility model and category, can modify to described embodiment, therefore rights protection scope of the present utility model, should listed by claim of the present utility model.
