Aiming at providing a device which can form a cooling liquid passage on the milling head, has an outlet located at the center of a milling cutter, and is good in cutter cooling effect and rotary sealing performance, simple in structure and practical, the utility model adopts the technical scheme that the rotary sealing device capable of discharging water from the center of the milling head comprises a step hole which is arranged on a main body and is coaxial with the main body, and a principal shaft is rotatably installed in the step hole through bearings, wherein the bearings are at least two in number and are respectively positioned at two end faces of the main body. The two bearings are separated by a gasket ring to form an annular hollow cavity for transferring the cooling fluid; a passage communicated with the annular hollow cavity is arranged on the main body; and a cooling fluid outlet is arranged at the other end of the passage. A passage is also arranged on the axis of the principal shaft; the outlet at one end of the passage is communicated with a liquid passage at the end face of a cutting tool; and the other end of the passage passes through the principal shaft in the radial direction to be communicated with the annular hollow cavity so as to form a cooling liquid flowing passage.
Description
Technical field
The utility model relates to a kind of sealing device of metal lathe, specifically is the center water outlet rotary seal of milling machine milling head.
Background technology
The type of cooling of conventional milling head (as the axial milling head of Fig. 4) only is the side cooling at milling head; Cooling fluid enters from import P, by outlet pipe S ejection milling cutter 12 is cooled off again.Produce bigger centrifugal force because cutter cuts under high rotating speed, make cutter surrounding air produce a powerful cyclone, blow away most of cooling fluid; Have only a small amount of cooling fluid to play the effect (or at all not entering the cutter blade) of cooling blade, cause cutter life to shorten; Particularly during deep hole machining, because of cooling off the not enough thermal wear that produces, also be unfavorable for chip removal easily, have a strong impact on the life-span and the working (machining) efficiency of drill bit.
The utility model content
The purpose of this utility model provides a kind of rotary seal of milling head, this device should be able to form the cooling passage of an outlet at the milling cutter center on milling head, have cutter good cooling results, good, the simple for structure practical characteristics of rotary sealing performance.
The purpose of this utility model is achieved through the following technical solutions: a kind of rotary seal of center water outlet milling head, comprise being arranged on the body and being installed in rotation on main shaft in this stepped hole that described bearing has two and be positioned at two end faces of body respectively at least with the coaxial stepped hole of body and by bearing; It is characterized in that being isolated into a toroidal cavity of carrying cooling fluid by sealing ring between two bearings, be shaped on a passage that communicates with this toroidal cavity on the described body, the other end of passage is a cooling liquid inlet; The axial location of described main shaft also is shaped on a path, and one of this path brings out mouth and communicates with the fluid passage of the end face of cutting tool, and the other end radially passes through main shaft and described toroidal cavity conducting, to form a complete coolant flow passage.
Be fitted with the sealing ring that prevents that cooling fluid from leaking on described two sealing rings respectively.
Described two sealing rings side of toroidal cavity dorsad also are shaped on a drainage trail respectively.
Operation principle of the present utility model is: the main shaft cutting fluid enters from the import P of body, enter main shaft by toroidal cavity between two sealing rings and the water hole 2B on the main shaft successively, passed through behind the whole cutter from the outlet ejection at the center, cutting end of cutter 12 at last, the cutter blade was cooled off along tool axis; And two sealing rings that are positioned at toroidal cavity are subjected to the effect of cutting fluid pressure, respectively with main shaft on and body on end face C, B be adjacent to, strengthened sealing effectiveness.The cooling fluid of small leakage is then reclaimed by the drainage trail.
The beneficial effects of the utility model are: the rotary seal that is provided is being guaranteed cooling fluid to cutting tool effectively under the prerequisite of cooling, utilizes coolant pressure to realize reliable isolation to cooling fluid; Simple and practical respond well, manufacturing cost is also low, has wide promotion prospect.
