Description
Technical field
The utility model relates to lathe, relates in particular to top that lathe uses.
Background technology
Lathe is when processing work, for precision and the axiality that guarantees workpiece, a top workpiece that withstands is installed at the lathe tail end in the capital, in process, owing to can making workpiece tail end and top contact position that friction takes place, the high speed rotation of workpiece reduces top service life, also will make workpiece axial runout take place adding man-hour when serious, reduce the precision of workpiece, in order to reduce wearing and tearing, operating personnel are when installing and fixing workpiece, lubricating grease is spread at workpiece tail end and top contact position in the capital, this mode poor effect, and bothersome effort.
The utility model content
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can effectively reduce the top of wearing and tearing.
The technical solution of the utility model is: a kind of top, comprise top body and centre head and be nested with tapered sleeve on centre head, described top body and centre head inside are provided with the lubricated liquid bath of a perforation, described lubricated liquid bath runs through top body and centre head, top body tail end is provided with the bolt of blocking lubricated liquid bath, described bolt is provided with leakproof plastic cement pad, the centre head tip is provided with and is connected with lubricated liquid bath, tapered sleeve is provided with aperture, aperture and lubricated liquid bath connect, described tapered sleeve also is provided with spiral helicine groove in appearance, and described groove is connected with aperture.
The beneficial effects of the utility model are: lubricating fluid flows to the contact position of tapered sleeve and workpiece continuously by lubrication groove process and aperture, has effectively reduced wearing and tearing, and has played certain cooling effect.
