Abstract
The invention provides a plane bearing for a vertical type lathe. The plane bearing comprises an upper separation blade, a supporting mechanism, a retaining frame and a lower separation blade. The plane bearing is characterized in that the supporting mechanism is a thrust bearing; inner sides of the upper separation blade and the lower separation blade of the bearing are respectively provided with annular guide rolling paths; and the upper separation blade and the lower separation blade of the bearing are respectively fixed on a working table face and a base. The plane bearing for the vertical type lathe better solves the precision problem of a machine tool, the rigidity of the bearing is good, the precision keeping period is long and the plane bearing is energy-saving and environment-friendly; the instant size change is not easy to cause and a heavier machining work piece can be borne; and the plane bearing for the vertical type lathe has the advantages of simple starting process, convenience for operation, good lubrication effect and difficulty in damaging a rail.
Description
Technical field
The present invention relates to a kind of plane bearing, be applied to vertical lathe.
Background technique
At present, known vertical lathe adopts the plane static pressure type to support between table top and the base.The worktable running accuracy of this supporting way is not high, causes the instantaneous time dimensional variations easily, and start-up course is complicated; Operation inconvenience; And hydrostatic bearing is difficult to float when processing heavier workpiece, and rotation was fluctuateed greatly when workpiece was laid particular stress on, and the commentaries on classics degree reduces; When oil pump damage or oil circuit obstruction, damage track easily.
Summary of the invention
In order to overcome the static pressure track structural imperfection of traditional vertical lathe; The invention provides the annular guiding raceway plane bearing that a kind of pattern is novel, structure is unique; Its cross section is one section circular arc or rectangle, and its rigidity is high, can bear heavier operative workpiece; Ring raceway can be designed to together or multiple tracks according to workpiece weight, and is applied widely.Well solved the machine tool accuracy problem, the precision maintenance phase is long, and the unit bearing capacity is little, is not easy to cause the instantaneous time dimensional variations, and start-up course is simple, and is easy to operate, is not easy to damage track.
The technological scheme that technical problem adopted that the present invention solves is: the inboard of the upper and lower catch of bearing is processed into annular guiding raceway respectively, is individually fixed in the upper and lower catch of the bearing that processes on table top and the base.Ball or cylindrical roller are placed in the retainer; Then it is placed on above the lower stop piece ring raceway of corresponding base together; Raceway and middle the support through rolling element of the lower stop piece on the base with the upper stop piece on the table top is combined together again, at last with above the main shaft of stationary table on base.On raceway, add lubricant oil, thereby reduced the temperature of bearing working and reduced the inner friction factor of bearing through circulating cooling system.
The invention has the beneficial effects as follows: well solved the precision problem of lathe, bearing rigidity is good, and the precision maintenance phase is long, energy-conserving and environment-protective; Be not easy to cause the instantaneous time dimensional variations, can bear heavier operative workpiece, start-up course is simple; Easy to operate, greasy property is good, is not easy to damage track.
