Description
Technical field
The utility model relates to a kind of lathe double-division auxiliary rotary table, is meant a kind of lathe double-division auxiliary static-pressure bearing and turning worktable especially.
Background technology
Tradition gear-hobbing machine rotary table generally adopts: the centripetal thrust force roller bearing with sliding bearing cooperate realize mandrel axially, radial location and revolution support.See accompanying drawing 1, traditional gear-hobbing machine rotary table comprises casing 2, support ring 8, mandrel 1, worm gear 5, active worm screw 6, damping worm screw 7, regulates annulus 4, table top 9, centripetal thrust force roller bearing 10, sliding bearing 3; Described support ring 8 is installed on the casing 2; Described worm gear 5 is fixed on the mandrel 1; Described active worm screw 6, damping worm screw 7 are installed in the casing and mesh with described worm gear 5; One table top 9 is installed on the described mandrel 1 and is in casing 2 upper surfaces; Described mandrel 1 upper end excircle is provided with centripetal thrust force roller bearing 10 and realizes the radial location of mandrel 1 upper end with described support ring 8; Described mandrel 1 lower end is a cone, which is provided with described sliding bearing 3 and centripetal thrust force roller bearing 10, regulate described sliding bearing 3 and the position of centripetal thrust force roller bearing 10 on described mandrel 1 lower end cone by the adjusting annulus 4 of being located at described mandrel 1 bottom, realize the axial location and the radial location of mandrel 1; The rotary table of this structure,
Though have rational in infrastructurely, advantage of high precision is because the existing defective of circular cone sliding bearing structure itself, in the use, the circular cone sliding bearing abrasion is big, the retentivity of temperature rise, precision is poor, causes the complete machine machining accuracy to reduce, and has influence on the precision of Gear Processing.
The utility model content
The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of simple and reasonable, processing and manufacturing easily, operate steadily, lathe double-division auxiliary static-pressure bearing and turning worktable that precision stability is good.
The utility model---a kind of lathe double-division auxiliary static-pressure bearing and turning worktable, comprise casing, support ring, the annulus pressing plate, mandrel, the active worm screw, the damping worm screw, worm gear, table top, described support ring is fixedly mounted on the upper surface of casing, described worm gear set is contained in an end of described mandrel, the other end of described mandrel is inserted in the central through hole of described support ring and by screw and table top and is connected as a single entity, be provided with a circle ring groove between described table top and the mandrel contact-making surface, the annulus pressing plate of fixedlying connected with described support ring is installed in the described groove, described active worm screw, the damping worm screw meshes in casing and with described worm gear by bearings, be evenly equipped with 4-20 oil groove that is communicated with external pressure oil pipe on described support ring and the described table top contact-making surface, be evenly equipped with the oil groove that 4-20 external pressure oil pipe is communicated with on described support ring and the described mandrel contact-making surface, be evenly equipped with the oil groove that the individual external pressure oil pipe of 4-20 is communicated with on described support ring and the described annulus pressing plate contact-making surface.
In the utility model, described external pressure oil pipe is made up of adjustable pressure oil inlet pipe and adjustable pressure flowline.
The utility model is owing to adopt said structure, between the surface of revolution of support ring, mandrel, table top, annulus pressing plate, a plurality of oil grooves are set, by regulating the oil pressure in the oil groove, make and evenly produce the oil film of thickness between two surfaces of revolution that are in contact with one another rapidly, on the one hand, table top is floated with respect to support ring is upwards micro-at 2～4 μ m, utilize oil film to bear axial load and form hydrostatic bearing, on the other hand, form oil film between annulus pressing plate and the mandrel upper surface, utilize oil film to bear axial load; In addition, between the cylindrical of the endoporus anchor ring of support ring and mandrel, produce oil film and form hydrostatic bearing, reach effect at the radial support mandrel.Effectively avoided the direct contact between the surface of revolution of support ring, mandrel, table top, annulus pressing plate; Because the formed oil film thickness of static pressure oil at 2～4 μ m, when realizing lubricated and reducing rubbing action, has increased the precision and the stability of workbench greatly.In sum, the utility model is simple and reasonable, processing and manufacturing is easy, operate steadily, rotating speed height, good rigidly, temperature rise is low, precision stability is good, can significantly improve the machining accuracy of workpiece, reliable operation is suitable for and the supporting use of the gear-hobbing machine of various models.
