Abstract
A kind of pair of fan-shaped chamber static pressure panoramic table lubricating pad, belongs to heavily loaded class machine tool technology field.The main body of this pair of fan-shaped chamber static pressure panoramic table lubricating pad is fan-shaped lubricating pad, and the centre of fan-shaped lubricating pad is scalloped recess, and the scalloped recess is oil pocket, and oil inlet is arranged on the center of feeding oil pocket；Provided with sector convex body a and fan-shaped convex body b in oil pocket.Fan-shaped oil pocket not only increases loaded area, and biparting shape convex body structure reduces hydraulic oil volume in oil pocket, and the run at high speed heat of generation of turntable can be allowed to discharge rapidly；Sealing oil edge effect does not lose oil sealing effect simultaneously, it is ensured that the pressure inside oil pocket, it is ensured that its load-carrying properties.Then operating efficiency and the machining accuracy of lathe are improved, support is provided for the theoretical research of static pressure.
Description
Technical field
The present invention relates to a kind of fan-shaped chamber static pressure panoramic table lubricating pad with rounded corners, belong to heavily loaded class machine tool technology field.
Background technology
Static pressure turntable is widely used in a little China because its load-carrying properties is good, frictional force is small, rigidity is high and rotating speed is high etc.
In heavily loaded class high-grade, digitally controlled machine tools.Under turntable high-speed overload operating condition, the increase of oil pocket pressure, oil film thickness caused by temperature rise
Diminish, bearing capacity diminishes.The reduction of turntable running efficiency is in turn resulted in, machining accuracy declines, and has a strong impact on part processing precision,
Serious influence is caused for heavy parts.
The content of the invention
Emphasis of the present invention solves static pressure turntable lubricating oil temperature rise problems of too under operating mode when high speed is long, improves holding for lubricating pad
Performance is carried, so as to propose a kind of more rational, structure uncomplicated pair of fan-shaped chamber static pressure oil pad captures this technical barrier.
It is as follows in order to solve this problem the technical solution adopted by the present invention：A kind of pair of fan-shaped chamber static pressure panoramic table lubricating pad,
It is characterized in that：The main body of this pair of fan-shaped chamber static pressure panoramic table lubricating pad is fan-shaped lubricating pad 1, and the centre of fan-shaped lubricating pad 1 is fan-shaped recessed
Groove, the scalloped recess is oil pocket 1.2, and oil inlet 1.1 is arranged on the center of feeding oil pocket 1.2；Provided with fan-shaped convex body in oil pocket 1.2
A1.3 and fan-shaped convex body b1.4, fan-shaped convex body a (1.3) and sector convex body b (1.4) are arranged in juxtaposition.
Each fan-shaped lubricating pad 1 is uniformly arranged on base 2, and turntable table top is arranged on the surface of each fan-shaped lubricating pad 1.
Oil pocket 1.2 it is parallel when corresponding with fan-shaped lubricating pad 1, the side of oil pocket 1.2 along the circumferential direction is all arc.
This hair has following benefit compared with existing technology：Fan-shaped oil pocket not only increases loaded area, and biparting shape
Convex body structure reduces hydraulic oil volume in oil pocket, and the run at high speed heat of generation of turntable can be allowed to discharge rapidly；
Sealing oil edge effect does not lose oil sealing effect simultaneously, it is ensured that the pressure inside oil pocket, it is ensured that its load-carrying properties.Then improve
The machining accuracy of operating efficiency and lathe, support is provided for the theoretical research of static pressure.
Brief description of the drawings
Fig. 1 is lubricating pad 3 dimensional drawing；
Fig. 2 is lubricating pad top view；
Fig. 3 is that lubricating pad arranges schematic diagram along turret base；
Embodiment
This lubricating pad is illustrated with reference to Figure of description.
The agent model of double fan-shaped chamber static pressure panoramic table lubricating pads is fan-shaped lubricating pad, and centre is two fan-shaped convex bodys side by side.
The total thickness of lubricating pad is 18mm, and oil pocket depth is 5mm, and lubricating pad outer arc radius is 1250mm, and inner arc radius is 1130mm, fan
Shape central angle is 36 degree.The oil inlet of oil pocket is arranged on the geometric center position of lubricating pad main body, is easy to lubricating oil to be diffused into whole
In individual oil pocket.
Operation principle：The fan-shaped lubricating pad 1 of 10 identicals is uniformly arranged on base 2 during work, turntable table top is installed
Directly over lubricating pad.Lubricating oil is sent into oil pocket 1.2 by oil pump from oil inlet 1.1, is finally full of oil pocket 1.2, is passed through 10 lubricating pads
Oil pocket pressure support turntable and the workpiece that loads thereon make gyration.Closely and between lubricating pad and turntable form one layer of 5mm
The oil film of left and right, produces pressure support, forms static pressure oil drag.
The design is arranged side by side fan-shaped convex body a13 with fan-shaped convex body b1.4 inside fan-shaped oil pocket, and this structure does not have not only
The big loaded area of fan-shaped oil pocket is reduced, and reduces oil pocket inner fluid flow, the area of dissipation of fluid is increased so that profit
Lubricating oil temperature rise reduces, and the greasy property of static pressure oil pad is ensured.
The power due to friction consumption is greatly reduced, improve the running efficiency of turntable, so as to turntable at work
The problem of fluid temperature rise of generation is excessive and load-carrying properties are reduced has obtained preliminary solution, improves the processing effect of static pressure turntable
The operating accuracy of rate.
