The hydrostatic bearing rotary table disclosed by the utility model adopts a hydraulic system to drive the hoisting of the rotary worktable, and enhances the bearing capability, the service life of the hydrostatic bearing rotary table is prolonged; and the hydrostatic bearing rotary table has certain capability of polarizing a workpiece.
Description
Technical field
The utility model relates to precision machine tool and instrument field, particularly a kind of bearing of the hydrostatic pressure for the Precision Machining center.
Background technology
Along with machinery industry to future developments such as high speed, heavy duty, high accuracy, high-performance, to it, all have higher requirement in the aspects such as version, bearing capacity, high speed and dynamic property of the bearing of one of relevant key technology, in a lot of plant equipment, the bearing parts that are absolutely necessary, but general bearing load carrying capacity, high speed and dynamic property are poor, during use, serious wear, service life is often all shorter.
Summary of the invention
The purpose of this utility model is for existing bearing load carrying capacity, high speed and dynamic property described in background technology poor, during use, serious wear, service life is shorter problems all often, and a kind of hydrostatic pressure bearing turntable that can solve foregoing problems is provided.
The technical scheme that can realize goal of the invention of the present utility model is as follows:
A kind of hydrostatic pressure bearing turntable, it comprises rotary work sewing platform base and rotary table, the bottom of rotary table is along circumferentially be provided with several oil pockets symmetrically, the oil pocket below is provided with the throttling pin that passes into hydraulic oil, the throttling pin is connected with hydraulic fluid distributor, the rotating shaft of rotary table is fixedly connected with Workbench base, rotary table is fixedly connected with the bearing of rotating shaft, the rotary table below is provided with gear drive, the driven gear of gear drive is fixedly connected with rotary table, the rotating shaft of driving gear connects the worm gear of worm-and-wheel gear, worm screw is connected with the output shaft of motor.
The lower surface of described rotary table and the upper surface of Workbench base all pass through the shovel flower and process.By shoveling flower, make the surface smoothness of rotary table and Workbench base reach designing requirement, when being processed on rotary table, improves by workpiece the machining accuracy of workpiece.
For the ease of lifting and the rotation of rotary table, the oil pocket mouth place of described rotary table below is provided with ，Gai convex edge, convex edge and contacts with the rotary work sewing platform base.
Hydrostatic pressure bearing turntable of the present utility model, when needs rotate rotary table, hydraulic oil system by hydraulic fluid distributor to the even fuel feeding of each oil pocket, along with hydraulic oil enters oil pocket, rotary table steadily rises, when the discharge of the conveying capacity of hydraulic oil and oil pocket reaches balance, rotary table keeps original position, drive turbine and worm mechanism by motor, rotating shaft by turbine drives the driving gear rotation and then drives the driven gear rotation, make rotary table turn to precalculated position, then reduce the hydraulic system fuel feeding, make rotary table steadily drop to original position.Hydrostatic pressure bearing turntable of the present utility model, control the lifting of rotary table by hydraulic oil system, bearing capacity has obtained increasing substantially, and simultaneously, the wearing and tearing of bearing also can obtain basic solution, have extended the service life of rotary table.Because forwarding platform, liquid crystal last item of the present utility model continues fuel feeding by the oil outer pressing system in oil pocket, even so workpiece biasing to some extent on turntable, rely on and continue oil pressure when the certain oil float pressure of the inner arrival of turntable, turntable floats just can start to drive workpiece rotation, the accurate location of realizing workpiece.
