Abstract
The utility model discloses a rotating table closed type constant-current hydrostatic guideway and relates to the technical field of mechanical equipment manufacturing. The rotating table closed type constant-current hydrostatic guideway comprises a gear ring and a sliding base embedded strip which are arranged between a rotating table and a supporting sliding base. The gear ring is fixedly connected with the rotating table. The sliding base embedded strip is arranged between the supporting sliding base and the gear ring. A hydrostatic oil cavity communicated with an oil supply system is arranged between the upper end face of the sliding base embedded strip and the lower end face of the gear ring. The supporting sliding base is connected with a guideway upper pressing plate which is provided with an oil way communicated with the oil supply system. A pressing plate embedded strip is arranged between the guideway upper pressing plate and the upper end face of the gear ring. An oil cavity communicated with the oil way of the guideway upper pressing plate is arranged between the lower end face of the pressing plate embedded strip and the upper end face of the gear ring. The problem that due to the fact that a hydrostatic guideway technology is used in a large machine tool, the unbalance-loading-resisting capacity of the rotating table is poor, and table floating amount fluctuation along with workpiece weight changing is high can be solved.
Description
Technical field
The utility model relates to plant equipment manufacturing technology field, especially a kind of guide rail for 20 tons of above revolution class workbench of load-bearing.
Background technology
Load-bearing all adopts hydrostatic slideway technology substantially now at more than 20 tons boring machine rotary tables, because whole workbench in full load big city over 40 tons, so adopt other guide rail structure frictional force larger, need the power of consumption more, the poor required precision that cannot meet use of dynamic response.Existing a kind of static-pressure guide rail structure is to be arranged at rotary table and to support gear ring between slide as the guide rail of rotary table, gear ring and rotary table are affixed, between support slide and the lower surface of gear ring, be provided with slide panel, between the upper surface of slide panel and the lower surface of gear ring, be provided with the static-pressure oil chamber communicating with oil supply system, to this static-pressure oil chamber, supply with after enough pressure oil, between slide panel and gear ring, form oil film, reduced coefficient of friction, effectively solved power consumption and the dynamic response problem of rotary table when revolution, but also there is following problem in the hydrostatic slideway of this structure: 1, changes in weight to supporting part is had relatively high expectations, the floatation volume of rotary table is larger with the fluctuation of workpiece changes in weight, cannot reach the instructions for use of precision machine tool, 2, its offset load resistance is poor, because the uniformity of oil film thickness of hydrostatic guide way is produced and had a strong impact on after unbalance loading, panoramic table cannot normally be worked, 3, theoretical oil film thickness and practical application of calculating has difference, and when designing and calculating, the less rotary table that may cause of value cannot float, if value causes turntable to drift about when working compared with conference during designing and calculating.
Utility model content
The purpose of this utility model is to provide a kind of rotary table enclosed constant-current static-pressure guide rail, and it can solve, and the rotary table offset load resistance that existing heavy duty machine tools adopt hydrostatic slideway technology to produce is poor, workbench floatation volume is with the larger problem of workpiece changes in weight fluctuation.
In order to address the above problem, the technical solution adopted in the utility model is: this rotary table enclosed constant-current static-pressure guide rail, comprise and be arranged at rotary table and support gear ring and the slide panel between slide, described gear ring and described rotary table are affixed, described slide panel is arranged between described support slide and described gear ring, between the upper surface of described slide panel and the lower surface of described gear ring, be provided with the static-pressure oil chamber communicating with oil supply system, described support slide is connected with guide rail top board, described guide rail top board is provided with the oil duct communicating with described oil supply system, between described guide rail top board and the upper surface of described gear ring, be provided with pressing plate panel, between the lower surface of described pressing plate panel and the upper surface of described gear ring, be provided with the oil pocket communicating with the oil duct of described guide rail top board.
In above technical scheme, further: described gear ring is connected with described rotary table with bolt by straight pin.
Further: described pressing plate panel is bonded in the lower plane of described guide rail top board; Described slide panel is bonded in the upper plane of described support slide.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, by set up pressing plate panel and the guide rail top board with oil pocket in gear ring upper surface, can form a downward hydrostatic pressure to gear ring, thereby effectively control the floatation volume of workbench, make the actual floatation volume of workbench reach fixing 0.04 millimeter;
2, two oil pockets that are communicated with oil supply system up and down of gear ring and its end face form enclosed constant-current static-pressure guide rail, can effectively overcome that rotary table offset load resistance is poor, workbench floatation volume is with the larger problem of workpiece changes in weight fluctuation, improved greatly the service precision of rotary table.
