The utility model content
Technical problem to be solved in the utility model is: a kind of carrying working ability that improves lathe is provided, prolongs the service life of base rail, guarantee that workbench has the rotary table device of the double column vertical lathes of good kinematic accuracy.
Solve this technical problem, the technical solution of the utility model is: a kind of rotary table device of double column vertical lathes, the workbench rotating disk that comprises base and base top, described base upper surface is provided with a plurality of uniform in the form of a ring rail units that cooperate with the workbench rotating disk that have, each rail unit has the oil pocket in guide pass and the guide pass zone, the workbench rotating disk is provided with a constant current hydrostatic slideway system outward, and this constant current static pressure hydraulic system comprises the hydraulic pressure cycling mechanism and is passed into the oil spout mechanism of the oil pocket of each rail unit.
The oil pipe of each rail unit of feeding that described oil spout mechanism comprises multi-head pump, link to each other with multi-head pump, the oil duct that communicates with the oil pocket of each rail unit on the base, described multi-head pump and base are affixed.
Described hydraulic pressure cycling mechanism comprises the ring-type oil-recovery tank that has spill port on the pumping plant of workbench rotating disk side, the oil sump of containing oil and the base, and the oil of the ring-type oil-recovery tank of base flow back into oil sump during duty.
The quantity of described rail unit is 12.
The rotary table device of the utility model double column vertical lathes adopts such structure, on base, have a plurality of uniform in the form of a ring rail units, each rail unit has the oil pocket in guide pass and the guide pass zone, by multi-head pump to the quantitative fuel feeding of each oil pocket, after feeding in the oil pocket of rail unit has the lubricating oil of certain pressure intensity, workbench is lifted slightly, and between the guide pass of rail unit, be full of fluid formation oil film, make the base rail face be in the neat liquid Frotteurism.When lathe starts and process the weight part, owing to directly do not contact all the time between workbench rotating disk and the base rail, and under the good fluid pressure of adjusted, evenly float, have good kinematic accuracy and bigger load resistant power so can guarantee workbench, prolonged the service life of base rail.
