Abstract
The utility model relates to the structure of an operating platform for a large-scale numerical control gear hobbing machine, which is especially applicable to the technical field of large-scale numerical control gear hobbing machining machine tools. The main structure is as follows: a centering main shaft of the operating platform is arranged in the middle of horizontal guide rails, pressure oil feeding channels and unloading oil cavities the oil of which is supplied by a single oil pump station are arranged on the guide rails, and an indexing worm wheel installed on the operating platform is connected with a high-accuracy indexing worm and a worm bracket. In the utility model, as a hydrostatic bearing of the centering main shaft of the operating platform is adopted for centering, the rigidity of radial rotation of the operating platform can be ensured; and the horizontal guide rails are hydrostatic unloading guide rails, and the unloading pressure thereof can be adjusted according to the load of the operating platform. The structure of the operating platform for the large-scale numerical control gear hobbing machine has the characteristics of reasonable structure, low manufacturing cost, convenient adjustment and installation, and the like, and can well solve the problem of centering rigidity of the operating platform of the large-scale numerical control gear hobbing machine.
Description
Technical field
The utility model belongs to the heavy-duty gear machine industry, is particularly useful for the technical field of large-sized numerical control gear hobbing machining tool, is the Working table structure of large-sized numerical control gear-hobbing machine.
Background technology
The large-sized numerical control gear-hobbing machine is in the processing use, because processing work weight is heavier, diameter of work is bigger, so the damping of workbench calibration is bigger when this type of part of processing, causes the workbench vibration easily, finally influences the workpiece machining accuracy.Therefore, large-sized numerical control gear hobbing platen stability of transmission and centering rigidity are the keys that ensures the workpiece machining accuracy.Alleviate the mode foot employing cone bearing and the rolling bearing centering usually of this type of problem in the prior art, but effect still not very desirable.
Summary of the invention
The purpose of this utility model is at deficiency of the prior art, proposes a kind of large-sized numerical control gear hobbing machine worktable structure that is applicable to, to reduce to add the vibration of workbench in man-hour, ensures the machining accuracy of processing equipment job stability and raising gear.
The said large-sized numerical control gear hobbing machine worktable of the utility model structure, the frame mode of employing hydrostatic bearing and horizontal guide rail.Its workbench centering main shaft is placed in the middle of the horizontal guide rail, and workbench centering main shaft adopts hydrostatic bearing, guarantees radially rotational stiffness of workbench; The horizontal guide rail of workbench is a unloaded slideway, on the horizontal guide rail of circle, be provided with the off-load oil pocket that adopts independent oil pump station fuel feeding, and pressure oil oil supply gallery, can operate steadily under the workbench heavy duty guaranteeing, the workpiece machining accuracy is stable, and the size of its pressure unloading can be regulated according to the magnitude of load of workbench.In addition, precision round subsection worm gear, worm gear pair transmission are adopted in the driving of the said large-sized numerical control gear hobbing machine worktable of the utility model, and the dividing worm wheel that promptly is placed on the workbench is connected mutually with precision round subsection worm screw and endless screw support.
The utlity model has rational in infrastructurely, low cost of manufacture is adjusted characteristics such as easy for installation, and the centering hydrostatic bearing project organization of especially sufficient workbench is simple, and is easily manufactured, can solve the centering rigidity problem of large-sized numerical control gear hobbing machine worktable preferably.
Description of drawings
Accompanying drawing 1: large-sized numerical control gear hobbing machine worktable structure is implemented schematic diagram.
The specific embodiment
Accompanying drawing 1 is that the said large-sized numerical control gear hobbing machine worktable of the utility model structure is implemented schematic diagram.Comprise compositions such as dividing worm wheel 5, indexing worm and endless screw support 6, workbench centering main shaft 1, horizontal guide rail 2.It constitutes, workbench centering main shaft 1 is placed in the middle of the horizontal guide rail 2, on the horizontal guide rail 2 of circle, be provided with the off-load oil pocket 3 that adopts independent oil pump station fuel feeding, and pressure oil oil supply gallery 4, the dividing worm wheel 5 that is placed on the workbench is connected mutually with precision round subsection worm screw and endless screw support 6.
Adopt the hydrostatic bearing centering of workbench centering main shaft, can guarantee radially rotational stiffness of workbench; Horizontal guide rail adopts the static pressure unloaded slideway, and the big I of its pressure unloading is regulated according to the magnitude of load of workbench.
