Description
Technical field
The utility model relates to a kind of table device of chain digital control gear hobbing machine.
Background technology
Traditional chain digital control gear hobbing machine adopts single turbine, in working angles, there is all the time certain gap, along with the increase gap of wearing and tearing is increasing, cutting precision also will decline thereupon, also have that workbench calibration auxiliary air gap is excessive must readjust problem to worm gear pair gap simultaneously.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of work top calibration secondary gapless processing, and steadily, cutting precision is high in cutting, the table device of the chain digital control gear hobbing machine that the secondary precision stability of calibration is good.
For achieving the above object, the technical solution of the utility model is: a kind of table device of chain digital control gear hobbing machine, comprise work top, the center of described work top is penetrated with a pull bar, one end of described pull bar is socketed with a holder, this holder and work top interference fit, the other end of pull bar is socketed with the second holder, on the other end of pull bar, be also provided with a rotating clamp locking oil cylinder, the middle outer ring sleeve of described pull bar is connected to an axle sleeve, the second holder and axle sleeve are bolted to connection, the outer ring sleeve of described axle sleeve is connected to twin worm worm gear, the outer ring sleeve of described twin worm worm gear is connected to workbench housing, between described workbench housing and axle sleeve, be also provided with bearing, described twin worm worm gear comprises indexing worm and damping worm screw, the two ends of described damping worm screw are respectively provided with a damping oil cylinder.
The beneficial effects of the utility model are: indexing worm transfer motion power wherein, guarantee the accurate high-speed motion of dividing movement, damping worm screw is by the active force of two axial damping oil cylinders, make damping worm screw mobile to the rightabout trace of turbine rotation, guarantee that worm screw turbine is all the time among tight mesh, thereby reached the secondary gapless processing of work top calibration, eliminated again in cutting process and shaken steadily phenomenon because gap produces, improved dynamic stiffiness and cutting precision; Due to twin worm worm gear reason, even after worm gear wearing and tearing, still keep zero-clearance processing simultaneously, without readjusting worm gear gap because of wearing and tearing, make the secondary precision stability of calibration good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of indexing worm of the present utility model;
Fig. 3 is the structural representation of damping worm screw of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.
As shown in Figure 1 to Figure 3, the table device of a kind of chain digital control gear hobbing machine of the utility model, comprise work top 1, the center of described work top 1 is penetrated with a pull bar 2, one end of described pull bar 2 is socketed with a holder 3, this holder 3 and work top 1 interference fit, the other end of pull bar 2 is socketed with the second holder 4, on the other end of pull bar 2, be also provided with a rotating clamp locking oil cylinder 5, the middle outer ring sleeve of described pull bar 2 is connected to an axle sleeve 6, the second holder 4 is bolted to connection with axle sleeve 6, the outer ring sleeve of described axle sleeve 6 is connected to twin worm worm gear 7, the outer ring sleeve of described twin worm worm gear 7 is connected to workbench housing 8, between described workbench housing 8 and axle sleeve 6, be also provided with bearing 9, described twin worm worm gear 7 comprises indexing worm 71 and damping worm screw 72, the two ends of described damping worm screw 72 are respectively provided with a damping oil cylinder 73.
Indexing worm 71 transfer motion powers wherein, guarantee the accurate high-speed motion of dividing movement, damping worm screw 72 is by the active force of two axial damping oil cylinders 73, make damping worm screw 72 mobile to the rightabout trace of worm gear rotation, guarantee that worm and wormwheel is all the time among tight mesh, thereby reached the secondary gapless processing of work top calibration, eliminated again in cutting process and shaken steadily phenomenon because gap produces, improved dynamic stiffiness and cutting precision; Due to twin worm worm gear reason, even after worm gear wearing and tearing, still keep zero-clearance processing simultaneously, without readjusting worm gear gap because of wearing and tearing, make the secondary precision stability of calibration good.
