Utility model content
Height is required for the processing technique and packaging technology lifting guide pin bushing (nut) present in prior art, the technical problem that the cost that causes is high, the purpose of this utility model is the worktable lifting structure providing a kind of nut to rotate, have employed reversely use, be applied in the jacking systems such as planing machine platen.
The technical solution adopted in the utility model is:
The worktable lifting structure that a kind of nut rotates, including workbench, mounting flange, leading screw, thrust ball bearing, deep groove ball bearing, nut, sprocket wheel, round nut, protective jacket, thicknesser platform flange, plug, workbench is connected with leading screw by thicknesser platform flange, leading screw and nut connect, the lateral wall of nut is set to zigzag structure, sprocket wheel is connected with nut by key, the bottom of sprocket wheel is fixed by round nut, mounting flange it is provided with between sprocket wheel and nut, mounting flange uses the dual bearing structure that a thrust ball bearing and a deep groove ball bearing match, thrust bearing and nut, mounting flange radial fit, deep groove ball bearing and nut, mounting flange axially engages, ensure that nut can bear the top-down pressure of workbench while flexible rotating, nut rotates under the drive of sprocket wheel, power is passed on leading screw.
Further, the outside of described leading screw is provided with protective jacket, and plug is set to conehead anti-loose structure.
Further, the bottom of described protective jacket is provided with plug.
Further, the counteracting force of workbench is passed on body by described thrust ball bearing.
Further, the upper end of described thrust ball bearing is provided with lubricating cup, stores lubricating oil in lubricating cup.
Further, described mounting flange is provided with support thrust ball bearing and the boss structure of deep groove ball bearing.
Further, the external diameter of described thrust ball bearing is bigger than the external diameter of deep groove ball bearing.
The beneficial effects of the utility model are:
This utility model uses the novel elevating system of lead screw transmission principle, is applied in the jacking systems such as planing machine platen, and power passes on nut by sprocket wheel, nut rotation, leading screw moves along a straight line up and down, thus drives workbench to move up and down, and uses contrary with conventional gear principle.So nut only needs a bit of coupling part, and size is less, reduces for difficulty from the point of view of processing, and cost reduces by 50%, assembles and becomes simple, and this utilization has passed through checking on Novel planer, and has great market application foreground.
The thrust ball bearing used in this utility model and nut, the mode of mounting flange radial fit, the lifting pressure of workbench all can be delivered on body by mounting flange, reduce nut and the precision of mounting flange, material requirements, improve the service life of nut and mounting flange.
The mode that the dual bearing structure that this utility model uses a thrust ball bearing and deep groove ball bearing to match connects, make nut operating more steady, rapid operation, improve lifting efficiency, fixing by the oil lubrication in lubricating cup and mounting flange, makes rotating part operating more steady.
Protective jacket and plug in this utility model can prevent wood flour and dust etc. from entering jacking system, extend the service life of jacking system.Thrust ball bearing is can to pass on body by the counteracting force of workbench, has been achieved in that the elevating movement that workbench needs, has been effectively saved manpower.
