Summary of the invention
The purpose of this utility model is to overcome above deficiency, provides the lifting mechanism that a kind of positioning precision is high, operate steadily.
The purpose of this utility model is achieved through the following technical solutions: a kind of lifting mechanism, comprise two columns be arranged side by side, be connected by supporting seat between two root posts, supporting seat is provided with two linear bearing permanent seats placed side by side, linear bearing is equipped with in each linear bearing permanent seat, linear bearing is connected with guide pillar, the top of guide pillar is connected with axle center permanent seat, two axle center permanent seats are connected with Lifting platform jointly, position between two guide pillars is provided with extenal fixation seat to supporting seat, multiple bearing is provided with in extenal fixation seat, bearing is connected with internal fixtion seat, internal fixtion cover for seat is on nut, run through in nut and be provided with screw rod, the position that screw rod is positioned at extenal fixation seat top is provided with driven timing wheel, driven timing wheel is connected with active timing wheel by belt, initiatively timing wheel is connected with motor reducer, motor reducer is fixed on motor fixing base, the top of screw rod is connected with Lifting platform by Connection Block.
Further improvement of the utility model is: be provided with about two bearings placed in described extenal fixation seat.
Further improvement of the utility model is: described bearing is tapered roller bearing.
The utility model compared with prior art has the following advantages: structure is simple, and easy to use, the features such as positioning precision is high, stable action, save oil pressure unit, avoid oil pollution.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1-column, 2-supporting seat, 3-linear bearing permanent seat, 4-linear bearing, 5-guide pillar, 6-axle center permanent seat, 7-Lifting platform, 8-extenal fixation seat, 9-tapered roller bearing, 10-internal fixtion seat, 11-nut, 12-screw rod, the driven timing wheel of 13-, 14-be timing wheel, 15-motor reducer, 16 motor fixing bases initiatively.
detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to the utility model protection domain.
As Fig. 1 shows the detailed description of the invention of a kind of lifting mechanism of the utility model, comprise two columns be arranged side by side 1, be connected by supporting seat 2 between two root posts 1, supporting seat 2 is provided with two linear bearing permanent seats 3 placed side by side, linear bearing 4 is equipped with in each linear bearing permanent seat 3, linear bearing 4 is connected with guide pillar 5, the top of guide pillar 5 is connected with axle center permanent seat 6, two axle center permanent seats 6 are connected with Lifting platform 7 jointly, position between two guide pillars 5 is provided with extenal fixation seat 8 to supporting seat 2, multiple bearing 9 is provided with in extenal fixation seat 8, bearing 9 is connected with internal fixtion seat 10, internal fixtion seat 10 is enclosed within nut 11, run through in nut 11 and be provided with screw rod 12, the position that screw rod 12 is positioned at extenal fixation seat 8 top is provided with driven timing wheel 13, driven timing wheel 13 is connected with active timing wheel 14 by belt, initiatively timing wheel 14 is connected with motor reducer 15, motor reducer 15 is fixed on motor fixing base 16, the top of screw rod 12 is connected with Lifting platform 7 by Connection Block, about two bearings placed 9 are provided with in the preferred extenal fixation seat 8 of the utility model, bearing 9 is tapered roller bearing.
Lifting mechanism described in the utility model, by utilizing the fixing rotation of nut 12, makes screw rod 11 be elevated.Internal fixtion seat 10 is connected with nut 11, tapered roller bearing 9 on the outer cover of internal fixtion seat 10, then extenal fixation seat 8 entangles tapered roller bearing 9, the Internal and external cycle of this tapered roller bearing at present is all locked, again upper tapered roller bearing is put into extenal fixation seat, topmost to be connected with internal fixtion seat by driven timing wheel and to push down upper tapered roller bearing inner ring, namely whole group of structure be elevated by motor driving realization.This kind of lifting structure has positioning precision high relative to hydraulic elevating platform, and the features such as stable action, save oil pressure unit, avoid oil pollution.
