Abstract
The utility model provides a high-precision lifting device which is connected with an electric machine. The high-precision lifting device comprises a sliding plate, a steel ball belt, a lead screw, a stand column and a screw nut block, wherein the lead screw is fixed on the stand column, the screw nut block is fixed on the sliding plate, the screw nut block is matched with the lead screw, the steel ball belt is arranged between the sliding plate and the stand column, and the electric machine is connected with the lead screw. The steel ball belt is embedded with a steel ball to replace a guide rail retainer, so that the rolling slide is realized, and the friction is greatly reduced; the steel ball is high in quality, intensity and precision, and is precisely selected, so that the high-precision requirement of the motion of the sliding plate is guaranteed, and the stability of the lifting motion is further greatly improved.
Description
Technical field
The utility model relates to a kind of highi degree of accuracy lowering or hoisting gear.
Background technique
The lowering or hoisting gear of prior art generally adopts traditional V-type rail, and what adopt between guide rail that has and the guide rail is that plastic cement is protected support, and low precision catching phenomenon can occur during rapid movement; Suddenly quicken or amplitude is big when stopping, stationarity is lower, high-level straightness accuracy, parallelism are difficult to guarantee that working time, long more wearing and tearing were severe more, the most important thing is that precision also changes thereupon, were difficult to satisfy work requirements.
The model utility content
The technical problems to be solved in the utility model provides a kind of convenient, fast, high-precision lowering or hoisting gear.The utility model is achieved through the following technical solutions:
A kind of highi degree of accuracy lowering or hoisting gear of the present utility model is connected with motor, comprises slide plate, steel ball band, leading screw, column and screw piece; Wherein, leading screw is fixed on the column, and the screw piece is fixed on the slide plate, and the screw piece matches with leading screw, and described steel ball band is placed between slide plate and the column, and described motor connects leading screw.
As preferably, two row's steel ball bands about being provided with between described slide plate and the column.
A kind of highi degree of accuracy lowering or hoisting gear of the present utility model, adopting the steel ball band to inlay steel ball replaces guide rail to protect support, the bigger friction that reduced of sliding realizes rolling, what our steel ball adopted simultaneously is the high-precision steel ball of high quality high strength, all be chosen from a hundred, guarantee the high-precision requirement of skateboarding, also improved the stationarity of elevating movement simultaneously greatly.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the three-dimensional combination figure of the utility model highi degree of accuracy lowering or hoisting gear;
Fig. 2 is the plan view of the utility model highi degree of accuracy lowering or hoisting gear.
Embodiment
A kind of highi degree of accuracy lowering or hoisting gear of the present utility model, be connected with motor, as depicted in figs. 1 and 2, comprise slide plate 1, steel ball band 2, leading screw 3, column 4 and screw piece (not shown), leading screw 3 is fixed on the column 4, the screw piece is fixed on the slide plate 1, and the screw piece matches with leading screw 3, and steel ball band 2 then is placed between slide plate 1 and the column 4, by 3 rotations of driven by motor leading screw, the screw piece moves forwards or backwards, and seesaws thereby drive slide plate 1, realizes lifting moving.Solve problems such as existing lowering or hoisting gear stability is not high, motion clamping stagnation, amplitude is big, slip is not steady, and kinematic accuracy is lower.In the present embodiment, be provided with between described slide plate 1 and the column 4 about two row's steel ball bands 2.
The utility model adopts the steel ball band to inlay steel ball replacement guide rail and protects support, the bigger friction that reduced of sliding realizes rolling, what our steel ball adopted simultaneously is the high-precision steel ball of high quality high strength, all be chosen from a hundred, guarantee the high-precision requirement of skateboarding, also improved the stationarity of elevating movement simultaneously greatly.
The foregoing description is an instantiation of the present utility model, is not to be used for limiting the utility model interest field, and all equivalences of doing according to the utility model change and modify, and all should be included in the patent claimed range of the present utility model.
Claims (2)
1. a highi degree of accuracy lowering or hoisting gear is connected with motor, it is characterized in that: comprise slide plate, steel ball band, leading screw, column and screw piece; Wherein, leading screw is fixed on the column, and the screw piece is fixed on the slide plate, and the screw piece matches with leading screw, and described steel ball band is placed between slide plate and the column, and described motor connects leading screw.
2. a kind of highi degree of accuracy lowering or hoisting gear according to claim 1 is characterized in that: two row's steel ball bands about being provided with between described slide plate and the column.
