Abstract
The invention discloses a high precision lifting device which is connected with a motor and comprises a slide plate, a steel ball belt, a lead screw, an upright column and a nut block, wherein the lead screw is fixed on the upright column, the nut block is fixed on the slide plate and is matched with the lead screw, the steel ball belt is arranged between the slide plate and the upright column, and the motor is connected with the lead screw. In the invention, the steel ball belt inlaid with a steel ball is adopted to replace a bracket protected by a guide rail to realize rolling sliding so that the friction is greatly reduced, and the adopted steel ball also has high quality, strong strength and high precision and is one in hundred, thereby the high precision requirements on the motion of the slide plate are met and the stability of lifting motion is greatly improved at the same time.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of convenient, fast, high-precision lowering or hoisting gear.The present invention is achieved through the following technical solutions:
A kind of highi degree of accuracy lowering or hoisting gear of the present invention 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 invention, 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 present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the three-dimensional combination figure of highi degree of accuracy lowering or hoisting gear of the present invention;
Fig. 2 is the plan view of highi degree of accuracy lowering or hoisting gear of the present invention.
Embodiment
A kind of highi degree of accuracy lowering or hoisting gear of the present invention, 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 present invention 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, just example of the present invention is not to be used for limiting interest field of the present invention, and is all according to equivalence variation and modification that the present invention did, all should be included in the patent claimed range of the present invention.
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.
