Abstract
The present invention relates to an air knife type linear sliding rail, particularly to the lifting of dust prevention technology of the linear sliding rail. The dust prevention does not passively prevent foreign bodies from entering the internal part of a sliding block any longer, and furthermore, the dust prevention adopts to initiatively remove the foreign bodies. The present invention makes the dust prevention way of the linear sliding rail lifted to be a dust prevention way; the dust prevention efficiency of the linear sliding rail of the present invention is greatly increased, and the service life of the linear sliding rail is prolonged. Since the combined circumference of the sliding block has air jet and dust removal efficiency, the linear sliding rail can be applied to working environment with severe contamination; the applied range of the linear sliding rail is wide, and the competitive power of the products is greatly lifted.
Description
Technical field
The invention relates to a kind of air knife type linear sliding rail, refer in particular to a kind of lifting of dust control technology of linear slide rail, become a kind of linear slide rail that can remove the dedusting method of foreign material on one's own initiative, especially be fit to the linear slide rail in woodworking machinery, stone material cutting and the contour dust environment for use of textile industry.
Background technology
Traditional linear slide rail as shown in Figure 7, wherein comprise slide rail 10, slide block 20, end cap 30, lid 7b, rolling element 5b and oil-scrapping sheet 40, and end cap 30, lid 7b and oil-scrapping sheet 40 are locked on the slide block 20 with screw 6b, on slide rail 10 and the slide block 20 the pearl groove is arranged all, rolling element 5b then places between slide block 20 pearl grooves and the slide rail 10 pearl grooves and makes circulating rolling, and the frictional resistance that is produced when slide block 20 is relatively moved on slide rail 10 is less.The both sides of slide block 20 respectively have an end cap 30 that rolling element 5b is turned to, when slide block 20 is mobile on slide rail 10, rolling element 5b is by the return port (not marking) that enters slide block 20 between the pearl groove of slide block 20 and slide rail 10 through end cap 30, enter the end cap 30 of the other end by return port again and get back in the pearl groove of slide block 20 and slide rail 10, so rolling element 5b can make unlimited shuttling movement.Because the circulating path of this rolling element 5b can be got dirty or destroys because of entering of impurity, so oil-scrapping sheet 40 is set in slide block 2
The outside of 0 both sides end cap 30 avoids the foreign material on the slide rail 10 to enter in the rolling element 5b circulating path of slide rail 10 and slide block 20, to reach the dustproof effect.
Linear slide rail has been widely used in precision optical machinery and general industrial machine at present, so linear slide rail requires to have more and more high trend to dustproof.But the dust control technology of linear slide rail but still rests on and stops foreign material to enter the stage of slide block inside at present, that is uses oil-scrapping sheet to enter slide block inside with the foreign material that stop the slide rail surface.The dustproof efficient of this kind mode is leaned on the adaptation of the appearance profile of oil-scrapping sheet and slide rail fully, if oil-scrapping sheet and slide rail are excessively to closely cooperate then to influence the precompression of linear slide rail, and oil-scrapping sheet may be because of wearing and tearing fast, the very fast function that stops foreign material to enter slide block that promptly loses; On the other hand, if do not closely cooperate between oil-scrapping sheet and the slide rail, then it can only stop foreign material bigger on the slide rail surface, make bigger foreign material not enter slide block inside, but for less impurity even dust etc. just not too have dustproof effect, so the impurity dust still enters the slide block internal contamination even destroys the circulating path of rolling element, and the service life of reducing linear slide rail, also therefore the range of application of linear slide rail is restricted widely.
In sum, real necessity that has improvement to progress greatly of above-mentioned known technology.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of air knife type linear sliding rail, it is dedusting method that its dust control technology with linear slide rail is promoted by dustproof mode, make that the applicable scope of linear slide rail is more extensive, and can prolong the service life of linear slide rail and the competitiveness of lifting linear slide rail.
A kind of air knife type linear sliding rail of the present invention is characterized in that, comprises at least:
One slide rail is the rectangular of a finite length, and the both side surface of slide rail has the strip pearl groove parallel with slide rail;
One sliding shoe combination cooperates with aforesaid slide rail and slides on slide rail, and has the pearl groove that cooperates with aforesaid slide rail pearl groove in it, and is provided with the return-flow system of rolling element; This sliding shoe combination comprises that a slide block, two end cap, two oil-scrapping sheets, two air guide blocks and two cover plates combine, and wherein respectively there are two fixing holes on air guide block both sides, and air guide block and cover plate are combined closely; And the both sides of air guide block respectively are provided with an air-flow introducing port;
Most rolling elements places between the pearl groove of aforesaid slide rail and sliding shoe combination;
One air chamber is a space, and it is inner to be located at aforesaid sliding shoe combination;
Wherein the combination of this slide rail and sliding shoe and place between the two rolling element and the combination of the air chamber of an air-guiding, be that air is imported air chamber, air is outwards sprayed from the inboard profile along the slide rail external form of sliding shoe combination, and reaches the effect of dedusting.
Wherein said air chamber is to be arranged in the enclosure space of air guide block.
Wherein said cover plate is the outside of being located at the air guide block.
Cover plate wherein can be the metal material manufacturing and forms.
Because present linear slide rail is applied in general industrial machine quite widely and is subjected to precision mechanically, it must overcome some problems when using, and dustproof one of the subject matter wherein that is.
Air knife type linear sliding rail of the present invention changes the dust control technology of linear slide rail the mode of the dirty dirt of positive removal slide rail surface impurity into by the mode that the dirty dirt of impurity enters the slide block body of preventing of passiveness.The present invention uses the principle of air-flow, air is imported the air chamber of sliding shoe combination, utilize wind path that pressure air is sprayed along the slide rail profile outward from the inboard of sliding shoe combination, gas blowout can be removed the dirty dirt of impurity on slide rail surface in advance thus, before the sliding shoe combination was passed through, the dirty dirt of the impurity on slide rail surface had promptly been sprayed by air-flow and has removed.
So the present invention will known dustproof mode is prevented that by lower level the dirty dirt of impurity from entering slide block and promoting to removing slide rail surface impurity dirt dirt on one's own initiative, the slide rail surface that allows the sliding shoe combination be passed through is the slide rail surface of the dirty dirt of free from admixture, this moment, nature just need not be considered the problem that the dirty dirt of impurity can enter the slide block body, make the not contaminated or destruction of the rolling element circulatory system of slide block inside, to prolong the service life of linear slide rail, and can allow linear slide rail be applied to pollute than serious environmental, but and then make the range of application of linear slide rail more extensive, so the competitiveness of linear slide rail can promote widely.
