The high anti-dust performance structure of described linear guide pairs, is characterized in that: it is to make substrate with steel plate that the two kiss of this end face lip is scraped bits plate, outer side surface composite elastic high-abrasive material.
The high anti-dust performance structure of described linear guide pairs, is characterized in that: the both sides, front and back of this slide block movement direction are all provided with end casing, and the two kiss of this end face lip is scraped bits plate and is arranged on end casing.
The high anti-dust performance structure of described linear guide pairs, it is characterized in that: this roller holder comprises a metal top retainer and each metal side retainer of left and right, on this metal top retainer and metal side retainer, all there is fixed installation hole, by fixed block and fixed installation hole, coordinate metal top retainer and metal side retainer) be fixed on slide block.
The high anti-dust performance structure of described linear guide pairs, is characterized in that: on this guide rail, have guide rail fixed hole, on this guide rail fixed hole, add and be stamped compound dust cover, form gapless plane coordinate after this compound dust cover closes with guide rail top; This compound dust cover is engineering plastics.
The invention has the advantages that:
1, linear guide pairs of the present invention have that kinematic accuracy is high, sport efficiency is high, without sideshake, without creeping, the advantage such as rigidity is strong, low noise and long lifetime.
2, the present invention is simple in structure, part is few, and unfailing performance is high, and during use, the impact of climate temperature is less, can in poor working environment, can work reliably.
3, the end face in the present invention is scraped bits plate and is had the two kiss of the resilient end face of steel backing complex abrasion-proof lips and scrape bits plate, can guarantee that slide block has a reliable working environment in orbit, and whole linear guide pairs has extended service precision and life-span.
4, the combined metal roller holder in the present invention with respect to existing plastics roller holder there is easy to assembly, long service life, the advantage such as be difficult for falling apart.
5, the dust cover in the present invention coordinates with guide rail top gapless after closing, and overcomes the problem of aperture Integrated Chip

Embodiment
Refer to Fig. 1-9, the invention discloses a kind of high anti-dust performance structure of linear guide pairs.As Figure 1-4: it comprises guide rail 1, be arranged on guide rail 1 and the slide block 2 that can slide on guide rail 1, be arranged on rolling element 3 and roller holder between guide rail 1 and slide block 2.In addition, can also be equipped with oil nozzle (not shown).Feature of the present invention is: the both sides, front and back of these slide block 2 moving direction are all provided with the two kiss of the end face lips that elastic abrasion-proof material makes and scrape bits plate 5, the two kiss of this end face lip is scraped on bits plate 5 to be had corresponding to two kiss lips of guide rail profile and scrapes bits hole 51, the aperture that this pair of kiss lip scraped bits hole 51 is two kiss lips 52, and two kiss lips 52 are the outside latch bolt structure of the tip of the tongue.
During use, along with sliding on guide rail 1, slide block 2 also can drive the two kiss of end face lip to scrape bits plate 5 to slide on guide rail 1.When the two kiss of end face lip is scraped bits plate 5 and moved laterally, the tip of the tongue of two kiss lips 52 (outside latch bolt structure) can sweep and release guide rail 1 by the dust on guide rail 1 or pollutant; When end face is scraped bits plate 5 while moving to the inside, the tip of the tongue of two kiss lips 52 is owing to having adopted elastic material, therefore can stride across dust or the pollutant on guide rail 1, avoid these objects to be brought in slide block 2, avoid the risk that service precision reduces and reduce working life causing thus.
As a kind of preferred structure, it is to make substrate with steel plate that the two kiss of this end face lip is scraped bits plate 5, outer side surface composite elastic high-abrasive material.The both sides, front and back of these slide block 2 moving direction are all provided with end casing 6, and the two kiss of this end face lip is scraped bits plate 5 and is arranged on end casing 6.
As shown in Fig. 1,2,5-8: this roller holder comprises a metal top retainer 41 and each metal side retainer 42 of left and right, on this metal top retainer 41 and metal side retainer 42, all there is fixed installation hole, by fixed block and fixed installation hole, coordinate metal top retainer 41 and metal side retainer 42 are fixed on slide block 2.The roller holder that adopts said structure with respect to existing bakelite material roller holder there is easy to assembly, long service life, the advantage such as be difficult for falling apart.
As shown in Fig. 1,9, on this guide rail 1, there is guide rail fixed hole 11, on this guide rail fixed hole 11, add the dust cover 7 that is stamped high hardness, after closing, this dust cover 7 coordinates with guide rail top gapless, overcome the problem of aperture Integrated Chip.
Be only preferred embodiment of the present invention in sum, be not used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application the scope of the claims change and modify, all should be technology category of the present invention.
