CN201521615U - Dustproof chip scrapping plate of rolling linear guide rail pair - Google Patents

Abstract

The utility model discloses a dustproof chip scrapping plate of a rolling linear guide rail pair, which is a rectangular thin rubber plate with an opening at one edge, wherein the shape of the opening is similar to the edge shape of the guide rail cross section of the guide rail pair, the cross section shape of the edge of the opening is an outwards extending tongue shape, and the tongue top extends out of the plane of the thin plate. The dustproof chip scrapping plate is arranged at both ends of a slide block of the rolling linear guide rail pair, and the tongue top outwards extending at the edge of the opening maintains the elastic contact with the guide rail surface. When the slide block moves on the guide rails, the tongue top of the dustproof chip scrapping plate removes impurities attached on the surface of the guide rail. In addition, the dustproof chip scrapping plate has the blockage effect on suspended impurities no mater the slide block is in a movable state or a static state, and the utility model has the dustproof effect. The utility model has the advantages that the dustproof chip scrapping plate of the rolling linear guide rail pair integrates the dust prevention and chip scrapping into a whole body, the structure is simple, and the installation is convenient.

Description

The dustproof bits plate of scraping of linear rolling guide

Technical field

The utility model belongs to an annex of linear rolling guide, and what be specifically related to is that a kind of impurity such as dust that prevent enter the dustproof bits plate of scraping of linear rolling guide inside.

Background technique

Linear rolling guide more and more widely be applied to the various working occasion.In the occasion that has, dust is many, and these dust are attached to the surface of rolling linear guide easily, and slide block is easy to carry it into guiding pairs inside in movement process, and when serious, slide block can be stuck, and causes the moving system paralysis.Although the slide block two ends of linear rolling guide are equipped with dust guard in the prior art, but they only can stop unsteady impurity such as dust and iron filings and directly enter from the gap of raceway and slide block, and to not having the removing function attached to the impurity on the raceway face.Therefore, linear rolling guide often is subjected to the restriction of some operating mode occasions.

The model utility content

The purpose of this utility model is to overcome in the prior art can not remove the defective that raceway face is adhered to impurity, provide a kind of linear rolling guide the dustproof bits plate of scraping, it can prevent dust, and can will fall attached to the contaminant removal on the raceway, keep the guide rail cleaning, make linear rolling guide can be applied to various work condition environments.

The technological scheme that realizes above-mentioned purpose is: the dustproof bits plate of scraping of a kind of linear rolling guide, it is the rectangular rubber sheet of an openings at one side, opening shape is similar to the guide rail section edge shape of guiding pairs, the section configuration on opening edge edge is overhanging tongue shape, and the lip of the tongue stretches out the plane of thin plate.

Should dustproof scrape and consider the slide block two ends that plate is installed in linear rolling guide to be worth doing, opening edge keeps and the slideway Elastic Contact along the overhanging the tip of the tongue.When slide block moves on guide rail, the dustproof the tip of the tongue of scraping the bits plate just will be rooted out attached to the impurity of guide rail surface.And no matter slide block is in dynamically or static state, and this is scraped the bits plate and all the impurity that suspends is intercepted, and has dustproof effect.

The utility model collection prevents dust and scrapes bits and is one, simple structure, easy for installation.

Description of drawings

Fig. 1 is an embodiment's of the utility model a front shape schematic representation.

Fig. 2 is the left view of Fig. 1.

Fig. 3 is the worm's eye view of Fig. 1.

Among the figure: 1. dustproof bits board substrate, 2. opening edge edge, 3. slide block, the 4. guide rail scraped.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

The dustproof bits board substrate 1 of scraping of the utility model is the rectangular rubber sheet of openings at one side, the guide rail section edge shape similar (as shown in Figure 1) of opening shape and guiding pairs, opening edge is overhanging tongue shape (as shown in Figure 4) along 2 section configuration, and tongue shape opening edge stretches out the plane (as shown in Figures 2 and 3) of thin plate along the lip of the tongue of 2.In the present embodiment, tongue shape opening edge is 25 ° along 2 the tip of the tongue angles, the positive angle with slideway of tongue is 20 °, and this shape and state can keep the dustproof bits plate opening edge of scraping contact with the slideway better elastic with preferable scraping along the tip of the tongue and consider effect (as shown in Figure 4) to be worth doing.

Claims (2)

1. a linear rolling guide prevents dust and scrapes the bits plate, it is characterized in that: it is the rectangular rubber sheet of an openings at one side, opening shape is similar to the guide rail section edge shape of guiding pairs, and the section configuration on opening edge edge is overhanging tongue shape, and the lip of the tongue stretches out the plane of thin plate.

2. scrape the bits plate according to described the preventing dust of claim 1, it is characterized in that: described tongue shape opening edge is 25 ° along the tip of the tongue angle, and the positive angle with slideway of tongue is 20 °.
