Description
Technical field
The present invention relates to rail mounted guide field, the guiding device of track that a kind of precision is high.
Background technology
In prior art, it is a kind of conventional guidance mode that rail mounted guides, for guiding the motion of slide unit.The concrete structure of guide rail has upper prominent formula and concave etc..For upper prominent formula guide rail, due to its planform, it is difficult in adapt under some occasions that the aspect without protruding is had requirement.Concave guide rail is widely used under some occasions having flatness requirement for compactedness and the profile of equipment.But, this concave guide rail, due to its recessed structure, is therefore easily subject to environmental contaminants and enters and pollute thing accumulation, and this has the impact in terms of precision particularly with the guider of precise motion.And it safeguards inconvenience, give and use and all bring adverse effect equipment life.
These unfavorable aspects can be avoided by arranging buffer zone.But, owing to being embedded in the impact of the sliding part in indent guide-track groove, the width of buffer zone is narrower than the width of guide-track groove, the most still can leave gap thus be difficult to avoid the entrance of pollutant at all.
Summary of the invention
It is an object of the invention to the guiding device of track that a kind of precision is high, it can overcome defect of the prior art.
nullAccording to the guiding device of track that a kind of precision of the present invention is high，Including rail guide piece and be slidably matched with described rail guide piece and in order to slide unit be connected slide unit pedestal，Described rail guide piece includes having upper side wall and base wall thus limits the housing in the sliding chamber of guide rail betwixt，Described slide unit pedestal has and is matched with being slidably engaged seat and being connected with described sliding engagement seat one and the connecting neck portion that protruded upward by the guide rail cannelure in described upper side wall is in order to connected with described slide unit of the sliding intracavity of described guide rail，Described upper side wall is extended with buffer zone locating flange on the direction towards described guide rail cannelure，In order to carry out spacing with extending longitudinally in the spring protective band portion crossover closed in described guide rail cannelure and for chamber sliding to described guide rail，The upper surface middle part of described spring protective band is provided with and is embedded in the protuberance between two described buffer zone locating flanges for card so that the upper surface of described rail guide piece forms integral planar，Described sliding engagement seat is provided with the via cavities passed for described spring protective band，It is provided with near the upper side position of described via cavities and is installed on the down-pressure roller on the downside of described connecting neck portion in order to engage with the upper side of described protuberance，So that the pressurized position of the upper side of described protuberance is positioned under the upper side of described via cavities，Deformation on longitudinal direction occurs described spring protective band due to pressing down of down-pressure roller thus the upper side edge of described spring protective band and described buffer zone locating flange gradually disengage and pass described via cavities；nullWherein，Protrusion shielding plate it is additionally provided with on the left and right sides of described connecting neck portion，The longitudinal extent (L) of described protrusion shielding plate is longer than the longitudinal size (L) of described slide unit pedestal，So that the crushed element on the longitudinal direction of described spring protective band is blocked，It is equipped with flexible cavity in described protrusion shielding plate both sides，It is provided with spacing lip at described flexible cavity outer ledge，It is provided with the flexible slide block of sliding connection in described flexible cavity and is fixed on the pneumatic cylinder of described flexible cavity medial end，Described flexible slide block is fixed with telescopic baffle near described spacing lip side，And with described spacing lip sliding connection，Described flexible slide block opposite side is fixed with expansion link，Described expansion link opposite side is connected with described pneumatic cylinder，Stretch out such that it is able to control described pneumatic cylinder stretching into of described telescopic baffle of regulation according to actual needs，Described sliding engagement seat bottom portion is provided with roller，Described roller is provided with four and is directional wheel，Described roller is separately positioned on the right and left in described sliding engagement seat bottom portion with each two one group，Described roller causes abrasion in order to reduce described sliding engagement seat and described base wall to slide for a long time，Improve service life.
By the present invention, owing to the slide head of sliding part is provided with, there is the through hole passed for elastic buffer zone, therefore, it is possible to make can be non-interference in motor function between the slip of sliding part and the setting of buffer zone.Spring protective band is pressed on the downside of less than the roof of direction recess by the roller being installed on described slide head by setting, even if thus at the installed position of sliding part, the width of buffer zone remains able to the cannelure width of rebate being wider than at the upper opening of gathering sill, it is possible to the width so that whole piece buffer zone be all wider than this longitudinal notch thus realize integrity close.And the fin extension of sliding part cervical region both sides it is fixed on by setting, it is possible on bigger longitudinal length, hide the buffer zone deformation occurred due to adjacent slides so that the probability that pollutant enter on the upside of the buffer zone of deformation inside guide groove reduces.By being arranged on the projecting surface on buffer zone upper side, it is possible to embed between defining flange, thus shape makes the upper side of guide have smooth plane in consistent manner, it is to avoid pollutant accumulate on and are difficult to clean off in re-entrant angle or gap.
