Description
Technical Field
The utility model relates to a guide rail technical field specifically is an airtight linear guide.
Background
The linear guide rail is a common guide mechanism at present, and comprises a guide rail, a sliding block and rolling bodies, wherein the sliding block moves on the guide rail relatively, the rolling bodies roll in grooves on two sides of the guide rail in a circulating manner, and the cleaning degree of the rolling bodies and the grooves plays a key role in the overall performance of the linear guide rail. The current linear guide adopts a physical passive protection mode by adding a scraping blade and the like, and the mode has the following two insurmountable defects:
the scraping blade is in physical contact with the guide rail, so that the friction force between the sliding block and the guide rail is increased, and the protection is tight; friction can bring heat, influence the guide rail precision.
In addition, the rolling elements are balls, gaps are reserved among the balls, harmful foreign matters such as fine dust, water mist and the like can enter the rolling elements and grooves frequently, rolling failure and rusting are caused, and the precision and the service life of the guide rail are adversely affected after long-time use.
Disclosure of Invention
In order to solve the problem that foreign matters such as dust easily get into in the current linear guide influence guide rail precision and life, the utility model provides an air-tight linear guide, it can prevent effectively that harmful foreign matters such as micronic dust and water smoke from getting into, increases guide rail life, and the protection cost is low when improving the guide rail precision.
The technical scheme is as follows: the air-tight seal linear guide rail is characterized in that an air inlet hole is formed in the outer surface of the rolling body installation cavity, an air path communicated with the air inlet hole is formed in the rolling body installation cavity, the air path outlet faces to a gap between the rolling bodies, and the air inlet hole is connected with a compressed air source.
The guide rail is further characterized in that an organ protective cover is arranged outside the guide rail body.
Adopt the utility model discloses afterwards, continuously input compressed gas from the inlet port, guarantee that the gas circuit in the rolling element installation cavity forms the normal pressure, continuously have the gas to blow off in the rolling element clearance, foreign matters such as dust can't get into, do not have the physical contact that the physics protection brought, reduced the frictional force between guide rail and the slider, reduced the thermal production of slider operation period, improved the guide rail precision, increased guide rail life, the protection is with low costs.
Drawings
FIG. 1 is a front view of the structure of the present invention;
fig. 2 is a side view of the present invention.
Detailed Description
See fig. 1, as shown in fig. 2, an airtight linear guide rail comprises a guide rail body 1, a sliding block 2 is arranged on the guide rail body 1, a rolling element installation cavity 3 is arranged on the sliding block 2, groove-matched rolling elements on two sides of the guide rail body 1 are installed in the rolling element installation cavity 3, air inlets 4 are formed in the outer surface of the rolling element installation cavity 3, air passages 5 communicated with the air inlets 4 are formed in the rolling element installation cavity 3, the outlet of the air passages 5 faces to the gap between the rolling elements, the air inlets 4 are connected with a compressed air source, and the compressed air source continuously supplies air inwards.
The guide rail body 1 is externally provided with an organ protective cover, so that the protective effect can be further achieved.
Claims (2)
