Description
Technical field
The present invention relates to guide assembly, refer more particularly to a kind of linear rail assembly.
Background technique
The linear rail assembly is widely used in the various mechanical production devices such as numerical control machine tool.Traditional linear rail assembly, its structure generally includes: guide rail and a pair of slider that is symmetricly set on guide rail, the guide surface of guide rail is flat face, slider mainly is made of slide block and the pulley that is arranged on the guide block guide surface.The disadvantage of this guidance set is that surface friction drag is large, serious wear, and working life is short; And the excesssive gap between pulley and guide rail is too small all can cause the operation of guide assembly not smooth, thereby makes the installation of guide assembly very difficult.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of easy for installation, and can reduce the linear rail assembly of surface friction drag.
for solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of linear rail assembly, comprise: guide rail and a pair of activity are symmetricly set on the slider on guide rail, described guide rail comprises: guide rail, guide rail line of travel along slider on its both sides guide surface is symmetrically arranged with the lug boss that the cross section is circular arc, each slider comprises: sliding mount and a pair of slide block that is symmetricly set in sliding mount, offer a pair of along its line of travel on the guide surface of slide block, connect the circular arc direction recess of its two ends end face, the circumference circle of this direction recess is not less than 3/5ths of full circle girth, slide block is respectively arranged with cover plate at the two ends of its direction recess notch, form the direction recess of a pair of closed at both ends, this is to all being placed with several guiding steel balls in direction recess, these both sides to the symmetrical lug boss that is arranged in guide rail of rolling of the steel ball in direction recess, the both sides of described sliding mount are equipped with respectively at least one pair of horizontal adjustment bolt and at least one pair of vertical adjusting bolt by tapped hole, horizontal adjustment bolt be used for adjusting slider with the perpendicular substantially horizontal position of its glide direction, the vertical adjusting bolt be used for adjusting slider with the perpendicular Vertical direction position of its glide direction.
Line of travel along slider on the guide surface of described guide rail offers circular arc arrangement groove, settles in groove and is provided with directional post.
3/5ths of the circumference circle of the arrangement groove of described guide rail 〉=full circle girth.
Be provided with positioning groove on the bottom surface of described guide rail.
The invention has the beneficial effects as follows: in the present invention, steel ball in slide block is that point contacts with the lug boss of guide rail, and, steel ball can be done the rotation of any direction, thereby greatly reduce the surface friction drag between slider and guide rail, and the gap between guide rail and slider is adjusted by vertical adjusting bolt and horizontal adjustment bolt, greatly facilitates the installation of guide assembly.In addition, because the circumference circle of settling groove and direction recess all is not less than 3/5ths of all place full circle girths separately of its week, having guaranteed that steel ball and directional post can and not settled groove from the direction recess at place separately comes off, and has guaranteed the normal use of described linear rail assembly.
