Embodiment Construction

[0020] Such as figure 1 , figure 2 The high-precision and large-size motion platform shown includes a motion platform body 1, a slide rail assembly, a drive system 2, and a basic bed 3. Several slide rail assemblies are mounted on the base bed 3, and the slide rail assembly is equipped with The motion platform body 1 is connected with a drive system 2 on at least one slide rail, and its special feature is that the slide rail assembly is composed of at least two linear slide rails 4 that run perpendicular to each other and are in the shape of a "cross" . Of course, in order to facilitate the stable connection between the slide rail assembly and the moving platform body 1 , the moving platform body 1 is distributed with connecting bosses 5 connected with the linear sliding rail 4 .

[0021] further combined figure 2 From the point of view, in order to facilitate the linear slide rails 4 to release the expansion or contraction of the motion platform body 1 due to temperature...

Abstract

The invention relates to a high-precision large-size motion platform which comprises a motion platform body, sliding rail assemblies, a driving system and a basic lathe bed, wherein a plurality of sliding rail assemblies are mounted on a basic lathe bed; the motion platform body is added on the sliding rail assemblies; and at least one sliding rail assembly is connected with the driving system. The motion platform is characterized in that each sliding rail assembly at least comprises two mutually vertical linear sliding rails with the trends in a cross shape, thus the limit influences of the size of the motion platform can be eliminated. When the size of the body of the motion platform is greatly increased, effective guiding and supporting are realized through increasing guide sliding rails so as to avoid adverse phenomena such as deflection, and the like. Even if the size of the body of the motion platform is too large to cause thermal deformation, the thermal deformation can be released through the linear sliding rails with left and right trends, and the flatness of the platform cannot be influenced.

Description

technical field [0001] The invention relates to a motion platform, in particular to a high-precision large-size motion platform. Background technique [0002] The processing platform is the processing basis of the machine tool. The size of the platform determines the processing capacity and efficiency of the machine tool, especially for multi-station machine tools, the increase of stations means that the size of the platform needs to be increased. Therefore, the large-size processing platform is a key step in the leap forward of the processing capacity of the processing machine tool. [0003] However, the contradiction is that the precision requirements of machine tools are getting higher and higher, which limits the size of the motion platform. Because the size is too large, it will bring unfavorable factors such as deflection and crawling. When the size of the bed is large, the two guide rails on both sides of the drive system alone cannot guide and support the platform...
