Embodiment 1
[0031] like image 3 as shown, image 3 Yes figure 2 The cross-sectional side view of the magnetic levitation guide shown in this embodiment, in this embodiment, it can not only provide a stable large-size magnetic levitation working air gap to meet the needs of a frictionless guide rail with a larger stroke, but also can be adjusted arbitrarily like an air flotation system The base air gap thickness even turns off the magnetic levitation function.
[0032] In this structure, the stator 20 has a plurality of sliding grooves, and the mover 10 floats and slides in the sliding grooves, and the sliding grooves are formed by steel guide rails 1-103, 1-103a, 1-103b. Therefore, it can be understood that when the mover 10 floats on the surface of the stator 20 , the mover 10 has a plurality of tooth-shaped structures protruding into the sliding slots to match the surface shape of the stator 20 . In this embodiment, the mover 10 is the slider frame 1-104. The stator 20 also includ...
Embodiment 2
[0042] like Figure 8 As shown, in this embodiment, 3-101 is an oblique magnetized magnet installed on both sides of the V-shaped groove-shaped guide rail, and its function is similar to that of magnetized magnets 1-101 and 1-102a in Embodiment 1, 1-102b; 3-105 is the rotatable magnet embedded in the slide block, its effect is similar to the rotatable magnet 1-105a, 1-105b in embodiment one; 3-106a, 3-106b is the horizontal stiffness magnet, its effect Similar to the horizontal stiffness magnets 1-106a, 1-106b in Example 1; 3-109a, 3-109b are RX-direction stiffness magnets, which make the RX direction have stiffness, so that the slider cannot be arbitrarily deflected or moved along the X-direction. Can only deflect in a small range.
[0043] In this embodiment, the magnetized magnetic steel is magnetized obliquely compared with the first embodiment, and the horizontal stiffness magnet is located at the bottom of the sliding groove. It can be seen that the present invention d...
