The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Figure 1-4, in the utility model to bit platform, comprise base plate 1, landing slab 2, mobile device and dry type electromagnetic brake 4; Described mobile device comprises transmission device 32 and supporting device 31, described supporting device 31 is comprised of supported end 311 and the cross guide rail under it, and described cross guide rail is by upper rail 312, form with the lower guideway 314 of upper rail right-angled intersection and the intermediate slider 313 being slidably connected between upper and lower guide rail; Described supported end 311 upper ends are fixedly connected with landing slab 2, and lower end is fixedly connected with corresponding upper rail 314; Described lower guideway 314 is fixed on base plate 1; On described transmission device fixed base plate 1, described transmission device 32 driving sections are connected on intermediate slider 313; Described transmission device 32 at least comprises 3, and has a transmission direction at least perpendicular to other two; Described supporting device 31 is 4, is separately positioned on described workbench diagonal, and described transmission device is electronic screw rod transmission or chain drive.Described dry type electromagnetic brake 4 comprises fixed disk 401, magnet ring 402, electromagnetism portion 403 and base 404, described magnet ring 402 is fixedly connected with fixed disk 401, described fixed disk 401 upper ends are fixed on workbench 2, lower end is corresponding with electromagnetism portion 403, and described dry type electromagnetic brake 4 fixed disk 401 lower ends and electromagnetism portion 403 upper end distances are 0.2mm.Described dry type electromagnetic brake 4 comprises 4, is arranged at respectively on described workbench center line.Described electromagnetism portion 403 is fixedly connected with base 404, and described base 404 is fixed on base plate 1.
To laterally be made as X-axis to bit platform, and longitudinally be made as Y-axis, be θ direction along platform center.During use, under the effect of transmission device 32, drive supporting device 31 to move simultaneously, and indirectly make landing slab 2 do the movement of X, Y, tri-directions of θ.While moving to the position of OK Deng landing slab 2,4 energisings of dry type electromagnetic brake, magnet ring 402 because strong magnetic force attracts, guarantees that whole mechanism, without displacement phenomenon, has directly guaranteed printing precision with electromagnetism portion 403.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
