The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Shown in Fig. 1-7, the present invention relates to a kind of novel beam gantry pentahedron R beam structure of deciding, comprise cross-beam body 1, described cross-beam body 1 internal placement muscle structure, comprise perpendicular muscle 12, horizontal bar 9, cross bar 14, around muscle 8, the left side wall 10 of described cross-beam body 1 and right flank 11 are parallel with perpendicular muscle 12, the front face 2 of described cross-beam body 1 is connected with rear surface and is connected respectively horizontal bar 9 two ends, the front face 2 of described cross-beam body 1 arranges lower guideway installation position 7 on the lower, the upper wall surface 4 forward ends of described cross-beam body 1 arrange upper rail installation position 6, the lower end of described cross-beam body 1 is lower wall surface 5, the front face 2 of described cross-beam body 1 is hierarchic structure, front face 2 one ends of described cross-beam body 1 are arranged leading screw bearing sedimentation platform 16, spindle motor sedimentation platform 17 is arranged in the opposite end, described leading screw bearing sedimentation platform 16 and spindle motor sedimentation platform 17 are arranged on the same straight line, the front face 2 of described cross-beam body 1 is primary load bearing face, wall thickness 40mm, the upper wall surface 4 of described cross-beam body 1, lower wall surface 5, left side wall 10, the wall thickness of right flank 11 is 30mm, the wall thickness of the rear surface 3 of described cross-beam body 1 is 20mm, described cross bar 14 is arranged in cross-beam body 1) on the medial surface of each wall, described upper rail installation position 6 to the distance of front face 2 is the layout size of upper rail installation position 6, size is 50mm, described horizontal bar 9 is perpendicular to several perpendicular muscle 12 that is evenly arranged, and adjacent perpendicular muscle 12 is separated into two laterally zygomorphic display units 13, arrange cross bar 14 in the described display unit 13, described horizontal bar 9 is arranged square hole 15 in laterally zygomorphic two display units 13, described perpendicular muscle 12 is arranged circular hole 19 in each display unit 13, the rear surface 3 of described cross-beam body 1 is arranged husky hole 18 in the position of display unit 13 correspondences of inside.
Because upper rail is installed in the upper rail installation position 6 of cross-beam body 1 upper wall surface 4 front ends, lower guideway is installed in cross-beam body 1 front face 2 lower guideway installation position 7 on the lower, and the saddle ram parts that are assemblied in cross-beam body 1 are used in masterpiece on the crossbeam by upper rail and lower guideway.Owing to requiring upper rail to bear saddle ram parts overall weight in the design; again because there is the arm of force in saddle ram parts with respect to crossbeam; crossbeam had torsional interaction; so upper rail is also born the horizontal force that the torsional interaction of saddle ram parts generation causes; lower guideway is born the horizontal force of the torsional interaction of saddle ram parts generation; novel cross-beam is original with span type HTM-30GR crossbeam relatively with sea day Seiko; novel cross-beam has promoted 61.1% in anti-bending strength, also has greatly improved on the torsional property.Aspect moving rigidity, the intrinsic frequency of novel cross-beam has also promoted 14%.Can find out by Fig. 6 and Fig. 7, the saddle ram is respectively on old crossbeam and the beam deformation situation in novel cross-beam when motion, from two forms, can find, the deformation values of novel cross-beam is obviously little and change relatively mild, upper/lower guide deformation values curve does not intersect yet, and good stability provides guarantee to the precision improvement of lathe, the reliability of precision also greatly promotes simultaneously, has promoted the quality of lathe.High rigid beam is conducive to mach yield rate, and the percent of pass of lathe machine tool accuracy after the crossbeam assembling, greatly reduces crossbeam linearity rework rate and manufacturing cost, reduction lathe debugging cycle.
