Abstract
The utility model relates to a horizontal beam, in particular to a numerical control moving beam gantry machine tool super-wide horizontal beam which comprises a numerical control moving beam gantry machine tool super-wide horizontal beam body. A left stand column, a right stand column, a horizontal beam body, a ram and a dragging plate are included. The left stand column is fixed at the left end of the horizontal beam body. The right stand column is fixed at the right end of the horizontal beam body. The ram is placed in the dragging plate which is movably connected to the horizontal beam body. The horizontal beam body is fixedly provided with an unloading beam which is placed between the horizontal beam body and the dragging body. An eccentric unloading mechanism is fixed on the dragging plate which is movably connected with the horizontal beam body through the eccentric unloading mechanism. The horizontal beam body transmits the weight of the dragging plate and a ram part to the stand columns at the two ends through the unloading beam arranged on a moving beam, the problem of horizontal beam body addition down warping caused by the fact that the ram part moves on the horizontal beam body is solved, cost is saved, and the efficacy is improved.
Description
Technical field
The utility model relates to a kind of crossbeam, especially the super wide beam of numerical control movable beam gantry lathe.
Background technology
The at present moving super wide beam of beam gantry, when planker moves to cross girder middle part, can, because weight issue makes cross girder produce downwarp, thereby has influence on the result of use of lathe, shorten its service life.
Utility model content
The deficiency of downwarp easily occurs in order to overcome existing crossbeam, and the utility model provides numerical control movable beam gantry lathe super wide beam.
The utility model solves the technical scheme that its technical problem adopts: the super wide beam of numerical control movable beam gantry lathe, comprise left column, right column, cross girder, ram and planker, left column is fixed on cross girder left end, right column is fixed on cross girder right-hand member, ram is placed in planker, planker is movably connected on cross girder, on cross girder, be fixed with Unloading Beam, Unloading Beam is placed between cross girder and planker, eccentric unloading mechanism is fixed on planker, and planker is flexibly connected with cross girder by eccentric unloading mechanism.
According to another embodiment of the present utility model, further comprise that eccentric unloading mechanism forms by adjusting screw, big roller, eccentric shaft, butterfly spring and sleeve, sleeve top is provided with adjustment screw, and inside is provided with butterfly spring, and bottom is connected with big roller by eccentric shaft.
According to another embodiment of the present utility model, further comprise that the guide rail middle part of cross girder makes the pre-treatment of convexity.
The beneficial effects of the utility model are, this crossbeam by be arranged on Unloading Beam on moving beam by the weight transmitting of planker and ram parts to two ends column, and pass through the pre-protruding solution of Unloading Beam by planker, ram parts cause the problem of the additional downwarp of cross girder while moving on cross girder, save cost, improved effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
Fig. 2 is cutaway view of the present utility model;
Fig. 3 is the schematic diagram of eccentric unloading mechanism;
1. left columns in figure, 2. right column, 3. cross girder, 4. ram, 5. planker, 6. Unloading Beam, 7. eccentric unloading mechanism, 71. adjust screws, 72. big rollers, 73. eccentric shafts, 74. butterfly springs, 75. sleeves.
The specific embodiment
If Fig. 1 is front view of the present utility model, Fig. 2 is cutaway view of the present utility model, Fig. 3 is the schematic diagram of eccentric unloading mechanism, the super wide beam of numerical control movable beam gantry lathe, comprise left column 1, right column 2, cross girder 3, ram 4 and planker 5, left column 1 is fixed on cross girder 3 left ends, right column 2 is fixed on cross girder 3 right-hand members, ram 4 is placed in planker 5, planker 5 is movably connected on cross girder 3, on cross girder 3, be fixed with Unloading Beam 6, Unloading Beam 6 is placed between cross girder 3 and planker 5, eccentric unloading mechanism 7 is fixed on planker 5, planker 5 is flexibly connected with cross girder 3 by eccentric unloading mechanism 7, eccentric unloading mechanism 7 is by adjusting screw 71, big roller 72, eccentric shaft 73, butterfly spring 74 and sleeve 75 form, sleeve 75 tops are provided with adjusts screw 71, inside is provided with butterfly spring 74, bottom is connected with big roller 72 by eccentric shaft 73, the pre-treatment of convexity is made at the guide rail middle part of cross girder 3.
Be arranged on the eccentric unloading mechanism 7 on planker 5, by disk spring 74, apply a moment of torsion to eccentric shaft 73, thereby eccentric one end of eccentric shaft 73 is pressed down, and roll on Unloading Beam 6 below the big roller 72 of these eccentric shaft 73 eccentric segments is forced to be pressed in, the weight of planker 5 and ram 4 parts is passed to the off-load that left column 1 and right column 2 have been realized Y-direction moving-member by Unloading Beam 6, the adjustment of off-load power is without reconditioning pad, as long as adjust, be added in the adjustment screw 71 on dish spring, this cross girder by be arranged on Unloading Beam 6 on moving beam by the weight transmitting of planker 5 and ram 4 parts to two ends column, and pass through the pre-protruding solution of Unloading Beam 6 by planker 5, ram 4 parts cause the problem of cross girder 3 additional downwarps while moving on cross girder 3, saved cost, improved effect.
