Abstract
The utility model discloses a kind of Longmen machine tool crossbeam relief arrangement, Longmen machine tool crossbeam installs relief arrangement, this relief arrangement is made up of arch floor stringer and hydraulic jack, arch floor stringer two ends are secured by bolts in upper end, cross beam support position, hydraulic jack is provided with between crossbeam and arch floor stringer, the oil cylinder end of hydraulic jack schedules on floor stringer by hinges fixing, the tailpiece of the piston rod of hydraulic jack schedules crossbeam upper end by hinges fixing, the changing value of crossbeam linearity when moving on crossbeam by measuring moving slide board, adjustment enters the hydraulic fluid pressure of hydraulic jack respectively, the tailpiece of the piston rod of hydraulic jack is moved up different distances, drive crossbeam upwards reversible deformation, finally reach moving slide board can ensure the linearity of crossbeam object when crossbeam optional position.The utility model arranges relief arrangement on Longmen machine tool crossbeam, the deflection of Longmen machine tool crossbeam can be adjusted, improve the geometric accuracy of lathe, adjust easy, stable and reliable for performance.
Description
Technical field
The utility model belongs to machining equipment technical field, is specifically related to a kind of Longmen machine tool crossbeam relief arrangement.
Background technology
At present, gantry machine tool is progressively to large-scale, ultra-large type future development, and crossbeam span is increasing, causes crossbeam to produce flexural deformation because of moving-member weight change on own wt and crossbeam and is difficult to effectively overcome, directly affect the geometric accuracy of lathe.In order to improve the ability of machine tool beam resistance to deformation, usually adopting and the method for off-load is carried out to eliminate beam deformation to crossbeam.Existing crossbeam unloading-structure all can not adjust, if Theoretical Design and actual conditions have deviation, a whole set of unloading-structure needs to make larger adjustment, wastes time and energy, poor operability, complex structure.Therefore need to improve existing Longmen machine tool relief arrangement, Longmen machine tool beam deformation amount can be adjusted, thus ensure the linearity of crossbeam, improve geometric precision of machine tool.
Utility model content
The purpose of this utility model is to provide a kind of Longmen machine tool crossbeam relief arrangement, can adjust Longmen machine tool beam deformation amount, thus ensures the linearity of crossbeam, and improve geometric precision of machine tool, wide accommodation, adjusts easy, stable and reliable for performance.
The technical solution of the utility model is:
The utility model installs relief arrangement on Longmen machine tool crossbeam, and relief arrangement is made up of arch floor stringer and hydraulic jack, and arch floor stringer two ends are secured by bolts in the upper end at cross beam support position, are provided with hydraulic jack between crossbeam and arch floor stringer.
The oil cylinder end of hydraulic jack is by hinges fixing on floor stringer, and the tailpiece of the piston rod of hydraulic jack schedules crossbeam upper end by hinges fixing.
The number of hydraulic jack is 1-13.
The changing value of crossbeam linearity when the utility model moves on crossbeam by measuring moving slide board, adjustment enters the hydraulic fluid pressure of hydraulic jack respectively, the tailpiece of the piston rod of hydraulic jack is moved up different distances, drive crossbeam upwards reversible deformation, finally reach moving slide board can ensure the linearity of crossbeam object when crossbeam optional position.
The utility model compared with prior art has following beneficial effect:
The utility model installs relief arrangement on Longmen machine tool crossbeam, can adjust Longmen machine tool beam deformation amount, thus ensures the linearity of crossbeam, and improve geometric precision of machine tool, wide accommodation, adjusts easy, stable and reliable for performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1, crossbeam, 2, arch floor stringer, 3, hydraulic jack, 4, moving slide board.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model installs relief arrangement on Longmen machine tool crossbeam 1, relief arrangement is made up of arch floor stringer 2 and hydraulic jack 3, and arch floor stringer 2 two ends are secured by bolts in the upper end of crossbeam 1 support zone, are provided with hydraulic jack 3 between crossbeam 1 and arch floor stringer 2.
The oil cylinder end of hydraulic jack 3 is by hinges fixing on arch floor stringer 2, and the tailpiece of the piston rod of hydraulic jack 3 schedules crossbeam 1 upper end by hinges fixing.
The number of hydraulic jack 3 is 1-13.
The changing value of crossbeam 1 linearity when the utility model moves on crossbeam 1 by measuring moving slide board 4, adjustment enters the hydraulic fluid pressure of hydraulic jack 3 respectively, the tailpiece of the piston rod of hydraulic jack 3 is moved up different distances, drive crossbeam 1 upwards reversible deformation, finally reach moving slide board 4 can ensure the linearity of crossbeam 1 object when crossbeam optional position.
In sum, the utility model can adjust Longmen machine tool beam deformation amount, thus ensures the linearity of crossbeam, and improve geometric precision of machine tool, wide accommodation, adjusts easy, stable and reliable for performance.
