The left end surface of the lug boss is provided with a lower guide rail. The lower guide rail is arrangedon the lug boss in such a mode that the lower guide rail is vertical with the upper guide rail. The upper part of the Y-axis slide carriage is matched with the upper guide rail in a sliding mode. Andthe lower part of the Y-axis slide carriage is matched with the lower guide rail in a sliding mode. The utility model can improve sensitivity, rigidity, anti-vibration property, load capacity and anti-bending capacity of the guide mechanism and the processing equipment kinematic pair.
Description
Technical field
The utility model relates to the Machining Technology field, is specifically related to numerical control gantry lathe beam composite guide rail.
Background technology
The planer type numerical control lathe of machinery manufacturing industry extensive use at present.Numerous categories such as gantry machine tool is contained and decided beam, moving beam, and move at movable workbench, gantry, overhead crossbeam moves.Crossbeam is the critical component of planer type numerical control lathe, the dynamic property of the whole lathe of whether reasonable directly influence of this structure and the machining accuracy of part, and machining accuracy influences the principal element of the range of application of lathe just.
The crossbeam of traditional form is generally upper and lower two guide rails, and two linear guides have parallel horizontal in a plane; Have and be dislocation shape parallel horizontal on two planes; 30 ° of parallel horizontal that are in tilted layout in a plane are arranged into.More than like this bilinearity guide rail makes that the main shaft of the main spindle box installed on the Y-axis planker is big apart from the guide pass distance, and when heavy cut, after main shaft was stressed, it was big to produce turning torque, had reduced the rigidity and the machining accuracy of lathe.
Summary of the invention
The purpose of this utility model provides a kind of numerical control gantry lathe beam composite guide rail, and the utility model can improve sensitivity, rigidity, antivibration power, load force and the bending resistance square ability of guiding machinery and process equipment kinematic pair.
The technical scheme that realizes the utility model purpose is as follows:
Numerical control gantry lathe beam composite guide rail, comprise Y-axis slide carriage and crossbeam, the crossbeam upper surface is provided with upper rail, the crossbeam lower left side is provided with lug boss, the left side of this lug boss is provided with lower guideway, lower guideway is arranged on the lug boss in the mode perpendicular to upper rail, and the top and the upper rail of Y-axis slide carriage are slidingly matched, and the bottom of Y-axis slide carriage and lower guideway are slidingly matched.
Adopted such scheme, be provided with lug boss in the crossbeam lower left side, the left side of this lug boss is provided with lower guideway, lower guideway is arranged on the lug boss in the mode perpendicular to upper rail, it is poor to have formed a ladder between upper rail and the lower guideway, makes in the machine tooling process, and the position of centre of gravity of Y-axis slide carriage is pressed close to the top, the distance of the alignment of shafts line-spacing beam guideway face that is connected with the Y-axis slide carriage is shortened, thereby improved the rigidity and the machining accuracy of numerical control gantry machine tool crossbeam.Make the center of gravity of main spindle box shift to crossbeam, rigidity increases, and the turning torque when working to reduce main shaft helps improving the stability of machine tooling and the precision of part to be processed.In addition, the function that upper rail and lower guideway are born guiding, off-load and born live load, and strengthen vibration resistance, rigidity and operating load ability, improve sensitivity, rigidity, antivibration power, load force and the bending resistance square ability of guiding machinery and process equipment kinematic pair greatly.
The Y-axis slide carriage is provided with the panel device that is positioned at top, lug boss upper surface, and the upper surface of this panel device and lug boss is slidingly matched.The weight of Y-axis slide carriage is acted on the crossbeam by the panel face, guarantee the precision long-term stability of guide rail, guarantee the machining accuracy of lathe.
The lug boss lower surface is provided with flange, and a pressing plate that contacts with this flange side is fixedly connected on the Y-axis slide carriage.Pressing plate has further been eliminated the active force of cutting force to guide rail with after crossbeam cooperates, and has improved the precision long-term stability of guide rail.
In sum, beam guideway composite construction of the present utility model, turning torque is little, rapid dynamic response speed, nothing is creeped, and can guarantee that machine tool capability is reliable.In the dynamic property that improves whole lathe, also will improve the machining accuracy of part.
