A kind of tilted back type crossbeam gantry line rail ray machine
Technical field
The utility model relates to a kind of machine tooling equipment, particularly a kind of tilted back type crossbeam gantry line rail ray machine.
Background technology
Fixed-beam gantry line rail ray machine adopts decides the beam gantry frame structure; The rigidity foot; In being applicable to, the grinding of large-scale workpiece; Workpiece can directly be fixed on the work top, and its structure is made up of base, workbench, left and right pillar, crossbeam, main shaft, X axle, Y axle and Z axis rail and driving control device thereof.Behind the part by one-step clamping, can accomplish mill, multiple operation processing such as brill, boring, be applicable to thick, the fine finishining of the large and medium-sized part of every profession and trade.
In the existing machine tool, have following shortcoming: crossbeam adopts cuboid box structure, and main shaft is arranged at crossbeam the place ahead, misalignment crossbeam center, main shaft receive moment big, poor stability.
The utility model content
The purpose of the utility model is to adopt cuboid box structure to existing gantry line rail ray machine crossbeam, and main shaft is arranged at crossbeam the place ahead, misalignment crossbeam center; Main shaft receive moment big, the deficiency of poor stability provides a kind of tilted back type crossbeam gantry line rail ray machine; The crossbeam of this gantry line rail ray machine adopts the tilted back type structure; More near the crossbeam center, stability promotes the alignment of shafts greatly, has the ability of heavy cut.
In order to solve above-mentioned prior art problem, the technical scheme of the utility model is:
A kind of tilted back type crossbeam of the utility model gantry line rail ray machine comprises base, workbench, left and right pillar, crossbeam, main shaft, X axle, Y axle and Z axis rail and driving control device thereof.
The whole box-structure that adopts of said crossbeam;
As improvement, the tilted back type structure is adopted in said crossbeam front, and the crossbeam front is shaped to the guide pass at certain inclination angle, and said guide pass is provided with three-way rail, and is provided with in the crossbeam and is used for two firm cross bars;
Said main shaft is the inclined-plane of coupling beam guideway face at the back, and said beam guideway face slides and is provided with a plurality of slide blocks, and main shaft is connected in the beam guideway face through slide block, and said slide block adopts square structure.
The beneficial effect of a kind of tilted back type crossbeam of the utility model gantry line rail ray machine has: crossbeam adopts the tilted back type structure, and the alignment of shafts is more near the crossbeam center, and what make main shaft receives moment littler, and stability promotes greatly, has the ability of heavy cut.
Description of drawings
Fig. 1 is the stereogram of the utility model one embodiment;
Fig. 2 is the sketch map of the tilted back type structure of the crossbeam of Fig. 1 embodiment;
The specific embodiment
1-2 is described further the utility model below in conjunction with accompanying drawing:
A kind of tilted back type crossbeam of the utility model gantry line rail ray machine comprises base 1, workbench 2, column 3, crossbeam 4, main shaft 5, X axle, Y axle and Z axis rail and driving control device thereof.
The said crossbeam 4 whole box-structures that adopt;
As improvement, the tilted back type structure is adopted in said crossbeam front, and the crossbeam front is shaped to the guide pass 41 at certain inclination angle, and said guide pass is provided with three-way rail 42, and is provided with in the crossbeam and is used for two firm cross bars;
Said main shaft is the inclined-plane of coupling beam guideway face at the back, and said beam guideway face slides and is provided with a plurality of slide blocks 43, and main shaft is connected in the beam guideway face through slide block, and said slide block adopts square structure.
The crossbeam of this gantry line rail ray machine adopts the tilted back type structure, and the alignment of shafts is more near the crossbeam center, and what make main shaft receives moment littler, and stability promotes greatly, has the ability of heavy cut.
Below the utility model is done a detailed description; The above is merely the preferred embodiment of the utility model, when not limiting the utility model practical range; Be allly to do impartial change and modify, all should still belong in the utility model covering scope according to the application's scope.
