A kind of fixed-beam gantry line rail ray machine that improves the base line rail
Technical field
The utility model relates to a kind of machine tooling equipment, particularly a kind of fixed-beam gantry line rail ray machine that improves the base line rail.
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, its structure is made up of base, workbench, left and right pillar, crossbeam, 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: fixed-beam gantry line rail ray machine base rail is few, and the degree of balance is poor; And the base inner supporting structure is simple; Lifting capacity is not enough, and poor rigidity adds man-hour because machine cut power and mobile inertia are bigger at heavy cut; Machine tool accuracy and stability are difficult to guarantee, directly influence target localization and machining accuracy.
The utility model content
The purpose of the utility model is few to existing fixed-beam gantry line rail ray machine base rail, and the degree of balance is poor, and the base inner supporting structure is simple; Lifting capacity is not enough, and the shortcoming of poor rigidity provides a kind of fixed-beam gantry line rail ray machine that improves the base line rail; It adopts many guiderail bases, and promptly base is furnished with 3,4 branch line rails, and inner rib overstriking, adds; Significantly promote the lathe lifting capacity, the base good rigidly, positioning accuracy is high.
In order to solve above-mentioned prior art problem, the technical scheme of the utility model is:
A kind of fixed-beam gantry line rail ray machine that improves the base line rail of the utility model comprises that base, workbench, left and right pillar, crossbeam, X axle, Y axle and Z axis rail and driving control device thereof constitute.
As improvement, be furnished with 3,4 branch line rails on the said base, said line rail is horizontally disposed with, be parallel to each other at interval, and line rail coupling has corresponding slide block to connect with workbench, makes supporting point more.
As improvement, base inside is provided with many group reinforcing rib structures corresponding to every line rail below, and said reinforcing rib structure vertically is certain distance at interval, and reinforcing rib structure is made up of three reinforcements, becomes three downward forked types, and said reinforcement adopts the rib of overstriking.
A kind of beneficial effect that improves fixed-beam gantry line rail ray machine of base line rail of the utility model has: adopt many guiderail bases; Be that base is furnished with 3,4 branch line rails, and inner rib overstriking, add, significantly promote the lathe lifting capacity; The base good rigidly, positioning accuracy is high.

The specific embodiment
1-2 is described further the utility model below in conjunction with accompanying drawing:
A kind of fixed-beam gantry line rail ray machine that improves the base line rail of the utility model comprises base 1, workbench 2, and left and right pillar 3,4, crossbeam 5, X axle, Y axle and Z axis rail and driving control device thereof constitute.
Be furnished with many branch lines rail 11 on the base 1 of this fixed-beam gantry line rail ray machine, said line rail is horizontally disposed with, be parallel to each other at interval, and line rail coupling has corresponding slide block to connect with workbench, makes supporting point more.
The base inside of this fixed-beam gantry line rail ray machine is provided with many group reinforcing rib structures 12 corresponding to every line rail below; Said reinforcing rib structure vertically is certain distance at interval; Reinforcing rib structure is made up of three reinforcement 12a, and said reinforcement becomes three downward forked types, adopts the rib of overstriking.
Embodiment as shown in Figure 1 is furnished with 3 branch line rails on this fixed-beam gantry line rail ray machine base.
Embodiment as shown in Figure 2 is furnished with 4 branch line rails on this fixed-beam gantry line rail ray machine base.
The utility model is a kind of to improve fixed-beam gantry line rail ray machine of base line rail owing to adopt many guiderail bases, and inner rib overstriking, adds, and the lathe lifting capacity is good, the base good rigidly, and positioning accuracy is high.
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.
