Specific embodiment
The present embodiment provides a kind of crossbeams that pillar numerical control gantry is moved suitable for large span, are installed on the vertical of numerical control gantry
On column.As shown in Figures 1 to 4, numerical control gantry crossbeam includes cross-beam body 1 and adjustment component.Cross-beam body 1 is top and bottom
The domes of intermediate arc-shaped protrusion, 1 bottom of cross-beam body are respectively arranged on the left side and the right side acclivitous arcuate surface 2,
The top and bottom of cross-beam body 1 are domes, prevent cross-beam body sagging because of gravity, while enhancing cross-beam body
Rigidity.Adjusting component includes fixed block 3, pull rod 4 and locking nut 5, and two fixed blocks 3 are respectively arranged on two arcuate surfaces 2,
Be equipped with the through-hole 7 passed through for pull rod 4 in two fixed blocks 3, the left and right ends of pull rod 4 stretch out respectively after two through-holes 7 with lock
Tight nut 5 is threadedly coupled, and the left and right ends of 5 tensile ties 4 of locking nut and abuts fixed block 3 from the outside of fixed block 3.It is logical
It crosses 5 micro-adjustable handle rod 4 of locking nut and stretches out the length of fixed block 3, and then pull rod 4 is made to pull the two sides of cross-beam body 1 and generate micro-
The effect of adjustment crossbeam arch deflection is played in deformation with this.
As shown in Fig. 2, adjustment component further includes Anti-loosening nut 6, two Anti-loosening nuts 6 are respectively arranged in pull rod 4
Left and right ends, and Anti-loosening nut 6 after pull rod 4 adjusts, is locked from the outer side compression locking nut 5 of locking nut 5
Anti-loosening nut 6 prevents sleeve mechanism in later period use process from loosening.
As shown in figure 3, through-hole 7 is longitudinally disposed waist-shaped hole, when cross-beam body 1 generates Light deformation, on arcuate surface 2
The inclination angle of fixed block 3 also change, therefore through-hole 7 is set as waist-shaped hole, avoids fixed block 3 and applies to the both ends of pull rod 4
Add longitudinal pressure and make pull rod 4 that flexible deformation occur, ensure that pull rod 4 can effectively be tensioned cross-beam body 1, also prolong
The service life of pull rod 4 is grown.
As shown in Fig. 2, pull rod 4 includes the mounting portion 9 of bar body 8 with the left and right ends for being connected to bar body 8,
The diameter of mounting portion 9 is less than the diameter of bar body 8, and the diameter of the diameter and through-hole 7 of mounting portion 9 matches, and mounting portion 9 protrudes into
In through-hole 7.The diameter of bar body 8 is greater than the diameter of mounting portion 9, can limit the length that mounting portion 9 stretches out through-hole 7, avoid drawing
Bar 4 excessively tense cross-beam body 1, ensure that slight deflection only occurs for cross-beam body, do not influence its horizontal supporting force and just
Property.
As shown in Fig. 2, installing two pull rods 4 in parallel on fixed block 3, two pull rods 4 are increased to cross-beam body 1
Tightening force.
As shown in figure 4, cross-beam body 1 includes outline border 10, central pipe 11 and stiffening plate 12, central pipe 11 is along level side
To running through outline border 10, muti-piece stiffening plate 12 radially connects central pipe 11 and outer on the circumferential surface of central pipe 11
Frame 10.11 structure of central pipe has extremely strong rigid non-deformability, connects on the circumferential surface of central pipe 11 multiple
Stiffening plate 12, when making 1 stress of cross-beam body, pressure relatively evenly scatter along stiffening plate 12, and ensure that crossbeam sheet
The thermal deformation resistant ability of 1 superelevation of body, it is ensured that the service precision of cross-beam body 1.Several are machined on central pipe 11 first to subtract
Repeated hole 13, stiffening plate 12 are equipped with several third lightening holes 15, and the first lightening hole 13 and third lightening hole 15 reduce crossbeam
The weight of ontology 1 improves the lightweight performance of complete machine.
As shown in Figure 1, the front of outline border 10 be equipped with horizontal guide rail 16 and with the matched sliding block of guide rail 16, sliding block and head
17 are fixedly connected, and head 17 can be moved horizontally along guide rail 16, process to the workpiece on numerically-controlled machine tool.The back side of outline border 10
Equipped with several the second lightening holes 14.
First lightening hole 13 is located at the reverse side close to outline border 10, guarantees cross-beam body 1 to its positive head 17
Support strength.
The deflection of this numerical control gantry crossbeam adjusts process are as follows: the logical of two fixed blocks 3 is inserted at the both ends of pull rod 4 respectively
In hole 7, and fixed block 3 is stretched out, tighten two locking nuts 5 in the mounting portion of pull rod 4, so that it is abutted fixed block 3, then install
Anti-loosening nut 6 prevents locking nut 5 from loosening, so that adjustment component be made to be tensioned cross-beam body 1, makes the two of its cross-beam body 1
Slight deformation occurs for end, realizes the adjustment to 1 deflection of cross-beam body.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although referring to aforementioned reality
Applying example, invention is explained in detail, for those skilled in the art, still can be to aforementioned each implementation
