Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
A feed drive gearing fixed by the leading screw of vertical machining centre, as shown in Figure 1, comprises elongated leading screw 1, and described leading screw 1 two ends are respectively arranged with first bearing 2 and second bearing 3 that can be fixed on lathe bed.Nut seat 5 is provided with in the middle of described leading screw 1, on described nut seat 5, one end is provided with feed screw nut 12, the other end is provided with thrust bearing 9, described thrust bearing 9 is connected with planker 8, described planker 8 is fixedly installed servomotor 4, preferably, servomotor 4 is X-axis servomotor 4, and X-axis servomotor 4 moves together along with planker 8.
The end of X-axis servomotor 4 is provided with belt wheel 7, servomotor 4 drives nut seat 5 to rotate by belt wheel 7, and the head end (left side namely in figure) of described leading screw 1 and tail end (right side namely in figure) are respectively arranged with the first prestretched nut 10 and the second prestretched nut 13.Preferably, the first prestretched nut 10 and the second prestretched nut 13 are symmetricly set on the both sides of X-axis servomotor 4.
In Fig. 1, in the middle of leading screw 1, be provided with locking nut 6, for reliably connecting between leading screw 1 and thrust bearing 9.Spacer 11 is provided with between described first prestretched nut 10 and leading screw 1, same, be provided with spacer 11 between described second prestretched nut 13 and leading screw 1.
Because leading screw 1 is directly fixed on lathe bed by first bearing 2 at two ends and the second bearing 3, therefore, when servomotor 4 drives nut seat 5 to rotate time, nut seat 5 is by generation axially-movable, and drive planker 8 to be synchronized with the movement by thrust bearing 9, and be fixed on leading screw 1 on lathe bed and carry out prestretched by the first prestretched nut 10 of head end and tail end and the second prestretched nut 13, and leading screw 1 keeps maintaining static, therefore can effectively avoid in the work of Long travel, the elongated easy thermal deformation of leading screw 1 High Rotation Speed is with bending, improve the rigidity of feeding transmission system, ensure that the service life of machining accuracy and equipment.
These are only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in the technical field that other are relevant, be all in like manner included in scope of patent protection of the present invention.
