A kind of ram guide way structure
Technical field
The utility model relates to a kind of ram guide way structure, belongs to numerical control gantry machining center machine tool field.
Background technology
At numerical control gantry machining center, ram is as main motion parts, and its motion precision directly has influence on the processing quality of whole lathe. As shown in Figure 1, line slideway on existing numerical control machine tool ram arranges position and ram center and there is an eccentricity L, when lathe is in the course of processing, the cutting force that workpiece produces is reacted on ram by main shaft, online rail slide block can produce a moment, have influence on slide block work-ing life and precision, in view of this, just seem particularly important for searching out a kind of structure ram structure simple, with low cost, that can effectively alleviate lathe ram slide block force-bearing situation.
Summary of the invention
In view of this, the purpose of this utility model is to provide the ram guide way structure that a kind of structure is simple, with low cost, can effectively alleviate lathe ram slide block force-bearing situation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of ram guide way structure, comprise lathe, with the machine pillar that this lathe is connected, and the ram body being connected with this machine pillar, wherein said ram body is provided with line slideway, the side of described machine pillar is also provided with the slide of setting corresponding to described line slideway, described ram is fixedly connected with and the slide block that described line slideway is slidably matched, it is provided with main shaft bottom described ram body, the Xian Gui center of described line slideway overlaps with the alignment of shafts of described main shaft, is positioned on same vertical straight line.
Preferably, above-mentioned a kind of ram guide way structure, wherein said main shaft is arranged at the center position of described ram body.
Compared with prior art, the utility model technique effect is mainly reflected in: the utility model optimizes line slideway on ram and installs position, Xian Gui center is overlapped with the alignment of shafts bottom ram, the direction of axial cutting force is overlapped with line rail direction, additional moment can not be produced and enhance line rail slide block work-ing life, it is to increase machine tooling precision.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand and grasp.
As shown in Figure 2, a kind of ram guide way structure, comprise lathe 1, with the machine pillar 2 that this lathe 1 is connected, and the ram body 3 being connected with this machine pillar 2, wherein said ram body 3 is provided with line slideway 4, the side of described machine pillar 2 is also provided with the slide 8 of setting corresponding to described line slideway 4, described ram 8 is fixedly connected with and the slide block that described line slideway 4 is slidably matched, it is provided with main shaft 5 bottom described ram body 3, the Xian Gui center 6 of described line slideway 4 overlaps with the alignment of shafts 7 of described main shaft 5, is positioned on same vertical straight line.
In addition, main shaft 5 is arranged at the center position of described ram body 3.
This technical scheme optimize ram reach the standard grade rail install position, Xian Gui center is overlapped with the alignment of shafts bottom ram, the direction of axial cutting force is overlapped with line rail direction, additional moment can not be produced and enhance line rail slide block work-ing life, it is to increase machine tooling precision.
Certainly, being more than representative instance of the present utility model, in addition, the utility model can also have other multiple embodiment, and all employings are equal to replacement or the technical scheme of equivalent transformation formation, all drop within the claimed scope of the utility model.
