Abstract
The invention relates to a working table floating guide rail device, belonging to the field of machine tool equipment. A working table is arranged on the working table floating guide rail device, a left guide rail is transversely fixed on the working table, a right guide rail is arranged at one side of the left rail in parallel and is composed of a plurality of floating guide rail sections, a gap exists between the two adjacent guide rail sections, each guide rail section is connected with the working table by a screw bolt, a guiding key is arranged on each floating guide rail section, the floating guide rail can move transversely along the direction of the guiding key and the guiding key is fixed on the working table by a screw bolt. The defects that the heat deformation quantity of a double-V guide rail on the working table of the original grinding machine can not be released transversely and the processing accuracy is affected are overcome in the invention; and meanwhile, the advantages of the double-V guide rail are kept, the structure is simple, safe and reliable.
Description
Technical field
The present invention relates to machine tool field, especially a kind of two V table slide devices of grinding machine.
Background technology
As everyone knows, the table slide of existing grinding machine mostly is flat V structure or two V structure.But the both has the drawback of oneself, and flat V guide rail is different because of its guide rail structure, workbench both sides discontinuity, and the both sides way rub is inconsistent, influences the workbench precision.Two V guide rails can overcome the shortcoming of flat V guide rail, but two V guide rails require the good linearity and the depth of parallelism, the processing and manufacturing difficulty, even if the linearity and the depth of parallelism of two V guide rails of workbench and lathe bed are very high, in the course of the work, because of workbench and lathe bed are heated inhomogeneously, the table slide temperature distortion can't discharge in a lateral direction, the lathe bed V that working table movement will be subjected to falls the horizontal inhomogeneous resistance of guide rail, influences workpiece accuracy.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of Working table floating guide rail device, thoroughly solve the problem that influences machine finish because of the table slide structure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Working table floating guide rail device, be provided with workbench, crosswise fixed has left rail on the workbench, left rail one side is parallel to be equipped with right guide rail, right guide rail is made up of several sections floating guide rails, gapped between the two neighboring sections floating guide rail, every section floating guide rail links together by screw and workbench, feather key is installed between every section floating guide rail, floating guide rail can laterally move on the direction of feather key, and feather key is fixed on the workbench through screw.
The invention has the beneficial effects as follows, overcome the two V guide rail temperature distortion amounts of former Grinder bench and can't discharge in a lateral direction, influence the shortcoming of machining accuracy; The advantage that keeps two V guide rails simultaneously; Simple in structure, safe and reliable.
