Abstract

The utility model relates to a floating guide rail device of a worktable, which belongs to the field of machine tool equipment and comprises a worktable. A left guide rail is transversely fixed on the worktable; a right guide rail is mounted in parallel on one side of the left guide rail and comprises a plurality of segments of floating guide rails; a gap is kept between every two adjacent segments of floating guide rails; each segment of floating guide rail is connected with the worktable through a bolt; guiding keys are mounted among segments of floating guide rails; the floating guide rails can move transversely in the direction of the guiding keys; and the guiding keys are fixed on the worktable through bolts. The utility model overcomes the defect of the conventional grinder worktable that the machining precision is affected because the thermal deformation of the double V-shaped guide rail can not release in transverse direction, keeps the advantages of the double V-shaped guide rail, and realizes simple structure and safe and reliable use.

Description

Working table floating guide rail device

Technical field

The utility model 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 utility model provides a kind of Working table floating guide rail device, thoroughly solves the problem that influences machine finish because of the table slide structure.

The technical scheme that its technical problem that solves the utility model adopts 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 beneficial effects of the utility model are, have 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.
