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 drawback that both has oneself, flat V guide rail because of its guide rail structure different, workbench both sides discontinuity, both sides way rub is inconsistent, affects workbench precision.Two V guide rails can overcome the shortcoming of flat V guide rail, but two V guide rails require good linearity and the depth of parallelism, processing and manufacturing difficulty, even if 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 workbench and lathe bed are heated inhomogeneously, table slide temperature distortion cannot discharge in a lateral direction, the lathe bed V that working table movement will be subject to falls the horizontal inhomogeneous resistance of guide rail, affects 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 affects machine finish because of 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, on workbench, be laterally fixed with left rail, left rail one side is parallel is provided with right guide rail, right guide rail is comprised of several sections of floating guide rails, gapped between two sections of adjacent floating guide rails, every section of floating guide rail links together by screw and workbench, feather key is installed between every section of floating guide rail, floating guide rail can transverse shifting in the direction of feather key, and feather key is fixed on 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 cannot discharge in a lateral direction, affect the shortcoming of machining accuracy; Retain the advantage of two V guide rails simultaneously; Simple in structure, safe and reliable.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Fig. 4 is the partial enlarged drawing in Fig. 2.
Fig. 5 is the partial enlarged drawing in Fig. 3.
1. workbench in figure, 2. floating guide rail, 3. screw, 4. backing-up screw, 5. feather key, 6. screw, 7. left rail.
The specific embodiment
In Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, be provided with workbench 1, on workbench 1, be laterally fixed with left rail 7, left rail 7 one sides are parallel is provided with right guide rail, right guide rail is comprised of several sections of floating guide rails 2, floating guide rail 2 links together by screw 3 and workbench 1, screw 3 can not be tightened, backing-up screw 4 is arranged on the bottom of screw 3, can prevent that screw 3 from coming off, between workbench 1 and every section of floating guide rail 2, feather key 5 is installed, feather key 5 use screws 6 are fixed on workbench 1, and floating guide rail 2 can laterally move freely in the direction of feather key 5 like this.The thermal deformation that workbench is produced because being heated in the course of work freely discharges, and guarantees grinding accuracy.
