Embodiment Construction

[0013] exist figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 Among them, there is a workbench 1, on which a left guide rail 7 is horizontally fixed, and a right guide rail is installed parallel to one side of the left guide rail 7. Connected together, the screw 3 cannot be tightened, and the anti-loosening screw 4 is installed at the bottom of the screw 3 to prevent the screw 3 from falling off. A guide key 5 is installed between the workbench 1 and each section of floating guide rail 2, and the guide key 5 uses a screw 6 It is fixed on the workbench 1, so that the floating guide rail 2 can move freely laterally in the direction of the guide key 5. The thermal deformation of the worktable due to heating during the working process can be freely released to ensure the grinding accuracy.

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 [0001] The invention relates to the field of machine tools, in particular to a double-V workbench guide rail device for a grinding machine. Background technique [0002] As we all know, most of the workbench guide rails of existing grinding machines are flat V structures or double V structures. But both have their own disadvantages. Because of the different structure of the guide rail, the flat V guide rail is unevenly loaded on both sides of the worktable, and the wear of the guide rails on both sides is inconsistent, which affects the accuracy of the workbench. The double V guide rail can overcome the shortcomings of the flat V guide rail, but the double V guide rail requires good straightness and parallelism, and it is difficult to process and manufacture. Even the straightness and parallelism of the double V guide rail of the workbench and the bed are very high. During the working process, due to the uneven heating of the worktable and the bed, the therm...
