Two-dimensional high-precision worktable with grating ruler

Abstract

A two-dimensional high-precision worktable with a grating ruler comprises a motor I, a fixed seat, a grating ruler reading head, a sliding seat I, a grating head mounting support, a grating ruler seat, a motor II, the grating ruler, a grating support and a sliding seat II; the motor I is connected with the sliding seat I through a transmission mechanism I, and the grating head mounting support ismounted on the sliding seat I; the grating ruler reading head is mounted on the grating head mounting support; the grating ruler seat is mounted on the fixed seat; when the sliding seat I moves up anddown, the grating ruler reading head and the grating ruler seat make mutual movement, and the grating ruler reading head records the moving trajectory; the sliding seat II is connected with the sliding seat I through a sliding block; the motor II drives the sliding seat II through a transmission mechanism II to move relative to the sliding seat I; the grating ruler is fixed to the sliding seat I;the grating support is fixed to the sliding seat II; and when the sliding seat II moves forwards and backwards, the grating ruler records the moving trajectory. Through the two-dimensional high-precision worktable, the accurate radian feeding mode of a tile-shaped wire cutting machine can be guaranteed, and the tolerance requirement of a machined part R1 is guaranteed.

Description

technical field [0001] The invention relates to a two-dimensional high-precision workbench with a grating ruler. Background technique [0002] The feeding mode of the working table of the tile-type wire cutting machine has two movements, up and down, and forward and backward, so as to achieve the purpose of cutting arc-shaped materials. Generally, the feeding mode of the wire cutting machine table is controlled by the electric program, and the servo reducer records the displacement. During the walking process, there is no compensation movement due to the knife error. Especially when cutting arc-shaped materials, it is difficult to ensure the accuracy of the arc surface. Therefore, it is necessary to design a workbench with a grating ruler to monitor the feed trajectory of the workbench at all times and adjust the feed direction in time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-dimensional high-preci...
