Large-stroke manual image measuring instrument worktable

The utility model belongs to the optical instrument technical field and relates to a large-stroke manual image measuring instrument worktable. The large-stroke manual image measuring instrument worktable comprises a mobile worktable which can move along an X direction and a Y direction, a base, a middle-layer worktable, a Y-direction transmission mechanism and an X-direction transmission mechanism, wherein the mobile worktable is in sliding connection with the middle-layer worktable along the X direction, the mobile worktable is in transmission connection with the middle-layer worktable through the X-direction transmission mechanism, the middle-layer worktable is in transmission connection with the base through the Y-direction transmission mechanism, and the X-direction movement and Y-direction movement of the mobile worktable can be controlled through respectively controlling the actions of the X-direction transmission mechanism and the Y-direction transmission mechanism. The large-stroke manual image measuring instrument worktable has the advantages of simple structure and convenient control; and the mobile worktable, the middle-layer worktable and the base are respectively made of granite, and therefore, the precision of the large-stroke manual image measuring instrument worktable is increased by 5 to 10 times compared with a worktable made of metal materials, and the large-stroke manual image measuring instrument worktable further has the advantages of easiness in processing, little possibility of deformation and high stability.
