Cross beam assembling and adjusting device for high-precision vertical coordinate boring machine

The utility model discloses a high-precision vertical coordinate boring machine beam assembling and adjusting device which comprises a base fixedly connected with a T-shaped groove screw of a vertical coordinate boring machine workbench, a movable seat and an adjusting seat. Two transverse linear guide rails are arranged on the base, the moving seat is arranged on the base through the linear guide rails, two longitudinal linear guide rails are arranged on the moving seat, and the adjusting seat is arranged on the moving seat through the longitudinal linear guide rails; a lead screw assembly is further arranged between the two transverse linear guide rails and connected with the movable base. By adjusting two sets of devices in one type, positions in six directions such as the transverse direction, the longitudinal direction, the vertical direction, the transverse rotating direction, the longitudinal rotating direction and the vertical rotating direction of the cross beam are finely adjusted, the assembling si
