Abstract

The invention provides a crossbeam guide rail device. The whole rigidity of the crossbeam guide rail device is greatly improved. The crossbeam guide rail device comprises a planker, a ram, and a crossbeam, wherein the planker is arranged on the crossbeam through a sliding pair, and the crossbeam is connected with the planker through a driving mechanism. The crossbeam guide rail device is characterized in that the sliding pair comprises an upper sliding rail and a lower sliding rail, and the upper sliding rail and the lower sliding rail are respectively arranged at the top and the side of the crossbeam, and are respectively embedded in sliding grooves on the planker.

Description

(1) Technical field [0001] The invention relates to the field of machine tool beam components, in particular to a beam guide rail device. (2) Background technology [0002] The structure of the existing beam guide rail device is shown in Figure 1, which includes a carriage 4, a square ram 5 connected vertically to the middle of the carriage 4, two balance oil cylinders 7 connected to the carriage 4 and the square ram 5, and one side of the carriage 4 is flat The upper and lower parts are respectively installed with upper guide rail 2 and lower guide rail 3. The beam 1 is connected with the carriage 4 through the upper guide rail 2 and the lower guide rail 3. The feed transmission mechanism 6 is connected with the beam 1 and the carriage 4. The feed transmission mechanism 6 is installed on Between the upper guide rail 2 and the lower guide rail 3. The shortcoming of this crossbeam guide rail device is exactly because upper guide rail and lower guide rail all are in same plan...
