Movable cross beam locking device of gantry five-axis machine

Abstract

The invention discloses a movable cross beam locking device of a gantry five-axis machine, which comprises a workbench, bases, uprights, second guide rails, a cross beam I, a cross beam II, first guide rails, slide grooves, slide blocks, hydraulic cylinders, brackets, locking platens, bolt holes I, support seats, connecting blocks, arched door posts, bolt holes II, anchor connecting structures, piston rods, inner grooves and bolt holes III. The device adopts the two independent cross beams; the inner grooves of the cross beams are matched with the anchor structures on the connecting blocks; the locking platens wrap the two ends of the cross beams; the hydraulic cylinders allows the piston rods to be propped against the side faces of the locking platen; the bolts are matched with the bolt holes, so that the movable cross beams and the connecting blocks form a whole; a machining precision error due to vibration in a moving process of the cross beams is avoided; at the same time, the arched door posts in the connecting blocks can bear and disperse more stress; and a deformation trend of the cross beams is reduced.

Description

Technical field [0001] The invention relates to the field of gantry milling machine tools, in particular to a movable beam locking device of a gantry five-axis machine. Background technique [0002] The gantry five-axis machine tool is a high-tech, high-precision machine tool specially used for processing complex curved surfaces. It plays an important role in the national aerospace, aviation, military, scientific research, precision equipment, high-precision medical equipment and other industries. During the machining process, the worktable moves along the guide rails to process the metal parts into the desired shape. [0003] At present, the moving beam of the gantry milling machine mainly plays the role of vertical positioning, but the moving beam will produce machining vibration during the machining process, resulting in accuracy errors. In addition, because the two ends of the beam are supported by columns, the sliding plate and ram, milling head, etc. are suspended in the midd...

Problems solved by technology

[0003] At present, the moving beam of the gantry milling machine mainly plays the role of vertical positioning, but the moving beam will generate machining vibration during processing, resulting in precision errors. In addition, since the two ends of the beam are supported by columns, the middle hangs the slide plate, ram, milling head, etc. Parts, the guide rail surface of the beam needs to bear a large gravity and turning moment, which is prone to deformation
