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

Embodiment 1

[0036] See Figure 1-9 , The moving beam locking device of the gantry five-axis machine of the present invention includes a workbench 1, a base 2, a column 3, a second guide rail 4, a beam I5, a beam II6, a first guide rail 7, a large foot iron 8, and a small foot Iron 9, chute 10, sliding block 11, hydraulic cylinder 12, bracket 13, locking pressure plate 14, bolt hole I 15, support seat 16, connecting block 17, arched door post 18, bolt hole II 19, anchor connection structure 20 , Piston rod 21, inner groove 22, bolt hole III23.

[0037] The workbench 1 slides on the first guide rail 7. A number of big foot irons 8 are arranged on the sides of the two first guide rails 7, and the first guide rail 7 is fixed on the ground by the big foot irons 8, and is arranged on the side 7 of each first guide rail. Several bases 2, two small foot irons 8 are set on the sides of the base 2, and the base 2 is fixed on the ground by the small foot irons 8. The upper end of each base 2 is provid...

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...
