A moving beam locking device for a gantry five-axis machine

Abstract

The invention discloses a moving beam locking device for a gantry five-axis machine, which includes a workbench, a base, a column, a second guide rail, a beam I, a beam II, a first guide rail, a chute, a slider, a hydraulic cylinder, a bracket, Locking platen, bolt hole I, support seat, connecting block, arched door post, bolt hole II, anchor connection structure, piston rod, inner groove, bolt hole III; the present invention adopts two separate beams, through which The combination of the inner groove of the inner groove and the anchor structure on the connecting block, the locking pressure plate wraps the two ends of the beam together, the hydraulic cylinder presses the piston rod on the side of the locking pressure plate, and the cooperation between the bolt and the bolt hole makes the beam and the connection The blocks constitute a whole, which avoids machining accuracy errors due to vibration during the movement of the beam. At the same time, the arched pillars inside the connection block can withstand and disperse more stress, reducing the tendency of the beam to deform.

Description

technical field [0001] The invention relates to the field of gantry milling machine tools, in particular to a moving beam locking device of a gantry five-axis machine. Background technique [0002] Longmen five-axis machine tool is a high-tech, high-precision machine tool specially used for processing complex curved surfaces. It plays a pivotal role in the country's aerospace, aviation, military, scientific research, precision instruments, high-precision medical equipment and other industries. During machining, the table moves along rails to machine the metal part 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 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. As a result, the guide rail surface of the beam...

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
