Abstract

The invention relates to a five-axis hybrid machine tool for machining cylindrical parts. The five-axis hybrid machine tool comprises a single degree of freedom rotary head, a rotary base, a rack, a moving platform, a rotary shaft rack, a first branched chain, a second branched chain, a third branched chain and a fourth branched chain, wherein the rotary shaft rack is arranged in the rack; the moving platform is connected with the rotary shaft rack via the second branched chain and the fourth branched chain; the rotary shaft rack is connected with the rack through a revolute pair; the moving platform is connected with the rack via the first branched chain and the third branched chain; from the rack to the moving platform, the revolute pair, a moving pair, and a ball pair are sequentially distributed on the first branched chain and the third branched chain; and a hooke joint, the moving pair, and the ball pair connected with the moving platform are sequentially distributed on the secondbranched chain and the fourth branched chain. The single degree of freedom rotary head is fixedly connected with the moving platform to increase the machining angle; the rack is fixedly mounted on the rotary base, so that the machining range is expanded to the entire cylinder; and the five-axis hybrid machine tool has the advantages of being high in precision and rigidity and wide in machining range.

Description

technical field [0001] The invention relates to a five-axis mixed machine tool for processing cylindrical parts. Background technique [0002] Compared with the series mechanism, the parallel mechanism has the advantages of large load capacity (high specific stiffness), fast response speed and high motion precision, so it has attracted the attention of academia and industry, and attaches great importance to its theoretical research and application development research. The simple Parallel mechanisms have been applied for a long time, such as planar two-bar or three-bar parallel mechanisms in truss members. As mechanical equipment products, parallel mechanisms were first applied to robots. Although the parallel mechanism has the above-mentioned attractive advantages, it also has the disadvantage of small range of motion (working space), especially the limited range of motion in the return stroke. The hybrid CNC machine tool can combine the advantages of the parallel mechanis...
