摘要
分析了一种新型2SPS+PUP并联机床的工作空间。首先简要介绍了2SPS+PUP并联机床的结构组成,并在三维软件环境中建立了其模拟机构;其次,采用计算机辅助变量几何技术求解了2SPS+PUP并联机床的工作空间,由于机床结构的对称性,完整的工作空间可用求得一半工作空间后镜像的方法得到;最后,从位置空间和姿态角两个方面对2SPS+PUP并联机床和2SPS+UP并联机床的工作空间进行了定量比较,结果表明2SPS+PUP并联机床工作空间相对较大,具有广阔的应用前景。
The workspace of a new 2SPS + PUP parallel machine tool was analyzed. Firstly, the struc- ture of the 2SPS + PUP parallel machine tool was introduced briefly, and the simulation manipulator was built in the three dimensional software. Secondly, the workspace of the 2SPS + PUP parallel machine tool was solved using the computer aided variable geometry technique. The whole workspace can be de- rived by the mirror image method after solving the half workspace, for the symmetry structure of the ma- chine tool. Lastly, the workspaces of the 2SPS + PUP parallel machine tool and the 2SPS + UP parallel machine tool were compared from the aspects of the positional workspace and the posture angle. The re- suits show that the 2SPS + PUP parallel machine tool has a larger workspace and a wide application fu- ture.
