The invention belongs to the technical field of
machine manufacturing and particularly relates to a large-swing angle gantry type five-axis linkage serial-parallel
machine tool. The large-swing angle gantry type five-axis linkage serial-parallel
machine tool overcomes the shortcomings that the swing angles of tools of traditional numerically-controlled machine tools and existing parallel / serial-parallel machine tools are limited and the flexibility is poor and the rigidity and the accuracy are low in the process of
machining thin and long integral structural parts. The large-swing angle gantry type five-axis linkage serial-parallel
machine tool comprises a long and straight guide rail and a parallel
machining module; the parallel
machining module forms a spatial parallel
closed loop mechanism; the parallel machining module realizes two-dimensional movement of a mobile platform in the XZ plane and two-dimensional rotation of a rotation shaft in the plane of the mobile platform through four input drive, input drive enabling the parallel machining module to slide in the Y axis direction is added in the Y axis direction of the parallel machining module, and therefore the mobile platform of the parallel machining module can realize five-axis linkage movement. The large-swing angle gantry type five-axis linkage serial-parallel
machine tool has the advantages that the structure is simple, the
work space is large, the flexibility of the mobile platform is good, the rigidity and the accuracy are high, the change of drive loads in the Y axis direction is small, the dynamic property is good, the
reconfigurability is high and the modularization degree is high.
