Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and specifically relates to a large-swing angle gantry-type five-axis linkage hybrid machine tool, which is a multi-axis linkage that can be applied to the field of numerical control machining and can realize precision machining of slender integral structural parts with large swing angles device. Background technique [0002] The parallel mechanism is a closed-loop mechanism composed of multiple branch chains. Compared with the traditional series mechanism, the parallel mechanism has the following advantages: As a kind of manufacturing equipment with the parallel mechanism as the mechanical body, the parallel machine tool appeared in the late 1990s. With the deepening of theoretical research on parallel mechanisms and the continuous development of numerical control technology, automation technology and computer technology, parallel machine tools have gradually become an important...
