Embodiment Construction

[0020] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0021] like figure 1 As shown, the five-axis linkage hybrid machine tool includes long straight guide rail 1, parallel module, worktable 4, fixture 3, tool 5 and other parts. where the structure of the parallel modules, such as figure 2 As shown, it includes connecting the first and third branch chains with the same structure between the basic platform 6 and the moving platform 7, and the second and fourth branch chains with the same structure, the basic platform 6 and the moving platform 7, and each part forms a Spatial parallel closed-loop mechanism. The first branch chain, the second branch chain, the third branch chain, and the fourth branch chain all contain an actively driven kinematic pair, and the hinge center points of the upper end of each branch chain with the base platform 6 and the lower end with the moving platform 7 are on each pla...

Abstract

The invention belongs to the technical field of multi-axis linkage devices and particularly relates to a five-axis linkage type hybrid machine tool. The five-axis linkage type hybrid machine tool overcomes the shortcomings of traditional numerically-controlled machine tools and existing hybrid machine tools in the process of machining long and thin integral structural members. The five-axis linkage type hybrid machine tool comprises long and straight guide rails and a parallel module; the parallel module comprises a foundation platform, a movable platform and branch chains connected between the foundation platform and the movable platform; all the parts form a spatial parallel closed loop mechanism; the movable platform of the parallel module can realize two-dimensional movement in the XZ plane and two-dimensional rotation of a rotating shaft in the movable platform; the parallel module is installed on the long and straight guide rails in the Y axis direction, and an active driver enabling the parallel module to slide in the Y axis direction is additionally arranged in the Y axis direction. The five-axis linkage type hybrid machine tool integrates the advantages of traditional serially-connected machine tools and parallel machine tools, has the advantages that the work space is large, the rigidity and the accuracy are high, the drive load change is small in the Y axis direction, the dynamic performance is good, the re-configurability is high and the modularization degree is high and can realize five-axis linkage machining of the complex long and thin integral structural members.

Description

technical field [0001] The invention belongs to the technical field of multi-axis linkage devices, and specifically relates to a five-axis linkage hybrid machine tool, which is a multi-axis linkage transposition that can be applied to the field of numerical control control device manufacturing and can realize complex and slender overall structural parts. 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 new manufacturing equipment and are us...
