Embodiment Construction

[0020] The specific embodiments of the present invention will be further described with reference to the drawings.

[0021] Such as figure 1 As shown, the five-axis linkage hybrid machine tool includes a long straight guide rail 1, a parallel module, a worktable 4, a fixture 3, a tool 5 and other parts. The structure of parallel modules, such as figure 2 As shown, it includes the first and third branches connecting the basic platform 6 and the moving platform 7 with the same structure, another second and fourth branch chains with the same structure, the basic platform 6 and the moving platform 7, each part forming one Space parallel closed-loop mechanism. The first chain, the second chain, the third chain, and the fourth chain all contain an actively driven movement pair, and the upper end of each branch chain and the base platform 6 and the lower end and the moving platform 7 are hinged on each platform. Arranged in equal parts at 90°. The parallel module moving platform can...

Abstract

The invention belongs to the technical field of multi-axis linkage devices, and specifically relates to a five-axis linkage hybrid machine tool, which solves the disadvantages of traditional CNC machine tools and existing hybrid machine tools in processing slender integral structural parts. It includes a long straight guide rail and a parallel module. The parallel module includes a basic platform, a moving platform and each branch chain connected between the basic platform and the moving platform. Each part forms a spatial parallel closed-loop mechanism. The parallel module moving platform can realize Two-dimensional movement in the XZ plane and two-dimensional rotation of the rotating axis in the plane of the moving platform. The parallel module is installed on a long straight guide rail along the Y-axis direction, and an active slide is added in the Y-axis direction to enable the parallel module to slide along the Y-axis direction. drive. The invention combines the advantages of traditional series machine tools and parallel machine tools, and has the advantages of large working space, high stiffness, high precision, small change in driving load in the Y-axis direction, good dynamic performance, strong reconfigurability and high degree of modularization, and can realize Five-axis simultaneous machining of complex and slender integral structural parts.

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 capable of realizing complex and slender integral structural parts that can be applied in the field of numerical control control device manufacturing. Background technique [0002] Parallel mechanism is a closed-loop mechanism composed of multiple branches. Compared with traditional series mechanism, parallel machine tool has the following advantages: Parallel machine tool appeared in the late 1990s as a manufacturing equipment with parallel mechanism as its mechanical body. With the continuous deepening of the 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 used in modern ma...
