| Abstract: |
A composite mechanism multi-axis machine tool includes an orthogonal coordinate feeding axis mechanism and a parallel type spatial linkage mechanism. The orthogonal coordinate feeding axis mechanism has two orthogonal platforms to provide two dimensional motion vectors. The parallel type spatial linkage mechanism has three sets of linear feeding modules engaging with a base frame for holding a main spindle which further holds a tool cutter. The parallel type spatial linkage mechanism provides one dimensional motion and two dimensional rotation for the tool cutter. A controller is provided to control and coordinate the movements of the orthogonal coordinate feeding axis mechanism and the parallel type spatial linkage mechanism. It reduces accumulation of inertia and tolerance effect, and rigidity deficiency of conventional orthogonal coordinate multi-axis machine tool, and overcomes the problems of conventional hexapod parallel type spatial linkage mechanism such as difficult for position tuning, small working space, complex control system and high cost.

First Claim:
Show all 16 claims |
What is claimed is:
1. A composite mechanism multi-axis machine tool, comprising:
- an orthogonal coordinate feeding axis mechanism having at least two movable orthogonal platforms for providing at least two dimensional vector feeding;
- a worktable mounted on the platforms and being movable with the platforms for providing at least two dimensional motion;
- a parallel type spatial linkage mechanism having a plurality of linear feeding modules, each linear feeding module includes a linear rail, wherein each linear rail is parallel to each other linear rail, a sliding block movable linearly along the linear rail and a link having one end pivotally engaged with the sliding block for giving at least one dimensional rotation and another end pivotally engaged with the base frame at a different location so that by the linear motion of the sliding blocks the base frame may perform at least two axes rotation motion;
- a machining module mounted on the base frame and facing the worktable; and
- a controller for controlling and coordinating the motion of the orthogonal coordinate feeding axis mechanism and the parallel type spatial linkage mechanism so that the machining module has a desired position and angle toward the worktable for performing machining work desired.
