Embodiment 1

[0040] Example 1, such as Figure 1~2 As shown, the present invention provides a parallel machine tool configuration based on a 3RRRS mechanism, including a lower platform 1, an upper platform 3, a pillar 2 is arranged between the upper platform 3 and the lower platform 1, and the lower platform 1 and the upper platform 3 is arranged in a flat shape, and the pillar 2 is vertically fixed to the upper platform 3 and the lower platform 1. An installation platform 7 is set on one side of the upper plane of the lower platform 1, and a moving platform 5 is set on the other side corresponding to the installation platform 7. The lower part of the moving platform 5 is equipped with a power slider 6, and three RRRS connecting branch chains 4 are arranged between the moving platform 5 and the upper platform 3, and the described RRRS connecting branch chains 4 include an upper section unit 9, an intermediate unit 10 and a lower section unit 9. Section unit 11 and three driving motors, upp...

Embodiment 2

[0050] Embodiment 2, the projections of the upper endpoints of the three RRRS connecting branch chains 4 are triangular on the upper platform 3, the projections of the lower endpoints of the three RRRS connecting branch chains 4 are triangular on the moving platform 5, and other structures are the same Example 1.

[0051] In summary, the present invention is based on the parallel machine tool configuration of the 3RRRS mechanism, which can realize the 6-dimensional motion of the moving platform. Due to the redundant drive mode, the moving platform connected to the fixed platform has a larger working space. After installing the power slider on the moving plane, the range of machining and the poses that can be achieved are more, so the design of CNC Drilling, boring and milling machine tools have better working performance.

[0052] Due to the modular design in structure, the machine tool can meet the needs of various tasks, simplify the structure and control of the machine too...

Abstract

The invention provides a parallel machine tool based on three RRRS mechanisms. The parallel machine tool comprises a lower platform and an upper platform. Supporting columns are arranged between the upper platform and the lower platform. The lower platform and the upper platform are arranged in parallel, and the supporting columns are perpendicularly and fixedly connected to the upper platform and the lower platform. An installation platform is arranged on one side of the upper plane of the lower platform, a movable platform is arranged on the other side corresponding to the installation platform, a power sliding head is installed at the lower part of the movable platform, and three RRRS connecting chains are arranged between the moving platform and the upper platform. A control system is arranged on one side of one supporting column. By adopting the redundant drive mode, the moving platform connected with the upper platform has larger work space, wider machining range and more poses after the power sliding head is installed on the moving platform, and therefore numerically-controlled drilling, boring and milling machine tools can have better work performance. Modular design is adopted structurally, and therefore the machine tool can meet the requirements of various tasks, the structure of the machine tool can be simplified, control over the machine tool can be simplified, and the development cost and the use cost can be lowered.

Description

technical field [0001] The invention belongs to the technical field of parallel machine tools, and in particular relates to a configuration of a parallel machine tool based on a 3RRRS mechanism. Background technique [0002] Parallel machine tool is based on space parallel mechanism, which concentrates the research results of various disciplines such as mechanical engineering, computer science, electronic engineering, and automatic control.
