Abstract

The invention discloses a novel five-axis linkage parallel-serial numerical control machine tool, which comprises a rack, a motion platform and four connecting rods, wherein one ends of four connecting rods are all connected with the rack; the other ends of the four connecting rods are hinged with the motion platform; and a moving workbench is also arranged below the motion platform. The novel five-axis linkage parallel-serial numerical control machine tool disclosed by the invention has the advantages of good structure symmetry, better rigidity, precision and dynamic performance, simple structure and low cost and is easy to manufacture, and motion parameters are not coupled. According to the novel five-axis linkage parallel-serial numerical control machine tool disclosed by the invention, the structural mode of a five-axis parallel machine tool is enriched, and a mechanism prototype is provided for the theoretical research of four-degree-of-freedom and five-degree-of-freedom parallel mechanisms. In addition, the machine tool mechanism completely can realize functions which are owned by the traditional six-degree-of-freedom parallel machine tool mechanism, and is favorable to popularize and apply.

Description

technical field [0001] The invention relates to a parallel machine tool, in particular to a novel five-axis linkage and serial numerical control machine tool. Background technique [0002] In the past ten years, parallel machine tool has been a hot topic in the field of CNC machine tool research at home and abroad. Parallel machine tools, also known as virtual axis machine tools, are knowledge-intensive, intelligence-intensive, and technology-intensive mechatronics high-tech products. They are the intersection of multidisciplinary application technologies such as parallel robots, CNC machinery, computer control, precision measurement, and CNC machining. Scholars at home and abroad have invested a lot of research work on it. [0003] Judging from the general situation of the development of parallel machine tool products and technologies at home and abroad, most of the research in the past few years has focused on the six-degree-of-freedom parallel mechanism.
