Abstract

The five-axis linkage serioparallel numerically-controlled machine tool is one kind of parallel machine tool superior to available six freedom parallel machine tool, which has high cost and complicated structure for five-axis motion. The five-axis linkage serioparallel numerically-controlled machine tool includes a frame; a moving platform; four link rods, each of which has one end connected to the frame and the other end hinged the operate moving platform; and one shifting work table set below the moving platform. The machine tool of present invention has high symmetry, high rigidity, high precision and high dynamic performance, no motion coupling, simple structure, low cost and easy manufacture. The present invention increases the structure forms of five-axis parallel machine tools, provides the theoretical research on four and five freedom parallel machine tools with mechanism prototype, and can realizes all the functions of available six freedom parallel machine tool.

Description

technical field

[0001] The invention relates to a parallel 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. In recent years, people have paid more and more attention to parallel mechanisms with few degrees of ...
