Abstract

The five freedom numerically controlled milling machine is superior to available one, which has inconvenient manufacture and installation, complicated programming, and other demerits. The five freedom numerically controlled milling machine consists of a bed, a platform pedestal, a machining tool and a main electric shaft to control the machining tool, as well as a three freedom RPS mechanism. The three freedom RPS mechanism consists of a lower platform, a moving platform and telescopic rods comprising lead screw and nut mechanism, and each of the three telescopic rods has its ends hinged separately to the lower platform and the moving platform. The milling machine of the present invention has high rigidity, high precision, simple and symmetrical structure, low cost, simple manufacture and installation, high machine accuracy and convenient programming.

Description

technical field

[0001] The invention relates to a numerically controlled milling machine. 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 wit...
