Abstract

The invention relates to a five-axle couple parallel-serial digit-control furnishing machine, wherein the fixed platform (3) is above the moveable platform (4), while they are connected via four flexible connecting rods (8); the upper ends of connecting rods (8) are geared to the first servo motor (2); the abrasive wheel (5) is mounted on the movable platform (4) to gear the movable platform (4); the fixed work bench (1) is under the abrasive wheel (5); the fixed work bench (1) is mounted with digit-control rotation table driven by the second servo motor (7). The invention can realize spatial three-dimension movement and one-dimension movement. The turbine blades mounted on the digit-control rotation table can realize one-dimension rotation. Therefore, the invention can furnish complex element.

Description

technical field [0001] The invention relates to a polishing 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. Scholars have devoted a lot of research work to 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 freedom, but most of them focus on the research on three-degree-of-freedom parallel mechanisms, while there are fewer studies on four- and five-degree-of-freedom parallel mechanisms. There a...
