The invention relates to a five-degree-of-freedom parallel machine tool and belongs to the technical field of manufacturing of numerical control devices. The five-degree-of-freedom parallel machine tool comprises a moving platform provided with an electric spindle, a base, a vertical column, a top plate, a first branch chain, a second branch chain, a third branch chain, a fourth branch chain and a fifth branch chain, wherein the first branch chain, the second branch chain, the third branch chain, the fourth branch chain and the fifth branch chain are connected between the top plate and the moving platform. The top plate, the moving platform, the first branch chain, the second branch chain, the third branch chain, the fourth branch chain and the fifth branch chain form a space-in-parallel closed-loop mechanism. By driving the five branch chains, three-degree-of-freedom moving and two-degree-of-freedom rotating of the moving platform are achieved, and multi-shaft linkage machining is completed finally. The five-degree-of-freedom parallel machine tool is simple in structure, good in flexibility, high in bearing capacity and easy to control and has wide application prospects in the field of robots and high-end numerical control manufacturing equipment.
Description
technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and particularly relates to a five-degree-of-freedom parallel machine tool. Background technique [0002] In the field of modern machinery manufacturing, the structural design and processing technology of parts and components are becoming more and more complex, and the space-free surface parts have been widely used in many important fields, such as airplanes, cars, and turbine blades. In order to obtain better rotational flexibility and processing flexibility, modern machine tools should have at least five-axis linkage processing capabilities. Therefore, five-degree-of-freedom machine tools play an important role in the national economy and national security. The structure of traditional machine tools is generally in the form of series, and there are problems such as large mass of moving parts and accumulation of errors. The parallel mechanism is a closed-loop mechanism in which...
