Problems solved by technology

[0005] Although many scholars, schools and machine tool manufacturers at home and abroad have developed a variety of virtual axis machine tool prototypes, these virtual axis machine tool prototypes all use a six-degree-of-freedom parallel mechanism to achieve five-axis motion, which not only wastes the drive and transmission of one axis device, and relatively increase the cost of machine tools, and increase the difficulty of control and manufacturing
In addition, no five-degree-of-freedom five-axis parallel mechanism has been found at home and abroad.

Abstract

A 5-dof (degree of freedom) virtual axis machine with five axes in parallel has a structure that a moving station is connected with a fixed station by five connecting rods which are connected with the moving station by a hinge and which are connected with the fixed station by a motion cutting. Each connecting rod can be retractable or with a fixed length. The moving station is equipped with a motorized spindle and a cutting tool. The present invention has an obviously reduced systematic motion nonlinearity and coupling degree, a good processing and assembling manufacturability and low cost and can be widely applied to the processes of space curved surfaces (such as die, an impeller, a helical gear).

Description
