Digital control machine tool with five degrees of freedom in parallel and series

Five Freedom hybrid machining tool, which relates to a five degrees of freedom CNC machine tools. The existing six degrees of freedom parallel machine tool in the processing space complex surface parts, there is a complex structure, the volume of work space and institutions than the small, complicated operation, high cost problems. Above the fixed platform of the present invention (2) located on moving platform (3) and by four telescopic rod (4) is connected between the two, four telescopic rod (4) and the upper end of the first servo motor (1) drive, connecting shaft (7) mounted on the moving platform (3) the lower end of the support wall fitted with electric spindle (6) connecting shaft (7), the lower end of the electric spindle (6) is equipped with a fixed cutter (8), two servo motors (5) and the connecting shaft (7) connected to the drive. The present invention, by the first servo motor drive four telescopic rod achieve three-dimensional movement of the movable platform rotation and one-dimensional, while the second servo motor driving the spindle and the tool is rotated relative to the moving platform, so that the hybrid machining tool can be realized on the space processing operations of complex surface parts.
