Abstract:
A gantry hybrid parallel linkage five-axis machine tool, comprising:a pedestal; a working platform secured to a surface of said pedestal; a machine framework including a planar roof and two supporting columns, said supporting columns being parallel, and having first end portions fixed to opposing sides of said pedestal, and having second end portions, each of the second end portion being provided with a respective linear guide way, said planar roof having a lower surface having sliding slots formed therein, with a respective sliding slot being formed at each end of said roof, the linear guide ways of said supporting columns being coupled with the sliding slots of said planar roof to allow said planar roof to move relative to said two columns and to make a straight linear motion in a Y-axis direction, said roof further having an upper surface having two linear guide ways thereon, said linear guide ways on said roof being perpendicular to said linear guide ways on the second end portions of said supporting columns; hood, said parallel spatial linkage mechanism including a base installed in a guide hood and a plurality of straight feeding molding units connected with said a base, each of said straight feeding molding units being rotatably hinged to said base at mutually different positions thereof, said straight feeding molding units allowing said base to be driven to make at least a two-dimensional swiveling motion; a refining molding unit installed on a side surface of said base and facing a surface of said working platform; said guide hood being separate from said planar roof, said guide hood having two sliding slots that are coupled with said two linear guide ways on said planar roof, to allow said guide hood to move in an X-axis direction; a feeding means for driving said guide hood and said planar roof in the respective X-axis and Y-axis directions; and a controller means for controlling and coordinating an operation of said straight feeding molding units of said parallel spatial linkage mechanism and said feeding means so as to change a spatial azimuth of said base thereby adjusting a relative position between said refining molding unit and said working platform.
